AUTEL DIGITAL POWER CO., LTD.

A charging pile includes a first housing and a second housing, the first housing defines a first air channel in an annular shape, the first housing includes a heat dissipation housing and a heat exchange housing arranged along the circumference of the first air channel, and a power module of the charging pile is provided in the heat dissipation housing. The second housing defines a second air channel, and the second housing is configured to allow external air to enter and be exported from the second air channel. The second housing is in contact with the heat exchange housing.

A power distribution method includes: acquiring a charging demand of a target charging terminal, wherein the target charging terminal is connected with a first direct-current bus which is any direct-current bus in a charging device; and in a case where power provided by a power assembly that has been switched into the first direct-current bus does not satisfy the charging demand, if a directly connected power assembly of the first direct-current bus has been switched in, switching a first power assembly into the first direct-current bus, wherein the directly connected power assembly is directly connected with the first direct-current bus, the first power assembly is one power assembly which has not yet been switched in, and the first power assembly is connected to the directly connected power assembly and has a smallest distance to the directly connected power assembly.

Embodiments of the present disclosure relate to the field of charging piles, and disclose a charging gun returning control method and device for a charging pile, a charging pile, and a medium, wherein the method includes: acquiring a signal intensity change generated between a charging gun and a gun seat when the charging pile is in a non-charging state; determining that a current operation is a gun unplugging operation when it is detected that the signal intensity change is less than a gun unplugging change threshold; and determining that the current operation is a gun plugging operation when it is detected that the signal intensity change is greater than a gun plugging change threshold; where the gun unplugging change threshold and the gun plugging change threshold are mutually opposite numbers.

A charging apparatus, includes a charging pile and a charging gun. The charging pile is provided with a slot, and a reader is provided in the slot; a charging gun is connected to the charging pile, the charging gun includes a gun head, the gun head is used for plugging into a slot, and the charging gun is provided with at least two electronic tags; in a state where the gun head is just plugged into the slot, the reader just identifies an electronic tag, and in a state where the gun head is completely plugged into the slot, the reader just identifies another electronic tag; therefore, the charging apparatus can distinguish whether the charging gun corresponds to returning a gun and whether the charging gun is returned in place.

A charging device comprises a charging pile and a charging pile gun head connected via a transmission cable, wherein the charging pile gun head is provided with a pressing detection module, and the charging pile is provided with a control module connected to the charging pile gun head, and a wireless communication module and an output adjustment module connected to the control module. In operation, the charging device receives a pressing operation of a user, correspondingly outputs a charging instruction to the electric automobile to control the opening and closing of a charging base cover door, and adjusts the charging state when the charging pile gun head is connected to the charging base of the electric automobile. The process does not require the user to manually open or close the charging base cover door, and the user can adjust the output of the charging pile via the charging pile gun head.
