Abstract: A method for testing a software application and data related to the software application of a vehicle includes receiving a first vehicle configuration and a test parameter, the test parameter comprising a technical property of the first vehicle configuration. The method further includes specifying a setpoint value for the received test parameter, determining a first software identifier as a function of the first vehicle configuration, and specifying the software application and the data related to the software application by means of the first software identifier. The method also includes determining an actual value for the received test parameter using the specified software application or the specified data related to the software application, testing whether the determined actual value of the received test parameter and the determined setpoint value of the received test parameter match, and providing a test result of the received test parameter as a function of the test.

Abstract: A fuel supply system for an internal combustion engine operable using hydrogen and/or for a fuel cell includes a hydrogen tank, which is provided for storing deep-cooled, liquid hydrogen, and a heat exchanger, which is provided for preheating the deep-cooled hydrogen. The heat exchanger is enclosed by a fluid-tight mantle. An intermediate space is provided between the heat exchanger and the mantle, which has a fluid flowing through it, which delivers heat to the heat exchanger and insulates the heat exchanger in relation to the surroundings.
