Frequently Asked Questions:
Question: What is EIS?
Answer: EIS is the abbreviation for electrochemical impedance spectroscopy. EIS is a swept frequency technique for evaluating the internal electrochemical and electrical properties of a battery under test. It is a method to characterize the impedance of a battery by stimulating it with a small amplitude AC signal.
Question: What is EIS used for?
Answer: The BA8100 brings EIS technology from the research laboratory to the industrial market. The device performs galvanostatic EIS on individual cells up to a voltage of 80 V, making it ideal for characterizing and testing energy storage systems. Sweeping the stimulus AC signal provides a graphical representation of the battery response. The instrument is used for incoming inspection, battery second use (B2U), battery stack service and manufacturing.
