Description

Technical Field

[0001] The present application relates to the technical field of charging pile equipment, and in particular to a distributed charging pile system and control method for new energy vehicles. Background Art

[0002] As countries around the world increase their attention to environmental protection and the continuous adjustment of the structure of electric energy resources, automobile companies in various countries have gradually started the technical research and development and industrial layout of new energy vehicles. As a green and efficient means of transportation, new energy vehicles are gradually becoming the development trend of future transportation. However, the existing charging piles for new energy vehicles still face many challenges and practical problems in actual applications.

[0003] In some public parking lots or residential parking lots, charging piles are required to be installed at some parking spaces in order to facilitate the provision of charging services for new energy vehicles. Under ideal conditions, new energy vehicles that are being charged are parked in parking spaces equipped with charging piles, which is the best embodiment of the full utilization of charging piles and power resources. In addition, it can also reduce the dependence of some hybrid vehicles on fuel power, which is more conducive to environmental protection and the full utilization of power resources.

[0004] Traditional charging piles in parking lots are usually equipped with a charging pile for each new energy parking space, that is, the ratio of new energy parking spaces to charging piles is usually 1:1. The charging mode of new energy vehicles is a charging setting that strongly binds "new energy vehicles, charging piles, and new energy parking spaces". The above-mentioned "strong binding" will be referred to as the strong binding phenomenon of "car, pile, and space" for new energy vehicles. The charging pile can only charge new energy vehicles in the parking space or adjacent parking spaces.

[0005] In actual application scenarios, due to the lack of effective parking management in parking lots, some owners of pure fuel vehicles (hereinafter referred to as fuel vehicles) sometimes park their vehicles at will in parking spaces equipped with charging piles, resulting in new energy vehicles that really need charging being difficult to charge in time. This not only wastes precious charging resources, but also increases the charging time cost and anxiety of new energy vehicle users, thereby hindering the further popularization and development of new energy vehicles. Summary of the invention

[0006] In order to alleviate the impact of the strong binding phenomenon of "car, charging pile, and parking space" on the charging of new energy vehicles, the present application provides a distributed charging pile system and control method for new energy vehicles.

[0007] On the one hand, the present application provides a distributed charging pile system for new energy vehicles, which adopts the following technical solutions: A distributed charging pile system for new energy vehicles includes a charging dock, a plurality of portable charging piles, and a charging interface device provided at each new energy parking space. The portable charging pile can be taken out of the charging dock and placed in the charging interface device. After the portable charging pile is placed in the charging interface device, the charging interface device can obtain electrical energy from a power grid. A charging control module is provided in each of the portable charging piles. The charging dock is used to supply power to the charging control module. A charging connection mechanism for connecting to new energy vehicles is installed on the charging interface device.

[0008] Through the above technical solution, after the user parks the new energy vehicle in a new energy parking space equipped with a charging interface device, the user controls the charging dock through a mobile terminal (such as a mobile phone, tablet and other smart devices) according to his or her own power needs, and takes out the required portable charging pile from the charging dock. The charging control module in the portable charging pile can feedback the charging information of the new energy vehicle and the operating status of the equipment to the charging dock through wireless signal transmission.

[0009] The charging interface device can only be a power-drawing device for drawing electricity from the power grid. Here, the charging interface device can be simply understood as a "socket" that lacks a conductive medium (i.e., a portable charging pile with a built-in charging control module). After the new energy vehicle owner places the portable charging pile into the charging interface device, the charging circuit in the charging interface device can be connected, so that the user can insert the charging connection mechanism into the new energy vehicle, thereby charging the new energy vehicle.

[0010] This technical solution is equivalent to separating and re-layouting the core components of traditional charging piles, but it is not a simple separation of components. On the one hand, when a gasoline vehicle occupies a new energy parking space, the charging interface device corresponding to the parking space occupied by the gasoline vehicle is only one part of the charging equipment, and the charging control module as the main component is not occupied. At this time, after a new energy vehicle owner drives the vehicle into the parking space, he obtains the charging control module from the charging dock and places it in the charging interface device to perform charging, which effectively alleviates the impact of the strong binding phenomenon of "vehicle, pile, and space" on the charging of new energy vehicles, and also reduces the problem of new energy vehicles being unable to charge due to gasoline vehicles occupying the space.

