Description

Electrochemical Impedance Spectroscopy (EIS) Battery Analyser from B&K Precision.

The BA8100 is designed for diagnosing single battery cells or battery stacks up to 80 V. These instruments accurately measure impedance and phase. Auxiliary measurements include voltage, current, capacitance, inductance, as well as 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.
