Trying to get to grips with T7 PHEV Aux Heater

[sidepod]

Different fridge on the T7 so Transporter fridge power consumption may not relate.

Indeed but I’ll bet it’s not far off? You’d struggle to get a fridge to work with anything less than 4A.

The % calculation is a spot calculation and can be very inaccurate. What voltage are you seeing? The voltage is accurate.

Aproximately between -0.5 and -5 A showing on the back panel. But honestly I found out that It IS not as I described since the bluetooth was also on. Thesw days while on vacation i could see that consumption is not that high. I would say around 20% every 12 hours...Thks!!!

I'm not sure that works for li-ion batteries like in the T7?

It should work but there is only 1.36v difference between 100% SOC and 10% SOC. The voltage is a direct measurement whereas the % reading is a spot calculation based on the voltage and power consumption at the time of the reading. The power consumption being presumed to be continuous rather than intermittent.
