China Has "Flash Charging" EV's

[MaverickDragon]

Here is a very informative video that I am sure you will not watch because you have already made over up your mind but for anyone else this is a great video about the truth on solar panels and other alternative energy.

Wow - You must know everything, except absolutely nothing about me.
I've been using solar power for the entire millennium, so I don't need to waste an hour and a half listening to someone tell me what I already know. I've designed and installed several variations of half a dozen systems for myself and neighbors, but I guess you know more.

How much real world experience do you have, other than watching a UTube?

Solar power is great until it isn't. In the southwest it works pretty well, but if you rely solely on solar a few days of clouds and it's a different story. That's a fact.

My power system is a hybrid, because despite the ability to generate more power than I typically use, without the grid backup I could be at risk of battery damage from undercharging.
The problem with solar is that it is dependent on the sun. While reliable for 4 billion years of power what isn't reliable is the weather on Earth.

On a clear sunny day my system can put out 4K+ watts and everything at my residence runs off solar generated battery backed inverter power as a separately derived system except for switched led lights and the high watt usage appliances like the dishwasher (heating element) and washing machine (direct drive has constant induction load current).
I've got 20 grand in batteries that are typically charged before noon.

I built a similar system for my neighbor. The problem is when 3 or 4 days in a row the sun is obscured by clouds, he has to run a gas powered generator just like everyone else with a stand alone solar system. I switch on a utility powered charger that costs me 10 cents a KWH instead of $4 a gallon.

Another neighbor took my advice and I built him a hybrid system, easily switchable between the grid and the battery backed solar. He never has a problem.

Extrapolate the cloudy week scenario to a large scale power grid without your rose colored glasses, where most of the power is coming from solar panels that go from producing many gigawatts to perhaps 5% or less of their rated capacity. That happens.
The utility load comes from batteries, and after 2 days, that's gone.
On day 3 so is the grid.

Did you ever work for an electric utility power company? I did.

There is a reason why a utility needs a large reserve of potential power that isn't always online, but of course you already know everything, except apparently not the concept of being able to accommodate unexpected peak demand, and surviving a generation problem without a major power failure.

China has 500-year plans.

The US changes its plan every 4 years.

Look who is focusing on oil and gas for short term profits and who is planning on a fossil fuel free future.

I am guessing solar does not work well when it snows. And that snow sticks around for 3 or 4 months.

At least with ethanol (and corn) you can store it for the winter and use it year-round.

The "video" highlights:

Oil is single use. One use ever.

Ethanol is one use PER YEAR.

Solar could be one use PER DAY.
Until it snows.

I have solar on my house and over the course of a year, My total power bill is about $200 for the whole year.

I produce way more power than I consume, but there are so many added costs to my power bill on top of the actual electricity I use. Surcharges, tax and so on.

It is true that I have to buy power from the power company when it’s dark but during the day, my excess power I make goes out to the grid and the power company buys my power at the same cost I buy it from them.

Make no bones about it. Solar kicks ass. I can attest to that. The big solar nay sayers are just trying to find a way to diss a good idea.

Those same people say we need to keep using oil for power while the rest of the world is putting down their shovels.

BYD Blade 2.0 batteries are noted up to 150KWH capacity.
To charge that battery so quickly, the BYD fast charger runs at 1500KW.
Most houses are 100KW to 200KW panels, just slightly less than 1500.

As @Mavster Mechanic noted, that kind of charging is ridiculously far in excess of the availability of any household panel.

The existing "fast" charger network by Tesla operate at 1/3 of that power level.

To be efficient at those levels would require significantly higher voltages or the cabling costs would be extreme. Watts = Amps * Volts and more amps equals bigger cables or overheating results.

After reading all these posts about super fast charging for EV's, the answer is not home charging, it's "fast charging" stations, former "gas stations". Just like we gased up our cars in the years past. Stop for 5 minutes to fill up.

Flash went the guy plugging in 1000v

He kind of left Mr. 400V in the dust, didn't he?
