The BA8100 brings Electrochemical Impedance Spectroscopy (EIS) technology out of the research lab and into the industrial market for diagnosing single battery cells or battery stacks up to 80 V. These instruments are designed to accurately measure impedance and phase. Auxiliary measurements include voltage, current, capacitance, inductance, quality factor, and more.

Using the included Frequency Response Analysis software, the BA8100 can perform EIS tests with a frequency range of 50 mHz to 10 kHz. The impedance spectrum can be evaluated through the Nyquist and Bode plot tools to determine effective series resistance (ESR) and track battery health. The included self-test fixture is used to verify the instrument’s performance or compensate for resistance introduced by the test leads.

The BA8100 brings EIS technology out of the research lab and into the industrial market, with a price-performance ratio suited for incoming inspection, battery second use (B2U), battery stack service, and manufacturing.

Enhance the capabilities of the 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 the user’s choice of software. Additional features include a meter display, voltage plot, and current plot for verifying the latest measurements.

Knowing your instrument is working at its best is critical to battery testing. The 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.

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