Research Activities

1. Rejuvenation of weak batteries to new condition, often over original rating.
   Recently we discovered a methodology which will rejuvenate sealed lead acid batteries, including electric car batteries, and restore them to their original ratings.
2. Life Cycle Testing, Accelerated Aging
3. Realistic EV Simulation using actual electric vehicle road test data
   The electric car can be simulated in the lab using data taken from a data acquisition system on an operational electric car to verify the battery design. We determine whether the batteries will be overcharging during braking or overdischarged during a high-speed run.
4. Mathmatical modeling of batteries
   A mathmatical model was developed for lead acid batteries which is widely used by battery manufacturers and users. A mathmatical model of NiCd batteries has also been developed.
5. Battery abuse testing including over discharge, overcharge, etc. to develop procedures which ensure long battery life.
6. Universal Charging Algorithm
   A Universla charging Algorithm is developed which will optimize the performance of most sealed lead acid, Nicke-Cadmium, and Nickel-Metal-Hydride batteries.
7. Small battery defects
   Research is conducted to detect defects in various types of small batteries such as Polaroid Zinc Manganese film pack types.
8. Effect of Temperature on battery performance
