Edit - 25 August 2011, Version 6a

If you decide to use this chart, you can print it out, and just cut off the Battery % column on the left. Lot's of changes based on user input that you can read through the thread.

If you would like a PDF or the original Excel file, just PM me.

Woah, great improvement. Love the addition of both elevation and temperature rules of thumb at the bottom of the chart.

This is very cool. I have a stupid question: Is the reason the battery % and distance numbers are between Fuel Bar lines because its an average between those two numbers?

For example, if you drive 40mph and you have 10 fuel bars, you will get between 88-96 miles (on a level road, no HVAC, etc, etc.)?

Those little numbers to the right of each range column are not an average. It's the distance you can travel in that fuel bar, in this case, 8 miles for that #10 fuel bar at 40mph (or 5.2miles/kWh for around town driving).

If you're driving down the highway at 40mph, and happen to look down and see the number 11 fuel bar disappear, leaving 10 left, you could drive 96 more miles under the same conditions. When you drive 8 more miles, the number 10 bar will disappear, and you'll have 88 miles left.

Those of us with SOC meters can actually see, for example, 81.1% battery, and see that we have 92 miles left, and fuel bar 10 will still be lighted.

One quirk, of many, is that if you were looking at the #10 fuel bar, and pulled into the local gas station at 81.1% battery for a window wash and to see how much gasoline sells for these days, when you restart your car, you most probably will not see that #10 bar. The battery level is exactly the same as when you turned off the car (again, we can still see that 81.1% with an SOC meter), but since that bar isn't completely full, it won't light up again.

So, you'll be looking at 9 bars as you continue your 40mph drive in level Kansas country roads (with no wind), but you'll get 12 miles for that #9 bar instead of 8 miles (8 miles for bar #9, and 4 miles of the non-lighted bar #10).

Is that clear enough?
Thanks,

How did you come up with the elevation change information? I ask because I have a 1,400 elevation change each way every day and it does not track with what I typically see...

Also I notice a typo: "console" is misspelled.

Mostly SWAG. What do you get? I haven't done any hills with the SOC meter, but we have plenty to try.

Using one additional bar per thousand feet climbed seems to be about right, at least based on my observations. Keep in mind that this is in addition to whatever energy might be required to cover the distance on the flats.

Going to work, I have a 1400' elevation change downhill and about a 23 mile trip. It is mostly freeway with an average speed of probably around 45mph (high of 68 and low of stop and go). I typically use barely 2 bars going to work and 6 bars coming back. I'll have to play with the math - perhaps your ROT is about right considering the coarse granularity of the bars... When I get one of the SOCs I'll be able to tell with much more accuracy.
