Abstract

An electric power is fed from a wireless feeding device to a feeding device, and the feeding device feeds the electric power to an object to which the electric power is fed. The feeding device includes a power receiving module, a power circuit and a controller. The power receiving module receives the electric power from the wireless feeding device. The electric power is fed from the power receiving module or from an AC adapter to the power circuit and the power circuit feeds the electric power to the object to which the electric power is fed. The controller interrupts a supply of the electric power from the AC adapter.

Claims

1. A feeding device to which an electric power is fed from a wireless feeding device and which feeds the electric power to an object to which the electric power is fed, the feeding device comprising:

a power receiving module that receives the electric power from the wireless feeding device;

a power circuit (i) to which the electric power is fed from the power receiving module or from an AC adapter and (ii) which feeds the electric power to the object to which the electric power is fed; and

a controller that interrupts a supply of the electric power from the AC adapter.

2. The feeding device according to claim 1,

wherein, when the controller determines that the wireless feeding device is connected and further when the controller determines that the AC adapter is not connected, the controller controls the electric power to be fed from the wireless feeding device.

3. The feeding device according to claim 1,

wherein, when the controller determines that the wireless feeding device is connected and further when the controller determines that the AC adapter is connected, the controller controls the electric power to be fed from the wireless feeding device based on a decision of a remaining quantity of a battery.

4. The feeding device according to claim 3,

wherein, when the controller determines that the remaining quantity of the battery is normal or more than normal, the controller stops to supply the electric power from the wireless feeding device, and

wherein, when the controller determines that the remaining quantity of the battery is lower than normal, the controller continues to supply the electric power from the wireless feeding device.

5. The feeding device according to claim 1,

wherein, when the controller determines that the wireless feeding device is not connected and further when the controller determines that the AC adapter is connected, the controller starts the supply of the electric power from the AC adapter, and

wherein, when the controller determines that the wireless feeding device is not connected and further when the controller determines that the AC adapter is not connected, the controller starts the supply of the electric power from a battery when the controller determines that a remaining quantity of the battery is normal or more.

6. The feeding device according to claim 5,

wherein the controller determines that the remaining quantity of the battery is lower than normal, the controller restrains the object to which the electric power is fed from being activated.
