Tesla is sharing the design of its EV charging connector in an effort to encourage network operators and automakers to adopt the technology and make it the new standard in North America.
tesla said: in a blog post Friday that the design and specification files are available for download. The company said it is “actively working with relevant standards bodies to codify Tesla’s charging connector as a public standard.”
The charging connector in all Tesla vehicles provides AC charging and up to 1 MW DC charging. Its compact design and performance is considered superior to the Combined Charging System connectors used by most EVs in North America.
Tesla claims that its charging connector and charging port — which it now calls the North American Charging Standard (NACS) — is the most common charging standard in North America. It’s a metric based on Tesla vehicle sales in North America and the number of chargers at the brand’s Supercharging stations. Tesla has nearly 1,500 Supercharger stations in the United States. Each station has an average of nine chargers.
Tesla did not name automakers or charging infrastructure companies as converts. In this highly competitive environment, where virtually every automaker is now using the CCS, it’s hard to see GM, Ford and Stellantis adopting Tesla’s technology.
At least one company — EV startup Aptera — is supporting the move. Earlier this year, Aptera called on the US government to adopt Tesla’s Supercharger technology as the standard for all EV charging in the country. And EVGo has Tesla connectors added to some of its charging stations in the United States.
The company said in the blog post that network operators “already have plans in progress” to integrate NACS into their chargers. If carriers like ChargePoint, EVConnect or Electrify America add NACS, Tesla owners could charge at these stations without needing an adapter.
If automakers move to the NACS on their EVs, owners of those vehicles would gain access to Tesla’s North American Supercharging and destination charging networks.
