Texas Instruments develops high-cell-count EIS-enabled intelligent battery monitor - Automotive Powertrain 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 compresses the BMS stack, forcing upstream MCU vendors to embed deeper functional safety capabilities. With the EU’s battery passport rules looming, TI’s ASIL D-compliant solution slashes compliance overhead for automakers while marginalizing Chinese Tier-2 BMS firms reliant on software workarounds for measurement inaccuracies. Competitors like ADI and NXP may respond with accelerated M&A or EIS IP licensing to retain design wins. Within 18 months, EIS-enabled AFEs will become mandatory for premium EV platforms, shifting the global BMS supply chain toward a ‘highly integrated + diagnostic-native’ paradigm—effectively excluding vendors lacking electrochemical modeling expertise.
