Abstract

The imbalance of serially connected battery cells can easily lead to overcharge and over discharge, which can not only shorten the life of the battery pack but also reduce the energy efficiency. In this paper, aimed at the merit and demerit of existing measures, a new balancing method based on grouping and segmentation is proposed. By grouping the battery pack, the relationship between the effect of equilibrium and the number of balancing devices can be balanced, and the balancing current can be reduced. And then, the segmented balance is used to avoid the local balance in the group. The method is simulated and verified in this paper. For six series of 6V, 4.5Ah lead-acid batteries, this new measure can prolong discharge time of 24.7%, and reduce 44.9% of the monomer balancing current compared with the measure of using only one set of equalization device.
