A novel contactless inductive charging system with its proposed, and the equivalent models for the primary and secondary circuits induction. The parameter calculation formulae of the primary and secondary circuit topology for electric vehicles is are built based on the theory of mutual circuits are derived respectively for both single load and multi-load system, and the relationships between the power transmitted from system to load and circuit parameters are obtained. The charging power control circuit is designed and the intelligent charging control schemes with constant voltage and constant current are put forward. Pspice circuit model is adopted to conduct simulation on the system. The results of simulation verify the validity of theoretical analysis.
