A Universal Battery Management System Using Novel Algorithms for Battery Health

Battery Management Systems (BMS) are critical components of lithium-ion (Li-ion) battery packs. They improve safety, extend life, ensure reliability and thereby reduce costs. However, without careful design and implementation they can actually degrade battery performance, result in lower reliability, add greatly to system costs and even create instead of reduce safety problems. TDA will develop a modular based BMS with universal applicability to battery chemistries and pack size (voltage and capacity). The modularity will allow its components to be customized for specific battery packs without driving a re-design of the entire BMS. We will develop new state of health (SOH) and state of life (SOL) determinations based on advanced algorithms, which will be capable of learning based on the data collected during operation of the battery pack. The project will benefit from years of BMS design experience using the electrochemical expertise of the PI.
