20.3% Tesla Battery Degradation

Our Tesla Model Y rarely sit for a day without driving and often 100+ miles since the site we stay at is far away from grocery shopping and anything else :-). I have been watching the Bjorn Nyland channel for years and was inspired by all his EV testing to buy the Tesla Model Y. We have now driven 116,821 miles (188,004 kilometers) in the car and love it.

We live in an RV and can charge at home from solar, we have done that 11950 kWh, because we road trip extensively has the car been charged 30545 kWh on DC Fast Chargers, mainly Tesla Super Chargers. With all the miles driven is the AC home charging over 11,000 miles per year that is pretty common for a normal car use. All the DC Fast Charging has come on road trips.

We have recorded all the DC Fast Charging stops in a Google Map. The actual map with date and descriptions can be accessed here DC Charging Map

The ScanMyTesla app report internal data from the Tesla car including the estimated battery capacity (needed by the car to do precise routing). That is where the current battery capacity is shown as 65.4 kWh. The App also show the capacity at new 82.1 kWh . This is a Tesla Model Y Long Range with the Panasonic Cells.

 

With 65.4 kWh remaining capacity of 82.1 kWh is the degradation 20.3%. That only leave us with a 79.7% remaining capacity or 263 Miles (423 Kilometers) range compared to the originally rated 330 Miles.
