This electric construction machine is provided with: a drive system for driving a machine body by means of electric power; a heat exchange device that exchanges heat with a cooling medium for cooling the drive system; a cooling fan that conveys air that cools the heat exchange device; and a cooling fan control unit that controls the rotation of the cooling fan in accordance with the set operation mode. The operation mode includes a driving mode for driving the driving system and a charging mode for stopping driving of the driving system and charging a battery that accumulates power. The cooling fan control unit sets the rotation speed of the cooling fan in the charging mode to a charging mode rotation speed corresponding to the driving state of the driving system.
电动式建筑机械具备:驱动系统,其利用电力驱动机身;热交换装置,其对用于冷却驱动系统的冷却介质进行热交换;冷却风扇,其输送冷却热交换装置的空气;以及冷却风扇控制部,其根据已设定的动作模式来控制冷却风扇的旋转。上述动作模式包括驱动驱动系统的驱动模式、和使驱动系统的驱动停止而对蓄积电力的电池进行充电的充电模式。冷却风扇控制部将充电模式下的冷却风扇的转速设定为与驱动系统的驱动状态对应的充电模式转速。
