Evaluation of Advanced Lead-Acid Batteries Developed for Load-Leveling Applications

摘要

Argonne National Laboratory has conducted an extensive evaluation of an advanced lead-acid battery developed by Exide Corporation for load-leveling applications. This paper presents the results of tests and analyses conducted on three 3100-Ah batteries over a five-year period. The Exide batteries demonstrated their high reliability and long life by completing over 2300 deep discharge cycles under accelerated life testing conditions at 50 sup 0 C, the equivalent of over 6400 cycles or 25 years of operation for the electric utility application. This paper also describes the thermal characteristics and operational reliability of this battery technology. (ERA citation 13:014773)
