Texas Instruments (TI) unveiled 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. TI is showcasing this innovation at the 2026 Power Conversion, Intelligent Motion Expo and Conference (PCIM), June 9-11, in Nuremberg, Germany.
“The electrification of transportation and the rapid expansion of energy storage are redefining what battery performance must deliver, and as a leader in battery management technology, TI is uniquely positioned to meet that challenge,” said Wenjia Liu, vice president and general manager, battery management systems (BMS) at TI.
“Our high-cell-count battery monitor with a built-in EIS engine helps ‘shine a light’ inside battery cells, delivering rich chemical-state data that enables systems’ software to make informed, real-time decisions on safety and performance of the battery pack, allowing engineers to address the most critical challenges in battery management.”
