Abstract
An electric vehicle (EV) charging system includes a plurality of electrical vehicle supply equipment (EVSE) units, a plurality of associated EV charging stations, phase conductors coupled between the charging stations and corresponding bi-directional solid-state switches and a neutral conductor configured to complete charging circuits with associated ones of the phase conductors, and an EVSE communications bus. Each EVSE unit includes a microcontroller unit (MCU) and driver that control current flow through the bi-directional solid-state switches providing charging current to respective EV charging stations and connected plug-in EVs (PEVs). The MCUs communicate over the EVSE communications bus and, as PEVs plug into, charge, and unplug from the plurality of EV charging stations, reallocate or reapportion an available supply current among the plurality of EVSE units while also dynamically adjusting one or more circuit protection attributes provided by the EVSE units.
