Abstract

A wireless charging system for a vehicle includes a wireless power receiver receiving electric power wirelessly. A heat transfer device transferring heat generated from the wireless power receiver. A rechargeable battery is charged with the electric power received from the wireless power receiver and heated by receiving the heat that is transferred by the heat transfer device.

Claims

1. A wireless charging system for a vehicle, the wireless charging system comprising:

a wireless power receiver receiving electric power wirelessly;

a heat transfer device transferring heat generated from the wireless power receiver; and

a rechargeable battery being charged with the electric power received from the wireless power receiver and receiving the heat transferred by the heat transfer device.

2. The wireless charging system of claim 1, wherein the heat transfer device comprises a heat sink disposed to be in contact with the wireless power receiver and dissipating the heat generated from the wireless power receiver.

3. The wireless charging system of claim 1, wherein the heat transfer device comprises a fan generating airflow in a direction from the wireless power receiver to the rechargeable battery.

4. The wireless charging system of claim 1, wherein the rechargeable battery is an all solid battery.

5. The wireless charging system of claim 1, further comprising:

an electric heating coil disposed between the beat transfer device and the rechargeable battery.

6. The wireless charging system of claim 1, wherein the wireless power receiver receives the electric power induced by a magnetic field from a wireless power transmitter which is disposed on a ground surface of a battery charging station.

7. A wireless charging system for a vehicle, the wireless charging system comprising:

a wireless power receiver configured to receive electric power wirelessly;

a heat sink disposed to be in contact with the wireless power receiver and dissipating heat generated from the wireless power receiver;

a fan generating airflow in order to transfer the heat dissipated from the heat sink to air; and

an all solid battery being charged with the electric power received from the wireless power receiver and being heated by the heat transferred via the airflow that is generated by the fan.

8. The wireless charging system of claim 7, further comprising:

an electric heating coil disposed between the fan and the all solid battery.
