There is a huge missed opportunity of having modular battery packs that you can load into EVs.

You don’t need a huge battery for everyday, in fact it makes your drive less efficient.

What if there were standards and you could go to a gas station and rent some packs. Put them in the trunk (there would be slots and/or standard connectors), and then drive off.

Once road trip is over you return the packs (or you could buy instead of rent).

You can also just swap the packs in gas stations with fully charged equivalent, making long trips more flexible.

I think china did something like that with scooters.
