I am trying to do combination of current monitoring + cell voltage delta + time based monitoring for cell balancing.

Is there a way , we could measure current using the CMU's to check it doesn't exceed more than a value.By default my understanding is that AUTO-PAUSE is set when cell voltages are measured , so do we need to turn off measurement , perform cell balance , then again auto-pause and then measure cell voltages ?</P> Mon, 25 Nov 2024 21:35:20 GMT ShivaB 2024-11-25T21:35:20Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Cell-Balancing-S32K348-MC33774-HVBMS800SCT/m-p/2001380#M9800 <P>Hi&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/72088">@mariuslucianand</a>&nbsp;,</P><P>I was trying to implement cell balancing algorithm on S32K348 using MBDT blocks.</P><P>1.

I see from the data sheet some configuration could be set to enable this but I am not clear how could i set voltage threshold for cell balance to be active?&nbsp; My understanding is that voltage based cell balancing is automatically enabled but I am unable to see how I can set threshold in MBDT ?&nbsp;</P> Mon, 02 Dec 2024 07:54:11 GMT https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Cell-Balancing-S32K348-MC33774-HVBMS800SCT/m-p/2004908#M9828 ShivaB 2024-12-02T07:54:11Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Cell-Balancing-S32K348-MC33774-HVBMS800SCT/m-p/2013752#M9858 <P>Please respond on this query.&nbsp;</P> Fri, 13 Dec 2024 17:11:06 GMT https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Cell-Balancing-S32K348-MC33774-HVBMS800SCT/m-p/2013752#M9858 ShivaB 2024-12-13T17:11:06Z
