Design and Performance Analysis of an Electric Vehicle Using Matlab

Conventional vehicles utilize petroleum derived fuels to provide good performance and long-range. But conventional vehicles have certain disadvantages such as high fuel cost and exhaust gas emission causing environmental pollution. So, to overcome these disadvantages, electric vehicle technology is useful. An electric vehicle is modeled using matlab tools. The model mainly consists of a vehicle body, motor, motor controller unit and a battery block. The motor control unit regulates the speed of the motor which in turn controls the speed of the vehicle so that the actual speed matches with the reference speed given to the longitudinal driver block. The longitudinal driver block provides the PI control and ensures the closed loop operation. It is is divided into two parts, in the first one, vehicle body dynamics are examined for wind & terrain constants, brakes changes and gear shifts with ideal sources and PWM controlled DC motor. In the second part, 4 wheeler and 2 wheeler are designed for which reference and actual speeds are compared in the scope and battery SOC, distance traveled are tabulated.
