Abstract :
Cells from the flight lot of the Mars Global Surveyor (MGS) battery were configured as a test pack and underwent characterization tests. The MGS battery is based on 20 ampere-hour 2-Cell common pressure vessel (CPV) technology. The primary goal of the current CPV characterization test was to understand how (Ni-H2) V/T curves would map onto the Ni-Cd curves existing in spacecraft hardware. To that end, (Ni-H2) V/T curves were experimentally determined. The results of that determination are described in this paper
