HIOKI BT4560 Battery Impedance Meter
The battery impedance meter HIOKI BT4560 is the ideal solution for example for measuring large-capacity Li-ion batteries for EVs. The device covers a frequency range between 0.01 Hz and 1050 Hz. Low frequencies can be used to measure electrode reaction resistance, whereas high frequencies are usefull to measure electrolyte resistance and welding resistance.
- Battery impedance meter.
- Perform EIS (electrochemical impedance spectroscopy) using the free PC software to obtain detailed information on the battery characteristics, essential for battery development.
- Measurement frequency between 0.01 Hz and 1050 Hz.
Use low frequencies to measure electrode reaction resistance.
Use high frequencies to measure electrolyte resistance and welding resistance. - Extremely reliable measurements for low-impedance batteries: The BT4560 uses a testing current of 1.5 A at the 3 mΩ range, which improves the S/N ratio.
- Circuit configuration highly tolerant of contact and wire resistance to provide stable measurements.
- Voltage measurement function equivalent to 6-digit DMM (±0.0035% rdg.)
- Create Cole-Cole plots (with bundled application program).
- Use equivalent circuit analytic software to analyze internal battery defects.
- Communication interfaces LAN/Ethernet, USB, and RS232C.
- MAC address indication on rear panel.

1) In July 2024, HIOKI released an enhanced version of the BT4560. The new version is compatible and offers quick and easy EIS measurements for research and development as well as production. The new standard LAN interface simplifies the integration of test systems. The official designation is still B4560, but BT4560-50 is used internally to distinguish it from the previous version. When ordering, you will of course always receive the latest, new version.
