Claim 0:
1. A transportable unit for providing a self-contained inductive battery charger for charging an electric vehicle which comprises:
a moveable docking pad transportable to an off-grid location with an access ramp for parking the electric vehicle on the docking pad;
a source of renewable energy incorporated with the docking pad;
a storage battery located with the docking pad and connected with the source of renewable energy for receiving electricity therefrom;
a primary induction coil affixed to the docking pad, wherein the primary induction coil is connected with the source of renewable energy via the storage battery to receive an electric current therefrom for generating an alternating electromagnetic field;
an inverter connected between the storage battery and the primary induction coil for converting a d.c. current from the storage battery into an a.c. current for use by the primary induction coil to generate an alternating electromagnetic field;
a current control unit in the inverter for varying the frequency of the a.c. current from the inverter to control the alternating electromagnetic field; and
a secondary induction coil affixed to the electric vehicle in contact with the battery of the electric vehicle wherein, with the electric vehicle properly positioned and parked on the docking pad the electromagnetic field of the primary induction coil is positioned to establish a resonant inductive coupling with the secondary induction coil for recharging the battery of the electric vehicle.
