Electric vehicles close to ‘tipping point’ of mass adoption

[Old Rocks]

Wong.
You are ignoring headlights, wipers, defrost fan, heaters, etc.
These thing are going to cut EV range by over 30%.
You are also ignoring the fact the battery weight will double the energy consumption on hills.

So, you are smarter than the engineers that obtained the facts that I posted from that site. LOL You "facts" stink because of there source.

 

[Rigby5]

LOL Post a link for that. You have proven already that you pull shit out of your ass, with zero credibility.

There is no point or need because we all know that the theoretical efficiency of an electric motor depends on letting it reach highest possible RPM.
When you let a motor reach high RPM, the internal resistance becomes highest and the least amount of energy is used.
It is when you bog a motor down at lower speeds that is has very little resistance, so is incredibly inefficient.
And in an EV, that is what happens constantly, as you stop and start.

 

[Old Rocks]

The faster you try to recharge batteries, the shorter the life span.
And at over $5000 for batteries, that is not viable.

No one has EV semi trucks on the road, and the only prototypes I have seen are not practical due to reduced cargo and recharge waits.
The EV planes were all animated simulations. There are none and likely to be none.

But you have a good point about trains, since they can easily use overhead conductors and don't need batteries.

The Tesla semi recharges does an 80% recharge in 45 minutes. It has a range with a full load of 500 miles. And companies like Freightliner are testing their EV semi's as we post;

Yes, Electric Big Rigs Are Coming—and We Drive Four of Them

From semis to box trucks, step vans to school buses, Freightliner has a test fleet of 40 rigs, with availability in 2022.

Gee whizzaroo................................ The Tesla S Plaid is so inefficient from a stop that it takes 2 seconds to get to 60 mph. LOL See that figure for regenerative braking? Tell me, how much gasoline to you get back when you slow for a stop light? LOL

Well yes of course someone with a physics degree is likely smarter than an engineer, but the facts are that people have been trying to make EVs for over 20 years, and they have never yet proven very reliable, and are far more expensive. Resale of even a hybrid like a Prius is not very good, due to short battery life.

No one has any EV semis yet.
The images were all ICE trucks, with radiators and grills.
And that is because EVs cost too much and can't carry enough cargo.

{... While the diesel-powered Cascadia sells for somewhere in the $139,000 range, electric big rigs like this, depending on how they’re configured, can cost two or three times as much. ...}

Acceleration is inefficient, not a display of efficiency.
You can't have regenerative braking on an ICE because it does not weight enough.
It is the heavy batteries of an EV that allow regenerative braking, but that does not make up for all that weight.

LOL You are claiming a degree in physics? LOL You are a liar. No scientist that I have ever had any dealing with would make the baseless claims you have. And, by the way, Elon Musk does have a degree in physics.

"According to SolarReviews, the current batteries in Teslas are designed to last for 300,000 to 500,000 miles. After that point, the battery will likely need to be replaced. SolarReviews points out that a Tesla battery might still work beyond 500,000 miles, although with a reduced range per charge.Jan 3, 2021"

How Many Miles Will a Tesla Last?

How many miles will a Tesla last, and when should you expect to replace the battery in a Tesla EV?

And that is with the current batteries. The LFP batteries will probably go for a million miles.

So then how come the Tesla only comes with a 10 year battery warranty and 80% capacity?

BYD (Build Your Dream) EV buses fail in LA and Albuquerque.

BYD faces Albuquerque lawsuit

LANCASTER — The city of Albuquerque will take BYD Coach & Bus to court for failure to meet contractual obligations and delivering unsafe buses to the city, Mayor Tim Keller

www.avpress.com

{...
LANCASTER — The city of Albuquerque will take BYD Coach & Bus to court for failure to meet contractual obligations and delivering unsafe buses to the city, Mayor Tim Keller announced Friday.
The 739-page lawsuit comes after the city reportedly encountered numerous problems after the first few buses were delivered last October behind schedule, city officials said in a press release.
...
Albuquerque city officials say they have tried working with BYD Coach & Bus — a U.S. company that is a wholly owned subsidiary of its Chinese corporate parent — but the company continued to fail to meet requirements set in the contract with the city including delays in the delivery of the buses, and incomplete certification testing at the Larson Transportation Institute’s Bus Research and Testing Center, in Altoona, Pennsylvania. The city says the bus batteries run at only 177 miles on a single charge even though the contract requires 275 miles on a charge.
“As we work to move Albuquerque toward an environmentally sustainable future, it would have been a great step to have electric buses on the route, that’s one of the reasons we tried to make it work with BYD for a year,” Keller said in a statement. “Unfortunately, the technology they promised simply isn’t ready for this route. Our aim is to continue to eventually move all of our fleet vehicles to more sustainable models as the technology evolves. In the meantime, we are going to have to use more traditional clean fuel buses to get this project moving.”

