Eagle Eye BT-1000L [BT1000L] Lithium Ion Battery Tester

Eagle Eye BT-1000L Lithium Ion Battery Tester

Lithium Ion Battery Tester

• All-in-One Compact Unit
• Sample Delay
• Slope Correction Function

The BT-1000L benchtop battery testers supports simultaneous high-speed measurement (10 seconds per cell) in the ever-expanding production lines of increasingly larger lithium-ion low resistance batteries.

The 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. Software is included for viewing measurement data and trending analysis.

Product Advantages

• Low-frequency AC-IR measurement* : Measure the reaction resistance of a battery *The BT-1000L 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 BT-1000L 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.)

Two Types of Test Probes

• Clip Type Probe (pictured) for laminated sheet batteries
• Pin Type Probe for line-embedded applications and various other battery types

Characteristics of the BT-1000L

All-in-One Compact Unit

Correct any offset voltage and gain drift that may be present in the circuit to improve the accuracy of voltage measurement.

Sample Delay

Specify a delay between AC voltage being applied and sampling being started so that measurement can start after the response stabilizes.

Prevent Charging or Discharging when AC Voltage is Applied

To prevent the battery that is being measured from charging or discharging, the battery impedance meter terminates the applied measurement signal when zero is crossed.

Slope Correction Function

If measurement signals drift due to the battery characteristics or the input impedance of measurement instrument, the tester applies correction to the linear drift.

Temperature Measurement

Reaction resistance measured at low frequency is sensitive to temperature. An optional temperature sensor measures the temperature around the battery and associates the results with data, thereby improving the reliability of the measurements
