In recent years, unmanned aerial vehicles are increasingly widely used due to flexibility, high efficiency and persistence of unmanned aerial vehicles in performing tasks such as monitoring, investigation and attack.

The existing industry unmanned aerial vehicle charging box is in for unmanned aerial vehicle battery storage safety after being fully charged, can carry out discharge processing under the storage state after the unmanned aerial vehicle battery is not used for a long time. Under such circumstances, if the unmanned aerial vehicle is required to be used for emergency tasks, it may be found that the remaining power of the unmanned aerial vehicle battery cannot meet the requirement of the unmanned aerial vehicle for executing the emergency tasks. After the drone battery is fully charged, the stage of using the drone may have been missed.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Fig. 1 is a schematic structural diagram of an electronic device for unmanned aerial vehicle according to an embodiment of the present application. As shown in fig. 1, the apparatus includes: a controller 10, a first type of charge level 20, and a second type of charge level 30; the first type charging unit 20 and the second type charging unit 30 are respectively electrically connected with external unmanned aerial vehicle batteries; the controller 10 is configured to control the battery of the unmanned aerial vehicle electrically connected to the first type charging level 20 to be maintained above a preset electric quantity; the preset electric quantity is determined according to the electric quantity required by the unmanned aerial vehicle to execute the appointed task; and when the battery of the unmanned aerial vehicle electrically connected with the second type charging battery 30 meets the preset discharging condition, discharging treatment is carried out in a storage state.

In particular, the battery management device for an unmanned aerial vehicle provided in this embodiment includes a plurality of charging cells 40, wherein one portion of the plurality of charging cells 40 is used as the first type charging cell 20, and the other portion is used as the second type charging cell 30. Specifically, which part of the plurality of charging bits 40 is the first type of charging bit and which part of the plurality of charging bits is the second type of charging bit 30 may be fixedly designated or dynamically designated, which is not limited herein. How to implement the fixed or dynamic assignment of the first type of charging bit as well as the second type of charging bit can be seen in the following relevant matters.

Based on the above, the controller 10 may further be configured to: at least one of the first type of charging bit and at least one of the second type of charging bit are determined from the plurality of charging bits. Specifically, the controller 10 may determine at least one first type of charging level and at least one second type of charging level from the plurality of charging levels according to the acquired attribute information of the plurality of charging levels. Wherein, the attribute information comprises a type identifier to which the charging bit belongs; the type identifier can be configured for the charging bit in advance in the design of a plurality of charging bit stages, so that fixed specification of the first type charging bit and the second type charging bit in the plurality of charging bits is realized. Of course, other ways of determining the first type of charging level and the second type of charging level may be adopted in addition to the above way, for example, a button may be set on the battery management device of the unmanned aerial vehicle, and the controller may determine the first type of charging level and the second type of charging level from the plurality of charging levels according to the obtained pressing operation data of the button by the user, so as to realize dynamic assignment of the first type of charging level and the second type of charging level. Namely:

In some embodiments, a second key (not shown in the drawings) may be further disposed on the battery management device of the unmanned aerial vehicle. Accordingly, the controller 10 may also be configured to: and determining at least one first type charging bit and at least one second type charging bit from the plurality of charging bits according to the pressing operation data related to the second key.

In the implementation, the controller may determine the charging position selected by the user according to the obtained number of continuous pressing operations performed on the second key by the user, and use the charging position selected by the user as the first type charging position, and the remaining non-selected charging positions as the second type charging position, so as to determine at least one first type charging position and at least one second type charging position from the plurality of charging positions.

For example: referring to the 4 charge bits 40 shown in fig. 1, charge bit 41 is considered a first charge bit, charge bit 42 is considered a second charge bit, and the remaining charge bits are analogized in order according to the arrangement order of the 4 charge bits 40. For example, when the user performs the first pressing operation on the second key, it may be determined that the user has selected the first charging level, and accordingly, the charging level 41 is the first type charging level, and the charging level 42, the charging level 43, and the charging level 44 are the second type charging levels; then, if the user continues to press the second key for the second time, it can be determined that the user selects the first charging bit and the second charging bit at the same time, and accordingly, the charging bit 41 and the charging bit 42 are the first type charging bit at this time, and the charging bit 43 and the charging bit 44 are the second type charging bit; and so on.

What should be stated here is: the type of the charging bit can be indicated by an indicator lamp of the corresponding charging bit. That is, the unmanned aerial vehicle battery management apparatus of the present embodiment may further include: the plurality of indicator lamps (not shown in the drawing) respectively corresponding to the plurality of charging positions are electrically connected with the controller 10, and the indicator lamps can be used for indicating the current type of the corresponding charging positions, so that a user can clearly know which charging positions are the first type charging positions and which charging positions are the second type charging positions through the light color displayed by the indicator lamps. For example, the light color displayed by the indicator lamp corresponding to the charging bit 41 is red, which indicates that the charging bit 41 is a first type charging bit; the indicator light corresponding to the charging bit 42 shows a green light, indicating that the charging bit 42 is a second type of charging bit.

