1. A hydrogen storage system comprising:
a detection device configured to detect a first hydrogen pressure decompressed by a regulator using a first pressure sensor in the hydrogen storage system; and
a processor configured to predict generation of noise at the regulator based on a change rate of the first hydrogen pressure during hydrogen charging, and to stop the hydrogen charging;
wherein the processor is further configured to:
classify a charging state into at least two or more steps depending on the first hydrogen pressure;
calculate a first hydrogen pressure slope during a time different for each classified charging state;
compare the calculated first hydrogen pressure slope with a reference pressure slope matching the classified charging state; and
transmit a charging stop signal when the calculated first hydrogen pressure slope is not less than the reference pressure slope matching the classified charging state.
