Free QuoteTherefore, the proposed active equalization strategy also has superior efficiency in real application. To our knowledge, this is the first work to achieve series-connected battery pack active equalization by fusion of data-driven residual capacity online estimation and global optimization-based equalization current calculation.
Active equalization was better than passive equalization in reducing battery capacity differences. The maximum difference in state of charges among batteries with active equalization at a current rate of 0.25 C decreased from 10% to 9.207% in discharging, while that with passive equalization dropped from 10% to 9.492%.
Limited by the “weakest cell”, the maximum available capacity of battery pack without equalization in Case 1 and Case 2 are only about 642mAh and 588mAh, respectively. With the designed equalization strategy, the maximum available capacity of battery pack in those two cases can be further improved 10.29% and 10.25%, respectively.
Battery Equalization System As an energy management system, a battery equalization system [22, 23, 24, 25, 26] aims to reduce the energy differences among a battery pack's cells, thereby improving the pack's consistency. Equalization strategies and topologies are both part of battery equalization systems.
Common equalization strategies include the average comparison method and the fuzzy control method [29, 30]. Since most equalization strategies are quite difficult to use at present and many of them are in the experimental and verification stages, this review mainly discusses battery equalization topologies.
