Tesla API and battery data.

So this is pretty cool. Tesla API

I can ask Tesla all sorts of information about my car via their REST API.

I have a brand new Model 3 SR+ and I'm wondering how it computes batter_range and ideal_battery_range, which in this case are the same at 212.62, and which are 3.38 miles off of the advertised range of 90% of 240.

When picking up the car I mentioned to the sales agent that I had actually wanted the aero wheels because of efficiency (I have the 19s) and he mentioned that there was headroom in the battery to compensate. Not sure I believe that, but I'd think it would be prudent for Tesla to actually ship a battery that, when brand new has a few percentage points of extra capacity. (Under promise, over deliver)

I'm curious about the timestamp returned. Does everyone receive the time as Pacific time? I took a road trip from So. Ca. to Louisville, Ky and recorded the vehicle data when I supercharged. The timestamp is not based on car location. Again, just curious.

It is a Unix timestamp, the amount of time since Jan 1 1970 00:00:00 UTC. In this case, it is in milliseconds. Then you offset to your own timezone.
