CN0510 User Guide:

Analog Devices Wiki

The CN0510 circuit is an electrochemical impedance spectroscopy (EIS) measurements system for characterizing Lithium Ion and other types of secondary batteries. EIS is a non-destructive perturbation technique used to examine processes occurring inside electrochemical systems. The system measures the impedance of the battery cell over a range of frequencies.

“There are two options for running battery impedance measurements on the EVAl-AD5941BATZ. The first is using SensorPal GUI tool. SensorPal provides an intuitive interface that allows the user to configure and update parameters such as frequency range and view measurement results in Nyquist form without needing to downlaod or use an IDE such as Keil. This option is best for rapid prototyping and measurement verification. The second option is to run the example projects in an IDE such as Keil to modify the low level embedded firmware. This options offers more control over the low level operation of the hardware but requires some knowledge of embedded C development”
