US-based check and measurement agency Tektronix has launched its EA-BIM 20005 Battery Impedance Meter outfitted with superior multi-sine stimulus know-how, enabling impedance measurements at a number of frequencies concurrently.
The EA-BIM 20005 may carry out sweep measurements, providing flexibility in testing approaches. The meter can check as much as 20 channels with quick multiplexing and has a entrance panel exhibiting 20 channels for electrochemical impedance spectroscopy (EIS) measurements, plus 20 channels for temperature sensors.
It options industry-standard interfaces and a compact design for seamless integration to assist engineers to reinforce accuracy and effectivity in battery testing workflows.
The EA-BIM 20005-10-20 mannequin presents a frequency vary from 1 MHz to 10 kHz, offering extra data than fastened 1 kHz programs. This enables for a complete evaluation of battery cell conduct beneath numerous circumstances, in line with the corporate. The system’s AC stimulus can attain as much as 10 A (peak-peak), making it appropriate for testing cylindrical, pouch and prismatic cells.
Each EIS channel is accompanied by a high-precision 4-wire PT100 temperature measurement channel. This integration permits for simultaneous monitoring of impedance and cell temperature, offering a extra holistic view of battery efficiency and well being.
The meter is designed to work seamlessly with cycle testing programs. Its built-in energy stage permits the charging and discharging of cells with a present of +/- 1 A. For increased currents, it can be used together with high-power battery check programs such because the EA-BCTS. The system can all the time stay linked, recognizing the influences of cabling and energy phases of battery testers, thus eliminating the necessity to disconnect and reconnect cables for every check.
“By offering quick, correct insights into Li-Ion battery cell high quality by way of high-throughput battery impedance testing, this method enhances the effectivity and reliability of battery testing workflows,” Tektronix stated.
