低功耗無線連接解決方案的全球領導者 Nordic Semiconductor 今日在 Embedded World 2026 展會上，宣布為其屢獲殊榮的 nPM1300 和 nPM1304 電源管理 IC 推出高精度軟體式電池管理解決方案的重大更新：「Nordic Fuel Gauge v2.0」。
此次更新透過新增先進的健康狀態（SoH）估計、適應性電池模型和長期設備群組分析功能，將先進的電池管理擴展到廣泛的電力受限物聯網產品。
Nordic Fuel Gauge v2.0 協助製造商開發更可靠、更永續、更長壽的產品，同時也能符合新近強化的電池更換法規要求。這包括歐盟電池法規（2023/1542），該法規規定電池在產品整個生命週期中，必須能隨時被終端使用者輕鬆拆卸和更換。此發布讓製造商能夠適當判斷電池更換時機，支持「維修權」，提高產品可靠性並降低保固成本。
Nordic Semiconductor PMIC 產品總監 Geir Kjosavik 表示：「實際環境中的電池行為很少與實驗室測量結果一致。Fuel Gauge v2.0 將過去僅限於高階消費性設備的適應性、真實世界智慧帶入物聯網領域。這將為數十億台電池供電設備帶來革命性的變化。」
透過整合 Memfault 的 nRF Cloud 提供設備群組的電池智慧功能
Fuel Gauge v2.0 與 Nordic 的雲端生命週期服務 nRF Cloud powered by Memfault 無縫整合。設備無需製造商建置自有雲端基礎設施，即可自動報告其電池健康狀態（SoH）、充電狀態（SoC）和各種效能指標。這使得工程和營運團隊能夠監控其整個設備群組的電池狀態，偵測異常，優化充電參數，並
常見問題
What is Nordic Fuel Gauge v2.0?
Nordic Fuel Gauge v2.0 is a significant update to Nordic Semiconductor's software-based battery management solution for its nPM1300 and nPM1304 power management ICs. It offers advanced State-of-Health (SoH) estimation, adaptive battery modeling, and long-term fleet analysis capabilities for IoT devices.
What are the main benefits of Nordic Fuel Gauge v2.0?
The main benefits include enabling smarter and longer-lasting IoT devices, improving product reliability, supporting compliance with new battery regulations (like the EU Battery Regulation), facilitating the 'Right to Repair', and reducing warranty costs for manufacturers.
How does Nordic Fuel Gauge v2.0 help with battery replacement regulations?
It helps manufacturers accurately determine when batteries need replacing, supporting regulations like the EU Battery Regulation (2023/1542) which mandates that batteries must be easily removable and replaceable by the end-user throughout the product's lifetime.
What is the significance of the 'adaptive' nature of the battery modeling?
The adaptive modeling allows the system to learn and adjust to real-world battery behavior, which often differs from lab measurements. This provides more accurate intelligence for battery management in actual operating conditions, a feature previously limited to high-end consumer devices.
How does nRF Cloud powered by Memfault integrate with Fuel Gauge v2.0?
Fuel Gauge v2.0 seamlessly integrates with nRF Cloud, allowing devices to automatically report battery SoH, SoC, and performance metrics. This enables manufacturers to monitor their entire fleet's battery status without needing to build their own cloud infrastructure.
