Claim 0:
1. An electric vehicle (EV) charging system, comprising:
a plurality of EV charging stations;
a plurality of EV supply equipment (EVSE) units associated with the plurality of EV charging stations, each EVSE unit including a microcontroller unit (MCU) and a solid-state switch that controls whether electrical current is able to flow to said each EVSE unit's associated EV charging station, wherein each EVSE unit of the plurality of EVSE units further comprises a closeable air gap connected in series with said each EVSE unit's associated solid-state switch, between input line-side terminals and output load-side terminals of said each EVSE unit and each EVSE unit is configurable in three possible states and at any given time is configured in one of said three possible states:
an ON state during which the closeable air gap is closed and the solid-state switch in said each EVSE unit is ON;
a STANDBY state during which the closeable air gap is closed and the solid-state switch in said each EVSE unit is OFF; and
an OFF state during which the closeable air gap is open and the solid-state switch in said each EVSE unit is OFF;
electrical power distribution wires or cables that distribute electrical power from the plurality of EVSE units to the plurality of EV charging stations;
an EVSE communications bus over which the MCUs in the plurality of EVSE units communicate, coordinate, and allocate or apportion an available supply current among the plurality of EVSE units,
wherein the plurality of MCUs is configured to reallocate or reapportion the available supply current among the plurality of EVSE units upon plug-in electric vehicles (PEVs) plugging into the EV charging stations to charge and upon PEVs completing charging and unplugging from the EV charging stations and the plurality of solid-state switches is configured to provide circuit protection to a plurality of associated EV charging stations and PEVs.
