What is a Charge Port / Charging Socket?
The socket on the car — usually Type 2 for AC and CCS for DC rapid charging.

In plain English
The charge port is the physical socket on the outside of the car where you plug a cable in. In the UK and Europe, almost all EVs use a Type 2 socket for AC (home and destination) charging, and a CCS2 socket — Type 2 with two extra DC pins underneath — for rapid DC charging. Older Nissan Leafs use CHAdeMO instead, and Teslas use a slightly different connector but are now opening up to CCS.
"It's the petrol filler cap of an EV — but smarter. It talks to the pump before fuel flows, and locks the nozzle in so nobody can yank it out while you're inside the shop."
How it works
Inside the port are signal pins that "handshake" with the charger before any high-voltage power flows — they confirm the cable is locked, agree on a charging speed, and check there are no faults. Only then do the heavy power pins go live. A small motor or latch locks the cable in place while charging so it can't be pulled out.
Signs of trouble
- ⚠Cable won't lock or release
- ⚠"Charging fault" or "Check charge port" warning
- ⚠Burn marks or melted plastic around the pins