[0011] On the other hand, since there is no need to equip each charging interface device with a charging control module, the charging control module can be managed uniformly through the charging dock, which effectively reduces the construction cost and operation and maintenance cost of the charging equipment. In practice, the cost of a new energy charging station built using this technical solution is about one-third of the cost of building a traditional charging pile.

[0012] In a preferred example, the present application can be further configured as follows: the charging connection mechanism includes a charging gun, the input end of the charging gun is installed on the charging interface device, and the output end of the charging gun can interact with new energy vehicles for electrical energy.

[0013] Through the above technical solution, after the user places the charging control module into the charging interface device and inserts the charging gun into the new energy vehicle, the user's new energy vehicle obtains electrical energy from the power grid through the charging gun, the charger's accessory cable and the charging interface device, thereby charging the new energy vehicle.

[0014] In a preferred example, the present application can be further configured as follows: the charging control module includes a fast charging module and a normal charging module.

[0015] Through the above technical solution, users can obtain fast charging modules or normal charging modules from the charging dock according to the power status of new energy vehicles and their own travel needs, so as to meet the different charging needs of users and refine the charging logic of this device.

[0016] In a preferred example, the present application can be further configured as follows: a power replenishment module is provided in the portable charging pile, and the charging interface device can provide electrical energy to the charging control module through the power replenishment module.

[0017] Through the above technical solution, the power replenishment module can be a charging circuit or other independent power supply unit for the charging control module to obtain electric energy from the power grid, so as to replenish electric energy for the charging control module in time, reducing the possibility of charging interruption before the user's vehicle is fully charged.

[0018] On the other hand, based on the above-mentioned distributed charging pile system for a new energy vehicle, the present application also proposes a control method for the distributed charging pile system for a new energy vehicle.

[0019] A control method for a distributed charging pile system of a new energy vehicle, the method comprising: According to the charging type of the charging control module, the plurality of charging control modules are divided into a fast charging group and a normal charging group; Obtaining charging control module demand information sent by the user's mobile terminal; According to the demand information of the charging control module, the power information of the charging control module of the fast charging group or the normal charging group is obtained; Based on the power information of the charging control modules of the fast charging group or the normal charging group, if there is a charging control module that has reached a saturated power state in the corresponding group, an unlocking instruction is issued to the charging control module that has reached a saturated power state.

[0020] Through the above technical solution, new energy vehicle owners can scan the QR code on the charging dock through the mobile terminal, establish information interaction between the mobile terminal and the charging dock, and send demand information of the charging control module to the charging dock through the mobile terminal according to actual charging needs, and the charging dock will obtain the information.

[0021] After the charging dock obtains the demand information of the charging control module, it analyzes whether the user needs a fast charging module or a normal charging module, and then sends an unlocking command to the corresponding fast charging module or the normal charging module that has reached a saturated state of power. At this time, the charging dock executes the unlocking command of the corresponding charging control module to facilitate the user to take out the charging control module.

[0022] Optionally, after acquiring the power information of the charging control module of the fast charging group or the normal charging group, the method further includes: If there is no charging control module in the same group that has reached a saturated power state, sorting the multiple charging control modules in the same group according to the power information to generate a module sequence list of the charging control modules in the same group; Based on the module sequence table and the charging control module requirement information of the same group, an unlocking instruction is issued to the charging control module with the largest remaining power.

[0023] Through the above technical solution, during peak electricity consumption periods or concentrated charging time for new energy vehicles, there is a possibility that the power of the charging control modules in the charging dock has not reached saturation. At this time, the charging dock sorts the power of multiple charging control modules in the group required by the user, and generates a module sequence list, and sends an unlocking command to the charging control module with the most remaining power in the group required by the user.

