Tim,

I charge mostly at home, I have a SyncEV connection point, £490.00 fitted after the Government grant. It charges at 7kwh, so in bright sunlight it is 50% free, using power from the PV panels.
Away from home I used the free Pod Point chargers at Tesco, mostly because the parking bays are wider than the standard ones and they are near the front entrance.
I've used the Amesbury Supercharger once as I have 1000 free miles to use. It charges at 250 amps and it was quite amazing to see range being added at 300 miles in 1 hour.

As Neil has said, the superchargers are smart and payment is collected from the card registered to your Tesla account because the Supercharger knows who owns the car that has been connected. So for other EV owners to use the Superchargers they would have to set up a Tesla account. Simple and easy to do for Tesla, one price for Tesla owners, another for third party cars. But is that something that people like Mercedes, BMW, VAG etc would want?
