The invention discloses an ordered charging method for an electric automobile. The ordered charging method comprises the steps of: obtaining a daily load prediction curve of a zone area on the same day based on a platform area load prediction model; obtaining a total load prediction curve of the zone area on the same day based on the daily load prediction curve of the zone area on the same day andthe electric automobile charging load prediction curve required by the zone area on the same day; determining whether a power peak period exists or not based on the total load prediction curve of thezone area on the same day; acquiring the demand of a predicted total charging amount of the receiving scheduling of the zone area on the same day, and calculating an ideal charging time period and aplatform area smooth load; and arranging a user charging time frame to an ideal charging period. According to the method, the total charging power of the electric vehicles in the zone area is taken asa decision variable, so that the electric vehicles are sequentially charged and controlled, electric vehicle users can be guided to charge in a valley price period of a non-power grid load peak, andthe charging cost of the users is reduced.
