US 2024/0204524 A1 · BATTERY BANK POWER SYSTEM

Abstract

One example includes battery bank power system. The system includes a plurality of battery bank systems. Each of the battery bank systems can include a battery management system and a plurality of battery racks. Each of the battery racks can include a plurality of battery modules and each of the battery bank systems can be electrically connectable to an inverter bus. The system also includes an inverter that is electrically coupled to the inverter bus and is configured to provide an inverter current from the battery bank systems to a power grid in a discharging operation or to receive the inverter current from the power grid to the battery bank systems in a charging operation. The system further includes a battery system controller that is communicatively coupled to the battery management system of each of the battery bank systems to selectively control the battery bank systems.
