Multiple cell CPV nickel-hydrogen battery

Abstract

Johnson Controls, Inc. has developed a multiple cell CPV nickel hydrogen battery that offers significant weight, volume, and cost advantages for aerospace applications. The baseline design was successfully demonstrated through the testing of a 26-cell prototype, which completed over 7000 44 percent depth-of-discharge low earth orbit cycles. Prototype designs using both nominal 5 and 10 inch diameter vessels are currently being developed for a variety of customers and applications.
