Accurate fuel gauging is essential for any battery‑powered device, giving users clear and reliable insight into how much energy is left and helping avoid unexpected shutdowns.
Nordic’s fuel gauging provides accurate state of charge information for all supported battery types. Battery state of health is also supported for rechargeable batteries - tracking actual capacity and aging over time to understand how the battery performs throughout its lifetime. This deeper insight helps devices stay reliable for longer and makes rechargeable battery replacement more predictable.
By combining high accuracy with ultra‑low power operation - including zero power consumption in sleep - and low system cost, the Nordic algorithm-based fuel gauge solution delivers accurate battery information without extra components, licensing fees, or impact on battery life.

nPM1304 EK 评估套件
用于具备电池充电和独特系统管理功能的高级PMIC nPM1304的评估套件
nPM1304评估套件可实现nPM1304电源管理集成电路（PMIC）的简易评估与免编程配置。通过连接nRF Connect for Desktop中的nPM PowerUP应用程序，所有nPM1304设置均可借助直观图形界面轻松配置，并导出为代码以在您的MCU应用中实现。
- 通过nPM PowerUP桌面应用实现无缝集成与免编码配置
- 公头针脚排针提供所有nPM1304电源管理IC（PMIC）接口接入，便于连接Nordic开发套件（DK）及外部测试设备
- 集成LED指示灯与按键可评估PMIC内置LED驱动器及通用输入输出（GPIO）功能
- 内含20毫安时电池
该套件本身配备了适用于带/不带内部NTC电池的JST电池连接器，以及用于访问所有nPM1304接口的公针脚排针。此外，还集成了三个LED和四个按键，便于评估PMIC的GPIO和LED驱动功能。
用户可直接使用nPM PowerUP中预先配置的电池模型，初步评估nPM1304的电量计能力。该电量计方案需依托电池模型才能实现最佳电量状态精度。电池建模仅需一次性操作，nPM1304评估套件已内置所需的可编程负载电路。
