Keynote Speech: Design and Development of Smart Battery Management Systems using Advanced Digital-twin/AI/ML Techniques

Abstract: It has become imperative to find a solution to manage energy production and usage accurately, especially within the context of future electric energy storage for e-transportation systems. Enhancing the life of Lithium-ion (Li-ion) battery packs has been the topic of much interest. In this framework, the role of on-board cell voltage balancing of Li-ion batteries will be highlighted in this talk. This is a very important topic in the context of battery energy storage cost and life/state-of-charge, SOC/state-of-health, SOH monitoring. Li-ion batteries, although popularly proposed for electric transport, have been highly uneconomic for energy storage, overshooting cost requirements by a large margin. This talk will also introduce a first-of-its-kind closed-loop cell charge (voltage) balancing and extreme fast charging technique. The technique uses instantaneous cell voltage and/or temperature rise (ΔT) as a control parameter. Finally, this talk will also address the opportunities of applying Machine learning (ML), Internet-of-things (IoT), and Digital Twin technologies in the domain of Li-ion battery management systems (BMS). Several practical examples of BMS, industry standards, and testing facilities will be shown to encourage more research and developments in the focused field.
