The invention relates to an electric vehicle intelligent charging method supporting phase rotation and equipment thereof, and the method comprises the following steps: obtaining the respective power supply loads of three phases, and calculating and defining the highest power supply load phase and the lowest power supply load phase; when an electric vehicle is connected to a charging pile for charging, switching, by the charging pile, to the lowest power supply load phase, and supplying power to the electric vehicle; under other conditions, obtaining the charging power of each charging pile inreal time, if the standard deviation of the total charging power of each phase of the three phases is larger than a first threshold value, obtaining an equilibrium distribution scheme of the three phases through calculation, and switching the power supply phase corresponding to each charging pile according to the equilibrium distribution scheme. According to the invention, the power supply phase corresponding to each charging pile is switched according to the equilibrium distribution scheme, the impact and damage to a power grid caused by the imbalance of high-power three-phase loads are reduced, and the electric quantity used by the three phases is balanced.
