TESTING OF NiCd CELLS OVER GEOSTATIONARY ORBIT TYPE CYCLING PERIOD

摘要

Geostationary orbit type cycling was carried out in order to permit NiCd cell lifetime to be assessed as a function of temperature, charge rate and factor, and depth of discharge in unlimited charge mode operation. A second objective was to collect information on correlation between cell operation in geostationary orbit type cycling and operation under fixed depth of discharge cycling conditions. Tests performed on 180 NiCd cells are described and data collected during 2 years' cycling are presented. (Author)
