Description
Technical field
The present invention relates to battery technology field, more particularly, to series connection or the battery pack and battery of connection in series-parallel mixed marshalling
Group grouping method.
Background technology
Conventional batteries are in marshalling, the battery pack of either connect marshalling or connection in series-parallel mixed marshalling, to subtract as far as possible
Influence of the inconsistency to battery life between baby battery, manufacturer all suggest with same brand, same model, same batch, appearance
Measure the marshalling of identical battery to use, that is, the battery after organizing into groups in whole battery pack corresponding to unit voltage（Group）Capacity is all identical
's.And conventional batteries only provide the power supply that one group of supply voltage is battery voltage and outwardly powered after marshalling.
One of the characteristics of voltage height is battery pack, in some application scenarios, the voltage of the power battery pack of such as electric automobile is high
Up to 400 volts.It is responsible for the whole system of power supply in battery pack, the electrical equipment for often there are different rated voltages, on electric automobile
The motor of dynamical system and the rated voltage of electric machine controller in several hectovolts, and the auxiliary electronic equipment on periphery such as instrument/big
The specified electricity of lamp/steering indicating light/loudspeaker/ECU/ air-conditionings/power windows/skylight/rain brush/power assistance pump for steering/ABS/ air bags etc.
