Description
Technical field
The present invention relates to a kind of loose joint battery pack, loose joint battery pack charging device and charging methods.
Background technique
Currently, electric vehicle is widely available, it is convenient to bring to people's lives.Battery core is series connection inside battery of electric vehicle group
Structure passes through conducting wire between each battery core and welds.For a long time after (1 year to 2 years) use, because series circuit current is equal, voltage
With battery core quantity difference without equal (battery core quantity is more, and series circuit voltage is higher), series circuit is closer to battery plus-negative plate end
Voltage it is higher, and the higher physical injury to positive and negative extreme battery core of voltage is bigger, old battery pack be it is irremovable, always
Physical injury is generated to the battery core at series circuit both ends, the speed for resulting in the electric core aging is other battery cores in series circuit
Three to five times, once the decline of cliff of displacement formula will be presented in the performance of battery core decompression battery pack, voltage decline must replace very much electricity fastly
Pond group, but positive and negative extreme battery core decompression is removed, and other battery cores still can normally guarantee, if the battery core of replacement electrode tip, battery core
Resistance value it is again different, cause charging uneven, that is, the big battery core of resistance value is not fully filled, the small generation of resistance value overcharges existing
As, it is therefore desirable to it uses equalizing circuit (balancing disk), so makes battery pack increased costs.
Summary of the invention
The present invention is the knack above problem of the existing technology, provides a kind of loose joint battery pack, the charging of loose joint battery pack
Device and charging method.It can solve the problems, such as that the positive and negative extreme electric core aging of battery pack is too fast, not use equalizing circuit, can be improved
The recycling number of battery reduces the production cost of battery pack close to theoretical circulation number.
The technical solution of the invention is as follows:
A kind of loose joint battery pack, including multiple battery cores and power supply export positive and negative terminal, are characterized in that: further include:

Power switch is arranged on the conducting wire three being connected with power supply output plus terminal；
Power supply output positive and negative terminal, power switch, conducting wire three, each circuit plug, conducting wire two, each battery core and conducting wire one are constituted back
Road；
The circuit plug one and circuit plug two are male and female banjo；
Number label is respectively equipped in each battery core.
Further, the circuit plug one and circuit plug two are separately positioned on disk one and disk two and circumferentially
Direction is uniformly distributed.
Loose joint battery pack charging device, including charging circuit board, are characterized in that, the charging circuit board is by multiple
The charhing unit being connected between power input positive and negative terminal is constituted, and setting is exported with each charhing unit on charging circuit board
The battery core attaching plug one of the circuit plug three of end connection, the circuit plug three and loose joint battery pack is male and female banjo.
Further, the circuit plug three is along the circumferential direction uniformly distributed, and corresponds each other.
Further, the circuit plug three is arranged on disk three, and the disk three is arranged on charging circuit board.
Loose joint method for charging battery pack, including loose joint battery pack as described above and loose joint battery pack charging device, it is special
Different place is:
1, disconnecting power switch, by each circuit plug one respectively with the circuit plug three-phase interfix of battery pack charging device
It connects；
2, each battery core circuit plug one is transferred to after being full of, and is inserted according to number order with corresponding loose joint battery circuit
First two head and the tail successively grafting, until sticking with；
3, when loose joint battery pack use to power shortage, step 1 is repeated；
4, each battery core circuit plug one is transferred to after being full of, and according to number displacement sequence and corresponding loose joint battery pack electricity
Two head and the tail successively grafting of road plug, until sticking with；
5, it repeats Step 3: step 4 finally makes each battery core performance reach balanced until forming cyclic shift grafting.
Further, number order described in step 2 refers to " A.B.C.D.E ... ... P ".
Further, number order described in step 4 refers to " B.C.D.E ... ... P.A ".
The beneficial effects of the present invention are:
1, replaceable battery core reduces physical injury of the battery set electrode end to battery core in the position of battery pack, and injury is flat
It assigns to other battery cores, keeps electric core aging speed consistent, reinforce the consistency of battery core, improve cycle life to theoretical circulation
Number.Independent battery core individually charges, and because of the series connection that loose joint battery pack is plug-in, when charging can use 220 volt of 4 peace charging panel
Independent battery core to be inserted and is even charged, how many charging panel just used, the charging modes for doing " customization " formula to battery core are equivalent to for how many battery core,
Charging process is not by the resistance value influences of battery core.When battery core capacity is identical, can new and old battery core simultaneously use with, it is old according to Ohm's law
Battery core resistance value is big, and charging current is small, only will affect the charging time, but can all be full of；New and old battery core being used with and not using
Weighing apparatus charging circuit can reduce the use cost of battery pack, can extend the service life of battery pack, avoid because of Individual cells battery
Performance is bad, replaces with regard to whole group, saves a large amount of manpowers, financial resources.
2, charger is generally applicable, as long as same battery core (voltage is consistent) is all generally applicable.Battery core can intuitively be observed
State rejects expansion or the biggish battery core of internal resistance value in time, will not cause to overcharge phenomenon to battery core, it is ensured that when battery pack uses more
Securely and reliably.
