The invention provides a method for upgrading an alternating current charging pile from disordered charging to ordered charging, and relates to the field of intelligent ordered charging of electric automobiles. The method comprises the steps that a current transformer is additionally arranged on a live wire of each unordered charging pile, and the current transformers are used for collecting currents of the unordered charging piles; the disordered charging pile is an electric vehicle alternating current charging pile; according to the current, determining charging power and idle power when the disordered charging pile charges the electric vehicle; by monitoring the real-time loads of the distribution transformer, the disordered charging pile and the direct current charger, according to the surplus capacity of the distribution transformer, the charging requirement of the electric vehicle, the charging power and the idle power, the charging load of the electric vehicle and the residential electricity load are coordinated, and an ordered charging strategy is formulated; and matching different charging powers for different disordered charging piles according to the ordered charging strategy. Electric energy supply of the electric automobile and operation safety of a power grid are guaranteed.
