75D Battery Percentage inaccurate? (FW: 2017.42.1 94435ee)

[ChooseAnother]

Hi all,

I just got my new 2017 S 75D.

Lastly, i charged to %85 and then consumed to %42-43. Consumption was %42-43 too, obviously. But "Since Last Charge" meter was showing only 25kwh consumed. How it possible that %42 percantage usage rated as 25kwh? 75's usabe battery capacity is 72kwh. Even %50 of it should be around 36kwh and %42 should be around 30kwh. Looks like there is a huge inaccuration on my percentage(like 5kwh)? Any ideas?

Thanks.

PS: I just charged to %100 and recalibrated the battery.

I’ve always found the percentage meter to have some wild fluctuations. I drive the same trip every day, and per the trip meter use almost exactly the same kWh every time, and the battery percentage can be 5-7% different from trip to trip.

I think that wasnt like this in older firmwares, weird...

Update:

Today, i just charged my S 75D to %100 and started to drive. I drove 240km and used 59,3kwh for this ride. And my final remaining battery percantage was %5. This is weird. My battery is 75kwh and usable 72,5kwh. %95 of 72kwh is not 59,3kwh as i used lastly? Why is remaining battery percantage shows wrong datas?

Total energy in that reading doesn’t include environmental controls, accessories, or include vampire drain.

I think it includes. You can see how much HVAC system consumes while on driving 0km/h And i think it adds on Total Energy.

Yes. It doesn't include consumption on P, nor heat loss due to internal resistance.

I didnt stay that much on P and heat loss due to IR shouldnt be that much like 10kwh inaccuracy?
