VEHICLE TESTING OF NEAR-TERM BATTERIES

Vehicle tests on near-term batteries were conducted by the Jet Propulsion Laboratory to support the Department of Energy's Electric and Hybrid Vehicle research, demonstration, and development program. Four vehicles were used: South Coast Technology (SCT) Electric Volkswagen Rabbit; Jet Industries Electra Van 600; Electric Vehicle Associates Change-of-Pace Wagon; and Battronic Truck Corporation pickup truck. Two (Yardney, ERC) nickel-zinc batteries and one of nickel-iron (Westinghouse) were compared with an improved lead-acid battery (Globe-Union). Coastdown tests established road load characteristics for dynamometer calibration. Vehicles were then tested in their as-delivered condition to establish baseline performance, with the vehicle operating on a chassis dynamometer to maximize test repeatability by controlling environmental conditions and to facilitate instrumentation for measuring energy flow. Near-term batteries were connected to the vehicle propulsion system from an external battery tray positioned near the vehicle. Both baseline and near-term battery tests included constant speed tests at 35 and 55 mph and selected driving schedules (versions of Society of Automotive Engineers J227a). Tests completed only for the SCT vehicle showed that near-term batteries improved vehicle range at 35 mph but not at 55 mph. The baseline lead-acid battery pack delivered with the vehicle was quite consistent in repeatability and efficiency, although 3 of 18 original batteries failed after about 50 charge/discharge cycles. The nickel-zinc batteries showed indications of reduced cycle life and the nickel-iron battery had leakage problems and cell failures.
