BMS during Plug-In Charging??

I'm just trying to wrap my head around the this Plug-in charging function as I begin my PIS conversion of my Gen2.
I hadn't really considered this question until I got into an email exchange with Gregory McCea at ElCon/Electric Conversions, regarding their battery chargers. (Elcon PFC-1500 or 2500 models) He was referring to choice of charging rate or algorithms for the 10Kwh PIS battery pack I will be using. He states; "The larger PFC2500 outputs almost 8A at 220vac and 5A at 115vac. The most often used charge curve is #521a .
This depends on your BMS settings."

Intially, my thoughts were, the hybrid systems are nornally shut down during charging. Right?? Then after giving this some thought, the PIS BMS boards are installed on the individual battery cells, one of each cell. Are they actively monitoring during "plug-in" charging. How do they react or interact with the charger. And if so, do they go passive once the charge is complete? Or do they continue to monitor the battery state and activate a :"trickle or float charge" over a longer period of time if the charger still has power to it?

It should be noted, I am referring to the PIS more recent BMS, not the earlier or the miniBMS sometime assosiated with the PIS plug-in converstion.

Still learning with each post.

Alexander,
My experience, so far, has been with the PIS conversion and that is very limited, as I am still learning presently trouble shooting a BMS/cell loop problem in my system.
It is my understanding that your charger should be set to Algoritm 521a for the PFC1500. Or initial start up Red LED flashes 9 time than goes to check for charge enable signal from the controller. You should read your installation/operating instruction on procedures to re-select the correct Alg if it is not correct. If you have further question, then I recommend that you contact Sayyed, by email at Elcon. (Electric Conversions).

Since you refer to your BMS boards as MiniBMS, then I would suspect this is not a PIS system since they have their own BMS board, often referred to a s Cell Boards. MiniBMS board are from a different source and PIS hasn't used them for a few years.
