HYBRID Q: Does pre-entry cimate control also heat up battery (to get better range)?
I'm not talking about pre-heating the car so it won't have to use the battery.
I mean, wil it also heat up the battery to get better range?
In the summer i get abt 52 km out of the battery (my work drive is 50), but in the winter it's abt 45/47
Info i find on the web is vague and/or limited
EDIT: i found this, but it talks about full electric cars. not sure if the same goes for hybrid ?:

Winter in Marseilles? I don't think there is any winter even in the Netherlands, perhaps just a bit colder weather. 
The WIS function descriptions are a bit vague on the topic but I don't think the hybrid has any high voltage battery heating at any point, just cooling if needed. Full AC-charging power can be reached at pretty cold temperatures anyway. Perhaps DC-charging would need battery heating but at 60 kW DC charging my 223 charging power is still a bit less relative to that of the EQS maximum charging power. In any case, hybrids have the ICE if the electric power train cannot provide the necessary power.
The fully charged battery would still have the capacity even at cold temperature, it just may not be able to provide the full power (current) if the battery cells are cold. During normal driving in electric mode, the battery would heat up and towards the end of your trip, the battery would have provided the same kWh energy as at summer time. The relatively small range change that you have observed must be coming from the need to heat up the cabin. If you would face real winter temperatures (minus Celsius, down to -20 or even less), you would observe a huge range reduction even if you started the trip from a heated garage (normal battery temperature).

Thanks,
But this would mean heating the car costs more energy, then cooling?
It doesn't get very cold here this is true, but anything at 10/12c is quite normal in winter,
whereas in summer it's over 30c. does that really not affect the batteries performance?

Yes, heating consumes a lot more battery than cooling. Hybrids do not have a heat pump for heating like EV models do (at least in cold regions). Air conditioning has the efficiency of a heat pump.
