At 9.5 years in to owning this EV, the stats are interesting. It has lost about 10% of the battery capacity from new having completed almost 135k miles (217k kilometres).
The weird jump up in the graph is due to the car originally coming with a software limited battery capacity that was later removed, giving it a sudden upward jump. The graph shows that battery capacity is estimated as it has increased over the past 10k miles.
