Hioki BT4560 - Low Frequency AC-IR Battery HiTester

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.
 

Embed in automated machines and production lines

Measure very low impedance

• 3 mΩ minimum range with high noise suppression
• Accuracy: ±0.4% rdg. ±8 dgt.*
• Minimum resolution: 0.1 μΩ

Compared to the current used by traditional battery testers, 0.1A, the BT4560 uses a current 15 times stronger, 1.5 A, which improves the S/N ratio. Enhanced noise suppression enables the device to provide reliable measurements for low-impedance batteries used for hybrid and plug-in hybrid vehicles.

Measure DC voltage with high accuracy

• Voltage measurement accuracy comparable to high-end testers
• Accuracy: ±0.0035% rdg. ±5 dgt.
• Minimum resolution: 10 μV

The BT4560 can measure the voltage much more accurately than traditional resistance meters(±0.01% rdg. ±3 dgt.). It guarantees highly accurate voltage measurement where greater accuracy than that of previous machines is required.

Circuit configuration highly tolerant of contact resistance

The circuit configuration in the BT4560 is not susceptible to contact and wire resistance, enabling stable measurement. Probe cables of up to 4 m are supported, improving the flexibility of cabling in production lines.

Measure without damaging batteries

The BT4560 employs AC-IR measurement with a small current load, enabling highly reliable measurement without damaging batteries.
