Battery health test

just mentioning this as we have folks from multiple countries commenting here, which probably use different rating systems and may have slightly different ranges as a result.

no, regardless of the country, the range displayed at the top is always the EPA rated range.

444km’s, when new I could get 460km…..of course Tesla said 560km’s (rated) but real world was 460km’s, now just under 5 years later it is 444km at 100%

Confusing due to vehicle type uncertainty (probably is a 2020 from late 2019). I guess you’ll have to use the energy screen method to see your capacity loss. You started with 77.8kWh or so.

I’m going to guess you’re at 71.8kWh with 7.8% loss.

Seems about right.

In the end since we know what the initial capacity was all you need to know is current capacity.

I just sold my 2019 Model 3 performance (July build), it was last showing 446km range, Scan My Tesla was showing 69.4kWh

I can’t get those numbers to quite work out.
446km at 100% for a 2019 Performance should be 446km*152.2Wh/km = 67.9kWh. (Which is a bit on the low side, so I suspect it is not that and I believe the SMT number, but depends on vehicle use.)

But, it’s not too far off. I would have expected 456km at 100%.

(I suspect the other vehicle being discussed here has a 2020 161.7Wh/km constant. We’d just need an energy screen picture in km display mode to know.)

Screen capture of your final data would help I guess.

I sold the car unfortunately and I removed it from Tessie so I can't see the history anymore.

Actually found tessie garage feature. Range was 454km

So you're saying that in China, cars built in China display the US EPA rated range? I somehow doubt that.

Not sure about China itself as I've never checked the car.
But everywhere else? Yes definitely.

That includes European countries and Australie which don't otherwise use the EPA range.
