Abstract
An embodiment of this application provides an energy storage system, and a method and an apparatus for controlling the energy storage system. The method includes: selecting a plurality of target modules from all modules contained in an electric cabinet, where a voltage of each of the plurality of target modules is greater than or equal to a voltage of a remaining module; and controlling a DC-DC circuit of the plurality of target modules to increase an output voltage. The technical solution provided in the embodiment of this application can solve the problem that state-of-charge (SOC) imbalance between different modules affects performance of the energy storage system.
