Low-Earth-Orbit and Geosynchronous-Earth-Orbit Testing of 80 Ah Batteries under Real-Time Profiles

To date the LEO battery has completed 5000 nominal cycles.The EODV is trending down by 50mV per 1000 cycles. To date the GEO battery has completed 2 nominal shadow periods and currently in sunlight period. Batteries testing after one year looks encouraging for aerospace application. There are no discrepancies between the current data and extensive testing conducted at Saft over the past 5 years

Low-Earth-Orbit and Geosynchronous-Earth-Orbit Testing of 80 Ah Batteries under Real-time Profiles

This viewgraph presentation gives an update on test results from two 16 cell batteries, one in a simulated Low Earth Orbit (LEO) environment and the other in simulated Geosynchronous Earth Orbit (GEO) environment. The tests measured how voltage and capacity are affected over time by thermal cycling
