My spread is a bit wider than that, but my commute is 39 miles each way and I'm not going to drive cold for an hour before getting to work, I'd rather be comfortable and so my miles on EV pay the price.
I don't drive with no heat / AC, I just don't have the climate control effects on this particular graph.
Heating use is a minor factor. The major factor is the electrochemical nature of the battery itself. Batteries move less charge at low temperatures:
This graph was to illustrate temperatures effect on propulsion efficiency, and the lions share of that is temperature effects on battery chemistry, so the graph is taken from propulsion use only, with climate control, and "a-typical days" (rain, traffic slowdown, etc.) factored out. I can make another graph with the climate control factored in.
Hello I think that somewhere after 8o degrees the line starts coming down. Or less efficient after 80 something.
Living in Mississippi I will have plenty of over 80F days to gather data from, I will be updating this graph throughout the year.
MPH and acccel is out of the graph. IF the drive is consistant. Not easy to do. Velocity will effect the graph more then just linearly, its a curve. I have links to the curve for Gen one but have not seen the graph for Gen 2. i would assume the curve is the same just offset from the GEN 1 curve. Of MPH vs Miles/KW.
Non-consistent days (got stuck behind a slow poke, rain, etc.) are factored out. I expect the graph to curve at the upper end as I gather more data as summer arrives. It may curve at the low temperature end as well, but I won't be able to gather that data living in Mississippi
Nice work, but I have to deduct several points for a poorly labeled graph
(no axis labels, incomplete title)
Making graphs in Excel sucks, I am just glad I was able to get the correct data.
I think the graph is self-explanatory. What wasn't there, that interests me, is the model year and the equation for the linear fit. Thanks for sharing the data Fourdoor.
Model year is 2016, I would expect the 2017 to be identical... not sure why it matters since this is posted in the 2nd gen Volt forum I didn't feel the need to say "this is a second gen volt"
As far as the linear fit equation, I clicked on the data field and told Excel to add a linear representation of the data, you would have to ask a microsoft programer how it was done
