Unrelated, but does anyone know how many electric cars have an autonomy of more than 700km, while also charging fully in less than one hour? Is that even possible with the current technology?

Get a motorcycle in the class of Honda Goldwing, convert it to electric power, and replace all of the luxury fuffle on it with batteries. I don't think this will match your expectations, but this is the best take on what you want I can think of

  Electric motorcycles aren’t a thing I knew I needed yet (despite scooters existing)... I imagine they’d be quite fun

    I'm pointing to the use of motorcycle because of battery mass ratio. At some point, you can not improving the range any more by adding more batteries because any gain will be eaten by more rolling resistance. At some point you will arrive to the point when your vehicle starts to resemble a battery stack with two wheels.

Currently - none that I know of. Tesla is currently approaching that number with 592km(370 miles) of range. As for charging _fully_ - that's rarely done in practice, because over 80% li-ion batteries charge much slower. Bjørn Nyland recently beat the record[0] for longest distance travelled in an EV in 24h (2781km) by stopping to charge from 10% to 50%, because only then he could use the full power of superchargers.

Most of the more expensive EVs come pretty close to that and seem to be competing on getting the numbers better there. E.g. I think Tesla is planning to break the 400 mile barrier pretty soon. 300 mile is pretty normal already. Most EVs charge pretty quickly to about 80%. 20 minutes to half an hour gets you plenty of range. Mostly EV owners don't charge to 100% unless they are at home or doing some overnight stop. I think most normal drivers on a cross country trip need bathroom breaks, lunch/snacks/drinks, leg stretching etc. every 2-3 hours. Great opportunity to plug in and recharge enough for another 2-3 hours. Range anxiety is mostly irrational and mostly a non technical problem as your car probably has more endurance than you.

  Have EV companies completely abandoned the swappable battery idea? I always thought thatd be the endgame. Some standardized battery design where you roll up on top of a station and it swaps the battery underneath the car. Or maybe this is something your car does for you before arriving. Which eliminates the amount of dead time tens of thousands cars will need to spend while using up expensive property in cities while charging.

    I don't think that ever was a serious plan.
