✦ Synopsis

NiCd cell and battery behaviour was studied in typical spacecraft operating conditions, both theoretically and experimentally. The first stage of the study consisted in generating a model for the temperature distribution inside the cell for given heat generation values and confirming its validity through specific tests.

The second stage consisted in predicting heat generation inside the cell in different operating conditions and checking prediction validity through testing.

The third stage consisted in generating by network analysis a model of the thermal behaviour of a full-scale battery in actual spacecraft operating conditions. Experimental results were very close to results of the battery simulation exercise.

The battery simulation model produced can be used to predict the thermal behaviour of a NiCd battery in most of the possible spacecraft operating conditions.
