Abstract: This invention is based on the availability of Electric Vehicles with onboard inverters and receptacles to supply significant amounts of AC power from the main propulsion batteries of the vehicles. It embodies a system comprising an apparatus and methods for bidirectionally connecting one or more electric vehicles at a workplace or multifamily residence to one or more distribution panels supplying critical loads and one or more panels supplying interruptible loads such that the vehicle(s) can supply back up power to critical loads during a grid outage. The bidirectional connection also enables V2G operation to enable energy arbitrage, demand response, and ancillary services to the grid.

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 (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 consists of an apparatus to interface an electric vehicle battery with a solar photovoltaic system and a method of using the apparatus to provide back up power during grid outages and ancillary service revenue from the grid. The apparatus uses the solar PV inverter to provide bidirectional power flow from the battery during night-time hours, or whenever the solar array is producing insufficient power. The apparatus thus consists only of switches and control and measurement equipment. It relies on the otherwise underutilized inverter and the on-board vehicle battery charger as the power electronic components.

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 is a DC-coupled, non grid-tied system comprising a solar panel, or an array of panels, a storage battery, a battery charger, an inverter, and optionally, a connection to an electric vehicle via both the regular AC charging connection and a DC connection. Unlike conventional grid-tied solar systems there is no possibility of solar or battery energy being fed back to the grid by virtue of the one-directional flow of energy through the battery chargers. The system can utilize all of the energy produced by the solar panels to provide power to critical household loads by storing electric energy in the storage battery. In the event of a grid outage, the system maintains power to the critical loads to the limits of the capacity of the batteries and the inverter, supplemented by whatever solar power is available. The energy available in an outage can be supplemented by using the main propulsion battery of an electric vehicle.

Abstract: This invention consists of a method and apparatus to use an electric vehicle main propulsion battery to provide back up power during grid outages. It relies on simultaneous AC connection through an EVSE to the conventionally provided on-board vehicle battery charger and DC connection from the vehicle main propulsion battery to a stationary, ground-based inverter to provide bidirectional power flow to and from the vehicle. this bidirectional capability can provide back up power during grid outages and remunerative ancillary services to the grid. The DC connection to the vehicle battery may be indirectly through the on-board DC-DC converter and the low voltage accessory battery system or direct to the high voltage main propulsion battery. If the AC power source is connected to a solar array, the back up system can keep the array functioning through outages for an indefinite time and charge the vehicle for continued use.

Abstract: This invention consists of an apparatus to interface an electric vehicle battery with a solar photovoltaic system and a method of using the apparatus to provide back up power during grid outages and ancillary service revenue from the grid. The apparatus uses the solar PV inverter to provide bidirectional power flow from the battery during night-time hours, or whenever the solar array is producing insufficient power. The apparatus thus consists only of switches and control and measurement equipment. It relies on the otherwise underutilized inverter and the on-board vehicle battery charger as the power electronic components, thus minimizing cost.

Abstract: An improved drive assembly is described which can apply a pure torque to a driven member while allowing for limited motion of the driven member in the radial direction. This drive assembly is particularly suitable for converting an Internal Combustion (IC) vehicle to an IC-electric hybrid vehicle comprising installation of one or two electric motors coupled to a drive shaft of the vehicle via the drive of this invention such that the electric motor can provide some or all of the mechanical power required to propel the vehicle while accepting some relative motion between the existing vehicle drive shaft and the motors. The improvement consists of interlocked idler rollers mounted so as to reduce dynamic loads on the drive at high speeds, thus reducing noise and vibration.
