I have been a SR+ owner for just under a month ~2500 mi including a ~700 mi road trip. While the Tesla routing works great and the energy graphs are surprisingly accurate it doesn't provide any planning capability for a longer trip (with breaks etc), also the SR+ is not an option that is available on the Tesla routing available online, so even fewer planning options.
A better route planner is the only real option I could find but the SR+ is in Alpha and the default parameters it uses for the SR+ are pretty inaccurate. So I have done a couple of experiments to try and find the right values to use mainly for the reference consumption at 65mph.
The experiment:
I did a point to point drive from my home to a restaurant that I like particularly in NJ. It is about a 65 mile drive. I did this drive twice with almost the same weather and at about the same time of day and traffic conditions (same direction to keep as many params the same as possible) with normal driving (no unnecessary hard acceleration/braking) on the ~5miles of streets and on the ~60 miles of freeway tried to keep auto pilot engaged at 70 for one drive and 75 the other time. While it was easy to maintain 70mph (sit in the center lane and watch everyone cross on both sides ), at 75mph there were a few times when autopilot slowed down because of the car in front and some other cases when I had to manually cross the car in front by accelerating a bit to get back to my cruising speed. I don't think those deviations from the cruising had a major effect.
Results:
Freeway cruising @ 70mph:
I used about 25% of battery - Exactly 60 miles consumed from my driveway to the restaurant's parking lot.
Freeway cruising @ 75mph:
I used about 30% of battery - Exactly 71 miles consumed from my driveway to the restaurant's parking lot.
Using ABRP:
Now with this data I tried to go back to ABRP and plug in the addresses and the temperature, road conditions etc for the 2 drives (most of which was pretty much the same) and played with the Reference consumption and the max speed to get results that match both my data points.
The settings that seem to get me closest to my results are as follows:
I will try to use these settings for my upcoming trip to MA this weekend and see if they hold water and post an update.
Hopefully other SR+ owners find this useful and will provide their own findings here as well if possible.
