That is about right for the 2017 PP on L2 EVSE. I was charging 6.3-6.7 on L1 EVSE when it was less than 1 year old. Many who have used L2 EVSE indicated a 5-10% efficiency benefit, so the actual full charge on L2 was 5.8-6.3kWh. Considering ~10% capacity loss after 7 years, 5.3-5.8kWh seems pretty good to me.
When 100%, the tracttion battery is at 84% When 0%, the tracion battery is at 15%. From 0 to 100% the battery will take 6.1 kWh, measured from the meter.
Thanks for all the folks updating and correcting what I said here about running the traction battery completely dead. I was clearly out of date.
