Abstract
A charging device includes a current control device configured to receive a first amount of current from a power source. The charging device also includes a ground detection module including a leakage circuit configured to direct a second amount of current to ground to generate a leakage voltage and a comparison circuit configured to detect a connection to ground of the charging device based on the leakage voltage generated. The charging device also includes a controller coupled to the ground detection module and to the current control device. The controller is configured to enable the first amount of current to be supplied to a power storage device of an electric vehicle when the connection to ground is detected.
