3 Description

The BQ79826Z-Q1 is a new high-cell count 26S stackable battery monitor that includes integrated electrochemical impedance spectroscopy (EIS) engine. The EIS engine provides a new way to detect impedance changes in the cell that allows for monitoring of aging, temperature, SoC, thermal runaway and many other cell parameters. In addition, the device incorporates an intelligent sensor controller to enable easier and more reliable sensor measurements.
