The thing is, with the range of a petrol / diesel car you wouldn’t need to be re-fueling at a motorway service station. When I had my EV it was costing my company around £24 to fully charge it on the motorway and I was getting a max of 180 miles for that sometimes 130 miles. Prices have increased massively since then.
August 21 we did a 400 mile round trip plus whatever mileage we put on around our destination. This was done charging at Exeter (there and back), Wincanton Morrisons (both ways) and Lidl on the way back. The total cost for all those miles was less than £20. Late last year I had to put a boost charge into the car at the local McDonalds, it was about 20 minutes worth and cost £21 for just over 100 miles extra. If that was my only options for charging, I’d be driving a petrol right now, for sure.
