All of that goes out of the window if you read what I have been saying this entire time: this would be absolutely unaffordable to you and me, in battery costs but also charger and infrastructure costs. It would take a national infrastructure upgrade to accommodate that precious 9 minute charging figure. Forget a 200A panel for home charging (not that expensive compared to what you just listed), I'm sure this would require more and take 5x as long at home.

You are advocating for an unproven and expensive technology for ever-changing reasons, all while we just got our current tech in a decent place. What you are asking for would ultimately make it more difficult to own an EV and likely harm EV adoption. We aren't there yet, and it's really not necessary now.

So, if you don't own an EV, why do you continue to talk like you know what is best for consumer adoption? Why not listen to the consumers that actually have them instead of insisting you need to drive 450+ miles in one sitting without ever stopping?

That's the trick though, the current tech is NOT in a decent place. When it takes <10 minutes to fill a gasoline car at a pump, but it takes 40 to 60 minutes (or more!) to charge an EV, this new tech is absolutely a necessity.

I talk about consumer adoption because I research this stuff. EV sales are down, they're down because of the problems I've already noted with range, charging time, and charging availability. Increasing the range increases the time between charges. Decreasing the charge time makes it more convenient to re-charge.

""It might make sense [to buy an EV] if you could recharge that vehicle in the driveway of your house while you're asleep," he says. "The problem is that many Americans don't even have driveways." J.D. Power's Krear adds that "one in three shoppers don't have access to home charging". 

At this point, even figuring in the drive to a fossil-fuel station, "it's still much easier to refuel your vehicle with gasoline than with electrons", says Nunes. "If you pull up to a gas station with an empty tank, and you just pump it full of gas, it'll take you maybe six, seven minutes at the most. With EVs, it's going to take you hours to charge that vehicle to the maximum rate. And that's the kind of time that everyday Americans simply don't have."

Experts agree that establishing a robust infrastructure of public charging stations is key to mass adoption of EVs. But the creation of that infrastructure lags. Stations are scarce, particularly in low-income and minority communities. Where they do exist, they are often unreliable.

With EVs, it's going to take you hours to charge that vehicle to the maximum rate. And that's the kind of time that everyday Americans simply don't have – Ashley Nunes

"One out of every five public charging attempts is a failure," says Krear. Findings from a 2022 University of California, Berkely study showed that one-quarter of public chargers in the San Francisco Bay Area didn't work due to "unresponsive or unavailable screens, payment system failures, charge initiation failures, network failures, or broken connectors"."

It does not take 40 minutes in modern EVs. It takes like 20 minutes, max. It certainly does not take hours at L3 chargers like the misleading claim the person in your quote makes. I think that's also what you're missing: this is a marginal improvement overall, other than range itself. Once again, the problem is not battery tech, it's charging access. L3 charging access needs to be improved, not battery tech. If we upgrade our battery tech now, it will only make the problems you are mentioning worse by reducing the amount of available chargers. This will not work with our current L3/L2 tech, and you want to make the L3 charging situation you're talking about even worse. We simply do not have our infrastructure in a good enough place where we can accommodate this technology.

Research and quote things all you want, it doesn't change the fact that you have never personally owned one and therefore should not be speaking on this subject like you are an authority. This isn't the first time we've had this "chat" and I'm sure I'll see you claiming you need to drive 450+ miles in a single sitting the next time this gets posted and we can go in circles again.

For now, I see that you think your needs and wants are what everyone else's are (this is not the case), and that because you think you know best (again, without ever owning an EV) you will never admit that maybe your need to drive 450+ miles is unnecessary with today's EVs and that it would cost unfathomable amounts to upgrade cars and infrastructure to even use this tech. See you in the next post, I can't wait for you to tell me more about how I can't road trip in my EV even though I've done it across the country!
