B&K Precision BA8100 EIS Battery Analyzer

B&K Precision BA8100 EIS Battery Analyzer uses electrochemical impedance spectroscopy (EIS) and offers a maximum input voltage of 80V. EIS is a method to characterize the impedance of a battery by stimulating it with small amplitude AC signals. The BA8100 analyzer features swept stimulus frequency. Sweeping the stimulus AC signal offers a composite view of the battery’s internal properties. This BA8100 EIS Battery Analyzer performs galvanostatic EIS on individual cells or strings not exceeding 80V, making it suitable for energy storage and conversion systems. 

B&K Precision offers the associated TLC81 self-test fixture that is used for verifying the BA8100 analyzer’s performance and ensuring measurement accuracy. Consisting of a low inductive 5mΩ precision resistor, the TLC81 and BA8100 require an external power supply during verification and compensation processes.
