ABRP Reference Consumption

[J3t3r]

BTW, you can use a wireless ODB2 dongle to connect to ABRP and collect realtime efficiency values for your own vehicle/driving style. I ran it in my MME for a few weeks to get better data for trip planning. Still doesn't help with the charging curve inaccuracy but frankly I am more concerned with planning the appropriate stops than the estimated charge time.

Do you know which brand of ODB2 Dongle works with Rivian and ABRP?

You can't do it that way with the rivian.

I used Kyle's 2.33 numbers for my "simulations". Based on this I am confident I can change to the large pack. I know his numbers were at 70, not 65, but I like to have that little bit of extra padding. Also even with the conservative charging curves, the difference in even my longest trips (8-9 hr drive time) was only about 30 minutes for max to large, definitely not worth the $10k, at least to me. Towing is where things get dicey, but again, not that much better with max pack for my normal tows based on the numbers Kyle was seeing as well (using 1.05 mi/kWh, I think that was the number he had for the enclosed trailer test, again at 70 not 65).

Is kyle’s 2.33 on conserve or all purpose?

I think that was conserve, but to update my previous post, I found on my truck with 21" wheels, 3.01 was accurate for conserve mode.

Here’s the link to the Out of Spec range test video between the 20”, 21”, and the 22” tires.



reference consumption is as follows.

20” = 2.14 KWh/mi
21” = 2.4 KWh/ mi
22” = 2.3 Kwh/mi

I found the current ABRP defaults to be sufficient with my 21" R1S. It's set at 2.59 mi/kWh @ 65 mph

If i wanted to benchmark this myself, especially since I want to know what the value is with my cargo box, do I just drive onto the freeway and do 65 mph for like 5-10 minutes? I think I can get the data off of TezLab and try to do some kind of average between data points.

Has anyone done their own benchmarking?

Try this:
Get up to your desired speed (65/70)
Reset trip B (using Driver+ is helpful/safer)
Drive around 10-15 minutes at same speed.
If possible, choose a day with weather between 60-80 F, no wind, relatively flat terrain. This can be difficult sometimes.

Take a photo of MPK and any other metrics (time/distance). Temps below ~60 will have a negative impact of 0.1 MPK per 7F (plus/minus). Elevation/air density also will have an impact (check other threads for more info). If you are curious you can check nearest race track for info:

TLDR: A recent highway test I conducted resulted in 410 Wh/mi (aka 2.44 mi/kWh) as the correct A Better Route Planner Reference 65mph consumption for my 2022 R1S with 20” Pirelli AT’s and roughly 6,000 mi. on the odometer.
Ride Height: Standard.
Drive Mode: All Purpose.

Longer Version:
I started at the Phoenix RAN charger after charging to 90% and then set off for Flagstaff.

I carefully maintained 105% of the posted speed limit. There was little traffic so I was able to maintain a consistent speed.

I started at 90% with a nice warm battery. I ended at 17%. Tire PSI were at factory settings. It was a nice mild evening in the desert but I needed a little air conditioning during the first 45 minutes of the drive which may have used 1-2% in my experience.

After arriving in Flagstaff the Rivian showed that I had used 73% of the displayed available battery capacity for this trip. I then adjusted ABRP with all relevant variables including real world weather, traffic, extra cargo weight, and starting battery temp.

Then adjusted the Reference 65 mph consumption setting until ABRP predicted trip energy usage matched my real world result of 73%. 410 Wh/mi was the setting that resulted in a match
