Tesla Model S typical range calculation

Many people claim that typical range is based on 200 Wh/km. My own calculations show that it's 187 Wh/km on my car. And on the S60 loaner I calculated about 205 Wh/km.

I also did the same calculation as you did a few times, and I always ended up between 180 and 190 (don't remember the exact number). My current commuting average is 270 Wh/km... which means almost 50% more than the rated range! Needless to say that I don't count on these rated remaining distance to plan my trips...

Bjorn that is very interesting!

It is also interesting that the loaned 60 had a higher typical figure than the P85!   All things being equal the Wh/km (or Wh/mi in my case) should be slightly lower when calculating the range in a 60 not higher, due to the slightly lighter weight (the tyre pressure sticker on the car indicates around a 100kg saving compared to an 85)

I own a 60, and tend to agree with your findings here. I have managed an actual 195 mile trip, from a daily (not range) charge to 155 mile typical indicated. I did save energy because most of the journey was at 50mph (80km/h) due to roadworks/traffic, and I didn't need a/c, but still It just didn't seem to add up.

The typical line in my car's energy app is somewhere between 330-340Wh/mi (based on when the average line covers it, it's not on an exact graduation)  (206 - 212Wh/mi)

On this journey the statistics were: 194.5miles (311km) using 54.5kWh = 280Wh/mi (175Wh/km).
As I had zero typical* left that would indicate the typical usage figure in my car is actually based on 352Wh/mi. (54500Wh/155mi or 220Wh/km)

I did notice a drop in predicted typical range following the V6.0 upgrade.

On the plus side, 350Wh/mi (220Wh/km) is pretty easy to achieve, so it's fairly safe to plan based on the 60's typical range figure ;)

If I were a cynic I'd say this was on purpose to further enhance the perception between the 60 and the 85, where Tesla undoubtedly make more money ;)

*not strictly true as I added 10miles safety buffer at the services based, but returned home with 10miles. I didn't intend to get stranded ;)

Just did some small testing on my 70D. I end up with a typical usage of between 176Wh/km and 178Wh/km

This is based on two trips

Trip1: 97.6km (168km typical used), 306Wh/km, total energy used = 29.9kWh - method 1 (306/(168/97.6)) - method 2 ((29.9*1000)/168)
Trip2: 17.6km (37km typical used), 370Wh/km, total energy used = 6.5kWh - method 1 (370/(37/17.6)) - method 2 ((6.5*1000)/37)

method 2 will not show as accurate as method 1(the one you use), because you dont get the exact energy (6.5kWh when it should maybe been 6.599kWh) consumption.

I will try to see what my "line" in the car shows. I got a feeling its not "aligned" when i hit 178Wh/km

Anyway, this makes it hard to make a standard way for all cars to calculate how much energy they need to "stay below" on a trip.
((Battery range/destination range)*typical range multiplier) <-- if you want to use this you will need to know the typical range Wh/km - my car 178, your car 189, a random s60 is 205.
So is all 70s 178Wh/km and all 85s 189Wh/km

Excuse my english.

Bjorn my question to you is, what do you think about the toyota mirai ? what is the future? electric or hydrogen? btw love your vids! keep up the good work ;-)

Hi Bjørn
I know you have driven the 340km without any stop, but it is importen to say that if others make stop, or even overnighting, the lost in drain and others are not within the used kWh. 
Also, I'm not sure, if heating, when not driving is within the kWh. Ex. If you are parking, and have heater on, that kW use buy the speedometer, show kW use on the heater, but no chance in kWh use on driving.

Hi, i really like your videos about Tesla driving, Nimber, trips and dating.
But i think your calculation have something wrong about 212 Wh/km / 1.135, which means you think your car's typical consumption of the power within you driving is 186.7 Wh/km, right?
Then how could your car calculate that it can drive 386 km but it just can drive 340 km actually?
So maybe it means the avg. typical consumption of the power within you driving is more then 212 Wh/km.

[SorenKurgan]

sorry but arent your calculation backward?

you loose 386 range, but has only driven 340, so you spend more that typical?

[Mejoerg]

Thank you for your video! But your calculation is wrong. It is not a straight line passing through the origin, but by 8 kWh. With that in mind come out exactly 200 Wh / km. I have repeatedly verified with my consumption. Greetings.
