EXPORT FUNCTION PREVENTION OF ELECTRICITY SUPPLY FOR ELECTRIC VEHICLES

Abstract

An electric vehicle supply system (EVSE) comprises an enclosure with an internal circuit that includes ground and power line assemblies terminating in busbars, a power cable with a vehicle coupler, and a ground monitoring impedance circuit. The circuit is designed to automatically cut off power to the system if the enclosure is removed from a mounting tray while the busbars are energized. The ground monitoring impedance circuit detects faults and triggers switches to open when impedance thresholds are exceeded. Additionally, the EVSE supports bidirectional power flow between the vehicle and the electrical grid.
