1000km is 620 miles. That's heading for a 10 hour journey without stopping. No way am I prepared to do that. I don't have your stamina or concentration span.

For me, personally, without other considerations, my ideal EV would cover me to probably stop every three hours for a break. That's around 270 miles if I'm on a motorway 100% of the route, so I'd be happiest with an EV with a stated range of 400 miles to have 50% more than I need, and would want to charge from 50 left up to 320 left in ideally 20 minutes to half an hour. (Once the family has all been to the loo and I've looked at the route ahead and caught up with my messages, 20 minutes has flown by.) 400 miles stated range is roughly 100kwh capacity, charging 270 miles in 20 mins is 67.5 kwh in 1/3 hr, so 202.5kw charger.

Motorway service stations are installing 350kw chargers although a bunch of them still have 100kw or 150kw max, and some just 50kw.

I reckon my absolutely ideal EV will be on the market in a few years with plenty of fast enough chargers and I'll buy it second hand a few years after that, by which time I'll have had this EV, my most fun to drive vehicle ever, for a decade and my wife will be happy to swap it out.
