Abstract

一种电池异常检测装置(11),包括:电压突变检测电路(12),电压突变检测电路(12)用于检测电池电压是否发生突变,并在电池电压发生突变时输出突变信号;电流检测电路(14),电流检测电路(14)用于检测电池耗电流,并在电池耗电流小于预设电流阈值时输出低电流信号;异常检测单元(13),异常检测单元(13)在接收到突变信号和低电流信号时判断电池存在异常,并对电池存在异常的状态信息进行存储,以及将电池存在异常的状态信息发送给终端设备(200)的控制器(201)。所述电池异常检测装置(11)通过检测电池电压是否出现突变和检测电池耗电流大小来判断电池是否因受损而存在异常,避免因电池异常带来安全隐患。
