Direction of Powertrain Technology for CASE Deployment in Railway Vehicles

Abstract

CASE (Connected, Autonomous, Shared & Service, and Electric) must be recognized as a comprehensive technology resulting from the rapid progress achieved in the field of automobiles, in terms of development and introduction of the newest technologies. It is also a fact that these individual technologies were incorporated into the railway vehicle sector from a relatively early stage. In automotive industry now, the key to realizing fresh value from CASE lies in EVs (Electric Vehicle). This paper first introduces the CASE technologies that have already been applied to railway vehicles. Then these technologies are compared with the latest advances emerging from the development of EV automobiles, in order to understand the nature of these changes in relation to on-vehicle powertrain and power electronics equipment. Finally, the technical aspects of these changes are outlined.
