Another potential source of references, more in line with your specific example here, would be from restaurants, shopping centers, rest stops, etc, advertising free "EV charging" for customers, with that being a service to exclusively charge the 12V battery.

Surely if you're not the only human on the planet using this language it's easy to find a single reference.

Again, please provide a reference to charging the 12V battery inside an EV (exclusively) as being referred to as "EV charging". Even colloquial references like from auto reviews in Car and Driver or Motor Trend would be acceptable.

Along with an explanation for why you included "EV" instead on just "vehicle charging" (as all vehicles have low voltage battery systems).

Otherwise we can just acknowledge you're a troll using unconventional and disingenuous language because you're too insecure to admit you're wrong.

EV charging is charging the EV battery. And 12V batteries aren't EV batteries. They're used in ICE vehicles as well. Their name doesn't change depending on use...

Haha. Charging 12V batteries is not an additional benefit. It's additional environmental destruction for no reason.

And again... 12V batteries aren't EV batteries. By definition.

EV charging is universally recognized as charging the EV battery. You don't get to invent your own language because you're too insecure to admit you're wrong.

The comparison is to the proposed solar farm.

The parking lot canopies are additional infrastructure. You claimed savings on simpler, cheaper electronics that would charge 12V car batteries.

That makes no sense whatsoever. It's such a moronic idea that even if it existed no one would use it to charge their 12V batteries. The energy savings it would provide would be absolutely dwarfed by the environmental impact of it's manufacturing and construction.

But now you're saying it's also going to have traditional electrical infrastructure to feed power into the local grid and presumably do useful stuff like power homes and charge EV propulsion batteries, but that goes against the whole supposed savings by not needing any such electrical infrastructure...

I don't think you even know what you're talking about at this point.

The above confirms exactly what I already stated.

You can "jump" an EV with a dead 12V battery (happens to Teslas all the time) to turn it on, but you can't drive off the 12V battery.

Charging the 12V battery independently doesn't extend range in any meaningful sense.

I'm an electrical engineer and you clearly have no idea what you're talking about.

Not for an EV. There are no EVs that run on 12V. They still have 12V batteries for accessories and such because it's considered an inherently safe voltage (low shock risk) and so they can save money on wiring and use chassis as a ground.

The propulsion system uses higher voltage batteries and regardless, the output voltage and current from a solar panel can vary with light intensity. You need conversation electronics.

And solar on an EV is basically a gimmick. The minimal extra range relative to the additional cost is absurd.

Pretty predictable how much push back this is getting.

Until we have fusion plants that can be installed in one story buildings or underground so not to impact anyone's view and within a 1/10th acre lot we're pretty doomed to continue using power sources that are far more detrimental to the environment.

The transmission loses are pretty low and now you're talking about a lot more power conversation hardware.

You're not going directly from whatever voltage a panel array outputs to the car battery...

And I haven't seen these often in northern climates. They might make sense for small parking areas or only the perimeter of larger parking lots. Otherwise seems like they'd make snow removal a nightmare.

When I was a kid they even had Catholic mass on the West side in French. But don't think that's a thing anymore. Growing up and playing hockey in Manchester (Flames) was a trip as the coaches would tell yell at us in French if they got really pissed.

It does change the end game in that it can't just be continually more intermittent sources...

That is without some other energy storage solution which negatively impacts the economics and most of which have their own environmental issues.

Meanwhile nuclear works day or night regardless of weather conditions...

At very cold temps they're not much better than resistive heating...

Most installers want you to have a backup system for colder temps so it's a lot more cost and maintenance for somewhat lower overall energy costs.

Though you do get AC with it if you were planning on that anyways.

I like Valvoline for inspections too because as you said, quick. And they won't do much repair work outside replacing your windshield wipers so less motivation to try to get you for extra money.
