I hear the market for fire fighters is going to be booming.
These brave guys are rushing into a possible timebomb much different from a conventional fuel fire. Our local fire dept. doesn't try to 'extinguish' hot burning EV/energy bank battery fires unless there is a life or death emergency. They use suppression to contain the damage to the vehicle/storage space and/or local environment. Their SOP is to wait and let a car burn down to slag while using traditional suppression and extinguishing of secondary fires from it.

The position of the battery makes conventional cooling the fire hard. You just don't have access to put a cooling water stream inside the energy cells, almost armored enclosure, because the battery is likely a structural element of the car unlike a regular gas tank.

IP rated and waterproof until it explodes or is breached in an accident.

The only saving grace is that EV fires are still rare compared to most fire calls. When it does happen, those guy can be in a world of hurt in a instant.

So. Ev battery cost more to replace than car . Yes , I've had my two EVs 8 and 10 years, and the second hand value is about the same as a new battery , but
Both cars still get ,250 to 300 miles on a charge , charge up in around 45 mins , or overnight at home on the lower rate electricity .

No distance ? What distance do you need ?

Must admit , on my recent drive around California for a month , ev chargers were very hard to find , but over hear in Europe , it's a very different story.

Law enforcement and EV is to control the nation ?
Well , the fastest acceleration cars now are ev,
They have been banned in drag racing here as they were winning everything .

A V8 engine is more environmentally friendly than an EV ?
I just don't know what reliable source your using !
The batteries now in Europe are being recycled , 99 Percent is re used..
Yes the plastic of all cars , be that has or ev is a pain to recycle , but that's not an EV distinction.
All the electrics in the EV are re cycled , it's copper and steel ,
Look at the gas engine
The gas itself is polouting
All the oil and stuff the car needs also
An ev is just a simple sealed electric motor . No gears, no complications .
The power for EVs is sent over standard power lines. These are none poluting , very long life and can be recycled .
Compare that to all the trucks moving gas around , chucking out black soot , and the gas that evaporates on route , also adding to pollution.
Evs can use any electricity source , make it as green as you want .

As to why you go on a vendetta and name calling , I do not know .

So do i take it that you don't believe pollution is causing an atmospheric problem ?

That's another question.

But please post these references to ev are not as environmentally friendly as a V8
In this state of NJ there is now a surcharge if you own and EV. When you renew your registration, you have to pay an additional $250 USD, in 2024. Now it's 2025, so you have to pay $260, then next year $270, and then the next year $280, and it is 'supposed' to end there (the increases, not the surcharge) but we all know how that works out. A regular registration costs around $65 without that surcharge.

Is the surcharge a 'replacement' road tax for the loss of gas taxes?

They want to do per mile charges for EVs here.
Oregon looks to expand per-mile charges for electric cars as gas tax sputters

Oregon recently celebrated registering more than 100,000 electric vehicles, which Gov. Tina Kotek called a “milestone” for reaching the state’s climate goals.

But that milestone can also be a millstone around the neck of the state’s transportation system as lawmakers try to figure out how to produce an estimated $1.8 billion annually for the state’s transportation needs. Sputtering revenue from the state’s 40-cents-per-gallon gas tax as Oregonians drive more fuel-efficient cars — plus rising construction costs tied to inflation — contributed to that deficit.

Electric vehicles, which have made up about 5% of the cars registered in Oregon in the past decade, aren’t subject to the gas tax. They’re subject to higher title and registration fees than gas-powered cars, but the average driver of a gas-powered car still pays more in gas taxes than electric drivers pay in other fees.
That EV cheaper energy for X mile advantage is going to be a revenue source in the future. Even if you get the power for 'free' from residential solar, you still will pay some percentage of gas priced miles to drive on the roads. Those 'surcharges' likely will continue to jump up, yearly after year, until the fees have EV miles just as expensive as 'fuel' miles,

They will tax the sun.

Sounds like your legislators in nj don't want Elon musk to make more money.
There is no accounting for how politicians behave.

They don't care about Elon Musk making money, they just want a cut. It's shocking ,shocking that it's all about the Benjamins, not politics.

Hi,

If I understand it right, they seem to be worried about losing taxes on gasoline which helps to fix the roads. If the drivers don't buy gas, then the gov does not get that tax revenue and therefore cannot afford to fix the roads.

What I do not understand though is who the heck is doing the accounting for them, a baboon? Just like with air pollution, they are charging a flat rate when trip distances vary a lot. If they charge $250 for car A and for car B and car A drives 100 miles per day and car B drives 1 mile per day, then car A does more damage to roads than car B ever would. What if car B drives only 1 mile per week. Does not seem fair to charge car B the same as car A.
That's not how anything else is accounted for that I know of. If you rent a car you end up paying some fee per mile, so a person that drives 1000 miles does not pay the same as a person that drives 10 miles, no way.
I talked to someone that was inside the Motor Vehicle Agency related to automobile emissions, and they said that, "Then the person who drives farther would think they are getting a raw deal". Well duh, yeah, that's how things work all over. You use something more often, you pay more. Should everyone in the USA pay $250 per year for milk?
In his defense, it was an off-the-top-of-his-head reply he had little time to think it through, so I don't really blame him. All this stuff needs to be thought out more carefully.

The battery gauge reset and 100% charge is very important for LFP batteries. I use LFP for my solar energy bank and the energy routines I designed for tracking energy IN/OUT are very good but the drift with LPF partial recharges is about 1% per day if you bring the back down to say 40% and recharge to 80%. I normally recalculate actual battery energy once a month with a 100% charge (battery HI shutoff from charging) and down to 0% (BMS shutoff due to low voltage) to recalculate the energy computer NVM coefficients and total 'real' battery energy offset.

Why should they be surprised by a bogus comparison?

They seem to comparing old Tesla NMC to newer LFP. The data looks ok in the paper from a quick read as a chemistry comparison but it's useless as a comparison of new Tesla LFP cells to BYD LFP cells.

Move along, nothing to see here. There's a reason the engineering building is separate at most schools. My girl was in the science building that day. She said it's not the first time the ENG building was evacuated due to a student project gone nuclear.
