Toyota already admits that they are behind on their battery technology, despite having decades of opportunities to improve and innovate with their hybrid models.
Now they want to double down on their atrophy by effectively throwing their money away instead of investing in the future?
On the surface, this does not sound like a good plan for long term growth and profitability.
Someone told me they bought big into hydrogen powered vehicles. Seems they can't let it go.
Seems like they know first hand about "wasted investment" then.
Which they seem to have turned into a sunk cost fallacy.
"Well, we've proven to ourselves that we're incapable of investing without it being a sunk cost that we are too petty to let go and will fight tooth and nail to make profitable... So let's just skip investing in much of anything new ever because we're nincompoops. If there's no guaranteed profit, why invest?"
Japan has no lithium to mine. So hydrogen is the best option for them. While I understand this for Japan, there’s a big world out there where Toyota is a market leader… for now.
Credits need to be abolished. It just lets polluters keep polluting with no incentive to change.
Or at the least, they should be more expensive.
They're not backed by reality
Honestly this is the only thing that will work. You’ve got to speak their language. Fines aren’t a deterrent unless it REALLY hurts.
Unfortunately credits are totally fake. "So you have land with vegitation you already plan to conserve or farm? Let me help you make money on that and pretend we are saving it."
More evidence that carbon credits are indeed bullshit.
You can't fucking buy your way to environmental benefit.
So, I understand what Toyota is saying. I'm not sure I agree, but I get it.
Simply put, until we figure out a good solution to the battery problem, EVs are kind of at a dead end. They are about as good as they could be with current technology. There's a big push right now towards better energy storage tech, aka battery tech, for EVs and beyond (everything from cellular/mobile/device applications, to EVs, to "grid scale" storage).
The problem is basically twofold: first, limited energy storage. This is compounded by fairly slow charging... Second, current lithium tech used in EVs tends to be rather.... Flammable. Specifically, the most common chemistries are pyrophoric; aka, they burst into flames on contact with air. .... I'll emphasize that pyrophoric battery chemistries are commonly used in just about all consumer goods. This includes every Tesla, and every cellphone.
The only reason that your phone doesn't spontaneously combust in your hand is because the batteries are sealed so no air can get at the chemistry. The issue with Tesla's EVs is when one cell's seal fails, and it combusts, then the chances that adjacent cells will have their air seal compromised, dramatically increases. This can quickly lead to a chain reaction of failures.
Current research is ongoing into batteries. The golden battery for EVs will have, fast charging, high discharge capability (also known as the "C rate"), similar or better energy density to current cells, and longer charge/discharge cycle life. Since we're already comfortable giving pyrophoric batteries to the general public to carry around in their pockets, I don't think anyone is focused on eliminating that, but, if they can, while achieving the other goals, so much the better.
Other battery chemistries exist that are not pyrophoric, but they lack the energy density of their pyrophoric counterparts. One notable chemistry is LiFePO4, which, by sacrificing some energy density, you get much longer cycle life, and no pyrophoric materials.
Solid state batteries are being researched which should extend cycle life significantly if it can be achieved as a "commercially viable product" (which is corporate talk for something that can be mass produced). Thus far, while sold state batteries exist, they're either done in very small batches, and are very hard to produce, or, they simply don't have the same, or similar, energy density to the lithium/cobalt cells that currently dominate the market.
One alternative is hydrogen. Hydrogen fuel cell technology isn't perfect, with a loss of about 20-30% IIRC, from the energy in vs the energy out. The benefit to hydrogen is that it can be stored, highly compressed (a large volume of gas in a relatively small container), and it doesn't degrade or go bad, so it can be stored indefinitely, aka no significant loss over time. But hydrogen is a far more dangerous material than lithium/cobalt, and a tank rupture from a full tank of hydrogen in an EV, could create an explosion of significant size. It's far more dangerous than the pyrophoric batteries. For more information, see: Hindenburg.
Other alternatives exist, but generally are not being used in EVs for various reasons. Among these are RITEGs. An RITEG outputs a consistent and stable power flow indefinitely, even a relatively small unit could be used to power a vehicle, with a small buffer battery, for upwards of 40 years without needing to "refuel" so to speak. Possibly longer depending on the fuel used. The reason they're not considered is right in the name. The full name for an RITEG is "radio isotope thermal electric generator". Aka, nuclear. The unique thing about an RITEG is that the power output is dependent on the differential between the heating provided by the fuel, versus the temperature of the surrounding material (usually some sort of passive heatsink). They're very safe unless the seal is broken, in which case, you need Hazmat to clean up the mess. Their energy conversion is very very low. The power is stable, but only a small amount of wattage can be generated. It's constant, but it's a small amount. So the presence of a "buffer" battery for acceleration (and most driving) would be required, and often you can get more power from a small solar array, dependent on the weather. I like the idea of RITEGs, but more as a home generator type option, where you could bury one into the ground and dissipate the heat geothermally. No options exist for this and research into thermal electric tech has been stalled for many years. Nevertheless, I think it's awesome. The idea of having a mostly solid-state, base load generator in your back yard, seems like a really good idea, but nobody has done it, since IMO, the regulations would be a nightmare.