[0024] Afterwards, before any charging control module reaches the saturated state, unlocking instructions of the charging control modules are issued one by one in the order of the module sequence list, so as to provide users with charging control modules with more remaining power, thereby providing users with longer charging time for new energy vehicles.

[0025] Optionally, after generating the module sequence list of the charging control modules in the same group, the method further includes: Obtain the user's vehicle power information through the user's mobile terminal; Based on the demand information of the charging control module, obtaining the charging power information of the fast charging module or the charging power information of the normal charging module; Calculate the estimated charging time of the vehicle according to the vehicle power information and charging power information; Calculating the remaining usage time of the multiple charging control modules in the same group based on the power information of the multiple charging control modules corresponding to the charging mode required by the user; Comparing the estimated charging time of the vehicle with the plurality of remaining usage times; If the estimated charging time of the vehicle is greater than or equal to the minimum remaining usage time in the same group, an unlocking instruction is sent to the charging control module with the largest remaining power in another group of charging control modules.

[0026] Through the above technical solution, after the user's mobile terminal and the charging dock establish information interaction, the charging dock can obtain the remaining power information of the user's vehicle through the mobile terminal. At the same time, based on the charging control module demand information sent by the user, the type of charging control module corresponding to the charging mode required by the user can be learned (i.e. fast charging or normal charging). Then the charging power of the charging control module to be taken out is also determined accordingly. At this time, the charging dock can calculate the estimated charging time of the vehicle based on the vehicle power information and the charging power of the charging control module.

[0027] The actual power consumption of the charging control module when executing a certain charging mode is certain, and the power of the charging control module when leaving the charging dock is also certain. At this time, the remaining usage time of the charging control module can be calculated, and the estimated charging time of the vehicle can be compared with the remaining usage time of multiple charging control modules in the group required by the user. It can be determined whether the power of the charging control module in the group required by the user is sufficient to support the end of charging.

[0028] If the power of the charging control modules in the group required by the user is not enough to support the completion of charging (that is, the estimated charging time of the vehicle is greater than or equal to the minimum remaining usage time in the same group), an unlocking command will be sent to the charging control module with the largest remaining power in another group of charging control modules, thereby providing the user's vehicle with a longer charging time and obtaining more electricity.

[0029] Optionally, after comparing the estimated charging time of the vehicle with the plurality of remaining usage times, the method further includes: If the estimated charging time of the vehicle is greater than or equal to the shortest remaining usage time in the same group, and the remaining usage time of multiple charging control modules in another group are all less than the shortest charging time of charging control modules in different groups, an unlocking command is issued to the charging control module with the longest remaining usage time in the fast charging group.

[0030] Through the above technical solution, if the estimated charging time of the vehicle is greater than or equal to the minimum remaining usage time of the same group (required group), and the remaining usage time of multiple charging control modules in another group is less than the shortest charging time of charging control modules in different groups (required groups), an unlocking command is issued for the maximum remaining usage time in the fast charging group, so that users can charge new energy vehicles through the charging control module of the fast charging group and obtain more electricity.

[0031] At the same time, the circulation frequency of the charging control module has been accelerated to facilitate charging of more new energy vehicles and improve the utilization efficiency of charging equipment.

[0032] Optionally, after the user places the charging control module unlocked by the charging dock into the charging interface device and inserts the charging gun into the vehicle, the method further includes: Obtain the user's vehicle power information and the real-time charging power information of the selected charging control module; Calculate and generate an estimated charging time based on the vehicle power information and the real-time charging power information; Calculate and generate an estimated remaining power based on the remaining usage time of the charging control module selected by the user and the estimated charging time; Reorder the charging interface device and the charging control modules in the charging dock to generate a module sequence table according to the estimated remaining power of the charging control module in the charging interface device and the power information of the charging control module in the charging dock; Based on the regenerated module sequence table, the required charging control module is matched for the user.

[0033] Through the above technical solution, after the user inserts the charging gun into the new energy vehicle, information interaction can be established between the charging control module and the new energy vehicle through the charging gun. At this time, the charging dock and the new energy vehicle can also exchange information through the charging gun and the charging control module, which enables the charging dock to obtain the power information and real-time charging power information of the new energy vehicle (since the grid voltage fluctuates within a certain range and the charging power is affected by environmental factors, the real-time charging power information is more accurate), and thus a more accurate estimate of the expected charging time of the new energy vehicle can be made.

