This paper focuses on dynamic wireless power transfer for electric vehicles and proposes a vehicle-side control method for real-time power control and efficiency maximization. The proposed control strategy and controller design are presented based on a real-time estimation of the mutual inductance between a transmitter and a receiver. Simulations and experiments demonstrate that the proposed method can achieve the maximum efficiency and the desired power simultaneously. The transmitter and the

They are compensated by resonance capacitors for WPT via magnetic resonance coupling [9] , which can achieve a highly efficient mid-range transmission and robustness to misalignment. In this paper, a series-series (SS) compensated circuit topology is used and its circuit diagram is shown in Figure 2 [10]. The transmitter and the receiver are characterized by the inductances L 1 , L 2 , the series-resonance capacitances C 1 , C 2 , and the internal EVS29 International Battery, Hybrid and Fuel Cell Electric Vehicle Symposium
