Nordic Semiconductor Unveils New Battery Health Monitoring Technology
Nordic Semiconductor, a leader in low-power wireless communication, recently introduced its latest innovation in battery health monitoring, the Nordic Fuel Gauge v2.0, at the Embedded World 2026 conference. This advanced system significantly upgrades previous technologies, allowing manufacturers to develop smarter and longer-lasting Internet of Things (IoT) devices.
Key Features of Nordic Fuel Gauge v2.0
The Nordic Fuel Gauge v2.0 incorporates sophisticated state-of-health (SoH) estimation and adaptive battery modeling, extending the advanced management capabilities to a wide array of IoT products with restricted power. One of its standout features is seamless integration with the nRF Cloud platform powered by Memfault, enabling effective monitoring without the need for custom cloud infrastructures. This means that engineering teams can gain thorough insights into battery performance across devices, identifying anomalies and optimizing charging strategies based on real-time data.
Adaptation to New Regulations
As new regulatory requirements, such as the EU Battery Regulation 2023/1542, mandate that portable batteries must be easily removable and replaceable by end-users at any point during a product's life cycle, the functionality of the Fuel Gauge v2.0 becomes increasingly vital. It helps manufacturers determine when batteries should be replaced, thus supporting repair initiatives and enhancing product reliability while minimizing warranty costs. The visibility provided by this technology is especially critical for manufacturers with thousands of battery-operated devices, as it can optimize costs across the product lifecycle.
Geir Kjosavik, Product Director of Power Management ICs at Nordic Semiconductor, emphasizes the necessity for such innovation: “Battery performance in the field rarely matches laboratory parameters. With Fuel Gauge 2.0, we bring adaptive, real-time intelligence that was once exclusive to high-end consumer electronics into the realm of battery-powered devices.”
Accuracy and Reliability
Building on the proven accuracy of the state-of-charge (SoC) measurement from the previous Fuel Gauge v1.0, version 2.0 employs a model that continuously adjusts based on the initial profile compared to its actual performance over time. This allows for precise SoH estimation, tracking charging cycles, and long-term degradation trends, ensuring stable accuracy throughout the product’s life—even as the battery ages.
The innovative approach does not require a dedicated fuel gauge IC. Instead, it relies on the embedded nPM1300 IC to measure voltage, temperature, and current, complemented by a smart host-based algorithm. This reduces system costs, simplifies the bill of materials, and vastly improves energy efficiency, especially in idle states.
Insights for Optimization
The system provides manufacturers with vital insights into their products by tracking battery performance over a fleet of devices. By automatically reporting state of health, charge levels, and operational parameters of batteries, Nordic’s solution allows for proactive maintenance and significantly enhances the longevity of devices.
“Memfault’s system was designed to give hardware teams sophisticated insights into their devices,” says François Baldassari, co-founder of Memfault. The seamless connection between Fuel Gauge 2.0 and nRF Cloud provides companies with a powerful, scalable method to understand and improve device performance across fleets.
Conclusion and Availability
The Fuel Gauge v2.0 system is currently in beta testing with selected customers, with broader availability expected in Q2 of 2026. The product will be publicly showcased at the Embedded World 2026 event in Nuremberg, Germany, where demonstrations of real-time battery health reports across various device types will be conducted. This innovative technology marks a significant step forward in enhancing the operational efficiency and sustainability of IoT devices.
For those interested, Nordic Semiconductor will be demonstrating the Fuel Gauge v2.0 at their booth in Hall 4A, Stand 310 during the Embedded World event on March 10-12, 2026.
