[0034] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0035] In one embodiment, as shown in Figure 1 a structural diagram of a maintenance-free non-electric charging device is provided, which includes a first connecting part 100, an interactive identifier 200 and a second connecting part 300. It is worth noting that the maintenance-free non-electric charging device refers to a charging pile that does not need manual maintenance. The design idea is to delete the parts that are easy to wear out and need power supply from the traditional charging pile, thereby achieving the effect of maintenance-free. Specifically, the maintenance-free non-electric charging device does not fixedly connect the power supply device for charging electric vehicles, and does not need to rely on the power grid, so that the infrastructure has almost no requirements and can be distributed according to actual needs.

[0036] The maintenance-free non-electric charging device can be fixedly arranged or movably arranged, which is not limited herein.

[0037] When the user needs to charge the vehicle or the unmanned vehicle needs to charge the vehicle, the user can operate the first connecting component 100 to connect with the vehicle or the unmanned vehicle. At this time, the user needs to access the server through the user terminal to identify the interactive identifier. The server generates scheduling information according to the obtained user information, and calls the power supply device according to the scheduling information. It is worth noting that after the connection between the first connecting component 100 and the vehicle is completed and the user identifier is identified, the user can leave the scene without waiting, which is consistent with the current charging pile charging process. That is, the present application changes the current charging method without affecting the use method on the user side. Specifically, the interactive identifier can be a two-dimensional code, a bar code, a small program code, etc.

[0038] The server is the scheduling center of the power supply device, which charges the vehicle to be charged through the power supply device and the second connecting component 300.

[0039] It is worth noting that the first connecting component can be a charging gun or other types of interfaces, and the information collection capability is realized after the above connection. The second connecting component is the docking component of the power supply device and the maintenance-free non-electric charging device, which can be connected in a contact manner, a wireless manner, etc. The specific form of the above connecting component is not limited. In addition, for the server, a local server of a local area network can be used, or a server connected to the Internet can be used. The power supply device can be understood as a dispatchable energy source, which is simply understood as a device for storing electric energy. The device is different from the mobile energy storage device on the market, and the purpose of its design is to charge the vehicle. Therefore, it needs to meet the requirements of the charging protocol, voltage, current, power, etc. of the vehicle charging, and also needs to maintain a certain information processing capability, which can obtain the first connection information through the docking with the maintenance-free non-electric charging device.

[0040] In a typical case, the power supply device is an intelligent energy storage robot that can receive instructions to drive unmanned, so as to obey the scheduling of the server. Through the scheduling of electric energy, there is actually no restriction on the site where the maintenance-free non-electric charging device is arranged.

[0041] In another typical case, the power supply device is not an intelligent energy storage robot, but only an energy storage device, but is distributed in a set warehouse. The server broadcasts an electricity demand in the form of an order, and the energy storage device warehouse will respond to the order and report the energy storage device that meets the requirements. The energy storage device that meets the requirements is transported to the designated position through other mobile platforms.

[0042] The maintenance-free non-electric charging device is no different from the traditional charging pile mode in user experience on the user side. The user only needs to connect the vehicle to be charged with the first connecting part, complete the corresponding operation, and then leave to wait for the completion of charging. In the server background, the server generates scheduling information according to the identification interaction mark of the user terminal, calls the power supply device, obtains the information of the vehicle during the interaction, calls the matching power supply device, and charges the vehicle to be charged. The effect of charging different brand new energy vehicles by using the charging device can be achieved. This process is transparent to the user. At the same time, since the maintenance-free non-electric charging device does not participate in the power supply part, it is not necessary to upgrade the maintenance-free non-electric charging device when the charging protocol is upgraded, thereby reducing the maintenance cost. In addition, since the maintenance-free non-electric charging device does not have any electrical elements, the interface part has a long design life and almost does not need to be maintained, so that the maintenance-free effect can be achieved as a whole.

[0043] In one of the embodiments, when the power supply device detects the connection information of the second connecting part, the second connection information is generated, the first connection information and the second connection information are verified, and the vehicle to be charged is charged after the verification is passed.

[0044] In another embodiment, when the power supply device detects the connection information of the connection between the power supply device and the second connecting part, the communication between the power supply device and the second connecting part is established; the power request instruction is sent to the power supply device through the communication mode, and the second connection information is generated according to the feedback information of the power supply device responding to the power request instruction.

[0045] In this embodiment, the second connection information is generated after the interaction between the power supply device and the maintenance-free non-electric charging device. On the one hand, the power supply device actively obtains the first connection information through the first connecting part, and on the other hand, the power supply device also identifies the information of the connected second connecting part. After the first connection information and the second connection information are confirmed, the power supply device actively charges the vehicle to be charged.

[0046] It is worth noting that the present application does not limit one power supply device to one maintenance-free non-electric charging device. In a specific scenario, the present application can use one power supply device to supply power to multiple maintenance-free non-electric charging devices, or one maintenance-free non-electric charging device can correspond to multiple power supply devices. In a more ideal case, one power supply device corresponds to one maintenance-free non-electric charging device.

[0047] In one of the embodiments, the interaction information is generated by the user terminal interacting with the server, the user terminal establishes information interaction with the server through the pre-set connection identifier, receives the operation instruction of the user terminal through the information interaction, and generates the interaction information containing at least the user information through the set computer program matching the operation instruction. In this embodiment, the user terminal can be a mobile phone, a PAD, a wearable device, etc. The user terminal interacts with the maintenance-free electric-free charging device, and the user terminal accesses a specific webpage, a mini program, an APP, etc. to establish a connection with the server, so as to realize the connection of the user terminal and the maintenance-free electric-free charging device.

