State identification of Evs' wireless power supplying based on inverter voltage detection

With the development of EVs' wireless power supplying technology, system security is becoming more and more important, and system state identification plays an important role in system security. Aimed at secondary side state identification of EVs' wireless supplying system, this paper proposes an identification method based on inverter voltage detection. Through analysis of inverter voltage values under different state, we know the contact of inverter voltage and power supplying state, so we can divide the system power supplying state according to the inverter voltage. The proposed method offers a reference for system controllability and security. Finally, the correctness of theoretical analysis is verified by experiment.
