I’m not confused here, to be clear. There is a giant transformer that converts from mid voltage AC to low voltage AC at most installations. Because they draw so much power they need their own dedicated transformers. There’s sometimes (depending on the installation) a separate cabinet to convert the AC to DC and then transfers it to dispensers, though, as you say. The more modern high power ones tend to use separate cabinets, I’d agree. Older ones could take 3-phase AC directly since they’re much lower power overall. |

What is commonly talked about here are DC fast chargers, where the actual "charger" is an AC to DC cabinet on-site. Those chargers could be connected to one or many dispensers. The dispensers are the things with the cables that plug into the car, handle payment negotiation, and relay battery state to the charger in the cabinet. You could have multiple dispensers to chargers in this setup.
The technical English parlance here would be EVSE for the Level 2 chargers (the smart relay things), and dispensers for the pedestals with the cables for DC fast chargers (DCFCs).
