Over the last month or two I have noticed my range reducing and lately dramatically reduced.
My car is a 2015 P85D with a little under 60,000 kms traveled and had a genuine range of around 340km (tested) when i purchased it.
After charging my car to 90% (as usual) and driving locally for 2 days my trip display shows:
73.1km travelled, 19.4Kwh used and 265Wh/Km (I am a little heavy footed so the high power usage is not too much of a shock, although a little higher than I would have expected) and my current state of charge is 52%.
I am no expert but here is my simple math: (feel free to tear it apart - all responses appreciated)
90% battery is 76.5Kwh
76.5Kwh (90%) / 19.4Kwh (used) = 3.94
73.1km * 3.94 = 288km range on a 90% charge (assuming zero phantom drain)
But I have used 38% of the available charge, so estimated range is actually:
90% (available) / 38% (used) = 2.37
73.1km * 2.37 = 173km range
Tesla says this is because it is cold and more power is required to heat the battery and to heat the car when in use. They also say the battery is only down by 4% from new. I have been advised to charge to 100% and do a long trip to a low % (not specified but I assume around 10%) and then do a full charge to reset the battery.
I have had the car for 3 years. When I first purchased it I had to park outside as the garage was full of junk. During winter of the first year I traveled from home to Wodonga (328km) leaving at 5am with temperature below 10c with a 100% charge and had 5% left on arrival.
For the last 2 years the car lives in the garage and I would not even attempt that trip now.
Am I missing something basic or does this battery have an issue?
