Requirement of Testing to Li-Ion Batteries for Launch by ISS

Launching CubeSats from ISS is under strict requirements, and one of those requirements are the exhaustive tests of the power subsystem, which aim the safety of the ISS crew. The Li-ion batteries must have protection against short circuit, intern balance, overvoltage and undervoltage. This paper presents the results of the battery tests and analyses, of the CubeSat AESP-14, developed by ITA (Technological Institute of Aeronautics).
