Texas Instruments introduced the BQ79731-Q1, a battery monitoring chip designed to improve safety in electric vehicle and energy storage systems through integrated electrochemical impedance spectroscopy (EIS). The single-chip solution can monitor up to 26 individual battery cells, performing real-time impedance analysis to detect changes in internal resistance and capacitance that may indicate degradation or developing faults.
The device supports daisy-chain communication for high-voltage battery packs and is designed to integrate with existing battery management systems using TI reference designs. By embedding EIS directly into the monitor, the chip provides deeper insight into battery health than traditional voltage-only monitoring, helping identify potential issues before they escalate into thermal runaway events.
For manufacturers and operators, the technology supports predictive maintenance, improved reliability and lower warranty costs. The launch reflects growing demand for advanced battery diagnostics as EV and grid-scale storage deployments continue to expand.
