Data Acquisition Tool for Hybrid Electric Vehicles The National Renewable Energy Laboratory's Advanced Vehicle Systems Branch is responsible for collecting data from the Hybrid Electric Vehicle Challenge, a student engineering competition which will involve 42 vehicles from the United States and Canada in June 1994. The purpose of this project was to design, program, test, and document a Windows-based program to display, store, and analyze the data taken during the competition.
Design/Build Workshops Global Light and Power offers workshops developed for use in schools, clubs, neighborhood groups, and social organizations who want to quickly learn basic skills in actual construction of Electric Vehicle and Alternative Energy systems. All workshops consist of actually building a complete system which the sponsor keeps for their own use. Workshop costs include all components used in the demonstration system built. After an introductory review of the elements of the system, workshop participants actually perform the system construction under supervision. Workshops offered: Electrathon Competition Engineering; Electric Vehicle Conversions; Basic Home Power Systems; and Water Pumping With Solar Electric.

Downloading and Installing MotoCalc for Windows 95 or NT 4.0 MotoCalc is a program for predicting the performance of an electric model aircraft power system, based on the characteristics of the motor, battery, gearbox, propeller, and speed control. You can specify a range for the number of cells, gear ratio, propeller diameter, and propeller pitch, and MotoCalc will produce a table of predictions for each combination. MotoCalc will predict current, voltage at the motor terminals, input power, output power, power loss, motor efficiency, power-loading, propeller RPM, static thrust, pitch speed, and run time. By producing a table of predictions, MotoCalc lets you determine the optimum propeller size and/or gear ratio for your particular application.
Dr. Range: EV Performance Analysis Software Have you ever wondered how far a given electric vehicle will really go? Have you ever wanted to quickly check the practicality of a new design? Have you ever lost a race because you weren't sure what your optimum cruising speed was? For design, analysis, racing, and touring Dr. Range computes the range of Electric Vehicles (EV's).
Electric Vehicle Battery Characteristics The Technical Research Center is using a battery charge/discharge test unit to perform charge/discharge characteristics testing in order to gain an understanding of the performance of electric vehicle batteries. The tests utilize batteries that meet the same standards as those currently being used in Chugoku Electric's electric vehicles. Such tests simulate actual driving conditions and charge/discharge patterns.
ELECTRIC VEHICLE TECHNOLOGY COMPETITIONS, LTD. (EVTC) EVTC was created in February, 1995 as an alliance of electric vehicle industry stakeholders promoting electric vehicle competitions as a means to increase public awareness of electric vehicles, further education in electric vehicle design and infrastructure, and advance electric vehicle technology in an effort to support commercialization of alternate fuel vehicles in accordance with Energy Policy Act mandates.
Introduction to Vehicle System Dynamics The design of passenger cars, and ground vehicles in general, is becoming an increasingly complex multi-disciplinary engineering task. On-board digital computers control the forces and moments generated by hydraulic actuators and electric motors that greatly influence the dynamics of motion of the ground vehicle. As in classical dynamics, the field of vehicle system dynamics explores and analyzes the relationship between forces and moments and the resulting position, velocity, and acceleration of the ground vehicle. These forces and moments may result from surrounding environment, such as road roughness or air drag, or they may be internally generated forces and moments produced by vehicle subsystems, such as the engine, powertrain, or the suspension mechanisms.

New and Familiar Drive Concepts in Direct Comparison Varying approaches have been taken in the research and development work carried out in the field of environment-friendly drive systems, which has been considerably intensified over the past few years. However, it is difficult to make a direct comparison between such systems, since various categories of vehicle with different power ratings are invariably involved. By applying various data relating to driving operation and fuel production to a fictitious vehicle, the Daimler-Benz researchers have now succeeded in carrying out a comparison of these systems. Their investigations focused on the fuel cell (with hydrogen derived both from natural gas at the refinery and from methanol on board the vehicle), the electric drive unit and – as conventional drive systems – the petrol and diesel engines.
Optimal Control of Electric Motors The objective of this proposal is to develop a set of energy efficient optimal controllers for the three major classes of electric motors: separately excited dc-motors, ac-synchronous motors, and ac-induction motors. The motivating application for these new controllers is electric vehicle propulsion systems.
SIMPLEV® - Simulating Electric & Hybrid Vehicles SIMPLEV® is a DOS based Electric and Hybrid Vehicle simulation program developed by the Idaho National Engineering and Environmental Laboratory. It's main use is as a vehicle performance simulation tool which capable of simulating vehicles having conventional, all electric, series hybrid, and parallel hybrid propulsion systems. SIMPLEV® is general enough to simulate vehicles ranging in size from small purpose-built vehicles (such as golf carts) to freight train locomotives. SIMPLEV® provides second-by-second predictions of powertrain component performance parameters over any user specified speed-time or speed-distance driving regime.
Testing Electric Vehicles - From Bench Measurements to On-road Performance To combat the problems of atmospheric and noise pollution of major urban centres, electrically-powered vehicles provide effective solutions for both individual and collective use. Before setting up an infrastructure, it is necessary to test the electric vehicles, together with their main components such as their drive train and their recharging system.
