Summary:A battery system, a method of controlling the battery system, and an energy storage system including the battery system. The battery system includes: a plurality of tray battery management systems (BMSs) controlling at least one battery tray formed of a plurality of battery cells; and a rack BMS transmitting a synchronization signal to the tray BMSs to measure monitoring data, wherein the tray BMSs transmit the synchronization signal to a next tray BMS, measure monitoring data of the at least one battery tray via the transmitted synchronization signal, and transmit the measured monitoring data to the rack BMS. Accordingly, measurement accuracy of battery voltages and battery charging/discharging currents may be improved, and also, calculation accuracy of state of charge (SOC) and state of health (SOH) may be improved.
