Abstract
There is provided a power supply circuit, in which cost reduction is realized by reducing the number of electric wires. An inverterand a motorare supplied with power by a high-voltage battery. Relaystoare provided between the high-voltage batteryand the inverter. Both ends of each of relay coils C provided to the relaystoare connected to an ECU, and the ECUcontrols a current flowing through the relay coils C and thereby controls the turning on and off of the relaysto. A service plugis detachably provided between batteries making up the high-voltage battery, and when the service plugis detached, the supply of power from the high-voltage batteryto the inverterand the motoris blocked and when the service plugis attached, the supply of power from the high-voltage batteryto the inverterand the motoris enabled. An interlock switchis turned off when the service plugis detached, is turned on when the service plugis attached, and is connected between the ECUand the relay coils C.
