Open North American Charging Standard

Tesla Team November 11, 2022

With over a decade of use and 20 billion EV charging miles under its belt, the Tesla Charging Connector is the most proven in North America, offering AC charging and up to 1MW DC charging in a slim package. It has no moving parts, is half the size and twice as powerful as Combined Charging System (CCS) connectors.

In pursuit of our mission to accelerate the global transition to sustainable energy, today we open our EV connector design to the world. We invite charging network operators and car manufacturers to install the Tesla Charging Connector and Port, now called the North American Charging Standard (NACS), on their equipment and vehicles. NACS is the most common charging standard in North America: NACS vehicles outnumber CCS, and Tesla's supercharging network has 60% more NACS stations than all CCS-equipped networks combined .

Network carriers already have plans in the works to integrate NACS into their chargers, so Tesla owners can expect to charge on other networks without adapters. Likewise, we look forward to future electric vehicles incorporating NACS design and charging on Tesla's North American supercharging and destination charging networks.

As a purely electrical and mechanical interface independent of use case and communication protocol, NACS is simple to adopt. Design and specification files are available for download, and we are actively working with relevant standards bodies to codify Tesla's Charging Connector as a public standard. Enjoy.
