Battery Charge Equalizer System
A NASA invention available to explore as a licensing opportunity.
About this technology
Overview
A battery charge equalizer developed at NASA's Johnson Space Center provides individual cell charging in multi-cell battery strings using a minimum number of transformers. By effectively keeping all the cells in a multi-cell string at the same charge state, this technology maximizes the battery's life and performance. Designed to augment a simple high-current charger that supplies overall battery system energy, the innovation achieves equalization without wasting energy or creating excess heat. NASA's battery charge equalizer complements existing high voltage chargers and instrumentation systems and offers safe and low-cost management for lithium-ion (Li-ion) batteries used in electric vehicles and other next-generation renewable energy applications. This NASA Technology is available for your company to license and develop into a commercial product. NASA does not manufacture products for commercial sale.
