EA BIM 20005 — 20-channel battery impedance meter (EIS)
Country: Germany · Model: BIM 20005
The BIM 20005 impedance meter measures the impedance of lithium-ion cells by electrochemical impedance spectroscopy (EIS) on 20 channels at once. The frequency range is 1 mHz – 10 kHz and impedance is 0,1–100 mΩ with an |Z| accuracy better than 1 %. The device is built into battery test systems.

Description
Excitation is multi-frequency, so the spectrum is recorded faster than with sequential frequency scanning. The AC excitation current reaches 10 A (peak-to-peak), and the DC component of 0–5 V / ±1 A makes it possible to measure a cell under charge or discharge. Twenty PT100 temperature inputs are added to the 20 measuring channels, so the impedance of each cell is tied to its temperature. Data is exchanged with the control system via USB or CAN. The device consumes less than 60 W from a 100–230 V AC grid and takes up 3U in a 19″ rack.
How to choose
The main limitation of BIM 20005 is the 0–5 V voltage, so the device works with individual cells, not with modules. Twenty channels are convenient for incoming inspection of cell batches and sorting them by condition. For cycling the cells themselves with large currents it is complemented by the 18-channel cycler BCTS 20010-600-18, and modules are tested on BMTS 20200-840-2.
