Abstract：Thechargingdataofelectricvehiclechargingfacilitiesincludesvoltage，current，temperature，power，etc.allof whicharetimeseriesdata，andthedatahasthecharacteristicsofinfluencingtheprevioustimeandasociatingthenexttime. Thelongshort-termmemory（LSTM）neuralnetworkisusedtominethecorelationfeaturesinthedatavolume，andthefeature modelbetweentheworkingdataandthefaultisestablishedtoconductthefaultdiagnosisofchargingpile.Duetotheproblems ofoverfitingandgetingstuck inlocaloptimainLSTMneuralnetworks，ageneticalgorithm（GA）isproposed tooptimizethe LSTMneuralnetwork forfaultdiagnosisofcharging piles.GAisusedtosearch fortheoptimal solutionbysimulating the biologicalevolutionprocessindividualswithhighfiessareselectedforeproduction，andmutationoperationsareintroducedt graduallyoptimizethecombinationofhyperparameters，soastoimprovetheperformanceandeficiencyoftheLSTMmodel.In comparison with the experimental resultsof LSTMneural network，the RMSEvalueand MPAEvalueof GA-LSTM neural network prediction results are decreased by 56.7% and 60.3% ，respectively，and the accuracy rate of fault diagnosis is increased by 3.2% .Therefore，GA-LSTMneural network can beusedasa dep learning technologyforthe fault diagnosis of charging pile.
