To provide a charging system of work machine which can efficiently perform charging work of a battery of a work machine.SOLUTION: A charging system of work machine includes a plurality of drones 100, a hydraulic shovel 200, and a drone base 300. A controller 217 of the hydraulic shovel 200 estimates a power consumption amount accompanying a flight in which each drone 100 comes to the hydraulic shovel 200 and returns to the drone base 300 and power supply to a battery 210, in the case where a power storage amount of the battery 210 of the hydraulic shovel 200 is equal to or less than a predetermined threshold value. The controller 217 selects one drone 100 based on a preset condition out of the plurality of drones 100 in which the power storage amount of the battery 101 is larger than the power consumption amount, and transmits a power supply command to the selected drone 100.SELECTED DRAWING: Figure 2

    【課題】作業機械のバッテリの充電作業を効率よく行うことができる作業機械の充電システムを提供する。【解決手段】作業機械の充電システムは、複数のドローン100と、油圧ショベル200と、ドローン基地300とを備える。油圧ショベル200のコントローラ217は、油圧ショベル200のバッテリ210の蓄電量が所定の閾値以下である場合に、各ドローン100が油圧ショベル200へ来てドローン基地300に帰還するまでの飛行とバッテリ210への給電に伴う消費電量を推定する。コントローラ217は、バッテリ101の蓄電量が消費電量より大きい複数のドローン100から、予め設定された条件に基づいて1つのドローン100を選択し、選択したドローン100に給電指令を送信する。【選択図】図2
