Wheel assembly with inductive charging for vehicle using regenerative braking
First Claim
1. A method of charging an electrical storage unit for an electric vehicle, the method comprising:
- receiving, at a charge storage device within a wheel assembly of the electric vehicle, an induced charge resulting from one or more coil windings passing through a magnetic field created by a current flowing in at least one power transmission line;
receiving an indication to reduce a velocity of the electric vehicle;
based on the received indication, increasing a charging capacity of the charge storage device by coupling a plurality of capacitors to the one or more coil windings; and
transferring the charge stored in the charge storage device to the electrical storage unit of the electric vehicle via a rim of a wheel assembly.

Abstract
Systems, methods, and devices are described with respect to storing energy in an electric vehicle. At least one coil winding located in a wheel assembly is provided, where the wheel assembly includes a tire and a rim. At least one charge storage device located in the wheel assembly is provided. At least one electrical storage unit located within the electric vehicle is provided, where an induced charge resulting from the at least one winding passing through an electromagnetic field is stored in the at least one charge storage device and transferred to the at least one electrical storage unit via the rim of the wheel assembly. Moreover, a charging capacity for the at least one charge storage device may change to cause the electric vehicle to slow.
