Reply to comment by Brusion in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg

I literally work with a solar company that does EXACTLY what I described in repurposing EV batteries into home solar installs. You are the only brainwashed person here and you have zero idea how batteries work. All batteries have a life cycle, every last one. Batteries are also among the most reused, repurposed and recycled manufactured products in existence today.

The batteries in an EV will only outlast the vehicle if parts stop being made for that vehicle or the EV has so many issues that it costs more to repair than replace. The single most expensive part of an EV is the batteries, as long as the battery is safe and the repairs are not more expensive than replacing the vehicle, they will make the vehicle into an EV of Theseus because it's cheaper than replacing the battery. It's not uncommon to reclaim these batteries from EVs that were totaled in accidents.

Not a word of that changes the fact that ALL batteries have a limited amount of charge cycles before they need to be replaced, rebuilt or recycled. ALL BATTERIES. Every single last one. In fact every single time a battery goes through a charge cycle it holds slightly less of a charge. This is true for your Amazon rechargeable AA batteries just as much as it's true for EVs. It's simply the nature of the technology.

Again, you're still wrong. Yes, they get repurposed after vehicle life ends, but that has nothing to do with this discussion. Batteries are not dying before vehicles rust out and head to the dump. You can downvote all you want, but it doesn't make you right

It's like you didn't even read what I said because it addresses exactly everything in this reply

Yep, I did. And perhaps you missed the first post of this thread. If a vehicle is totaled, then the battery lasted the lifetime of the vehicle. I understand all the simplistic points you made, but the batteries do no go through there usable life cycle in the lifetime of the vehicle. Not a single person I know has had to replace a battery in their vehicle, no have we. You addressed nothing, and are simply going off on a tangent to start an argument.
