FCフォークリフト5は、事業所内で運用される産業用の燃料電池車両であり、非公道を走行する。図1では図示を省略したが、FCフォークリフト5は、水素タンク(燃料タンク)と、通信手段と、を備えている。通信手段は、水素タンクの水素の残量データを、ネットワークNWを介して管理装置1に定期的に送信する。
次に、水素供給システムによる水素供給方法について、図2を参照しながら説明する。まず水素充填装置2は、カードル4に水素を充填する(ステップS1)。続いて、図示しない積載手段(例えばフォークリフト)を利用して、輸送車両3の荷台に水素充填済みのカードル4を積載する(ステップS2)。
R(T):事業所で利用可能なT時間後の水素の残量
αi(t):残量予測部111が定期的に受信した、i番目のカードル4の水素残量補正比
Ci:i番目のカードル4の水素貯蓄量
FCi:i番目のFCフォークリフト5の水素貯蓄量
βi(t):残量予測部111が定期的に受信した、i番目のFCフォークリフト5の水素残量補正比
Xi:i番目のFCフォークリフト5の単位時間当たりの消費水素量
Ci:一番目のカードル4の水素貯蓄量=10kg
FC1:一番目のFCフォークリフト5の水素貯蓄量=1kg
FC2:二番目のFCフォークリフト5の水素貯蓄量=1kg
β1(t):残量予測部111が時間tに受信した、一番目のFCフォークリフト5の水素残量補正比=0.2
β2(t):残量予測部111が時間tに受信した、二番目のFCフォークリフト5の水素残量補正比=0.5
X1:一番目のFCフォークリフト5の一時間当たりの消費水素量=0.2kg/h
X2:二番目のFCフォークリフト5の一時間当たりの消費水素量=0.4kg/h
R(1)=0.8×10kg-{1kg(1-0.2)+0.2kg}-1kg{1kg(1-0.5)+0.4kg}=8kg-1kg-0.9kg=6.1kg
