“…There are two commonly used RBS hardware designs in practice: one is dedicated to a single load, in which each battery has three switches. The other is dedicated to multiple loads with six switches per battery [3]. The increase in the number of hardware leads to an increase in the size, weight and cost of the system.…”

“…This is actually achieved by deploying power switches around the cells and adjusting its connectivity in real time by using the dedicated micro-controller. To understand the state-of-the-art technology development in RBS and useful insights, the authors referred to several review studies [1][2][3]. These studies systematically introduce the various topology designs of RBS [earliest design, series topology and Self-X, genetic framework, 'dependable, efficient, scalable architecture' (DESA), directed acyclic graph etc.…”

“…Moreover, there is a limitation on the effectiveness and efficiency of BMS because of inability to store a large amount of data, poor real-time computational capability and data utilisation, compiling data analytics algorithms, efficient computing of battery states etc. [3]. This results in a series of problems, such as, non-uniform temperature and charge distribution, over-charging, over-discharging etc., and could eventually result in lithium plating, thermal runway and overheating, leading to an explosion/fire.…”

Research on Reconfigurable Battery Systems (RBS) is gaining emphasis over the traditional fixed topology of the battery pack due to its advantages of adapting flexible topology (series‐parallel) during its operation in the pack for meeting the non‐linear time‐dependent load requirements. There could emerge serious issues such as those related to safety due to malfunction of the switching circuit, heat generation from switches during frequent switching of circuits, charging temperature rise, increased charging time, sensing issues arising from the use of low‐accuracy voltage/current sensors, state of charge/state of health estimation, and cost issues due to the use of increasing number of switches, fuses, contactors, relays, circuit breakers etc. To address these mentioned issues, the problem of optimal switching circuit topology for RBS is formulated as a mathematical multi‐objective optimisation problem. An intelligent system framework based on digital twins is proposed. The proposed framework is further extended to a life cycle management approach that includes the interactions among pack design, pack assembly and operational and recycling levels. This could provide greater access of real‐time big data cloud storage to the battery designers, manufacturers and recycling industries, who can make use of it to optimise their designs, systems and operations.
