Characterization testing of a 40 ampere hour bipolar nickel—hydrogen battery
Extensive characterization testing has been done on a second 40 ampere hour (A h), 10-cell, bipolar nickel—hydrogen (Ni—H 2) battery to study the effects of operating parameters such as charge and discharge rates, temperature, and pressure on capacity, A h and watt hour (W h) efficiencies, end-of-ch...

Summary: | Extensive characterization testing has been done on a second 40 ampere hour (A h), 10-cell, bipolar nickel—hydrogen (Ni—H
2) battery to study the effects of operating parameters such as charge and discharge rates, temperature, and pressure on capacity, A h and watt hour (W h) efficiencies, end-of-charge (EOC), and mid-point discharge voltages. Testing to date has produced many interesting results, with the battery performing well throughout the test matrix except during the high-rate (5
C and 10
C) discharges, where poorer than expected results were observed. The exact cause of this poor performance is, as yet, unknown. Small scale 2 in. × 2 in. battery tests are to be used in studying this problem.
Low earth orbit (LEO) cycle life testing at a 40% depth of discharge (DOD) and 10 °C is scheduled to follow the characterization testing. |
