Ventilation shaft for battery module for traction of e.g. hybrid vehicle, has support for connecting intermediate section to module exit by connections allowing limited displacements of intermediate section with respect to exit of module

摘要

The shaft (12) has elastic bellows (16) connected to an air outlet of a module. An intermediate section (14) is connected with the bellows. A main section (24) is fixed on a case of a vehicle and connected to the intermediate section by a cabling system (22). A support connects the intermediate section to an exit of the module by connections i.e. connection stems, allowing small limited displacements of the intermediate section with respect to the exit of the module. An end of each connection stem crosses a drilling of an embossing of the exit of the module or the intermediate section.
