Abstract
A liquid hydrogen tank control device is capable of wireless communication. A control board measures a level of liquid hydrogen stored in a storage space of an inner tank of a liquid hydrogen tank based on a plurality of temperature values measured by a plurality of temperature sensors located at different heights from each other on an outer surface of the inner tank located inside an outer tank of the liquid hydrogen tank.
Claims8
A liquid hydrogen tank control device comprising:
- a control board capable of wireless communication and measuring a level of liquid hydrogen stored in a storage space of an inner tank of a liquid hydrogen tank based on a plurality of temperature values measured by a plurality of temperature sensors provided at different heights from each other on an outer surface of the inner tank located inside an outer tank of the liquid hydrogen tank,
- wherein the control board is configured to:
- control On/Off of an opening/closing valve provided in a gas discharge pipe connected to the liquid hydrogen tank through a wireless communication module,
- control an electrical output of a fuel cell through the wireless communication module, and
- control On/Off of a heater through the wireless communication module.

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;
- determining whether pressure in the inner tank is within an appropriate pressure range based on pressure values measured by the pressure sensor;
- and
- controlling On/Off of an opening/closing valve provided in a gas discharge pipe connected to the liquid hydrogen tank, electrical output of a fuel cell, and a heater through a wireless communication module of the control board.
