Abstract
The invention relates to an energy storage system for a repeated drawing/intake, storage and release of electrical energy having a control unit and an energy store comprising a plurality of storage cells that are organized in storage modules, with the control unit being configured to separately determine the state of charge of at least some of the storage cells. The control unit is configured to recognize whether at least one storage cell should be removed; to electrically disconnect the storage cell to be removed from the remaining storage cells after the recognition that at least one storage cell should be removed; to recognize whether the disconnected storage cell has been replaced by a new storage cell; and to electrically connect the new storage cell to the remaining storage cells.
Claims17
An energy storage system for a repeated intake, storage and release of electrical energy, the energy storage system comprising
- a control unit and an energy store comprising a plurality of electrical storage cells that are organized in storage modules, wherein the control unit is configured to separately determine a state of charge of at least some of the storage cells,
- wherein the control unit is further configured
- to recognize whether at least one storage cell should be removed;
- to electrically disconnect the storage cell to be removed from the remaining storage cells after the recognition that at least one storage cell should be removed;
- to recognize whether the disconnected storage cell has been replaced by a new storage cell;
- and
- to electrically connect the new storage cell to the remaining storage cells;
- wherein the control unit is configured to determine a temporal operating pattern of the energy storage system;
- and
- wherein the temporal operating pattern comprises statistics, with the statistics of the temporal operating pattern indicating future times at which and a probability with which a respective state of charge of the energy store is present and whether a discharge or a charge of the energy store takes place at these times.
An energy storage system for a repeated intake, storage and release of electrical energy, the energy storage system comprising
- a control unit and an energy store comprising a plurality of electrical storage cells that are organized in storage modules, wherein the control unit is configured to separately determine a state of charge of at least some of the storage cells,
- wherein the control unit is further configured
- to recognize whether at least one storage cell should be removed;
- to electrically disconnect the storage cell to be removed from the remaining storage cells after the recognition that at least one storage cell should be removed;
- to recognize whether the disconnected storage cell has been replaced by a new storage cell;
- and
- to electrically connect the new storage cell to the remaining storage cells;
- wherein at least some of the storage cells are connected in series, with the storage cell to be removed being bridged by means of a bypass line after the disconnection of the storage cell to be removed;
- and
- wherein the bypass line has the same resistance as the storage cell to be removed.
