Background technology
So-called super capacitor, its characteristic is except self-capacity is big, sizable electric energy temporarily can be stored, not only have an invertibity, and can do storage power and the action that releases energy at short notice, be a power density height, energy-accumulating element that energy density is low, more have a kind of novel hybrid super capacitor batteries to have function and the characteristic of battery concurrently in recent years; Compared to super capacitor, general energy-storage units can't bear the energy storage of the large current charge in the short time and the release of large-current electric energy, and power density is low, energy density is high, and both have their pluses and minuses separately.
Complementary characteristic between the two is familiar with by popular already, and both arrange in pairs or groups mutually technology of application are also arranged much on the market, and these correlation techniques can be divided haply and done two classes.The first kind is super capacitor and energy-storage units to be done the application of parallel (Parallel Mode), also be about to both complementary characteristics, do selection by a control unit, the operating position of looking is at that time got optimal powering mode, power with energy-storage units, or via super capacitor with the electric power of unstable electric power source do temporary after supply again, the most effective use (as motor miscellaneous) is done in the big electric current power supply of desire moment startup running or the conventional target of powering that turns round, reached the purpose of both advantages of applying in a flexible way when the time comes; Second class then is super capacitor and energy-storage units to be done the application of tandem formula (Cascade Mode); that is collect intermittent electric power source via super capacitor and come energy-storage units is charged; and energy-storage units is done the action of power supply again to load device; this moment, super capacitor was played the part of the role of auxiliary energy storage unit charging; the injury that can avoid intermittent electric power source that energy-storage units is directly caused, this function are a protection charging effect.
Yet, though more than two class application technologies have characteristic in innovation and the practicality concurrently, lose its comprehensive and development diversification, the real space that innovation is arranged and make a leapleap forward in the collocation technology of between and the design of application circuit.
Summary of the invention
In view of this; what purpose of the present invention namely provided a kind of super capacitor and energy-storage units discharges and recharges the keyholed back plate circuit; wherein the tandem formula of this super capacitor and energy-storage units charging keyholed back plate circuit has not only been accomplished the protection charge function of tandem pattern, and the selection of intelligent parallel operation function more is provided.A kind of super capacitor that the present invention designs and energy-storage units discharge and recharge the keyholed back plate circuit, it mainly includes at least one electric power source, at least one super capacitor, discharges and recharges keyholed back plate circuit, at least one energy-storage units; Wherein this discharges and recharges the keyholed back plate circuit and includes a control unit, at least one path switch unit, an energy-storage units state sensing circuit and a super capacitor state sensing circuit; And this path switch unit includes at least one common connection end, at least one charge path link, at least one discharge path link, and this control unit has the handoff functionality of protection charging and parallel operation simultaneously concurrently.In different embodiment, this super capacitor state sensing circuit and energy-storage units sensing circuit also can be arranged on of the present invention discharging and recharging outside the keyholed back plate circuit, are electrically connected to then and discharge and recharge the keyholed back plate circuit, do not limit at this.
This control unit that discharges and recharges in the keyholed back plate circuit can be according to the stored energy state of state, super capacitor or energy-storage units of electric power source power supply, and the variable condition of loading demand magnitude of current size, and then indication path switch unit is made corresponding Path selection.
First kind of Path selection is charging keyholed back plate mode switch function; this moment normality electric power source (as: civil power, generator for electricity generation) or intermittently unstable electric power source (as Brake car, descending, strong and weak unstable wind-force electric power source etc.) will be supplied electric energy to energy-storage units via super capacitor earlier again; that super capacitor is played the part of namely is the key player of complementary charging; and protect energy-storage units to avoid directly being injured by the electric energy of electric power source simultaneously, energy-storage units is supplied to load device with the electric energy that sends again subsequently.The electric current that discharges through super capacitor all has outstanding automatic corrective action for the electric wave in alternating current and the direct current, electricity frequency, electromagnetism, and the internal resistance that the energy-storage units (battery) that is recharged during the reply charging produces is lowered helpful, the carrying out of favourable charging.
Second kind of Path selection is discharge keyholed back plate mode switch function, selects respectively according to the magnitude of current size of loading demand.
Super capacitor directly give independent discharge-electric power source can be continuously the prerequisite of supply electric energy under, energy-storage units is the full charging energy, it is idle that super capacitor is unlikely to, and waste comes from the electric power that electric power source is supplied.
2. energy-storage units discharges separately-has stopped power supply or the not enough demand that continues offered load of super capacitor savings electric weight in electric power source, and the loading demand magnitude of current is less.
Super capacitor discharge separately-medium at the loading demand magnitude of current, but exceed energy-storage units separately during the deliverability of discharge, discharged separately by super capacitor.
4. parallel discharge-bigger at the loading demand magnitude of current needs set energy-storage units and super capacitor to pull together supply jointly when discharging.
The third Path selection is to recharge the keyholed back plate mode switch function, the electric energy instability or the electric power source that come from electric power source when super capacitor acceptance have been ended power supply, and the electric energy that stores in the super capacitor has been released into default lower limit, the role of super capacitor and energy-storage units will do exchange at this moment, become energy-storage units to the complementary charging of super capacitor, ensureing that super capacitor has an amount of electrical power storage at any time, in order to if super capacitor is supplied to load device with the electric energy that sends again when needing big electric current; And if when needing bigger electric current, super capacitor more comprises state in parallel with energy-storage units, and the common power supply when in order to the execution of awaiting orders heavy-current discharge demand more being arranged is discharged to the task of load device use.
Need to prove at this, in different embodiment, charging keyholed back plate mode switch function of the present invention with recharge the keyholed back plate mode switch function and can be arranged on simultaneously and discharge and recharge in the keyholed back plate circuit, switch when needed; Yet in different embodiment, discharge and recharge the keyholed back plate circuit and also can only comprise charging keyholed back plate mode switch function or recharge the keyholed back plate mode switch function, do not limit at this.
Because super capacitor is compared to general energy-storage units (battery), having the charging can finished fast reaches up to tens thousand of times even the characteristic of hundreds thousand of cycle lives, super capacitor, particularly many group super capacitors combination, via control unit timer and cut-off switch, can arrange the independent or branch component echelon of super capacitor, discharge successively, charge to energy-storage units, form constant voltage and current limiting pulse at intermittence point and put charging effect.Even can utilize and recharge keyholed back plate pattern control and be arranged to Reflex reverse pulse charge mode, reach better charging effect, shorten the charging interval, increase energy-storage units (battery) life-span.
Discharge and recharge the keyholed back plate circuit through like this design, make collocation between super capacitor and the energy-storage units become intelligence is more arranged, switching, buck, detection, the accent that can realize supplying electric energy output flow, unload management and control such as stream, voltage stabilizing, can not only effectively make super capacitor reach complementary purpose to the energy-storage units power supply, electric power source is to injury and the contradiction of energy-storage units in the time of more avoiding power supply really, really accomplished certain charging, effective multinomial function such as protection and parallel operation.
