The invention relates to a control method of a vehicle power supply device and the vehicle power supply device. The method comprises the following steps: controlling the bidirectional voltage converter to work in a first operation mode, the relay module is controlled to switch on a first path between the bidirectional voltage converter and the motor controller to be powered, switch off a second path between the high-voltage battery module and the motor controller to be powered, and switch off a third path between the high-voltage battery module and the bidirectional voltage converter; the low-voltage battery module is used for supplying power to the motor controller to be powered; and under the condition of determining that the voltage of the input end of the motor controller meets the preset condition, controlling the relay module to turn off the first access and turn on the second access, so that the high-voltage battery module is adopted to supply power to the motor controller to be powered. The current impact on the motor controller during power supply is reduced, the safety of the motor controller is improved, and the motor controller is low in hardware cost, simple and convenient.

    本申请涉及一种车辆供电装置的控制方法、车辆供电装置。该方法包括:控制双向电压变换器以第一运行模式工作,并控制继电器模块导通双向电压变换器与待供电的电机控制器之间的第一通路、关断高压电池模块与待供电的电机控制器之间的第二通路、以及关断高压电池模块与双向电压变换器之间的第三通路,以采用低压电池模块为待供电的电机控制器进行供电;在确定电机控制器的输入端电压满足预设条件的情况下,控制继电器模块关断第一通路,导通第二通路,以采用高压电池模块为待供电的电机控制器进行供电。减小了电机控制器在供电时受到的电流冲击,提高了电机控制器的安全性,并且硬件成本低,简单方便。
