Abstract: The present invention relates to a drive assembly (10) for a manually driven vehicle (80), in particular a bicycle or a pedelec, with an electric auxiliary drive (24), wherein the drive assembly (10) has a first drive shaft (12) for a manual drive and a rotor (20) of the electric auxiliary drive (24), and wherein the first drive shaft (12) and the rotor (20) of the electric auxiliary drive (24) are coupled to a common drive element (29), wherein the first drive shaft (12) and the rotor (20) of the electric auxiliary drive (24) are coupled to the drive element (29) by means of a harmonic drive (25), wherein the harmonic drive (25) has an outer sleeve (28) with an internal toothing system (62) and a deformable inner sleeve (26) with an external toothing system (64) and a shaft generator (27), wherein the shaft generator (27) is at least indirectly connected fixedly to the rotor (20) of the electric auxiliary drive (24) so as to rotate with it, wherein the deformable inner sleeve (26) is at least indirectly conn

Abstract: A battery pack having at least one battery cell, wherein the battery cell is coupled and electrically conductively connected to connecting elements at its battery poles, is configured and developed in respect of simplified production with simple structural means in such a way that the battery cell is positioned on a flat conductor element and that the battery cell is electrically conductively connected to the conductor element by a separating process and/or a shaping process between connecting elements and conductor element and is fixed to or on the conductor element.

Abstract: The present invention relates to a supply network component for a supply network for a network medium, comprising at least one contact unit for contacting a further supply network component of the supply network, a functional group having at least one functional unit, and at least one coupling unit for coupling the at least one contact unit to the functional group, wherein the at least one contact unit has a communication interface for communicating with a further supply network component of the supply network and a transport interface for transporting the network medium to a further supply network component. The present invention furthermore relates to an energy storage block comprising a plurality of the proposed supply network components.
