The move means that Rivian owners will soon be able to top up their vehicle’s battery at more than 12,000 Tesla Superchargers across the US and Canada. Rivian plans to keep expanding its Adventure Network of DC fast chargers too.

“The adoption of the North American Charging Standard will enable our existing and future customers to leverage Tesla’s expansive Supercharger network while we continue to build out our Rivian Adventure Network,” Rivian CEO RJ Scaringe said in a statement. “We look forward to continuing to find new ways to accelerate EV adoption.”

Last year, Tesla said it would open source the NACS, which has taken strides toward becoming a true standard for EV charging in North America. Ford, GM and now Rivian are all embracing it as part of an apparent move away from the Combined Charging System (CCS). In November, Tesla pressed its case for the NACS, noting that the breadth of the Supercharger network meant that standard had far wider availability than CCS. The automakers’ shift toward NACS could pressure the likes of Electrify America and Chargepoint to adopt it in their infrastructure too.
