A body of a power feed control device includes a housing recess to house a module including a holder, the first sub-bus bar, the second sub-bus bar, the third sub-bus bar, and a zero-phase-sequence current transformer. Lengths of respective extended pieces of the first sub-bus bar, the second sub-bus bar, and the third sub-bus bar are different from each other. The holder includes a rod portion, a post portion, and an extended portion. The extended portion covers the respective extended pieces of the first sub-bus bar, the second sub-bus bar, and the third sub-bus bar.

Power feed control device

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.

Power supply control device

The power supply control device in accordance with the present invention includes: a power reception terminal for receiving power; a power supply terminal for supplying power; a relay configured to make and break an electrical connection between the power reception terminal and the power supply terminal; a control circuit configured to control the relay; a power supply circuit configured to supply power to the control circuit by use of power received via the power reception terminal; and a printed wiring board. The control circuit and the power supply circuit are mounted on the printed wiring board.

A power feeding control apparatus includes a housing for accommodating at least a relay unit which opens and closes power feeding lines, a control circuit for controlling the relay unit, a leakage current detection circuit for detecting leakage current in the electric vehicle and a power supply circuit for generating a control electric power. The apparatus further includes a power source side connector and a vehicle side connector. The leakage current detection circuit includes a zero current transformer through which the power feeding lines extend and is configured to detect leakage current based on unbalanced currents flowing through the power feeding lines. Lead plates constitute a part of the power feeding lines and pass through a central opening of the zero current transformer, and the zero current transformer includes a positioning member molded within the central opening to fix the positions of the lead plates.

Power feeding control apparatus

A power feeding control device is provided with a main body accommodating an electric circuit for controlling power supply to a motor vehicle from a power source. First and second cables to be connected to the motor vehicle and the power source extend from the longitudinally opposite ends of the main body, respectively. The second cable includes a plug having a plug body accommodating a second contact electrically connected to a first contact provided in the main body, and a retaining ring attached to the plug body such that the retaining ring is rotatable about an axial direction of the plug body while being restricted to move in the axial direction. By screwing the retaining ring onto a thread portion of the main body, the retaining body is detachably attached to the main body in the state that the second contact is electrically connected to the first contact.
