The embodiment of the invention provides a battery cell management chip, a battery system and a vehicle. The chip comprises an acquisition circuit, a processing circuit and a control circuit, wherein the acquisition circuit is used for acquiring parameter values of working parameters of single battery cells and transmitting the parameter values to the processing circuit; the power supply supplies power to the processing circuit, the storage circuit is used for storing dynamic protection thresholds for working parameters, the processing circuit is used for adjusting the working states of the single cells under abnormal conditions, and the dynamic protection circuit is used for adjusting the working states of the single cells according to the dynamic protection thresholds. According to the invention, the working state of one single cell is monitored through one chip, so that the risk of state information loss of multiple strings of batteries caused by failure of one single cell is reduced; the working state of the battery cell can be dynamically standardized through the dynamic protection circuit, and high-efficiency use and battery protection are realized, so that the service life of the battery is prolonged.

    本发明实施例提供了一种电芯管理芯片、电池系统、车辆,该芯片包括:采集电路用于采集单体电芯的工作参数的参数值并传输至处理电路;电源为处理电路供电,存储电路用于存储针对工作参数的动态保护阈值,处理电路用于在异常情况下调整单体电芯的工作状态,动态保护电路用于按照动态保护阈值调整单体电芯的工作状态。本发明通过一个芯片监测一个单体电芯的工作状态,降低了一个单体电芯失效造成多串电池状态信息丢失的风险;可以通过动态保护电路动态规范电芯的工作状态,实现高效率使用和保护电池,从而延长电池的使用寿命。
