Design of Li-Ion Batteries Equalization Module of Electric Vehicle


Article Preview

Due to the limited life of series-connected battery stack suffered from the imbalanced charging-discharging operation, the equalization management module has become the key part of a battery management system. To minimize the adverse effects caused by the performance inconsistency between individual battery cells, a battery equalization management module based on the super-capacitors was designed in this study. This module separated the imbalance status into three types, applied different control strategy according to the status, and balanced every sub-group respectively. Simulation and experimental results showed that not only the module made the battery pack charge and discharge balanced, but also the efficiency of equalization was improved.
