Main Screen - Graph

The graphing tool is a powerful dynamic display that plots the collected data in line chart form. Here you can see line plots for: Voltage (Yellow), Current (blue), Temperature (red) and Temperature change dT/dt (orange).

In the above example, for the first 20 minutes you can see the voltage dropping as the battery discharges at 1400 mA (2C rate) . The battery temperature is rising during this discharge and near the end of the discharge the rate of temperature rise peaks.

For the charge cycle up to the 80 minute mark you can see the voltage rise as the battery charges at a constant 700 mA (1C rate). The battery is still cooling from the preceding discharge, except at the very end of the charge cycle where temperature rises dramatically once the battery is fully charged.

 

The battery then enters the discharge of the 2nd cycle where the current once again is 1400 mA and temperature continues to rise. During both discharge cycles notice the cycle ends when the battery voltage drops to 10 volts.

Presently the battery is at the 2 hour and 15 minute mark in the final charge of this 2 cycle session.

The controls on the top and right sides of the graph are used to zoom into and pan left and right. This is used to view an area of interest in more detail.
