New internal combustion car sales to be banned in UK in 15 years

Transporters like Star Trek? Ok, back to reality.

We already know they are the car of the future. They already are at the current battery levels. It'll only get better.

It is reality. They've already transported tiny molecules. It's a start. And who knows what will be invented tomorrow.



And if it works on your motorcycle that's great. Can that translate to larger batteries for cars? And does that hurt the life of the battery? Once they get the kinks out of electric vehicles they will have a lot of good applications.

I'm aware of what you are talking about, and no, they did NOT teleport tiny molecules.

Yes, large batteries work the same, and their size doesn't matter much because they are collections of small batteries, but in general, what you are proposing that you are saying is a problem, is not a problem that exists.

Companies like Toyota are spending billions on the next generation of batteries. I can only imagine how much cash VW is stuffing into it. If they get zero out of that money in 5 years how long are they going to keep spending? Supposedly Toyota says what they are working on will be able to charge extremely quickly, like 15 minutes or so. If that comes to pass then range anxiety will cease to be a thing. Toyota has mentioned as early as 2021 as a date they are aiming for to produce these solid state batteries for cars. If they even miss that by a year or two it will still totally change everything and these mandates will seem silly. The other important part is weight. If they can figure out how to make them weigh less that can also change the range. Technology can advance rapidly when companies spend this much money to change things. Governments only screw things up.



The UK isn't the USA. You don't need any vehicle in the UK, so the people that do have them use them differently. They can sit for weeks doing nothing. Do we even know if that is going to cause any issues? Are people going to have to worry if these batteries sit for a month or more? What about if they are used only once a week to go get groceries or run errands? Will the batteries wear down faster in that type of use case?

Depends on the chemistry. A lot of current batteries that are used as starting batteries like the Shori are Lithium Iron Phosphate. As long as the don't drop below the the BMS's low voltage protection range they are okay. If they are going to be stored for an extended period of time they should be discharged to a storage capacity to maintain good charge capacity over their lifespan.

That being said, a lot of EV batteries are not LiFePo. I can't really speak on those as I do not have experience with them.

You don't have to. I already posted a link with the information.

NMC isn't on there.

Combustion and explosion are very different occurrences. Put an explosive in a combustion chamber and very bad things happen.

Why are you comparing a country the size of the US to a country that is almost the same size as New Zealand?

Is this not an international forum about discussing car stuff anywhere on this planet?
My wife drives a boringly reliable reliably boring AU camry.
Is this not similar to a US camry?

Yes. For the sake of my point engine combustion results in rapidly expanding gasses, extreme sudden pressure and heat. Would you feel more comfortable with "creates forces equivalent to an explosion"?

No, because it is still an incorrect statement. Explosions in, say air-filled chambers, have very different pressure profiles than combustions. It's not a question of magnitude, it's simply different. That's why detonation (knock) is very bad for ICEs, where it can perform combustion totalling that same amount of energy pretty much all day every day.

Well the end result is far greater stressors on and ICE than an electric motor which is the message at hand.

That's also not really true... Electric motors have to deal with the same amount of energy, or more if you consider EVs weigh as much as a small moon. They just have less contact surfaces to wear out and less parts overall.

Far far less parts. No valving, lifting, camming, oiling, liquid cooling, charging, exhausting, vacuuming, fueling (well sort of fueling), all of which can break.

No reciprocating forces either.

Do we NEED to get rid of ICE cars? Or will reducing them to a certain number suffice? I imagine it’s the latter.