Fig. 1 shows a case where the battery management device of the unmanned aerial vehicle includes 4 charging bits, wherein the charging bit 41 is a first type charging bit, and the charging bits 42, 43 and 44 are second type charging bits. It should be noted that the number of charging bits and the numbers of the first type charging bits and the second type charging bits shown in fig. 1 are only schematic and do not represent actual numbers.

On the basis of determining the first type charging level and the second type charging level, further, the controller 10 can be used for controlling the unmanned aerial vehicle battery electrically connected with the first type charging level to be kept above the preset electric quantity, so that part of the unmanned aerial vehicle battery can keep higher electric quantity, namely higher state of charge SOC (State of Charge), and emergency requirements of the unmanned aerial vehicle can be met. In specific implementation, the preset electric quantity can be flexibly determined according to the electric quantity required by the unmanned aerial vehicle to execute the specified task, for example, the preset electric quantity can be 90%, 95% or the like, which is not limited herein. And for the unmanned aerial vehicle battery electrically connected with the second type of charging potential, when the battery meets the preset discharging condition, discharging treatment in a storage state can be performed so as to safely store. For how to keep the battery of the unmanned aerial vehicle electrically connected to the first type of charging potential above a preset amount of electricity and to discharge the battery of the unmanned aerial vehicle electrically connected to the second type of charging potential, see the following.

In practical application, a discharging circuit is built in the unmanned aerial vehicle battery, and the discharging circuit can be used for discharging. Or, the charging potential can be provided with a discharging circuit, and the unmanned aerial vehicle battery can also be discharged by using the discharging circuit arranged on the charging potential. That is, when the battery of the unmanned aerial vehicle electrically connected with the charging place satisfies the discharging condition, the controller closes the discharging circuit provided on the charging place to control the battery of the unmanned aerial vehicle to discharge. Based on this, that is, the unmanned battery management apparatus provided in the present embodiment may further include: and the discharging circuits are respectively and electrically connected with the charging potentials, and are electrically connected with the controller, and the controller can control the discharging circuits electrically connected with the discharging circuits so as to keep the discharging circuits in an open state or a closed state. In specific implementation, according to actual requirements, the controller corresponds to different control schemes for the discharge circuits of different types of charging potentials in the plurality of charging potentials. In particular, the method comprises the steps of,

For a first type of charging bit of a plurality of charging bits

Referring to fig. 2, the battery management device for an unmanned aerial vehicle provided in this embodiment may further include: a first discharge circuit 210 electrically connected to the first type of charge bit 20, the first discharge circuit 210 being electrically connected to the controller 10. Accordingly, the controller 10 is particularly useful for: and in the process of electrically connecting the first type of charging potential with the unmanned aerial vehicle battery, controlling the first discharging circuit to keep an off state. The first discharge circuit is controlled to maintain the off state, so as to disable the first discharge circuit, and avoid the first discharge circuit discharging the unmanned aerial vehicle battery electrically connected with the first type charging potential.

The first discharging circuit is controlled to keep the disconnected state, and the first discharging circuit can be prevented from discharging the unmanned aerial vehicle battery electrically connected with the first type charging potential, but the unmanned aerial vehicle battery can also have chemical self-discharge, so that the problem of electric quantity loss of the unmanned aerial vehicle battery electrically connected with the first type charging potential still exists. In order to enable the electric quantity of the unmanned aerial vehicle battery electrically connected with the first type charging potential to be kept above the preset electric quantity for a long time, the electric quantity of the unmanned aerial vehicle battery electrically connected with the first type charging potential needs to be detected, so that when the electric quantity of the unmanned aerial vehicle battery electrically connected with the first type charging potential is detected to be lower than the preset electric quantity, the first type charging potential is controlled to charge the unmanned aerial vehicle battery electrically connected with the first type charging potential to be above the preset electric quantity. Accordingly, with continued reference to fig. 2, the battery management device for an unmanned aerial vehicle provided in the present embodiment may further include: a power detection unit 220 electrically connected to the first type charging bit 20 and a first charging circuit 230; wherein,

The electric quantity detection unit 220 is configured to detect an electric quantity of a battery of the unmanned aerial vehicle electrically connected to the first type charging potential; the electric quantity detection unit 220 is electrically connected with the controller 10; in response to this, the control unit,

the controller 10 is specifically configured to: when the electric quantity detection unit detects that the electric quantity of the unmanned aerial vehicle battery electrically connected with the first type charging potential is lower than the preset electric quantity, the first charging circuit is controlled to charge the unmanned aerial vehicle battery electrically connected with the first type charging potential to above the preset electric quantity.

