Abstract
The invention discloses a wireless charging authentication method. The wireless charging authentication method comprises the steps of: acquiring first identification information corresponding to vehicle-mounted equipment and second identification information corresponding to charging equipment; generating verification information according to the first identification information and the second identification information; and sending the verification information to a preset server for authenticating an electric vehicle according to the verification information by the preset server. The invention further discloses a wireless charging authentication device. When a user changes the charging equipment corresponding to one vehicle-mounted equipment, namely, the user changes a binding relationship between the first identification information and the second identification information, the verification information received by the preset server cannot match preset verification information, thus the preset server cannot complete the authentication of the electric vehicle, therefore, a wireless charging system can effectively identify whether the vehicle-mounted equipment of the electric vehicle and the charging equipment meet a preset binding relationship when authenticating the electric vehicle, and is more convenient in managing the electric vehicle.
