 Engineers can build safer, higher-performing electric vehicles and energy storage systems with TI’s new BQ79826Z-Q1 battery monitor

News highlights:

The industry’s first 26-cells-in-series channel battery monitor delivers best-in-class sensing accuracy, reducing system costs by supporting more cells per device than competing solutions.Integrated smart EIS engine enables early warning of thermal runaway from inside battery cells, helping ensure safety in EVs and ESSs.Designed to help engineers create safer, higher-performing automotive and industrial applications, the BQ79826Z-Q1 is the latest addition to TI’s portfolio of BMS devices.

DALLAS, June 9, 2026 /PRNewswire/ — Texas Instruments (TI) (Nasdaq: TXN) today introduced the industry’s highest-cell-count battery monitor with an integrated electrochemical impedance spectroscopy (EIS) engine, bringing predictive intelligence, comprehensive data and real-time diagnostics to battery monitoring in electric vehicles (EV) and energy storage system (ESS) applications.

The BQ79826Z-Q1 battery monitor enhances safety and extends battery life by detecting potential failures from within battery cells. The single chip delivers the highest-cell-count monitoring in its class, tracking up to 44% more channels than previous generations. With this increase in channels, the device significantly decreases the number of components required in a battery pack, reducing system complexity and cost without compromising reliability. TI is showcasing this innovation at the 2026 Power Conversion, Intelligent Motion Expo and Conference (PCIM), June 9-11, in Nuremberg, Germany.

“The electrification of transportation and the rapid expansion of energy storage are redefining what battery performance must deliver, and as a leader in battery management technology, TI is uniquely positioned to meet that challenge,” said Wenjia Liu, vice president and general manager, battery management systems (BMS) at TI. “Our high-cell-count battery monitor with a built-in EIS engine helps ‘shine a light’ inside battery cells, delivering rich chemical-state data that enables systems’ software to make informed, real-time decisions on safety and performance of the battery pack, allowing engineers to address the most critical challenges in battery management.”

Delivering safety and performance with EIS technology
Just as an electrocardiogram (EKG) monitors the heart, EIS monitors a battery. It delivers continuous, real-time insight that reveals the battery’s health and warns of issues before they become critical. Integrated EIS technology enables the BQ78926Z-Q1 to detect fault conditions earlier – from inside the cells – helping maintain safety and notifying passengers of potential vehicle hazards such as thermal runaway.

These same benefits extend to ESSs, where reliable battery monitoring is critical to meeting the growing power demands of artificial intelligence data centers. As effective storage solutions become increasingly vital in the grid-to-gate ecosystem, EIS gives engineers real-time visibility into the state of charge and state of health of each battery cell, regardless of system size.

Maximizing efficiency with industry-leading cell count
The performance of an EV or ESS is fundamentally affected by the quality and efficiency of its batteries. The BQ79826Z-Q1 supports up to 26 cells per device, eight more than any competing solution, setting a new industry standard. Fewer monitoring devices means a lower bill of materials, simplified architecture and reduced board space requirements, translating to meaningful cost savings per channel without sacrificing quality or reliability.

When paired with the BQ79881-Q1 pack monitor and optional TI communications bridge, these devices create a powerful chipset that works across different module sizes, battery chemistries and mechanical designs, giving engineers the flexibility to design once and deploy everywhere. This scalability reduces engineering overhead and accelerates time to market for automotive and energy storage designers.

Calculating charge readings with the best-in-class accuracy
With a voltage accuracy of <2mV across a full temperature range of –40°C to +125°C, higher resolution analog-to-digital converters and ultra-low noise, the BQ78926Z-Q1 enables more accurate state-of-charge calculations, directly addressing one of the biggest concerns for EV drivers: range anxiety. Utilizing EIS technology, this device enables more accurate temperature and state-of-charge estimation, helping designers achieve longer battery life and faster charging without compromising battery health. With an EIS measurement time that is five times faster than previous solutions, this device delivers the highest functional safety voltage reading per cell. Compliance with Automotive Safety Integrity Level D and International Organization for Standardization 26262 gives designers a smarter, more efficient path to safer, longer-lasting batteries.

For more information on the BQ79826Z-Q1, see technical article “Enabling the next phase of battery intelligence.”

Innovating what’s next in power at PCIM 2026
Visitors to PCIM can see new products and solutions from TI that are enabling engineers to innovate what’s next in power in Hall 7, Booth No. 652. The new BQ79826Z-Q1 battery monitor will be featured in an EIS-enabled BMS reference design, alongside other innovations such as an 11kW single-stage bidirectional onboard charger, a 50kVA solid-state transformer cell stack with Ethernet and Fast Serial Interface communication and short-circuit protection for silicon carbide power metal-oxide semiconductor field-effect transistors with technology from Flex.

Changhong at IFA 2026: From Going Global to Going Local

Published

By

BERLIN, Sept. 6, 2026 /PRNewswire/ — At IFA 2026, Changhong unveiled a new lineup of AI-powered home appliances spanning TVs, refrigerators, air conditioners and laundry appliances. Centered on real-life scenarios, the company is bringing AI technologies designed to better understand everyday needs into the product experience, highlighting its transition from technological innovation toward more intuitive living experiences. The showcase also signals Changhong’s continued localization efforts.

The concept comes to life across Changhong’s latest AI products. The Q60S Pro TV features the Changhong LeDong AI sports platform, extending the TV beyond a traditional content screen into a space for family fitness and interaction. An AI human-sensing air conditioner can recognize users’ locations and habits and adjust airflow accordingly, while an AI refrigerator uses intelligent sensing to help users take a more proactive approach to food freshness. Rather than adding complexity, Changhong is making everyday life simpler.

This is at the heart of Changhong’s exploration of “seamless technology”—technology that works quietly in the background. The best technology does not always need to be seen; it simply helps people worry less.

A distinctive cultural element is also finding its way into Changhong’s smart product experience. The brand has incorporated the giant panda into AI assistant interactions, bringing greater warmth and approachability to AI-powered TVs and other home appliances. Closely associated with Changhong’s Sichuan heritage, the panda also provides a natural way to bring a recognizable element of Chinese culture into the technology experience.

Skiing offers another bridge to European lifestyles. In recent years, Changhong has continued to strengthen its presence in Europe with CHiQ as an important brand vehicle, building closer connections with local consumers through sports partnerships, including sponsorship of FIS Ski World Cup events in Germany, collaboration with the German Ski Association and its role as an official partner of the FIS Ski Jumping World Cup. More than a sporting platform, skiing allows CHiQ to connect the speed, passion and outdoor spirit of the sport with its product experience, bringing technology closer to the way European consumers live.

Behind these initiatives is a deeper commitment to localization. From product experience and brand expression to sports, culture and local lifestyles, Changhong is creating more diverse touchpoints with the European market. From “going global” to “going local,” the company is moving beyond products and channels toward a deeper integration of its brands, technology and the markets it serves.
