Simulation study of a battery management system for electric vehicles using MATLAB/Simulink.

The overconsumption of fossil fuels has drastically increased the emissions of toxic gases causing harm to the environment. Batteries are one of the most important components of Electric Vehicles. When dealing with bigger capacities and high power requirements, high power supplying battery packs are required, which consist of several batteries. These high capacity battery packs are prone to reach high temperatures during charging and discharging thus, giving rise to a lot of complications. Hence, the use of a battery management system is essential. It is responsible to optimize the battery pack which results in better and safer working of the battery pack. The main objective of this paper is to simulate a MATLAB/Simulink model of a Battery Management System (BMS) and analyze the different types of estimation methods of the main parameters of a battery management system. It also provides an idea on the most efficient and cost-friendly methods to implement in a BMS. The main parameters include the balancing of the battery pack, state of charge (SoC) estimation methods, state of health (SoH) estimation, charging and discharging control and temperature monitoring, which help improve the performance of the battery.
