The latest battery chemistries perform incredibly well in cold and hot climates.

Internal combustion is not clean, and is inherently significantly less efficient than an electric motor.

Also, LFP chemistries are incredibly safe compared to NMC, which is what you're concerned about in terms of thermal runaway.

ICE is mostly stagnant tech. Meanwhile EV tech is rapidly improving!

Oh? Show me a model of EV that has it is going to lower capacity battery heating and cooling systems.

I’m an automotive EE… I can’t name any. I’m working on things that will go in 2032 vehicles. Surprise, most are ICE, but of the EV vehicles the battery protection systems are becoming more rugged, not less.

Where does your supposition come from?

Sodium batteries loose only 10% or capacity and doesn't need pre-heating when charging. Latest Chinese LFPs perform well in cold too (I don't know exact deets and tbf they don't do great job publishing them other than marketing fluff). Also added ripple preheating that Tesla has.
I'm surprised they didn't flag and downvote you. There seems to be a certain crowd that seems view EV as sort of a panacea without considering the true realities which involve experience and research to know they are far from replacing ICE
If ICE is the only vehicle for you, because of religious reasons, thats okay. There are large and small countries ( China, Norway) that have majority EV cars and continue to grow. There are 120+ other countries that are buying EVs. Even in US, there are a few people who have bought EVs and realized it works for them.

A person who really needs an ICE car would encourage others to buy EVs because it would reduce oil demand, and with demand destruction, considerably lower oil prices. With lowered demand, Saudi Arabia can supply a barrel for $5 - $10/barrel from Ghawar Field. Which means a gas-head who commutes every day from Yukon, Canada to Guadalajara, Mexico has a significantly lower gas bill.

The only people who wants everyone to buy ICE are fossil fuel shills.

I find this whole discussion weird.

The whole world is in a transition phase. For some it will make sense to jump to pure EV use, for others it won't. That whole “The future is already here – it's just not evenly distributed.” thing...

I have one of each. They work well for different reasons.

EV is the charge-at-home city car that is preferred for every day use.

The ICE is for when two cars are needed and long distance travel because charging stations here are not well sorted yet.

My plan for the future: The ICE car will be replaced with a hybrid with a significant emphasis on battery. Then eventually it'll be an EV as well. We'll get there.

Thats right, most families with 2 cars can immediately switch to an EV and use it as a daily driver.
This is the correct use for EV. A second car, around town. Perfect.

The EV push back is because the MBAs decide to market them as replacement daily drivers. And despite the people that went all in being part of the same reality that has caused the massive pushback against EVs… they will defend their purchases to the death.

I have had two EVs for around town. Love em. But not real for only car outside of California.

> If ICE is the only vehicle for you, because of religious reasons, thats okay

so you admit EV is a cult if ICE is a religion ? that's not okay.

I finally met someone who plans to downgrade from EV to ICE. He does 100k km per year, running multiple businesses. Lives 120km outside Dublin. Biggest issue seems to be wait at public charge stations. IMO he needs to get long range EV and get better chargers at home/work. But oh well, I'm not going to stop him if he's going to get luxury sports cars instead lol.
> Biggest issue seems to be wait at public charge stations.

No one has ever said “man, I love this gas station and wish I could stay here for two hours”

… idk, I guess people like Buckeys for some reason.

TBF Most of my stops aren’t enough to have quick meal with kids, let alone proper dinner.

If you live your life in a hurry it can def be a problem.

Depends on your definition of cold. California cold sure. Wisconsin cold you are looking at losing 40%-60% range.

China cold tests their EVs in Harbin and Mohe, where “cold” means -40 (F or C doesn’t matter, it’s the same). They lose some range, and indoor charging garages are more common (for better charging performance), but the tech has gotten good enough that even harbiners (a small city of 20 million people) are adopting EVs at a rapid clip.
so good that batteries are ejected when they catch fire
It is so rare for EVs to catch fire that it makes the news whenever one does, and these form the core of the anti-EV memes that are popular with boomers on Facebook.
never seen an ICE catch fire on its own

but its rare you say ?

I’ve seen plenty ICEs catch fire on the side of the freeway, no idea how they got there but it’s not “news” when it happens since it happens so often.
