Abstract

The charging apparatus supplying power from a power source to a vehicle includes a body, a cable, a communication device, a starting switch and a controller. The controller is connected to the communication device and the starting switch for controlling the power supply from the power source to the charging connector. If the charging connector is connected to a vehicle which has no communication function for communicating with the charging apparatus, the controller controls so that a voltage is applied to the charging connector when the starting switch is operated. If the charging connector is connected to a vehicle which has communication function for communicating with the charging apparatus, the controller controls so that a voltage is applied to the charging connector in accordance with the communication between the communication device and the vehicle.

Claims

1. A charging apparatus supplying power from a power source to a vehicle, the charging apparatus comprising:

a body;

a cable, one end of which is fixed to the body and the other end of which has a standardized charging connector that is connectable to the vehicle;

a communication device for communicating charging information with the vehicle which has communication function for communicating with the charging apparatus;

a starting switch provided in the body for starting charging the vehicle; and

a controller connected to the communication device and the starting switch for controlling the power supply from the power source to the charging connector, wherein if the charging connector is connected to a vehicle which has no communication function for communicating with the charging apparatus, the controller controls so that a voltage is applied to the charging connector when the starting switch is operated, wherein if the charging connector is connected to a vehicle which has communication function for communicating with the charging apparatus, the controller controls so that a voltage is applied to the charging connector in accordance with the communication between the communication device and the vehicle.

2. The charging apparatus according to claim 1, further comprising a sensor for detecting that charging is being performed and transmitting a detection signal to the controller, wherein if the sensor does not detect that charging is being performed when a predetermined time has passed since the starting switch was operated, the controller controls so that no further voltage is applied to the charging connector.

3. The charging apparatus according to claim 1, further comprising a delay circuit provided in the controller in such a way that a voltage is applied to the charging connector when a predetermined time has passed since the starting switch was operated.

4. The charging apparatus according to claim 1, wherein the charging apparatus is a charging station for charging a storage battery of the vehicle, the charging station including a power source for supplying power.

5. The charging apparatus according to claim 1, further comprising:

a holder for holding the charging connector;

a detecting device for detecting removal of the charging connector from the holder; and

an indicator for indicating application of a voltage to the charging connector, wherein after the detecting device detects the removal of the charging connector from the holder, the indicator differently indicates whether or not a voltage is applied to the charging connector.

6. The charging apparatus according to claim 5, wherein the indicator is an indicator lamp, wherein when the charging connector is removed from the holder and no voltage is applied to the charging connector, the indicator lamp flickers, wherein when the charging connector is removed from the holder and a voltage is applied to the charging connector, the indicator lamp is illuminated.

7. The charging apparatus according to claim 5, wherein the detecting device is a user authentication device for authenticating a user.
