This problem could also be solved by using battery swap stations, where batteries charge much slower but the change is nearly instant. It's already a standard for electric motorbikes in Asia, especially for delivery folks.

I tried a system like this about 15 years ago, and it was unweildy: https://en.wikipedia.org/wiki/Better_Place_(company) https://en.wikipedia.org/wiki/Better_Place_(company)

  China is propelling its electric truck market by embracing battery swapping. In 2022, China sold 36,000 electric trucks, 91% of the global total..support for battery swapping is playing a key role. With plug-in charging, it usually takes 40 minutes with DC fast charging or several hours via regular charging to recharge an electric truck. In contrast, battery swapping only takes 3–6 minutes. https://theicct.org/china-is-propelling-its-electric-truck-market-aug23/ https://theicct.org/china-is-propelling-its-electric-truck-m...

The NIO car company sells cars with swappable batteries and has built battery swap stations in Netherlands, Germany, Denmark, Norway and Sweden. The swap action looks slow and very particular still to be honest, but there's probably good reasons behind it (including not wanting actuators on the car itself): https://www.youtube.com/watch?v=aBdQQxgxDrY https://www.youtube.com/watch?v=aBdQQxgxDrY

  The swap takes six minutes (example https://www.youtube.com/watch?v=VmWL1hZQmD0 https://www.youtube.com/watch?v=VmWL1hZQmD0). The swap stations charge the packs to 90%. So swapping in a 100 kWh pack that has been charged to 90 kWh is the equivalent of charging the car at 900 kW. Nio will start introducing 150 kWh packs in the same physical form factor which they charge to 135 kWh. Swapping one of those in would be the equivalent of charging at 1.35 megawatts.
