BK Precision BA8100 [BA8100] EIS Battery Analyzer, 0.5 V to 80 V

The BK Precision BA8100 EIS Battery Analyzer, 0.5V to 80V uses EIS (Electrochemical Impedance Spectroscopy), a swept frequency technique for evaluating the internal electrochemical and electrical properties of a battery under test. EIS is a method to characterize the impedance of a battery by stimulating it with a small amplitude AC signal.

This instrument performs galvanostatic EIS on individual cells or strings not exceeding 80V, making it ideal for energy storage and conversion systems. Sweeping the stimulus AC signal provides a graphical plot of the battery's response revealing a composite view of the battery's internal properties. Select specific frequencies to evaluate interconnections, deterioration of plates, electrodes, or electrolyte.

PC Software
Enhance the capabilities of the BK Precision BA8100 with the provided application software. Facilitate measurement setup with automatic sample rates and input gain control. Acquire and log data across linear, logarithmic or custom frequency sweeps at different current amplitude levels. Analyze data using the provided Nyquist and Bode plot tools or through user's choice of software. Additional features include a meter display, voltage plot and current plot for verifying the latest measurements.

Performance Verification
Knowing your instrument is working at its best is critical to battery testing. The BK Precision BA8100 includes the TLC81 Self-Test Fixture that is used for verifying your instrument's performance and ensuring measurement accuracy. Consisting of a low inductive 5 mΩ precision resistor, the TLC81 and BA8100 require an external power supply during the verification and compensation process.

Test Lead Compensation
The openings on each side of the TLC81 are designed to compensate for the resistance introduced by the test leads.
