Cars, it's electric! Do Do Do

Toyota coming out with a solid-state battery that goes 745 miles and charges in 10 minutes. Even they are saying adios to H2:

"While Toyota has been a proponent of hydrogen cars, this breakthrough in EV batteries suggests a shift in the company's approach to the post-ICE future."

Headlines about Toyota solid state batteries

2023: "Toyota to roll out solid-state-battery EVs as soon as 2027"

2020: "Toyota's Quick-Charging Solid-State Battery Coming in 2025"

2017: "Toyota’s new solid-state battery could make its way to cars by 2020"

2014: "Toyota to Offer High Performance Solid-State Batteries in 2020

Would be nice if its true, but they have been saying this for almost 10 years now.

Just a matter of time. All the big auto companies are working on it. It's not like ss batteries don't exist now.

745 miles of charge in 10 minutes doesn't even make sense. You can't physically make a connector on the car that can handle that kind of power without melting. 1500amps @ 800V for 10 minutes?

Even if that was 20% to 80% type of charging in 10 minutes it's still probably around 1200A at a 800V. They going to higher those Strongest Man winners to man the station to lift the connector and cable onto the car?

If they're going to make shit up, why not just say it'll just need one charge a year and it can go 15,000 miles?

I tried to find the actual quote regarding 10 minutes, but the original Guardian article just states the same thing. My best guess is that it's something like the battery composition would allow it, but as you point out I'm not sure how it could possibly be done in practice.

Maybe they will use an inductive charging pad ?? 😀

Too bad the term lightning connector is already taken.

As an aside - I think a robot arm to handle the attachment is the wtg. can include a drying agent if raining/wet,
takes any concerns of weight away - even dealing with the cable is a problem for some.

10 simultaneous connections.

See Borg Queen for example

Isn't there a Toyota charging station not far from you?

I'm a chemist and not an EE but everyone seems to be saying the same thing - more energy density and faster charging:

"We're increasing the battery's energy density by up to 50% or more, and enabling battery manufacturers to bring charging times way down to the point where recharging your car gets closer to refilling your tank," says Grant Ray of Group14."

First article you posted actually has good info, but the amount of effort required to do a 10 minute charge is huge. Lots of crazy $$$ technology with minimal payback.

Which hardly matters if you just extend the time to a reasonable "fast" recharge time combined with charging overnight. If you've got a long road trip and we get more stations where there's food stops people will be covered.

And longer waits of a half hour plus during long road trips is offset by leaving your house with a full charge on a regular basis.
 
The gauge of copper to carry current for some of these claims, would be big. As Santapez pointed out, you would need a body builder to lift the charge cables, and it would not be flexible.

I think faster charging time isn't the key benefit of SS batteries, it's increased range. Once you get the range to 700 -800 miles, that's where most would call it a day on a long road trip anyway. Then you have all night to recharge.
 
Rental of battery trailers for long trips. Maybe they have minimal storage for "stuff" but mostly towing extra juice......