In the implementation, the electric quantity detection unit can be used for detecting the unmanned aerial vehicle battery electrically connected with the first type of charging potential in real time, or can also be used for detecting at intervals of a preset time period; the preset period of time may be two days, five days, etc., and is not limited herein. When the electric quantity of the unmanned aerial vehicle battery electrically connected with the first type charging potential is detected to be lower than the preset electric quantity, the first type charging potential can be controlled to charge the unmanned aerial vehicle battery (hereinafter referred to as a first type unmanned aerial vehicle battery) electrically connected with the first type charging potential to be higher than the preset electric quantity in a constant current charging mode. And after the first type charging level is that the first type unmanned aerial vehicle battery is charged to be above the preset electric quantity, if any operation is not performed on the first type unmanned aerial vehicle battery for a period of time, for example, no operation such as discharging or using the first type unmanned aerial vehicle battery is performed within 24 hours, the first type unmanned aerial vehicle battery enters a standby mode. The standby mode refers to that the electric quantity of the first type unmanned aerial vehicle battery is always above the preset electric quantity, for example, the preset electric quantity is set to 90%, after the first type charging electric quantity is charged to 95% by adopting a constant current mode, if no operation is performed on the first type charging electric quantity within 24 hours, the electric quantity of the first type unmanned aerial vehicle battery is always above 90%, that is, the first type unmanned aerial vehicle battery is always kept in a high SOC state, so that the first type rechargeable battery is in a ready-to-use state, and therefore, when an emergency task exists, the first type unmanned aerial vehicle battery can be immediately utilized to supply power for the unmanned aerial vehicle, and the emergency basic requirement of the unmanned aerial vehicle is met. When an emergency task exists, the battery of the unmanned aerial vehicle electrically connected with the second type of charging potential can be controlled to charge the corresponding battery of the unmanned aerial vehicle rapidly. For specific control of the second type of charging potential for charging the corresponding unmanned aerial vehicle battery, see below.

For a second type of charging bit of the plurality of charging bits

Referring to fig. 3, the battery management device for an unmanned aerial vehicle provided in this embodiment may further include: a second discharge circuit 310 electrically connected to the second type of charge bit; the second discharging circuit 310 is electrically connected to the controller 10; in response to this, the control unit,

the controller 10 is specifically configured to: and when the battery of the unmanned aerial vehicle electrically connected with the second type of charging potential meets the discharging condition, controlling the second discharging circuit to be closed so as to perform discharging treatment on the battery of the unmanned aerial vehicle electrically connected with the second type of charging potential in a storage state.

The above-mentioned discharging condition may refer to a preset condition related to a storage period, for example, when the storage period of the unmanned aerial vehicle battery electrically connected to the second type of charging potential is detected to be longer than a preset period threshold, it may be determined that the unmanned aerial vehicle battery electrically connected to the second type of charging potential meets the discharging condition; the storage time length of the unmanned aerial vehicle battery electrically connected with the second type of charging position can be obtained through the data detected by the related detecting unit (such as the battery in-place detecting unit). Based on this, in a specific implementation technical solution, the battery management device for an unmanned aerial vehicle provided in this embodiment may further include: a battery in-place detecting unit 320 electrically connected to the second type of charging place; the battery in-place detection unit 320 is electrically connected to the controller 10. In response to this, the control unit,

The controller 10 is further specifically configured to: combining the detection data of the battery in-situ detection unit to determine whether the storage duration of the battery of the unmanned aerial vehicle electrically connected with the second type charging level in the second type charging level exceeds a preset duration threshold; and when the storage time length exceeds the preset time length threshold, judging that the battery of the unmanned aerial vehicle electrically connected with the second type of charging potential meets the discharging condition.

In particular, the above-mentioned storage duration refers to a duration during which no operation is performed on the unmanned aerial vehicle battery electrically connected to the second type of charging potential, and the operation may include, but is not limited to: plugging, charging, discharging and the like. The preset time threshold can be flexibly determined according to practical situations, for example, the preset time can be specifically 7 days, one month, etc., which is not limited herein. When the storage time exceeds the preset time threshold, the controller can control the second discharging circuit to be closed so as to perform discharging treatment on the unmanned aerial vehicle battery electrically connected with the second type charging potential in a storage state, so that the unmanned aerial vehicle battery electrically connected with the second type charging potential releases certain electric quantity. For example, taking a preset time period threshold value as 7 days as an example, the initial electric quantity of an unmanned aerial vehicle battery (hereinafter referred to as a second type unmanned aerial vehicle battery) electrically connected with the second type charging potential is full electric quantity, when the storage time period of the second type unmanned aerial vehicle battery reaches 7 days, the controller can control the second discharging circuit to be closed so that the second type unmanned aerial vehicle battery releases 10% of the electric quantity, and at the moment, the residual electric quantity of the second type unmanned aerial vehicle battery is 90%; in the following, if the storage duration of the battery reaches the preset duration threshold again, the second discharging circuit can be used for discharging the second type unmanned aerial vehicle battery again, so that 10% of electric quantity is released again, and the like. The description is as follows: when the storage duration reaches the preset duration threshold value, the electric quantity released each time may be the same or different, which is not limited herein.

