Nickel-Hydrogen Multicell Common Pressure Vessel Battery Development Update 929320
The multicell common pressure vessel (CPV) nickel-hydrogen (Ni-H2) battery manufactured by Johnson Controls Battery Group, Inc. has completed full flight qualification, including random vibration at 19.5 g for two minutes in each axis, electrical characterization in a thermal vacuum chamber, and mass-spectroscopy vessel leak detection. A first launch is scheduled in 1992. Several new design variations, ranging from 9 Ah to 125 Ah and 12 to 32 volts, in 12.7 cm (5″) and 25.4 cm (10″) diameter vessels have been developed and prototypes fabricated for a variety of customers. Designs for smaller capacity, smaller diameter (6.4-8.9 cm) and higher voltage (up to 100 volts) are in progress.
The CPV battery offers cost and weight savings of up to 30% as compared to traditional nickel-cadmium (Ni-Cd) and individual pressure vessel (IPV) Ni-H2 batteries. The fully qualified design provided a 50% weight savings over its Ni-Cd predecessor for the same application. The reduced volume of the CPV also provides a significant advantage over IPV technology. Resistance data shows a further advantage as compared to IPV Ni-H2 and even Ni-Cd.
