Figure 5. Battery Life Estimator Discharge Profile Editor
The Discharge Profile Editor allows the user to modify the profile name and description. The four text entry boxes
on the left hand side of the form allow the user to specify the amount of time the system spends in each power
mode. On the right hand side, the user may specify the supply current of the system in each power mode.
Since supply current is typically dependent on supply voltage, the discharge profile editor provides two columns for
supply current. The V2 and V1 voltages at the top of the two columns specify the voltages at which the current
measurements were taken. The Battery Life Estimator creates a linear approximation based on the input data and
is able to feed the simulation engine with an approximate supply current demand for every input voltage.
The minimum system operating voltage input field allows the system operating time to stop increasing when the
simulated battery voltage drops below a certain threshold. This is primarily to allow operating time estimates for
systems that cannot operate down to 1.8 V, which is the voltage of two fully drained single-cell batteries placed in
series.
