The EV Battery Management System is mainly in charge of monitoring the parameters of the battery. The analogue front end gathers data to determine battery health. This improves an electric vehicle’s performance. The cell balancing circuit in the BMS ensures that each cell has the same level of discharge and charge so that some cells are not swamped and destroyed. Balancing the charging and discharging of individual cells improves the electric vehicle’s overall performance, operation, and safety. The BMS also makes it easier to communicate data to the driver. The EV Battery Management System can also be used to monitor the diagnostics and performance of the electric vehicle, as well as to set system parameters.
