I wonder if the EV cannonball community will start to experiment with the battery packs. I know that some of the combustion engine runs have usually carried extra fuel tanks...could the same sort of idea be viable for the EV versions? (though I imagine the weight of the batteries would be too much to deal with).

If you don't care about battery damage, could probably increase the charge rate without a larger battery on board.

Sure might increase the ods of a battery catching fire, or reduction in battery life. But if you're trying to get the fastest time...you might not care

Might explain why this record is being set in early January when the temperatures are cooler = faster charges but not too cold.

You could always develop a small trailer-based solution that is aerodynamic and towed behind the car. Have them placed ahead of time on the route, and drive to each to swap out. Should be a relatively quick changeover (<60 seconds with practice).

You’ll need faster charging and larger batteries (larger batteries allow for sustained peak charge rates longer when you roll into a charger station at very low state of charge).

Taycan has an 800V battery pack, so can leverage higher Fast DC charge peaks from CCS chargers (vs Tesla 400V packs and Superchargers).

All the competitive (ICE) runs have additional fuel cells.

Usually just large bladder in the trunk.
