The wireless charging circuit of electric vehicles , whose primary and secondary side mutual in-ductance coil are both series resonant inductive coupling , is deeply analyzed .And the relationship between the output power , the transmission efficiency and the circuit parameters is concluded when it is in the steady state . Moreover , the relationship is concluded between the voltages of the compensation capacitor corresponding to the mutual inductance coil , AC supply and battery and the mutual inductance by means of optimizing the electric ve -hicle battery voltage and AC supply voltage ratio .Furthermore , all the results are verified by simulation , which may lay a foundation for electric vehicles charging while the vehicle is moving .