[0048] For the operation of the user side, there is no difference from the traditional charging mode, but there is a big difference in the background processing. For the traditional charging mode, the server only needs to verify the information of the user and the user has enough resources to pay the charging fee, and then starts the charging pile. In the present application, since the electric-free charging mode is adopted, the server needs to collect the information of the user and schedule the power supply module, and the power supply device actively acquires the first connection information and the second connection information after arriving at the scene, so as to realize power supply through information confirmation.

[0049] In one of the embodiments, the power supply device detects the connection of the first connecting part and the vehicle to be charged, collects the vehicle information of the vehicle to be charged, and generates the first connection information.

[0050] In this embodiment, once the vehicle to be charged is connected with the maintenance-free electric-free charging device, since the maintenance-free electric-free charging device does not have information processing function, it actually does not process information. After the charging device arrives at the scene, since the maintenance-free electric-free charging device is powered, the vehicle information of the vehicle to be charged can be collected. The vehicle information contains charging protocol, power-on detection information, battery capacity, current power, vehicle identifier, etc. The above information can be obtained according to actual needs. For example, when it is necessary to confirm the capacity of the called power supply device, the vehicle information to be obtained at least includes the battery capacity and the current power, so as to calculate the required capacity for full charging, which is used as a scheduling condition to call the power supply device.

[0051] It is worth noting that the first connection information can also include the identification information of the vehicle. Since the server pre-stores the binding information of the user and the identification information of the vehicle, it can be determined whether it is a real vehicle to be charged through the interaction identifier.

[0052] In one of the embodiments, the first connection information includes: a vehicle charging protocol and a power-on detection information; the power supply device checks the vehicle charging protocol and the power-on detection information, and charges the vehicle to be charged after the check is passed. In this embodiment, since the charging protocols of new energy vehicles of different brands are different, if mixed charging is adopted, the best charging experience cannot be achieved, and in serious cases, charging may not be implemented, for example, a Tesla charging pile cannot adaptively charge other brand new energy vehicles. It should be noted that the vehicle charging protocol contains a large amount of information, for example, by analyzing the vehicle charging protocol, the maximum charging power that can be supported by the vehicle, and the voltage and current values of the charging platform can be obtained. It can be known that, since the present application adopts the calling mode to schedule the power supply device, the power supply device with appropriate power, which can support voltage and can support current, is selected, which can meet the charging demand of the vehicle, and therefore, the design of the power supply device in the present application does not need to meet the charging demand of a power supply device, but only needs to consider the design of different power supply devices under the charging demand. In fact, user information can be obtained during the interaction between the user terminal and the server, and since the user's vehicle information is filled in when the user information is registered, the power supply device suitable for the vehicle information can be scheduled to the maintenance-free no-electric charging device when scheduling the power supply device, and the power supply device is checked by obtaining the second connection information, and charging is performed after the check is passed.

[0053] In another case, the server can also store the preferred charging power of the vehicle to be charged, which cannot be greater than the maximum supported charging power, or the user can customize the charging power to call the power supply device, and at the same time, the charging power can also be set. It should be noted that in this embodiment, the power supply device can be scheduled according to different needs.

[0054] In one of the embodiments, the first connection information further includes: charging location information, the server obtains the charging location information in the interaction identifier according to the interaction with the user terminal, and calls the power supply device to move to the charging position indicated by the charging location information.

[0055] In this embodiment, the charging location information refers to the geographic location, and since the power supply device can move in various forms, the following examples are given:

[0056] 1. Artificial forwarding mode, in this mode, the geographic location can be sent to the terminal of the artificial person, and the artificial person forwards the power supply device to the charging position indicated by the charging location information through the navigation mode.

[0057] 2. Intelligent frame forwarding mode, in this mode, the geographic location can be sent to the intelligent frame, and the intelligent frame forwards the power supply device to the charging position indicated by the charging location information through the navigation mode.

[0058] 3. The intelligent power supply device, in this mode, the power supply device itself has the autonomous navigation function, after receiving the charging position information, moves to the charging position indicated by the charging position information.

[0059] The above-mentioned mode can be realized in the way of combination according to actual conditions.

[0060] In one embodiment, when the remaining power of the power supply device is less than the threshold value, the first connection information is sent to the server again; or the server is requested to call other power supply devices.

[0061] In this embodiment, due to various reasons, the remaining power in the power supply device may not meet the charging demand, at this time, the first connection information can be sent to the server again to call the power supply device again, or the server is requested to call the power supply device again according to the information requested last time.

[0062] For the overall maintenance-free charging system, the power supply device is not only one or several, but also a large number of power supply devices with different discharge power, different capacity, and different charging protocol. When the power supply device is called, the actual scheduling is carried out according to the principle of meeting the user demand, for example, the user needs to charge 30 degrees of electricity, then a power supply device containing at least 30 kilowatt hours is scheduled. Even if there is no power supply device containing at least 30 kilowatt hours, two power supply devices containing at least 15 kilowatt hours can be scheduled to charge at the same time. Then in another case, the user may modify the order in the middle, from charging 30 degrees to 60 degrees, then the re-scheduling according to the mode of this embodiment can meet the demand.

[0063] In one of the embodiments, the processing module sends the charging process information to the server to make the server generate the charging information and push it to the user terminal.

[0064] In this embodiment, the user can pay attention to the charging dynamic in time by accessing the webpage, applet, APP and the like.

[0065] In one embodiment, as shown in Figure 2 A charging method is provided, including

[0066] Step 202, receiving the scheduling information generated by the user terminal identifying the interactive identifier through the server, and calling the power supply device according to the scheduling information.

[0067] Step 204, when the power supply device detects the connection with the second connection component, the first connection component is activated to obtain the first connection information; the first connection component is used to connect the vehicle to be charged.
