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.
Lithium batteries dont like being stored fully charged they will degrade over time.
This is a solved problem. Most EVs won’t let you charge it to the actual 100% level or discharge it to 0.
Exactly. Really, “fully charged” should just be conceptualised as being at a sensible safe point, with the acknowledgement that it’s possible to “overcharge” the batteries to an even higher level, chemically speaking, but that all sensible devices don’t let you do this.
So only charge it to 80% and pretend 80% is 100%, like iPhones do. Why is that a concern?
You’re right. Forgot about that. Shoot.
