Hioki BT4560 Battery Impedance Meter

Overview

The Hioki BT4560 is a dedicated impedance meter for Li-Ion battery testing and evaluation. It measures battery internal impedance and voltage simultaneously using low-frequency AC excitation (0.1 Hz to 1050 Hz), eliminating the need for charging or discharging before measurement. This approach provides fast, non-destructive testing with excellent repeatability, making it ideal for battery quality control and research applications.

Key Features

• Low-frequency AC-IR measurement capability (0.1 Hz to 1050 Hz)
• Simultaneous measurement of impedance (R, X, Z, θ) and voltage
• High testing current (1.5 Arms at 3 mΩ range) for improved signal-to-noise ratio
• Three impedance measurement ranges: 3.0000 mΩ, 10.0000 mΩ, 100.000 mΩ
• Voltage measurement range: 5.00000 V
• Temperature measurement: -10.0°C to 60.0°C
• Basic accuracy: Z ±0.4% rdg., θ ±0.1°, V ±0.0035% rdg. ±5 dgt.
• Comparator and self-calibration functions
• Interfaces: RS-232C/USB and EXT I/O (switchable NPN/PNP)
