In my 2015 Model S 70D with 19" slipstream wheels; the onboard trip planner had been surprisingly accurate at estimating remaining SOC on MCU navigation on the original battery. I've made a couple of trips hitting some of the same chargers before and the cars trip planner had been quite accurate to what I would actually have when I reached the destination(I normally drive 5-10 over posted limit).
For clarity I am talking about this estimate you get in the MCU and to how close it actually was:
My Pack was replaced in January(Service center put in a 75, and updated car to show 75D) and on the next road trip(Over 1600 miles total), when I put in destinations, the estimated charge left at next stop would be off by up to 20% which I find odd and a bit of a pain since it made me charge more at some sports out of concern.
Examples I remember from my last trip from Tampa,FL to Marion NC and back after the battery replacement(this were the estimates shown by car when we were leaving):
Marion, NC to Columbia, SC Supercharger made it with 23% remaining
Onboard Trip planner estimated 4% Remaining and said to stay under 65(which scared my Girlfriend)
"abetterrouteplanner" estimated 19% Remaining
For this sector I knew I'd make it since we left with 100% and I didn't want to have to stop again
From Kingsland, GA supercharger to home in Tampa, FL made it with 9% remaining.
Onboard Trip planner estimated negative 9% Remaining
"abetterrouteplanner" estimated: 5% Remaining
For this sector below my girlfriend drove and she's notorious for a lead foot and stepping on it to pass slower people:
Savannah, GA Supercharger to Columbia,SC Supercharger: Actual-16% remaining.
Onboard Trip planner estimated: 5% Remaining
"abetterrouteplanner" estimated: 19% Remaining
I saw an article on Electrek about the trip planner getting more "Sophisticated" and accurate. But seems that for me after the pack swap, mine went the other way(I have 0 complaints about the new pack, only posting about noted differences)
I've mostly just adjusted- when supercharging and the car estimates 1% remaining at next destination is now when I leave to make it there with at around 15% or more remaining...
How accurate is the onboard trip planner for estimating how long to charge to make it to the next stop for others?
