Abstract
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 ΔPcan 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 ΔPcan be provided as a flow restrictor on the side of the hydrogen tank having smaller heat flux, wherein ΔP>ΔP.
