Battery degradation, how actually is it calculated?

RiotLabs 1 year ago updated by James 1 year ago 1

This graph is very useful to me.

However, as an electrical engineer, I would be very happy to know how the calculation is processed.

For instance, if I drive using lot of heating / air conditioning, defrost, seat heaters, of course I will consume more energy than when all theses are off.

So, the battery will drain more or less quickly, while same distance has been accomplished.

It doesn't mean the battery is degraded.

So I guess the calculation is based on more specific data that Teslafi can exploit from what you gather from official Tesla data base.

Could you explain this for those who like technical details?

Thank you very much in advance!

The battery degradation report is simply a graph of how much Rated/Ideal Range the vehicle is reporting at 100% or extrapolated to 100% full charge.

So the degradation would be 1.7%(5 Miles) if the vehicle reported a 300 mile range in October and a 295 mile range in December at a 100% full charge.

Hopefully that answers your question.
