锂离子电池管理系统研究

Study on lithium-ion battery management system

电动汽车最需要解决的问题之一是锂离子电池管理的问题。针对锂离子电池在充放电过程中出现的过充电、过放电以及锂离子电池组在串联使用过程中出现单体锂离子电池电压不一致的现象,设计了锂离子电池管理系统,能够对锂离子电池过充电、过放电进行保护,并均衡单体锂离子电池电压。

One of the most important problems for the electric vehicles is the battery management. Because the battery charging and discharging would cause phenomena, such as the unbalanced voltage, overcharge and overdischarge. In this paper, a lithium-ion battery management system was designed to control the circuit on and off,which could easily protect the Li-ion battery＇s overcharge and overdischarge, and balance voltage.
