Beschreibung
Zusammenfassung:	The invention relates to a charging pile charging and discharging control method and a system. The method comprises the steps that the charging requirement of an electric vehicle and the operation state of a power grid are detected; when the power grid is in a peak electricity period, if the electric vehicle has no charging requirement, the energy storage power supply outputs electric energy to the power grid; if the electric vehicle has the charging requirement, the energy storage power supply outputs the electric energy to the electric vehicle to charge the electric vehicle; when the power grid is in a valley electricity period, if the electric vehicle has no charging requirement, the power grid outputs electric energy to the energy storage power supply to charge the energy storage powersupply; and if the electric vehicle has the charging requirement, the power grid outputs the electric energy to the electric vehicle to charge the electric vehicle. The electric energy output flow directions of the power gri
