Document Type and Number:
WIPO Patent Application WO/2019/229806
Kind Code:
A1
Abstract:
A power transmission device (300) comprises: a movable part (12) that rises and drops with respect to the ground; and an elevating mechanism (17) that raises and lowers the movable part (12). This defrosting method for the power transmission device measures the temperature of the power transmission device (300), compares the measured temperature with a preset threshold value for judging freezing of the power transmission device (300), and judges whether or not the power transmission device (300) is frozen. The defrosting method of the power transmission device excites a power transmission coil (41) when it is judged that the power transmission device (300) is frozen.
