Description

The Keysight BT2152A Self-Discharge Analyzer directly measures self-discharge current on large numbers of Li-Ion cells. The analyzer provides a revolutionary reduction in the time required to discern good vs. bad cell self-discharge performance. This drives dramatic reductions in Work-in-Process inventory, working capital costs, and facility costs for cell manufacturers.

The Self-Discharge Analyzer accurately measures cell self-discharge current and cell voltage. Depending on the characteristics of the cells, measurements are directly made in minutes or hours instead of taking weeks or months using open-circuit cell voltage measurements to indicate which cells are good vs. bad.

The Self-Discharge Analyzer quickly measures self-discharge current using a potentiostatic measurement method with the characteristics needed to accurately make the current measurement:

  • Minimum disturbance of the cell
    • The voltage applied to the cell is quickly matched to the actual cell voltage. This minimizes any new charge or discharge and thus limits any new RC settling to a minimum.
    • The voltage applied to the cell is very stable (± 10 μVpk) to minimize continuing charge redistribution current noise on the self-discharge current measurement.
  • Accurately measures low-level self-discharge currents to ±(0.33% + 1μA)
