ABSTRACT
In this study, it was attempted to prevent a problem when wireless charger is mounted on a vehicle. The problem is a decrease of charging efficiency. Generally it uses 3coils method to optimize the transmission/reception position for charging. But the problem occurs when there is a fine shaking during driving. Because it’s difficult to optimize the charging efficiency, we developed an auto focusing algorithm and thermal conductivity composite. We replaced the coil support body with the thermal conductivity material considering its efficiency.
