Have you placed the decimal point correctly? The Energi charger draws about 13A; mine is drawing 3.114kW out of the local level 2 station (3114W/240V = 12.9A; the volts are a guesstimate). I'd be very surprised if the regen can approach that value.
I was also under the impression that the ticks on the gauge are 5kW each, so a max 32A propulsion draw (6 ticks) is about right.
I believe so, i set the xgauge to what i was given, but i can double check. Sitting idle with no load is about 1.6A. Since mine is a hybrid it may act different, or maybe needs a different config for the xgauge? Plus the Amp reading might be different, as i'm assuming its reading is directly from the battery, which is DC, so the Amp reading from the Charger on AC would be different than the DC on the battery side.
How much is one of these, $160?
This is the one i bought http://a.co/6bFqKn0
