Abstract: This invention enables Electric Vehicle (EV) charging requirements to be supplied by electric power available off-peak without increasing demand charges. It does this by continually measuring primary loads and enabling EV charging to utilize only that power that will not increase total demand. Grouping software available from Electric Vehicle Service Equipment (EVSE) suppliers allows the available power to be shared among multiple vehicles.

Abstract: This invention embodies a system and a method for charging electric vehicles comprising, a solar canopy over selected parking spaces, and control equipment and software to maximize the use of solar energy, minimize demand charges and allow for ancillary services to the grid. The capacity of the solar canopy is such that it is capable of providing the energy needed to operate the vehicle both for commuting and for all other uses except for trips over 2-300 miles, as provided by the control software. The system can include features for allowing access only to authorized users, for measuring the amount of energy used by each, and for monthly billing.

Abstract: This invention enables Electric Vehicle Service Equipments to control external electrical loads, such as water heaters. The parallel electric energy demand of the external load augments the remotely controllable energy demand for charging the vehicle creating a larger controllable demand than for charging the vehicle only. This larger demand is useful in responding to requests for ancillary service from the grid and can increase the revenue for regulation services.

Abstract: This invention has as its objective provision of a method and apparatus to enable the batteries of Electric Vehicles (EV)s to level the electric demand in buildings to reduce demand charges based on instantaneous demand for electric power. This load leveling is done by connecting the EV to the building electrical system by its conventional Alternating Current (AC) recharging connection, and by an additional Direct Current (DC) path supporting intermittent loads. In this way the EV battery stands between the AC energy source and the intermittent load and reduces the electric power drawn from the grid to a constant minimum level, thereby minimizing demand charges.
