Embodiment Construction

[0039] The examples described below relate to preferred embodiments of the present invention. In this exemplary embodiment, the described components of this embodiment represent individual features of the invention which are to be considered independently of one another, which respectively improve the invention independently of one another and which are thus to be distinguished individually or otherwise from The combinations shown are considered to be part of the invention. Furthermore, the described embodiments can also be supplemented by the features of the invention that have already been described.

[0040] The drawing shows a battery 1 , of which only five battery cells 2 are shown schematically. Only the battery cell housing is visible here for the battery cells 2 . An electrical component is arranged in each case in the battery cell housing. The battery cells 2 are electrically connected here to form a battery 1 via a respective electrical connection element 3 in the...

Abstract

The invention relates to a battery (1) having at least two battery cells (2) interconnected by means of at least one electrical connecting element (3), a superordinate control device (6), wherein each battery cell ( 2) having at least one electrical component, a battery cell housing for accommodating the electrical component, at least one sensor device (7, 8, 9) for acquiring physical and / or chemical properties of the battery cell (2) and a user A communication device (10, 11) for communicating with the superordinate control device (6), wherein the superordinate control device (6) is designed to control the battery cells (2) to Energy flow in and / or from at least one of the battery cells (2). The invention also relates to a motor vehicle having such a battery ( 1 ).

Description

technical field [0001] The invention relates to a battery having at least two battery cells connected to one another by means of at least one electrical connecting element, a superordinated control device, wherein each battery cell has at least one electrical component, a battery for receiving the electrical component A cell housing, at least one sensor device for detecting physical and / or chemical properties of the battery cells, and a communication device for communicating with the superordinate control device. The invention also relates to a motor vehicle with a battery. Background technique [0002] The prior art already discloses the electrical connection of the individual battery cells to form a battery or battery system and the secure mechanical fastening thereof. These batteries are used today as traction batteries in motor vehicles, for example in electric vehicles or hybrid vehicles, for driving the motor vehicle. However, the use of batteries in motor vehicles m...
