TI brings intelligence to battery management systems with industry's highest-cell-count EIS-enabled battery monitor

Texas Instruments introduced the industry's highest-cell-count battery monitor with an integrated electrochemical impedance spectroscopy (EIS) engine, bringing predictive intelligence, comprehensive data and real-time diagnostics to battery monitoring in electric vehicles (EV) and energy storage system (ESS) applications.

The BQ79826Z-Q1 battery monitor enhances safety and extends battery life by detecting potential failures from within battery cells. The single chip delivers the highest-cell-count monitoring in its class, tracking up to 44% more channels than previous generations. With this increase in channels, the device significantly decreases the number of components required in a battery pack, reducing system complexity and cost without compromising reliability.

Just as an electrocardiogram (EKG) monitors the heart, EIS monitors a battery. It delivers continuous, real-time insight that reveals the battery's health and warns of issues before they become critical. Integrated EIS technology enables the BQ79826Z-Q1 to detect fault conditions earlier – from inside the cells – helping maintain safety and notifying passengers of potential vehicle hazards such as thermal runaway (more info).
