Texas Instruments
Texas Instruments (TI) (Dallas, TX) introduced the BQ79826Z-Q1 for electric vehicles and energy storage systems (ESS). The BQ79826Z-Q1 is designed for high-cell-count battery monitoring with predictive intelligence and real-time diagnostics and can be used in automotive battery management systems (BMS), energy storage and artificial intelligence data center power banks.
The BQ79826Z-Q1 provides a high-accuracy voltage tracking and internal chemical-state diagnostic solution for multi-cell high-voltage battery packs using an integrated electrochemical impedance spectroscopy (EIS) engine standard.
Features:
- Tracks up to 26 cells per device
- Provides early warnings of critical failures like thermal runaway
- Achieves precise cell voltage measurement accuracy of less than 2mV across full operational temperature envelope spanning from –40°C to +125°C
- Delivers EIS measurement velocity that is five times faster than previous market solutions
- Connects seamlessly with BQ79881-Q1 pack monitor to establish flexible chipset that scales across diverse module sizes, mechanical layouts and cell chemistries.
