Performance of Improved Lead Acid Batteries for Electric Vehicles

摘要

New applications for lead-acid batteries, such as electric vehicle propulsion, demand high specific energy and power and good cycle life. A research and development program at Johnson Controls, Inc., sponsored in part by the United States Department of Energy through Argonne National Laboratory, has been underway since 1978 to develop advanced electric vehicle batteries. Cell test results on two Improved State of the Art (ISOA) battery designs developed under this program are described. Capacities and material utilization are shown as a function of both discharge rate and temperature. Cycle life data at 80 and 100% depth of discharge are presented and failure modes are discussed.
