Device for recharging the batteries of an electric vehicle

摘要

The portable battery charger has a flat box that is placed on the ground under the vehicle, and connected to a standard mains outlet. The box is shaped so a handle is formed at one end. The box contains a high frequency generator that activates a coil which couples magnetically to a corresponding coil mounted on the underside of the vehicle. The user slides the unit into a guide built into the underside of the vehicle. When the unit is correctly positioned it operates a switch which initiates the inductive energy transfer. A light source (12) attached to the outside of the unit assists visibility while the unit is being put in place.
