The whole repair thing should made super easy if we want EVs to succeed.

  1. Make all batteries use an easily swappable set of standard cell sizes.
  2. Make battery controllers standardised and swappable.
  3. …. Er… that’s it.

Make all cars rechargeable with a single charging port. And that port should be USB-C

like 50 USB-C cables tied together to output enough of a charge lol

I've been surprised by USB-C. I recently bought a Xiaomi phone and it takes like 10 minutes to charge with the charger that comes with the phone (and it still works with the other ones). It's 120 watts

At that rate it'd still take 12 hours to charge a 1440 watt hour battery, which isn't the hour or two that people are used to with superchargers these days, but actually surprisingly servicable.

I don't think there is a car with only 1.44kWh. USB power delivery can do 240W max, so you would already need 11 to max out a normal European power socket. To match a modern 350 kW EV charger, you would need at least 1458 USB cables.
