Bipolar Lead Batteries for Energy Storage Systems Applications (ESS)
Partners
Gridtential Energy, Inc. and Electric Applications Incorporated (EAI) (USA)
Duration
April 2021 – July 2023
Objective
This project aimed to study Silicon Joule bi-polar batteries in packs that represent residential ESS coupled with solar power
Research priority
Optimize bi-polar batteries and battery management systems for ESS
See KPIs in our Technical Roadmap
Final results
• Detailed analysis of initial battery and battery pack data for standard IEC 61427-2 testing was performed.
• Test results showed differences in polarization and efficiency at high rate of discharge between bi-polar batteries and conventional batteries.
• Health of each battery module in a pack was determined by analyzing minimum discharge voltage, open-circuit potential and charge voltage.
