BQ40Z60 LED for the discharging status.

Other Parts Discussed in Thread: BQ40Z60

Hi Tom,

I have used BQ40Z60 for my battery manage project. It works very well,

I have used four LEDs for the charging status, when the charger power supplier connected.

Right now I would like to let LEDs show the discharging status when there is no power supplier connected (just show the capability of the battery remaining).

So what settings I need to enable that function?

Thanks,

There should not be a special setup to display the SOC during discharge. The device is not designed to display it continuously during discharge or rest, just when the button is pushed.

Hi Tom,

Thanks for your reply.

I would like to let LEDs show the discharging status when a button is pressed, I found there are settings in LED support (in Data Memory) shows the DSG threshold percentage.

How to use those settings to display the battery status?

Thanks,

Jun

You can set the SOC threshold where you want the LED to light. If LED3 is set to 75%, then it will go out when the SOC drops below 75%.
