Abstract

The invention relates to a battery cell (1) for a battery of a motor vehicle comprising a galvanic element (2) with a first electrode (4) and a second electrode (5), a battery cell housing (3) with a first connection (6) and a second connection (7), at least one sensor device (9, 10, 11, 2, 13, 14, 15, 16, 17, 18) for determining a physical and / or chemical characteristic of the battery cell (1), and a control device (19), wherein the galvanic element (2) is arranged in the battery cell housing (3), wherein the battery cell (1) has a switching device (S) by means of which the first connection (6) and the second connection (7) can be electrically connected, and the control device (19) is designed to close the switching device (S) for the purpose of shorting the battery cell (1), in accordance with the physical and / or chemical characteristic determined by the at least one sensor device (9, 10, 11, 12, 13, 4, 15, 16, 17, 18). The invention also relates to a battery and a motor vehicle.

Description

technical field [0001] The invention relates to a battery cell for a motor vehicle battery, the battery cell having an electrical component comprising a first electrode and a second electrode, a battery cell housing comprising a first connection end and a second connection end, at least one Sensor device and control device for detecting physical and / or chemical properties of a battery cell, wherein the electrical components are arranged in the battery cell housing. The invention also relates to a battery and a motor vehicle. Background technique [0002] In known battery cells, an electrical component is usually arranged in each case in the battery cell housing. In order to provide a defined voltage or defined current, a plurality of battery cells can be connected to form a battery. These batteries are used today, in particular as traction batteries, in motor vehicles, for example in electric or hybrid vehicles, for driving the motor vehicle. However, the battery must mee...
