The invention provides a charging pile system for realizing power battery fault diagnosis based on a cloud platform. The system comprises a charging pile, a cloud platform and a user APP, the chargingpile comprises a main control board, a 3/4/5G module, a WiFi module, a charging gun and a voltage measuring instrument, and the cloud platform comprises a user data receiving module, a signal noise reduction module, a characteristic parameter extraction module, a curve similarity degree calculation module and a fault diagnosis module; the charging pile acquires battery data of the power battery in the charging process in real time; the obtained data is transmitted o the signal noise reduction module through the 3/4/5G module or the WiFi module to obtain denoised battery data; and the noise-reduced battery data is input into the characteristic parameter extraction module to obtain a characteristic parameter curve, the obtained characteristic parameter curve is input into the curve similarity degree calculation module to obtain a charging cycle characteristic parameter curve similarity degree, and i the charging cycle characteristic parameter curve similarity degree is input into the fault diagnosis module in the cloud platform to judge whether a fault occurs or not.

    本发明提供一种基于云平台实现动力电池故障诊断的充电桩系统,包括充电桩、云平台和用户APP,所述充电桩包括主控板、3/4/5G模块、WiFi模块、充电枪、电压测量仪,云平台包括用户数据接收模块、信号降噪模块、特征参数提取模块、曲线相似程度计算模块、故障诊断模块;充电桩实时获取动力电池在充电过程中的电池数据;将所得数据通过3/4/5G模块或WiFi模块传至信号降噪模块得到降噪后的电池数据;将所得降噪后的电池数据输入特征参数提取模块,得到特征参数曲线,将所得的特征参数曲线输入曲线相似程度计算模块,得到该充电循环特征参数曲线相似程度,将其输入云平台中的故障诊断模块判断是否发生故障。
