The embodiment of the invention discloses a power battery monitoring method. The method comprises the following steps: acquiring state conversion information of an electric vehicle through a battery management system; if the use state is switched to a stop state, converting the voltage of a power battery of the electric vehicle into target voltage through a device with a voltage conversion function; and after the lead-acid storage battery is powered off, using the target voltage to supply power to the battery management system so as to monitor the power battery in a stop state. The monitoring on the power battery is ensured. The invention further provides a power battery monitoring system and an electric vehicle.

    本申请实施例公开了一种动力电池的监控方法,包括:通过电池管理系统,获取电动汽车的状态转换信息;若所述使用状态切换为停止状态,通过具有电压转换功能的装置,将所述电动汽车的动力电池的电压转换为目标电压;在所述铅酸蓄电池下电后,利用所述目标电压,对所述电池管理系统进行供电,以便在停止状态对所述动力电池进行监控。保证了对所述动力电池的监控。本申请还提供了一种动力电池监控系统和一种电动汽车。
