The invention provides a control method and device for a commercial vehicle power supply, and belongs to the technical field of new energy automobiles, and the method comprises the steps: obtaining a power utilization demand of a socket load sent by a terminal, obtaining a socket load power utilization control instruction based on the power utilization demand of the socket load, and controlling a voltage reduction module based on the socket load power utilization control instruction, and the control module is used for reducing the high voltage of the power supply to the voltage required by the socket load, controlling the DCAC module based on the power utilization control instruction of the socket load, converting the direct current of the voltage of the socket load after voltage reduction to the alternating current, and performing power supply output for the socket load when the DCAC module is connected with the socket load. The technical problem that in the prior art, cost is high when a commercial vehicle multiplexes a DCAC module to achieve 220V AC power taking is solved.

    本发明提供了一种商用车电源的控制方法及装置,属于新能源汽车技术领域,其方法包括:获取终端发送的插座负载的用电需求,基于所述插座负载的用电需求,得到插座负载用电控制指令,基于所述插座负载用电控制指令控制降压模块,将电源的高压电降低为插座负载所需的电压,基于所述插座负载用电控制指令控制DCAC模块,将降压后的插座负载电压的直流电转换为交流电,并在所述DCAC模块与所述插座负载接通时为所述插座负载进行供电输出。本发明解决现有技术中存在商用车复用DCAC模块实现220V AC取电成本高的技术问题。
