An assembly includes a plurality of electrically interconnected battery cells in a housing. An electrically insulating coolant fluid that directly surrounds the plurality of electrically interconnected battery cells flows around the plurality of electrically interconnected battery cells in the housing. An aircraft having an assembly of this type is also provided.

A method for the thermal treatment of a component, in particular a metal powder injection molded component (MIM component) including a nickel base alloy, wherein, after sintering, in particular immediately after sintering, in the injection molding process, the component is exposed for a predetermined holding time to at least one treatment temperature below the sintering temperature. A component, in particular an MIM component, and to an aircraft engine.

An electrical energy storage device includes prismatic energy storage cells arranged adjacent to one another such that interfaces of adjacent storage cells run at a distance from one another such that the interfaces of the adjacent storage cells form an intermediate space. A respective first layer is arranged between the interfaces of adjacent storage cells, the first layer abutting one of the two interfaces of the adjacent storage cells under pressure. Either the respective first layer also abuts the second of the two interfaces of the adjacent storage cells under pressure, or a second layer is arranged between the interfaces of adjacent storage cells, the second layer abutting the second of the two interfaces of the adjacent storage cells under pressure. A heat-conducting device is arranged in or between the first layer and the second layer is conducted out of the intermediate space between the adjacent storage cells.

Electrical energy storage device with efficient heat dissipation

In order to determine the charging capacity state and the state of health of an electrical energy store of a battery system (BS; BS) with little effort, a measuring device (ME) is proposed, which measuring device injects, into a drive train which is available for first or second loads (VR; VR) and has an AC/DC converter (ADC) or a DC/DC controller (DDC) on the DC side of the AC/DC converter (ADC) or of the DC/DC controller (DDC), a sinusoidal voltage harmonic with a varied frequency or a sinusoidal current with a varied frequency as a particular measurement signal which is transmitted to the battery system (BS; BS). The current response or voltage response, which has been purged of unwanted influences, is then determined for each measurement signal at the battery system (BS; BS), from which response phase shifts are determined in each case, and parameters for a statement relating to the charging capacity state or the state of health of the battery system (BS; BS) are in turn determined therefrom.
