1. A contactless charging system for charging an energy storage device, comprising:

  • a primary converter for converting power from a power source into high frequency power;

    a secondary converter coupled to the energy storage device for converting high frequency power into charging power to charge the energy storage device;

    a conductor loop coupled to one of the primary converter and the secondary converter; and

    a coupling link having a magnetic core and a core-mounted conductor at least partially surrounded by the magnetic core, the core-mounted conductor coupled to the other of the primary converter and the secondary converter, the core-mounted conductor for selectively at least partially surrounding a portion of the conductor loop to transfer power therebetween.
