APPARATUS AND METHOD FOR BALANCING THE TRANSFER OF ELECTRICAL ENERGY FROM AN EXTERNAL POWER SOURCE TO A VEHICLE
First Claim
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.

Abstract
In at least one embodiment, a device for balancing a flow of electrical energy from a vehicle to an external power source is provided. The device comprises a balance circuit being configured to receive an input current signal from the power source and to transmit an output current signal to the external power source for charging a element in a vehicle. A differential resistance causes the input current signal and the output current signal to be different. A current measuring device is configured to generate an output differential signal indicating a difference between the input and output current signals. A current generating device is configured to generate a compensated current signal in response to the output differential signal and to adjust the output current signal with the compensated current signal such that the input and output current signals are generally similar to one another.
