BT-1000L Lithium-Ion Cell Battery Tester
Model # BT-1000L
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 meter 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.
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.
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.
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.
