BIM1000 Series
Battery Impedance Meter
BIM1000 Series Battery Impedance Meter is a professional grade instrument built for rapid, accurate measurement of battery internal resistance and voltage, tailored especially for high voltage and high power batteries such as those used in electric vehicles. It simultaneously measures both battery voltage and internal resistance using a 1 kHz AC four terminal method, enabling fast and reliable evaluation of battery quality. With support for test voltages up to 300 V (model BIM1030) or 1000 V (model BIM1100), the BIM1000 is ideal for both research & development and production line testing enabling comprehensive, high speed testing of modern rechargeable and power battery packs. Thanks to its compact design, high measurement resolution, and built-in logging / I/O capabilities, it ensures efficient battery evaluation for manufacturers, labs, and QA workflows.
