The invention relates to an electric wheel mining dump truck, in particular to a power control system of a new energy electric wheel mining dump truck. The defects and problems existing in an electricwheel mining dump truck which adopts a diesel generator set to provide power are solved. The power control system of the new energy electric wheel mining dump truck comprises a lithium battery, a hydrogen fuel cell engine, a direct-current bus, a first DC/DC triple chopper, a second DC/DC triple chopper and a third DC/DC triple chopper, wherein the lithium battery and the hydrogen fuel cell engine are respectively connected in parallel with the direct-current bus; the first DC/DC triple chopper takes power from the direct-current bus and supplies power to an armature winding of the first DC motor; the second DC/DC triple chopper takes power from the direct-current bus and supplies power to the armature winding of the second DC motor, and the third DC/DC triple chopper takes power from thedirect-current bus and supplies power to the excitation windings of the first DC motor and the second DC motor. The power control system adopts a hydrogen fuel engine and lithium battery hybrid energy system to replace the diesel generator set to provide power.

    本发明涉及电动轮矿用自卸车,具体为新能源电动轮矿用自卸车动力控制系统。解决电动轮矿用自卸车采用柴油发电机组动力存在的缺陷和问题。新能源电动轮矿用自卸车动力控制系统包括锂电池、氢燃料电池发动机、直流母线、第一DC/DC三重斩波器、第二DC/DC三重斩波器、第三DC/DC三重斩波器,锂电池和氢燃料电池发动机分别并联于直流母线,第一DC/DC三重斩波器从直流母线取电并为第一直流电动机的电枢绕组供电,第二DC/DC三重斩波器从直流母线取电并为第二直流电动机的电枢绕组供电,第三DC/DC三重斩波器从直流母线取电并为第一直流电动机和第二直流电动机的励磁绕组供电。该动力控制系统采用氢燃料发动机和锂电池混合能源系统替代柴油发电机组提供动力。
