The invention belongs to the technical field of electric energy conversion application, and particularly provides a voltage conversion method of an electric vehicle battery inverter power supply, which comprises the following steps: when a battery module is detected to be connected with an inverter power supply module, detecting and acquiring the current available power quantity of the battery module through an electric quantity monitoring module; comparing the obtained available electricity quantity with a preset electricity quantity threshold value, and when the available electricity quantity is greater than the preset electricity quantity threshold value, sending a starting instruction to the inverter power supply module; when the inverter power supply module receives a starting instruction, the inverter power supply module is started, converts direct-current voltage of the battery module into alternating-current voltage and transmits the alternating-current voltage to the power supply master control module. When the power supply master control module receives the AC voltage, the power supply master control module supplies power to the corresponding circuit. Direct current of the battery module is converted into alternating current through the inverter power supply module, the alternating current is supplied to the power supply master control module, and electric energy is transmitted to a corresponding circuit through the power supply master control module, so that temporary electric power support is provided for household electricity utilization.

    本发明属于电能转换应用技术领域,具体提供了一种电动车电池逆变电源的电压转换方法,包括步骤:当检测到电池模块与逆变电源模块连接时,通过电量监测模块检测并获取电池模块当前的可用电量;根据所获取的可用电量与预设的电量阈值相比较,当可用电量大于预设的电量阈值时,向逆变电源模块发送启动指令;当逆变电源模块接收到启动指令时,启动并将电池模块的直流电压转化成交流电压传输至电源总控模块;当电源总控模块接收到交流电压时,向对应的电路供电。通过利用逆变电源模块将电池模块的直流电转换为交流电并供应到电源总控模块上,并通过电源总控模块将电能传输到对应的电路中,以此为家庭用电提供临时了电力支持。
