I think I have the solution to your problem. I just started doing this a couple of days ago and it works great.
When setting up your charge timer, turn it on, set it to 80%, enable it for all days in the week and set the start/end-time
What this means in practice is that the "timer" is on at all times
and whenever you want to charge it to a 100%, you just turn the timer off.
Also, to confirm that the timer actually starts charging the car immediately, listen for a second beep after putting the charge cable in. So - put the cable in *beep beep*
, 2 seconds later, *beep beep*
- and it's charging. You can also look at the dash lights.
I have a 2015 european Leaf so my menu system might look different from yours (although probably not).
