Abstract: A storage device configured to store electrical energy, includes at least one storage element having an element housing which has at least one accommodating chamber and at least one element base which at least partially downwardly delimits the accommodating chamber in an installation position of the storage device. The storage device includes at least one storage means, accommodated in the accommodating chamber, configured to store electrical energy, wherein the at least one storage means comprises at least one degassing unit configured to discharge fluid, which is released in the accommodating chamber, from the accommodating chamber. The degassing unit is provided on the element base and is configured to downwardly discharge fluid from the accommodating chamber with respect to the installation position of the storage device.

Abstract: A storage device for storing electrical energy includes at least one storage cell which has a cell housing, a receiving chamber delimited by the cell housing, and at least one storage element accommodated in the receiving chamber for storing electrical energy, as well as a safety apparatus. The safety apparatus has a separating device as a first safety device designed to separate at least the storage cell from a circuit of the storage device, a short-circuit device as a second safety device designed to short-circuit at least the storage cell, and a degassing unit as a third safety device designed to degas the receiving chamber. The safety devices are designed to successively switch from a deactivated state into an activated state during a critical variation of the condition of the storage cell.

Abstract: A storage device for storing electrical energy includes at least two storage cells. Each storage cell has a cell housing, an accommodating space delimited by the cell housing, and at least one storage element for storing electrical energy. The storage element is accommodated in the accommodating space. At least one thermally conductive heat-conducting element is provided, by which heat can be deliberately transferred from a first of the storage cells to the second storage cell.

Abstract: A cover device is provided for a battery housing of a traction battery of a motor vehicle for covering a receptacle chamber of the battery housing provided for receiving at least two battery cells of the traction battery. The cover device has a top side facing a surrounding region and a bottom side facing the receptacle chamber. The bottom side has a first region associated with degassing elements of the battery cells having a first heat resistance against a hot gas flowing out of the degassing elements. The bottom side has a second region having a second heat resistance which is smaller compared to the first heat resistance.

Abstract: A storage cell that is configured to store electrical energy includes a cell housing which is prismatic on an outer periphery, and a jelly-roll winding accommodated in the cell housing and which has two opposing broad sides, two opposing first narrow sides and two opposing second narrow sides. The storage cell also includes a first electrode tab which is electrically contacted with a first electrode of the jelly-roll winding and protrudes from the first electrode, and a second electrode tab which is electrically contacted with a second electrode of the jelly-roll winding and protrudes from the second electrode. One of the first and second electrode tabs is arranged on a first one of the two opposing first narrow sides and is electrically connected thereto by a connection element extending from a first one of the two opposing first narrow sides onto a first one of the two opposing second narrow sides.
