The invention relates to the technical field of wireless charging, and discloses an electric bicycle wireless charging method and system, and the method comprises the steps: converting an access power supply into an alternating current with a preset frequency; the alternating current is connected to a transmitting coil to generate an alternating electromagnetic field; the electric bicycle entering the charging area is charged through the alternating electromagnetic field; performing real-time sensor detection on the environment in the charging area to obtain real-time sensor data; establishing an FOD detection model, obtaining a relationship between sensor data and foreign matters through deep learning of a historical sensor data set, and judging whether the foreign matters exist in the charging area or not according to real-time sensor data; controlling the power supply of the transmitting coil according to the foreign matter judgment result of the FOD detection model; and when the foreign matter is detected in the charging area, the power supply of the transmitting coil is cut off. According to the method and the system, the foreign matter detection accuracy is improved, the omission ratio is reduced, the foreign matter detection requirements in a complex environment can be met, and intelligent charging management is realized.

    本发明涉及无线充电技术领域,公开一种电动自行车无线充电方法及系统,包括将接入电源转换成预定频率的交变电流;将交变电流接入发射线圈,以产生交变电磁场;通过交变电磁场对进入充电区域内的电动自行车进行充电;对充电区域内的环境进行实时传感器检测,获得实时传感器数据;建立FOD检测模型,通过深度学习历史传感器数据集获得传感器数据与异物之间的关系,并根据实时传感器数据判定充电区域内是否存在异物;根据FOD检测模型的异物判定结果控制发射线圈的供电;当检测到充电区域内存在异物时,切断发射线圈的供电。本发明的方法及系统,提高异物检测准确率、降低漏检率,能够适应复杂环境下的异物检测需求,实现智能化的充电管理。
