MINI Countryman PHEV cold issues

During the last few days when it has been below freezing, my car will not run in full electric mode.
When I press start (with a fully charged battery) the ICE fires up this is despite having climatised the car whilst plugged in. The gauge on the dash shows zero miles available and there is a message saying battery power temporarily unavailable!
After a few miles running on ICE, the battery warms sufficiently for the car to run in EV mode.
As an example yesterday it was -4C, so I climatised the car. The app showed only 14 miles available but was at 100%. The car would not run in EV mode, so was running on ICE. After around 6 miles or so EV mode became available, but the range was only showing at 6 miles! I continued my shopping trip but after 14 miles the EV mode was no longer available, so my journey was finished on ICE.
So a 16 mile trip, the first 6 and the last couple on petrol, means only 8 in EV mode!
Strangely despite the app showing 14 miles before I left home, it took 6 miles on petrol before EV. mode was available and then the range was showing as 6 miles. How did I loose 8 miles whilst travelling on petrol?
Incidentally the charging port would not latch shut when I unplugged the car, I had to dowse it with de iced, and cycle the door locks a few times before the latch would secure the port door.

If this is all down to the battery being cold, how does this car operate in Scandinavian winters?

I wonder if BMW have implemented something in software to stop running off the battery in sub zero temps? There is a big power drain heating a car from the electric heater, and if you used that before switching to the ICE you probably wouldn’t see much electric range.

I’m sure some owners will chime in, but the fact you’re getting a message saying it’s unavailable until the car is up to temp suggests it’s by design rather than a fault?

The Golf GTE PHEV I had would always use whatever power source I asked it to, whatever the temp, but it did always default to starting in EV mode anyway.

Hi - I have had my SE for 3 years now and I had this for the time this winter when temperatures were very low - I wonder if my car enabled this at the last service when they did routine software updates?

The first time this happened a few weeks ago, like you, I lost around 8 miles of range. On two other occasions, I was running on petrol for only about a mile before I could use electric and had 14 miles of range available.

My car is due a service later this month - I will ask about it then.

I think that the Mini is a very different type of PHEV to the Golf GTE and that it's designed to keep its (very) limited electric range for very particular circumstances in the cold. The GTE has greater EV range and more control is available for the driver.
With a very limited EV range it makes sense to retain it for driving rather than interior heating which is more efficiently provided from the waste heat from the ICE. Also, the Mini has its 4WD trick which is only available with EV power so reserving the battery range for that makes sense in "extreme" cold.
But none of the above justifies why the EV range is so low. I wonder if Mini are increasing the battery buffers to protect it?
