AI Customer ServiceFigure 1’s voltmeter measures a single cell battery. Beyond the obvious, the arrangement works because there are no voltages in the measurement path other than the measur-and. The ground referred voltmeter only encounters the voltage to be measured. Figure 2’s “stack” of series connected cells is more complex and presents problems.
Voltmeter Measuring Ground Referred Single Cell is Not Subjected to Common Mode Voltage volts in a large series connected battery stack such as is used in an automobile. Such high voltage operation is beyond the voltage breakdown capabilities of most prac-tical semiconductor components, particularly if accurate measurement is required.
Cell voltage measurements are reported in units of millivolts, while voltages measured for the stack, PACK pin and LD pin are reported in units of centivolts (10 mV) or millivolts, as set in Settings > Configuration > DA Configuration in device data memory. Raw ADC readings are provided in units of counts.

Automobiles, aircraft, marine vehicles, uninterruptible power supplies and telecom hardware represent areas utilizing series connected battery stacks. These stacks of individual cells may contain many units, reaching po-tentials of hundreds of volts. In such systems it is often desirable to accurately determine each individual cell’s voltage.
