1. A battery charging system comprising:

  • an isolation device comprising;

    an AC input terminal structured to receive AC power;

    an AC output terminal structured to provide AC power received with the AC input terminal;

    two DC output terminals structured to transmit DC power;

    a first portion of a detection circuit including a first sensor and a first resistor coupled in series, the first resistor being coupled in parallel to the two DC output terminals; and

    a first controller in communication with the first sensor and structured to selectively isolate the AC input terminal of the isolation device from the AC output terminal of the isolation device; and

    an electric vehicle charger comprising;

    an AC input terminal structured to be coupled to the AC output terminal of the isolation device;

    two DC input terminals structured to be coupled to the two DC output terminals of the isolation device; and

    a second portion of the detection circuit including a second sensor and a second resistor coupled in series, the second resistor being coupled in parallel to the two DC input terminals,wherein the first controller is structured to isolate the AC input terminal of the isolation device from the AC output terminal of the isolation device when the two DC input terminals of the electric vehicle charger are not coupled to the two DC output terminals of the isolation device.
