| 中文摘要:锂离子电池组在新能源汽车中应用越来越广泛。为了提高新能源汽车的续航能力以及解决锂离子电池组在充电过程中存在不均衡的现象，根据锂离子电池不同工况下的电压与SOC关系，提出电池组的均衡控制策略，并对锂电池组均衡控制系统的软硬件电路进行了设计，进而搭建了锂离子电池组均衡控制电路实验模型，并进行了实验验证。实验结果显示，提出的锂电子电池均衡控制策略对单个电池的不一致性有明显的改善作用，并且理论估算值与真实性一致性较高。 |

| Abstract:Lithium-ion battery packs are 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. The experimental 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. |
