The Analysis of Voltage-Limited Battery Charging Systems

This paper discusses the techniques and problem areas associated with the charging of sealed secondary batteries for spacecraft, and the operating characteristics of the modified voltage-limited charging system. An approach is described for the characterization of battery parameters. The method of selection of a suitable voltage-temperature limit, with regard to battery parameters and system performance requirements, is described. A 4 ampere-hour battery system is analyzed, and its capability is defined parametrically.
