nicdbattery: Spacecraft Battery Cell Accelerated Life Test

In Auburngrads/SMRD.data: Statistical Methods For Reliability Data - Datasets

Description

Brown and Mains present the results of an extensive experiment to evaluate the long-term performance of rechargable nickel-cadmium battery cells that were to be used in spacecraft. The study used 8 experimental factors. The first five factors are environmental or accelerating factors (set to higher than usual levels to obtain failure information more quickly). The other three factors were product-design factors that could be adjusted in the product design to optimize performance and reliability of the batteries to be manufactured. The experiment ran 82 batteries, each containing 5 individual cells. Each battery was tested at a combination of factor levels determined according to a central composite experimental plan.
