The embodiment of the invention discloses vehicle equipment for detecting the state of a battery. The vehicle equipment comprises a controller, a load unit and a switch unit. The load unit is coupled to the battery, and the switch unit is coupled between the battery and the load unit. The controller may control the switching unit to disconnect or connect the battery and the load unit at a predefined frequency. The controller can switch the load unit, generate ripple voltage on the battery, measure the ripple voltage of each battery cell, and determine the abnormal state of the battery according to the ripple voltage of each battery cell. According to the embodiment of the invention, the state of the battery can be monitored and detected, good battery performance can be ensured, the service life of the battery is prolonged, and the safety of the vehicle is improved.
本申请实施例公开一种用于检测电池状态的车辆设备,包括控制器、负载单元和开关单元。负载单元耦合于电池,开关单元耦合于电池和负载单元之间。控制器可以控制开关单元以预定义的频率断开或连接电池和负载单元。控制器可以切换负载单元,在电池上产生纹波电压,并测量每个电芯的纹波电压,根据每个电芯的纹波电压确定电池的异常状态。本申请的实施例可以监控和检测电池的状态,可以确保良好的电池性能和延长电池寿命,提升车辆的安全性。
