Abstract

Electric Vehicle (EV) charging methods have evolved over the past two decades to reflect the radical evolution of EVs. In some cases these methods have been of varying usefulness to the EV driver. DC fast charging, which made a brief appearance in the late 90s, is now a valuable EV market enabler, but suffers from the political and technical disagreements of multiple protocols. Globally, EV charging will evolve further to meet the demands of the new consumer EVs and the demands of the EV driver. This paper proposes an integrated global philosophy to meet these demands.

Highlights

  • The focus here will be on the needs of the Electric Vehicle (EV) driver and what the EV charging picture will look like to meet those needs

  • While this model has been sufficient to support the latest push for modern EVs, such low power charging doesn’t allow for OEMs to push the limits on reducing charge time or increasing range which would better suit the needs of more drivers

  • In-trunk cordsets serve the basic need of the EV driver to have a portable charger available when they’re both home and away and don’t have access to a public charger
