JAC Motors, a Volkswagen-backed Chinese automaker, unveiled the first mass-produced EV with a sodium-ion battery through its new Yiwei brand. Although sodium-ion battery tech has a lower density than lithium-ion, its lower costs, simpler and more abundant supplies and superior cold-weather performance could help accelerate mass EV adoption.
You know, putting and removing batteries would be a very tedious task and I really doubt that many owners will bother with it.
It wouldn’t be necessary very often unless you’d want to take advantage of swapping instead of reloading.
also it’s not a trivial task to engineer for swapable EV batteries, doing so comes with a whole host of disadvantages / compromises that don’t make sense for most (I guess) consumers right now. It’s not very different from the phone battery issue, except on a huge scale and with much more severe consequences if things go wrong
I mean, US Cellular had a free battery swap program for a while. If you were a subscriber and your phone battery was low, you could go into any store and they’d swap you out for a fully charged battery for free. I presume they just ate the cost of damaged or degraded batteries as part of it. I only used it a couple times, but it was kinda nice.
