Reply to comment by slyder777 in Toyota to Convert Older Cars to Eco-Friendly Models to Curb Emissions by renome

Tbf Toyota's supposed EV hesitancy isn't because they want to cling onto ICE cars, it's because they've sunk billions into Hydrogen cars and now they're in an awkward position where they're struggling to admit that they bet on the wrong horse.

They have been investing billions a year into solid state batteries. They can afford it.

Current battery tech isn't that great and we will run into problems if we keep going with it.

Betting on two horses is the smart thing. Besides that, hydrogen might be the better option for heavy trucks.

Oh yea they can definitely afford it, but what they need is time to catch up, which is why they're lobbying to slow down the EV rollout. They didn't really bet on two horses, they went all in on hydrogen. It's why they only have 1 electric car across their entire lineup right now.

They have registered the most Solid State Battery patents i believe. And actually have a working model.

I think they arent going all in on battery yet cause they dont believe the current battery tech is good enough long term. Which i agree with.

Which current battery tech will we run into problems with, and which problems?

ELB2001 t1_j4vvvua wrote

The amount of rare earth minerals needed for the current batteries and where they come from. The current Solid State batteries that are being worked on will need much less of those. This plays a big part in the high cost of the current tech.

the high weight it adds to the vehicle will also become a problem for the roads.

A high speed loading infrastructure will also become a problem because the net isnt really up to it in most countries. Atm the companies that own the power net is kinda waiting with the big investment into their networks hoping someone else will pay for it.

The recycling still is a problem, Tesla for example is just recommending old ones for other uses like storage, which they arent really perfect for.

Just saw an article stating that current batteries can be recycled completely to get the RE’s out and reused, that they don’t degrade

We could maybe use more recycling capability, no?

ELB2001 t1_j4w9y43 wrote

They can be, but nobody is really doing it. Cause it's cheaper to just buy the materials.

A lot of batteries are shipped of to be recycled, but aren't really recycled.

Some recycle a bit for pr purposes. The government's have to force them to do it, else it won't happen.

This is outdated information. There are multiple companies working on it right now. Redwood Materials is currently constructing a $3.5 billion dollar recycling facility near Reno that will produce enough materials for 1 million E.V. batteries by 2025 and 5 million by 2030. And that’s just one plant from one company. The company is also finalizing plans for an east coast facility as well.

LifeIsARollerCoaster t1_j57ndtp wrote

All your information and reasoning is incorrect and outdated. RE is not actually rare. It’s just the name for that type of elements. Because of demand there is increasing amount of mining that will come online for those materials.

The batteries are not going to get thrown out. lots of recycling is already happening and a lot more will happen as more EV cars start aging out. For any recycling to be successful, the product that comes from recycling should have enough value to pay for the process of recycling and that is certainly true for EV batteries.

Maybe stop recycling your outdated talking points.

Have you heard about the liquid battery that someone just developed? I remember reading a story about it on Reddit about 3-6 months ago, the tech was basically a rechargeable liquid that you fill up your battery with, when the charge runs low it can be swapped out for freshly charged fluid at a filling station or recharged at home or work or wherever. I thought the whole concept and tech would be pretty revolutionary as it’s combining the low emissions of an EV with the convenience of gasoline style fill up. There was no word on how expensive the liquid battery fluid was to produce or how bad it is for the environment in terms of the inevitable spills that would happen. It was one of those things where I thought in 10 years it will be the norm and change the way we live or we’ll never hear anything about it ever again.

It's extremely low density. Not suitable for a car.

Similarly there was a battery swap battery that was an Aluminum metal battery. Amazing range. But required specialized facilities to recharge. So you would have to battery swap which is complicated and expensive.

The problem is that for most people, just plugging into their garage power outlet is the cheapest and most convenient system. (I'm not one of those people since I have no garage. But you design around the norm, not the exception.)

Vol_Jbolaz t1_j4t8pai wrote

That is probably the case.

I was hoping for hydrogen cars because they can be refueled quicker than recharged.

Toyota has also invested heavily in motorsport (most Japanese brands do), and EV cars will kill motorsport. For now, GR can continue to push forward with hybrid power plants in motorsport, but that will come to an end soon.

Why EVs will kill motorsport?

Huxley077 t1_j4vdcxr wrote

Because different environments usually had to be "tuned" for. Things like elevation, air density , humidity, air-fuel ratios etc all had to be fine tuned for each race location.

Now...that doesn't exist. This, alongside electrical motors having little variantion in a highly regulated sport ( racing leagues have strict limits to hardware and design to help keep the the racers equipment about the same, emphasizing driving skill over hardware ).

It weakens the competitive aspect, though doesn't "kill" it outright

anengineerandacat t1_j4uyezl wrote

Wouldn't kill it but... a good chunk of that experience is the incredibly loud noises of what only a combustion engine can muster.

EVs have their whine but IMHO it's not the same.

That being said Rally is already on it's conversion over and F1 has hybrid systems too so it's just a matter of time.

Suspect endurance races will end or be highly dependent on battery quick releases of some sort.

