Has been. In particular, when a resonance phenomenon is used between the transmitting/receiving coils, it is referred to as a magnetic resonance method and a technical distinction is made from the magnetic induction method. When such a wireless charging system is applied to a vehicle, there is an advantage that the driver does not need to connect a cable directly to the battery while driving the vehicle.Therefore, a wireless charging device with a wireless charging system is installed in the vehicle to easily wirelessly connect the battery. It is charging.

On the other hand, the vehicle is equipped with a cup holder capable of storing beverage containers, and recently, a wireless charging device has been added to the cup holder so that the battery can be wirelessly charged while the portable device is stored in the cup holder. However, wireless charging The device generates heat during the process of generating power for charging between the transmitting coil unit installed in the cup holder and the receiving coil unit built in the portable device. This heat reduces the wireless charging efficiency and shortens the life of the device. There is a problem.
