Battery level estimation (fuel gauge)

Hi Dialog,

We're working on a battery powered application with the da1469x. As the chip has a built-in charger but not a fuel gauge, can you recommend a way to estimate battery level?
In other threads I've read about a "software-based fuel gauge algorithm making use of the very accurate Battery monitor". An example of this would get us started. Thanks for your help.

Best regards,
Richard

Hi Richard,

Hi Richard,

Thanks for your question online and for your interest in DA1469x BLE solution. We have recently released the UM-B-134: DA1469x State of Charge Functionality on the DA1469x support page. I would recommend you to have a look into this document as it describes the State of Charge calculation and gives an overview of the whole process of charging and discharging a battery.

Please let me know if you need any extra clarifications.

Thanks, PM_Dialog

Hi PM_Dialog,

Hi PM_Dialog,

Thanks that looks useful.
The document references a DA1469x SoC software example. Is that software available for download?

Thanks,
Richard

Hi Richard,

Hi Richard,

The DA1469x SoC software example is now available for download. It’s under Software Applications & Examples: Peripheral Drivers/Adapters section of the DA1469x product webpage.

For your convenience, this is the download link : DA1469x Battery SOC Fuel Gauge Demo Application

Any feedback would be more than welcome!

Thanks, PM_Dialog

Hi PM_Dialog,

Hi PM_Dialog,

Thanks for that. We'll test it to see if it gets the battery level estimation right. If we have issues or feedback I'll post it.

Regards,
Richard
