I've seen CHAdeMO stations that display the car's SOC on the screen, but can some J1772s do this? Otherwise how would the person have known your Tesla was fully charged?
And they knew the car was full how?
Yes it displays on the screen and the charge port lights up, BUT ONLY IF YOU HAVE THE KEY FOB PRESENT. A stranger would see neither.Not 100% on this as I'm still waiting for mine to arrive, but I believe the rep told me its displayed on the big screen which should be easy to see?
Maybe it's the charger changes colour like the other poster mentioned (not sure if this happens)
