In this subtask we will use a specialized cell container, where the strength of the positive paste can be measured using a load cell. After the paste is formed and cycled, we will overcharge the cell using different overcharge factors. We will then determine the strength of the paste as a function of the amount of overcharge. This relationship will be important for modeling battery life. The conductivity model previously developed to predict battery performance will be used to predict battery life.
Failure is defined to occur when the battery can no longer provide the required energy.
We will also submit at least one paper to the Journal of Power Sources and report our results at conferences so that our results will appear in the open literature. The critical component for HEVs is the battery. Technology Transfer Activities Work with battery manufacturers to develop the high power, horizontal plate battery design. Develop battery models so they could be commercially marketed to battery companies. Publish and disseminate research findings concerning the performance and life of lead acid batteries.
