Liquid Hydrogen Tank Control Device and Control Method Thereof

A method of controlling a liquid hydrogen tank using a liquid hydrogen tank control device,

• wherein the liquid hydrogen tank control device comprises:
• a plurality of temperature sensors provided at different heights from each other on an outer surface of an inner tank located inside an outer tank of the liquid hydrogen tank;
• at least one pressure sensor configured to measure pressure of a storage space in which liquid hydrogen in the inner tank is stored;
• and
• a control board capable of wireless communication and measuring a level of liquid hydrogen stored in the storage space of the inner tank based on a plurality of temperature values measured by the plurality of temperature sensors,
• wherein the method comprises:
• determining a level of liquid hydrogen in the inner tank based on the temperature values measured by the plurality of temperature sensors;
• and
• determining whether pressure in the inner tank is within an appropriate pressure range based on pressure values measured by the pressure sensor.
