Norwegian low-power wireless connectivity company Nordic Semiconductor announced on July 6 the official release of Nordic Fuel Gauge v2.0 for its nPM1300 and nPM1304 power management ICs (PMICs). The solution is designed to monitor both the charge level and health of rechargeable batteries in Internet of Things (IoT) devices without requiring a dedicated fuel-gauge IC.

The new solution is available through nRF Connect SDK version 3.4.0-rc2. Nordic said it enables IoT developers to monitor battery status throughout a product's lifecycle, from design validation to field deployment and end-of-life. Manufacturers can use the data to track battery aging trends and predict replacement timing.

The solution estimates battery state of charge and aging trends using built-in voltage, temperature and current measurements from the nPM1300 and nPM1304, combined with a host-based algorithm.

Version 1.0 supported only battery charge estimation. Version 2.0 continuously compares the original battery profile with actual operating behavior to estimate battery state of health and monitor degradation over time. For devices using multiple replaceable battery packs, it can track the health of each pack individually.

The solution also integrates with nRF Cloud, enabling automatic reporting of battery charge status, battery health and performance metrics. Development and operations teams can monitor battery conditions across multiple devices through a single dashboard, allowing them to detect anomalies early and optimize charging configurations.

Nordic said the functionality can help manufacturers comply with the European Union Batteries Regulation (EU) 2023/1542, which requires portable batteries to be readily removable and replaceable by end users.
