Interesting. I think I might set a 10:00 AM departure, since I rarely drive anywhere before then. And on days that I do head out a bit earlier, at least the battery would be partly pre-conditioned. Wish I had room to keep the i3 in the garage, but don't want to move out either of the other 2 vehicles.
This is good info. Thanks!
Just something I came across through trial and error, because I too have an undefined departure schedule, daily.
So I generally leave the pack to charge to about 90% full, and then EVSE cuts off. But before departure I go in via the app and start charging again. Typically I'll do this about 30-40 minutes prior to departure, and I've noticed pretty much the same range doing it this way, rather than setting a preconditioning timer. It also saves electricity, because you're using electricity to both fill the pack, and warm it (charging batteries warms them up significantly). For more data points, I've noticed the car still pulls 6+kW until about 94-95% then tapers down to 2.5-4kW until 100% full. When I used to do the precon, i believe it pulled about 2kW from the mains to heat the battery. I'd rather put that 2kW into the pack and heat it at the same time. Give it a try.
Am I trashing it?, absolutely, but with love, like every other BMW I've owned.
Rondel stands for something, and I fully utilize all the non neutered abilities its got.
Takeaway. This is an amazing piece of engineering. And I'm not impressed with 'stuff'
