The invention provides a battery over-discharge prevention device and method and a vehicle, a first end of an electromagnetic induction coil of a first relay in the device is connected with an external power supply, a second end of the electromagnetic induction coil is connected with a first interface of a vehicle control unit, and a main contact of the first relay is a starting switch of a dormancy circuit of a vehicle-mounted battery; a first end of an electromagnetic induction coil of the second relay is connected with an external power supply, a second end of the electromagnetic induction coil of the second relay is connected with a second interface of the vehicle control unit, a main contact of the second relay is a turn-off switch of the vehicle electric appliance, and the vehicle control unit controls the grounding states of the first interface and the second interface to turn off the vehicle electric appliance. According to the method, the vehicle-mounted battery can be controlled to enter the dormant state, the current loop of the electric appliance is cut off, so that the electric appliance does not consume electricity any more, and the problem of feed of the vehicle-mounted battery caused by the fact that the vehicle-mounted battery still continuously discharges under the condition that the electric quantity is very low is fundamentally prevented.
本发明提供一种电池防过放装置、方法和车辆,装置中的第一继电器的电磁感应线圈的第一端与外部电源相连,电磁感应线圈的第二端与整车控制器的第一接口相连,第一继电器的主触点为车载电池的休眠电路的启动开关,第二继电器的电磁感应线圈的第一端与外部电源相连,第二继电器的电磁感应线圈的第二端与整车控制器的第二接口相连,第二继电器的主触点为车辆用电器的关断开关,整车控制器通过控制第一接口和第二接口的接地状态,可以控制车载电池进入休眠状态、切断用电器的电流回路,使得用电器不再进行耗电,从而从根本上防止了车载电池在电量很低的情况下仍继续放电,而造成的车载电池馈电的问题。
