The invention discloses a fault early warning method for a new energy automobile battery swap station, and belongs to the technical field of new energy battery swap stations, and the method specifically comprises the following steps: identifying and uploading unique identification codes of a vehicle, a used battery pack and a to-be-used battery pack; bolt locking and unlocking data of a used battery pack or a to-be-used battery pack of the vehicle in the battery replacement process of the vehicle are confirmed and uploaded to a data center monitoring system, and standard values of the number of locking turns, the locking torque, the number of cap recognition times and the number of unlocking times are set; when any value of the number of locking turns or locking torque of the used battery pack or the to-be-used battery pack is smaller than a standard value, early warning recording is carried out, and when any value of the number of cap recognition times and the number of unlocking times of the used battery pack or the to-be-used battery pack is smaller than the standard value, early warning recording is carried out; and alarming. According to the invention, data of the battery pack is checked, so that the defect that an existing battery swap station system only carries out fault detection on each mechanism of the battery swap station is overcome.

    本发明公开了一种新能源汽车换电站的故障预警方法,属于新能源换电站技术领域,具体包括以下内容:识别并上传车辆、已使用电池包和待使用电池包的唯一识别码,确认并上传车辆换电过程中车已使用电池包或待使用电池包的螺栓加加解锁数据至数据中心监控系统,设定加锁圈数、加锁扭矩、认帽次数和解锁次数的标准值,在已使用电池包或待使用电池包加锁圈数或加锁扭矩的任一数值小于标准值时进行预警记录,在已使用电池包或待使用电池包认帽次数和解锁次数的任一数值小于标准值时进行预警记录,当任一数值记录次数大于设定次数n时,进行报警。本发明通过对电池包的数据进行检查,补全了现有换电站系统仅对换电站各机构进行故障检测的短板。
