Nio is a Chinese auto maker that offers an alternative to charging: just swapping out the whole battery whenever you need it. I borrowed one of their cars. ■...
You have that backwards. The vehicle is good for the life of the battery. We could design EV where the shell and motor last 30 years, and the battery just swaps out every decade or so.
Cars get in accidents all the time, many of which will total it. Over time, the probability of that reaches 1.0. Most cars will not make it to 30 years regardless of how well they’re made.
Yeah and that’s why I’m not advocating for 100 year cars.
I’d be pretty happy with 20 years to, but 10 just feels like planned obsolescence.
I also messed around with the math very loosly, and only accounting for crashes that total a car, they could be expected to go 20 years or more on average.
And that’s now with all the terrible driving that happens, especially at night.
With slight deacrease in accident frequncy that number can increase a lot.
So maybe 30 is a bit much for now, but I’d still like an ev that would claim to last 20 yeara.
Making cars repairable and making the parts swappable will extend other cars lives, especially if they standardize around certain parts like batteries.
I don’t think so. Think of the engineering challenges. The battery would have to be a separate structure so more weight, less range/performance, more wear on tires and brakes, less rigidity unless you add even more weight, etc.
Batteries can be replaced now. It’s just a time consuming job but one that might only need doing once.

Very few cars now last 30 years. The US average is 12.5, which is about how long EV batteries are expected to last.
But you still have it backwards.
We could very easily design and build a car that lasts 30 years. But we don’t, because manufacturers don’t want them to last that long.
Evs don’t have transmissions, or complicated engines, and the wear on brakes is much less with regenerative braking.
Other things like air conditioning and interior coverings could be easily servicable
Why should the life of an ev by limited by its battery?

Either way, you’re complaining that EVs don’t do something that ICE cars also don’t do.
The average car age is 12.5 years, so many of them are likely approaching 20
