Form 9.B Project Summary






Project Title:

Application Specific, Optimum

Performance Design for

Nickel-Hydrogen Cells and Batteries

Technical Abstract (Limit 200 words)

Given the high level electrical performance

requirements for a specific space application, it is

desired to select a battery configuration that most

effectively meets the mission requirements in terms

of energy density, life cycle cost, cycle life,

spacecraft orbit, and power system redundancy. In

determining the most effective cell/battery

configuration, large numbers of variables must be

traded in order to arrive at the most effective

solution. These variables include such items as

power system architecture, battery chemistry, cell

dimensions, internal component selection, heat

rejection requirements, etc.

The objective of this project is create a rule based

system that captures expert rules, i.e. collective

industry experience, for selecting the ideal

Nickel-Hydrogen cell and battery configuration for

a given application. All configurations designed by

this system would be in keeping with current

industry practices. This system would serve as a

foundation for a system that would ultimately

include all pertinent battery chemistries and their

associated cell and battery configurations. In

addition to an intensive focus on electrical

performance, a fully implemented system would

also evaluate complete structural and thermal

concerns; concerns critical to accurate weight


Potential Commercial Applications (Limit 200 words)

Resulting from this contract will be a fully

functional, rule based technology, ANSYS finite

element interface. This interface will interpret

geometry created by a rule-based model and create

the corresponding thermal and structural finite

element models. This interface will enable

extremely rapid thermal and structural finite

element analysis (FEA). Rapid and accurate FEA is

an issue relating to virtually all

design/manufacturing organizations. Aerospace,

automotive and many other industries rely on such

analysis. Order of magnitude acceleration of this

type of analytical work is of great interest to

ANSYS Inc., the supplier of the ANSYS finite

element code.
