When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 In one embodiment, a fast charging pile combination system includes several charging piles, each charging pile is provided with a main control unit, several charging guns, several receiving sockets and several rectifier units, the several charging guns, several receiving sockets and several rectifier units are connected to the main control unit, the several charging piles are connected through the several charging guns and several receiving sockets, the several charging guns, several receiving sockets are connected to the main control unit for signal connection, and the several rectifier units are externally connected to an AC power supply.

[0023] Specifically, based on the above embodiment, each charging gun includes a first communication module and a charging interface, the DC output end of each rectifier unit is connected to the charging output line of the charging interface, the charging output line is connected to the power receiving socket, and the first communication module is connected to the main control unit signal.

[0024] Specifically, based on the above embodiment, each power receiving socket includes a power receiving interface and a second communication module. The DC input line of the power receiving interface is connected to the charging output line through an internal control switch, and the second communication module is connected to the main control unit signal.

[0025] Specifically, based on the above embodiment, each charging gun is provided with a first communication interface, and each receiving socket is provided with a second communication interface. The first communication interface can be inserted into the second communication interface to achieve communication connection.

[0026] It can be understood that when the charging gun of the first charging pile is inserted into the receiving socket of the second charging pile, the communication interface and charging interface of the first charging pile are connected to the communication interface and receiving interface of the second charging pile respectively; this connection method provides a physical basis for establishing communication; the two charging piles use a specific communication protocol, such as a CAN (Controller Area Network) bus protocol or a custom serial communication protocol. Under the CAN bus protocol, the charging pile can distinguish different types of messages, such as charging power demand messages, charging pile status messages, etc., by defining different identifiers (IDs). When the charging gun is inserted into the receiving socket, the two parties establish communication through these interfaces by sending and receiving messages containing specific identifiers; after obtaining relevant charging information through communication, the internal control switch is controlled according to the charging demand, thereby realizing the superposition of power from multiple charging piles.

[0027] Furthermore, a control circuit unit is provided inside the charging pile to control the connection and disconnection of the internal control switch, and the control circuit is connected to the main control unit; specifically, taking two adjacent charging piles A and charging pile B as an example, when the charging gun of charging pile A is inserted into the receiving socket of charging pile B, the communication interface and charging interface of charging pile A are respectively connected to the communication interface and receiving interface of charging pile B, and charging pile A and charging pile B establish communication connection through the communication interface. The charging output line of the charging interface of charging pile A is connected to the DC input line of the receiving interface of charging pile B through the internal control switch of charging pile B. When the internal control switch of charging pile B is disconnected, charging pile B uses the electric energy output by the B gun rectifier unit to charge externally, and the internal control switch of charging pile B is disconnected. When the control switch is turned on, the electric energy output by charging pile A is transmitted to the DC input line of charging pile B through the charging output line of the charging interface of charging pile A and is transmitted to the charging output line of charging pile B through the internal control switch of charging pile B. The electric energy output by charging pile A is superimposed with the electric energy output by the B-gun rectifier unit of charging pile B and charged externally at the same time. At this time, the total charging power is the sum of the charging power of charging pile A and the charging power of charging pile B. After the charging gun of charging pile B is inserted into the receiving socket of the externally charged electric vehicle, the internal control switch is controlled to be turned on after the charging gun of charging pile B establishes communication with the externally charged electric vehicle, so that the charging energy output by charging pile A is superimposed on the charging energy of charging pile B to charge the electric vehicle.

[0028] In summary, this application adds a receiving socket to the charging pile to connect to the charging guns of other charging piles, superimposes the charging power output by other charging piles with the power of this charging pile, and charges the outside through one or more charging guns of this charging pile, which can quickly and easily increase the charging power or charging speed of the charging pile; the entire product structure is simple, easy to produce, low cost, and easy to promote.

[0029] Specifically, on the basis of the above embodiment, a storage seat is further included. Each charging pile is provided with a plurality of storage seats, and the storage seats are used to place a plurality of charging guns.

[0030] It is understood that when the charging gun is not in use, it is placed in the storage base. The storage base can be customized according to the shape and size of the charging gun to ensure that the charging gun can be securely placed therein.

[0031] For details, please refer to Figure 4 On the basis of the above embodiment, it further includes a temperature sensor. Each charging gun is provided with a temperature sensor, and the temperature sensor is connected to the main control unit signal.

