Seeking Feedback on Your Interest in Roadtesting a Battery Fuel Gauge Board

rscasny
rscasny over 1 year ago

imageI have a sponsor interested in roadtesting its Fuel Gauge board. I'd like to get your interest. I've added some background information and documents to review.

Here's some info about the board:

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 the nPM1300 Evaluation Kit, which would be provided to you.

Here's some documentation:

    I'm not applying for this road test. because I already used in /products/roadtest/rv/roadtest_reviews/1770/nordic_npm1300_power_management_ic_eval_kit_-_roadtest_review road test review. I already have…

    shabaz said: Odd that the fuel gauge requires a specific microcontroller. I think that their evaluation software "nPM PowerUP app" needs a particular board. The IC itself should work on i2c capable platforms…

    Fuel gauges are the thing that give you the battery charge percentage from past and present voltage/current readings. The characterization mentioned here is only for making sure the percentages it gives…

    Fuel gages are notoriously problematic, so a test system is a great idea.

    It would useful to be able to test and compare other fuel gages using the same test card and software.

    I hope road testers figure out how to compare various fuel gages.

    Completely agree! If the roadtester can compare some of the competing PMICs against nPM1300 it will be a really cool road test!
