Sometimes the KISS principal is the best. The solution is simple if not as efficient... the car should default to a traditional charging system when charge or ambient temperature drops below a given threshold.

Rodion, perhaps you have a point about heating the battery. The traditional location for the battery is under the hood (bonnet) where the engine heat may contribute to a better charging state. I wonder if other vehicles with trunk mounted batteries have this problem?
Yes, the E9X range. I believe the combination of IBS (which is irony at its highest) and efficient dynamics has a lot to answer for with regards to the battery issues or to put it better, perceived battery issues.

I now have a CTEK 7000 series charger for my garage which I use occaisonally.
