The industry-wide move to mass adoption of all-electric vehicles is far from sorted, with one of the big questions being the standardization of electric vehicle plug types. One of the most popular is the North American Charging Standard, or NACS, developed by Tesla. GM recently announced it would adopt the NACS standard starting in 2025. Now, however, the White House has stated that in order to be eligible for billions of dollars in federal subsidies, the NACS-based Tesla Supercharger Network would also need to be compatible with a competing plug type, specifically the Combined Charging System, or CSS.
Per a report from Reuters, a White House spokesperson has weighed in on the competing plug type standardization efforts.
“Earlier this year, we developed minimum standards to ensure publicly funded EV charging is accessible, reliable, and affordable for all drivers, and we required interoperability to promote competition,” said White House spokesperson Robyn Patterson in a statement to Reuters. “Those standards give flexibility for adding both CCS and NACS, as long as drivers can count on a minimum of CCS.”
Patterson also said that every EV should eventually be able to connect to any publicly funded charger, adding that “More drivers having access to more high-quality charging – including Tesla Superchargers – is a step forward.”
Just last week, GM announced that it would adopt NACS in new GM EVs starting in 2025. The announcement coincided with news that GM was partnering with Tesla to provide GM EV owners with access to more than 12,000 Tesla Supercharger stations throughout North America, starting in early 2024. GM’s crosstown rival, Ford, made a similar announcement, and also plans to equip future EVS with an NACS port.
Notably, GM EV owners already have access to 134,000 chargers through the Ultium Charge 360 initiative and mobile apps, which includes CCS plugs. Moving forward, GM says it will make adapters available for NACS-enabled vehicles at CCS-capable fast charge stations.
