Had the opportunity to do another range charge this morning. It finished at 245, up from 244 last month.
One thing I still don't understand is the balancing. Unlike the previous range charge, I watched this one closely on the mobile app. I saw it hit the "1 min remaining" mark at 245 miles. It must be balancing now, I thought. The charger power hovered between 1-3 kW during the next hour. When it was finally finished, the balancing had added a grand total of (drum roll).... 0 rated miles! It still had 245, exactly as it did before entering the balancing period.
Where did this power go? I don't see how the car can still be pulling power and not be adding range to the pack. Balancing should only increase your max range by pushing charge around the cells to those that are at a slightly lower voltage. But, alas, that is not what happened today.
