ABSTRACT:
A transmission cable system that incorporates cooling channels that encircles electrical conductors with coolant. The transmission cable system also provides for breach or leak detection. More specifically, the transmission cable system maybe used with an inductive charging system that transfers electric power from a power source to batteries of an electric vehicle. The cable system includes a cooling system for storing, cooling, and pumping coolant, and a pressure sensitive switch for determining the pressure in the cooling system and for providing an output signal indicative of a drop in sensed pressure. A controller is coupled to the pressure sensitive switch that is responsive to the output signal from the switch for shutting down the inductive charging system in the event of a drop in sensed pressure. The transmission cable is electrically coupled between the power source and the electric vehicle for coupling electrical power to the batteries. The transmission cable is also coupled between the cooling system and the inductive charging system and includes a plurality of coolant channels that permit the flow of coolant between the cooling system and the inductive charging system that cools the transmission cable when transferring electrical power.
