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. The facility energy management interface bidirectionally interfaces with a facility electrical monitoring system, and receives real-time current usage readings from the facility electrical monitoring system, and in response thereto, either cycles the EV chargers—via the EV charger interface—on or off to modulate power used at any point in time to stay within overall limits of the facility or reduces EV charging rate in order to make use of any unused electricity on a real-time basis so as to allow more chargers to be installed and operational at the facility while avoiding the costly and time-consuming infrastructure upgrades. The distribution grid interface bidirectionally interfaces with an electrical distribution grid electrically feeding the facility.
