"Toyota Claims Breakthrough That Will Lead To 745-Mile EV Battery
The Japanese automaker says it will soon be able to manufacture a solid-state pack that can charge in 10 minutes."

"lighter, less complicated cars" huh?

You know what would make cars lighter? Not insisting they all be lifted minivans that do a thousand miles on a charge!!

[Specter]

They have newer tech out that is supercap based.  The systems I think can go to 400 volts or so if I am not mistaken, can charge at hundreds of amps, and of course discharge at same rate.  With some clever relay switching you could potentially say break your bank into 2 or 3 packs, run in series for high voltage, charge the 3 banks in parallel to keep voltages down but really pump the amps to them to get the fast charge w/o violating that 200 or whatever amp charge rate.  Of course there would be the balancing but that's always an issue no matter what the tech, BUT being cap tech, and essentially an electrostatic charge based and not chemical base, the balance ideally should only take a few minutes tops.

As usual I don't think I will hold my breath until the new EV battery vaporware arrives.

they make other products too, but here is a power supply / battery. well it's really a capacitor storage system that holds kilowatt hours of energy.

a bit on the heavy side for now but they are constantly improving things and it has a life cycle of like a million cycles and can charge very fast / discharge very fast.

They might be looking at something like this or a hybrid of something like this.

That's exciting news! Toyota's breakthrough in solid-state battery technology is a significant development for the electric vehicle (EV) industry. The ability to manufacture a solid-state battery pack that can charge in just 10 minutes is a game-changer. Solid-state batteries offer several advantages over traditional lithium-ion batteries, including increased energy density, improved safety, and faster charging capabilities. With a claimed range of 745 miles, this breakthrough has the potential to address one of the main concerns surrounding EVs – range anxiety. If Toyota successfully brought this technology to market, it could revolutionize the EV landscape and accelerate the adoption of electric vehicles on a global scale. A solid-state battery that can charge quickly and provide an extended range would greatly enhance the convenience and appeal of EVs for consumers. We eagerly await further developments from Toyota and other manufacturers in the field of solid-state batteries. This innovation holds tremendous promise for the future of sustainable transportation, offering the potential for longer trips and faster charging times, ultimately making EVs even more practical and accessible for everyone.

I think that the "10 minute charging" BS needs to stop. Don't care how capable the battery is, nobody's going to build megawatt power stations attached to every DC charging outpost. Or even some of them. I think the fastest chargers we have over here are 350kW and I think there are maybe only 50 in the entire country and if anyone else rocks up to use them at the same time as you you'll be getting 175kW.

At 350kW you could charge a typical EV-sized battery in 15 minutes. At the expense of drawing enough power to run an entire street.

I just think the EV battery vaporware needs to stop. It is rather endless. And IMO, the "problem" is exaggerated. I think most of us enjoy a short rest after a 200-mile drive or 100-mile ride.


I think a lot of the BS comes from those anti-Evers who say they can fill their gas tanks in two minutes--so we have people trying to fix the issue which IMO, is not much of an issue at all, but with one big exception.


The only realistic issue is those who cannot ever charge at home. Such as most people who live in places such as San Francisco (countless more cars than garages). Then superfast charging on the street could be important.

San Francisco's problem is cars, not lack of charging... the whole point of a city is so that everyone is close enough together to not have to travel, and yet, here we are...

I would say it's both. If every one of those cars were in a garage with home charging, there would be no problem at all with either. Not enough garages in SF for the number of cars and countless people have to park several blocks from home if they are lucky enough to find a parking space in a reasonable amount of time even then.


Most people even in SF find they need a car for many things. Many in SF work outside the city, for one thing.


I would NOT want an EV if I lived in such an area with no garage.

It looks like we might be close to the next jump in battery cell energy density.
The Toyota press release along with those from other companies says to me 500Wh/Kg cells are moving out of the labs and into production.
https://amprius.com/the-all-new-amprius-500-wh-kg-battery-platform-is-here/
https://newatlas.com/energy/catl-500-wh-kg-condensed-battery/

The cells currently used in EV's are around 300Wh/kg, an increase to 500Wh/kg would provide 40% more range.
A 40% increase in range for the same weight battery pack is nice but the flip side of that is more exciting to me; The same range with a 40% reduction in total cell weight.

[MVetter]

Also affords luxuries that take space/weight like potential liquid cooling.

[Stonewolf]

Honsetly the same range but with active thermal management for faster, more consistent charging is *way* more interesting to me than just a bigger battery pack with the same drawbacks.

[princec]

Can't wait for it in bikes, not really fussed about cars. I don't exactly have to pick up my Ioniq 5 when it falls over so I really don't care how heavy it is, and I charge it at 7kW at home overnight anyway.

@DonTom I think you missed the point I was making about SF. SF needs to ditch its car culture altogether. The whole city is choked beyond redemption by 20 million people who for some reason seem to need to haul themselves plus two tonnes of steel 100 miles every day to somewhere else. What the actual fuck. Everything is wrong.

[Specter]

California should ditch electric vehicles all together.
They can't even keep the lights and AC's on now due to their incompetence, ignorance and grid management malfeasance, what makes them even begin to think they will be able to keep those cars running when there is an additional gigawatt or 5 of demand on a system that is already broken?

cas you may get your wish.  All those cars will be off the streets real soon if there is no electric to charge them!  For those who have solar panels, I can see the commie bastards over there now telling you, you have to give the electric to the government to dole out, for the 'greater good'.  With everything being IoT,  the Interconnection of Tards I call it.  They'll just remotely disable your vehicle to keep you in compliance.  It's coming, mark my words.
