Abstract: Based on the layout of the GEO communications satellites bus, the thermal math model (TMM) of south satellite battery cabin was presented to analyze the mathematical mechanism that influences battery temperature on orbit. It is shown that daily change of orbit heat flux will obviously influences the temperatures of west board, +Y panel of Earth deck and +Y panel of anti-Earth deck, and further influences the temperature of service module (SM) structure board through radiation, which induces the battery temperate variation through SM board conduction. This is the key reason of battery temperature variation.
