Abstract

A sensor apparatus (210) for a battery cell of an electrical energy store is proposed. In this case, the battery cell (200) has a housing (202). The sensor apparatus (210) has an acquisition device (100) for acquiring sensor data with regard to the battery cell (200). In this case, the acquisition device (100) can be arranged or is arranged inside the housing (202) of the battery cell (200) and has a coupling element (110) for inductively emitting the sensor data and for inductively receiving electrical power. The sensor apparatus (210) also has an evaluation device (220) for evaluating the sensor data. In this case, the evaluation device (220) can be arranged or is arranged inside or outside the housing (202) of the battery cell (200) and has a transmission element (222) for inductively transmitting electrical power to the acquisition apparatus (100) and for inductively receiving the sensor data from the acquisition apparatus (100).

Description

technical field [0001] The invention relates to a sensor device for a battery cell of an electrical energy store, a battery cell of an electrical energy store, a method for producing a battery cell of an electrical energy store and a method for transmitting sensor data within a battery cell of an electrical energy store, in particular For use in electric vehicles, hybrid vehicles, and the like. Background technique [0002] With increasing demands, for example, on alternative drive concepts, especially electric drives are increasingly becoming the focus of consideration. Battery packs, which are used, for example, in the automotive industry generally consist of a plurality of modules, which in turn may consist of a plurality of lithium-ion cells, for example. The challenge in this case lies in particular in an efficient battery management system which can monitor the function of the individual cells of the battery and control the charging process of these cells. Furthermor...
