Battery Life, 50A load discharge test method/results

[Al Skierkiewicz]

Dale,
I believe you can upload ppt files to the white paper area. You numbers are consistent with our research from several years ago. The first year custom circuits were part of the rules we built a current monitor that had several channels of data recording. That data was ported out to the dashboard at the OI and the battery voltage monitor on the RC also appears at the dashboard. By interfacing the data output, to a palm we were able to display and log conditions we thought would be dangerous to RC life support. (prior to backup battery introduction) It was easy to see the correlation between current draw and battery terminal voltage. With a portable rig we were able to test robots for other teams during practice or in the pits and it showed a tremendous amount of data, even showing one team that had a failed motor in one of their multi motor drive systems.
