Performance Tests of 22 Ah Metal Hydride Prismatic Design Cell Pack for Aircraft Applications 2002-01-3213
The Air Force Research Laboratory, Energy Storage and Thermal Sciences Branch conducted performance tests of 22 Ah nickel-metal hydride (Ni-MH) cell packs containing four prismatic sealed design cells over the operational temperature range for a modern fighter aircraft at the C/2, C and 2C rates. Capacity tests indicated satisfactory performance at the C/2 and C rates down to -30 °C and at the 2C rate down to -20 °C.
Self discharge tests at elevated temperatures up to +60 °C were also conducted. Test results will be presented and implications for further development of an environmental main aircraft battery will be discussed.
