BATTERY IMPEDANCE METER
BT4560
Achieve Long Service Life Battery Modules by Measuring Reaction Resistance
Overview
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* : Measure the reaction resistance of a battery
- *The BT4560 ensures battery cell quality by measuring internal impedance at a low frequency of 1 Hz or below
• - Extremely reliable measurements for low-impedance batteries
- *The BT4560 uses a testing current of 1.5 A at the 3mΩ 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.)
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
