摘要
提出了一种基于荷电状态的动力电池组均衡充电装置设计,该设计为每节电池配备一个充电模块。电池管理系统通过控制充电模块,实现动力电池组的均衡充电。通过分析各节电池的电压和充电时间,判断电池的荷电状态和电池性能,并根据荷电状态控制各电池的充电速率,从而提高电池组的性能和寿命。该充电装置采用模块化设计,扩展方便,便于应用在电动汽车行业。
This paper presents an equalization charging device based on state of charge for power battery pack. Each cell is equipped with a charging module in this device. Battery management device control the charging module in order to make an equalization charging for power battery pack. The state of charge and performance of battery are judged by analyzing the voltage and charging time of each battery,and the charging rate of each battery is controlled according to the state of charge,so as to improve the performance and life of the battery pack. The charging device is modular design,easy to expand and convenient for application in the electric vehicle industry.
