When we bought the car a year ago, we got a GOM value of 107 on a fast charge. Currently, on a full charge (120v) we’re only getting 77 miles on the GOM. Why has our GOM on a full charge dropped so precipitously? Does cold weather have anything to do with it?
Edited your post slightly.
The guess-o-meter is crap. Please see viewtopic.php?p=271853#p271853
The GOM value is only your "range" if ALL your future driving is exactly like (in terms of efficiency) whatever recent driving history the GOM uses to come up w/that not very helpful value. Your recent driving may have nothing to do w/your future driving.
Efficiency is worse in colder weather. Rain and snow on the road further cuts efficiency. Running the heater consumes more energy than not running it as there's little "free" waste heat on an EV and Leaf doesn't scavenge that.
If you want the GOM to be higher, go down a hill, turn off the heater and AC and charge at the bottom of the hill. I guarantee you it will be high. Want it to be low? Drive very fast up steep hills and charge at the top of it.
