A Review of Battery Management System and Modern State Estimation Approaches in Lithiumion Batteries for Electric Vehicle

Electric Vehicle (EV) technology has groomed the automotive industry and is becoming a more reliable source of mass transit. These battery-based vehicles are performing extraordinarily in developing pollution-free environment and better ecological surroundings. Battery Management System (BMS) is the backbone of the EVs that can undoubtedly increase the performance, operation, safety and lifetime of a vehicle’s battery or storage system. Li-ion batteries are performing outclass to provide a more sophisticated storage system for EVs. They have better characteristics than lead-acid or other types of batteries, hence being highly utilized in EV applications. This paper presents the comprehensive review of the BMS for the EV’s. It gives a detailed overview of the Battery Management System (BMS) for the EVs and detailed study of important aspects which comes under consideration during management of batteries. It further provides key factors and extrinsic issues e.g., battery modeling, state estimations and validation profiles etc. which are troubling in the proper and safe operation of the batteries in EV’s, and the algorithms and schemes designed and proposed for their betterment are presented.
