Vehicle having a plurality of storage vessels for a combustible gas, and method for displaying the available stored quantity and controlling the extraction

摘要

The present invention relates to a vehicle (2) having a drive (4) for a combustible gas, in particular hydrogen, and a plurality of storage vessels (6) for a combustible gas which are connected to the gas drive (4) via a connector. In order to provide a simple possibility of determining at least approximately accurately the still present residual quantity of a combustible gas which is available for the operation of the vehicle, it is proposed that a plurality of storage vessels (6) are connected to the vehicle (2), wherein each storage vessel (6) has a connection piece (8), by way of which it can be connected to the vehicle-side connector (10) mechanically and in a pressure-resistant manner, and the vehicle (2) has an electronic controller (16), by which the number of storage vessels (6) which are connected to the vehicle (2) and the presence of combustible gas in the respective storage vessels (6) can be determined via sensors, and the electronic controller (16) transmits a quantity signal about the gas quantity which is still available from the storage vessels (6) to a supply display (18) which is present in the vehicle (2), wherein the magnitude of the quantity signal is dependent on the number of storage vessels (6) which have been detected as being connected to the vehicle (2) and filled.
