ABSTRACT:
An oil cooled inductive coupler for use with an inductive charging system that charges propulsion batteries of an electric vehicle. The coupler is connected to a power source by way of a coaxial cable that has power conductors for coupling power to the coupler, and cooling channels for coupling high dielectric strength cooling fluid to and from the coupler. The coupler has a housing with a flood box formed therein having an open interior that forms a conductor termination area. The cooling channels are coupled to the flood box, and the power conductors are terminated in the termination area and are exposed to the cooling fluid that is pumped therethrough to cool them. A heat exchanger having a fluid flow path therethrough is coupled to the flood box and permits the cooling fluid to circulate therethrough. A primary winding is secured or bonded to the heat exchanger, a magnetic puck is disposed in an opening in the heat exchanger, and upper and lower primary winding covers enclose the heat exchanger. The cooling fluid is pumped through the coaxial cable, the flood box and the heat exchanger to cool the primary winding, the magnetic puck, and the power conductors, to permit high power levels to be transferred between the power source and the propulsion batteries of the electric vehicle.
