Abstract

The embodiment of the invention discloses a safety test system for a hydrogen storage tank of a hydrogen fuel cell, and the system comprises: a hydrogen storage tank support which is used for supporting a hydrogen storage tank clamp; a hydrogen storage tank which is used as a test object and is fixed through the hydrogen storage tank clamp; an impactor emitting device which is placed at a first set distance from the hydrogen storage tank and is used for emitting an impactor in a direction perpendicular to a battery pole plate; an impactor velocimeter which is used for monitoring the speed of the impactor in the launching process after the impactor is launched from the impactor exit port; a first camera which is placed at the position away from the hydrogen storage tank by a second set distance and used for recording the phenomenon of the hydrogen storage tank after the impactor penetrates the hydrogen storage tank, wherein the phenomenon is used for evaluating the safety level of the hydrogen storage tank when the hydrogen storage tank is shot by the impactor. By adopting the technical scheme, the test working condition that the hydrogen storage tank is shot by the impactor can be truly simulated, and the generated test result has good discrimination and repeatability.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a safety test system for a hydrogen storage tank of a hydrogen fuel cell. Background technique [0002] Hydrogen fuel cells have the advantages of high energy density, large discharge rate, low cost, and wide source of hydrogen, and are widely used in electric equipment, mobile power stations, and portable power supplies. With higher energy density and larger capacity, the safety of hydrogen fuel cells has attracted more and more attention, especially the high-pressure hydrogen storage tank of hydrogen fuel cells is the biggest safety hazard. Especially when hit by high-speed objects such as projectiles or fragments, it can cause fire, combustion or even explosion. Therefore, it is particularly important to construct a safety evaluation method for hydrogen fuel cell hydrogen storage tanks when they are shot, so as to guide the safety design of batteries and select safe batteri...
