Abstract: A method and device for controlling a charging station, and a charging station system. The charging station includes multiple charging positions each comprising a charging pile and a parking space corresponding to the charging pile. The method includes: obtaining in real time first information comprising usage status information and daily usage information of the charging piles and occupancy status information of the parking spaces, the usage status information is information about whether the charging piles being currently in use, and the daily usage information is information about a quantity of charging piles used in a predetermined time period of each day; and determining parking information according to the first information, the parking information comprises a quantity of first available parking spaces used for fuel vehicles and a quantity of second available parking spaces used for electric vehicles.

Abstract: A charging pile, and a device, system and method for testing a charging pile are provided. An inner side of a port of one of the gun bases is connected to an inner side of the same port of the other of the gun bases. An outer side of each port of each gun base connected to a port of a charging gun connected to the gun base, so that the two charging guns are connected. In addition, one of the two charging guns operates in the forward output state and serves as tested gun to be tested. The other of the two charging guns operates in the reverse conversion state and serves as a testing gun to test the tested gun. The gun base controller saves and exports the communication data on the communication bus between the two charging guns.

Abstract: An integrated charging device, a charging pile and a method for controlling the charging pile are provided. In the integrated charging device, a controller is communicatively connected to a first end of a communication module. A second end of the communication module includes an external communication port. The external communication port is configured to be communicatively connected to a BMS of a load via a communication line in a charging gun connected to the integrated charging device. That is, the integrated charging device is capable of communicating with the BMS, so that the controller directly communicates with the BMS, without complicated transfer by an MCU and a power control unit in the conventional technology, thereby simplifying communication in the charging pile including the integrated charging device and reducing cost.
