Evaluation of near-term electric vehicle battery systems through in-vehicle testing: Second annual final report
This report documents the performance from October 1985 through September 1986 of the Tennessee Valley Authority's ongoing project to evaluate near-term electric vehicle traction batteries. This second annual report includes the addition of four new batteries and the termination of two sets. The purpose of this field test activity is to provide an impartial evaluation and comparison of battery performance in a real-world operating environment. Testing includes initial acceptance testing of battery components and systems, daily in-vehicle operation of the batteries, monthly in-vehicle driving range tests, and periodic static (constant current) discharge tests under computer control. Battery performance data is typically presented on the basis of specific energy versus accumulated vehicle mileage and vehicle driving range over fixed operating cycle (35 mi/h) constant speed (SAE J227a ''C'' Cycle). Data is analyzed statistically with variable conditions normalized. The life-cycle is terminated when a battery system's measured capacity drops below 60 percent of rating (at the 2-hour rate) and/or after 25 percent of the battery modules have been replaced. 120 figs., 2 tabs.
