摘　　要：由于串联电池组充电时的不均衡,导致电池循环寿命缩短,均衡充电成为了串联电池组充电技术中重要的考虑因素。为改善串联电池组充电时的不平衡,应保证电池组中所有电池的电压都处在同一水平状态。本文设计一种用单片机控制的双向无损均衡充、放电模块,并通过实验验证了该模块的效果。Due to the cycle life shortening of series-connected battery Strings suffered from the charge unbalance under charge/discharge operations, charge equalization becomes an important consideration of charging technology on series connected batteries. In order to achieve the state of charge equalization, the battery voltage difference between batteries after charging should be minimized as possible. This paper proposed a non-dissipative bi-direetional charge/discharge equalization module base on singlechip .The validity and effectiveness of this module is verified through experiments.
