It&#8217;s a game changer for billions of battery-powered devices.&#8221;<\/p>\n<h2>nRF Cloud<\/h2>\n<p>As you would expect, v2.0 integrates with Nordic&#8217;s own cloud lifecycle services \u2013 <a rel=\"image\" href=\"https:\/\/nrfcloud.com\/\" target=\"_blank\" rel=\"nofollow\">nRF Cloud<\/a>.<\/p>\n<p>The IoT devices can automatically report State-of-Health, State-of-Charge, and battery-performance metrics without requiring custom cloud infrastructure.<\/p>\n<p>Fran\u00e7ois Baldassari, founder of Memfault and VP Software Services at Nordic Semiconductor comments as follows.<\/p>\n<p>&#8220;Memfault was built to make sophisticated device insights accessible to every hardware team. 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&#8217;s the future of battery intelligence.&#8221;<\/p>\n<p>The new version of the software is currently beta sampling to customers, with wider availability coming in June 2026. Its announcement comes from Embedded World 2026.<\/p>\n<h2>Adaptive model<\/h2>\n<p>As mentioned, Nordic highlights that version 2.0 introduces an adaptive model. That is to say, one that continuously compares the original battery profile with the battery&#8217;s actual behaviour over time.<\/p>\n<p>This is designed to enable more accurate State-of-Health estimation, track charge-cycles and long-term degradation trends, even as batteries age.<\/p>\n<p>Nordic writes:<\/p>\n<p>&#8220;Traditional fuel-gauge ICs rely on fixed models or coulomb counting, which can drift over time. Nordic&#8217;s approach requires no dedicated fuel-gauge IC and instead uses the nPM1300&#8217;s built-in voltage, temperature, and current measurements, together with a smart host-based algorithm. This will deliver dedicated IC-level accuracy at a lower system cost, with reduced Bill of Materials complexity, and consume no power during sleep \u2013 significantly saving power compared to competing solutions.&#8221;<\/p>\n<p><em>Image: The nPM Fuel Gauge board (nPM FG), which connects to compatible Nordic Semiconductor evaluation kits.<\/em><\/p>\n<p><em>See also<\/em>: <a rel=\"image\" href=\"https:\/\/www.electronicsweekly.com\/news\/products\/rf-microwave-optoelectronics\/ces-nordic-adds-npu-to-wireless-mcu-2026-01\/\" target=\"_blank\" rel=\"noopener\">Nordic adds NPU to wireless MCU<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nordic Semiconductor has updated its Fuel Gauge software to v2.0.
