Introduction

In a major announcement at the Embedded World 2026 event, Nordic Semiconductor has unveiled Fuel Gauge v2.0, a groundbreaking technology designed to revolutionize battery health monitoring for Internet of Things (IoT) devices. This new solution promises to not only provide precise estimations of remaining battery charge but also offers advanced features that enable smarter, more durable connected devices.

Key Features of Fuel Gauge v2.0

The latest iteration of the Fuel Gauge enhances its capabilities with a focus on the State of Health (SoH) of batteries, adaptive battery modeling, and fleet observability via integration with nRF Cloud and Memfault services. Key features include:

• - Enhanced State of Health Estimation: Offer insights about battery longevity and performance, facilitating proactive maintenance for manufacturers.
• - Adaptive Modeling: Continuously compares the original battery profile with actual usage over time, improving accuracy in battery management.
• - Seamless Cloud Integration: Allows for efficient tracking and reporting of battery health without requiring custom cloud infrastructures.

Revolutionizing Battery Management for IoT

Battery management has traditionally been a challenge, particularly in the field of IoT where devices often operate in unpredictable environments. Geir Kjosavik, Product Manager for Power Management ICs at Nordic, noted that the behavior of batteries in real-world applications frequently deviates from laboratory conditions. Fuel Gauge v2.0 addresses this issue by delivering adaptive intelligence that was once reserved for high-end electronic products, thus changing the landscape for billions of battery-operated devices.

Implications for Device Manufacturers

The implications of Fuel Gauge v2.0 for device manufacturers are significant. As regulatory requirements tighten around battery management and replacement—such as the EU Regulation 2023/1542 aiming for easier battery removal and replacement—this technology enables manufacturers to create more reliable and sustainable products. Enhanced SoH analytics mean that manufacturers can predict when batteries need replacing, reducing warranty costs and improving product reliability over time.

Simplified Battery Management

Traditional battery gauge ICs often rely on fixed models or coulomb counting, which can drift over time. Nordic’s innovative approach utilizes built-in measurements of voltage, temperature, and current within their power management chips, reduced to a lower system cost without sacrificing precision. The implementation of intelligent algorithms executed by the main microcontroller allows for power savings compared to conventional solutions.

Fleet-Wide Monitoring and Maintenance

Fuel Gauge v2.0 thrives on its integration with nRF Cloud through the Memfault platform, allowing for real-time monitoring of battery health across an entire fleet of devices. Developers can analyze performance metrics, identify anomalies, and optimize charging parameters effectively. This capability is pivotal for operations managing thousands or millions of battery-powered devices.

Future-Proofing Device Sustainability

As manufacturers strive for compliance with battery regulations, the features provided by Fuel Gauge v2.0 are crucial for ensuring that devices can be maintained proactively. Understanding when batteries need to be replaced fosters a culture of repairability and sustainability, contributing to environmental goals while enhancing device reliability.

Conclusion

With Fuel Gauge v2.0, Nordic Semiconductor is at the forefront of battery management technology. The product's dual focus on precision and adaptability offers a new way for users and manufacturers alike to engage with battery-operated technology. As we move further into an increasingly connected world, the importance of reliable, smart battery management solutions cannot be overstated. Available for testing now, broader accessibility for Fuel Gauge v2.0 is anticipated in the second quarter of 2026.
