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

About this update from Texas Instruments Incorporated

 Engineers can build safer, higher-performing electric vehicles and energy storage systems with TI's new BQ79826Z-Q1 battery monitorNews highlights:The industry's first 26-cells-in-series channel battery monitor delivers best-in-class sensing accuracy, reducing system costs by supporting more cells per device than competing solutions.Integrated smart EIS engine enables early warning of thermal runaway from inside battery cells, helping ensure safety in EVs and ESSs.Designed to help engineers create safer, higher-performing automotive and industrial applications, the BQ79826Z-Q1 is the latest addition to TI's portfolio of BMS devices.DALLAS, June 9, 2026 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today 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. 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."For more information, see ti.com/BQ79826Z-Q1.Delivering safety and performance with EIS tech...
