Abstract (en)

[origin: CA2911197A1] The invention relates to a method for determining a tank pressure (12) in a tank (5) before the tank (5) is filled with pressurised, gaseous hydrogen, according to which method an accumulator (1), in which the hydrogen to be used to fill the tank is stored as liquid hydrogen, is connected to the tank (5) by means of a filling line (2) and a subsequent check valve (4) of the tank (5), wherein hydrogen is pumped from the accumulator (1) into the filling line (2) by means of a pump (3) and the filling-line pressure (11) arising in the filling line (2) during the pumping is measured, wherein the check valve (4) is opened if the filling-line pressure (11) exceeds the tank pressure (12), and wherein the tank pressure (12) is determined as the filling-line pressure (11) that exists when the check valve (4) is opened.
