How to brake most efficiently
With the help of my little onboard computer, I ran some data collection
to determine how to brake to generate the most energy. I went from ~40 mph
to ~5mph and recorded the generated current / voltage under different but even
braking styles. Using the collected data, the appropriate integrals were calculated
The below graph summarizes my measurements.
As it can be seen from the graph, the most efficient braking happens
around brake pedal value 17 ( as available on the CAN ), which translates
to about 22 seconds from 45mph to 5mph if you don't have access to the
raw data. It is a gentle, but firm push on the brake pedal.
Here is the spreadsheet from which the graph was derived from.
