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.

A contactless charging system for charging batteries on board plural electrical loads each having conductor loop and a secondary converter coupled thereto for converting AC power into DC power to charge the battery at a selected charging rate, the system comprising: a coupling link having a magnetic core and a core-mounted conductor at least partially surrounded by the magnetic core, the core-mounted conductor contoured for selectively at least partially surrounding a load loop, wherein the link is openable to receive, and closable to substantially surround, said load loop; and a primary converter coupled to the core-mounted conductor for converting power from a power source into the AC power at the selected charging rate corresponding to a load when coupled thereto by the link. A coupling link, comprising: a core-mounted conductor for surrounding a portion of a conductor loop coupled to a power source or a load, the core-mounted conductor for coupling to the other of the power source or the load; a magnetic core at least partially surrounding the core-mounted conductor; and a cooling fluid chamber defining a passageway for circulating a cooling fluid through the link in a direction substantially parallel with a direction of current flow through the core-mounted conductor, wherein the link is openable to receive the loop and closable to substantially surround the loop.
