Toyota Touts 745-mile range, 10 minute charge for Solid-State battery

Fusion is also right around the corner!

I think we’re looking at EVs for personal transport but hydrogen will play a role in heavy industry, aviation, and maybe long haul trucking

Hydrogen in the aviation sector has a great record!

Solid State batteries are the future. Not to start a war in this thread, but the battery tech is so much more important than the stupid ? 'ing port.

Batteries of today use liquid electrolyte which creates a risk for explosion or fire. Solid State batteries have zero liquid electrolyte so they have almost zero risk of fire. They are also much more energy dense, and can be charged at much faster rates.

The entire charging infrastructure and battery technology landscape will look completely different 5 years from now.

Companies that are publically traded have been working on Solid State batteries for years. One of the biggest players, Solid Power, is licensing its technology to BMW and you can expect to see those EVs in the next 5 years.

Solid Power is one. Quantumscape is another. VW partnered with them for development. They have shipped products to vehicle manufacturers, and are happy with the testing so far. Their stock jumped 15% on the Toyota news, and stayed up on 2x volume today. Solid state is getting closer to reality, but I hear the "always a few years away" people loud and clear.

I agree at some point solid state will be viable for consumers just not sure this decade. They have been saying for at least 10 years now they will be available in 5 years.

They have some already, the issues they are struggling with are being able to manufacture at scale and that they need to be warmed up before each use. The ones they are currently using are in commercial vehicles like busses where they need to warm up for 30 minutes before they can drive but since they are used all day it is not as impactful.

Have not heard recently any updates around these 2 major obstacles so seems like progress is very slow.

Those obstacles are old news. The issue is scaling and cost at this point. Not trivial issues by any stretch.

Not to nitpick but 1 of the 2 issues I referenced was scaling. ??. ?

Oops - I deserved that.

Didn’t they announce in 2017 that they had production ready solid state batteries and all their cars even hybrids would have them by 2022?
A month ago their “head scientist“ said there are no battery breakthroughs on the the horizon, maybe in 10-20 years.

Yeah, and GM Mary in 2020 said GM would have 20 new EV's for sale in 2023 as well..

Hydrogen? That is absolutely never going to happen.

You don't need to tell me. Tell Toyota and basically ALL Japanese OEMs. Out of them, Honda is perhaps the most progressive in their approach to BEVs. But, it's mostly to claw back marketshare they lost to Toyota and others since their glory days of the 80s and 90s.

Honestly, the next big thing in batteries is probably Silicon Cathode. Silicon is much more common than Lithium.

I read a couple of the articles, Toyota said they would have new chemistry in 2025 but solid state is not expected until 2027-2028, which I still think is not likely.

For the charging speed, I’m sure it will increase between now and 2028 but if solid state has a flat curve, even today’s 350 kWh stations could charge 58 kW in 10 minutes. Based on the most efficient vehicles today at 4.1 miles per kW that would be an impressive 238 miles charged in 10 minutes. If they actually were able to squeeze that extra 20% range out of it that could be 285 miles in 10 minutes.

Here is a quote from the release regarding solid state:

”Toyota has also discovered a technological breakthrough with solid-state EV battery tech. The battery is expected to offer a 20% improvement in cruising range.

The automaker says it’s accelerating development and aims for mass production from 2027 to 2028, targeting 20% more range and a 10-minute quick charge. A higher-performance version is under research and development, which Toyota says will deliver 50% more cruising range, suggesting it would be over 900 miles.”

I hope the EV Tacoma rolls out with new battery tech, but I suspect they are still a long way off.

I just don't see the 10 min charging time.

They'd need something like a 1+MW charger.

There have been demo cables that can do this, but it isn't NACS or CCS it is something completely different.

So I do believe hydrogen has a chance

but only if we are able to perfect the fuel cell. So it will still be an EV but fueled by a hydrogen powered fuel cell

But today running an ice vehicle with a 10,000 psi hydrogen fuel tank probably will never make it. As said previously infrastructure is very costly and handling a high pressure hydrogen fuel hose fitting is a challenge.

That does even even address the fact that producing hydrogen today is 3-4 times more expensive as producing a similar amount of gasoline. It currently takes electricity to creat hydrogen but that is with todays technology which could change overnight

Has nothing to do with the equipment capabilities. You can't drop a multi megawatt load in the middle of nowhere without the grid infrastructure to back it up.

1 MW is equivalent to 400-900 homes.

I'm also not sure how the grid would react to such loads randomly appearing and disappearing. The electric grid is a giant balancing act with little room for error.

Tesla I'm sure will work around this with on site battery storage, where the grid demand will be smaller but more constant. That works fine until chargers are saturated and have to charge constantly for long periods of time ( weekends/holidays).

This reminds me of the "state of the art" 1" thin TV I bought a few years ago for about $3,500. Every year the price kept going down and the tech kept getting better. I can find better TVs for $800 now. I hope the same thing happens with EVs. What we buy today for close to $100k might be selling for $30k in a few years. It would make as much sense as the stock price. Lol!

There goes Toyota making crazy predictions they can't possibly make reality just before their earnings report showing how badly they're losing marketshare. My guess is Toyota is the next Kodak. They said all the same stuff 10+ years ago and look where they are now.
PS: The Toyota Mirai is the ugliest car I've ever seen. ?
