My 90D new in February of this year has just completed 12,000 miles. My average power consumption over this distance is 285Whr/m. On my daily run to work and back a distance of 26 miles my average consumption has been around 260Whr/ m. Suddenly this has now jumped to 340Whr/m! There are some changed circumstances. I have 3 tyres at 41psi and one at 45 psi (to be balanced out tomorrow). The temperature has fallen from around 60F to 50F, I now have V8 software..... What does the power consumption display actually reflect? Is it tractive power consumption only or does it also include the HVAC load too. Cold weather is always meant to reduce battery performance. Is this automatically calculated in the percentage battery/miles display or is the load power display upped to compensate? Can anyone answer any of my questions or give me peace of mind that there is nothing fundamentally wrong with my 'Tessie'.
