Inductive charging for a vehicle
First Claim
1. A vehicle having a wireless power system, the vehicle comprising:
- a tractor and a trailer mounted to the tractor, the trailer having a refrigeration unit;
a first inductive charging pad mounted on the trailer, the first inductive charging pad electrically connected to a portion of the refrigeration unit; and
a second inductive charging pad mounted on the tractor, the second inductive charging pad electrically connected to a portion of the tractor and configured to induce an electrical current in the first inductive charging pad,wherein the first inductive charging pad and the second inductive charging pad are configured such that during relative rotation between the trailer and the tractor, the second charging pad can induce and maintain the electric current in the first inductive charging pad throughout a range of the relative rotation, andwherein the electrical current induced in the first inductive charging pad is employed to run the refrigeration unit.

Abstract
A vehicle having a wireless power system is provided. The vehicle includes a tractor and a trailer mounted to the tractor, the tractor having a tractor frame and the trailer having a refrigeration unit. A first inductive charging pad is mounted on the trailer, the first inductive charging pad electrically connected to a portion of the refrigeration unit. A second inductive charging pad is mounted on the tractor, the second inductive charging pad electrically connected to a portion of the tractor and configured to induce an electrical current in the first inductive charging pad. The first inductive charging pad and the second inductive charging pad are configured such that the second charging pad can induce and maintain the electric current in the first inductive charging pad throughout a range of relative rotation.
