Graphing the cycle

The new code has the ability to log both the charge and the discharge, and with the automatic discharger, we can do automatic cycles to fully exercise the pack right on the bench or in the car. The graphs show the log from cycling the prius pack below. Notice how we start sampling the discharge at 6 second intervals instead of minute intervals so we can more accurately and quickly detect a cell drop out. seems to work well. The graph also shows how the plateau detection with a 10 minute sample time does not do as good of a job as the 30 second sample timer. Also the graph shows how one can set the cutback higher to speed the charging process, but better not go so high that the topping never starts. A good reason to graph the charge so you can better determine the best cutback for your pack. I cut the topping short on the final charge as it was 2AM and I needed to go to bed. Will run another cycle
