Ok, let's talk about this at the next OC meet this Saturday. I need a better timing method... maybe lap timers like we use in racing.garygid wrote: I have supplied LEAF Logging Systems to several

She is my hero! not only has she become invaluable in your quest to reveal the true meaning of the LEAF, she also puts up with you so we dont have too!!TonyWilliams wrote:She was the timer.Boomer23 wrote:Is the "daughter in back seat" condition reproducible?
I too would like to see regen data from these great tests. Hopefully we won't have to wait for Ingineer.Herm wrote:If we had an accurate way to measure energy going in-out* of the battery you could find out how efficient regen is.
*that was a hint for Enginier.. a module with a good coulomb counter in it.
This is very good. I am sure the current measurement is plenty fine for our purposes. When I suggested some time ago adding some integration functionality for those of us without a data-logging Windows laptop, I seem to recall that was not practical because the software environment of your meter's processor did not provide a decent time-base with interrupt delays, etc. Is that still true ? In data-logger mode you have the time in your lap-top and even more accurate time from your GPS dongle.garygid wrote:With the simple single-channel logging that the GID-Meter does,

Voltage and Current, and times down to (probably) a few
milliseconds. That gives us Power, and ultimately, Energy.
True, we do not know how good the Current measurement is,
but the voltage has been verified, I believe.
