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.
