The Tesla trip planner suggests a minimum arrival SoC, but users desire the ability to specify a higher, safer buffer (e.g., 25% instead of 11%) to account for unexpected traffic, weather, or other variables, ensuring they don't arrive with critically low battery.
We just returned home from a little road trip. On the supercharge session prior to our trip home, I set the arrival SoC level to 25%. Granted we stopped charging when we reached 24% estimated SoC and then drove home. We arrived home with 17% SoC. Speed limit was mostly 75 mph and we had FSD on with 80 mph max speed. While not a big deal, the 7% difference could mean not arriving home if not factoring in any sort of buffer for unexpected traffic or weather. The original charge stop wanted us to quit charging and arrive home with around 11%. Using the same SoC difference as what we experienced, that would have us arriving home with 4%. While still fine, that’s cutting it kind of close. What sort of buffer do you all consider ‘safe’? 26 MYLR. EDIT: to add some info for our trip, we initially left home at 95% and arrived to our hotel at destination at 33%. After doing some driving around in the area we then supercharged prior to our trip home. The trip planner, when choosing our home destination, had initially suggested to charge to have an arrival SoC of 11%. I upped it to an arrival SoC of 25% and quit charging when the car showed an estimated arrival SoC of 24%.
