A new battery gauge with Dynamic Z-Track™ algorithm supports precise battery monitoring.
Texas Instruments (TI) has introduced a new battery gauge with Dynamic Z-Track™ algorithm that enables precise battery monitoring in a variety of applications, including laptops and e-bikes, and extends the operating time of electronic devices by up to 30%.
TI Korea (CEO Park Joong-seo) officially announced the launch of the single-chip battery fuel gauges 'BQ41Z90' and 'BQ41Z50' with the Dynamic Z-Track™ algorithm on the 30th.
These products feature high-precision predictive modeling algorithms that can accurately measure state of charge (SOC) and state of health (SOH) with an error of less than 1%, extending battery operating time by up to 30%.
It supports real-time battery monitoring in various fields, including laptops, electric bicycles, and medical devices, and can simultaneously improve energy efficiency and device lifespan.
TI's BQ41Z90 and BQ41Z50 enable accurate battery capacity measurement even under unpredictable, dynamic load environments, helping designers avoid overdesigning batteries and build efficient systems.
Yevgen Barsukov, Senior Research Scientist at TI and Head of BMS Algorithms “Dynamic Z-Track technology can accurately predict the battery’s condition even in rapidly changing usage environments, such as with AI-based applications,” the doctor emphasized.
The BQ41Z90 is the industry's first highly integrated fuel gauge solution supporting 3 to 16 serial cells. It integrates monitoring and protection functions into a single chip, reducing board space by 25% compared to previous models. The BQ41Z50, with its compact configuration for 2 to 4 cells, is ideal for small device designs.
These technological advancements go beyond traditional reactive battery monitoring, offering predictive models that deliver a range of benefits, including reliable operation, improved safety, and extended battery life.
The BQ41Z90 and BQ41Z50 are available for pre-production quantities now on TI's official website (ti.com), along with evaluation modules (EVMs), reference designs, and simulation materials for designers.
