Increasing demands of sustainability and electrification are driving development for customer and regulatory satisfaction, and battery systems are on the rise in several domains, such as railway, automotive, aerospace, etc. [1]. With the growing interest in battery technology advanced applications are continuously evolving to meet traditional challenges of performance, for example in the Electrical vehicle (EV) domain. More recently, technical advances have improved the run-time configuration of battery systems to be adaptable and applicable across a wider range of use cases [2, 3]. As a result, several paradigms have emerged, such as reconfigurable battery systems [4], software-defined batteries [5], and Heterogeneous Battery Systems (HBS) [6]. These solutions mainly improve the flexibility of battery systems to reduce over-engineering and improve the range of applicable use cases for a given system due to the run-time configuration that can cover a larger range of functional and non-functional requirements that need to be met simultaneously.
