The invention discloses a power battery monitoring system and a vehicle. The power battery monitoring system comprises a power battery management system, the power battery management system comprises an acquisition board and a main control board, the main control board comprises a controller and a converter, the controller is connected with the converter, and the converter is connected with the acquisition board; the acquisition board is independently powered by the power battery, can continuously monitor the voltage and the temperature of the power battery, and feeds back a fault signal to the converter when the voltage and/or the temperature are/is abnormal; when the converter receives the fault signal, if the power battery management system is in a sleep mode, the converter is automatically awakened firstly, and then the controller is awakened to enter an operation mode, so that the controller executes a corresponding fault diagnosis action according to the fault signal. According to the invention, continuous safety monitoring of the power battery is realized in the sleep mode, the safety risk of the battery is reduced, a wake-up function does not need to be set, dark current consumed during working is very low, and additional hardware cost does not need to be increased.
本发明公开了一种动力电池监控系统及车辆。动力电池监控系统包括动力电池管理系统,动力电池管理系统包括采集板和主控板,主控板包括控制器和转换器,控制器与转换器连接,转换器与采集板连接;采集板由动力电池独立供电,能够持续监测动力电池的电压和温度,并在电压和/或温度异常时,反馈故障信号至转换器;转换器用于在接收到故障信号时,若动力电池管理系统处于休眠模式,则首先自动唤醒,进而唤醒控制器进入运行模式,以使控制器根据故障信号执行相应的故障诊断动作。本发明在休眠模式下实现了对动力电池的持续安全监控,降低了电池安全风险,也无需设置唤醒功能,在工作时消耗的暗电流很低,且不需要增加额外的硬件成本。
