Hi @Irfan Amin Gadai
That probably implies one thing: the dynamics modeling for your Electric Vehicle is incorrect.
Check your model in Simulink with various references, i.e., books, journal papers, etc.

Chapter 8 is on Electric Vehicle Modelling. Check the equations that you needed to to predict is the EV performance range.

Thank you for your reply but after consulting with my prof, he said i have to check the block parameters and thats where the problem was.. but there is still one problem i.e the velocity does not exceed 2 km/hr
