Test and Review the Nordic nPM Fuel Gauge Board

Table of contents

We are interested in finding someone to test and review the Nordic nPM Fuel Gauge Board which is a Hardware tool used to profile batteries for accurate estimating of a battery’s state-of-charge.

Description

nPM Fuel Gauge board is a hardware tool to profile batteries to be used for a fuel gauge. The nPM Fuel Gauge board (nPM FG) connects to a compatible Nordic Semiconductor evaluation kit. The purpose of the board is to act as a constant current sink device during battery profiling with nPM PowerUP desktop software. The battery model generated in nPM PowerUP can be used for evaluation of fuel gauge in nPM PowerUP and exported as an include file for use in any application using the Nordic Fuel Gauge algorithm.  To use the nPM Fuel Gauge board you also need a the nPM1300 Evaluation Kit.

Key features

  • Connector for compatible Nordic evaluation kits
  • Constant current sink with heat spreader
  • Used for profiling batteries for Fuel Gauge applications
  • Status indicator LEDs

 

nPM1300 Evaluation Kit nPM1300 EK

nPM1300 EK  is an evaluation Kit for the nPM1300, a highly sophisticated Power Management IC (PMIC) with battery charging and unique system management features. It allows for simple evaluation and code-free configuration of the nPM1300 Power Management IC (PMIC). By connecting to the nPM PowerUP app found in nRF Connect for Desktop, all settings of the nPM1300 can easily be configured through an intuitive GUI and exported as code to be implemented in your MCUs application.

Key Features

  • Seamless integration and code-free configuration with the nPM PowerUP desktop app
  • Male pin headers provide access to all nPM1300 PMIC connections, for easy connection to Nordic Development Kits (DK) and external test equipment
  • Integrated LEDs and pushbuttons allow for evaluation of the built-in LED drivers and GPIOs of the PMIC
  • The kit itself offers JST battery connectors for batteries with or without internal NTC, and male pin headers for access to all nPM1300 connections. In addition, three LEDs and four pushbuttons are implemented for ease of use when evaluating the GPIO and LED diver functionality of the PMIC.

For initial evaluation of the fuel gauging capabilities within the nPM1300, users may use one of the pre-profiled battery models already included in nPM PowerUP. The fuel gauge solution relies on a battery model for best state-of-charge accuracy. Profiling your battery and generating a battery model is a one-time effort where you’ll need an additional nPM Fuel Gauge board for the initial profiling of the battery.

  • I'm a bit confused as to what is meant by "exported as code to be implemented in your MCUs application".
    So for instance, say that I characterized a battery with this pair or boards and that I get some code generated. I understand that this code would be usable on a ESP32 for instance, but what does it need in terms of hardware on top of the MCU?

    Does this code only require an analog readout of the current battery voltage? Or does it need a nPM1300 chip in the final product?

  • Do not know about ESP32 but you could use that code for sure if you have working nRF connect SDK and/or mostly Zephyr RTOS

  • It most likely means that it generates the necessary code for your application to load the necessary configuration parameters to the nPM1300 PMIC for your particular battery that you characterised using nPM PowerUP. This way, the nPM1300 would accurately reflect remaining capacity when used as a fuel gauge.

    Building such profiles is necessary as fuel gauge boards need to know the cell's internal resistance to understand its true voltage when it's under a varying load. The PMIC would be measuring the voltage but also current in/out like a current sense amplifier, working with the battery profile data to determine state of charge at all times.
