Has anyone meaured the pre-heat power consumption, i'm only seeing 1.3 Kw, when pre-heat completes the car begins charging at 3Kw. I'd expect to see 1.8Kw ( battery heater ) and another 1 Kw for cabin heat etc
I don't know about exact figures but when mine is on a pre-heat, unfortunately just finished it here, my Owl shows around 33p/hour for the whole house and now that the pre-heat has finished it has dropped to 6.2p/hour. Whilst it was winding down I checked the power and it was showing 1.7kW but, as I say, that was it on the wind-down and for the whole house.
I double pre-conditioned this morning.
My powerwall reports that 3Kw was being drawn when I started, and lasted for 30mins, then droped to 1.2kw for 5 mins.
The Zappi reported that total draw was 1.65Kwh
