I am a new clarity owner and learned a lot here - thanks. I have read all the preconditioning thread but still don't understand why it is working only on L1 full charge but works on L2 either full or not. Or how much power preconditioning use. So I did a little unscientific experiment and here is what I found out.
While plugged at L2 with battery full, I preconditioned the car. Temp outside is 46 and 60 inside according to app. At 212v, the car draws current between 4.8A-5.8A on the first few minutes then sometimes goes down to as low as 3.2A. So it is drawing around a max of 1.2Kw to precondition (heat) the car. On L2, power is split between climate control (1.2Kw) and charging the battery (5.4kw max). However, on L1, it just redirects the power to the climate control since battery is already fully charged. I would think there is some minimum power (1 kw?) required to charge the battery. So why not allow L1 preconditioning on battery that is not full? I think the logic here is to not enable preconditioning since power on L1 is just enough to charge the battery. Battery/Power management control module probably prioritize charging than sending power to climate control.
Now the only way to test this theory is to limit L2 power to 1kw and see if preconditioning still works. Now if only I have a transformer to test this out.
What do you guys think?
