Abstract

In recent years, lithium-ion battery packs are more and more widely used in new energy vehicles. In order to improve the battery life of new energy vehicles and to solve the imbalance of lithium-ion battery packs during charging, according to different operating conditions of lithium ion batteries, The voltage and SOC relationship between the proposed battery balancing control strategy, and lithium battery balancing control system hardware and software circuit design, and then set up a lithium-ion battery pack balance control circuit experimental model, and the experimental verification, test The results show that the proposed balance control strategy for lithium-ion batteries has a significant improvement on the inconsistency of a single cell, and the theoretical estimates are in good agreement with the authenticity.
