I’m sorry but that’s patently untrue. Why is 400 miles the thing to aim for? When it was 300 miles three years ago apparently. Also I notice you’re now talking about bad weather and real world conditions. See how it works? You’ve ALREADY changed the goalposts now I’ve pointed out that 400 mile EV exist. It’s how it works. I’ve had enough anti EV conversations to know how this game plays out. You’ll ALWAYS invent scenarios that the EV can’t make. Until it can. Then you’ll adjust the parameters.
So I’ll ask again, why is 400 miles the aim?
No I haven't changed the goalposts.
Here is the calc. From Edinburgh I want to travel to Hertfordshire, distance is 392 miles, maybe 378 if I use the A697 instead of A1.
The range on my car when I set off was 290, the car was fully charged. As I went south, the range dropped to 278. I stopped at Woolley Edge to recharge after 236 miles. I recharged to 208 miles, which took 45 minutes after a short wait for the charger.
So I set off again with 172 miles to go. I drove into heavy rain, and then roadworks near Luton. The range had dropped from 208 miles to 197. By the time I arrived there was 25 miles left in the battery. With no charger at my destination I had to get up early to charge the car the next day - couldn't do it that evening. So that was about an hour to get it back to 80%.
Then on the way home I had to stop twice to recharge. 90 minutes, and the cost per mile was greater than diesel. There are no services north of Newcastle on the A1 or A697, just petrol station stations with chargers. Stopping there is ok but you can't really do anything but sit in the car.
So that's why I want a 400 mile EV. I'd be able to get there without charging, and then charge when it's convenient, and then go home again without charging.
Your calcs are English centric. Even in Britain people travel further than 250 miles. In the US or Canada or Germany or almost anywhere 400 miles is as much as you'd want to drive in a day, but people do it and don't want to be delayed by 40 minutes or more at a charger.
So, no I'm not moving goalposts. But given that charging at public chargers costs at least the same as ICE, and takes 10 times longer, stopping twice is just not going to cut it.
