S01 - Advanced Power Electronics for Smart Battery Testing, Analysis, and Digital Twin-Based Battery Management Systems

Batteries play a pivotal role in ensuring the long-term technical and commercial success of e-mobility. Their dynamic characteristics necessitate rigorous testing and analysis to ensure battery safety, reliability, and performance. Testing and analysis not only underpin innovation, but also contribute to the sustainability of battery technology and its applications. Keeping this in mind, this professional education seminar will comprehensively address a wide array of testing techniques, standards, and market-available products. Notably, battery degradation is pronounced during low-temperature fast charging. Thus, few health-conscious fast charging methods and associated power electronics will be discussed. Given the intricate and sensitive nature of LIB behavior under varying conditions, implementing intelligent safety frameworks and smart battery management systems (BMS) becomes paramount. Here, a detailed discussion on the functionalities of BMS and associated power electronics converters will be discussed. For effective BMS operation, detailed information of battery states and aging profiles are indispensable. Recent strides in cloud computing, digital twin technology, artificial intelligence and machine learning-based state estimators hold substantial promise in addressing these challenges. Hence, the latest progress and emerging trends in these domains, including thermal management control and the IoT will be discussed, catering to researchers and development engineers alike.
