I am going to charge my P85D to 100% for the first time early tomorrow morning. I'd like to time the charge so that it ends just before I plan to leave, as the less time I leave my pack at 100% SOC the better. I'm sure a lot of you will feel the need to come and post to tell me that a few hours more or less at 100% SOC isn't going to make a lick of difference in the big picture. I'll save you the trouble and tell you I understand that. I'm still interested in timing things as optimally as I can.
So, that being the case...
I have read that people believe the pack management software may do some interesting things at the end of a 100% charge that it doesn't ordinarily get to do when charging to a lower SOC, and that these things take time. I know there is debate about whether it is pack balancing or not, etc., and I'm not trying to open that can of worms. All I am trying to find out is how much additional time I should factor in for whatever it is the pack management software might like to do this first time I am charging to 100%. I'll have about 8000 miles on the car at the time. We ordinarily charge with pretty deep cycles, and charge to 90% almost every day. A typical day has seen anywhere from 100-190 range miles being driven, depending on the weather and the day.
My plan is to charge to 90% before I go to bed, and then set a timed charge for the last 10%. I'll be charging at 56 amps, and that last 10% or approximately 30 miles would ordinarily take approximately 45 minutes or so. I want the car ready to go when I need to leave in the morning. How much more time, over and above the 45 minutes it would normally take, should I allow for whatever it is the pack management software will want to do?
Again, if you are inclined to tell me to just set it to 100% tonight, and not worry about it, please don't. I fully understand that I could do that. I'd just prefer not to.
Thanks!
