I filled up today, well put 30 litres in.
The car in front of me was already filling up, was ten minutes before they came back to the car (with coffees), then 4 minutes before they pulled away.
I filled up in 3 minutes (pay at pump).
So a total of 17 minutes.
Now a 150 kW charger could probably pump in 40 kWh in that time, so about 160 miles.
I looked at this a few years back, worked out that we could charge 3.5 million cars without any changes (apart from charging points), and 7.5 million cars with minor changes, but all without adding capacity or infrastructure.
I posted it up here somewhere.
