In 2025, the expansion of DC fast-charging infrastructure was particularly intense amid the transition from the CCS1 to the NACS (SAE J3400) charging connector standard.
According to the Alternative Fuels Data Center (AFDC), the total number of public DC fast-charging connectors in the US was 67,916 as of January 1, 2026. That’s an increase of almost 17,000 (or 33%) year over year. The number of locations increased by more than 2,200 (or 18%) to 14,623.
Interestingly, over the past 12 months, deployment of CCS1 chargers outpaced NACS (SAE J3400) chargers, despite the fact that the entire industry is switching to SAE J3400.
CCS1: +10,000; NACS: +8,000
The AFDC’s data indicates that between January 1, 2025, and January 1, 2026, the number of CCS1 connectors increased by 9,895 or 46%. That’s a very fast growth rate, especially for a standard that will be retired in North America.
Meanwhile, during the same period, the number of NACS (SAE J3400) connectors increased by 7,924 or 27%. The growth is noticeably slower.
We assume that the reason for the difference is the strong push for CCS1 by the general EV industry, with many large projects initiated before the switch from CCS1 to NACS (SAE J3400) was announced. Additionally, general networks were installing chargers primarily for non-Tesla EVs, equipped with CCS1 charging inlets. The NACS chargers were deployed mostly by Tesla itself (+6,599 Superchargers and + 1,785 non-Tesla NACS connectors).
The third DC fast-charging standard — CHAdeMO — was retired several years ago, resulting in a negligible decrease in the number of connectors. We can say that it had a flat year. It’s very likely that no one is installing CHAdeMO chargers anymore. There are no new EV models with the CHAdeMO charging port.

Looking forward, it’s very likely that in 2026 or no later than 2027, the NACS (SAE J3400) deployment will outpace CCS1 deployment. The CCS1 might still receive a noticeable number of new chargers, but it’s expected to gradually weaken and begin to fade at some point during the next decade.
The CHAdeMO is already advancing on its way out. New installations are rare, so once the chargers age, they will be gradually removed without replacement.
Currently, more and more EV models are equipped with NACS charging ports.
Market Share
The year 2026 began with almost 37,500 NACS (SAE J3400) DC fast-charging connectors, over 31,350 CCS1 connectors, and less than 8,900 CHAdeMO connectors.
The major push for CCS1 enabled it to increase its market share to 40.4%. That’s a substantial gain compared to 35.8% at the beginning of 2025. Just imagine what could have been if there had been no switch from NACS to CCS1 (the avalanche started by Tesla and Ford). The CCS1 would be growing faster than the NACS used solely by Tesla.
The market share of NACS (SAE J3400) amounted to 48.2%, down from 49.3% a year ago. However, that’s a minor decrease, and ultimately the standard is poised to reach 100% for light-duty EVs.
Meanwhile, CHAdeMO is losing ground rapidly, with its share declining from 14.9% a year ago to 11.4%. Moreover, these are usually low-power chargers.

68,000 DC Ports
The number of publicly available DC fast-charging connectors of all three standards (NACS, CCS1, and CHAdeMO) exceeds 77,700. However, not all connectors can be used simultaneously. The number of simultaneously available DC fast-charging stalls (or ports) is estimated at only about 68,600.
*An EV charging port provides power to charge only one vehicle at a time, even though it may have multiple connectors. The number of individual connectors might be equal to or higher than the number of ports.
