AD8450 and AD1972

HI all,

I want to design BMS by using AD8450 and AD1972, 64 pcs of batteries connect to same input source, and battery charge independently,

AD1972 have energy recycle feature, so the energy on battery can discharge back to input bus. can 64 pcs battery discharge to the input bus at the same time? maybe i need to replace the ESS on input bus for preventing input voltage rising, i just thinking the current balancing problem when 64pcs battery discharge at the same time

Thanks,

Sam Choi