In the unmanned aerial vehicle battery management device provided by the embodiment, the second type of charging potential is provided with a plurality of second type of charging potentials, the plurality of second type of charging potentials are respectively and electrically connected with the external unmanned aerial vehicle battery, and the plurality of second type of charging potentials can respectively charge the unmanned aerial vehicle battery electrically connected with the second type of charging potentials by using the second charging circuits arranged on the second type of charging potentials. When the plurality of second type charging cells are respectively used for charging the unmanned aerial vehicle battery which is electrically connected with the second type charging cells, the situation that the battery of the unmanned aerial vehicle is possibly damaged when the battery of the unmanned aerial vehicle is charged in the too high or too low state is considered, and the battery charging efficiency, the service life and the use safety of the unmanned aerial vehicle battery are affected. Therefore, in order to avoid damage to the unmanned aerial vehicle battery, the unmanned aerial vehicle battery with the temperature within the working allowable range of the unmanned aerial vehicle battery can be charged preferentially, and the temperature of the unmanned aerial vehicle battery can be detected by the temperature sensor. That is, further, the battery management device for an unmanned aerial vehicle provided in the present embodiment may further include: a plurality of second charging circuits 330 electrically connected to the plurality of second type charging stations, respectively, and a plurality of temperature sensors 340 located at the plurality of second type charging stations, respectively; the plurality of second charging circuits 330 are respectively connected to the controller 10; the plurality of temperature sensors 340 are respectively connected to the controller 10; the temperature sensor 340 is configured to detect a temperature of the battery of the unmanned aerial vehicle electrically connected to the corresponding charging station. In response to this, the control unit,

The controller 10 is further configured to: after receiving the charging instruction, determining the charging sequence of the unmanned aerial vehicle battery electrically connected with each of the plurality of second type charging cells according to the temperature of the unmanned aerial vehicle battery electrically connected with each of the plurality of second type charging cells; and according to the charging sequence, controlling the plurality of second charging circuits to charge the plurality of second-type battery cells which are electrically connected with each other.

Here in order to guarantee in a first way that can satisfy the emergent basic demand of unmanned aerial vehicle, after the controller received the instruction of charging, will be prioritized control with first type charge the battery charging to corresponding unmanned aerial vehicle battery with the first charging circuit who is connected to the electric charge of first type to above predetermineeing the electric quantity. Namely, the controller 10 can be specifically used for:

after receiving the charging instruction, controlling a first charging circuit electrically connected with the first type charging potential to charge the unmanned aerial vehicle battery electrically connected with the first type charging potential to a preset electric quantity or more;

and after the battery of the unmanned aerial vehicle electrically connected with the first type charging potential is charged, controlling the plurality of second charging circuits to charge a plurality of battery of the unmanned aerial vehicle electrically connected with the second type charging according to the charging sequence.

In specific implementation, the method for controlling the first charging circuit electrically connected to the first type charging potential to charge the unmanned aerial vehicle battery electrically connected to the second type charging potential to a level above a preset electric quantity can be referred to above or below, and detailed description thereof is omitted herein. In addition, when determining the charging order of the unmanned aerial vehicle battery electrically connected to each of the plurality of second-type charging cells according to the acquired temperature of the unmanned aerial vehicle battery electrically connected to each of the plurality of second-type charging cells, the controller 10 determines that the charging order of the unmanned aerial vehicle battery having a temperature within the safe charging temperature range is earlier than the charging order of the unmanned aerial vehicle battery having a temperature outside the safe charging range. The safe charging temperature range is determined according to the performance of the unmanned aerial vehicle battery, for example, the safe charging temperature range may be: the temperature is not limited to 20℃to 45 ℃.

