Total battery Kwh usage. If you sit in your garage with the heater on, then the only use of power is to climate control. hence 100% usage. If you drive it with climate controls in use then you are using 18%. If you did not use climate control when driving you would theoretically get 18% more miles out of that chargeWhen using Climate controls and it comes up on central display it says 18% or 100%. 18 or 100% of what?
I have gen 2 so it doesn't say anything when the climate control is on. It just had a little bar that fills up with manual fan. Only % is when u look at where the power usage is distributed. Sorry for the confusionI'm going to disagree with the first explanation.
It pretends to show how much of the total capacity of the heat or A/C the car is using. If I turn on the heat when driving at 70 mph the climate control will show 100% initially, then taper off. 18% might happen on fan only with the fan on 3 or 4.
I say it "pretends" because when my heater module failed (defective when new) and wasn't drawing anything according to the DIC, the climate controls still showed 100%.
Note: This applies to Gen 1. I have no idea if the Gen 2 does it differently.
