Nordic Semiconductor introduces precise, adaptive battery health-monitoring to enable smarter, longer‑lasting IoT devices

Nordic Semiconductor, a global leader in low-power wireless connectivity solutions, today announces Nordic Fuel Gauge v2.0, a major upgrade of its highly accurate software-based fuel gauge solution for the award-winning nPM1300, and nPM1304 Power Management ICS, at Embedded World 2026. The release adds sophisticated State‑of‑Health estimation, adaptive battery modeling, and long‑term fleet analytics capabilities, extending advanced battery management to a wide range of power‑constrained IoT products.   

Nordic Fuel Gauge v2.0 will empower manufacturers to build more reliable, sustainable, and longer-lasting products while also meeting emerging battery-replacement mandates. This includes the European Union Batteries Regulation 2023/1542, which dictates that portable batteries be “readily removable and replaceable by the end-user at any time during the lifetime of the product”. The release enables manufacturers to determine when batteries need to be replaced, supports right‑to‑repair initiatives, improves product reliability, and reduces warranty costs. 

“Battery behavior in the field rarely matches what you see in the lab,” said Geir Kjosavik, Product Director PMICs at Nordic Semiconductor. “With Fuel Gauge v2.0, we’re bringing adaptive, real‑world intelligence that was once exclusive to premium consumer electronics into the IoT space. It's a game changer for billions of battery-powered devices.”

Fleet‑wide battery intelligence through nRF Cloud powered by Memfault 

Fuel Gauge v2.0 integrates seamlessly with Nordic’s cloud lifecycle services - nRF Cloud powered by Memfault. Devices can automatically report State-of-Health, State-of-Charge, and battery‑performance metrics without requiring custom cloud infrastructure. This enables engineering and operations teams to monitor fleet‑wide battery health, identify anomalies, optimize charging parameters, and improve future hardware designs using real‑world data. 

“Memfault was built to make sophisticated device insights accessible to every hardware team,” says François Baldassari, founder of Memfault and VP Software Services at Nordic Semiconductor. “By connecting Fuel Gauge v2.0 seamlessly to nRF Cloud, we give companies a powerful, scalable way to understand and improve device behavior across entire fleets. It’s the future of battery intelligence.”
