Continuing last year’s post, here are my results from 2 years of almost exclusively using superchargers to charge my Model S.
A snippet of my battery degradation after 2 years, data from TeslaFi.
Today marks 2 years of owning my Model S. I will cover all the maintenance, repairs, and battery degradation reports since last year.
We’ll start with the most interesting data. Here’s a graph from TeslaFi showing the estimated battery range at 100%. This includes all charges over the last year with an ending point of 60% or greater.
When new, the car should report 270 miles of available range. When I first purchased the car, my starting range was around 252.5 miles at full, with 92,700 miles on the odometer. In the two years since, the range has followed a pretty steady trend downward, as is to be expected. It currently sits at 239.92 miles when full, representing a roughly 40-mile range loss over the ~128k miles it has traveled.
The range has decreased roughly ~12.5 miles since I got it, while I have put 32,500 miles on it. This amounts to a loss of 1 mile of range about every 2500 miles driven.
Since last year, I have driven the car 14,830 miles, and the battery has lost 7.5 miles of range. This shows increased degradation of roughly a mile of range loss every ~2k miles driven. We started seeing much higher degradation around the 120k mark.
I have now supercharged 442 times at 107 different supercharging locations totaling 13,773 hWh taking a total of 12 days and 1 hours with an average charge time of 40 mins.
Everywhere I have charged in 2 years of ownership.
I visited 21 new superchargers in 2024, though many of these were just new locations that opened up near me.
My biggest maintenance cost was replacing the high-voltage battery fuse. This cost me $323.56.
Other than that my entire cost breakdown is as follows:
I had a failure of my MCU as well but this was replaced out of warranty for free on goodwill by my local service center.
