Evaluation of electric vehicle battery systems through in-vehicle testing. Sixth annual report, 1990: Final report
- Electrotek Concepts, Inc., Chattanooga, TN (United States). Electric Vehicle Test Facility
This sixth annual summary report documents the tests performed from October 1989 through September 1990. The testing was performed at the Electric Vehicle Test Facility (EVTF) in Chattanooga, Tennessee. The objective of the battery activity is to identify long-life, low-cost, reliable batteries with sufficient energy and power to meet EV performance requirements. The program has identified the Chloride Electric Vehicle Systems (CEVS) 3ET205 tubular positive plate lead acid and Eagle-Picher Industries (EPI) nickel/iron batteries as near-term propulsion battery options for EV applications. The focus of the work was on the testing and evaluation of electric vehicles (EVs), batteries, and associated component systems. A total of six CEVS lead-acid battery packs was evaluated in the Griffon and G Van electric vehicles and one EPI NIF270 nickel/iron battery pack was bench-tested. The testing activities included the static load test, 35 mi/h constant speed range test, SAE J227a C Cycle range test, and logging battery pack watering and other maintenance requirements. The GM Griffon vans used for the battery testing are electric passenger vans produced in the United Kingdom by Bedford, a General Motors (GM) Corporation subsidiary. They are the predecessor of the G Van and use a CEVS 216-volt propulsion system. These vehicles have a 1800-lb payload capacity and have a floor line similar to internal-combustion-engine vans. The battery pack consists of thirty-six 3ET205 modules connected in series. The battery pack layout is similar to the G Van battery pack except there are 6 rows of 6 modules. Two designs of G Vans were tested at the EVTF. One is referred to as the Vehma G Vans and the other as Cars and Concept (C&C) G Van. The Vehma G Vans are passenger or cargo vans. The Vehma G Van is based on a production GM full-sized passenger van. Both design G vans use a 216-volt propulsion system designed by CEVS.
