miscalculation of kwh during charging

[crevasse]

Hi my zs battery capacity is 72,6kwh, I am aware that the car keeps some capacity for emergency and I can use 65-66 kwh. I always charge to %80 which makes around 55 kwh capacity.
Yesterday when my battery is %2, after drivlng 350 kms. I charged my car and expecting at least 50 kwh spending but with only 39,5 kwh charging session ended and my car is %80 charged. I really can’t do the math of battery capacity. Any ideas…

Might have to clarify your question.

You were expecting 50kwh at 80% state of charge?

Are you saying the charger delivered 39.5kwh in one session where the car went from 2% to 80%?

Yes that’s exactly what happened

There will be some charging losses. 10kwh is fairly large though…

I would question that the charger delivered that figure you state.

It’s a pulsar plus wallbox. I agree, the charger app doesn’t show the correct kwh usage. Will check this out. Many thanks

When was the last time you charged to 100%? The battery needs a full charge every now and then to recalibrate the displayed capacity and balance the cells.

Charged to %100 the day before so the recalibration should took place.
