Abstract

The invention provides a closed cabin system for the hydrogen safety test of a fuel cell vehicle. The closed cabin system comprises a closed cabin for parking a vehicle; and a gas exchange device anda test system capable of testing the hydrogen concentration are arranged inside the closed cabin and are connected with a control system. The closed cabin is provided with a sealing door for entranceor exit of a vehicle. With the provided closed cabin system, a problem of lack of a closed test device for simulating an actual parking space of a vehicle in the prior art is solved.

Description

technical field [0001] The invention belongs to the field of automobile fuel testing, and in particular relates to an airtight cabin system used for the hydrogen safety test of fuel cell automobiles. Background technique [0002] With the development of society, the pressure on the environment is increasing, and various energy-saving and emission-reduction technologies and products are constantly emerging. It is in this environment that hydrogen fuel cell vehicles have developed rapidly. Foreign auto companies such as Toyota, Honda, and Hyundai have already sold commercial vehicles, and domestic hydrogen fuel cell vehicles are also conducting demonstration operations. Since the hydrogen used in hydrogen fuel cell vehicles is a relatively dangerous flammable and explosive gas, it is necessary to ensure that the concentration of hydrogen emitted by vehicles meets safety requirements in actual use. At present, my country's national standard GB / T 24549-2009 "Safety Requirements...
