Battery Voltage Fluctuations during Penumbral Passage

Abstract

The effect of power system load fluctuations on nickel-hydrogen battery cell voltage has been examined during simulated transit from discharge to charge as a satellite traverses a penumbral region of space The types of cell and battery resistances that can affect the voltage ripple are identified and measured for an aged 60-Ah nickel-hydrogen cell, and are found to range from 0.95 to 1.25 V for a 22-cell battery for 30-A load fluctuations The highest voltage ripple occurs at the low est battery state of charge and at the lowest battery temperature These measurements provide voltage regulation guidelines for satellite power systems
