I’m just playing messenger forwarding this from a sympathizer and well wishing owner of a small EV wagon.

To charge the R1T's 135kWh battery in 10 minutes would require an average power of 900kW over 10 minutes. That is 2000 amps at 450 volts. The truck's CCS connector, internal wiring, contactors and BMS would have to be completely redesigned to endure the 2000 amps. Plus the 2170 cells in the R1T cannot be charged in 10 minutes without severely reducing their lifetime and without causing significant overheating.

Of course - our moms and dads told us that if it seemed too gos to be true…….
Time to chime in and since some of this was supposedly funded by your fed, tell your lawmakers to stop the insanity - much wise than those $500 toilet seats and $400 hammers from not too long ago

The problem here is not the research or the dollars that flow into it, which is necessary for science to progress so that eventually we will get to ultra-fast charging. The problem is the overinterpretation that many science journalists engage in. Don't blame the feds for spending money on research, we would be in the dark ages if that didn't happen. And btw it's quite different from overexpenditures in procurement, which can be a problem but are usually overblown as well.

That article is very misleading because it talks about a device that supposedly can charge standard batteries in 10 minutes. What the researches have done is develop a battery cell that can be recharged in 10 minutes by incorporating a way to quickly control its temperature. Here is a different article that gets things right.

Here is a scientific paper that explains in detail how the new battery cell works.
