The invention discloses a battery replacing method and system for an electric vehicle and a battery replacing station. The method comprises the steps that image analysis data of a battery of the electric vehicle is obtained at the battery replacing station of the electric vehicle; analyzing the image analysis data by using a first detection model obtained based on abnormal battery sample image training so as to judge whether a preset type of surface defect exists on the outer surface of the battery; if the outer surface of the battery does not have the surface defect, analyzing the image analysis data by using a second detection model obtained based on normal battery sample image training so as to judge whether the image analysis data has a preset type of surface difference; and if the image analysis data does not have the surface difference, replacing the battery of the electric vehicle. The first detection model and the second detection model are sequentially used in the battery swap station to detect the battery, and compared with manual detection and traditional AI detection, the detection accuracy is improved, and the cost is reduced.

    本申请公开了一种电动车辆换电方法、系统及换电站,包括:在电动车辆的换电站获取所述电动车辆的电池的图像分析数据;使用基于异常电池样本图像训练得到的第一检测模型对所述图像分析数据进行分析,以判断所述电池的外表面是否存在预设类型的表面缺陷;若所述电池的外表面不存在所述表面缺陷,则使用基于正常电池样本图像训练得到的第二检测模型对所述图像分析数据进行分析,以判断所述图像分析数据是否存在预设类型的表面差异;若所述图像分析数据不存在所述表面差异,则对所述电动车辆的电池进行更换。本发明通过在换电站中依次使用第一检测模型和第二检测模型对电池进行检测,相较于人工检测及传统的AI检测,提高了检测准确度,降低了成本。