For example, referring to fig. 1, the second type of charging bit shown in fig. 1 includes: the charging station 42, the charging station 43 and the charging station 44 are respectively provided with corresponding temperature sensors, and the controller determines that the temperature of the unmanned aerial vehicle battery respectively electrically connected with the charging station 42 and the charging station 43 is in a safe charging range and the temperature of the unmanned aerial vehicle battery electrically connected with the charging station 44 is out of the safe charging range according to the received temperatures of the corresponding unmanned aerial vehicle batteries detected by the charging station 42, the charging station 43 and the temperature sensors on the charging station 44. When the controller receives the charging instruction, it may preferably control the charging electric potential 42 and the charging electric potential 43 to charge the respective unmanned aerial vehicle batteries electrically connected thereto, and then control the charging electric potential 44 to charge the unmanned aerial vehicle batteries electrically connected thereto. When the charging potential 42 and the charging potential 43 are specifically controlled to charge the unmanned aerial vehicle battery respectively electrically connected with the charging potential 42 and the charging potential 43, the battery charging sequence of the unmanned aerial vehicle battery respectively electrically connected with the charging potential 42 and the charging potential 43 can be determined according to the voltage of the unmanned aerial vehicle battery; the higher the voltage of the unmanned aerial vehicle battery, the higher the corresponding charging priority. The reason for this is that: the higher the voltage of the unmanned aerial vehicle battery is, the more the residual electric quantity of the unmanned aerial vehicle battery is, the electric quantity required by the unmanned aerial vehicle to execute the task can be reached quickly when the unmanned aerial vehicle battery is charged, so that the charging efficiency can be effectively accelerated, and the charging time is shortened.

Based on this, that is, further, the battery management device for an unmanned aerial vehicle provided in the present embodiment may further include: a plurality of voltage detection units 350 respectively located at a plurality of the second type charging bits; the voltage detection unit 350 is configured to detect a voltage of the unmanned aerial vehicle battery electrically connected to the corresponding charging potential; the plurality of voltage detection units 350 are electrically connected to the controller 10, respectively. In response to this, the control unit,

the controller 10 is specifically configured to:

determining at least one first unmanned aerial vehicle battery with the temperature within the safe charging range and at least one second unmanned aerial vehicle battery with the temperature outside the safe charging range according to the temperatures of the unmanned aerial vehicle batteries electrically connected with the second type charging positions;

determining a charging sequence of the at least one first unmanned aerial vehicle battery according to the voltage of the at least one first unmanned aerial vehicle battery;

determining a charging sequence of the at least one second unmanned aerial vehicle battery according to the voltage of the at least one second unmanned aerial vehicle battery;

in the charging sequence, the charging sequence of the at least one first unmanned aerial vehicle battery is earlier than the charging sequence of the at least one second unmanned aerial vehicle battery.

With continued reference to fig. 1 and with the above example, the temperature of the drone battery to which each of the charging bit 42 and the charging bit 43 in fig. 1 is connected is set to be within a safe temperature range, and the temperature of the drone battery to which the charging bit 44 is electrically connected is set to be outside the safe temperature range, i.e., the charging order of the drone battery to which each of the charging bit 42 and the charging bit 43 is electrically connected is earlier than the charging order of the drone battery to which the charging bit 44 is electrically connected. In this case, if the controller determines that the voltage of the unmanned aerial vehicle battery electrically connected to the charging station 42 is higher than the voltage of the unmanned aerial vehicle battery electrically connected to the charging station 43 according to the received voltage data of the unmanned aerial vehicle batteries electrically connected to the charging stations, detected by the voltage sensors respectively located on the charging station 42 and the charging station 43, the charging sequence of the unmanned aerial vehicle battery electrically connected to the charging station 42 is earlier than the charging sequence of the unmanned aerial vehicle battery electrically connected to the charging station 43. In summary, the charging sequence of the unmanned aerial vehicle battery determined by the controller and electrically connected to the charging station 42, the charging station 43 and the charging station 44 is as follows: unmanned aerial vehicle battery with charging potential 42 electrically connected and with charging potential 43 electrically connected and with charging potential 44 electrically connected; accordingly, when the controller controls the charging electric potential 42, the charging electric potential 43 and the charging electric potential 44 to charge the corresponding unmanned aerial vehicle battery according to the determined charging sequence, respectively, the controller will first control the second charging electric potential 42 to charge the unmanned aerial vehicle battery electrically connected to the charging electric potential 42, then control the second charging electric potential 43 to charge the unmanned aerial vehicle battery electrically connected to the charging electric potential 43, and finally control the second charging electric potential 44 to charge the unmanned aerial vehicle battery electrically connected to the charging electric potential 44.

