Battery cell voltage is the most fundamental measurement made on the cell. While on the surface measuring voltage seems easy, challenges and accuracy considerations must be understood before your cell voltage measurements can be trustworthy.
This power-management tip introduces the two different circuits for a positive-to-negative voltage conversion and a negative-to-positive voltage conversion.
Zeroing in on the right voltage measurement device is critical to achieving the accuracy and speed of measurement required for your voltage measurement task.
Engineers may struggle with making accurate ripple measurements using an oscilloscope. However, there are many ways for this seemingly simple measurement to go awry
