Abstract: A single electric vehicle charger for electrically connecting to multiple electric vehicles simultaneously while automatically charging the multiple electric vehicles sequentially. The charger includes an AC to DC rectifier, at least one ground fault circuit interrupter, and at least two physical electrical disconnects. The AC to DC rectifier electrically connects to an AC power source and allows DC batteries of the multiple electric vehicles to be charged from the AC power source. The at least one ground fault circuit interrupter is in electrical communication with the AC to DC rectifier and disconnects whenever current becomes unbalanced between an energized conductor and a return neutral conductor.

Abstract: An overhead mobile charger system for mounting between a pair of adjacent and spaced-apart rows of side-by-side parking spaces and exhibiting full circle traversing so as to reach and charge electric vehicles parked in the pair of adjacent and spaced-apart rows of side-by-side parking spaces. The system includes a single EV battery charger, a boom, and apparatus for rotatably mounting the boom over, and between, the pair of adjacent and spaced-apart rows of side-by-side parking spaces. The single EV battery charger has a power cable terminating in an EV connector. The power cable of the single EV battery charger runs along, and depends from, the boom, and together with the boom being rotatably mounted via the apparatus so as to allow the boom to exhibit full circle traversing, the electric vehicles parked in the pair of adjacent and spaced-apart rows of side-by-side parking spaces are reached and charged by the EV connector of the single EV battery charger.

Abstract: An overhead mobile charger system for reaching and charging electric vehicles parked in a pair of adjacent rows of side-by-side parking spaces. The system includes a rail, a pair of trolleys, a single EV battery charger, and apparatus for electrically connecting the EV battery charger to a power source without impinging upon movement of the pair of trolleys along the rail. The rail mounts overhead of, and traverses, the pair of adjacent rows of side-by-side parking spaces. The pair of trolleys are movably mounted along the rail and reach the electric vehicles parked in the pair of adjacent rows of side-by-side parking spaces. The single EV battery charger is mounted to, and moves with, the pair of trolleys to charge the electric vehicles parked in the pair of adjacent rows of side-by-side parking spaces.

Abstract: A controller for utilizing real-time surplus electrical energy available from a facility in which a modular system for charging electrical vehicles operates to allow more chargers to be installed and operational at the facility while avoiding costly and time-consuming infrastructure upgrades. The controller includes an EV charger interface, a facility energy management interface, and a distribution grid interface. The EV charger interface bidirectionally interfaces with EV chargers.
