Tesla batteries fail after 8 years at least from models up to 2014
- stetrain 1y agoThe number of Teslas sold up to 2014 is less than 1% of all Teslas sold. Tesla has an 8-year battery and drivetrain warranty but they don't necessarily fail after that date.
- p0w3n3d 1y agothere is an ubiquitous failure of Panasonic-created cells for Tesla. I made a research on forums, because I wanted one, and investigated why there is such a price drop. Cars getting close to the age of 8 years immediately drop on price to even 10k usd. It's because if you get your battery replaced on warranty - you won. Otherwise it often deteriorates suddenly.
- stetrain 1y agoIt’s understandable that people would avoid out of warrant EVs, we don’t have that many years of data on old EVs yet. Anecdotal forum posts are not a great source of statistical data.
- trhway 1y agoPrius Plugin 2015 (last year of that model) - full charge/discharge at least 3-4 times a week, currently still a bit more than 80% of capacity (granted the battery seems somewhat overbuilt, yet it is normally does 10-15C which is much tougher mode than in a pure EV where 2-3C is usually enough and only high-end Teslas and the likes would do 5-6C). There has been large continuous improvement in lithium batteries over the last couple decades.
- nandomrumber 1y agoWhat does any of this mean? What is c in this context?
- trhway 1y ago1 C current fully discharges battery in 1 hour. Thus 4KWh battery running 60 KW engine means 15C current, and it would discharge the battery in 4 minutes (in a very simplified linear model).
- dtgriscom 1y agoFrom my model airplane experience, I believe it's "capacity per hour". So, a 1Ah battery discharged at 1c would mean 1 amp; discharged at 10c would be 10 amps. The higher the C, the harder the batteries are being used.
