> almost zero regen-braking

This is interesting. I wonder if large capacitors could alleviate this: somewhere to quickly dump the regen energy, and charge the battery with it at some slow rate equivalent to the long-term average regen load. Not only would it help in cold situations where the battery can't be charged quickly, but also situations where the battery would be healthier if not charged quickly, which is always.

While not giving any energy back, Teslas can now detect when regen breaking is limited, and blend in the regular brakes for you, so that you don't have to change your driving style. It has only come out in the past couple of weeks, but I cannot tell the difference when regen is supposedly limited after enabling the feature. Before it was a little dangerous to have to modify your driving style and watch out for how much regen your car uses compared to its normal amount, since after a week of driving an EV in the summer you don't ever really touch the break pedal.
