To provide an electrically-driven dump truck capable of reducing power consumption of a battery by effectively utilizing thermal energy.SOLUTION: An electrically-driven dump truck includes: a heat medium circulation circuit 200; an upstream selector valve V10; a return flow path intermediate valve V12; a bypass intermediate valve V22; and a controller 130. The heat medium circulation circuit 200 includes: a heat medium tank 201; a battery heat exchanger 202; a heat medium feed path 203; a heat medium return flow path 204; a fluid system heat exchanger 210; an electric system heat exchanger 220; a bypass 205; and an intermediate bypass 206. The controller 130 adjusts the temperatures of the heat medium by controlling open and close of the upstream selector valve V10, the return flow path intermediate valve V12 and the bypass intermediate valve V22, on the basis of a temperature T1 of the heat medium pooled in the heat medium tank 201, a temperature T2 of the heat medium at an exit of the battery heat exchanger 202, temperatures T3, T4 of fluid used for a fluid system device 110 and temperatures T5, T6 of an electric system device 120.SELECTED DRAWING: Figure 2

    【課題】本開示は、熱エネルギを有効利用することで、バッテリの消費電力を削減することが可能な電動ダンプトラックを提供する。【解決手段】電動ダンプトラックは、熱媒循環回路200と、上流切替弁V10と、還流路中間弁V12と、迂回路中間弁V22と、制御装置130とを備える。熱媒循環回路200は、熱媒タンク201と、バッテリ熱交換器202と、熱媒供給路203と、熱媒還流路204と、流体系熱交換器210と、電気系熱交換器220と、迂回路205と、中間バイパス206と、を備える。制御装置130は、熱媒タンク201に貯留された熱媒の温度T1、バッテリ熱交換器202の出口の熱媒の温度T2、流体系装置110に用いられる流体の温度T3,T4、および電気系装置120の温度T5,T6に基いて、上流切替弁V10、還流路中間弁V12、および迂回路中間弁V22の開閉を制御して、熱媒の温度を調節する。【選択図】図2
