摘要
电池组均衡作为电源管理系统的一项重要功能可以有效提高电池组的利用率,延长电池组的使用寿命。目前均衡方式有很多,对主流的均衡方法展开介绍,分析了各方法的控制复杂度和平均均衡电流,指出它们的优缺点,并就分析结果从控制复杂度、速度、成本、效率和体积五个方面对这些方法进行综合性评估,得出开关电容均衡是比较理想的均衡方式。
Balancing every battery is an important function of battery management system in the battery pack whichcould increase pack＇s usable energy and prolong its lifetime. Currently, there are many equalization methods forbattery packs. The popular equalization methods were introduced along with their advantages and disadvantages.The control complexity and average equalizing currents were calculated for the later comprehensive evaluation inaspects of cost, efficiency and volume referring to the results of other literature. The results imply that the switchedcapacitor is a relatively ideal equalizer.