[0034] Since the charging of the new energy vehicle is completed, the charging control module will also stop working. Therefore, the estimated charging time of the new energy vehicle is consistent with the remaining working time of the charging control module. At this time, the remaining power of the charging control module when the new energy vehicle is finished charging can be calculated, and the remaining power information of the charging control module can be obtained. The charging interface device and the charging control modules in the charging dock are reordered to generate a module sequence list, so as to match the required charging control module for the user and further enhance the user experience.

[0035] In summary, this application includes the following beneficial technical effects: 1. Separating and re-layout the core components of traditional charging piles effectively alleviates the impact of the strong binding of "car, pile, and position" on the charging of new energy vehicles, thus reducing the problem of new energy vehicles being unable to charge due to gasoline vehicles occupying space; 2. Since there is no need to equip each charging interface device with a charging control module, the charging control modules can be centrally managed through the charging dock, which effectively reduces the construction cost and operation and maintenance cost of the charging equipment; 3. By monitoring the real-time power of each charging control module, the logic for new energy vehicle owners to obtain the charging control module is optimized to improve the user experience.

[0044] The following is combined with Figure 1 -Attached Figure 7 This application is described in further detail.

[0045] The embodiments of the present application disclose a distributed charging pile system for a new energy vehicle and a control method for the distributed charging pile system for a new energy vehicle.

[0046] See attached Figure 1 , Attachment Figure 2 And attached Figure 3As shown, a distributed charging pile system for new energy vehicles includes a charging dock 1, a plurality of portable charging piles 2 and a charging interface device 4.

[0047] See attached Figure 1 and attached Figure 3 As shown, the charging interface device 4 is arranged at the rear of each new energy parking space 3, that is, the side of the parking space away from the vehicle passage. The charging interface device 4 can be a power-taking device for drawing out electric energy from the power grid. The charging interface device 4 can be understood as a "socket" lacking a conductive medium (that is, a portable charging pile 2 with a charging control module installed therein). After the new energy vehicle owner places the portable charging pile 2 into the charging interface device 4, the charging circuit in the charging interface device 4 can be connected, so that the user's vehicle can obtain electric energy from the power grid from the charging interface device 4.

[0048] See attached Figure 3 As shown, each charging interface device 4 is installed with a charging gun, the input end of the charging gun is installed on the charging interface device 4, the output end of the charging gun can interact with the new energy vehicle for electric energy, and the cable of the charging gun can be rolled up in the charging interface device 4.

[0049] See attached Figure 2 As shown, Figure 2 Only one charging dock 1 is shown in the figure. In actual scenarios, the number of charging docks 1 can be appropriately increased as the number of new energy parking spaces 3 increases. A display screen 11 is installed on the upper end of the charging dock 1, and two sides of the display screen 11 are provided with a QR code 12 for scanning by a user's mobile terminal.

[0050] See attached Figure 2 and attached Figure 3 As shown, the charging dock 1 is provided with several storage spaces, each of which is used to store an independent portable charging pile 2. The portable charging pile 2 is charged in the corresponding storage space and can be taken out of the storage space. Each storage space on the charging dock 1 is equipped with a unit door on the outside. The user opens the unit door by scanning the code on the mobile terminal to facilitate the access to the portable charging pile 2. The portable charging pile 2 is provided with a handle for easy picking and carrying, and a charging control module is provided in the portable charging pile 2 for adjusting the charging voltage and wireless information reception and transmission of the new energy vehicle.

[0051] The charging control module can be divided into a fast charging module and a normal charging module, that is, a charging control module for fast charging and a charging control module for normal charging. Users can choose according to the remaining power of the vehicle and the needs of vehicle use.

