PCS energy storage system battery series and parallel combination
. A parallel connection of battery cells forms a logical cell group, and these groups are then connected in series. The connected battery cells and the BMS, sometimes with a PCS, form battery modules. Several modules. . The battery comprises a fixed number of lithium cells wired in series and parallel within a frame to create a module. The modules are then stacked and combined to form a battery rack. Battery racks can be connected. [pdf]FAQS about PCS energy storage system battery series and parallel combination
