Since I got my car in March 2020 I've traveled a few times between my home in Frisco, TX and Fayetteville, AR and know pretty well when and where to stop to make it a pleasant drive. Going through Oklahoma takes some careful planning but there are few good Chademo chargers along the way and A Better Route Planner is helpful.
On my recent trip back from Fayetteville yesterday I got in major trouble and I had to make an emergency stop to charge and still only made it back home with 2 percent left. The super low efficiency caught me off guard. The energy graph has impressed me many times on how accurate it is at predicting usage but this time it was off the charts. Every few minutes it kept dropping another percent.
Here are some stats from TeslaFi:
Distance 324 miles
Altitude loss 739 ft
110.89 KWH used for an Wh/mile of 361
Average speed 58 mph
Outside temperature between 86-98 F and no precipitation
light wind between 10-13
SW 2021.12.25.7
In comparison the opposite direction driven the day before with at least 200 lbs of additional weight (moving my girl to college) used 93.49 KWH (296 Wh/mile) with an outside temp of 88 F, That is a difference in efficiency of 22%.
Another point of reference is my last trip back from Fayetteville in May:
Same distance and altitude loss
88.99 KWH used for an Wh/mile of 269
Average speed 62 mph
Outside temperature between 71-76 F and no precipitation
light wind between 10-15
SW 2021.4.15
The difference in efficiency is 34% for the exact same trip and that does not make sense to me.
My lifetime average is 293 Wh/mi over 14,470 miles.
Any idea what is going on?!?!
