Texas Instruments (TI) has launched an industry-leading battery monitoring device with a single chip that can monitor the maximum number of battery cells and integrates an electrochemical impedance spectroscopy (EIS) computing engine. This device endows battery monitoring solutions for electric vehicles (EVs) and energy storage systems (ESSs) with predictive intelligence, complete data collection capabilities, and real-time fault diagnosis capabilities.

The BQ79826Z-Q1 battery monitoring chip can predict potential faults deep within the battery cells, enhancing the safety of the battery system and extending the lifespan of the battery pack. 

This single-chip device achieves the highest capacity of cell monitoring channels among products of the same category. The number of cell channels it can monitor has increased by 44% compared to the previous generation product. 

Thanks to the significant increase in the number of channels, this device can significantly reduce the usage of peripheral components around the battery pack. Without sacrificing the system's reliability, it lowers the complexity of the overall design and the total cost of the hardware. 

Liu Wenjia, Vice President and General Manager of the Battery Management System (BMS) Division of Texas Instruments, stated: "The trend of transportation electrification and the rapid expansion of the energy storage industry are constantly reshaping the requirements for battery performance indicators in the industry. As a leading manufacturer in the field of battery management technology, Texas Instruments has unique advantages to address these industry challenges. Our high-stringency battery monitoring chip with an embedded EIS engine is equivalent to installing an 'infrared camera' inside the battery cells, capable of outputting detailed chemical state data of the cells, enabling the system software to make precise and real-time decisions regarding the safety status and operational performance of the battery pack, and helping engineers overcome the most critical technical challenges in the field of battery management."
