Quick change - with 3 guys a tow truck and a small manual crane. Sheesh.
For when 41kWh just isn't enough...

Looks like fun though - the driving that is - not the changing.

Now if they only had a 50kVA genny to recharge the spare while bustin those dunes!

Sort of defeats the purpose doesn't it? A better option would be solar charged spare packs.

The old quickswap battery seems to always be in the domain of heavy lift cranes etc and will never work commercially without Tesla size commitment. (Better place anyone?)

What if someone made cells the same size and shape as cans of soda, then belt-fed them along nylon channels.
A clamp could then engage each cell in groups of however many to make up the pack voltage.

When you want to quick swap out the battery, you just unclamp and drag out the belt load of cells, while dragging in a new fresh set.

Or hell, if the cells were tough enough, you could just open a hatch and that'd all tumble out like a drink machine gone wild.

Certainly the logistics of distributing cans by the millions is already in place, the system of loading and pulling large heavy belts along slippery nylon channel/runners is about as simple as Lego, and the manufacturers of EVs only have to worry about placement of standard size nylon channels and the clamp system that connects it all up, while locking it in place.

Talk about future-proof batteries.

While you're at it, each can-cell could have a convenient USB port with simple 3.7-5v converter so you can just grab a can for portable USB charging power from the very same power source as your car!!

Too easy... now....who's got the cash to make that reality?
