摘要： The invention relates to a battery management system for controlling an energy storage assembly, in particular for controlling the charging or discharging process of an energy storage device. The invention further relates to an energy storage assembly having a plurality of storage modules connected electrically in series, which energy storage assembly is controlled by an aforementioned battery management system. The invention further relates to a method for charging or discharging an aforementioned energy storage assembly. A battery management system (100) for controlling an energy storage assembly (10) is specified, which energy storage assembly comprises a plurality of storage modules (11, 12, 13, 14) connected electrically in series, wherein the battery management system (100) comprises: a measuring apparatus for measuring at least one value of a physical quantity of the storage modules (11, 12, 13, 14), a control apparatus (20), which controls a discharging current or charging current drawn from or supplied to the storage modules (11, 12, 13, 14) in dependence on the measured value of a physical quantity of at least one of the storage modules (11, 12, 13, 14), wherein the control apparatus (20) checks if a value of a physical quantity of one of the storage modules (11, 12, 13, 14) changes more quickly than the corresponding values of the physical quantity of the other storage modules (11, 12, 13, 14) of the energy storage assembly (10) or if a value of a physical quantity of one of the storage modules (11, 12, 13, 14) changes more quickly than a specified change value for the value.