I couldn’t help but laugh at this. “We like race because car go BRRRRRR” It sounds ridiculous, but you’re right.

Maybe they could keep our monkey brains excited by adding fake engine noises like this Dodge EV muscle car.

Vol_Jbolaz t1_j4vsona wrote

There are a few reasons why I think motorsport will (and should) change:

  • The differences between different EVs will be reduced in any balance of power to basically make it all a one-make series. You won't have a front-engine straight six all-wheel drive car, racing against a front-engine V8 rear-wheel drive, against a mid-engine V10 and so on. There won't be multiple solutions to solve a problem, it will just be different manufacturers making the same solution. (This is better for showing off which driver is better, but in that case, you could just do sim racing)
  • Endurance racing will be over. You can't recharge fast enough to make it reasonable. And since there will be fewer parts to fail, there won't really be any endurance.
  • F1 today is just a few teams that do everything they can to break the rules even though they have clearly better cars than the rest of the also-rans. It is too much money, and too much special dispensation given to Ferrari. It is too corrupt and isn't good racing. It will easily change over to EVs and people will think things are great, but F1 is a mess today that isn't worth watching. It will still be a disgraceful mess later.
  • Grassroots will be dead. Today you can buy a car that one of the race cars is based off of. You can modify your street car in different ways. You can go to track days or enter little MX-5, Rallycross, or TCR races with cars that you've modified and tuned. You can't change much about an EV. They will all be pretty much the same.

We do need to move beyond fossil fuels and polluting hydrocarbons (renewable ethanol). But it will be sad to see motorsport fall into an obscure little hobby that will never recapture its old glory.

oneMadRssn t1_j4vp6bl wrote

I don't really understand this reasoning. Both hydrogen fuel-cell cars and EVs ultimately use an electric motor as the drivetrain. The difference is energy storage. Of course in-house designed batteries would be optimal, but generally lithium batteries and controllers are available off-the-shelf. So at least some of Toyota's investment into electric motors and the related controllers would still bear fruit with an EV, and they have the cash to go get batteries on the market until they can spin-up their own in-house solution.

So what is the problem?

Dioxid3 t1_j4wt1pf wrote

There is another catch: they heavily invested in hybrid tech.

I was shopping for a new car, and realised Toyota has no PHEVs. Chatted with the salesman and he claims it’s Toyota wanting to keep the prices low by not sinking a 10-15k battery into the car.

In a way it makes sense, the NiMh batteries they utilize hold barely a few kWh, but I am sure they are a lot more replacable and cheaper. But I am sure part of it are the sunken costs.

It does help with emissions too, being able to drive full electric in rush hour. But it won’t be long until that ICE kicks in.

Toyota is an oddity from supply chain and manufacturing perspective, so it is hard to doom them for going against the grain.

Meh, I don't think they're wrong.

I'd go for hydrogen ICE if I could alter a slider setting on the game, and we'd get an abundant pure water resource for our Civ.

Anyway, it might take a lifetime to advance a small space. o7

The correct ICE fuel would be biofuels... With genetically engineered plants increase yield. We already have plants designed that would roughly replace 25% of existing US fuel consumption and make ICE engine emissions almost entirely a moot point. I get my 25% number from working back from the 50million acres currently used for corn and soy that are grown strickefly for biofuel (both are terribly inefficient compared to the possibilities)

See lipidcane and lipidshorgum. Which currently yield about 10x the oil of soy and double the ethanol per acres relative to corn from one crop.

Pretty much all gasoline vehicles can be converted to ethanol...and biodiesel is in many ways superior to petroleum diesel.

Hydrogen is one of the worst ICE fuels in everything except emissions.

Also opposed piston diesels can do 50% better than next generation ultra stringent emissions standards...so again why no traction on real solutions?

Ethanol and biodiesel do not solve the global warming problem. They were never a solution, only a temporary relief measure.

gh0stwriter88 t1_j4x6tug wrote

That's a bald faced lie. Also people produce emissions... If you hardline everything to that point...

Emissions on modern gas and diesel engines are ultra low except for CO2..... And this can be completely recovered via carbon cycle so long term will nullify thier carbon footprint (within a growing season, 1 years worth of automotive CO2 is insignificant as a load to the ecosystem.... constantly adding more is not).

Hydrogen is absolutely incredible for efficiency, reliability, emissions...it's great at nearly everything except energy density, which it's absolutely God awful at. Unfortunately energy density is by far the most important aspect of a practical vehicle, because nobody wants to drive around in a tanker full of literal rocket fuel just to have a range beyond a hundred miles. There's a reason the space industry has all but abandoned LH2. I can see it being an incredible alternative to battery storage at a utility scale, but not at a vehicle scale.

Though you are correct in the energy density being bad, it's also horribly inefficient to MAKE it. The work and power requirements outweighs the benefit is a other draw back

Right, because they aren't ready to sell EVs yet, not because they want to cell ICE cars forever. They literally only have 1 fully electric vehicle across their entire lineup.
