一种充电桩健康状态诊断方法及装置
摘要：
本发明涉及一种充电桩健康状态诊断方法及装置，包括根据充电桩异常发生时刻及异常发生时刻之前历史时刻的输出电压和输出电流，确定充电桩异常发生时刻及异常发生时刻之前历史时刻的健康系数；根据所述充电桩异常发生时刻及异常发生时刻之前历史时刻的健康系数，预测充电桩异常发生时刻之后未来时刻的健康系数；根据所述充电桩异常发生时刻及异常发生时刻之后未来时刻的健康系数，确定充电桩异常发生时刻的健康状态；本发明的技术方案缩短了充电桩异常的发现时间，提高了确定充电桩健康状态诊断结果的准确度。
摘要（英）：

The invention relates to a method and a device for diagnosing the health state of a charging pile. The method comprises the following steps of determining health coefficients of a charging pile at anabnormal occurrence time and a historical moment before the abnormal occurrence time according to output voltage and output current of the charging pile at the abnormal occurrence time and the historical time before the abnormal occurrence time; predicting a health coefficient of the charging pile at a future moment after the abnormal occurrence moment according to output voltage and output current of the charging pile at the abnormal occurrence time and the historical time before the abnormal occurrence time; and determining a health state of the charging pile at the abnormal occurrence moment according to output voltage and output current of the charging pile at the abnormal occurrence time and the future time after the abnormal occurrence moment. According to the technical scheme of theinvention, the finding time of an abnormity of a charging pile is shortened, and the accuracy of a health state diagnosis result of the charging pile is improved.
