The invention provides an electric automobile wireless charging apparatus. The apparatus comprises an electromagnetic wave receiving coil, the electromagnetic wave receiving coil is connected with a storage battery through a rectification filtering circuit, the electromagnetic wave receiving coil is used for generating an alternating magnetic field so as to generate an induction electromotive force, an electric automobile is also provided with a wireless signal emission device, and the wireless signal emission device is connected with the storage battery through a voltage detection device; and only when the voltage detection device detects that the voltage of the output end of the storage battery is within a normal set scope, can the wireless emission device be activated, association signals are emitted, a wireless signal receiving end activates a control circuit after receiving the association signals, and the charging apparatus starts charging, such that open circuits, short circuits and over charge of the end of the storage battery are effectively avoided, and the system safety performance is improved.
