Theory is easy; the awkward moments at 11 pm at a motorway hub are where etiquette either works or it doesn't. Here's how to handle the situations that actually come up.
All stalls full when you arrive: park in a non-charging bay (or just outside the marked area without blocking traffic), walk over to the plugged-in cars, and politely ask roughly how long each driver has. Most will give you a real number — 5, 10, 25 minutes. Form a mental queue. Some networks (Tesla, Ionity) now show live SoC and estimated session end in the app; use it before you ask in person.
Idle fee handling: networks like Tesla Supercharger, Ionity and Evie charge a per-minute idle fee once the session ends and you're still plugged in, often around £0.50–£1.00 per minute during busy hours. Set a phone alarm 2 minutes before the expected finish time, and move the car promptly when it does. Most apps will also push a notification when the session ends — enable it.
Blocked by an ICE car: don't get into a confrontation. Photograph the bay (including the EV-only signage), report it via the operator app's 'report an issue' flow, and if there's a site contact (petrol station cashier, hotel reception, shopping-centre security) tell them politely — they usually have a process. In the UK and many EU/AU cities, ICEing a charging bay carries a fine and operators do enforce it, but only when they have a report.
Charger is broken when you arrive: try the next stall on the same site first — most outages are stall-specific, not site-wide. If everything is dead, report it (operator app, EV Charge Routes 'report an issue' button on the station page) and reroute to your backup site. This is why every long-trip stop should have a Plan B within 10–15 minutes; see our road-trip planning guide.
Cable won't unlock at the end of your session: don't panic. Stop the session in the app first, wait 10 seconds, then try the car's release button. If the cable still won't release, lock and unlock the car. If still stuck, call the operator's helpline — every cabinet has the number. Never try to force the connector out.
