My next dilemma is learning more about how my BEV car is going to behave. And which car to drive to Grayslake on Thursday. If my calculations are correct, if I leave Cherry Valley at 100% given the projected temps in mid 30s we should arrive home with about 36% left in the tank according to A Better Route Planner. Shows just shy of 60 miles ea direction. And if what the vehicle has been reporting to me under these colder conditions holds true, I'm thinking it may be more like 20%-25% left. So a decent "cushion" there. But now with some fairly cold temps on us, I am seeing range has dropped due to using HVAC and the cold. From about 225 miles in more "comfortable" conditions down to about 180-190 miles.
Of course other conditions i.e. speed and headwinds primarily do change things a bit.
Saw that last Tuesday when driving to O'Hare to get daughter. On first glance looked actually better than I expected. Pleasant temps car was comfy with just the heated seat and under dash infrared heaters and HVAC (heat pump) off. 70 mph cruise control. Couple "bursts" when needed to 80+.
But, on arrival at O'Hare, it began getting colder. and wind picked up. I could watch range and miles left dropping like a rock because of heading right into the wind, highway speeds and HVAC on.
Now this AM I went out to get grandson. Inside garage about 47F got outside and temps were 24-25. Range then only showing about 160.
Same thing happens to ICE vehicles as well. Really shows up on Hybrids as well. My Highlander in cold would drop from avg 18-19 mpg down to 14 or so. But we don't think about it as much with ICE due to ease of fillup.
But, I am still learning the quirks and behavior of our new BEV
