@NickFie As I said before my question is all just idle curiosity, not range anxiety or concern about cost. Here in the UK night time off-peak charging at much lower costs are available and we have a rate of just 5 pence per kWh between 00:30 and 04:30 (compared to 14 pence for the rest of the day). My wife's commute is 10 times less in fuel cost compared to our gas car. I've already warmed the car up for her before she left in the morning in the last few days; not needed the heated seats just yet
