Abstract: The invention relates to a method for determining at least one state variable of the organism of at least one farm animal, wherein at least one probe device for measurement of at least one physical parameter is disposed in the gastro-intestinal tract of the farm animal and at least one evaluation unit is disposed outside the gastro-intestinal tract of the farm animal, characterized by the following steps: determining at least one first physical parameter by the probe device; converting the first physical parameter into a first state variable of the organism of the farm animal in a probe control unit of the probe device; transmitting the first state variable by the probe device to the evaluation unit; andconverting the first state variable into a second state variable in the evaluation unit. The invention further relates to a probe device for measuring at least one state variable of the organism of a farm animal as well as a system comprising at least one such probe device and an evaluation unit.

Abstract: A cell connection unit (CCU) for connecting a plurality of aligned battery cells of a battery module and a battery module including the CCU, the CCU including a plurality of busbars, each busbar of the plurality of busbars being connected to cell terminals of at least two battery cells of the plurality of aligned battery cells; and a plurality of carrier rails, at least some carrier rails of the plurality of carrier rails being mechanically connected to at least three busbars of the plurality of busbars, wherein the at least some carrier rails of the plurality of carrier rails include a first reception region connected to at least one busbar of the at least three busbars of the plurality of busbars, and a separate second reception region connected to two busbars of the at least three busbars of the plurality of busbars and electrically insulating the two busbars from each other.

Abstract: A cooling element to cool a component of a battery system, and a battery system having at least on cooling element. The cooling element includes a top cooling element part, a bottom cooling element part spatially under the top cooling element part, at least one cooling duct between the top cooling element part and the bottom cooling element part, and through which a cooling medium is to flow, and a Peltier element arranged resting against the bottom cooling element part so as to lie at least partially at the height of the at least one cooling duct.
