This title is a new one on me. It happened a couple of times this week, on the way to NY once and on the way home tonight once.
First of all, I too the eco route home, some highway, some country road. I was on 15 N and I passed 91 and it wanted me to stay on 15, but then all of a sudden "highway ends" I didn't expect that, turns into shopping strips with lights every mile or so. I looked on my phone and found an EV charging station close by and decided to stop there for a little juice. 20 minutes I had a snack, used the bathroom, And charged from 89% to 99%. The first leg was 73.3 miles, 49mpg and only 11% battery used.
The second leg I went straight through 15 lights and all, then onto 84 for several miles with rolling hills, saving the battery for later the car started out close to 50 and dropped to 40.4mpg by the time I got to route 191 my exit for the country road home with 95% battery to start.
I enjoyed the rolling hills, steep 9% downgrades and was able to recharge the battery back up to 99 to 100% on a couple of occasions. I used the engine for climbing as it was hot already and at some point about 30-35 miles out I decided to EV it and use up the battery.
About 7 miles from home with 5 miles remaining showing in the battery all of the sudden the engine was running - it had not been for a while. I quickly switched to the leaf screen and then to the car icon before the oncoming stop sign and caught the description in the subject above. Anybody know the reason for that?
a) The main battery was not dead
b) Climate control was off
c) The engine had been used quite a lot and was already up to operating temperature.
d) I did not over throttle the car, acceleration bar was at full blue.
Anyways, I gingerly creeped into the big-Y here locally in my town ith 1/2 a hybrid battery left, perfect, and killed the mpg number at 71.9 for the 2nd leg of 86 miles. I'm recharging now while checking the forums and writing this question. Gotta pickup some ice cream before heading home gas free.
Total trip burned 2.62 gallons of fuel for 60.8mpg average.
