The invention relates to a power supply circuit of an electrified vehicle. A power supply circuit of an electrified vehicle according to the present disclosure is mounted on the electrified vehicle including: a battery configured to receive an electric power from an external DC power supply; an accessory configured to operate at a system voltage of the battery; and a DC inlet to which a voltage higher than the system voltage is applied from the external DC power supply. The power supply circuit includes a first power line, a step-down converter and a second power line. The first power line is configured to connect the DC inlet and the battery. The step-down converter is disposed on the first power line and configured to lower a voltage supplied to the battery from the DC inlet. The second power line has one end connected to the first power line between the step-down converter and the battery, and another end connected to the accessory.
本发明涉及电动车辆的电源电路。根据本发明的电动车辆的电源电路安装在电动车辆上,该电动车辆包括:电池,其被配置为从外部DC电源接收电力;附件,其被配置为以电池的系统电压操作;以及,DC入口,从外部DC电源向其施加高于系统电压的电压。电源电路包括第一电力线、降压转换器和第二电力线。第一电力线被配置为连接DC入口和电池。降压转换器被布置在第一电力线上,并且被配置为降低从DC入口向电池供应的电压。第二电力线的一端在降压转换器与电池之间连接到第一电力线,并且另一端连接到附件。
