re: The more you know about EV the more you wonder if we were really ready for this change.

Can you point out where I've ever said I support mandates or forced adoption. I live wholly on the engineering and technical side of all this shite. I'm only here to shoot down incorrect talking points people get from Twitter and Facebook.

I’ve heard EV chargers require a 200 amp service? Is this correct?

In all seriousness, I'm not even sure that would work. Maybe with that Honda, but not just any generator off the shelf. These units are very frequency sensitive and most portable generators have very unstable frequency.

Yeah, pretty much unless you want to essentially trickle charge it all the time. Technically, you only need 50 amps but that's going to obviously take up most of a 100 amp panel. To put this in perspective. I run mine off a 100 amp subpanel in my garage but that's fed of my main 300 amp panel.

200A is really what you need for a level 2 home charger.

they intercept the DC before it's converted to AC and directly DC charge the EV off the PV to avoid the loss.


Only thing you're accomplishing here with your DC charge is charging the 12-volt battery to start the car and run some accessories. You are pissing in the wind with this fantasy harbor freight or some other retail outlet inverter theory of yours. You are not "intercepting" jack shite when it comes to the main battery...like I said, maybe 1 to 2 miles per hour if you're lucky.

What EV has a 12V battery to start the car?

This is where I can end the conversation, you have absolutely no clue that EV's still use 12v standard or 12v lithium for accessories and aiding in the DC-DC high voltage starter sub system. You don't even own an EV do you? If you did, you would know there is a second battery in that car. Wow.

we are not ready for the change. It needs to be an evolution not a revolution. Eventually the technology will develop to a point that it will be as good as gas.

Lets look at your entire quote and not cherry pick.

12-volt battery to start the car

Yes my wife drives a model 3. On top of that I have a log in to Tesla data repository because I've done a shite load of finance deals with them and continue to monitor TPO assets for the companies I've done the deals with.

You said to start the car. IDK what to tell you dude but that's retarded.

This dude thinks we can deploy airbags, electrical and other critical components of an EV directly from the 400-volt main battery pack and NOT need a 12-volt Lithium second battery in EVs? I'm floored. I hope he didn't pop that 12v battery out and thinks he doesn't need it. 400v could kill someone if touched directly. Now I'm concerned for this dude's safety.

Its being forced going against basic market principles. It will create problems because of that.

I love new tech and old tech, but forcing EVs is a mistake. Central planners are far more social than economic engineers.

coming from someone who thinks they need to crank up that EV I find that pretty funny.

I never said "crank" come on baw. I used "start" in the sense to power the critical accessories at a much safer capacity of 12 volts. But going back to your original claim, you are not "intercepting" jack shite at 400 plus volts in any meaningful way with your store bought inverters and your little solar panels. Ain't happening even in your Google fantasy world.

EV?
quote:

There are a host of reasons why the Left is absolutely determined to force Americans out of their privately owned, gasoline-powered cars and trucks and into unreliable public transportation and costly Electric Vehicles (EVs), none of which have to do with “saving the environment.”


quote:

10 facts about EVs the Left doesn’t want Americans to know:

1. EVs are powered by fossil fuels. According to the U.S. Energy Information Administration (EIA), fossil fuel-based power plants — coal, oil, or natural gas — create about 60% of the nation’s electrical grid, while nuclear power accounts for nearly 20%.

2. The batteries of EVs rely on cobalt. An estimated 70% of the global supply of cobalt emanates from the Democratic Republic of the Congo, a country with deplorable working conditions, especially for children.

3. A study released earlier this year by an environmental group showed that nearly one-third of San Francisco’s electric charging stations were non-functioning. The population of San Francisco represents roughly two percent of California.

4. Supporters of the California law admit there will be a 40% increase in demand for electricity, adding further strain to the grid and requiring increased costs for power and infrastructure.

5. According to one researcher, the strain of adding an EV is similar to adding “1 or 2 air conditioners” to your home, except an EV requires power year-round.

6. Today, 20 million American families, or one in six, have fallen behind on their electric bills, the highest amount ever.

7. Utility companies will need to add $5,800 in upgrades for every new EV for the next eight years in order to compensate for the demand for power. All customers will shoulder this cost.

8. The average price for an electric vehicle is currently $66,000, up more than 13% in just the last year, costing an average of $18,000 more than the average combustible engine. Meanwhile, the median household income is $67,521. For African American families, the average is $45,870, and for Hispanic households, $55,321.

9. A 2022 study found that the majority of EV charging occurs at home, leaving those who live in multi-family dwellings (apartments) at a real disadvantage for charging.

10. The same study also noted that many drivers charge their EVs overnight when solar power is less available on the grid.

Once again, proving you have no clue how the hierarchy on a Tesla works.

your store bought inverters

It's a SolarEdge. They gave it to me test when I was on a TEP project and qualifying the new units for investors. I took one array off the existing Enphase IQ8s to put this on to try it out.
