Hello everyone.
I recently did a 3000km one way trip and did lots of testing on my driving / range.
And I have a question that bugs my mind.
I own a 2016 P90D, 772hp version. 81000km (50300 miles) on the odometer.
The specs I see on the internet states that my rated range is 449km (279 miles).
Now.. I charged the car to %100. Then I drove with 100-110km/h (62-68 miles/h), Range mode and Chill mode on, aircon off, around 24 Celsius (75 F), I did around 438km of range (272 miles) with one charge. Which looks really really good considering the car has done 81000 kilometers in 5 years and the rated value is 449km right? %97.55 of the rated range after 5 years and 81000 kilometers!
Well, maybe wrong? Let me explain..
In this part of trip, I stopped for charging after 355 kilometers and it showed another 83km of range remaining, which I think was quite realistic.
According to the car, in this 355 kilometers, it consumed 56.1kwh, 158wh/km.
So, I should have had another 90 - 56.1 = 33.9kwh remaining right? Very best case scenario.. I mean, aircon was off, it was day time, no other serious consumption was expected. But lets say I lost 1.9kwh for keeping the car on, multimedia system, battery cooler etc. (That means around 0.54kwh consumption for 3.5 hours, just by being ON)
That leaves us a 32kwh in the tank.
Now pay attention, the average consumption in the last 50km of that 355km was 147kwh, even lower than the average of the whole trip. Tesla technician told me that remaining range is calculated over the average of last 50km and the SoC.
So..
32kwh * 0.147 = 217 km. That would be the remaining range I expect IF I did 355km with 56.1kwh.
Instead I got 83km. What does that mean?
83 x 0.147 = 12.2 kwh SoC.
So after spending 56.1kwh on driving, and guesstimate of 1.9kwh on multimedia etc., my remaining charge was 12.2kwh instead of 32kwh.
56.1 + 1.9 + 12.2 = 70.2kwh.
To me, it looks like my battery capacity is down to ~70kwh.
I repeated this test with different driving conditions, aircon on / off, range mode on / off, sport mode etc.
All my calculations show ~70kwh of capacity.
Unless the car really uses 20kwh in 3 hours just by being powered up...
Now.. I do get the %97.55 of rated range if I drive easy on the highway.
However, I feel like I should get many more kilometers out of my car if it is really 90kwh.
Expected range calculations considering nothing else using up battery:
90kwh -> 90 / 0.158 = 569 km (353 miles)
85kwh -> 85 / 0.158 = 538 km (334 miles)
80kwh -> 80 / 0.158 = 506 km (314 miles)
75kwh -> 75 / 0.158 = 474 km (294 miles)
70kwh -> 70 / 0.158 = 443 km (275 miles)
How many kwh could the car possibly use up by just being ON during this 3.5h trip, with no aircon, no headlights, nothing except the multimedia system running?
To me it looks like I lack ~20kwh of my battery capacity, which is %22.22.
And I still get %97.55 of the rated range.
I am confused..
Any inputs?
(Tesla warranty on the battery promises %70 of capacity over 8 years. Losing 22.22 means I still got 77.78 so I can't claim warranty)
