The invention discloses a signal processing method and device of a battery management system and a storage medium. The method can be used for monitoring the function safety of the battery management system, and comprises the following steps: monitoring the operation condition of a subsystem in the battery management system of a vehicle to obtain monitoring data; based on the monitoring data, determining that the battery management system is in a normal working state, and controlling the battery management system to verify a received battery fault signal to obtain a first verification result, the battery fault signal being obtained by monitoring the power battery by the vehicle; and in response to the fact that the first verification result is that the battery fault signal is valid, the fault state of the power battery is determined based on fault information in the battery fault signal, and the fault state is used for representing whether the power battery has a fault or not. The technical problem that the reliability of processing the battery fault signal by the battery management system is poor is solved.
本发明公开了一种电池管理系统的信号处理方法、装置以及存储介质。该方法可以用于对电池管理系统的功能安全进行监控,该方法包括:对车辆的电池管理系统中子系统的运行状况进行监控,得到监控数据;基于监控数据,确定电池管理系统处于正常工作状态,控制电池管理系统对接收到的电池故障信号进行校验,得到第一校验结果,其中,电池故障信号由车辆对动力电池进行监测得到;响应于第一校验结果为电池故障信号有效,基于电池故障信号中的故障信息,确定动力电池的故障状态,其中,故障状态用于表征动力电池是否出现故障。本发明解决了电池管理系统对电池故障信号进行处理的可靠性差的技术问题。
