This study presents the experimental study and analysis of double‐LCL resonant compensation network based wireless power transfer (WPT) system for electric vehicles. The WPT system could accomplish both constant current and the unity‐power‐factor for the transmitting terminal and the receiving terminal. In addition, the transmitting terminal inverter can achieve zero‐voltage‐switching. The multi‐physical characteristics of the transmitting and receiving terminals based on LCL resonant compensation network are analysed in detail. Finally, three‐dimensional finite element analysis and an experimental system with circular pads is setup to verify the theoretical analysis under different loads and horizontal/vertical misalignment conditions. At the condition of 200 mm gap and no horizontal misalignment, the system can supply the maximum output power of about 7.36 kW having the maximum efficiency of 95.87%.
