Took our '16 SV up to Mt Evans yesterday. The Trip planners (Green Race 5 and evtripplaner.com) said we would make it on one charge, but it would be close. The Nissan Web trip planner has a bug and kind of craps out half way up the mountain.
So we left yesterday at 8:30 with 27.4Kwh on the battery. We being my wife and three kids. We live by City Park. Never went above 60 going there, AC off, fan on, stereo on, ECO mode, and in B-mode. Temps were in the seventies when we left.
Stopped and had breakfast @ Idaho Springs and used Beau Jo's charger to add 8Kwh to the battery.
Made to the top with no problem with 8.9Kwh on the battery. It was a pretty day and it was crowded.
On the way down we stopped at Echo Lake and did a couple mile hike to the Idaho Springs Reservoir. We arrived again in Idaho Springs with 16Kwh, regenning 7.1 Kwh. Pretty cool.
So the upshot is we could have probably made it without charging, but it would have been close. The Green Race 5 planner came closest to accurately projecting the trip's energy usage.
