Abstract

A non-contact power supply control unit supplies power in a non-contact manner from a power transmission coil to a power reception coil to charge a battery of a vehicle. A contact power supply unit is electrically connected via a cable to a connection terminal of the vehicle to supply power to its battery. A controller controls the non-contact power supply control unit and the contact power supply unit. When the battery of a first vehicle is being charged by one non-contact power supply system of the non-contact power supply control unit and the contact power supply system of the contact power supply unit, and there is a request from a second vehicle for a power supply by another power supply system, the power supply by one power supply system is continued and the power supply by the other power supply system is put on standby.

First claim

1 . A power supply device, characterized by comprising:
a non-contact power supply unit configured to charge a battery of a vehicle by supplying power from a power transmission coil to a power reception coil in a non-contact manner by at least a magnetic coupling; a contact power supply unit electrically connected to a connection terminal that is provided to a vehicle via a cable and supplies power to a battery of the vehicle; and a controller configured to control the non-contact power supply control unit and the contact power supply unit, the controller being provided to the power supply device, the controller being configured to continue a power supply by one power supply system and puts the power supply by the other power supply system on standby, when a battery of a first vehicle is being charged by one power supply system of either a non-contact power supply system by the non-contact power supply unit or a contact power supply system by the contact power supply unit, and there is a request for a power supply by the other power supply system from a second vehicle, and the controller being configured to transmit a signal for stopping the power supply by the non-contact power supply system to the first vehicle, and to charge the battery with the power that is inputted from the connection terminal, when a connector of the cable is connected to the connection terminal of the first vehicle during the charging of the battery of the first vehicle by the non-contact power supply system.

2 . (canceled)

3 . A non-contact power supply system provided with a vehicle comprising the power reception coil and a power supply device, the non-contact power supply system comprising
the power supply device comprising:
a non-contact power supply unit configured to charge a battery of a vehicle by supplying power from a power transmission coil to a power reception coil in a non-contact manner by at least a magnetic coupling;
a contact power supply unit electrically connected to a connection terminal that is provided to a vehicle via a cable and supplies power to a battery of the vehicle; and
a controller configured to control the non-contact power supply control unit and the contact power supply unit,
the vehicle comprising:
a communication unit being configured to transmit a request signal that requests a power supply to the power supply device by wireless communication;
a connection terminal configured to be electrically connected to the power supply device via a cable;
a battery configured to be charged by the power of the power reception coil and the power that is inputted from the connection terminal via the cable; and
a vehicle side controller configured to control the communication unit, and
the power supply device side controller being configured to continue a power supply by one power supply system and put the power supply by the other power supply system on standby, when a battery of a first vehicle is being charged by one power supply system of either a non-contact power supply system by the non-contact power supply unit or a contact power supply system by the contact power supply unit, and there is a request for a power supply by the other power supply system from a second vehicle, and the vehicle side controller being configured to transmit a signal for stopping the power supply by the non-contact power supply system, and to charge the battery with the power that is inputted from the connection terminal when detecting that a connector of the cable has been connected to the connection terminal during the charging of the battery by a non-contact power supply system based on the power from the power reception coil.

4 . A vehicle comprising:
a power reception coil configured to receive power in a non-contact manner from a power transmission coil that is provided to a power supply device by at least a magnetic coupling; a communication unit being configured to transmit a request signal that requests a power supply to the power supply device by wireless communication; a connection terminal configured to be electrically connected to the power supply device via a cable; a battery configured to be charged by the power of the power reception coil and the power that is inputted from the connection terminal via the cable; and a vehicle side controller configured to control the communication unit, the vehicle side controller being configured to continue the charging of the battery while in a state in which there is a request for a power supply from another vehicle to the power supply device during the charging of the battery and in which the power supply of the other vehicle is standing by, the vehicle side controller being configured to
continues the charging of the battery in a state in which the power supply of the other vehicle is standing by, when there is a request for a power supply from another vehicle to the power supply device during the charging of the battery, and
transmits a signal for stopping the power supply by the non-contact power supply system, and charges the battery with the power that is inputted from the connection terminal when detecting that a connector of the cable has been connected to the connection terminal during the charging of the battery by a non-contact power supply system based on the power from the power reception coil.
