Abstract:

TX-2 satellite Li-ion Battery produced by SISP was first applicated on GEO satellite. Technical requirements of Li-ion battery with long life and high reliability were put forward.In-orbit management policy and failure isolation technology were put forward to meet the technical requirement.Technical proposal, performance tests, and in-orbit behaviour of the Li-ion battery used onboard TX-2 satellite were introduced in this paper. During in-orbit operation，Li-ion batteries had good performance, good consistence between cell packages and valid in-orbit management policy. The in-orbit date indicated that the Li-ion battery used onboard TX-2 satellite had good in-orbit performances and the battery on ground design was fully valided. The success of launching and in-orbit operation of TX-2 satellite battery provides a foundation for widely using Li-ion battery onboard GEO satellites.

Key words:  Li-ion battery, GEO satellite, performance tests, in-orbit management policy, in-orbitoperation
