Battery Management System for V2G and G2V in DC Fast Charging Architecture

Electric vehicle (EV) integration with the smart grid has received a lot of attention recently, and has prompted the development of the Vehicle-to-Grid (V2G) and Grid-to-Vehicle (G2V) technologies. Micro-grids may be able to employ the batteries from electric cars (EVs) as a part. A battery management system (BMS) is necessary to enable V2G and G2V to ensure safe and effective operation. A BMS for DC fast charging architecture that can support both V2G and G2V applications is proposed in this study. In order to manage the flow of electricity, the BMS communicates with the smart grid and employs a combination of hardware and software to control the battery's charging and discharging. In fast-charging applications, the ability to optimize battery state of charge and shorten charging time is crucial. The present simulation findings demonstrate that the suggested BMS can boost the charging system's efficiency and dependability, resulting in better battery performance and longer battery life.
