We left Yreka at 6:14pm, planning to stop for the night in Grant’s Pass, only about 80 miles away. We had 168 miles of range left, which we figured would be plenty, even with some mountains coming. Thankfully it was down to 77 degrees outside because of the clouds and sprinkle.
Soon we reached the climb over Siskiyous ( we only knew this after the fact, we knew some mountainous terrain was coming, but we didn’t really have any details ). This extremely blurry picture ( complete with reflection of my knee ) is trying to show you that we climbed for over 5 miles using an average of 569 Wh/mile ( watt hours per mile ). At that rate the range of the car when completely full would have been around 80 miles. We were slightly under half, and the estimated range plummeted quickly and showed that we would not make it to Grant’s Pass.
This extremely blurry picture shows what the descent on the other side were like, it was actually taken about a mile before the end of the downhill. We regenerated energy at an average of 125 watt hours per mile with the cruise control stuck on 55 mph for the whole downhill ( used no friction brakes ). I tried to go about 55mph on the uphill so the speed of the climb and the descent should be about the same. It was amazing to go 7 miles and watch the real range of the car increase by about 3 miles or so and the estimated range went up by 40ish ( I don’t remember exactly ).
I don’t know the exact length and height of each side of the pass, but at the summit there was a sign that said 6% downgrade for 7 miles, if we assume that it’s symmetric we can do some really rough math. We averaged 569 Wh/mi consumed on the way up. We averaged 125 Wh/mi generated on the way down. If you add those up you get 444 Wh/mile total used for 14 miles. The 80.3 mile trip averaged 282 Wh/mile. If we remove a 14 mile section of 444 Wh/mile, the other 66.3 miles of the trip calculates out to 247 Wh/mile. Then the uphill was 322 more than the average ( 569 – 247 = 322 ) and the downhill was 372 less than the average ( 247 – -125 = 372 )
If I had known what was coming I would have reset the trip meter at the start of the climb, the summit, and the end of the descent, but I didn’t, and I wasn’t about to go back and do it again. We didn’t even think to try to record the data until we were almost at the summit so that’s the best we can do.
We rolled into Grant’s Pass after going 80.3 miles, using 22.65 kWhr for an average of 282 Wh/mile – with 42 miles of ideal range left ( in standard mode, which means about 65 in range mode, for about 65 / 250ths of battery ).
We set the car up to charge, and I set it at 32 amps, and went to eat dinner. There were a lot of choices within walking distance, and we had a really nice relaxed meal. After dinner, I checked on the car, and since I knew it was going to have another 8 hours or so to charge at minimum, I turned it down to 24 amps. The hotel was right next to the RV park, so not a lot of walking was required.
