I've been using Scheduled Departure so that the car will spend somewhat less time at a lower SOC, but I'm over-optimizing things.
For example ...
Let's say that I typically drive 50 miles in a day on average, and I charge to 80% each night. I charge at 25 MPH.
If I use Scheduled Charging and start at midnight (when off-peak begins), and leave at 9 AM, the car will be done charging at 2 AM and sit at 80% for seven hours (2 AM to 9 AM). If I use Scheduled Departure, it will be at 80% for very little time (presuming I leave at 9 AM).
Over five years, this means the car will sit at 80% an extra 12,775 hours (7 * 365 * 5).
The problem is that occasionally I drive a lot in one day, so I have to adjust things so that it won't start charging before midnight. I think I'll just change to have charging always start at midnight. Thoughts?
