A method for determining a charging profile from a large number of charging profiles for a current charging process for charging an electrical energy store includes determining a current state of the energy store, determining the charging profile from the large number of charging profiles based on the current state of the energy store, and charging the energy store based on the determined charging profile.

System and method for determining charging profiles

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.

Storage device for storing electrical energy, in particular for a motor vehicle

An energy storage device for a motor vehicle includes a plurality of round cells for electrochemically storing energy, and a storage housing in which the plurality of round cells is provided. In the installed position, the round cells run substantially parallel to the vehicle transverse axis. The round cells are arranged within the storage housing in multiple layers in the direction of the vehicle vertical axis, wherein the number of layers varies in the direction of the vehicle longitudinal axis.

Energy storage device for a motor vehicle, motor vehicle, and production method

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.

Storage device for storing electrical energy, in particular for a motor vehicle, and motor vehicle

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.

Storage device for storing electrical energy, in particular for a motor vehicle, motor vehicle comprising such a storage device, and method for operating such a storage device

A storage module stores electrical energy. The storage module has a first storage cell and a second storage cell, each having a positive terminal and a negative terminal. The storage module includes a contact bridge, which connects one terminal of the first storage cell to one terminal of the second storage cell in an electrically conductive manner. The contact bridge is designed to reduce an electrical resistance between the electrically connected terminals of the first storage cell and of the second storage cell with rising temperature.

Storage module having heating measures

An electrical energy-storage unit has a plurality of electrically coupled and interchangeable storage modules each with a multiplicity of storage cells connected in series or in parallel. The energy-storage unit has storage modules of a first type, which have a certain energy density. The energy-storage unit has storage modules of a second type which have a higher energy density than the storage modules of the first type. At least two storage modules of the second type fit into the spatial volume of a storage module of the first type.
