## 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

### Claim 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;
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;
a warning unit configured to issue a warning when the non-contact power transmission is temporarily stopped in response to operation made to the operation portion; and
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 operation made to the operation unit, the warning unit stops issuing the warning, and the notification unit sends an electronic notification to the predetermined destination indicating that the non-contact power transmission is temporarily stopped due to operation made to the operation portion, and
wherein when the non-contact power transmission is resumed due to operation made to the operation portion, the notification unit sends an electronic notification to the predetermined destination indicating that the non-contact power transmission is resumed due to operation made to the operation portion.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 2)

The non-contact charging system according to claim 2, wherein
the informing unit is provided in the power transmission unit.
