I thought to post this in the larger S forum but figured the Mid-Atlantic region would reflect better the SuC's in this area plus same weather conditions. I've found over the past several weeks that whether I'm at a full or relatively empty SuC location, my 2015 S 70D has been charging way slower. Yes its been colder out but many times I have driven 75-150 miles prior to charging so I don't think the batteries are too cold. Yesterday, I moved the charge limit from 85% to 100% in hopes the charger would sense I needed way more miles and wouldn't throttle slower. The charging rates (Bernards NJ) showed 36kW 125 mil/hr and in first 12 minutes I added 16 miles. Over the past weekend I charged at Marlton and received similar slow results. In both cases I had below 100 miles in battery so it did have a good charging buffer to get to 85% or in y'days case to 100%. At home I consistently get 29 mi/hr from 220 14-50 outlet. For historical purposes, I've only dropped from a full charge of 240 miles to 229 miles over past 4 years so that's only a 5% loss in capacity which isn't bad compared to many other comments. Question #1 Has anyone noticed similar slow charging recently, especially on older vehicles? Question #2 Can anyone recommend an App that tracks all charging sessions yet maintains security? At least with that type of App, the evidence backing my hunch would be empirical rather than a gut feel.
