The invention discloses an electric vehicle charging detection method, which comprises the following steps: taking the change of an active power transient waveform in a socket as a transient event, and monitoring the transient event based on a time sliding window; when the transient event is ended, calculating the variable quantity of the active power before and after the transient event; comparing the variable quantity of the active power with an active power threshold value of the electric vehicle to determine that the electric vehicle is inserted into the socket, and acquiring an active power sampling sequence in the socket in the time sliding window; processing the active power sampling sequence based on an electric vehicle charging detection model, and detecting the charging state of the electric vehicle; the detection accuracy of the charging state of the electric bicycle is improved, and the charging misjudgment event of the electric bicycle is avoided.

    本发明公开一种电动车充电检测方法,包括将插座中存在有功功率暂态波形的变化作为暂态事件,基于时间滑动窗口监测所述暂态事件;在所述暂态事件结束时,计算所述暂态事件发生前后有功功率的变化量;将所述有功功率的变化量与电动车有功功率阈值比较确定有电动车插入插座中时,采集所述时间滑动窗口内插座中的有功功率采样序列;基于电动车充电检测模型对所述有功功率采样序列进行处理,检测电动车充电状态;本发明提高电动车充电状态检测的准确性,避免了电动自行车充电误判事件的发生。
