I would like to measure how much regen energy I'm getting for my commute. I drive 33 miles one-way..... charge at work and return over the EXACT SAME route. My electric range can vary by as much as 10 miles (same weather temp).
I suspect the difference is due to traffic patterns and regen. The morning drive is at 9AM and the return is at 2PM. It is a lot slower in the morning with more stop-and-go traffic (driving in L).
I have a DASHDAQ but don't see any counter for regen energy. Can anyone think of an indirect way to calculate the regen energy on a drive??? I can see AMP HOURS.....which generally is used up during driving but is added to during regen/braking. So, I might get a total at the end of 21 amp hours but that does not really tell me anything about the regen contribution.
