The invention relates to an electric operation vehicle system, and belongs to the technical field of charging and discharging of electric vehicles. The electric operation vehicle system comprises an electric operation vehicle, the electric operation vehicle comprises a power battery and upper equipment, and the power battery is used for supplying power to enable the electric operation vehicle to run; the electric operation vehicle system further comprises an external power supply vehicle arranged on the rear portion of the electric operation vehicle, the external power supply vehicle comprises a vehicle body and an external battery fixedly arranged on the vehicle body, and the external battery is used for being connected with the upper equipment so as to supply power to the upper equipment. The running of the electric working vehicle depends on the power supply of the power battery, and the working of the top-mounted equipment depends on the power supply of the external battery, so that compared with the mode that the running of the electric working vehicle and the working of the top-mounted equipment take power from the power battery in the prior art, the running mileage of the electric working vehicle during working is increased, and the parking charging frequency is reduced.
本发明涉及一种电动作业车辆系统,属于电动车的充放电技术领域。电动作业车辆系统包括电动作业车辆,电动作业车辆包括动力电池以及上装设备,动力电池用于供电以使电动作业车辆行驶;电动作业车辆系统还包括设于电动作业车辆后部的外配电源车,外配电源车包括车体以及固设于车体上的外配电池,外配电池用于与上装设备相连,以向上装设备供电。电动作业车辆的行驶依靠动力电池供电,上装设备的工作依靠外配电池供电,相比现有技术中电动作业车辆的行驶、上装设备的工作均自动力电池处取电的方式而言,电动作业车辆在作业时的行驶里程得以增加,降低了停车充电的频率。
