锂离子电池组的均衡控制与设计

The design and Control of Ballancing Lithium Ion Battery

基于现有的锂离子电池制造水平,单体电池存在一定差异,为了避免个别单体的过充、过放所导致的电池组失效,使其性能接近单体电池的平均水平,应对电池组中各单体之间实现均衡控制,描述了电池的均衡控制方法、电路设计和实现步骤,并对锂离子电池进行均衡充电试验,结果表明该方法能有效的弥补电池的不一致性。

Based on lithium ion battery technology and difference bettwen cells. The battery cells should be balanced so as to make its capacity achive cells averge capacity and avoid battery failure come out of single cell＇s overcharging or, overdischarging. The process of balancing lithium battery has bean given in this paper.
