A contactless recharging system and method for recharging a battery storage device onboard an electric vehicle has a primary converter station for converting power from a power source into high frequency power at a selected charging rate. The vehicle has a secondary converter for converting high frequency power into DC power to charge the battery. The converters are coupled together by a contactless coupling of a conductor loop and a coupling link forming a coaxial winding transformer. The coupled link and loop carry a communication indicating the selected charging rate of the battery. The link has a magnetic core and a core-mounted conductor at least partially surrounded by the core. The core-mounted conductor selectively at least partially surrounds a portion of the loop to transfer power therebetween. The core-mounted conductor is coupled to one of the converters, and the loop is coupled the other converter.
