Abstract:
1. A computer implemented method of providing inductive energy to a battery charger assembly, the method comprising the steps of: at the battery charger assembly, a coil wirelessly receiving a polling message from an inductive source by listening for the source to alternate between an energized state and a de-energized state at regular intervals, the polling message being received while the battery charger assembly is in a polling listening mode; transmitting a request for power to the source responsive to receiving the polling message; receiving inductive power via the coil from the source responsive to the request, displaying an object on a graphical user interface indicative of the step of receiving for indicating a type of power being received; outputting a direct current powered by the received inductive power; and supplying the direct current to a separate battery pack, the battery pack being detachable from the battery charger assembly.
