General Motors has developed a relationship with EV charger builders Delta Americas to build Extreme Fast Charger stations with the capability to add 180 miles of range in just ten minutes. Delta Americas has said they’ll have a final prototype of the XFC station ready by 2020, just in time for GM to finalize its full lineup of electric vehicles, 20 different nameplates, ready by 2023. Adding 18 miles of range per minute of charge dramatically outstrips Tesla’s Supercharger—which currently produces about 6 miles of range per minute—as well as Porsche’s upcoming 350kW system, which promises 12.4 miles per minute. GM’s plan, sponsored by the U.S. Department of Energy, is to use solid-state transformers to deliver 400kW of electricity directly to vehicles with an as-yet-unheard-of 96.5% efficiency rate from the grid to the car. Reaching higher levels of efficiency will be important as electric cars become a more mainstream and popular choice, both in terms of consumer friendliness and in the tax such a charger would place on the nation’s power grid. “We’re thrilled to lead such an important project and have a stellar team of researchers and partners in place that are more than ready to take on the challenge of setting a new standard for EV fast charging,” President of Delta Americas, M.S. Huang, told The Drive. “By utilizing solid-state transformer technology, we have the opportunity to create unprecedented charging speed and convenience that will ultimately help support the DOE’s strategic goal of increasing EV adoption across the… [Read full story]
