The invention provides a vehicle-mounted power supply method, device and equipment and a storage medium. The method comprises the steps of obtaining a connection confirmation signal and a power supply handshake signal collected by a vehicle-mounted bidirectional charger module, and a high-voltage power-on signal collected by a battery management module; and when it is judged that a preset vehicle-mounted power supply condition is met according to the connection confirmation signal, the power supply handshake signal and the high-voltage power-on signal, sending a power supply request signal to a battery management module so as to enable the battery management module to send a discharge enable signal to the vehicle-mounted bidirectional charger module after responding to the power supply request signal, and enabling the vehicle-mounted bidirectional charger module to invert the direct current of the power battery and output the direct current into alternating current. By adopting the embodiment of the invention, the direct current of the power battery can be directly inverted and output into the alternating current when the vehicle-mounted power supply request is generated, so that the output power of the vehicle-mounted power supply equipment is improved.

    本发明提供了一种车载供电方法、装置、设备及存储介质,该方法包括:获取车载双向充电机模块采集的连接确认信号和供电握手信号,以及电池管理模块采集的高压上电信号;在根据所述连接确认信号、所述供电握手信号和所述高压上电信号判断预设车载供电条件满足时,向电池管理模块发送供电请求信号,以使所述电池管理模块在响应所述供电请求信号后向所述车载双向充电机模块发送放电使能信号,并由所述车载双向充电机模块将动力电池的直流电逆变输出为交流电。采用本发明实施例,能够在发生车载供电请求时,将动力电池的直流电直接逆变输出为交流电,从而提高了车载供电设备的输出功率。
