Several people have tried to explain this. But I will have a go as well. Manufacturers legally have to tell you the WLTP range. It's like the ICE mpg at a constant 56mph. good for comparison no good for actual range. In the car Tesla show the US EPA range which is better and is probably achievable on a warm day on an A road but certainly not on a Motorway in November. Warrentee is based on loss of battery capacity not range. If you want to check that you will need a wiring adaptor. Dongle and the Scan my Tesla App.
Thanks all I am not trying to be difficult. (I am a process engineer/.scientist).
Ok CAPACITY and this is my big point I dont know what mine is officially so suspect it 75KW as some people previously pointed out.
Ill look at the dongle and app but not a general thing for most people.
So now we are cooking, Just to get to basics as people may have forgot with MPG and petrol car I know the tank size as per manufacture say 50l and fill up run a few miles say 300 miles at 10% left and fill up again to work range works out t 31 mpg say.
The difference is that the tank size does not begin to reduce shrink so next few years I can only put in 40l and run 250 miles still does 31 mpg No I qill will always put in 50l. range may drop as efficiency drops... different story
SO Using charging eliminates a roads, temp, speed rain, tyres, acceleration. If at 50% I put in XXkw to 90% will give a capacity value in kw.
So if my capacity is 75kw, 70% is 22kw charge loss or 12kw from 40% to 90% so instead of 37.5 kw if it only adds 25.5Kw its bad
Ill know this as my range will have dropped big time by 48 miles in the 40 to 90% as I do the same trip every day.
As MrT3 states Tesla does not state the battery size so how can we make a claim.
