On couple occasions I noticed that my Leaf charged itself to 100% when timer was set to 80%...
I suspect is it is because of the preheat or something... haven't noticed this before... Anyone knows if Leaf actually charges when preheat is on?
My pattern of usage on this 2 occasions was similar:
I haven't touched my timers in a while, and I have one timer on for all days, with no start and end time at 4AM.
The day before: charged to 80% (using timer), drive turn on timer override, charge for about an hour, drive to almost empty.
Morning, charging timer supposedly cutoff at 80% at 4AM. I had a preheat timer set for departure at 6AM, but I was leaving at 8AM those days, so when I come to the car at 8AM everything is off, but battery is charged to 100%...
The only thing that comes to my mind is that because of mild temperatures heater is not drawing a lot of power, but it actually maxes charger capacity, directing the leftover to charge battery. I know that if you do preheat leaf can draw additional power from battery if needed, even when connected to EVSE, does it work in reverse as well (if heater do not need power charger charges battery instead of discharging it)?? I wasn't expecting that...
I'm pretty sure I didn't hit override timer button as I heard EVSE relays clicking twice, to connect and disconnect... And it happend twice both times when I was departing late...
Any ideas?
