CCS1
Combined Charging System 1
The fast-charging plug on most non-Tesla EVs in North America, and South Korea's national standard. New cars are moving to NACS, but CCS1 chargers are still being added.

You drive a non-Tesla EV from before 2025
Most non-Tesla EVs sold in North America since the mid-2010s have a CCS1 port, and so do many 2026 models, including most of GM's lineup, the VW ID.4 and the BMW i4. You fast-charge on CCS1 and charge at home through the same port.
Your new car has a NACS port
Models like the 2025 Hyundai Ioniq 5 and 2026 Toyota bZ use NACS. You can still use CCS1 chargers with an adapter sold as "CCS to NACS". Check what your automaker supplies or approves.
You're driving outside North America
South Korea uses CCS1 as its national standard, and it is Taiwan's main public fast-charging plug for non-Tesla cars. Europe uses CCS2, which a CCS1 car can't plug into.

One port for home and fast charging
A CCS1 inlet is the J1772 (Type 1) AC inlet with two large DC pins added below it, seven contacts in all. A Level 2 charger's J1772 plug fills the top half. A DC fast charger's CCS1 plug fills the whole inlet and leaves J1772's two AC pins unused.
AC through the J1772 half tops out at 19.2 kW (80 A at 240 V). NACS also carries AC and DC through one inlet, and adapters connect the two in both directions.

350 kW top class, 200 kW at a typical US port
CharIN's top CCS power class is 350 kW. US public CCS1 ports have a median listed rating of 200 kW, and a third are listed at 350 kW or more. A charger never delivers more than the car accepts, so your car's own peak rate sets the real speed.

Where you'll find CCS1
North America and South Korea are the strongholds, and it is Taiwan's main public DC plug for non-Tesla cars. Europe uses CCS2, which a CCS1 car can't plug into.

From a 2011 alliance to the NACS switch
Seven automakers presented CCS in October 2011, and SAE published the combo plug a year later. From 2013 it spread across North America's non-Tesla EVs and became South Korea's standard. Since 2023, automakers have been moving new North American models to NACS.

Seven automakers back CCS
Audi, BMW, Daimler, Ford, GM, Porsche and Volkswagen present the combined system in Germany.
- Oct 2012
SAE publishes the combo plug
The J1772 standard gains two DC pins, so one port handles AC and DC.
- 2013–2024
North America's non-Tesla plug
From the BMW i3 and Chevrolet Spark EV on, most non-Tesla EVs sold in the US and Canada use it.
- Jan 2018
South Korea moves to CCS1
The standards agency plans to revise the national standard to recommend CCS. 67% of Korean EVs already used CCS in 2017.
- Nov 2022
Tesla opens its plug as NACS
SAE standardizes it as J3400, publishing a first version in December 2023.
- May–Jun 2023
Ford and GM commit to NACS
Both plan NACS ports from 2025. Most other automakers follow for North America.
- 2025
The network still grows 46%
US public CCS1 ports rise by 9,895 in the year, to about 31,350.
- Aug 2026
GM goes all-NACS
Every GM EV gets a native NACS port from model year 2027.
What catches people out
CCS1 is not CCS2
Chargers and adapters labeled just "CCS" can mean either. CCS2, used in Europe, has a different AC section and won't fit a CCS1 car. Check the number before you buy an adapter or plan a trip abroad.
Adapter names run both ways
For a CCS1 car at a Supercharger you need the adapter sold as "NACS to CCS". A "CCS to NACS" adapter does the opposite: it lets a NACS car, like a 2025 Ioniq 5, use a CCS1 charger.
Not every Supercharger works
Adapters work only at V3 and V4 Superchargers, and only if your automaker has Supercharger access. The Tesla app can start the session. Use one that is UL 2252 certified and approved by your automaker.
Tesla AC chargers need another adapter
The Supercharger adapter is DC only. Tesla Wall Connectors and destination chargers need a separate NACS-to-J1772 adapter, which plugs into the J1772 half of your port.
Own a CCS1 car? These fill the gaps
Your car charges at home through the J1772 half of its port, and it needs adapters to use Tesla's chargers. These are the pieces worth owning.

Questions
What is CCS1?
The Combined Charging System connector used by most non-Tesla EVs in North America, and South Korea's national DC standard. It is the J1772 AC plug with two DC pins added, so one port handles home and fast charging. Its top CharIN power class is 350 kW.
Can a CCS1 car use a Tesla Supercharger?
Yes, at V3 and V4 Superchargers, if your automaker has Supercharger access. You need an adapter sold as "NACS to CCS" that is UL 2252 certified and approved by your automaker, and the Tesla app can start the session. Tesla's AC chargers need a separate NACS-to-J1772 adapter.
Is CCS1 being phased out?
Not at the charger. US public CCS1 fast-charging ports rose 46% in 2025, and the federal station database listed 38,899 in October 2026. The change is in new cars: most automakers are moving North American models to NACS, and GM's whole lineup switches for model year 2027.
