inaktif: "kendime not #2": kendime not #2 Flight Demonstration of a Hybrid Battery/Supercapacitor Energy Storage System in an Earth Orbiting CubeSat The JPL/CSUNSat1 project successfully demonstrated a hybrid ESS consisting of a Li-ion battery and SC technologies in flight onboard a 2U tumbler CubeSat. Both the primary and extended mission phases were completed successfully. The performance characteristics of the payload hybrid ESS in flight were in excellent agreement with ground test results, particularly with respect to the percent of capacity contributions between the Li-ion cell and the SC. The large differences in internal resistances from flight experiments as compared to ground tests were attributable to significant ohmic resistances of the payload battery interconnects (i.e., leads, connectors, etc.) and not due to the inherent cell impedances. Despite operating in LEO, the spacecraft was able to achieve sub-zero temperatures critical for flight experiments on JPL’s cold capable hybrid ESS.
