Impressive if it works, but I wonder if there's an electricity grid that could support it?
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.
I remember investing in solid state battery stocks and ended up losing a lot of money, good to see that the premise behind them is solid - if this pans out, this will be revolutionary indeed.
I also don't think people will mind waiting a bit longer if it means even getting 1000km or many hundreds of miles.
Not really feasible for cars. You’d need a 4.8MW charger, 6000 amps at 800V, to charge this battery in five minutes – maybe more, this a conservative estimate ignoring losses and assuming 400kWh capacity.
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.

It's also just great that the USA has decided to cede this entire market to China.
