Designing/Selecting Electrical Drivetrain for a vehicle need various criteria has to be taken into account, Criteria such as Power to size ratio and maintaining better efficiency at all range of vehicle speed without affecting vehicle performance. To increase power to size ratio, Split Power Co-Axial Drivetrain which is achieved by connecting two prime motors into a planetary coaxial differential integrated transmission through which we were able to sum up the torque of two motors, also this concept will have added advantage to vehicle range extension and better vibration dampeners.
