[0002] A charging pile is an energy supplement device that provides power for electric vehicles. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. At present, the electric vehicle charging piles on the market are mainly divided into two types: single gun charging piles and double gun charging piles.

[0003] Under the condition of connecting to the same input current, the output power of a single gun charging pile is higher than that of a single charging gun in a double gun charging pile. Therefore, the charging speed of a single gun charging pile is faster, while the advantage of a double gun charging gun is that it can charge two vehicles simultaneously.

[0004] In public charging places such as shopping malls or large parking lots, if single gun charging piles are equipped, the demand for multiple vehicles to charge simultaneously cannot be met during peak charging periods in the afternoon or evening; if double gun charging piles are equipped, the demand for a single vehicle to charge quickly cannot be met during off-peak charging periods in the morning or late at night; this results in the inability of public charging places to meet the different charging needs of users at different times.

[0031] A housing 1 and a charging component. The housing 1 forms an installation cavity 1a and two charging windows 1b communicating with the installation cavity 1a; the charging component includes a storage battery 21, a single-chip microcomputer control device 22, and two charging interfaces 23.
