Testing of Nicd Cells over Geostationary Orbit Type Cycling Period.

摘要

The best charge current of Ni/Cd batteries at a given temperature and a given depth of discharge (d.o.d.) was determined. This was achieved by testing a number of cells under continuous cycling of 24 hours (22.8 hours charge and 1.2. hour discharge). A comparison was also made between the cycling routine with variable charge/discharge time for those depths of discharge averaged on the eclipse duration and the similar rate of charge. The test was performed on 180 sealed cells. The test program demonstrated that temperature is the most important factor affecting cell behavior. Cell operation is good at minus 10 C and + 10 C at any d.o.d. considered, while at + 30 C operation is generally bad. With a few exceptions, cells undergoing the cycling still work after about 440 cycles.