Further, in the process of controlling the plurality of second charging circuits to charge the plurality of second type charging cells electrically connected to the unmanned aerial vehicle battery according to the determined charging sequence of the plurality of second type charging cells, the controller 10 may specifically further control the plurality of second charging circuits to charge the corresponding unmanned aerial vehicle battery according to the charging modes corresponding to the plurality of second type charging cells based on the charging modes corresponding to the plurality of second type charging cells. The charging mode can be flexibly set according to different task scenes of unmanned aerial vehicle application. For example, when the unmanned aerial vehicle is applied to a scene without an emergency task (such as aerial photography and mapping), the charging time of the battery of the unmanned aerial vehicle is generally not required, and for this purpose, a plurality of charging modes corresponding to the second type charging positions can be set to be slow charging modes; when the unmanned aerial vehicle is applied to scenes with emergency tasks (such as forest disaster relief and police), the unmanned aerial vehicle battery is required to be charged in a short time, and therefore a plurality of charging modes corresponding to charging positions can be set to be quick charging modes, so that the charging time of the unmanned aerial vehicle battery is shortened. For details of the slow charge mode and the fast charge mode, reference will be made to the following relevant matters, and details will not be repeated here.

That is, in some embodiments, the controller 10 described above may be specifically configured to:

determining charging modes corresponding to a plurality of second type charging potentials; the charging mode comprises a slow charging mode or a fast charging mode;

and controlling the plurality of second charging circuits to charge the unmanned aerial vehicle battery which is electrically connected with the corresponding second type charging potential according to the charging sequence and the charging mode.

Generally, the battery charging process is divided into two phases: a constant current charging phase and a constant voltage charging phase. The charging sequence of each battery is as follows: constant current charging is performed first, and then constant voltage charging is performed. Among them, the constant voltage charging phase takes the longest time. Generally, at the end of the constant current charging phase, the electric quantity of the battery is more than 90%, and the battery can be put into use to meet emergency demands.

In specific implementation, the slow charging mode refers to sequentially performing constant current and constant voltage charging on the unmanned aerial vehicle battery electrically connected with the plurality of charging positions according to the charging sequence of the battery of the unmanned aerial vehicle electrically connected with the plurality of charging positions; the fast mode refers to that constant current charging is carried out on the unmanned aerial vehicle batteries electrically connected with the charging positions in sequence according to the charging sequence of the unmanned aerial vehicle batteries electrically connected with the charging positions, and after the constant current charging of the unmanned aerial vehicle batteries electrically connected with the charging positions is finished, the constant voltage charging is carried out on the unmanned aerial vehicle batteries electrically connected with the charging positions in sequence.

For example: continuing with the example described above with respect to fig. 1, fig. 1 shows a charging sequence for the unmanned aerial vehicle battery in which each of the plurality of second type charging stations (i.e., charging station 42, charging station 43, and charging station 44) is electrically connected as follows: unmanned aerial vehicle battery with charging potential 42 electrically connected to unmanned aerial vehicle battery with charging potential 43 electrically connected to unmanned aerial vehicle battery with charging potential 44 electrically connected to charging potential 43. If the charging modes corresponding to the charging position 42, the charging position 43 and the charging position 44 are slow charging modes, the controller firstly controls a second charging circuit on the charging position 42 to charge the unmanned aerial vehicle battery electrically connected with the charging position 42 to 90% in constant current and then charges to 100% in constant voltage after receiving the charging instruction; after the unmanned aerial vehicle battery electrically connected with the charging position 42 is charged, the controller 10 then controls the second charging circuit on the charging position 43 to charge the unmanned aerial vehicle battery electrically connected with the charging position 43 to 90% by constant current, and then charges to 100% by constant voltage; and so on until the unmanned aerial vehicle battery electrically connected to the charging potential 44 is charged. If the charging bit patterns corresponding to the charging bit 42, the charging bit 43 and the charging bit 44 are the fast charging mode, the controller sequentially controls the second charging circuit of the charging bit 42 to charge the constant current of the unmanned aerial vehicle battery electrically connected to the charging bit 42 to 90%, the second charging circuit of the charging bit 43 to charge the constant current of the unmanned aerial vehicle battery electrically connected to the charging bit 43 to 90%, and the second charging circuit of the charging bit 44 to charge the constant current of the unmanned aerial vehicle battery electrically connected to the charging bit 44 to 90% after receiving the charging command; then, the second charging circuit sequentially controlling the charging position 42 is returned to charge the battery constant voltage of the unmanned aerial vehicle electrically connected to the charging position 42 to 100%, the second charging circuit of the charging position 43 is charged to charge the battery constant voltage of the unmanned aerial vehicle electrically connected to the charging position 43 to 100%, and the second charging circuit of the charging position 44 is charged to charge the battery constant voltage of the unmanned aerial vehicle electrically connected to the charging position 44 to 100%.

