The reality of the EV shift with respect to internal combustion engines and electrification technologies is a concern these days.

As the trend toward carbon neutrality in mobility continues, the EV shift has become an important topic that engineers involved in powertrains cannot overlook.

Originally, the term “EV” referred to 100% battery-powered vehicles such as BEVs and pure EVs, but as HEVs, PHEVs, and FCVs become available on the market, the term “EV” is increasingly used to refer to all electric vehicles in a broad sense, including these. In this article, “EV” is defined as “100% battery-powered vehicle.

This article looks at both EVs and internal combustion engines, and delves deeply into current trends and technological issues from a neutral perspective. It will also be necessary to consider the future technological outlook by examining the need for more efficient internal combustion engines and the need for carbon-neutral fuels.

What is the background and current status of the EV shift? We will also examine the circumstances that are driving the shift to EVs and those that are hindering the shift, sort out the technical issues (cruising range, charging technology, battery recycling, etc.) that need to be addressed in order to popularize EVs, and not forgetting the need for CN internal combustion engines to support the expansion of the market for sustainable electric vehicles.
