The first time I plugged into a 7kw public charging point at a large shopping centre last year, I could not get the post to deliver a charge.
I had a suitable RFID card, but could not get it to work.
Then a kind local guy rolls up with his family and jumps out and has his car charging in about 30 seconds !.
He could see me scratching my head and came over.
He told me to unplug from the car.
Then with the type 2 lead plugged into the post only, offer up the RFID to the viewer on the post.
Then when I get the green “Okay” tick on the screen, plug into the car.
Worked like a dream !.
I felt like a complete “Nubby” - which I was.
The protocol differs for some units, but by and large, this appears to be the most common way of getting a charge.
Cable into the post first, then RFID card ( if required ) then plug into the car.
At the Pod Point posts, they are just “Plug And Play” in a lot of cases.
But don’t forget to use the Pod Point App on your phone, or the charge will STOP

after about 15 mins.
Tesco use a lot of these units.
They are free to use, while shopping.
