And when the charging interface voltage does not meet the charging interface voltage range or the charging interface temperature does not meet the interface temperature range, the target vehicle initiates a fault positioning request to the vehicle charging data platform, and simultaneously generates fault request information by charging interface attribute information, a fault vehicle identifier and a charging pile number.

And S230, sending the fault request information to the cloud platform so that the cloud platform determines the use state information of the charging pile corresponding to the charging pile number according to the received fault request information, and feeding back the use state information to the target vehicle so that the target vehicle determines the target charging fault information.

Otherwise, the vehicle charging data cloud platform judges whether the target vehicle sends a fault location request, if so, the vehicle charging data cloud platform inquires the information table, specifically, the vehicle charging data cloud platform screens charging stop data records caused by charging interface hardware faults in the vehicle number in the information table, meanwhile, the vehicle charging data cloud platform screens charging stop data caused by charging interface hardware faults in charging piles meeting the charging pile number and charging pile GPS location information, which are inquired by the vehicle request in the information table, the target vehicle judges whether overcharge interface faults happen in a plurality of different charging piles in the near future again, if so, the target vehicle sends a fault judgment result as the vehicle fault, otherwise, the target charging pile continuously judges whether different vehicles send charging fault in the near future, if so, sending a judgment result to the target vehicle as the charging pile fault, otherwise, sending a judgment result that the specific fault position cannot be judged to the target vehicle; and if the vehicle charging data cloud platform judges that the target vehicle sends the fault positioning request, the vehicle charging data cloud platform judges whether the vehicle sends normal charging end data again, and the judgment is continued according to the fault determining step.

Judging according to the data screening result of the process, judging whether the overcharge interface faults occur in a plurality of different charging piles (such as two or more than two charging piles) in the recent period (such as about 1 month) of the vehicle number, if so, judging whether the most probable fault position is the vehicle charging socket fault by the vehicle charging data cloud platform, if not, judging according to the data screening result of the step, judging whether a plurality of different electric vehicles have the overcharge interface faults and the electric vehicles do not have similar faults in the charging of other charging piles in the recent period (such as about 1 month) of the charging pile number or the charging pile at the GPS position, if so, judging the most probable fault position is the charging pile charging plug fault by the vehicle charging data cloud platform, and if so, sending the judgment result to the vehicle to be the "charging pile fault", otherwise, the target vehicle charging data cloud platform cannot judge the fault position, and the judgment result is sent to the target vehicle, namely that the fault position cannot be judged.
