How quickly will capacity degrade charging at that speed?
If true then that's the real innovation for me. I don't want a car that I basically need to replace 70% the cost of every 4-5 years.
That's already not the case. Not only do you not need to replace the battery (the range is just slightly reduced over time), the degredation is a lot slower than that.
Yes reduced range is very important- especially when you live in a cold climate where range is already significantly reduced from that. The cold climate also speeds up the degradation of the battery.
Do you have experience? Adoption of EV vehicles in Norway is really high without much issue, and it's likely colder than wherever you live. Plus, 400km is a lot. The average commute in America is 66km. 400km might be used on a fairly long road trip, but if you can charge in 10m it's not really an issue. The everyday experience is just plug it in at home and it's done by morning. No gas station visits or anything else.
Most Norwegians also have much more disposable income than I. I wouldn't buy a new gas powered car either.
Sure. That's probably true but has nothing to do with the viability of EVs on a cold climate.
Nor does their market share in a cold climate where people can afford many more luxury goods- replaced more often.
They aren't just replacing them. That's a disingenuous argument. The fear mongering that EVs can't work in cold climates is just mostly made up. There are plenty of ways to handle it that saying they don't make sense is a horrible argument.
Current batteries can do 1000- 3000 cycles before the capacity drops below 80%.
With ranges of several hundred km this gives us hundreds of thousands km of lifetime mileage, if not a million.
Most ICE cars don't get that far either.
That's not really an honest comparison though, and also kind of simply doesn't matter.
Most vehicles will have some expensive component fail well before the engine, and after ~10 years almost any major replacement will cost $5k or more. My suspension gave out at year 8 and it would have cost me $5k to repair my Ford valued at $5k. Who's going to want to spend that - on an engine or otherwise - on a 15+ year old car unless it's a particularly well regarded model by enthusiasts? The average consumer doesn't care.
The average consumer wants a new car after a decade simply for new features (like sensors or safety), change of lifestyle (like going from a sedan to a van for kids or an SUV to a sports car), or even simply styling and aesthetic. If the battery lasts 5+ years than the average consumer wants the car in the first place, it won't matter.
Not to mention that in the coming years, the price of replacing battery packs will likely drop, while the price of replacing engines may likely increase, as OEMs ramp down engine production and ramp up battery production.
This is probably the biggest reason why I won't buy a battery powered vehicle right now, and when I try explaining that to people they're like "well then just lease or sell it and buy a new one lol".
It may have changed in recent years but several years ago when I was more into EVs it was a reasonable concern. But I do somewhat question the legitimacy of this seeing as how quickly small electronics Lithium batteries degrade.
There are now soooo many studies out showing that capacity in EVs drops significantly slower than ever expected. An EV that is used "normal" is basically best-case for Li-Ion batteries. You are charging the car once to twice a week and then you are charging it slowly over night or at your office, only using fast-charging when you are on roadtrips. You rarely drop your battery percentage below 30% and a lot of cars also dont go higher than 90% capacity without you explicitly activating it
Can you please send a source for the studies?
Do you mean phone batteries? Cause they are often cycled at least once a day. If you drive your ev for 500km a day, yes, don't expect it to last five years. But I would think an ICE car would handle that either.
Electronics batteries degrade within a couple years even with very few cycles in my experience.
