Abstract
Systems and methods for operating an electric energy storage device are described. The systems and methods may reduce a voltage potential between a ground reference and terminals of an electric energy storage device. By lowering the voltage potential, a possibility of unintentionally discharging the electrical energy storage device to ground may be reduced.
