Development Survey of Space Power System Life Prediction

During spacecraft working on orbit, the performance of power system will be suffered degradation as the issue of space environment and power system’s working characteristics. The reliability and working life of space power system can be affected directly. Based on the working theory of space power system, the main factors which lead to the degradation of power were confirmed. In combination with the research progress in power life prediction, the difficulty and the subsequent main study direction in life prediction were bring forward. The studies can contribute to the engineering application of life prediction.
