[0002] With the rapid development of the new energy vehicle industry, the requirements for the intelligence and flexibility of new energy vehicle charging piles are becoming increasingly stringent. In real-world scenarios, users may be limited by poor mobile phone signal conditions (such as in underground parking garages) and can only use non-intelligent charging protection systems. However, when the mobile phone signal in the parking garage improves, if users want to use an intelligent charging protection system, the traditional non-intelligent charging protection system can only be replaced by dismantling and cannot be upgraded to an intelligent charging protection system. Summary of the Invention

[0007] The external power supply provides power to the battery sequentially through the charging cable and the charging gun head. The mechanical lock detection circuit is connected to the charging gun head, and the first short-range communication module and the second short-range communication module are wirelessly connected.

[0008] Preferably, the first short-range communication module and the second short-range communication module are Bluetooth modules, Wi-Fi modules, ZigBee modules, or combinations thereof.

At the same time, it receives control commands from the remote management platform and then wirelessly controls the charging protection system through the second and first short-range communication modules in sequence. It also uploads the status information of the charging gun socket to the remote management platform. The remote management platform is a server with wireless communication capabilities.

Attached Figure Description

[0025] The accompanying drawings, which are included to provide a further understanding of the invention and form part of this invention, illustrate exemplary embodiments of the invention and are used to explain the invention, but do not constitute an undue limitation of the invention. In the drawings:

[0026] Figure 1 This is a schematic diagram of the principle of a charging pile that connects to the network via a charging gun socket, according to the present invention. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0028] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, this invention proposes a charging pile that connects to the network via a charging gun socket, including a charging protection system, a charging cable and charging gun head, and a charging gun socket. The charging protection system is connected to the charging gun socket sequentially via the charging cable and charging gun head. The charging cable and charging gun head conform to the definition in GB / T 18487.1, and have a built-in control guidance circuit (hereinafter referred to as CP circuit) conforming to connection method B or connection method C. The charging gun head also has a mechanical locking device. Furthermore, the charging cable and charging gun head can have a built-in mechanical lock button status detection circuit, which can realize the status detection of the charging gun head and be collected by the charging protection system.

[0030] The charging protection system includes a first main controller and a mechanical lock detection circuit and a first short-range communication module electrically connected to the first main controller. The first main controller, mechanical lock detection circuit, and first short-range communication module are powered by external power. The charging protection system conforms to the Mode 2 or Mode 3 charging protection system defined in GB / T 18487.1, and can independently perform AC charging of new energy vehicles. It has a built-in short-range communication module for short-range communication. The charging protection system uses external power, which can also be output through the charging cable and charging gun to charge the load.

[0031] The charging gun holder includes a second main controller and a second short-range communication module and a wireless communication module electrically connected to the second main controller. All three modules are connected to a battery. The charging gun holder has a built-in short-range communication module that can pair with the short-range communication module built into the charging protection system for information exchange. It also has a built-in wireless communication module that can perform remote network communication via wireless communication signals. Additionally, a mechanical lock detection circuit is connected to the charging gun head to identify whether the charging gun head is connected to the charging gun holder. The charging gun holder uses a built-in battery to power the internal control circuitry and communication module.

[0032] External power supplies the battery sequentially through the charging cable and charging gun. When the charging cable and charging gun are connected to the charging gun socket, the power output from the charging gun can be used to replenish the battery pack. The charging gun socket determines the battery pack's power status and sends a control signal via a short-range communication module to initiate the charging process. This power supply can be either AC or DC. In AC charging mode, power is transferred to the charging socket via the L / N terminals, requiring the charging gun socket to have a built-in AC-DC power module and a relay in the charging protection system to close the high-voltage circuit. In DC charging mode, power is transferred to the charging socket via the CP / PE terminals, requiring an independent switch within the charging protection system to short-circuit the CP line to the DC power output terminal.

