Boy it sure is easy to win a debate when you use fictional information
I am being serious - can you factually counter those points? I'd like to know the truth of the matter.
I can. Electric car batteries last 10+ years, often longer than the body work of the car. Lookup Lithium Iron Phosphate, this has around 5-10x the cycle life of conventional lithium batteries. Combine this with the complex heating and cooling systems, battery and charging management in modern EVs and you have something that lasts as long or longer than even a diesel engine.
Cell phone batteries die quickly because both their construction and the way they are managed favour capacity, cost, and charging speed over longevity. Car battery design is much more focused on longevity by comparison. They are also cycled more often and more completely than most EVs.
Grid issues are a real problem. Cars can be used to make this worse or better depending on how they are deployed. If they are charged during peak energy production from solar they can actually help rather than hurt the grid.
You can also rapid charge a car in like 30 minutes. You don't need 12 hours.
Thanks, I'm not sure why I was downvoted for asking a legitimate question.
I suspect people just assumed you were the same person who wrote the sarcastic comment before the one you replied to and that you were just being combative
Well.
To fully charge a leaf at a public fast charging station takes an hour. https://www.nissanusa.com/experience-nissan/news-and-events/nissan-leaf-charging-101.html
My up! can get about 260 miles out of its 30ish liter tank. That is about 1/3rd more than a new leaf. Hardly half the distance.
The electric grid will be fine. This is not the first time it's expanded because of new technological demand. And I've never heard of 5 EVs overloading the grid.
And if the person above could read they'd see that all of these are battery problems, something the original comment said we should have put our focus improving on long ago.
Edit: I'll just add that I love my ICE cars as much as the next petrol head, but the future is electric cars for at least daily driving. We've pretty much perfected combustion engines at this point. F1 engines sit around 50% thermal efficiency, and we're not gonna get any meaningful amount above that (but I will be happy if it turns out I'll have to eat my hat in the future). I just hope petrol engines don't become banned in the future for the enthusiasts.
Batteries don’t fail after 5 years, for starters. Source: literally any used car site
15 minute recharge adds hundreds of miles of range

No, you see, that's not how it works. The battery needs to be filled to 100%, just like a gas tank. And you should only ever charge once you're under 10-20%, just like a gas tank (it's silly to top up every day, that's just a waste of time). We must be able to exactly replicate the current paradigm for people to be able to adjust.
I drive about 150 miles a week and get gas every couple of weeks. It takes 5 minutes. If I have to go to a charger I'll be there for hours. It's absurd.

When you look at fueleconomy.gov you will see that the furthest a compact ev can go is 149 miles while the furthest a ice compact car can go is 594 miles
https://www.cnbc.com/2023/07/01/why-the-ev-boom-could-put-a-major-strain-on-our-power-grid.html You can read cnbcs article on how the grid is already pretty spread thinn with us already increasing our power demand by almost 3,000% in the last decade without even considering ev charging
https://www.motortrend.com/features/how-long-does-it-take-to-charge-an-ev/
According to motor trend DC charging is the fastest way to charge your EV and it still takes just under two hours Couldn't find a source that studied how long a ice takes to recharge but considering how ices are currently extremely common you can easily test that yourself and probably already know it's so quick you don't even think about it
https://www.caranddriver.com/features/a31875141/electric-car-battery-life/
According to car and driver those lithium ion batteries you mentioned while yes they can last a decade most cars typically stay on the road for give or take 30-35 years and lithium ion batteries are inherently expensive and prone to thermal cascading ie catching fire also full charge and depletion wears the battery down over time
https://www.edmunds.com/electric-car/articles/electric-car-battery-replacement-costs.html According to Edmunds.com the average cost of ev battery replacement costs anywhere from 5,000$ to 15,000$ So what point was made up
You have all kinds of nonsense in your post. Like you limit it to just compact cars for no reason. When you don't limit it to just compact cars then you get EVs with 516 mile range

And charging a car for 15 minutes gives you hundreds of miles of range
