Battery cabinet with baffle arrangement, baffle arrangement for a battery cabinet and method for operating a battery cabinet

摘要

A battery cabinet (100) having a battery chamber (90) with a battery rack (95), in operation, battery cell groups (10, 20, 30, 40, 50, 60) in a number of battery levels vertically with a vertical cell spacing (A) on top of each other and the individual cells are arranged at a horizontal distance, a battery cabinet door (80) for opening and in particular hermetically closing the battery chamber (90), a cooling system (70) disposed in the battery cabinet door (80) and having a fan (75) the battery cabinet (100) has a arranged on the battery cabinet door baffle arrangement (200) with inlet openings (215, 225, 235, 245, 255), which are designed to divide a generated by the fan main air volume flow (ZV) in a number of in Substantially equal partial volume flows (VT1, VT2, VT3, VT4, VT5, VT6) and for directing these partial volume flows towards a respective battery cell group (10, 20, 30, 40, 50, 60) in order to specifically flow to the battery cell groups (10, 20, 30, 40, 50, 60) by means of the respective partial volume flows and thus to obtain a spatially homogeneous temperature distribution over the battery cell groups, preferably with a deviation of less than 3 Kelvin, a free space (300) is provided between the baffle arrangement (200) and all battery levels, into which the part volume flows open and which is open to all battery cell groups (10, 20, 30, 40, 50, 60).
