摘　　要：锂电池的能量密度越来越大,大能量密度的电池如果未能进行电流过大保护和温度过高的保护,不但有可能会损毁电池,还有可能造成电池起火等严重后果。当前的锂电池保护芯片既不能自动记录电池使用信息,价格又相对都比较昂贵。介绍了一种利用常见运算放大器及ARM单片机配合外围电路完成锂电池保护和信息记录、查询等功能的实现方法。The energy density of lithium battery is getting higher and higher.If the battery with high energy density fails to protect the battery with high current and high temperature,it may not only damage the battery,but also cause serious consequences such as battery fire.Current lithium-ion battery protection chips can not automatically record battery usage information,and are relatively expensive.This paper introduces a method to realize the functions of lithium battery protection,information record and query by using common operational amplifier and ARM single chip microcomputer and peripheral circuit.

关 键 词：智能锂电池 过流保护 高温保护 自动校准
