Battery management system for controlling an energy storage device and method for charging and discharging an energy storage device

摘要

The present invention relates to a battery management system for controlling an energy storage device, in particular for controlling the charging or discharging of an energy storage device. In addition, the invention relates to an energy storage device having a plurality of memory modules connected in series, which is controlled by a previously mentioned battery management system. Furthermore, the present invention relates to a method for charging or discharging an energy storage arrangement mentioned above. The invention relates to a battery management system (100) for controlling an energy storage arrangement (10) having a plurality of memory modules (11, 12, 13, 14) connected in series, the battery management system (100) comprising: a measuring device for detecting at least one value of a physical size of the memory modules (11, 12, 13, 14), a control device (20) which, depending on the detected value of a physical quantity of at least one of the memory modules (11, 12, 13, 14), a discharge current or charging current the control module (20) checks whether a value of a physical size of one of the memory modules (11, 12, 13, 14) changes faster than the memory modules (11, 12, 13, 14) the corresponding values of the physical size of the other memory modules (11, 12, 13, 14) of the energy storage device (10) or whether a value of a physical size of one of the spoke rmodule (11, 12, 13, 14) changed faster than a predetermined value of change for the value.
