Hioki BT4560 Battery Impedance Meter

The BT-4560 can make EIS* measurements quickly and easily in applications ranging from R&D to manufacturing. It delivers high-precision measurement capability for quality control of high-capacity batteries and can be expanded into an evaluation system for efficient measurement of multiple batteries.

• Electrochemical Impedance Spectroscopy (EIS) is a type of testing that measures a battery's impedance across a broad frequency range using small AC signals. The technique, which yields detailed insights into characteristics such as a battery’s internal resistance and electrode reactions, aids in understanding battery behavior and performance, making it useful for R&D and quality control applications.

Traditionally, the internal resistance of battery cells is measured by pre-charging the battery, then passing large currents and measuring the voltage drop (DC-IR measurement). Pre-charging the battery, however, usually takes several minutes to several tens of minutes. The BT4560 eliminates the need for charging or discharging by measuring the internal impedance at a low frequency of 1 Hz or below (AC-IR measurement), enabling a significant reduction in the time required for measuring battery cells.
