Further, described cell is lithium ion battery.
Referring to accompanying drawing 1,3 system Voltage-output power supply, output voltage is respectively 12V, 15V and 27V. According to 3 kinds of power supply bodiesOutput voltage processed, electric current and power-on time requirement, design battery pile scheme under every kind of system and cell scheme,Select cell that in 3 kinds of power supply systems, discharge current maximum, capacity are the highest as a reference, 12V, 15V system supply currentRelatively little, the time is relatively short, using 27V system power supply cell result of calculation as cell scheme.
In conjunction with cell platform, pile adopts 28 cells to bond with 4 × 7 closs packing forms, then uses cross-over connectionSheet spot welding connects into the connection status of 4 and 7 strings. Jumper leaves welding hole, and the wire on charging, power supply port is welded direct toOn welding hole, realize functions such as battery charging, monitoring and different system power supply outputs. B1-B7 is 27V system output pile,Connect by the positive negative wire of switch control; B1-B3 is 12V system output pile, shares output main track with 27V system, passes through switchControl main track is connected; B4-B7 is 15V output system pile, shares output negative wire with 27V system, connects by switch control negative wireLogical. In accompanying drawing 1: B is battery pack; B1-B7 is cell; K is output control switch; Out1 is the shared defeated of 27V and 15VGo out negative wire; Out2 is the shared output main track of 27V and 12V; Out3 is 15V output main track; Out4 is 12V output negative wire.
In the time that battery charging and discharging is safeguarded, directly export external charge equipment or discharge load between positive negative wire from 27V battery,All cells are carried out to charge and discharge maintenance simultaneously.
What more than enumerate is only specific embodiments of the invention. Obviously, the invention is not restricted to above embodiment, can also haveManyly similarly change shape. It is all that those of ordinary skill in the art can directly derive or associate from content disclosed by the inventionDistortion, all should think invention which is intended to be protected.
