This is my experience, my entire commute is flat enough to where the only regen that is useful is at stop signs and stop lights, I don't have enough stop signs and stop lights in my commute to recover the amount of power I use with my headlights on the way to work. Outside of the 4 month period of the summer where it is light out when I am leaving to drive home from work in the morning, 100% of my regen opportunities are put towards recovering the DC-DC load and I was pretty much always at 18 or 19 bars this winter/spring.
I have only once had the fan come on, that was when I deliberately cycled the battery down with assist and all the way back up again within the same trip. It charged up faster than I thought it would, the difference between 5 bars and 10 is about the same time in regen as it is 18 to 20 for me.
I won't know whether or not I need the fan while grid charging but if I don't have it, you bet there will be some form of temperature disconnect worked in there but I think I'd rather just run the fan as it is much easier to do and won't cost me pack life if I make a mistake somewhere else and induce some overcharging.
