Charging pile supporting economic regulation and control

The invention provides a charging pile supporting economic regulation and control, and the charging pile comprises a regulation and control module which is used for carrying out the economic regulation and control of the charging power of an electric vehicle based on a strategy according to the current electricity price peak or valley time period and the current electric quantity of the electric vehicle when the charging pile charges the electric vehicle; the strategy comprises the following steps: if the current time is in an electricity price valley time period, charging by using rated power; if yes, whether the electric quantity needing to be charged by the electric vehicle battery is larger than a set value or not is judged, if yes, charging power is reduced, and if not, rated power is used for charging; and judging the current time regularly, and adjusting the charging strategy according to the rule when the peak and valley time periods of the electricity price jump. The method has the advantages that th
