Batteries to an EV are what the engine is to a traditional ICE vehicle. They determine the performance capabilities of the power train (power, discharge rates, temperature limits, recharge rates, etc.).
The only way to significantly differentiate your powertrain from your competitors is via battery pack design. It is also the single most expensive component of the vehicle.
There is zero incentive to standardize on pack design. Hot swapping will never be a thing. I'm not giving my $30k battery pack to you for one of unknown history and capacity. If you are a fleet owner, sure, but not for the general public.
Swap this technological dead-end out for better batteries, improved superchargers and more universal EV charging standards
