Abstract
The invention provides an equalizing device for a vehicle soft-packed battery and an equalizing method for the soft-packed battery. According to the equalizing method for the vehicle soft-packed battery, a battery to be equalized is connected to a parallel equalization circuit by using an equalizing device for a vehicle soft-packed battery, battery cells to be equalized are sequentially equalized by adopting a first-in first-out sequence, and the SOC of each cell equalized is maintained within a preset range; and the number of the cells entering the equalizing device for the vehicle soft-packed battery is N, and the equalizing time of the battery cells is T. The equalizing device for the vehicle soft-packed battery comprises a holder clamping type or a copper sheet compressing type. On the premise of remarkably improving the equalizing efficiency of the battery cell, the invention can reduce the space and cost required by the equalizing operation, and ensure that the SOC difference of the equalized battery cell is maintained within a certain range, and it is a low-cost high-efficiency battery cell equalizing device. The invention is suitable for equalizing a large number of battery cells on a production line.
