Hi Tuevo!

As you have a new Battery already, then we can rule that out.

In the winter, do you spend any time in the car with the heated seats  and heated rear screen turned on, before you set off?

If you are turning these accessories on with the 'System' not fully on in 'ready' mode (i.e. ready to select 'drive' and set off), then it will be the 12v Battery that is powering them, with no charging from the 'high voltage' Battery etc. at this point.  This could mean that the 12v battery discharges a larger amount than the car has time to recharge it, especially if your journeys are a short distance.  Perhaps you knew this already!

Have you had the car long?

Are you driving lots of short journeys? 

I'm guessing that you are in Finland, perhaps? 

How cold is winter where you live?
