TECHNICAL FIELD
Generally, the present disclosure relates to a method to identify master battery. Particularly, the present disclosure relates to the method to identify master battery for swapping stations.
BACKGROUND

As more industries and consumers shift towards sustainable energy solutions, batteries are becoming essential for powering devices, vehicles, and homes. Technological advancements have also led to more efficient and affordable battery designs. The widespread application of batteries is accelerating battery usage across various sectors.
Recently, the usage of a rechargeable batteries is increased which is driven by the global shift towards sustainability and reducing reliance on fossil fuels. Electric vehicles (EVs) are a key contributor in increasing demand for high-capacity rechargeable batteries. The rechargeable batteries in vehicles, primarily lithium-ion types, are utilized to store and supply electrical energy for propulsion and auxiliary systems. These batteries feature high energy density and allowing for extended range and efficiency in electric vehicles (EVs). In electric vehicle battery packs, multiple cells are connected in parallel to form modules, which are then combined to create a larger battery pack. Each module typically includes its own Battery Management System (BMS) to monitor and manage parameters such as voltage, temperature, and state of charge. The multiple BMS for multiple modules ensures localized control and improves safety. Similarly, a battery swapping stations are facilities to exchange the depleted electric vehicle battery with charged battery. The battery swapping stations significantly eliminating the need for extended charging times. Furthermore, multiple batteries of electric vehicles at a swapping station are charged simultaneously, specifically those with varying State of Charge (SOC) levels. In the battery swapping station, each battery has its own BMS to detect to monitor and manage parameters such as voltage, temperature, and state of charge.
However, the issue arises because each BMS in cell modules and in battery packs may report different values, leading to conflicting data when managing the entire cell modules and battery pack. For example, one BMS may signal that the module is fully charged, while another indicates a lower charge level. This fluctuation in BMS signal creates difficulty in determining which values should guide overall decisions, such as when to stop charging or regulate cooling. Such discrepancies may result in inefficient power distribution, imbalanced charging, and potential thermal management failures, thereby increasing wear on the battery pack. Moreover, a centralised control entity is required to manage the charging discharging for the whole system in combination with the individual modules.
Therefore, there is a need to provide an improved battery management system that overcomes one or more problems as set forth above.
