The invention relates to an electric vehicle orderly charging control method. The method comprises the following steps of accounting and calculating the charging load predicting results at the next time frame as per the history data or the charging demand of the conventional electric vehicle by station level management equipment and uploading the charging load predicting results to an electric fence administration center, calculating the available capacity of an electric fence as per the predicting results at the present time frame and the real-time operation state and sending electric fence available capacity command to the station level management equipment by the electric fence administration center, comparing the charging power demand of the present time frame by the station level management equipment and coordinating the charging demand of the electric vehicle if the charging demand of the electric vehicle is smaller than the charging power demand of the present time frame. The invention further relates to an electric vehicle orderly charging control system. The allowance power of a recharge replacement station is restricted reasonably by the electric fence administration center as per the charging load predicting results submitted by the station level management equipment and the operating condition of the electric fence, thereby avoiding the impact to the electric fence caused by power requirements of the recharge replacement station and coordinating the energy source requirements of the electric fence load and the electric vehicle better.
