PROBLEM TO BE SOLVED: To provide a hydrogen charging method and a hydrogen station capable of charging hydrogen more efficiently to an object to be charged.SOLUTION: At a hydrogen station 100, hydrogen stored at an accumulator part 6 is charged under a differential pressure if residual pressure at a hydrogen fuel automobile M1 is higher than a pre-set threshold. When the residual pressure at the hydrogen fuel automobile M1 is high, its charging amount is less and the charging can be carried out within a short period of time. Accordingly, as for the hydrogen fuel automobile M1, a fast hydrogen charging assuring a superior fast charging function can be performed through a pressure differential charging. In addition, if the residual pressure in the hydrogen fuel automobile M2 is equal to or less than a prescribed set threshold, hydrogen in which pressure has been already increased at the second pressure increasing part 4 is directly charged at a hydrogen fuel automobile M2. When the residual pressure at the hydrogen fuel automobile M2 is low, it is necessary to keep a large amount of hydrogen for charging and perform longer hour charging operation. Accordingly, as for the hydrogen fuel automobile M2, the second pressure increasing part 4 is used and a direct charging with superior persistence is carried out.SELECTED DRAWING: Figure 2

    【課題】充填対象に対して効率よく水素を充填することができる水素充填方法、及び水素ステーションを提供する。【解決手段】水素ステーション100では、水素燃料自動車M1の残圧が予め設定された閾値より高い場合には、蓄圧部6に貯蔵された水素が充填対象に差圧充填される。水素燃料自動車M1の残圧が高い場合は、充填量も少なく、短時間で充填を行うことが可能である。従って、残圧の高い水素燃料自動車M1に対しては、瞬発力に優れた差圧充填により速やかに充填を行うことができる。また、水素燃料自動車M2の残圧が予め設定された閾値以下である場合には、第2の昇圧部4で昇圧された水素が水素燃料自動車M2に直充填される。水素燃料自動車M2の残圧が低い場合は、充填量が多く、長時間の充填が必要である。従って、残圧の低い水素燃料自動車M2に対しては、第2の昇圧部4を用い、持続力に優れた直充填を行う。【選択図】図2