Looks like another opportunity for Tesla or Arrival.

Hey Dumb-de-dumb dumb, no one is going to insist on everyone having an EV for quite a while. But there will be regulations that state after this time, you cannot manufacture an ICE. There are already such rules in other nations, usually about 2030 or 2035. By that time, the EV's will be less costly to buy, they are already longer lasting, and outperform ICE's. And they are far less costly to run, and require far less maintenance. Also, as production of gasoline drops from lack of demand, the cost per gallon is going to go up, and it is going to be harder to find a place to buy gas or diesel. The death knell for ICE's is sounding right now, and anyone that cannot see that is blind.

The only accurate prediction in there is increased government regulation by short-sighted leftist idiots.

 

[daveman]

From your "smart engineer" link (that you apparently didn't read):

Electrical accessories such as lights, windshield wipers, navigation systems, and entertainment systems require power and lower fuel economy.

Losses from accessories such as electric door locks and signal lights are minuscule, while losses from seat and steering wheel warmers and climate control fans are more significant.

In very cold conditions, auxiliary electrical losses can account for more than 33% of energy use in combined city/highway driving.

Unlike a conventional gasoline or diesel vehicle, which uses heat from the engine to help warm the cabin, all heat must be provided by electricity.

OldRocks has never heard of counter-EMF.

Roxy, as an electric motor operates, it also generates a current, but of the opposite polarity. The slower the motor spins, the less counter-EMF it generates; therefore, the motor draws more current. As the motor spins faster, more counter-EMF is generated, and the motor draws less current. A motor always draws the most current when it's powered but prevented from turning. That's just the way motors work, and it won't be engineered out in thirty years.

But it will not buy you another production car that can match the Tesla. In fact, a million dollars will not buy you a car that can match the Tesla.

Why the fuck would I want a Tesla? I can't afford one. You can't afford one.

You have no idea what you are talking about. The Tesla will most likely win a race to 100, but after that most sedans in that price range pull away from the Tesla.
Then, after half an hour at full speed. The ICE pulls into a gas station, refuels in five, and is on the road again.

Goodbye Mr. Tesla driver. Your ass just got smoked in real world driving conditions cause your sorry ass is still sitting on the charger.

It's usually referred to as inductive resistance. Most of the inductive resistance can be equaled out with capacitors though....but then you still have resistance which comes from increased wire length which can't be negated. It comes from heat loss. Those huge cooling fins/radiators are on transformers for a reason.

Batteries are a "stop gap" at best for EVs until some other sort of technology can be "discovered". Probably some sort of hydrogen fuel cell technology.

Only 40% of the population has a home that can even install a car charger in a garage increasing the urban sprawl at the same time. Apartments don't have such conveniences. A few new ones might...but even with the best technology today the batteries on an EV require 20 minutes for a 70-80% charge.
So...fuel cell technology is definitely the way things will eventually go.

Fuel cells can use petroleum products or ethanol (depending)

GM has the best fuel cell tech to date but it got squashed for a laundry list of reasons. None of which are really political. They developed it for lighter vehicles using JP8.

The world's supply of platinum though was the main issue. They did discover one using iron instead of platinum...but the cell had to be twice the size and still is susceptible to contaminants. (Which destroys the fuel cell)

So..progress..as always..being driven by consumer demand:

Electric vehicles close to âtipping pointâ of mass adoption

Sales increase 43% globally in 2020 as plunging battery costs mean the cars will soon be the cheapest vehicles to buy

www.theguardian.com

In a poll of electric car owners, 91% said they would not want to return to petrol.

Electric vehicles are close to the “tipping point” of rapid mass adoption thanks to the plummeting cost of batteries, experts say.
Global sales rose 43% in 2020, but even faster growth is anticipated when continuing falls in battery prices bring the price of electric cars dipping below that of equivalent petrol and diesel models, even without subsidies. The latest analyses forecast that to happen some time between 2023 and 2025.
The tipping point has already been passed in Norway, where tax breaks mean electric cars are cheaper. The market share of battery-powered cars soared to 54% in 2020 in the Nordic country, compared with less than 5% in most European nations.

Transport is a major source of carbon emissions and electric cars are vital in efforts to fight the climate crisis. But, while they are already cheaper to run, their higher purchase price is a barrier to mass uptake. The other key factor is “range anxiety”, but this week the first factory production began of batteries capable of giving a 200-mile charge in five minutes.

EVs are still less than 3% of the global market.

Hardly a "tipping point"
