Featured Lexus Self-Charging (no plug)

Where in the marketing of the Mirai do they call it a hybrid. Your talking about an entirely different vehicle from many moons ago.

 

When you go to the hydrogen station, can you choose to fill 100% renewable hydrogen?
No, you are stuck with whatever they have, and you'll like it. Buying hydrogen is just like buying gasoline. If I wanted gasoline made from Texas sweet crude because it has a lower carbon impact, I can't get it here. Instead I'm stuck with whatever the station has, and it might have tar sand source mixed in.

With electricity, much of the country has a choice about where it comes from. You want to use renewable electricity for your plug in, you can. You can even choose to install solar at your home, or even wind.

While you could use that solar to run an electrolyzer, you won't be able to fill your FCEV's tank without paying a huge price. The home filling CNG units ended up being too expensive and unreliable, and they only had to fill a tank up to a third of what a hydrogen car needs.

It was their FCEV preceding the Mirai; the FCHV-Adv. Toyota only gave up on using hybrid recently.

 

It was not it was an early development of the present Mirai. Recent, like 10 or more years ago.

 

Oops
Maybe another edit will take care of that

In the meantime, today's fuel cell technology is such that the car can run on hydrogen that has to be received through the hose getting plugged in every so often, or it can run on the battery, or it can run on both . That's just the honest reason Toyota references it as a hybrid. That's more honest than GM calling the Chevy Volt an (extended range) electric car .... an EREV. It's a plug-in hybrid .... just like today's menu of hydrogen cars. You can't refill their battery, without the hydrogen hose being plugged in once in awhile. You can't refill a Lexus rx400h without the gasoline hose being plugged in once in awhile.

The FCHV-Adv came out, and was available for limited fleet use, about 6 or 7 years before the Mirai. The Prius has a design cycle of 6 years, and there wasn't another FCEV between the two. Then Toyota was using HSD in combination with FCEV up to the Mirai being available to the public.

The use of hybrid for cars got discussed in the beginning of that 20+ page Mirai thread. It refers to power sources on the car, not energy sources. Otherwise, we'd be calling dual-fuel ICE cars hybrids.

GM defined EREV in a paper submitted to the SAE, and didn't deny being a subset of PHEV. Just like hybrid has full and mild.

Toyota didn't justify using hybrid with a FCEV. They slapped their FCEVs with THS-II and then HSD for marketing as the gen2 Prius was a huge success at the time.

If the Lexus battery is "self-charging" as it clearly says in the ad, then take it out of the car and place it in the driveway and let's watch it and see how it "self charges."

My guess is that we will only see it "self discharge."

A battery that comes from the Camry is a hybrid battery. There is no mention that the Mirai is a hybrid. Because it’s not.

 

Well surely you jest!

 

There's not a single statement in there from Toyota that said that the Mirai is a hybrid, just that they used a lot of the components from their high volume hybrid production in the Mirai (which is entirely true).

By using those high volume components it reduced the cost of the Mirai. A fuel cell powertrain doesn't even need a battery, it is better suited to a supercapacitor, but building an automotive grade supercapacitor would have increased the cost substantially, so they used the battery from the Camry.

 

It was enough for them to slap THS-II and HSD on their FCEVs. Wising up with regards to the Mirai doesn't change the fact that Toyota tried getting FCEVs, buses and cars, called hybrids.

 

Still never stated its a Hybrid. Just because it uses hybrid components does not make the Mirai a Hybrid. If they built the Mirai with airplane tires, does that now make it an airplane?

 

Do you realize you are arguing with Toyota on this?

 

Show me where Toyota markets the Mirai as a hybrid?

 

It isn't about marketing the Mirai. It is about what Toyota wanted to call FCEVs. That is, all of them.

They have backed down with the Mirai, as no one else in the industry went along with them, but they still feel the need to point out that the Mirai is using hybrid components. Yet the components they list are EV components. None of them are hybrid only, and are likely being used in their BEVs.

The only one that drew a line between FCEVs and hybrids was Toyota.
