Abstract
The invention relates to a method for filling a hydrogen tank () of a motor vehicle () comprising a fuel cell drive, wherein the method comprises the steps: (a) determining a first operating time at which the motor vehicle () is to be started up and an expected first operating location at which the motor vehicle () is to be started up, (b) ascertaining a predicted maximum ambient temperature (T) at the first operating location at the first operating time, and (c) filling the hydrogen tank with hydrogen () until a tank pressure (p) in the hydrogen tank () reaches a maximum permissible tank pressure (p) at a tank temperature (T), wherein the following applies for the tank temperature (T): tank temperature (T)=[maximum ambient temperature (T); maximum ambient temperature (T)+10 K]. The invention relates further to a motor vehicle () comprising a hydrogen tank (), a fuel cell drive and a control system () for controlling filling of the hydrogen tank (), wherein the control system () to carry out the method.
