3 Description

The BQ79826Z-Q1 is a high-cell count 26S stackable battery monitor with an 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 internal cell parameters. The device integrates dedicated ADCs per channel with cell balancing up to 300mA peak. The peripheral features enable an intelligent sensor controller for temperature, pressure, gas and other sensors to meet demanding safety requirements.
