Low power high accuracy fuel gauging

tailored for embedded IoT

Estimating state-of-charge

in lithium batteries is crucial for optimizing performance and ensuring safe operation. There are several methods used to estimate the state-of-charge of single-cell lithium batteries. 

All methods have their benefits and drawbacks, but some benefits are more desired and some drawbacks are less severe than others. For the nPM1300, we decided that algorithm based fuel gauging was the way to go.

Coloumb counting fuel gauge IC 


 + High accuracy  + No additional energy usage  + Best accuracy 

 + Ultra-low power consumption  + No additional cost added to your bill-of-materials

 + No current draw at system-off    

 + No added cost to your bill-of-materials    


 - Needs to be supported by PMIC  - Very low accuracy - Draws current even at system-off to keep coloumb counter running
     - Severly affected by temperature - Expensive, adds components to your bill-of-materials (BoM)

To take advantage of the fuel gauging capabilities of the nPM1300, you can read the application note explaining how to create a virtual model of your battery for use with the fuel gauge sample in the nRF Connect SDK.

Guide to profile your batteries with nPM FG

Low power high accuracy fuel gauging tailored for embedded IoT

To accurately estimate the battery state-of-charge in percent, from 0 to 100 %, the nPM1300's fuel gauge functionality uses a virtual model of your battery along with the battery's temperature, voltage and the current measured by the PMIC. The estimation algorithm can then be run on any Arm Cortex M4 or M33, like those found in the nRF52, nRF53 and nRF91 Series and does not require additional hardware beyond this.  

The battery model is created by doing an analysis of your specific battery, in your own lab, with the help of the nPM1300 Evaluation Kit along with a dedicated nPM Fuel Gauge board.
