You motivated me to check the spreadsheet where I record the charging history for my 2016 SE. Over a 2-year period:
Energy used : 2,837 kWh
Miles driven: 9,911
Efficiency: 3.49 miles/kWh (116 mpg equivalent)
For me, the range loss since I replaced the Ecopias with a set of CrossClimate 2 tires is about 5%. The Ecopias were 5 years old and had about 25K miles on them. I've had the CC2's for about 6 months and have driven 2500 miles on them.
If you look at the user reports in the Enel X portal (https://home.juice.net/Reports/Sessions), what does it show? If I leave my e-Golf plugged in to my JuiceBox 40 overnight, there are a number of short 45 second entries after the initial charging session has ended where no additional charge is...
