Behavior of a cycled Ni-Cd battery during pulse discharge

The pulse discharge behavior of a 9-Ah, 12-V nickel-cadmium (Ni-Cd) battery fabricated for the FAST program was studied. The response of the battery voltage to a pulse with a current of 60 A and duration of 10 to 200 ms was measured, along with the capacity remaining at the end of pulse discharge. The maximum drop in voltage at the beginning of the pulse was 505 to 1,049 mV, and battery capacity remained stable.
