Whenever I buy parts for my regular gas car the parts site asks if it’s PZEV or DOHC. To make matters worse the PZEV version is also DOHC (dual over head cams) as far as I can tell. And the VIN number doesn’t say if it’s PZEV or not. It’s not on any of the paperwork I got with the car either.

Ah, I see. I googled PZEV, and apparently all it means is that it isn't releasing gasoline vapours - other emissions don't matter. So it's essentially just an ICE engine car that's not super polluting. It has nothing to do with EVs apart from being misleading in its name (perhaps on purpose?).

>I googled PZEV, and apparently all it means is that it isn't releasing gasoline vapours - other emissions don't matter.

No.

PZEV means partial zero-emotions vehicle… it is just STAR-STOP.

When you stop, the car shuts off and when it’s off it isn’t emitting anything. That is what it means.

It’s a total scam. Subaru was the first to put a logo on a US government mandated requirement (that made no sense).

I don't see anything in your comment history that would indicate a strong engineering role. Mostly political engagements really. You haven't said anything useful on this thread regarding TFA and it's content. Listing your credentials while making obviously false and dismissive statements is not good faith discussion.

lol… “I checked your post history and made bad assumptions” is the most Reddit Detective vibe I’ve ever seen outside of Reddit :D You own an EV right?

I'd have to agree with the "Redditor Detective" here. I've asked you a lot about your statements and all you basically said is "i know shit".

The redditor comment here is sort of a projection. Kind of like ..a redditor mod.

It's unfortunate that there is huge interest in prolonging lithium battery life because it's an indication of products with hard-to-replace batteries.

protected lithium cells are fairly save and easy to replace into devices designed for them. Lifepo4 cells similarly.

We need more product engineers out there fighting the good fight.

I think that's just sun+charging, not wireless charging specific.

I switched to wired charging with the phone mounted in the same spot and the heat issue went away. Wireless charging produces a lot more heat than wired.

That's really quite interesting. I know the wireless charging uses more power to deliver less power, so there's heat generation due to the loss of power in the transfer (I'm assuming that's how it works).

But, I figured that the battery would heat up more the faster it's being charged, and so wired charging at the same wattage would heat the battery more than wireless charging.

Must be a lot of power->heat transfer loss with wireless charging.

I don’t think that sounds right. My car was never offered with start/stop tech. Unless maybe they ask regardless of whether the car could even have that option… hmm.

PZEV does not have to turn off the engine at stop, that's not part of the criteria for that label. The label is about emissions.
