Disclosed is a liquid hydrogen filling system and a filling method comprising a liquid hydrogen storage tank. The liquid hydrogen filling system according to the present invention divides the inner tank of the liquid hydrogen storage tank into a first inner tank and a second inner tank provided in independent spaces, and the pressure between the first inner tank and the second inner tank is mutually divided. By using a car to easily flow liquid hydrogen from a liquid hydrogen storage tank into a high pressure pump, it is possible to charge high pressure of liquid hydrogen having low specific gravity. |
