I've been experimenting with charge settings, initially charging at 90% since that is what Volvo started recommending back in July after first recommending 80% and for this reason:
Updates in software version 1.4
Preheating of the battery when charging to 90% and 100%, gives improved range. No preheating when charging under 90%.
So I normally have car always plugged in now and have charge in car set to 90% and normally use app to tell car to preheat about 30 mins before I plan on leaving and this works well with battery warmed up and car always nice and cozy warm and my initial battery use close to normal.
I've just spent the past week with temperatures here hovering around 5c-10c or mid 30's to mid 40'sF and tried to use charging to 80% to see if I could get same result even though Volvo 1.4 update said I couldn't.
I found that normally when I told app to preheat 30 mins before departure it would show heating sent to car and then I would see the red interior warming the car but within 1-3 mins this would stop and sometime I would goto car and check and sure enough heat was off. I've tried this a few times and found it was erratic, sometime I found the fan blowing but no heat and steering wheel heat not on also never noticed any preheating of battery. Also I found setting charge level to 80% gave me anywhere from 78% to 85% but 90% always gives me 90%.
So now I feel forced to keep car plugged in and charge set to 90% if I want a nice cozy car for departure just like update 1.4 mentions.
Anyone else playing with these numbers that have different results?
