Texas Instruments develops high-cell-count EIS-enabled intelligent battery monitor. By Zahra Awan June 10, 2026 3 Mins Read Texas Instruments (TI) has launched a high-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 and energy storage system applications. The BQ79826Z-Q1 battery monitor enhances safety and extends battery life by detecting potential failures from within battery cells. The single chip tracks up to 44% more channels than previous generations. With this increase, the device significantly decreases the number of components required in a battery pack, reducing system complexity and cost without compromising reliability "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...
