A hydrogen filling system includes: a hydrogen tank that is filled with hydrogen; a determination unit that determines whether to fill hydrogen into the hydrogen tank; and a temperature regulating unit that regulates a temperature of the hydrogen tank, wherein, when the determination unit determines to fill hydrogen into the hydrogen tank, the temperature regulating unit starts cooling the hydrogen tank before filling of hydrogen into the hydrogen tank is started.

Hydrogen filling system and hydrogen filling method

A system for hydrogen charging has an orifice provided as a flow restrictor between a hydrogen charging port and a hydrogen tank having a larger heat flux value. No orifice is provided on the side of a hydrogen tank having a smaller heat flux value. The orifice has a function of increasing the channel resistance. With the above, it is possible to initially have the hydrogen tank having a smaller heat flux value in the fully charged state, and thereafter the hydrogen tank having a larger heat flux value in the fully charged state. Alternatively, a check valve having a cracking pressure &#x394;Pcan be provided as a flow restrictor on the side of the hydrogen tank having larger heat flux, and a check valve having a cracking pressure &#x394;Pcan be provided as a flow restrictor on the side of the hydrogen tank having smaller heat flux, wherein &#x394;P&#x3e;&#x394;P.
