Motor vehicle with a cryogenic pressure vessel and method for refueling a cryogenic pressure vessel of a motor vehicle

摘要

The technology disclosed herein relates to a method for refueling a cryogenic pressure vessel of a motor vehicle and a motor vehicle having a cryogenic pressure vessel. The motor vehicle comprises: a) a cryogenic pressure vessel 100 with a fluid storage inner container 110, an outer container 120 and a heat insulation V, which is at least partially disposed between the inner container 110 and the outer container 120; and b) a controller 140, wherein the controller 140 is configured to interrupt refueling of the motor vehicle when, in the event of damaged thermal insulation V, a lower fluid density limit value DUB for the fluid in the inner container 110 is exceeded, the lower fluid density limit value DUB being less than one upper fluid density limit value DOB for the fluid in the inner container 110 in the case of refueling of the inner container 110 with intact heat insulation V.
