Abstract

A non-contact charging system includes: a power receiving unit mounted on a transportation device; a power transmission unit, installed on a flat surface, configured to transmit power to the power receiving unit in a non-contact manner; and a power supply unit configured to control power supply to the power transmission unit, the power supply unit including an operation portion configured to temporarily stop or resume non-contact power transmission from the power transmission unit to the power receiving unit.

Claims

1. A non-contact charging system comprising:

a power receiving unit mounted on a transportation device;

a power transmission unit, installed on a flat surface, configured to transmit power to the power receiving unit in a non-contact manner; and

a power supply unit configured to control power supply to the power transmission unit, the power supply unit including an operation portion configured to temporarily stop or resume non-contact power transmission from the power transmission unit to the power receiving unit.

2. The non-contact charging system according to claim 1, further comprising

an informing unit configured to inform visually about information indicating that the non-contact power transmission is in progress while the power transmission unit is performing the non-contact power transmission.

3. The non-contact charging system according to claim 1, further comprising

an informing unit configured to inform audibly about information indicating that the non-contact power transmission is in progress while the power transmission unit is performing the non-contact power transmission.

4. The non-contact charging system according to claim 2, wherein

the informing unit is provided in the power transmission unit.

5. The non-contact charging system according to claim 1, further comprising

a warning unit configured to issue a warning when the non-contact power transmission is temporarily stopped in response to an operation to the operation portion.

6. The non-contact charging system according to claim 5, further comprising

a notification unit configured to send an electronic notification to a predetermined destination corresponding to an owner of the transportation device, wherein

when a predetermined time elapses in a state where the non-contact power transmission is not resumed after the non-contact power transmission is temporarily stopped in response to the operation of the operation unit, the warning unit stops issuing the warning, and the notification unit sends an electronic notification indicating that the non-contact power transmission is temporarily stopped due to the operation of the operation portion to the predetermined destination.

7. The non-contact charging system according to claim 1, further comprising

a notification unit configured to send an electronic notification indicating that the non-contact power transmission is temporarily stopped or is resumed due to the operation of the operation portion to a predetermined destination corresponding to an owner of the transportation device.