[0032] It is understood that when the charging gun starts working, the temperature sensor collects the temperature data of the charging gun in real time and transmits this data to the main control unit; the main control unit will analyze this data. By setting the temperature sensor on the charging gun, it is mainly used to monitor the temperature of the charging gun during the charging process. Since the current passes through the charging gun during the charging process, if the charging power is high or there is a fault in the charging gun itself (such as poor contact, etc.), it may cause the charging gun to heat up. Monitoring the temperature of the charging gun can promptly detect abnormal heating to ensure charging safety.

[0033] For details, please refer to Figure 3 , Figure 4 On the basis of the above embodiment, it also includes an electronic lock, which is provided on the storage seat and is connected to the main control unit signal.

[0034] As you can understand, the electronic lock uses electromagnetic force to control the opening and closing of the lock. When the main control unit sends an unlock signal, the electromagnet of the electromagnetic lock is de-energized, and the lock tongue retracts, thereby unlocking the lock. The electronic lock is placed on the storage base, mainly to ensure the safe storage of the charging gun. It prevents the charging gun from being removed or tampered with by unauthorized personnel. The electronic lock will only unlock and allow the charging gun to be removed when certain conditions are met (such as charging completion, payment, etc.).

[0035] Specifically, based on the above embodiment, a display screen (not shown in the figure) is further included. Each charging pile is provided with a display screen, and the display screen is connected to the main control unit.

[0036] As you can understand, the display screen is connected to the main control unit and is primarily used to display charging-related information to the user. The main control unit transmits charging-related data to the display screen, which then displays information based on the received data. Specifically, it can display information such as the current charging status (charging, charging completed, etc.), charging power, charged capacity, estimated time to full charge, and charging cost. This allows users to intuitively understand the charging status.

[0037] In summary, a fast charging pile combination system is composed of at least two of the above-mentioned charging piles. For example, in one embodiment, it includes charging pile A and charging pile B. Please refer to Figure 1 , Figure 1 This is a scenario where two charging piles are interconnected and charging. The charging power of charging pile B and charging pile A are both 120KW. The charging gun of charging pile A is inserted into the receiving socket of charging pile B. The charging power of charging pile B and charging pile A is superimposed to charge the electric vehicle. The maximum charging power is twice that of a single charging pile, 240KW when charging with a single gun, and 120KW for each gun when two guns are used.

[0038] When the charging gun of the charging pile A is inserted into the receiving socket of the charging pile B, the first communication interface and the charging interface of the charging gun on the charging pile A are respectively connected to the second communication interface and the receiving interface of the receiving socket on the charging pile B, and the charging pile A and the charging pile B establish communication connection through the first communication interface and the second communication interface. The charging output line of the charging interface of the charging pile A is connected to the DC input line of the receiving interface of the charging pile B through the internal control switch of the charging pile B. The electric energy output by the charging pile A is transmitted to the DC input line of the charging pile B through the charging output line of the charging interface of the charging pile A and is transmitted to the charging output line of the charging pile B through the internal control switch of the charging pile B. It is superimposed with the electric energy output by the rectifier unit of the charging pile B and charged externally at the same time. At this time, the total charging power is the sum of the charging power of the charging pile A and the charging power of the charging pile B. After the charging gun of the charging pile B is inserted into the receiving socket of the externally charged electric vehicle, the internal control switch is controlled to be turned on after the charging gun of the charging pile B establishes communication connection with the externally charged electric vehicle, so that the charging electric energy output by the charging pile A is superimposed on the charging pile B to charge the electric vehicle.

[0039] In another embodiment, please refer to Figure 2 As shown, Figure 2 This is a scenario where three charging piles are interconnected and charging. For example, in addition to charging piles A and B, there is also charging pile C. Charging piles A, B, and C all have the same charging power of 120kW. The charging gun of charging pile A is inserted into the receiving socket of charging pile B, and the charging gun of charging pile C is inserted into the receiving socket of charging pile B. The charging power of charging piles A, B, and C is added together to charge the electric vehicle. The maximum charging power is three times that of a single charging pile, with a maximum power of 250kW when charging with a single gun, and 180kW when using two guns.

[0040] For example, charging pile B is used as the output, charging piles A and C are inserted into charging pile B, and charging pile B charges the vehicle.

[0041] Furthermore, in the above embodiment, charging pile A and charging pile B have the same power or different powers. When there are more than three charging piles, each charging pile has the same power or different powers; preferably, they have the same power to facilitate mutual matching.

[0042] The present application provides a fast charging pile combination system, which adds a receiving socket to the charging pile to connect to the charging guns of other charging piles, superimposes the charging power output by other charging piles with the power of this charging pile, and charges the outside through one or more charging guns of this charging pile, which can quickly and easily increase the charging power or charging speed of the charging pile; the overall product structure is simple, easy to produce, low cost, and easy to promote.
