BATTERY MANAGEMENT SYSTEM FOR ELECTRIC VEHICLES

Abstract

Energy storage options that are adaptable, controllable, and more effective have boosted interest
in electric cars. Electric cars would have a driving motor that was powered by a large battery pack. It's
important to comprehend the battery's power density, endurance, flexible electrochemical behavior, and
temperature tolerance. Electric cars and renewable energy storage systems both require battery management
systems. The study discusses issues, challenges, and battery-related solutions. The battery management
system includes temperature management, battery data actuation and storage, voltage and current
monitoring, charge and discharge estimates, protection, and equalization. The different cell balancing
circuit types, their components, current and voltage stresses, control reliability, power loss, efficiency, size,
cost, and their advantages and disadvantages were also described in this study. Second, we discuss battery
management system issues and difficulties. We also point out issues and challenges that require further
attention if battery management systems for electric cars and renewable energy storage systems are to be
optimum and sustainable.
