I had an email exchange with the developers of ABRP about how conservative they have the stops listed for the BMW IX 50. The reason they are so conservative on the stops is they do not have "enough" data on the BMW IX 50 as to its range and charging characteristics. They consider their data for the IX to be "Alpha" at this point until they have better data on charging curves and range. I did send them Tom Mahoney's test data from his test results on the IX50 on the State of Charge Youtube Channel. Apparently, there is a way to submit your range data to ABRP as you charge, and I plan on doing that on my upcoming cross-country trip from Baltimore to WA State (the week of July 11th).
I have a full route planned via ABRP, I have also cross-referenced this with the Plugshare app, and of course, I am going to use the route planner in the IX as a starting point. I will probably go conservative for the first few charges and see how the BMW IX does as I gain more confidence in its routing algorithms.
In the beginning, I am going to make sure I am no more than 250miles between charging points and then bump that up as I get more confidence. I am looking at this as big adventure and plan on just "enjoying the ride and experience". I am also planning on recording some of the trips on a go-pro camera and also plan on recording my charging sessions to see how well or bad they go.
Below is my first ABRP for the first 500-mile leg from Catonsville MA to somewhere around West Unity Ohio, again depending on how the first couple of charging stops go. ABRP has these VERY conservatively set with charging stops at 133, 119, and 193 miles. Depending on what the IX is telling me for range during the trip - I might be able to skip some of these or I might just do them to spend less time at a charger for each charging session. The IX might be able to do 300Miles - but unfortunately, my bladder is ranged at 220
I will keep the forum apprised of the trip if others are interested.
