Abstract
A contactless recharging system and method for recharging an energy storage device onboard an electric vehicle has a primary converter for converting power from a power source into high frequency power. A secondary converter on board the vehicle is coupled to the battery for converting high frequency power into charging power supplied to the energy storage device. The primary and secondary converters are coupled together by a contactless coupling of a conductor loop and a coupling link forming a coaxial winding transformer. The coupling link has a magnetic core and a core-mounted conductor at least partially surrounded by the magnetic core. The core-mounted conductor selectively at least partially surrounds a portion of the conductor loop to transfer power therebetween. The core-mounted conductor is coupled to either the primary or the secondary converter, with the conductor loop being mounted to the other of the primary and the secondary converters.
