I'm planning a trip to Asheville, NC and would like to know if anybody has experience going down Black Mountain. It is a very long descent and I was trying to figure out how many miles I could expect to gain from the top of Black Mountain to the bottom where the town of Old Fort is and where the expressway flattens out. I am interested in knowing because I wanted to charge my Leaf in the town of Black Mountain, probably up to about 80 miles worth of charge. If the car generates more than five miles worth of charge on the way down the mountain I am concerned it would be detrimental to the battery health.
Hopefully, this is the right place to post this question. If not, please forgive me!
