The Answer To Our Problems, EV's

Perhaps he's studying. Never know.

Yeah that's a good point. If it was still functional why would you take it out of the car.

 

Yeah rail is fantastically efficient at moving freight. I think electric semis are going to be a hard sale. A semi that needs more hours charging than hauling is a poor investment.

I don't think that'll ever be practical for a semi. Swapping a battery would just take heavy equipment. Charging them will be much more difficult

It's cheaper just to run what we have now. And likely better for the environment. Your talking half of a 400 KWh at least just to charge one battery if you have a fleet of 30 trucks for a medium operation. That's 12 MWh you need your own small power plant to charge all of that.

 

Let's test you. What formula represents the power of a 3-phase power system?

I've posted this many times, and it would be easy for you to get the answer either from the linked video or another source. Once below 80% capacity, EV batteries are no longer viable for use in an EV, but they have 10-15 years of life left as energy storage, before recycling.

 

If they work then why would you take them out of the car?

So they are destroying perfectly good used electric cars to save a millisecond or two of power for the grid? Sounds like a scam to price normal people out of ever owing an electric car. If think the battery would have more value in the car unless they can't give the stupid things away.

Sounds like less than a drop in a barrel. Why rip apart cars to store about 5 seconds worth of energy in second hand batteries? It doesn't make much sense.

Sorry to be the one to tell you things but electric cars use fossil fuels too your just moving it around you aren't reducing anything. Batteries are charged mostly by burning fossil fuels.

 

Test me on what?

Brand new they only have 80% capacity. You can't charge them all the way up because it'll damage the battery. So maybe 60 % capacity and that'll likely be in 4-7 years as batteries rarely last longer.

I still think it would be more useful in a car rather than storing a millisecond with of energy for a power grid. And let's not forget all the crap that a car is made from has to be despised of. This seems extraordinarily wasteful to pretend you have backup power.

 

If you took all over the batteries out of all of the cars out of the entire State of California and use them to store energy or just the city of La they'd probably be empty in about 4 minutes.

What good is this?

 

Four minutes? Link please

Check out this photo, and the accompanying article. Each of those shipping storage pods is a battery storage unit, with banks of retired EV batteries. During the day, this solar power plant can provide power for a small city, while also charging battery banks with excess power. At night the banks provide the city power from the batteries. These EV pods could also be used in conjunction with wind energy.

I don't have a link I did math. Very simple math you study the electrical engineering but you don't know basic arithmetic.

why rip apart a perfectly good car for a very very very low amount of electricity storage?

if you just built the power plant first it would be cheaper second you wouldn't be throwing away perfectly good cars and third it would be more than a few seconds worth of energy. What the hell is the point of this that?

Not interested in the scams and shams. There is not enough battery on the planet to make a difference. You should know this if you're an electrical engineer

 

Rail is not the answer. Where did you come up with that conclusion? E semis will never be a viable solution for transporting goods in the US.

 

What size city is that? 25 megawatt hours of stored energy means that these batteries can supply 25 megawatts for 1 hour. The city of LA requires approximately 3,000 mega watts on average (21,600 gigawatt-hours (GWh) per year). The 25 megawatt hour stored energy would be gone in approximately 30 seconds which is even less that @Polydectes calculates.

I wanted to be as charitable as possible

 

You'd better research more thoroughly and make a more informed post.

If it can be done for a car, it can be done with a truck.

 

Who said anything about powering all of L.A.? This system is easily net-metered, and can be installed anywhere. It's best to install somewhat near some end users to help Utilities with voltage loss, which is an added PLUS for the utilities. There are a lot of renewables in and around Los Angeles. The city has a goal of 100% Clean energy by 2035, and 100% Renewable by 2045. That will take a coordinated strategy of a lot of technologies. I really like the new monorail (BYD Skyrail) they are considering.

 

Will you tell me how long this amount of energy will last before all these batteries are depleted.

 

I don't doubt that it can be done it just isn't practical.

You can probably replace the engine transmission rear axle and all the tires on a truck every time it stops it's just not practical.

I'm sorry if they were practical we'd have been driving electric semis for decades now.

 

That goal is a joke.

 

Obviously it can be done with a truck. Tesla's already demonstrated it.

But heavy duty has much more severe limitations that make widespread adoption of EVs even more absurd.

Sure, there's an EV bus. Big deal. If there's one application that works in heavy duty for either alternative fuels or EVs, it's municipal fleets. Things like buses and garbage trucks. Limited range (a garbage truck, for instance, usually puts on about 15 miles a day) and centralized refueling (we made garbage trucks that would run on landfill gas- free fuel for the landfill operator).

It's really easy to do the same thing with municipal buses. This announcement doesn't amount to much in terms of game changing.

And probably the factor that will ultimately kill EVs in heavy duty is that it's impossible to write a regulation that mandates them.

Light duty is regulated on a chassis basis, miles per gallon or it's exact mathematical inverse, CO2 per mile. Those limits involve the entire powertrain and, if practical implications are ignored as EPA is currently doing, are theoretically possible and can be phased in.

Heavy duty (>14,000 lbs GVWR) is regulated on an engine-only basis based not on miles, but rather on work output. Internal Combustion Engines, no matter how big or small, automatically have 30% of their exhaust as CO2.

And again, the inherent weakness of EVs is they suck at doing work. Check and Mate.

That's why it's never going to translate broadly to trucks.

 

And the insanity continues. Especially in the woke state of California. When will the "woke" wake up?

The Chinese again are using the inexplicable obsession with green solutions to the global warming non issue of the US to help us negatively affect our economy and futures of our children.

California needs to act. They have the most polluted cities in the US, because of the inversion.

 

What is the source of that? What cities are those? What inversion? The air in California has never been cleaner. And that is not because of green energy.

 

Top ten in almost every category.

A rather unfortunate consequence of having so many people wanting to live in those places.

 

The undefined "particle pollution" is from wild fires. And if the EPA were right about their predictions everyone in Northern California would have died a few years ago.

Where is the quantification of the levels of ozone?
