Time-to-failure analysis for NiCd batteries in a CPS orbit
Cells operating at five degrees Celsius or less, and going to 60 to 65 percent depth of discharge, were studied as to whether they could achieve a useful working life of 7.5 years in a GPS orbit. The characteristics of various orbits were compared and it is noted that the GPS orbit experiences only 220 cycles a year and must be treated as a geosynchronous rather than a low Earth orbit. Cell degradation is considered to be the result of both trickle-charge degradation and degradation due to cycling. Time-to-failure values are presented for selected temperatures and depth of discharges.
