The motor vehicle which comprises a source of propulsion such as electric motor, and a drivetrain system that is used to transfer this energy into the forward movement of vehicles, is known as an electric powertrain. Environmental aspects, socio-economic factors, resilience, energy efficiency, cost of recharging, stabilization of the grid, and heating of electric vehicles are some of the advantages of electrical vehicle power trains. They have very good power-to-weight-ratios as they do not carry heavy internal combustion engines. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail in this book. It presents the complex subject of electrical vehicle powertrains in the most comprehensible and easy to understand language. This book is an essential guide for both academicians and those who wish to pursue this discipline further.
