Part 2 of my Road Trip
Round Trip: Cabin to Ski Resort
This morning I drove the Lightning to our local ski resort.
21.7 miles (no snow on the roads - it's still unseasonably warm here since last storms)
2800' elevation gain
Started at 80% charge, arrived at 67% charge ~ 17 kWhr
For some reason the display below didn't calc the efficiency (it was on the dash display, and I thought it was closer to 1.0). But, assuming the above data, this is about 1.3 mi/kWhr.
Note that had preconditioning on before I left. Nice warm cabin and battery. In fact, for the first few miles of my trip, the "Exterior Temperature" percentage was like 3% as was the "Climate Use." So, I would agree with the Ford folks, PRECONDITON your vehicle before leaving!
[Next trip to ski resort I will disable preconditioning to see how it effects these data]
On the way home, ahhh, the magic of gravity. I left at 67% charge and arrived home at 67%, yeah, basically no net battery usage. Note the pic on the right. 0% was used for driving! The energy regenerated replaced all the energy that was used for the motors. Of course, I'm a firm believer in the laws of thermodynamics, there was a loss, but I'm sure that the calcs the truck is making get messed up with such low usage vs. distance. The truck basically thought all my energy was being used to warm the cabin, the battery, and power my radio.
Per the computer, I got a whopping 12.4 mi/kWhr! Someday, all drives will be so efficient

in case the engineers there find this interesting.
