Abstract: A system for generating a local autonomous response to a condition of an electric grid by electric vehicle charging stations, comprising: a first electricity meter for reading current, frequency, or voltage from a first electricity supply line to one electric vehicle charging station; a second electricity meter for reading an electric current, frequency, or voltage from the electric grid supplying the plurality of electric vehicle charging stations; a third electricity meter for reading current, frequency, or voltage from a third electricity line from one or more renewable generators; and an electric vehicle charging controller operatively coupled to the first electricity meter, the second electricity meter, the third electricity meter and the electric vehicle charging stations and operable to obtain readings from the first electricity meter, the second electricity meter and the third electricity meter and to control the electric vehicle charging stations based on the obtained readings.

Abstract: Described is an electric vehicle conversion system and method comprising one or more battery packs disposed within one or more battery pack enclosures, a frontal mounting subframe assembly and an electric motor mounting frame assembly. In one implementation, the vehicle conversion system incorporates six battery pack enclosures. The described components and assemblies are designed to simplify building an electric car on the basis of an existing vehicle chassis. The frontal mounting subframe assembly is designed to be securely attached to the vehicle frame using at least four bolts and is designed to securely hold two battery pack enclosures disposed under the front hood of the vehicle. The electric motor mounting frame assembly is designed to mechanically mate with the existing engine mounting points of the original vehicle and is attached to said points with at least two bolts.

Abstract: Described is a three-part electric vehicle drivetrain architecture incorporating (1) a hybrid motor assembly incorporating both AC and DC motor architectures to combine high power of the DC motor with the efficiency of the AC motor, (2) a power stage that delivers the precise amount of the electrical energy to the motors, and (3) a microprocessor-based control system that performs all the control functions of the drivetrain. In the hybrid AC/DC motor assembly, the DC motor and one AC motor are arranged back to back with their driveshafts mechanically coupled. In this arrangement, the motors are integrated into one unit by removing back/front plates and replacing individual shafts with a single shaft. Mechanical connection of such a motor assembly to the wheels is performed via the conventional transmission/driveshaft.

Abstract: Described is a Modular Instrumentation System for Electric Vehicle Data Acquisition, Analysis and Display, and Component Control. The system acquires data from and controls (where applicable) the multitude of devices that reside onboard and offboard of the electrical vehicle. For vehicles that have been converted from internal combustion (gasoline or diesel) engines to electric drive, this includes both the components installed as part of the conversion (such as electric motor, motor controller, battery pack and/or the battery management system, and charger), and the original components (such as speed sensor, distance traveled, braking and traction control systems—e.g. ABS and ETC, climate control, entertainment systems).

Abstract: An industry database and method of creating same is provided. The database is created in accordance with a process that includes: identifying a plurality of web sites meeting at least one search criteria; automatically extracting URL addresses for each of the plurality of web sites; automatically categorizing each of the web sites and their corresponding URL addresses in accordance with a predefined category structure; and automatically indexing and storing each of the URL addresses in accordance with the predefined category structure in the database. A method of using a database system is also provided.
