In-Wheel Motor (IWM) which is a driving system of Electric Vehicles (EVs) is effective for expanding driving range and reducing vehicle weight. However, IWM has not been put in practical use because of a possibility of power lines disconnection. Therefore, we have proposed Wireless In-Wheel Motor (W-IWM) in which Wireless Power Transfer (WPT) is used to remove these lines and to enhance practicability of IWM. Moreover, we have proposed the advanced system of W-IWM which has Lithium-ion Capacitor (LiC) and circuit on its wheel side for dynamic charging. In this paper, a State of Charge (SOC) control of LiC on the wheel side in the advanced system is proposed. By applying the proposed control, the SOC control of the LiC and power management on the wheel side are achieved simultaneously. The proposed control is verified by simulations and experiments.
