PERFORMANCE OF 35Ah NICKEL-HYDROGEN BATTERY FOR AEROSPACE

The paper introduces the structure of the battery, aerospace mechanics environment test criteria and simulative cycle test procedures for GEO. In electrical performance respect, it compares the discharge characteristic of 79%DOD in the middle of the 1st eclipse season with the 36th eclipse season, and outlines the temperature characteristic of the charge and discharge period and the relation between capacity and hydrogen pressure. Especially in life performance respect it emphasizes the EOD potential characteristic in simulated GEO, 79%DOD and the maximum DOD of 40 eclipse seasons, the capacity change and the EOD potential change of the 3rd and 36th eclipse season of the batteries. The paper lists the primary technical performance indexes of the Ni H 2 batteries too.
