Featured Solid state battery in 2022 prius

I’d be interested to know how they fixed the dynamic response particularly in cold weather. Maybe they’ll slap a NiMH battery pack in like they did with FCEV (Mirai) to fix that dynamic response.

Hopefully they’ll pair it with SiC electronics for a completely air cooled car.


Unsupervised!

Not to be too much of a damp blanket but

Its conflating two different things. Toyota is indeed developing solid state batteries both on its own and with panasonic. They hope to demo the battery prototypes in a car next year, but according to panasonic the tech was at least a decade away from being better than lion last year. That means a low production vehicle at least until 2027.

Toyota is building a new platform with daihatsu and subaru, and this has been accelerated in terms of volume according to new toyota/subaru press releases. Its this new platform, likely that they are talking about in 2022.

pie in the sky. although they have been working on it, no one can predict if and when it will pan out, not even engineers.

we'll get higher tech batteries when we get them. wishful thinking won't make them come faster

 

If you want faster charging on AC, then you need the faster charger. The battery chemistry is just going to dictate the maximum rate it can handle.

 

There was something I was reading (Scientific American or New Scientist - maybe?) where manufacturers were considering using a combination of solid state and batteries - to use the strengths of each. Fast charging came into the conversation, but I can't recall the details - plus I didn't have a full understanding of what they were talking about. My understanding is that solid state batteries are likely to still be Lithium based - at least in the early days, just using a solid electrolyte, think Magnesium was being worked with too.

With the e-TNGA, this article says " ...In total, Toyota plans to roll out six models on the e-TNGA platform. The list includes the compact crossover mentioned in the previous paragraph, a medium crossover, medium SUV, medium minivan, medium sedan, and a large SUV. Suzuki and Daihatsu have been confirmed as development partners on the compact crossover ....".

• Canadians may have other voltages and currents available.
• I've seen 48A claimed for direct wiring vs NEMA plug.
• J1772 is rated up to 80A, we have one in Huntsville.

Yes.

Public L2* chargers aren't actually chargers, they are just a physically oversized EVSE. It is car's onboard charger doing the charging. The public EVSE might limit that car's charger because of the limits of its electrical supply, or the owner charges by time, and wants to defraud EV owners with faster chargers.

* I'm assuming this is AC. Officially, there is no longer a L3 by the SAE. It is AC L1, AC L2, DC L1, and DC L2.

Solid state just refers to the battery not using a liquid(or gel or goo) electrolyte, not the type chemistry. The solid state batteries under development are Li-ion. So they aren't a solution for those worried about raw material supplies.

 

I think it came about because of the differences in how the charging is handled.
With AC charging, the job is handled by the charger built into the car, and thus it becomes a limiting factor on charge rate.
With DC, what people call the charger is truly charger. So the only limiter in the car is the battery itself.

I don't think there is any DC L1 chargers in use within the US. Telsa's local Superchargers might be rated faster than the terms definition. China might have some. It may not be much faster than AC L1, but you get a wider selection of what charger to use when it is outside the car.

 

i'm still trying to figure out 'regular', 'premium' and 'super hightest'

 

Where does Ethyl fit in?

 

I think that regular is when your car dumps its exhaust at consistent intervals

Electric Vehicle Charging Levels Explained

I guess some of the CHAdeMO and CCS units out in the wild might only be DC Level 1.
Superchargers now exceed DC Level 2 definitions. The very first ones might have been 70kW. The Urban Superchargers have a 72kW max.

Is that like whiskey and whisky?

 

A little history - ethyl is short for
tetraethyl lead gasoline
the additive for lead gasoline. Its mostly gone now because of the unhealthy air pollution.

Probably should just say DC and rate.
Aren't many the newer DC chargers much faster than the 200A 400V - 90 KW max.

Tesla v3 are 250 kw, I think it peaks around 700A, which only the model 3 can currently take advantage in the tesla stable. The software conditions the battery when it approaches to supercharger so that charges can be as fast as possible. Rumors are the x and s will get maxwell technology batteries next year (300 wh/kg dry electrode) and be able to use them at these high current levels for new cars.

Combo plug now are being built at 800V x 450A, but most will be 400V x 450A or 175 KW, the max standard for that and changedemo is 1000V x 400A or 400 KW.

For these high rates its likely batteries will be charged at the charging stations and discharged into cars to buffer the grid.

Chinese standards are going for 900 kw

Yup, remember it well. Was just being silly.
