for each charging pile of the plurality of charging piles, screening a plurality of candidate charging control modes matched with the charging parameters from a plurality of pre-stored charging control modes according to the charging parameters corresponding to the electric vehicles electrically connected with the charging piles, wherein the current electric quantity and the target electric quantity corresponding to each candidate charging control mode are matched with the charging parameters corresponding to the electric vehicles, the charging control modes at least comprise charging control parameters corresponding to constant-current charging and constant-power charging, and the charging control parameters at least comprise a charging current value, a charging power value and a charging duration;
for each charging pile of the plurality of charging piles, respectively performing an automobile reference feature acquisition operation on each candidate charging control mode of a plurality of candidate charging control modes corresponding to the charging pile so as to output automobile reference feature information corresponding to each candidate charging control mode;
for each charging pile of the plurality of charging piles, calculating the feature similarity between the automobile feature information corresponding to the electric automobile electrically connected with the charging pile and the automobile reference feature information corresponding to each candidate charging control mode of the plurality of candidate charging control modes corresponding to the charging pile;
And for each charging pile in the plurality of charging piles, screening a matched target charging control mode from a plurality of candidate charging control modes corresponding to the charging pile according to the characteristic similarity between the automobile characteristic information corresponding to the electric automobile electrically connected with the charging pile and the automobile reference characteristic information corresponding to each candidate charging control mode corresponding to the charging pile, and controlling the charging pile to charge the electric automobile according to the target charging control mode.
In summary, according to the control method and system for the charging piles provided by the invention, for each charging pile, under the condition that the charging pile is electrically connected with an electric vehicle, the charging pile is used for determining the charging parameters of the electric vehicle so as to output the charging parameters corresponding to the electric vehicle. And for each charging pile, carrying out automobile characteristic acquisition operation on the electric automobile electrically connected with the charging pile through the charging pile so as to output automobile characteristic information corresponding to the electric automobile. And for each charging pile, screening a matched target charging control mode from a plurality of pre-stored charging control modes according to charging parameters corresponding to the electric automobile electrically connected with the charging pile and automobile characteristic information corresponding to the electric automobile, and controlling the charging pile to perform charging operation on the electric automobile according to the target charging control mode. Based on the method, the charging process is not required to be monitored in real time and the charging mode is not required to be adjusted in real time, so that the resources consumed by charging control can be reduced to a certain extent, and the problem of high resource consumption in the prior art is solved.
