The invention relates to a vehicle-mounted battery control method, a vehicle-mounted battery system and an electric vehicle. The method comprises the following steps: receiving a first voltage obtained by detecting a vehicle battery by a battery energy control module; judging whether the battery energy control module breaks down or not according to the first voltage; and when it is judged that the battery energy control module breaks down, the battery is controlled to quit the current working state, so that a secondary protection function of the battery is established on the basis of the battery energy control module, and the problem that the battery is overcharged or overdischarged due to the fact that the battery energy control module breaks down is solved.
本申请涉及一种车载电池控制方法、车载电池系统和电动汽车,通过接收电池能量控制模块检测车辆电池所得的第一电压;根据第一电压判断电池能量控制模块是否发生故障;在判断到电池能量控制模块发生故障的情况下,控制电池退出当前工作状态,如此,在电池能量控制模块的基础上建立了电池的二次保护功能,解决了因电池能量控制模块出现故障导致电池过充或者过放的问题。
