Abstract

This report presents the test results for a functional model ac motor controller for electric vehicles and a three-phase induction motor which were dynamically tested on the Lewis Research Center road load simulator. Results show that the controller has the capability to meet the SAE-J227a D cycle test schedule and to accelerate a 1576-kg (3456-lb) simulated vehicle to a cruise speed of 88.5 km/hr (55 mph). Combined motor controller efficiency is 72 percent and the power inverter efficiency alone is 89 percent for the cruise region of the D cycle. Steady state test results for motoring, regeneration, and thermal data obtained by operating the simulator as a conventional dynamometer are in agreement with the contractor's previously reported data. The regeneration test results indicate that a reduction in energy requirements for urban driving cycles is attainable with regenerative braking. Test results and data in this report serve as a data base for further development of ac motor controllers and propulsion systems for electric vehicles. The controller uses state-of-the-art silicon controlled rectifier (SCR) power semiconductors and microprocessor-based logic and control circuitry. The controller was developed by Gould Laboratories under a Lewis contract for the Department of Energy's Electric and Hybrid Vehicle program.

Improved SCR ac-motor controller for battery-powered urban electric vehicles

Technical Report Latos, T

An electric vehicle propulsion system controller which uses an ac induction electric motor as the electrical to mechanical energy conversion unit was designed and developed. The contract program was to design and test an improved ac motor controller, which when coupled to a standard ac induction motor and a dc propulsion battery, would provide a complete electric vehicle power train with the exception of the mechanical transmission and drive wheels. In such a system, the motor-controller converts the dc electrical power available at the battery terminals to ac electrical power for the induction motor in response to the drivers commands.more »« less
AC propulsion system for an electric vehicle. Phase 1, final report

Technical Report Geppert, S

The object of this program was to develop and test a functional prototype of an ac propulsion system for an over-the-road electric vehicle. It was designed and fabricated from the ground up. The system consists of a two-speed, mechanically-shifted (hydraulic clutches) automatic transaxle, an 18.65 kW (25 hp) rated ac traction induction motor, a pulse-width-modulated (PWM) transistorized inverter, and an overall microprocessor-based vehicle/drive controller. It was shipped to LeRC September 2, 1980, where it will undergo further testing and evaluation on the Road Load Simulator. The system is sized to allow a 1450 kg (3200 lb) GVW vehicle to meetmore »« less
Tests of an alternating-current propulsion subsystem for electric vehicles on a road load simulator

Technical Report Stenger, F

This report presents the test results of a breadboard version of an ac electric-vehicle propulsion subsystem designed and built by Eaton Corporation under a cost-shared contract to NASA Lewis Research Center as a part of the US Department of Energy (DOE) Electric and Hybrid Vehicle Program. The breadboard was installed in the NASA Lewis Research Center Road Load Simulator facility and tested under steady-state and transient conditions. Steady-state tests were run to characterize the system and component efficiencies over the complete speed-torque range within the capability of the propulsion subsystem in the motoring mode of operation. Transient tests were performedmore »« less
Steady-state and dynamic evaluation of the electric-propulsion system test-bed vehicle on a road load simulator

Technical Report Dustin, M

The propulsion system from the electric propulsion system test bed vehicle was evaluated on the road load simulator (RLS). Track tests had previously been conducted. The electric vehicle was built from components representative of 1976 technology, including a series-wound dc motor and a commercially avaiable silicon-controlled rectifier (SCR) chopper type of controller. An 84-V battery pack was used with the system in the vehicle. A large motor-generator battery simulator was used in all of the RLS tests. Steady-state tests were conducted over a wide range of differential outputs and vehicle speeds. Efficiencies of the system and of the individual componentsmore »« less
