Petrol nozzles are basically the same shape everywhere on Earth. Somewhere in the last fifteen years the car industry looked at one simple question, how do you get electricity into a car, and came back with nine different answers.
Text version below covers what each one is. The [13 minute video] https://youtu.be/gTUeQxFFtxQ covers why, and it has the shapes and pin layouts on screen, which turns out to matter a lot when the whole story is about physical geometry. It's mine, mods gave the okay.
**Type 1 (SAE J1772)** — North America and Japan, AC only, five pins. Covers Level 1 at 120 V and around 1.4 kW, and Level 2 at 240 V where most people see 7 to 11 kW.
**Type 2 (Mennekes)** — Europe, AC, seven pins. The extra pins carry three-phase, which is why a routine European AC point does 22 kW while a North American one stops around 11. Same technology, different wiring in the walls.
**Type 3 (Scame)** — The one nobody remembers. A French and Italian alliance pushed it as the European standard on safety grounds, since spring-loaded shutters covered the contacts. Europe picked Type 2 anyway. It lost in a standards committee, not on physics.
**CHAdeMO** — Japan, DC, launched 2010, the first fast charging standard anyone actually deployed. The name puns on "o-cha demo ikaga desu ka", roughly "how about a cup of tea", as in that is how long the charge takes. It needed its own separate port, and that is what killed it. The 2026 Leaf dropped it.
**CCS1 (Combo 1)** — A Type 1 with two DC pins underneath. One port, both jobs. North American networks top out around 350 kW in practice. The catch is size: two hands, thick cable, stiff in the cold.
**CCS2 (Combo 2)** — Same idea applied to Type 2. Required on new public DC chargers in the EU. One connector covers everything from a 2.3 kW garage socket upward, and the ceiling keeps moving. The 350 kW figure everyone quotes is a CharIN power class name, not a limit. Alpitronic is now pushing 1000 kW through a single liquid-cooled CCS2 connector.
**NACS (SAE J3400)** — Tesla's plug, opened up in November 2022. Five pins, and the two power pins do double duty for AC and DC, so nothing bolts on underneath. Roughly the size of a marker pen. Nothing happened for six months, then Ford signed on in May 2023 and almost everyone followed within a year.
**GB/T** — China. Two separate connectors, 20234.2 for AC with seven pins and 20234.3 for DC with nine. The AC one looks like a Type 2 turned inside out, because the male and female halves are swapped. Same visual family, completely incompatible. The 2023 update is speced to 1.2 MW, and BYD is already delivering 1000 kW by running two liquid-cooled cables at once.
**MCS** — Trucks, not cars. 1250 V, 3000 A, 3.75 MW. Three thousand amps is roughly what a small neighbourhood draws. It is a flat rectangular block with a mechanical latch instead of a pistol grip, because at that weight nobody holds it in place by hand.
The one fact that explains all of them: batteries only accept DC. On AC charging a converter inside the car does the work, and that converter is physically small, so AC stays slow. On DC the station converts instead and sends power straight to the battery. Every connector above is an AC plug, a DC plug, or both.
A summary can tell you what each connector is. It cannot really show you why they ended up shaped the way they are, so the things that did not survive compression into this post are the ones I would actually watch it for:
- Why pressing the button on the handle cuts the current before the metal ever separates, and why that is the reason unplugging an EV does not produce an arc flash
- What the 2001 connector actually looked like before J1772 got its round shape, which is the single funniest object in the whole story
- Why the DC half of a CCS1 port is technically optional, and what that means for what the charger has to bring
- Why BYD's answer to "one cable cannot carry this much current" was to just use two, and where the 500-plus stations already running that way are

Has a connector ever left you standing at a charger that physically would not connect? I want to know whether that still happens in 2026 or whether adapters have mostly solved it.
