Bhuvaneswari, R.2025-02-272025-04-012025-02-272022-03-29https://doi.org/10.1109/iccmc53470.2022.9753907https://dspacenew8-imu.refread.com/handle/123456789/2676A system for battery management is vital in reliable and safe battery operation. They are being extensively applied in high power applications, hybrid electric vehicles, and many more arenas to ensure intermittent power supply. The paper aims at providing a detailed study of the different batteries available in the market and their efficacy when exposed to different environments. The main parameters taken into consideration are the service life, nominal voltage, charging and discharging rates, and temperatures. Firstly, types of battery modeling are studied comprehensively followed by various batteries used in the industry for EVs and Power system applications. Various battery models such as electrical, thermal, and coupled electrothermal model are discussed. Subsequently, the battery condition estimates for the charging state, health estimation, and internal temperature are extensively studied. Then, the major types of battery modeling along with traditional battery charging and optimization techniques are presented with necessary equations and simulation proofs. The practical results implemented are also presented for reference.enBattery modelingBMS (Battery Management Systems)Battery State EstimationEV (Electric Vehicle)Article