[0033] like Figure 1 As shown, the first and second short-range communication modules are wirelessly connected and can be paired with one or more other short-range communication modules of the same type through a pairing process. They can receive control from the pairing device or upload information to the pairing device. These modules can be Bluetooth, Wi-Fi, ZigBee, or combinations thereof. The first and second short-range communication modules can wirelessly communicate with smart mobile terminals, vehicles, and charging gun sockets equipped with similar communication modules. Smart mobile terminals include smartphones, PDAs, tablets, laptops, and in-vehicle computers.

[0034] The information exchanged between the first and second short-range communication modules includes: authorization information of the charging protection system, control information of the charging protection system, status information of the charging protection system, charging power information of the charging protection system, and fault diagnosis information of the charging protection system; the charging protection system performs wireless upgrades by sequentially downloading upgrade data packets through the first short-range communication module, the second short-range communication module, and the wireless communication module.

[0035] Simultaneously, the wireless communication module wirelessly connects with the remote management platform (through a specific protocol, such as OCPP, or a proprietary protocol), sequentially uploading information obtained through the first and second short-range communication modules to the remote management platform. It also receives control commands from the remote management platform and then wirelessly controls the charging protection system sequentially through the second and first short-range communication modules. Furthermore, it uploads the status information of the charging gun holder to the remote management platform, such as whether the charging gun is in place and whether the battery pack has sufficient power. The remote management platform is a server with wireless communication capabilities.

[0036] This invention also proposes a networking method for charging piles that connect to the network via a charging gun socket, comprising the following steps:

[0037] a) Adjust the charging protection system to allow pairing;

[0038] b) The smart mobile terminal is paired with the charging protection system. During pairing, a unique string is entered for authorization identification. This string is generated by the manufacturer before leaving the factory and sent to the user in a confidential manner.

[0039] c) The smart mobile terminal controls the charging protection to re-enter the pairing state and selects whether to pair with the vehicle or the charging gun socket; if pairing with the vehicle is selected, control is performed on the vehicle interface; if pairing with the charging gun socket is selected, there are two ways to control pairing: 1) Launch the application on the smart mobile terminal to remotely control the charging gun socket, upload the information of the charging protection system to be paired, and control the charging gun socket to pair with it; 2) Insert the charging gun into the charging gun socket.

[0040] d) After pairing, the smart charging function is activated via a smart mobile terminal or the application installed in the vehicle, while simultaneously monitoring the status of the charging protection system. At the same time, control commands are sent to the charging gun socket via a remote management platform, which then controls the charging protection system to activate the smart charging function. The smart charging function includes plug-and-charge functionality, scheduled charging functionality, private charging station sharing functionality, and orderly charging functionality, and can also be implemented via a smart mobile terminal, the application installed in the vehicle, or the remote management platform.

[0041] When the charging protection system is paired with the vehicle, it sends a signal to the vehicle to open the charging door by pressing the mechanical lock of the charging gun (e.g., pressing it three times in a row within 5 seconds), allowing the vehicle to automatically open the charging door.

[0042] The above steps involve adjusting the charging protection system to a pairing-enabled state, including:

[0043] When there is no paired device in the charging protection system, it is achieved by coordinating the timing of the external power switch with the button of the mechanical lock on the charging gun head;

[0044] When the charging protection system already has paired devices, it sends a specific command through the paired device to enter the pairing allowed state: if the paired object is a smart mobile terminal, it is controlled through the application on the smart mobile terminal; if the paired object is a charging gun socket, it sends the command through the remote management platform; when all paired devices of the charging protection system fail, a dedicated wireless control device is used for control. The dedicated wireless control device has a built-in dedicated protocol that matches the charging protection system, and it performs pairing when the charging protection system has not entered the pairing allowed state.

[0045] In addition, the paired charging protection system can be de-paired as needed, and the steps include any of the following: de-pairing via a smart mobile terminal or an application installed on the vehicle; de-pairing by sending a control command through a remote control platform; or de-pairing using a dedicated wireless control device.

[0046] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
