Power supply control device for charging an electric vehicle

The power supply control device of the present invention includes: a set of power reception conductors; a set of power supply conductors; a set of intermediate conductors electrically connected to the set of power reception conductors, respectively; a set of relays configured to make and break electrical connections between the set of intermediate conductors and the set of power supply conductors, respectively; a zero-phase current transformer positioned to allow the set of intermediate conductors to pass through an inside of the zero-phase current transformer; a control circuit for controlling the set of relays responding to a detection result of the zero-phase current transformer; and a body block including a first block and a second block fixed to the first block. The set of power reception conductors and the set of power supply conductors are fixed to the first block. The set of intermediate conductors is fixed to the second block.