What should be stated here is: based on the above, in order to ensure that the unmanned aerial vehicle can meet the emergency requirement preferentially, the controller controls the first charging circuit electrically connected with the first type charging potential to charge the unmanned aerial vehicle battery electrically connected with the corresponding first type charging potential preferentially after receiving the charging instruction. For this reason, in the above example, when the charging mode is the slow charging mode, after receiving the charging command, the controller 10 charges the first charging circuit that preferentially controls the first type of charging potential (i.e. the charging potential 41) to 90% of the constant-current charging of the unmanned aerial vehicle battery electrically connected to the corresponding charging potential 41, and then charges to 100% of the constant-voltage charging. After the battery of the unmanned aerial vehicle electrically connected with the charging station 41 is charged, the battery of the unmanned aerial vehicle electrically connected with the corresponding charging stations is controlled to be charged according to the charging sequence and the slow-charging mode of the unmanned aerial vehicle electrically connected with the plurality of second-type charging stations (namely the charging station 42, the charging station 43 and the charging station 44) respectively, and the second charging circuit electrically connected with the charging station 42, the charging station 43 and the charging station 44 respectively. When the charging mode is the fast mode, the controller 10 charges the constant current of the unmanned aerial vehicle battery electrically connected to the corresponding charging level 41 by the first charging circuit which is preferentially controlling the first type charging level (i.e. charging level 41) to 90% after receiving the charging command, and then sequentially controls the constant current of the unmanned aerial vehicle battery electrically connected to the corresponding charging level by the second charging circuits which are electrically connected to the plurality of second type charging levels (i.e. charging level 42, charging level 43 and charging level 44) to 90% respectively; after the constant-current charging of the unmanned aerial vehicle battery with the first type charging level and the plurality of second type charging levels is completed, the unmanned aerial vehicle battery with the first type charging level and the plurality of second type charging levels is returned to control the charging level 41 to be electrically connected with the first discharging circuit to charge the constant voltage of the unmanned aerial vehicle battery with the charging level 41 to 100%, and then control the charging level 42, the charging level 43 and the second discharging circuit with the charging level 44 to charge the corresponding charging level to the constant voltage of the unmanned aerial vehicle battery with the charging level to 100% respectively. Details not specifically described in this example are referred to above.

From the above, the fast charge mode can ensure that more batteries meeting emergency requirements can be used as soon as possible.

What should be stated here is also: the above first type charging unit may also have a plurality of charging sequence determining modes of the unmanned aerial vehicle battery electrically connected to the plurality of first type charging units when the plurality of first type charging units are provided, and the charging sequence determining modes of the unmanned aerial vehicle battery electrically connected to the plurality of second type charging units will not be described herein.

Further, in some embodiments, the battery management device of the unmanned aerial vehicle provided in this embodiment may be provided with a first key (not shown in the drawing) corresponding to each of the plurality of charging positions. The charging modes corresponding to the plurality of second type charging bits can be controlled through the corresponding first keys. Specifically, according to the application scene of the unmanned aerial vehicle, a user can realize the switching of the charging modes corresponding to the corresponding second type charging level by long-pressing the first key; correspondingly, the controller can determine the charging mode corresponding to the corresponding second type charging bit according to the obtained pressing operation data related to the first key. It can be seen that in this way,

I.e., the controller 10, may also be specifically configured to: and determining the charging modes corresponding to the plurality of second-type charging bits according to the pressing operation data of the first keys corresponding to the plurality of second-type charging bits.

In the implementation, after the long-press operation duration of the first key by the user reaches the set duration, the charging mode corresponding to the corresponding second type charging bit can be switched once. That is, the controller may determine the charging mode corresponding to the corresponding second type of charging level according to the long-press operation data of the user on the first key. For example, assuming that the set duration is 3s, the default charging mode of each second type of charging bit is a slow charging mode, when the user presses the first key for 3s for a long time, the charging mode of the corresponding second type of charging bit is switched to a fast charging mode, and then if the user presses the first key for 3s again, the charging mode of the corresponding second charging bit is switched to the slow charging mode.

In practical application, three charging modes can be set for each charging bit: slow charge mode, fast charge mode, and standby mode. When the charging mode of a certain charging bit is a slow charging mode or a fast charging mode, the charging bit is a second type charging bit; when the charging mode of a certain charging bit is the standby mode, the charging bit is the first type charging bit. That is, the user can determine the type of the charging bit and the charging mode through the first key corresponding to each charging bit. For example: assuming that the set duration is 3s, the default charging mode of each charging bit is a slow charging mode, and when a user presses a first key for 3s for a long time, the charging mode of the corresponding charging bit is switched into a fast charging mode; then, if the user presses the first key for 3 seconds again, the charging mode of the corresponding charging bit is switched to enter a standby mode; and if the user presses the first key for 3 seconds again, the charging mode of the corresponding charging bit is switched to enter a slow charging mode.

