Abstract

A vehicle inductive power assembly and method for transferring electrical power inductively to an electrical device, in a motorized vehicle. The system includes an inductive power transfer system which is configured to provide the electrical power to the electrical device as well as a communications security system which is configured to establish a secure communications channel between the inductive power transfer system and the electrical device. Following activation of the inductive power transfer system, the communications security system initiates a handshaking procedure between the inductive power transfer system and the electrical device. If the handshaking procedure is successful the communications security system instructs the inductive power transfer system to commence providing the electrical power to the electrical device.
