Abstract

The invention relates to a battery holder (1) for galvanic cells, in which a first honeycomb structure (2.1 to 2.n), comprising a lower and an upper basic cooling body (3.1, 3.2) and at least one intermediate cooling body (4), is provided, wherein in each case, galvanic cells can be arranged on a cell level (5.1 to 5.n) in each case between one of the basic cooling bodies (3.1, 3.2) and one of the intermediate cooling bodies (4) and/or between two of the intermediate cooling bodies (4), wherein the galvanic cells of one of the cell levels (5.1 to 5.n) are displaced to the side to the galvanic cells of at least one adjacent cell level (5.1 to 5.n) by half the width of a galvanic cell, and wherein the intermediate cooling body (4) and the basic cooling bodies (3.1, 3.2) 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 (3.1, 3.2, 4) comprises at least on one end which lies in an axial direction to the galvanic cells a cooling chamber (8), 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 cooli…
