VENTILATION AND SEPARATION DEVICE FOR HOUSING OF BATTERY

The invention relates to a ventilation and separation device (100) for a housing (50) of a battery, in particular a traction battery of a motor vehicle, comprising a base body (10) having a circumferentially extending edge (12) provided for coupling to the housing (50), where the base body (10) comprises at least one inlet opening (14) and at least one outlet opening (18), where the at least one inlet opening (14) and the at least one outlet opening (18) are connected to the housing (50). The base body (10) comprises at least a first separating screen (20) having first screen holes (22) and engaging across the inlet opening (14), and a second separating screen (30) having second screen holes (32) and engaging across the outlet opening (18) in the ventilation flow direction (24) downstream of the fluid of the first separating screen (20). The ventilation and separation device (100) includes at least one pressure relief valve (40) configured to open a bypass fluid flow path (26) from an interior (58) of the hou
