Achieve Long Service Life Battery Modules by Measuring Reaction Resistance

BT4560 Battery Impedance Meter Introductory Video

Hioki benchtop battery testers support simultaneous high-speed measurement in the ever-expanding production lines of increasingly larger lithium-ion low resistance batteries. The BT4560 battery impedance tester measures the impedance of lithium-ion batteries using the low-frequency AC-IR measurement method without charging and discharging the battery, substantially reducing the time needed to inspect the internal resistance of battery cells.

Key Features

  • Low-frequency AC-IR measurement (*1): Measure the reaction resistance of a battery
  • Extremely reliable measurements for low-impedance batteries (*2)
  • Circuit configuration highly tolerant of contact and wire resistance to provide stable measurements
  • Voltage measurement function equivalent to 6-digit DMM (± 0.0035% rdg.)
  • *1:The BT4560 ensures battery cell quality by measuring internal impedance at a low frequency of 1 Hz or below.
  • *2:The BT4560 uses a testing current of 1.5 A at the 3mΩ range, which improves the S/N ratio.

Manage electrode reaction resistance, electrolyte resistance, and welding resistance to Improve the quality of battery cell inspections

- Set your own measurement frequency between 100 mHz and 1.05 kHz
- Use low frequencies to measure electrode reaction resistance
- Use high frequencies to measure electrolyte resistance and welding resistance
- Create Cole-Cole plots (with bundled application program)
- Use equivalent circuit analytic software to analyze internal battery defects

Create Cole-Cole plots instantly

Cole-Cole plots of Lithium-Ion batteries can provide invaluable insights into the battery chemistry and aid in research and development. This type of analysis has often been complicated, time-consuming, and expensive. Using Hioki's BT4560 Battery Impedance Analyzer connected to your PC, you can perform a frequency sweep quickly and easily, with the results plotted in real-time.

Measure very low impedances of 1mΩ or less

Some high-capacity Li-ion batteries have an internal impedance less than 1 mΩ.
The BT4560 is designed to measure very low impedances of 1mΩ or less with high stability and reproducibility.

Dedicated probes for four-terminal pair measurement reduce the magnetic flux generated

Probes with a four-terminal pair structure provide very stable measurement that is less affected by environmental noise or cabling.
