vs
Battery Tesla or OEM BMW
If I could easily repurpose the cells in my 140k mile Model 3 into home storage for my solar I would rather do that than sell the car. 3% degradation the car itself needed more work than a replacement battery ever would have cost.
Pros: minor battery degradation
Cons: car needed more work
Mileage: 140000 km
I’ve had my iX for 2.5 years and have logged 122k miles. I haven’t noticed any degradation in battery capacity. Just the normal summer/winter fluctuations (live in Midwest).
Pros: no battery degradation
Vehicle:
BMW
Mileage: 196339 km
I had one with the battery that lasted just under 12 years.... Old original BMW batteries are built different! Especially if the car is driven regularly.
Pros: lasted 12 years, built different
Tesla on nmc battery drops around 10% after 8 or 10 years (can't remember exactly) from what I read. But lfp battery is inherently able to have longer life span and charge cycles. On top of inherently having ability to be safer / less explodey.
Pros: longer life span, safer
Cons: 10% drop after years
For context, I have a first generation Tesla Model S - 2014. It has 215,000-ish miles on it. The battery capacity has gone down by about 10-12%. It still runs and drives like a dream. It's on the original battery.
Pros: runs and drives great
Cons: battery capacity decreased
Mileage: 346000 km
I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.
Pros: love driving it
I have an early VIN 2020 MYP with 80,000 km; the diagnostic says 87%, so 13% drop in battery health. Range calculation at 100% SOC dropped 4.9%.
Pros: diagnostic says 87%
Cons: 13% drop in health
Mileage: 80000 km
I don't want someone else's crusty ass battery. Charge times are already low and are plentiful (Tesla at least), I don't see the utility of swapping the battery out when I could stop for like 15 mins.
Pros: charge times are low
Cons: unnecessary complication
Vehicle:
Porsche
2019 model 3 SR with 10% loss based on full charge at 52k miles.
Pros: full charge
Cons: 10% loss
Mileage: 52000 km
530e with a little over 20,000 miles shows 10 miles electric range on a nice summer day. It used to show 15 when new. BMW said that the drop was not warranty worthy.
Cons: reduced electric range, not warranty worthy
Vehicle:
BMW
Mileage: 32187 km
