It's also just great that the USA has decided to cede this entire market to China.
Still this is why I said short to medium haul not long haul. But that’s more than half of aviation.
Quick napkin math:
- The Hyundai Ioniq 6 gets 4.2mi/kWh (6.76km/kWh) [0]
- 3000km/6.76 = 443kWh
- 443 kWh in 5 mins = throughput of 2200 kWh, times however many charging stations at a refill stop. As EVs get more prevalent every charger at a station could be in use at the same time.

There are two main ways of handling that randomness.
1. Spread it over a large number of vehicles, and let statistics average out the demand spikes. We're doing this at a significant rate, adding > 1 million EV's to American roads every year. Also, we already have superchargers with 98 stalls. There's going to be little demand difference between 98 350kW chargers vs 32 1MW chargers. 9 350kW vs 3 1MW chargers loads a grid harder, but 98 vs 32 not so much.
2. Batteries. Charging stations are already large enough that many are utilizing batteries to smooth electricity demands.
the physical dimension you're looking for is power (kW)
443 kWh / 5 minutes = 443 kWh * (1/12 h) = 5316kW
I also don't think people will mind waiting a bit longer if it means even getting 1000km or many hundreds of miles.
Tesla’s monstrous EV truck charger puts out 1.2MW, and it’s already wild, as well as an infrastructure problem more than anything else.
I’m betting on battery swapping as the future, we already have it in 3 minutes, next-gen stations are dropping to 90 seconds for a swap. No charger will ever compete with that unless we discover entirely new power transmission tech.
The swap stations can trickle charge, don’t need massive power lines, and can also balance the grid. Batteries are less stressed, can be monitored and (re)cycled safely at scale. Fast cycle times means more capacity = less queues. Once the technology involved is standardized [1] and becomes a commodity there will be almost no downsides.

Seems silly for passenger car usage though where you could just use a much smaller battery using the same tech to get plenty of rang and so cut weight and get better efficiency.
BMW made a big bet that batteries would remain expensive and weight would matter for EVs. i3 and i8 were studies in scaling up structural carbon fibre mass production based on that bet that failed pretty badly.
Structural batteries are already a thing. Carbon fibre won't be the housing without a bunch of innovations.
Indeed the best use of this tech would be a smaller capacity battery with ±1000km range, though achieving <10m charging time even on that will still be a challenge.
IIUC, the big problem is that people didn't want to end up with a worse battery than their current one.
But if it did need to handle that level of instantaneous load, it would be straight forward to supply. 98 Tesla's worth of batteries on site could do it. The grid tie is substantially smaller, because the grid tie only has to handle average load, not instantaneous load.
There is already a similar tech for buses in Geneva, Switzerland:

America is the undisputed King of software. That is subject to change, especially with your tech leaders pushing hard to create a technocracy. You have successfully spooked your greatest ally, Europe into building for themselves and they already have a lot in place. Good for them.
The US is even losing software ground with your own people who trust your less and less (scandal after scandal will do that)
What you are left with is selling your software to the Third World, but that is not very lucrative, obviously.
As far as chips are concerned ,I pessimistically give it 5 years for China to equal you in that space. They will not be buying from you anymore, and they have football fields of the smartest people now, in all major field. And they are united in the fact that you don't want to share your toys, so they will use their number one manufacturing and research capacity to upend you.
It's not a fight we're up for and not one we can win anyway. It's not because of arrogance, stupidity or laziness. Every empire collapses eventually. China will too one day.

The US doesn't make chips.
It sounds like this is more motivated by a need for vengeance than a desire to delineate the truth.
