本申请涉及充电桩技术领域,提供了充电桩过流故障报警方法、设备及存储介质。故障报警方法,包括:基于本次充电对应的充电配置信息确定用户限流值;基于目标充电桩的设备限流值以及用户限流值确定本次使用的动态限流值;在动态限流值大于均衡限流值且监测到输出电流大于或等于均衡限流值的情况下,确定输出电流是否小于动态限流值;在输出电流小于动态限流值的情况下,开始记录等待时长,直至输出电流小于均衡限流值;在等待时长大于或等于等待时长阈值的情况下,确定目标充电桩存在过流故障。通过采用上述技术方案,可以通过动态限流值和均衡限流值区分过流的场景,从而对不同的场景采用不同的报警触发策略,如此可以提高限流报警的准确性。

    The invention relates to the technical field of charging piles, and provides a charging pile overcurrent fault alarm method and device, and a storage medium. The fault alarm method comprises the following steps: determining a user current limiting value based on charging configuration information corresponding to current charging; determining a dynamic current-limiting value used this time based on the equipment current-limiting value and the user current-limiting value of the target charging pile; when the dynamic current limiting value is greater than the balanced current limiting value and the output current is monitored to be greater than or equal to the balanced current limiting value, determining whether the output current is less than the dynamic current limiting value; when the output current is smaller than the dynamic current-limiting value, starting to record the waiting time until the output current is smaller than the balanced current-limiting value; and under the condition that the waiting duration is greater than or equal to the waiting duration threshold value, determining that the target charging pile has an overcurrent fault. By adopting the technical scheme, the overcurrent scene can be distinguished through the dynamic current limiting value and the balanced current limiting value, so that different alarm triggering strategies are adopted for different scenes, and the accuracy of current limiting alarm can be improved.
