Various embodiments include a guide ring for connection to a housing of an electric machine comprising: a main body having a ring element; a plurality of busbars; and a plurality of pressure elements. The busbars are overmolded by the main body. Each of the plurality of pressure elements projects from an outer circumferential surface of the main body and to frictionally connect the guide ring to an inner receiving surface of the housing.

Guide ring for connection to a housing of an electric machine

The invention relates to a battery holder () for galvanic cells, in which a first honeycomb structure (to), comprising a lower and an upper basic cooling body () and at least one intermediate cooling body (), is provided, wherein in each case, galvanic cells can be arranged on a cell level (to) in each case between one of the basic cooling bodies () and one of the intermediate cooling bodies () and/or between two of the intermediate cooling bodies (), wherein the galvanic cells of one of the cell levels (to) are displaced to the side to the galvanic cells of at least one adjacent cell level (to) by half the width of a galvanic cell, and wherein the intermediate cooling body () and the basic cooling bodies () are formed in an area between the galvanic cells according to the outer contours of the galvanic cells, and wherein each of the cooling bodies () comprises at least on one end which lies in an axial direction to the galvanic cells a cooling chamber (), through which a cooling medium (K) can flow, into which the cooling medium (K) can flow from at least one cooling chamber (K) of at least one adjacent cooling body () and/or from which the cooling medium (K) can flow out into at least one cooling chamber () of at least one of the adjacent cooling bodies (), wherein at least one cooling chamber () of at least one of the cooling bodies () comprises a cooling agent inflow () and/or a cooling agent outflow ().

Method and device for determining the ageing of a battery

A device for joining and storing energy storage cells having a flexible envelope and which are arranged in a rigid housing having a window opening on a planar side thereof and two openings for the metallic current leads of the energy storage cell. The device includes a sheet metal frame in which the energy storage cells are inserted and in which a heat sink is arranged.
