EV Charging Connectors Explained: CCS vs Type 2 vs CHAdeMO vs Tesla/NACS (2026)

📅 Published on 12 February 2026

If you're new to electric driving, the number of plug types can be confusing at first. Every charging station lists a connector type, and if you don't recognize it, it's hard to know whether you can actually use that station. Here's a practical, no-nonsense guide to every connector you'll actually encounter on the road in 2026, plus what adapters can and can't fix, so you can plan with confidence.

The connectors you'll actually see

Type 2 is the standard AC connector across Europe, used for slow and normal charging (up to 22 kW) at home, at work, and at public normal-speed stations. Almost every new EV sold in Europe supports it, which makes it the connector you'll see most often in parking garages, supermarkets, and residential streets. It's a round plug with a flat top, and it typically takes anywhere from 4 to 10 hours to fully charge a car, depending on battery size and available power.

CCS (Combined Charging System) combines a Type 2 plug with two extra pins below it for DC fast charging, delivering up to 350 kW at the fastest stations. This is the dominant fast-charging standard in Europe and is increasingly adopted in North America as well. If you're planning a long road trip, CCS stations are what you'll rely on for a 15-30 minute top-up instead of an hours-long wait.

CHAdeMO is an older DC fast-charging standard, mainly used by older Nissan Leaf and Mitsubishi Outlander PHEV models. Fewer new charging stations are being built with CHAdeMO support these days, since the industry has largely moved toward CCS, so if your car relies on CHAdeMO, it's worth checking availability along your route before you set off.

Tesla connectors vary by region: newer Teslas sold in Europe ship with a standard CCS port, meaning they can charge at any CCS station just like other EVs. North American Teslas, on the other hand, have historically used Tesla's own proprietary NACS plug, though this is changing rapidly as other manufacturers adopt NACS too. If you drive a Tesla, always double-check which connector your specific model and region uses.

NACS (North American Charging Standard) is Tesla's own connector, now adopted by most major automakers in North America and standardized as SAE J3400. In the US and Canada, NACS increasingly appears alongside or instead of CCS1 at charging stations, and by 2026 most new non-Tesla EVs sold in North America ship with a native NACS port rather than needing an adapter.

GB/T is China's national charging standard, used by the vast majority of EVs sold there, which makes up the largest share of EVs on the road worldwide. GB/T uses separate connectors for AC and DC charging and is not physically compatible with CCS or Type 2. A next-generation connector called ChaoJi, developed jointly by China and Japan's CHAdeMO consortium, aims to eventually replace both GB/T and CHAdeMO with a single ultra-fast standard, though the rollout remains gradual as of 2026.

In markets like India, you'll often see the connector referred to as CCS2 rather than just "CCS" - it's the same DC fast-charging standard used in Europe, paired with Type 2 for AC charging.

Connectors at a glance

Adapters: what they can and can't fix

Adapters bridge a physical connector mismatch, but they don't add capability your car doesn't have. A Tesla-to-CCS adapter (or the reverse, for non-Tesla cars using Tesla Superchargers) lets the plug fit, but your charging speed is still capped by whichever side has the lower limit - car, cable, or station. CHAdeMO-to-CCS adapters exist but are rare and expensive, and most drivers relying on CHAdeMO are better off simply route-planning around CHAdeMO-capable stations rather than hunting for an adapter. GB/T-to-CCS adapters are uncommon outside China and generally not something to plan a trip around.

Why the connector alone doesn't tell you the charging speed

Matching connector shapes only tells you the plug will physically fit - it says nothing about how fast you'll actually charge. AC charging speed is capped by your car's onboard charger (commonly 7.4, 11 or 22 kW, sometimes lower on older or budget models), not by the wall connector's theoretical maximum. DC fast-charging speed is capped by your battery's chemistry, temperature, and state of charge - a "350 kW-capable" station will still only deliver what your specific car's battery can accept at that moment, which is often far lower, especially above 80% charge or in cold weather. Always check your vehicle's actual charging curve rather than assuming you'll get the station's advertised peak number.

Frequently asked questions

Can I use a CCS adapter on any Tesla?

Only on models built with the hardware to support it (typically CCS-native in Europe already, or NACS-to-CCS adapters for North American Teslas visiting a CCS station). Check your specific model and region before assuming compatibility.

Is CHAdeMO disappearing?

Effectively yes for new infrastructure - very few new public chargers are being built with CHAdeMO connectors in 2026, though existing ones remain in service. If your car depends on it, verify availability on your route rather than assuming coverage.

Will NACS fully replace CCS in North America?

It's heading that way - most major automakers have committed to NACS, and many new non-Tesla EVs already ship with a native NACS port. CCS1 infrastructure will remain usable for years via adapters, but new stations increasingly prioritize NACS.

Why did my car charge slower than the station's maximum kW?

Because the station's number is a ceiling, not a guarantee - your actual speed depends on your battery's charging curve, current state of charge, and temperature, all of which typically matter more than the station's headline figure.

Getting the wrong connector type wrong isn't just inconvenient, it can mean driving out of your way for nothing. In Elunio, you can filter search results by exactly the connector type your car needs, so every station you see in your results is one you can actually plug into. Combined with real driving distance instead of straight-line estimates, this makes trip planning far less stressful.
