I have read a few posts and I am still not 100% of what to expect when using the departure time setting (A/C On) in terms of when the charging will start. I expected the charging system to project the time needed to charge and delay charging until the remaining time was just greater than needed to charge to 100%. This is not how my ED is working. Regardless of whether I choose immediate charging or a departure time, my ED starts charging as soon as I connect the plug from my Level 2 charging station. The A/C feature does start 30 minutes prior to the departure time. I am using an Eaton Level 2 charging station, and I don't know if that is a factor or not. I assumed that the ED would be in control of when charging starts, not the station itself. I have only had the car less than a week, so I can't recall whether or not the charging behaved differently with the supplied Level 1 charger. What I have noted, is the car A/C is much more effective in heating the vehicle on the Level 2 charger than on the Level 1 charger. Any insight as to how this should be working would be appreciated. I am also wondering if it is possibly an update that needs to be applied by the dealer. My car was an early production 2013, so anything is possible.
