A different answer/consideration to the same question: doesn't hurt to "sit" at 100% when's it cold (for pre-heat), but don't do it when it's hot (for pre-cool). Personally, the only pre-conditioning I have ever done is pre-heat.jwarner07 said:I'd like to keep my Leaf plugged in for pre heating/cooling, but do not want to add charge. There seems to be no way to do so, any advice?

The EVSE only charges the battery, however it's quite obvious that with L1 connected, the ECU is managing power use so that the the 400 volt pack output does not exceed the input from the EVSE. This makes sure that the charge level you were expecting, is also what you have on hand when you unplug if using L1. With L2, you get more watts going to heater (like 3 X more) and you do have a bit left over to charge the pack as well.
You are limited to 1000 watts max from the heating system when plugged in with the OEM charger at 120V (L1) as you can see from the first two pics I posted. That may be adequate in warmer climates, but if your target cabin temp is 20 C, and the car has been parked overnight at -25 C ambient, the car will not reach the target temp. I had the LEAF outside last year for about 2 months during the coldest part of winter (average -18 C ) and the cabin was never at the set point preconditioning at L1. L2, no problem.

Please clarify that last part. Since all power for preheating comes directly from the traction battery, preheating in frigid temps should be equally effective whether using L-2 or L-1. Using L-1 should result in a substantial net loss of charge, but it should work. Unless they have made a change to this in the Gen II Leaf...
A/C-HEATER TIMER (Climate Ctrl.
Timer)
The air conditioner starts to operate at the time
of day and day of the week specified in the
settings. This pre heats or pre cools the vehicle
to a factory preset temperature in the passenger
compartment before driving while the charger is
connected to vehicle. This help reduce power
consumption from the Li-ion battery.
As the temperature is set to the factory default
setting, the user cannot adjust the temperature.
The A/C-Heater Timer (Climate Ctrl. Timer)
operates the air conditioner using power from
the charger. Electric power from the Li-ion
battery is not used.
The A/C-Heater Timer (Climate Ctrl. Timer)
function allows two different timer settings. Each
timer charge function can be set to activate on a
different day of the week.
Once the A/C-Heater Timer (Climate Ctrl.
Timer) is set, it automatically starts when the
set time is reached. It is therefore not necessary
to set the A/C heater timer everyday.

battery is not used.
Sorry about the darker LED "Power" light but it seems that finally it's the same orange color. I felt it darker because of the lights at my garage, but yesterday I activated it from the application connected outside and it's the same orange tone.LeftieBiker said:You can post a page of the manual - just not all of it. So you are in Europe? It's possible that this feature is present only in some European Leafs. I have never before seen anyone mention an extra function (darker LED for preheating) like you describe.
