DETROIT – The North American Charging Standard plug, also known as NACS, SAE J3400, or by its original name, the Tesla plug, is quickly becoming the default charging plug in the U.S. and Canada. It is replacing the J1772 and CCS1 plugs, which were used on most EVs other than those of Tesla, Nissan, and Mitsubishi for charging.

Tesla’s Charging Plug Begins World Takeover

Every one of Tesla’s Supercharger stations uses it, as it has been the Tesla plug since the first Model S in 2012. Tesla’s extensive network means there are more Level 3 stations using that plug than any other. Other automakers began announcing in early 2023 that they would start adding the plug to their cars. Adapters started showing up in 2024, and OEMs started installing NACS ports in their EVs late last year, reports Car Buzz. 

Mazda said it is adding NACS in Japan “to provide customers with greater convenience by a broader range of charging options.” It will let Mazda’s EV owners use Tesla Superchargers in Japan. They will also support other charge standards in that country with adapters.

Move Could Boost Mazda EV Prominence

In the U.S., Mazda was one of the last automakers to announce it would adopt the NACS charge plug. It still does not offer it on its CX-70 and CX-90 PHEV models, though it is anticipated to be coming in the next few years. While Mazda said it will add NACS to all EVs introduced in the US from 2025 onward, it’s not clear when Mazda will launch an EV in the U.S. The short-lived MX-30 EV was discontinued in 2023 after less than two years of sales.

While Mazda is behind in the U.S. on both EVs and NACS, this could be a big turnaround for the brand and put it at the head of the curve at home. Aside from Tesla, only one other automaker has announced plans to use NACS. That’s Sony Honda Mobility, which said its Afeela EVs would use the standard. Though that vehicle is still not on sale anywhere in the world.

It is anticipated in the U.S. later this year, but it’s not clear when the U.S.-built model might be sold in Japan.

That could make Mazda the first non-Tesla automaker to use NACS in Japan. A big deal for it and for the plug. The brand currently offers the MX-30 as its only EV in Japan, though it has an electric sedan called the EZ-6 on sale in China. It is expected to deliver an in-house electric SUV for Japan in 2027, which would be the first with the new plug.
