Charging devices within wheel portions
First Claim
1. A method of charging an electrical storage unit of 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 an electromagnetic field created by at least one power transmission line;
measuring a strength of the electromagnetic field created by the at least one power transmission line with one or more electromagnetic field detectors while the electric vehicle is moving at a velocity greater than a first threshold;
only storing the induced charge in the charge storage device when the electric vehicle is moving at the velocity greater than the first threshold and when the strength of the electromagnetic field is greater than a second threshold; 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.

9. A system for storing energy in an electric vehicle, the system comprising:
-
at least one coil winding located in a wheel assembly, the wheel assembly including a tire and a rim; at least one charge storage device located in the wheel assembly; one or more electromagnetic field detectors configured to measure a strength of an electromagnetic field created by at least one power transmission line while the electric vehicle is moving; and at least one electrical storage unit located within the electric vehicle, wherein an induced charge resulting from the at least one coil winding passing through the electromagnetic field created by the at least one power transmission line is stored in the at least one charge storage device only when the electric vehicle is moving at a velocity greater than a first threshold and when the strength of the electromagnetic field is greater than a second threshold, and wherein charge stored in the at least one charge storage device is transferred to the at least one electrical storage unit via the rim of the wheel assembly. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
