Abstract	The battery is the energy storage device of the satellite power system. The working life of power system mainly depends on the life of the battery. The health state of the battery refers to the battery current performance deviation from the nominal design performance and indicators, so the performance of the battery in the future can be judged by the health state of the battery. Therefore, the study of the battery health assessment method has an important reference value on the design and the management of the satellite on-orbit. First, the aging and failure of GEO satellite battery is introduced, and the battery structure of the GEO satellite power system is analyzed in this paper. Then the evaluation method of GEO satellite battery based-on fuzzy theory is studied, the flow of the assessment of the battery health status, the calculation method of the symptoms membership degree and weight evaluation matrix are given, the calculation method of the Degree of Failure (DOF) and Degree of Health (DOH) is given, too. Using this method, the health state of the satellite battery can be evaluated and diagnosed. Furthermore, in the simulation experiment, the GEO satellite battery charging and discharging data of 3 years are used to evaluate the health condition, the effective, reliability and accuracy of the battery evaluation model proposed in this paper are also proved out and verified.