What should be stated here is: after the user completes the switching of the charging modes corresponding to the plurality of second-type charging bits, the controller 10 may further control a plurality of indicator lamps corresponding to the plurality of charging bits to indicate the charging mode corresponding to the current corresponding charging bit. Different charging modes can be characterized by different light colors; for example, the light color displayed by the indicator light is yellow, so that the charging mode corresponding to the corresponding charging position can be represented as a standby mode; if the light color displayed by the indicator lamp is green, the charging mode corresponding to the corresponding charging position can be represented as a quick charging mode; the light color displayed by the indicator light is red, so that the charging mode corresponding to the corresponding charging position can be represented as a slow charging mode. Furthermore, since the charging mode is related to the type, the light color displayed by the indicator light can also characterize the type of the corresponding charging bit. Of course, other light colors may be used to represent different charging modes, which is not limited in this embodiment.

Still further, the first key may have a function of checking the electric quantity of the unmanned aerial vehicle battery, in addition to a function of switching the charging mode corresponding to the corresponding charging position. That is, in some embodiments, the first key may also be used to view the power of the drone battery. The key is multiplexed, so that the structure of the battery charge management device of the unmanned aerial vehicle can be simplified, and the cost is reduced.

In the implementation, the user can check the electric quantity of the unmanned aerial vehicle battery by performing short-press operation on the first key. Specifically, the battery management device for an unmanned aerial vehicle provided in this embodiment may further include a display, where the display may be connected to the controller 10, and the display may be used to display the amount of power of the battery for the unmanned aerial vehicle to which the charging potential is electrically connected. For example, when the user performs a short-press operation on the first key, the controller may control the display to display the electric quantity of the unmanned aerial vehicle battery electrically connected to the corresponding charging bit after receiving the short-press operation data related to the first key. In addition, in the case of the optical fiber,

the technical scheme provided by the embodiment is that the unmanned aerial vehicle battery management device comprises a controller, a first type charging level and a second type charging level; the first type charging potential and the second type charging potential are respectively and electrically connected with an external unmanned aerial vehicle battery; the controller can be used for controlling the unmanned aerial vehicle battery electrically connected with the first type charging potential to be kept above a preset electric quantity; the preset electric quantity is determined according to the electric quantity required by the unmanned aerial vehicle to execute the appointed task; and when the battery of the unmanned aerial vehicle electrically connected with the second type of charging potential meets the preset discharging condition, discharging treatment is carried out in a storage state. According to the scheme, on one hand, the unmanned aerial vehicle battery which is at least electrically connected with the first type charging potential is kept in a high SOC state for a long time through the first type charging potential, so that the unmanned aerial vehicle can meet the basic emergency requirement, and the user experience is improved; the other party can make the unmanned aerial vehicle battery electrically connected with the second type charging potential meet the preset condition through the second type charging potential, and discharge processing is carried out in a storage state, so that the unmanned aerial vehicle battery loss is reduced.

In summary, the technical scheme provided by the embodiment has the following beneficial effects: 1. the emergency basic requirement of the unmanned aerial vehicle can be met, and the battery loss of the unmanned aerial vehicle can be reduced. Because the unmanned aerial vehicle battery electrically connected with the first type charging potential is kept in a higher SOC state for a long time, the unmanned aerial vehicle battery electrically connected with the first type charging potential can be used for supplying power to the unmanned aerial vehicle immediately when an emergency task exists. In addition, the unmanned aerial vehicle battery with the plurality of second type charging positions electrically connected can perform discharging treatment in a storage state under the condition that discharging conditions are met, and when an emergency task exists, the scheme can also realize fast charging of the unmanned aerial vehicle battery with the plurality of second type charging positions electrically connected. Therefore, the scheme not only meets the emergency basic requirement of the unmanned aerial vehicle, but also enables most unmanned aerial vehicle batteries to be stored in a proper SOC state, thereby being beneficial to reducing the battery loss of the unmanned aerial vehicle and improving the user experience. 2. According to different scenes of unmanned aerial vehicle application, two charging modes of fast charging and slow charging are provided, so that different charging requirements of users can be met, and the user experience is improved. For example, when the drone is applied in a scenario with emergency tasks, the user may select a fast charge mode to charge the drone battery to ensure that the upper battery can be used as soon as possible; when the unmanned aerial vehicle is applied to a scene without emergency tasks, a user can select a slow charging mode to charge the unmanned aerial vehicle battery.

In addition, in order to guarantee preferentially that can satisfy the emergent basic demand of unmanned aerial vehicle, the controller is after receiving the instruction of charging, will charge to the first type to charge the electric connection unmanned aerial vehicle battery of electric potential to the priority more than the default electric quantity. That is, the method provided in this embodiment further includes:

In addition, considering that in general, the higher the voltage of the unmanned aerial vehicle battery, the more the remaining power of the unmanned aerial vehicle battery is, the faster the unmanned aerial vehicle battery can reach the preset state of charge when being charged.
