The invention discloses a telescopic electric vehicle wireless charging device. The telescopic electric vehicle wireless charging device specifically can be divided into a charging side subsystem and a vehicle-mounted side subsystem. The charging side subsystem comprises a protective cover, a charging side primary coil, a driving mechanism, a power distribution control cabinet and a controller; the vehicle-mounted side subsystem comprises a vehicle-mounted power battery, a variable-current voltage stabilizer, a vehicle-mounted side secondary coil and a positioning camera. When an electric vehicle needs to be charged, a driver can park the vehicle in the optimal charging position with the assistance of the positioning camera; the controller controls the driving mechanism to work, the charging side primary coil is raised, the protective cover is mounted on the charging side primary coil, and under the assistance of a distance-measuring radar, the charging primary coil is fixed in a set position. The controller then controls the power distribution control cabinet to supply power for the charging side primary coil; according to the electromagnetic induction principle, the vehicle-mounted side secondary coil senses the electric energy of the charging side primary coil, and the electric energy is used for charging the vehicle-mounted power battery after passing through the variable-current voltage stabilizer. The telescopic electric vehicle wireless charging device is capable of greatly improving the wireless charging efficiency of the electric vehicle; the telescopic electric vehicle wireless charging device can be realized by virtue of modification in the existing park, and is easy to popularize.
