PROBLEM TO BE SOLVED: To appropriately calculate timing of resource supply by more appropriately estimating resource consumption of a work vehicle on a specific work site.SOLUTION: The present invention relates to a resource supply system for a work vehicle performing work travel on a work site while consuming resources supplied from an energy source pack mounted in a vehicle body. The resource supply system comprises: a consumption recording part 62 for recording actual unit consumption of resources as a work history together with a work content； a work schedule management part 52 for managing work schedule information including the work content； an estimated consumption calculation part 101 for calculating estimated unit consumption of resources to be consumed per unit work amount of the work vehicle implemented based on the work schedule information while referring to the work history； and a supply management part 60 for calculating supply timing in which resources are supplied to the energy source pack, based on the estimated unit consumption.SELECTED DRAWING: Figure 1【課題】特定作業地における作業車の資源消費がより適切に推定され、適切に資源補給のタイミングが算出されること。【解決手段】車体に搭載されたエネルギ源パックから供給される資源を消費しながら作業地で作業走行を行う作業車のための資源補給システムが資源の実単位消費量を作業内容とともに作業履歴として記録する消費量記録部６２と、作業内容を含む作業計画情報を管理する作業計画管理部５２と、作業計画情報に基づいて実施される作業車の単位作業量あたりに消費される資源の推定単位消費量を、作業履歴を参照して算出する推定消費量算出部１０１と、推定単位消費量に基づいてエネルギ源パックに資源を補給する補給タイミングを算出する補給管理部６０を備えている。【選択図】図１
