Battery driven electric vehicle matlab / Battery-Driven Electric Vehicle Using BLDC Motor in MATLAB/Simulink / 
 
This MATLAB/Simulink model presents a battery-driven electric vehicle system using a BLDC motor drive with closed-loop speed and current control. The model is developed to study the performance of an electric vehicle under different operating conditions such as acceleration mode, constant-speed driving mode, oscillation mode, and deceleration mode. It also includes regenerative braking analysis, where the motor operates under negative torque and sends energy back to the battery during braking conditions.
 
The electric vehicle is powered by a 48 V battery system connected to a voltage source inverter, which drives the BLDC motor. Hall sensor signals are used to detect rotor position and generate the inverter switching logic. The controller compares reference speed with actual speed and produces current commands to maintain accurate speed tracking. The simulation clearly shows battery voltage, battery current, state of charge, speed response, torque profile, stator current, and back EMF, making it useful for analyzing EV propulsion and regeneration behavior in detail.
