Description
The Hioki BT4560 Battery Impedance Meter is an advanced EIS (Electrochemical Impedance Spectroscopy) tester designed for high-capacity batteries used in electric vehicles (EVs) and energy storage systems (ESSs). Combining speed, precision, and reliability, the BT4560 enables engineers and researchers to assess battery quality, internal resistance, and electrochemical characteristics with confidence.
High-Precision EIS Measurement
The BT4560 allows users to set measurement frequencies from 0.01 Hz to 1.05 kHz, providing flexibility to evaluate charge transfer resistance, electrolyte resistance, and diffusion resistance accurately. Low frequencies are ideal for detecting diffusion and charge transfer phenomena, while high frequencies are suited for measuring electrolyte and welding resistance.
Real-Time Nyquist Plotting
This meter simplifies complex battery analysis by instantly creating Nyquist (Cole-Cole) plots via bundled application software. Users can visualize battery characteristics in real time, streamlining R&D testing and accelerating troubleshooting. Additionally, data can be exported to equivalent circuit analysis tools for deeper evaluation of battery defects.
Stable and Reliable Measurements
Specialized four-terminal pair probes minimize magnetic flux and environmental noise, ensuring stable, reproducible measurements even for batteries with very low impedance (<1 mΩ). This guarantees reliable results across lab and production environments.
Production-Ready and Expandable
Equipped with a LAN interface, the BT4560 supports multi-channel testing, making it ideal for integration into automated inspection systems on production lines. Its high-precision measurements, combined with stable long-term operation, ensure efficient, high-throughput testing without sacrificing accuracy.
Engineered for both research laboratories and industrial facilities, the Hioki BT4560 delivers a comprehensive solution for battery quality control, R&D, and high-capacity battery evaluation.
