Texas Instruments develops high-cell-count EIS-enabled intelligent battery monitor - Automotive Testing Technology International

Texas Instruments (TI) has introduced the BQ79826Z-Q1, a high-channel-count battery monitor with integrated electrochemical impedance spectroscopy (EIS) technology, aimed at enhancing battery monitori... Read original →

TI’s integration of EIS into a high-channel-count monitor isn’t just a spec bump—it collapses BMS architecture layers and forces analog front-end suppliers to accelerate sub-3nm BCD processes. With the EU’s Battery Regulation 2023/1542 mandating traceable state-of-health by 2027, TI’s solution preempts compliance costs for automakers. Competitors like ADI and NXP may abandon generic AFE strategies, instead co-developing algorithmic stacks with CATL or BYD. Within 18 months, in-situ impedance-capable chips will become standard in premium EVs, shifting BMS from reactive protection to predictive analytics—and potentially spawning a standalone battery digital twin services market.
