100% range test [follow along]

[BarryGoyette]

I've tried this once or twice and decided I wanted to try it again. I charged to 100% last night and will see how far I can drive until I get near/under 20%. The weather is warm this week, low 80's for the high, low 50's for the lows. Wind is minimal and shouldn't play a big factor. Doesn't get much more ideal.

Here's my starting off stats, I'll try to capture each time I stop somewhere and screenshot the internal stats as often as I can. I've noticed the coolant temp sensor seems to track outside temp pretty well. I'll post the rest of today after I get kiddos to bed.

FWIW. Starting from 100%, on an unseasonably warm 70° California day. I did an 80 mile round trip on Sunday, all freeway/highway. Returned with 250 miles range. Speed was 55-70.

Twas a first.

That's impressive for freeway, was there a lot of traffic to help drafting? I did find that 60mph avg netted me very good mileage with moderate traffic. I try to stay 60-65mph on my commute, but I'm only on the freeway for 4 or 5 miles. so I don't think it impacts me too much.

Not really, although the country highway that made up half the trip is curvy enough to keep my speeds low in the range during that section. I think the message is that if you drive in similar conditions to the EPA testing, that you’ll get similar range.

15% used today. Made one extra trip about a mile that I didn't log, was just driving to a lab. Adding an extra screen grab for starting, garage is not heated... its just really warm this week and it gets full morning sun. Means I don't need to use climate. I am using AC on auto 1, 72F on the way home.

Total of 115 miles, using 29% SOC or 38 kWh yielding 3.02 MPK, potential maximum range 396 miles

Day 3, 17% used. Had the weird *vampire drain* and dropped 2% after starting up to leave work. It's still in the ball park of what I use but annoying. I wish I knew why it's dropping. The temp increased so I think I can rule that out now. Part of it I think was being on the edge of 64 (I think it showed 65 on the dash). Either way here's the screenshots.

You can see a couple kWh lower energy after sitting in the parking lot all day. The displayed SOC didn't update until I started driving, but the actual shows that about 1.2 kWh was lost. I haven't seen this ( or at least haven't noticed it ) until the past month or so. I sometimes drop 3% displayed. I didn't notice this at the higher SOC, will be interesting to see if it happens at the lower. Maybe it's a quirk of the middle part of the battery? I used to charge to 85% but did start lowering that to 70% for min/maxing battery life.

Watching .... glad your documenting this, I wish I understood more....

Have you been plotting the results, I wonder if these vampire drops can be correlated to HVB voltages stabilizing after a rest ... I believe plot for the discharging HVB is not a straight line, so perhaps when the pack voltage stabilizes and settles the reported SOC may need to change without apparent reason??

Thank you all for doing these tests. Good info. I have a late 2022 build of a 2023 base XLT, standard range, max trailer tow. I tow a 7000# trailer locally, use the truck for grocery store runs, etc.I usually L1 charge at home, but can do L2 when needed. Zero range anxiety, except for the one time a storm hit and I lost power, then needed to tow the next morning. I always charge L1 or L2 whenever I can and it is all good.

Total of 168.9 miles, using 46% SOC or 60.3 kWh yielding 2.8 MPK, potential maximum range 367 miles, but likely less as yesterday's efficiency was closer to normal EPA loop value of 2.42 MPK, that said, 340 miles max range.

I think the drop in efficiency yesterday was from the weird midday shenanigans. The past 3800 miles on Trip 1 show 2.7 average. I suspect that will be the end average for this test as well.

@Grumpy2 That's a good thought about the charge curve. I haven't been keeping super good records until recently. If I find the time, I'll start entering them in a spreadsheet to generate a plot and see if there are any trends. Since temperature and other factors can influence the data, I'll try to note that as well.
