The EA-BIM 20005-10-20 model offers broad-frequency EIS capabilities, with a frequency range from 1 mHz to 10 kHz. This wide range provides significantly more information than fixed 1 kHz systems, allowing for a comprehensive analysis of battery cell behavior under various conditions. The system's AC stimulus can reach up to 10A (peak-peak), making it suitable for testing cylindrical, pouch, and prismatic cells.

Every EIS channel in the EA-BIM 20005 is accompanied by a high-precision 4-wire PT100 temperature measurement channel. This integration allows for simultaneous tracking of impedance and cell temperature, providing a more holistic view of battery performance and health.

The EA-BIM 20005 is designed to work seamlessly with cycle testing systems. Its integrated power stage enables the charging and discharging of cells with a current of +/- 1A. For higher currents it can also be used in concert with high-power battery test systems such as the EA-BCTS. Additionally, the system can always remain connected, recognizing the influences of cabling and power stages of battery testers, thus eliminating the need to disconnect/reconnect cables for each test.
