The invention relates to a vehicle-mounted power supply device, a vehicle and a vehicle power shortage starting system and method. The vehicle controller is electrically connected with the storage battery and used for detecting the voltage value of the storage battery and judging whether the storage battery is in a power-lack state or not according to the detected voltage value; the vehicle interface is arranged on a vehicle so as to realize electrical connection between the vehicle-mounted charger and external charging equipment; the input end of the vehicle-mounted charger is connected with the vehicle interface; the input end of the direct-current converter is connected with the output end of the vehicle-mounted charger, and the output end of the direct-current converter is connected with the storage battery; when the vehicle controller detects that the external charging device is connected with the vehicle and the storage battery is in a power-lack state, the external charging device is allowed to charge the storage battery through the vehicle-mounted charger and the direct-current converter. The problem that the vehicle cannot be started due to the fact that the storage battery is lack of electricity is solved.
本发明涉及一种车载供电装置、车辆、车辆亏电启动系统及方法,包括:蓄电池;车辆控制器,与蓄电池电性连接,用于检测蓄电池的电压值,根据检测到的电压值判断蓄电池是否处于亏电状态;车辆接口,设置于车辆,以实现车载充电机与外部充电设备的电性连接;车载充电机,其输入端与车辆接口连接;直流变换器,其输入端与车载充电机的输出端连接,直流变换器的输出端与蓄电池连接;车辆控制器检测到外部充电设备与车辆连接且蓄电池处于亏电状态,允许外部充电设备通过车载充电机和直流变换器为蓄电池充电。本发明解决了车辆因蓄电池亏电导致车辆无法启动的问题。
