Multi-mode Rechargeable Electric Vehicle

A rechargeable electric vehicle comprises a power rectifier to convert alternating current electrical energy to direct current electrical energy; a power inverter to convert direct current electrical energy to alternating current electrical energy; a rechargeable energy storage for storing direct current electrical energy; and a coil. In a first mode, alternating current electrical energy is received by the coil and passed through the power rectifier to form direct current electrical energy for storage in the rechargeable energy storage. In a second mode, direct current electrical energy is passed through the power inverter to form alternating current electrical energy and the alternating current electrical energy is passed through the coil for wireless transfer, over an air gap, to a secondary coil.
