Tesla shares the design of its EV charging connector in an effort to encourage network operators and automakers to adopt the technology and help make it the new standard in North America.
Tesla said in a blog post on Friday that its design files and specifications are available for download. The company said it is “actively working with the relevant standards bodies to codify the Tesla Charge Connector as a public standard.”
The charging connector on all Tesla vehicles offers AC charging and DC charging up to 1MW. Its compact design and performance are considered superior to the Combined Charging System (CCS) connectors used by most electric vehicles 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 statistic based on Tesla vehicle sales in North America and the number of chargers at its branded 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 any automakers or charging infrastructure companies as converts. In this highly competitive environment, where virtually every automaker is now using CCS, it’s hard to see GM, Ford and Stellantis switching to Tesla technology.
However, at least one company, the electric vehicle startup Aptera, supports the measure. Earlier this year, Aptera asked the US government to adopt Tesla’s Supercharger technology as the standard for charging all electric vehicles in the country. And EVGo has added Tesla connectors to some of its charging stations in the United States.
The company said in the blog post that network operators “already have plans in place” to incorporate NACS into their chargers. If network providers like ChargePoint, EVConnect or Electrify America add NACS, it would allow Tesla owners to charge at these stations without the need for an adapter.
If automakers switch to NACS in their electric vehicles, it would give owners of those vehicles access to Tesla’s North American supercharging and destination charging networks.
