ELECTRIC VEHICLE SUPPLY EQUIPMENT
First Claim
1. Electric vehicle supply equipment, comprising:
- an enclosure;
an electric vehicle supply circuit for providing a flow of current to an electric vehicle from a power source;
a charge circuit interrupting device located within the enclosure, the charge circuit interrupting device being arranged to interrupt the flow of current to the electric vehicle;
a grounding monitor circuit located within the enclosure, the grounding monitor circuit coupled to grounding conductors, the grounding monitor circuit having a grounding output signal;
a ground default detection circuit located within the enclosure, the ground fault detection circuit coupled to current carrying conductors, the ground fault detection circuit having a fault detection output signal;
a controller located within the enclosure, the controller coupled to the grounding monitor circuit, the ground fault detection circuit and the charge circuit interrupting device, where the controller is constructed and arranged to control the charge circuit interrupting device by providing a control signal to the charge circuit interrupting device; and
logic arranged to receive the grounding and fault detection signals and the control signal, and assert a close signal based upon the grounding and fault detection signals.
