Performance Analysis of Electric Car Based on Drag Coefficients and Road Angles

Transportation sector is the largest energy user and we are highly dependable on oil reserves for this purpose. Oil prices are skyrocketing day by day and the oil reserves in the world are diminishing at a faster rate. With the current trend, the global population may increase from 6 billion to 10 billion by 2050. Hence an increase in vehicle numbers adds on to total pollution. Therefore, it is high time to develop a clean and sustainable transportation system. Thus, Electric Vehicles (EVs) are attaining huge importance and will oversee the clean vehicle market. The electric vehicle design approach is multidisciplinary and there are various techniques to evaluate the performance of the vehicles. The paper presents an equation placed strategy to calculate the total tractive power. The various resistive forces acting on a vehicle during uphill condition is considered in order to get the total tractive force. The paper analyses the relationship between the dynamic vehicle parameters and the tractive force requirement of the vehicle. A comparison is provided by varying the aerodynamic drag coefficients and road angles for achieving a particular final velocity. Vehicle dynamic equations are simulated in MATLAB platform.
