A CHAdeMO plug is the big round one. On the car it fits a large circular inlet behind its own door, separate from the smaller socket used for home charging. On the station it is a heavy round connector with a locking latch, on a thick tethered cable, almost always labelled “CHAdeMO”. If the connector face is a full circle, it is CHAdeMO.
Key Takeaways
- CHAdeMO is the full-circle connector, on its own large round inlet, separate from the AC socket.
- The station plug has a locking latch and a thick tethered cable, labelled on the unit.
- CCS is the look-alike to rule out: a J1772 shape with two fat pins below.
- No adapter crosses between CHAdeMO and CCS — check the connector filter first.
On the Car: A Second, Bigger Door
Most EVs have one charge door. A CHAdeMO car has two inlets: the smaller socket for AC charging at home, and a larger round inlet only for DC fast charging. Open the flap and the difference is obvious — the CHAdeMO inlet is a plain circle, wider than the AC socket beside it, with no extra pins below it. Cars fitted with it are mostly earlier Japanese models, and the two-door layout is the quickest way to spot one in a used-car photo. What Is J1772? covers the AC socket it sits next to.
On the Station: The Plug in Your Hand
- A round face. The connector is circular, not the rounded-rectangle shape of AC plugs.
- A latch you operate. CHAdeMO plugs lock mechanically. A lever or release button on the handle unlocks it so you can pull the connector free when the session ends.
- A thick, heavy cable. It is a DC fast-charging cable, fixed to the station — visibly heavier than a home charger’s cable.
- One cable among several. Many DC units carry two or three cables side by side. The CHAdeMO one is the round one; the label on the holster confirms it.
Telling It Apart at a Glance
| Connector | What you see | Where it plugs in |
|---|---|---|
| CHAdeMO | A full circle, plain round face, locking latch on the handle | Its own large round inlet, separate from the AC socket |
| CCS1 | A J1772-shaped top with two large extra pins in a block below it | The car’s combined AC/DC inlet — one socket does both |
| J1772 (AC) | A smaller round plug with a clip on top, no extra pins below | The AC inlet used for home and workplace charging |
| Type 2 (AC, Europe) | A round plug with a flattened top edge | The AC inlet on European-market cars |

Two Mistakes the Visual Check Prevents
Trying to make it fit. A CHAdeMO plug does not go into a CCS inlet, a CCS plug does not go into a CHAdeMO inlet, and no adapter bridges the two DC systems. If the shape is wrong, the answer is a different cable or station, never force. Can You Use Any EV Charging Station? explains what decides compatibility beyond shape.
Assuming every fast charger has one. Newer sites are specified around CCS and NACS, and federally funded U.S. corridor stations must offer CCS1 on their DC ports under 23 CFR Part 680 — CHAdeMO is not required. Before a trip, filter the DOE’s Station Locator by connector so you only navigate to units that carry the round cable.
For Site Operators: Connector Mix Is a Visual Promise
Drivers identify your station by the cables hanging on it. Sites serving older Japanese EVs keep a CHAdeMO cable in the mix; sites specified for current North American cars lead with CCS1 and NACS. EVDANCE’s EV-RHDC30K-L compact DC fast charger delivers 22 kW DC with the connector specified for its market, and our commercial charging solutions outline the options.
Frequently Asked Questions
Could the round inlet be something else?
In North America and Europe, a large separate round DC inlet means CHAdeMO. The exception is market, not shape: cars built for China use the GB/T system, whose DC inlet is also round. On an imported car, check which standard it was built for.
Why does the CHAdeMO plug have a latch?
DC fast charging moves a lot of power, and the connection must stay locked while current flows. The latch holds the connector in the inlet for the whole session and releases only after charging stops.
Do I need my own CHAdeMO cable?
No. The cable is part of the station, as with all DC fast charging. What you need is the matching inlet on the car — without the round inlet, no cable or adapter adds CHAdeMO charging.
