Abstract: Before the aircraft launch, a series of tests should be carried out to the space batteries. However the environment on earth is quite different from in space, especially the weightlessness in space which it is difficult to simulate for a long period of time on earth, in order to achieve the purpose of the test. So the test data got on the ground may be different with the actual data. Thus, we invent a kind of calibration device which calibrate space battery for electrical properties under different acceleration.

Key words: Weightless, Space battery, Calibration device
