Nordic Semiconductor Unveils Advanced Battery Health Monitoring for IoT Devices
Nordic Semiconductor, a global leader in low-power wireless connectivity solutions, recently announced its groundbreaking product, the Nordic Fuel Gauge v2.0, during the Embedded World 2026 in Nuremberg, Germany. This latest innovation serves as a vital upgrade to the existing fuel gauge software, specifically designed for their award-winning nPM1300 and nPM1304 Power Management ICs. The Fuel Gauge v2.0 incorporates an array of advanced features, including sophisticated state-of-health (SoH) estimation, adaptive battery modeling, and long-term fleet analytics, which significantly enhance battery management capabilities across various IoT applications with strict power constraints.
One of the standout features of the Fuel Gauge v2.0 is its seamless integration with nRF Cloud, powered by Memfault, eliminating the necessity for a custom cloud infrastructure. This advancement enables effective monitoring and real-time reporting of battery metrics, ensuring manufacturers can track the health and performance of their battery-powered devices effortlessly.
Geir Kjosavik, the Product Director for Power Management ICs at Nordic Semiconductor, highlighted the differences in battery performance between laboratory conditions and real-world applications, stating, "With Fuel Gauge v2.0, we have integrated real-world adaptive intelligence, previously limited to premium consumer electronics, into the IoT ecosystem. This marks a significant milestone for the billions of devices reliant on battery power."
This updated version advances beyond the previous state of charge (SoC) measurement introduced in Fuel Gauge v1.0. By employing a dynamic model that continuously compares the original battery profile with its real-world behavior over time, it yields an accurate estimation of SoH. This feature plays a crucial role in tracking charging cycles, observing long-term degradation trends, and ensuring precision even as the battery ages.
For scenarios where users frequently swap out batteries, Nordic’s algorithm can manage multiple batteries concurrently, keeping tabs on the health status of each pack. Unlike traditional fuel gauge ICs that rely on fixed models or coulomb counting—which can alter over time—the Nordic solution utilizes the nPM1300’s integrated voltage, temperature, and current measurements along with an intelligent host-based algorithm. This design offers system-level precision at a reduced cost while minimizing material complexity, significantly lowering energy consumption during sleep modes and providing substantial savings compared to competitor solutions.
As regulations evolve and introduce mandates for battery replacement preparedness, the SoH capabilities of the Fuel Gauge v2.0 become essential. It assists manufacturers in identifying optimal battery replacement timelines, aligning with right-to-repair initiatives, enhancing product reliability, and driving down warranty costs. For those deploying thousands or millions of battery-powered devices, this newfound visibility transforms into a crucial resource for maintaining reliability and optimizing lifecycle costs.
The integration with nRF Cloud, using Memfault technology, enables a robust solution where devices can automatically relay SoH, SoC, and battery performance metrics. This facilitates hardware design improvements based on real data, empowering engineering and operations teams with the ability to monitor battery health across entire fleets and swiftly identify anomalies.
François Baldassari, the founder of Memfault, asserts the importance of enabling hardware teams to access sophisticated device insights. By connecting Fuel Gauge v2.0 with nRF Cloud, businesses can realize a scalable approach to understanding and enhancing device behavior across fleets.
The Fuel Gauge v2.0 is compatible with any host MCU or wireless system-on-chip, including the nRF54 and nRF91 series, making it accessible for OEMs looking to infuse advanced battery intelligence into a diverse range of IoT applications. Currently in beta testing, the Nordic Fuel Gauge v2.0 is expected to be widely available by the second quarter of 2026, as it garners attention at Embedded World 2026, showcasing real-time battery health reports across various devices powered by adaptive intelligence and integrated with nRF Cloud. Visit Nordic’s booth to witness engaging demonstrations and discussions during the event, taking place from March 10-12, 2026 in Nürnberg.
