Project update: Developing intelligent battery management system for lead batteries in wind and solar applications

Project

Grid energy storage performance improvement using optimized electronic control

Goal

The project aims to improve the cycle life of lead batteries (in line with CBI’s KPIs as listed in the Technical Roadmap) for utility and renewable energy storage applications through the use of tools such as controlled overcharging and through the development of novel battery management systems.

Contractor(s)

Electric Applications Incorporated (EAI)

Initial findings

The project aims to increase operational life by developing novel charging algorithms applicable to different types of lead batteries. The first phase of work has focused on adapting a controlled overcharge approach to several types of lead batteries acquired from commercial sources. These batteries have been combined into representative strings, mimicking the conformations present in large energy storage system (ESS) products with testing currently underway.
