“Not sure on tesla batteries, but I know older Prius batteries were good for about 200k or 10 years.”
Prius is a hybrid, not an EV.
Tesla has been testing a battery that shows so little capacity loss that they are saying it could be a 100 year, one million mile battery.
Tesla real world data shows that their batteries installed years ago are good for 20+ years and several hundred thousand miles.
I am aware of the difference between the Prius and the Tesla.
I only mentioned the Prius battery as That was a Battery data point I am familiar with. It is significantly smaller and used less. to me, a larger Tesla battery would have less of a lifespan.
Thanks to your info, I see I was wrong.
My only question is how exactly is Tesla testing that battery.
Lab tests will always outperform “real Life” statistics. Still, I figure the battery would need to last for 200-300k to well outlive the average lifespan of most Vehicles. so the lab test, even if its grossly over estimated, will still surpass the 300k mark.
This means that using teslas as Grid batteries would be feasible and not negatively impact the Performance of the battery, which is good. Decentralizing the grid is a good thing, even if its just a small thing like this.
