EVTF personnel tested 10 batteries, including lead-acid (flat plate and tubular design), Gel Cell III, advanced lead-acid, nickel iron, nickel zinc, nickel cadmium, and zinc chloride systems. The assessment encompassed the following tasks: initial acceptance testing of battery components and systems, daily in-vehicle operation of the batteries, monthly in-vehicle driving range tests, and periodic static discharge tests under computer control. Performance data were based on specific energy versus accumulated vehicle mileage and vehicle driving range over a fixed operating cycle at 35-mph constant speed and the SAE J227a C cycle. A battery's life cycle was terminated when its measured capacity dropped below 60% of the rating, at a 2-h rate, after 25% of the battery modules had been replaced. The EVs used for the tests were 10 Volkswagen vans and 2 General Motors Griffin vans.
