Battery Power consumption

Hello together, I would be interested in the power consumption of the Kia Ceed SW Phev times. I charge mine on a wallbox and unfortunately have no extra counter. If the battery is on 0km (20%) and is charged, how much kWh does it pull then? Oh and by the way a small question. Mine is now 7 days old and has already a small stone blow on the bonnet (photo) . How would you treat it?
