Active Battery Balancer
We are investigating an active battery balance system move up to 2 amps in and out of 12 volt batteries connected togther in in a 648 volt series string of batteries. There is a common 72 volt battery system that can be used as a buffer.
The question is if there is an isolated PI switch topology that could be used to move these 2 amps in either direction or should each 12 battery have both an isolated buck and isolated boost circuit to move the 2 amps into and out of the 72 volt buffer battery.
Thanks
Dave

Still trying to figure out how to get through to an application engineer to discuss options for the simple request below.
Hello Dave,
Thank you for interested in using PI products.
Do you have a block diagram about how the 12V battery, 648V battery and 72V buffer connected? And how much is the power are you trying to converter here.
Best Regards
Just following up, if no one responds here, how do you get engineering support to answer simple questions like this?
