EV connector types: how to read the labels
Each connector chip in the list is a plug type with a count and, when mapped, the highest power in kW, such as “CCS1 (Combo 1) ×4 · 150 kW”. This page explains only the labels, taken from the OpenStreetMap socket tags.

The labels and the tags behind them
The descriptions are the OpenStreetMap wiki’s own, shortened. The countries are where the wiki says each plug is common, not a rule about which car can use which charger.
On a narrow screen, swipe the table sideways to read every column.
| Label in the list | OpenStreetMap tag | What the wiki says | Common in |
|---|---|---|---|
| J1772 (Type 1) | socket:type1 | IEC 62196-2 Type 1 / SAE J1772 plug, AC: Level 1 at 120 V or Level 2 at 240 V. | United States, Canada |
| CCS1 (Combo 1) | socket:type1_combo | A J1772 plug with two larger extra pins for DC fast charging. | United States, Canada |
| Type 2 | socket:type2, socket:type2_cable | IEC 62196-2 Type 2 plug (“Mennekes”), AC. | EU, UK, Norway, Iceland, Australia |
| CCS2 (Combo 2) | socket:type2_combo | A Type 2 plug with two larger extra pins for DC. The wiki says this tag includes CCS at Tesla Supercharger stations. | Australia, EU, Iceland, Norway, UK (as for Type 2) |
| CHAdeMO | socket:chademo | A Japanese DC fast-charging standard (IEC 62196-2 Type 4). | Japan, United States, Canada, EU, UK, Australia, Iceland |
| NACS (J3400) | socket:nacs | The North American Charging System plug for AC and DC, standardized as SAE J3400. | United States, Canada, Mexico, Japan, South Korea and others |
| GB/T AC, GB/T DC | socket:gb_ac, socket:gb_dc | The Chinese national standard plugs for slow (AC) and fast (DC) charging. | China (GB/T AC also Belarus, Russia) |
| Tesla (old tag) | socket:tesla_supercharger and similar | The wiki tells mappers not to use these values and to use nacs, type2 or type2_combo instead, so old data may still carry them. | Older mapping |
What “×4” and “150 kW” mean
The number after the × is the count the mapper entered for that plug type: how many can be used at the same time. When the tag only says “yes”, the plug is present and the count is not shown. If a station lists two counts, such as 6;3, the page adds them.
The kW is the highest output listed for that plug type at that station. A plain number means kilowatts, and watts and megawatts are converted. It is what the charger can deliver at most. Your car may charge slower, and a station shared between several plugs may split its power.
A label the page does not recognise is shown as the raw OpenStreetMap key, for example “type3a”, instead of being hidden. Household sockets (Schuko, NEMA) appear when a mapper has listed them on a charging station.
Which connector does my car need?
This page does not answer that, on purpose. The answer depends on your car, its region and sometimes an adapter. The sister site Charge Travel has a full guide built from official sources: EV connector types on Charge Travel. When you know the plug, look for it in the list on the finder, and treat a station with “Connectors: not listed” as unknown rather than as compatible.
Questions people ask
What do CCS1 and CCS2 mean in the list?
They are the OpenStreetMap tags type1_combo and type2_combo. CCS1 is a J1772 plug with two extra DC pins, common in the United States and Canada. CCS2 is a Type 2 plug with two extra DC pins, common in Europe.
What is NACS?
NACS is the North American Charging System plug, standardized as SAE J3400, used for AC and DC charging. The list shows it as “NACS (J3400)” when the station has the nacs tag.
Why does a station show “Connectors: not listed”?
Nobody has added the socket tags for it on OpenStreetMap. The station may have any plug. Check the operator before you go.
Is the kW the speed my car will charge at?
No. It is the highest output listed for the plug. Your car’s maximum, the battery level, the temperature and other cars on the same station all change the real speed.
Why do some stations list an old Tesla tag?
Older edits used Tesla-specific values that the OpenStreetMap wiki now tells mappers to avoid. The list shows them as “Tesla (old tag)” rather than guessing which modern plug they meant.
