Hydrogen tank system and diagnostic method for a hydrogen tank system

Abstract

The invention relates to a diagnostic method (100) for a medium pressure region of a hydrogen tank system (200), wherein the diagnostic method (100) comprises: determining (101) a first pressure present in a medium pressure region of the hydrogen tank system (200) by means of a first pressure sensor (205) arranged at the medium pressure region, determining (103) a difference between the first pressure and a reference pressure determined by a second pressure sensor, comparing (105) the difference with a predetermined threshold value, storing (107) a result of the comparison in a memory at least in the event that the difference deviates from the threshold value.
