1. An inductive battery charging system, comprising:

  • an inductive power apparatus that provides power to a target load when the inductive power apparatus is coupled to an alternating current power source;

    an observation circuit to determine a power consumption associated with the target load;

    a detection circuit to determine when a power consumption reaches a threshold level;

    a separation circuit to decouple the inductive power apparatus and the alternating current power source when the power consumption is lower than a threshold level to limit a vampiric power consumption of the inductive power apparatus; and

    a bypass circuit to initiate a charging sequence by electrically coupling the alternating current power source and the inductive power apparatus when a bypass input is initiated.
