1. A device for balancing a flow of electrical energy from a vehicle to a power source that is positioned external to the vehicle, the vehicle being arranged to form a differential resistance, the device comprising:

  • a balance circuit being configured to receive an input current signal from the power source and to transmit an output current signal to the power source for charging at least one storage element in the vehicle, wherein the differential resistance causes the input current signal and the output current signal to differ by a differential current amount, the balance circuit comprising;

    a current measuring device being configured to generate an output differential signal corresponding to the differential current amount; and

    a current generating device being configured to;

    generate a compensated current signal that is generally similar to the differential current amount in response to the output differential signal; and

    adjust the output current signal with the compensated current signal such that the output current signal is generally similar to the input current signal.
