    Abstract: During travel of the electric vehicle, the charging arm is extended in the vehicle width direction, a positive electrode overhead line of the power supply device and a positive electrode power reception unit of the charging arm are brought into contact at the same time that a negative electrode overhead line of the power supply device and a negative electrode power reception unit of the charging arm are brought into contact, and a power storage device for driving the electric vehicle is charged. A charging head that is the tip section of the charging arm is held within a V-shaped groove to which the positive electrode overhead line and the negative electrode overhead line are attached, thereby minimizing the loss of contact even if the charging arm shakes in the vertical direction as a result of the condition of the road surface, brake operation, or the like.

    Abstract translation: 在电动汽车行驶期间,充电臂在车宽方向上延伸,电源装置的正极架空线和充电臂的正极电力接收单元同时接触负极 电源装置的电极架空线和充电臂的负极电力接收单元接触,并且用于驱动电动车辆的蓄电装置被充电。 作为充电臂的前端部的充电头保持在安装有正极架空线和负极架空线的V字形槽内,从而尽可能减少接触损失,即使充电臂在 作为路面,制动操作等的状况的垂直方向。

    Abstract: An electric power supply device supplies electric power to a work machine having an electric power source. The electric power supply device includes a fuel cell different from the electric power source and an electric power connecting section for transferring electric power between the electric power source and the electric power supply device. A control device for controlling the electric power supply device includes a rated capability obtaining section for obtaining the information indicating the rated value of the charge and discharge capability of the electric power source of the work machine in response to the electric power supply device being mounted in the work machine or the electric power supply device being able to utilize the electric power of the electric power source, and an operating condition determining section for determining the operating condition of the electric power supply device based on the rated value.