Anyways, the battery problem outlined here is what we're all waiting for... A commercially viable product that is on par with the current battery front runner, lithium/cobalt, for energy density, while having a much higher cycle life and a high "C rate".
Hydrogen is NOT a viable option for consumer vehicles. Energy storage is not dense, it is barely more efficient than an ICE, and it is also very flammable because it is highly pressurized H and a large battery. They may be fine for commercial vehicles but there is not a market for them for consumers. That is why Shell is closing up its stations in CA and why Toyota is discounting the Mirai significantly while also giving lots of fuel up money and it is still not enough to do much for demand.
As for solid state batteries, they are already in some BYD vehicles and Toyota itself is claiming that their solid state battery that will offer 650 miles of range should be in cars by 2027.
As for current batteries, the limited storage is not a real issue in 99.5% of cases. Over 99% of trips are under 100 miles. There are quite a few EVs now that can get 300 miles which is more than enough for 99.9% of trips. The comparatively slow charge for fast charge stations is also not much of an issue since few people can drive that long without taking a half hour break (although several models can add 200 miles of range in 15 minutes). The current major hurdle for that charging is working stations that charge at a decent speed. And what about the 99.9% of times when you do not need fast charge? We need to make level 1 chargers significantly more available. The average American only goes a little over 30 miles per day and sits idle for 22-23 hours. If it can be charging for a large chunk of that time, even at level 1 speeds, you are looking at 70-90 miles added per day. We need to offer huge tax incentives to apartment owners to install them in parking spaces and incentives to either install smart panels or upgrade panels to 200A. Cities should also start putting slow chargers in their downtowns where people park.
The overall issues with EVs are largely not the batteries themselves, but the infrastructure surrounding them.
One alternative is hydrogen. Hydrogen fuel cell technology isn’t perfect, with a loss of about 20-30% IIRC
You don't recall correctly: The efficiency of Hydrogen, from solar cell to the wheels is 26%. Electrolysis is highly inefficient and compression and chilling of hydrogen is very energy intensive. Meanwhile, EVs are at 70%.
You are right that batteries kinda suck due to their energy density. However with EVs you can buy today you can still commute every day without noticing any major difference to an ICE car. You can also do long road trips, even in a small car, albeit slower. (Source: did both)
Toyota is claiming to have a 750-mile solid-state battery that will be commercially available in 2027. https://www.reuters.com/business/autos-transportation/toyota-roll-out-solid-state-battery-evs-couple-years-india-executive-says-2024-01-11/ If this is true, then the battery "problem" will be a moot point.
Toyota has invested heavily into hydrogen, and so are against electrification
Hydrogen would be cleaner in the long run, too, wouldn't it? Since you wouldn't need to mine lithium for batteries and such.
Yes but where is the hydrogen coming from? Also hydrogen cars are less efficient than battery powered EVs.
It wouldn't. Hydrogen production from any source is extremely power intense. Especially so from water. The amount of energy wasted on hydrogen production is easily offset by battery production and recycling. And that's not even accounting for hydrogen tank production, which is another hell hole.
Prius is one of the most popular selling Toyotas since it's debut, either they're just being obstinate about EVs or they are really invested to the gills on their Hydrogen fueled car lineup.
You would think at least one of their execs would have learned about the sunk cost fallacy in basic econ.
Honestly it's quite amazing how prone we all are to falling for the old sunk cost fallacy, that fallacy and confirmation bias have to be the two most popular cognitive issues for us as a species.
Consumers like the Prius because of the addition of the battery and electric motor.
Toyota likes the Prius because it still contains and ICE engine, which they want to keep selling.
I'd rather waste my money on a car from a maker with vision. This is in line with their move to TX. Too bad.
JFC we need a carbon tax. All these posts claiming ICE is better than EV lol. Burning fossil fuels kills 250,000 people a year in the US alone. It’s a 25% efficient process. ICE engine has 2000 moving parts while EV has 20. ICE is 20x most likely to have a car fire than EV and far more deadly. This list goes on and on.
That's funny because I'd rather spend my credits on something other than a Toyota.
