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.
