In the quest for sustainable transportation, electric vehicles (EVs) are emerging as a prominent solution in terms of reduced emissions, energy efficiency and lower maintenance requirements. However, critical concerns persist regarding safety and range limitations of these vehicles. Therefore, the development of a system aimed at addressing these issues is deemed necessary. This master thesis endeavors to design and develop a new concept of a Battery Management System (BMS), a crucial and essential system that typically performs advanced tasks to ensure optimal efficiency and management, thereby extending the battery life and driving range of EVs. Firstly, the basics of the most common EV architectures are introduced, with a specific focus on Battery Electric Vehicles (BEVs) and their Energy Storage Systems (ESS) technologies, topologies, and compositions.
