It is. In particular, when the resonance is used between the transmitting and receiving coils, it is called a magnetic resonance method and a technical distinction is made between 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, the demand is increasing, mainly in luxury vehicles.

On the other hand, the vehicle is provided with a cup holder for storing a beverage container, etc. Recently, a wireless charging system is added to the cup holder to allow the battery to be wirelessly charged while storing the portable device in the cup holder.

However, the wireless charging system generates heat during the process of generating power for charging between the transmitting coil unit mounted on the cup holder and the receiving coil unit embedded in the mobile device, which degrades the wireless charging efficiency and the lifetime of the device. There is a problem of shortening.
