So, on a whim I decided to look into how Tesla's Model S range calculator works. You know the one (3/4ths down):
Model S | Tesla Europe
Looking at the code, I see that first off, there's actually several data fields that you can't configure. They have 90D data. They have data on the effects of headlights. They have data on the effects of windows. They have a range field called "city", which one presumes is a start/stop city cycle of unknown details. And of course,one can always take their data, combine it with the known actual-usable-capacity data, and get Wh/mi on the vehicles. They also have three versions of the site - metric, imperial, and hybrid - each with datapoints, which you can combine to get a wider set of data. So, I'm attaching two spreadsheets that contain *all* of this data, including the hidden data, so people can feel free to look things up, make comparative graphs, and so forth
Graph ideas (I don't have time at the moment):
* How does each model's energy consumption compare in the same weather/window/light/ac/heating conditions?
* How do windows-down effect a given vehicle's energy consumption under a specific set of conditions vs. AC?
* Same for lighting, and heating
One could also adjust the curves to get a pretty good guess at Model 3 data (for example, range vs. speed in different weather conditions).
The other curious thing I found is this:
https://www.tesla.com/tesla_theme/js/models/data/config.json
There's a ton of fields in there describing something *much* more elaborate than the simplistic range calculator on the page. It sounds like they were perhaps looking to do a primitive of what a company I ran years ago had offered to them as a feature That is, simulating actual drives. There's data in there to figure out how long charges take, with fields like:
"plugEfficiencyStd": 6.48,
"plugEfficiencyMid": 9.94,
"plugEfficiencyMid_JP": 6.743,
"plugEfficiencyHi": 19.85,
"plugEfficiencyHi_JP": 13.65,
There's fields discussing summer vs. winter. There's something involving estimating your savings vs. a gasoline car:
"savingsTitles": ["PETROL STATIONS", "OIL CHANGES", "SPARK PLUGS", "SMOG CHECKS", "TIMING BELTS", "FUEL FILTERS"],
There's a list of fuel prices for different countries. There's lots of animation data - including charging animations, savings animations, and my favorite, road trip animations that have fields related to cows:
"cowLeftStart": 7138,
"cowLeftStop": 7618,
"cowRightStart": 7138,
"cowRightStop": 7618,
"cowRight2Start": 7138,
"cowRight2Stop": 7618,
It'd be interesting to know just what they had been planning
Anyway, just thought I'd share
