C8051F912-DK
The wakeup frequency box calculates the period of a single iteration through the four power modes and displays
the system wake up frequency. This is typically the "sample rate" in low power analog sensors.
Once the battery type and discharge profile is specified, the user can click the "Simulate" button to start a new
simulation. The simulation engine calculates the estimated battery life when using one single-cell battery, two
single-cell batteries in series, and two single-cell batteries in parallel. Figure 5 shows the simulation output window.
Figure 5. Battery Life Estimator Utility Simulation Results Form
The primary outputs of the Battery Life Estimator are an estimated system operating time and a simulated graph of
battery voltage vs. time. Additional outputs include estimated battery capacity, average current, self-discharge
current, and the ability to export graph data to a comma delimited text file for plotting in an external graphing
application.
