Electric Vehicle Powertrain - Calculations and Mathematical Modelling
All about Powertrain Powertrain is a crucial component in any vehicle. In this blog we will talk about electric powertrain design. Everything will be seen in the perspective of E2W on asphalt. We will also see a case study of ATHER 450X, A beast work of electric powertrain by Ather Energy. Longitudinal Forces acting on a vehicle: Source: https://drive.google.com/file/d/17VwUjuRfPLB-W0KXfy3djaeNOFBNMRe2/view?usp=sharing Rolling Resistance: A force that opposes the motion of an object. This is the force acting on the vehicle due to tire properties called hysteresis.
