The composition of the battery pack, the test conditions of the mechanical environment of the battery pack and the simulated GEO test system are briefly introduced. In terms of battery performance, the discharge characteristics of 79% DOD during the middle of the first shading period and the middle of the 36th shading period are compared, and the relationship between the temperature characteristics of charging and discharging and the variation of the hydrogen pressure is introduced. Especially in life characteristics, The end-of-stack voltage change characteristics of the battery pack at maximum depth of discharge for 40 shadings at GEO, 79% DOD, battery capacity change, and change in end-of-discharge voltage at shading 36 and 36 shading. Also listed the main technical performance of the battery pack.