[0052] After the new energy vehicle owner drives the vehicle into the new energy parking space 3 equipped with a charging interface device 4, he scans the QR code 12 on the charging dock 1 through a mobile terminal such as a mobile phone or tablet, and selects a fast charging module or a normal charging module according to his own charging needs. The charging dock 1 matches and unlocks the corresponding charging control module for the user, and opens the corresponding unit door to facilitate the removal of the portable charging pile 2 from the charging dock 1.

[0053] Then, the user places the portable charging pile 2 into the charging interface device 4 at the rear of the new energy vehicle, and then inserts the output end of the charging gun into the new energy vehicle to charge the new energy vehicle.

[0054] The technical solution proposed in this application separates and re-layouts the core components of the traditional charging pile. On the one hand, when a gasoline vehicle occupies the new energy parking space 3, the charging interface device 4 corresponding to the parking space occupied by the gasoline vehicle is only one part of the charging equipment, and the charging control module as the main component is not occupied. The new energy vehicle owner places the charging control module in the charging interface device 4 to perform charging, which effectively alleviates the impact of the strong binding phenomenon of "vehicle, pile, and space" on the charging of new energy vehicles, and also reduces the problem of new energy vehicles being unable to charge due to the occupation of gasoline vehicles.

[0055] On the other hand, since there is no need to assemble a charging control module in each charging interface device 4, the charging control modules are centrally managed through the charging dock 1, which effectively reduces the construction cost and operation and maintenance cost of the charging equipment.

[0056] In addition, a charging module is provided in the portable charging pile 2, and the charging module can be a charging circuit or other independent power supply unit for the charging control module to obtain power from the power grid. The charging interface device 4 can provide power to the charging control module through the charging module, which reduces the possibility of charging interruption before the user's vehicle is fully charged, and also speeds up the circulation efficiency of the charging control module.

[0057] Based on the above-mentioned distributed charging pile system for a new energy vehicle, the present application also discloses a control method for the distributed charging pile system for a new energy vehicle, and the method is applied to the above-mentioned distributed charging pile system for a new energy vehicle.

[0058] The method will be described in detail below in conjunction with specific implementation methods.

[0059] Since the following text is mainly about the description of the charging control module and the charging dock 1, in order to avoid confusion of multiple concepts, the charging control module can be understood as the portable charging pile 2.

[0060] See attached Figure 4 As shown, a control method for a distributed charging pile system of a new energy vehicle includes the following steps: S101, module charging type, dividing multiple charging control modules into a fast charging group and a normal charging group.

[0061] In implementation, multiple charging control modules in the charging dock 1 are divided into a fast charging group and a normal charging group according to the charging type of the charging control module (i.e., fast charging or normal charging), so as to facilitate information acquisition and execution of subsequent steps.

[0062] The charging control modules are classified by their product model or related power information.

[0063] S102: Obtain charging control module demand information sent by the user's mobile terminal.

[0064] In implementation, after the user scans the QR code 12 on the charging dock 1 through a mobile terminal (such as a mobile phone), he enters the required charging type and other information on the mobile terminal or the display screen 11 of the charging dock 1, so that the charging dock 1 can obtain the user's demand information, including the required charging type, charging time, and the location of the vehicle, etc.

[0065] S103: Obtain power information of the charging control module of the fast charging group or the normal charging group according to the charging control module demand information.

[0066] In implementation, if the user inputs a requirement for a charging control module for fast charging, the charging dock 1 obtains the power information of the charging control module of the fast charging group so as to match a better charging control module for the user.

[0067] S104: Based on the power information of the charging control modules of the fast charging group or the normal charging group, if there is a charging control module in the corresponding group that has reached a saturated power state, an unlocking instruction is issued to the charging control module that has reached a saturated power state.

[0068] In implementation, in order to meet the electricity needs of all new energy vehicle owners as much as possible, according to the charging type required by the user, for example, the user needs a charging control module for fast charging, the charging dock 1 matches the user with a charging control module that has reached a saturated state in the fast charging group, which can provide the user's new energy vehicle with a sufficiently long charging time as much as possible.

[0069] Optional, see attached Figure 5 , after step S103, the following processing steps are also included: S201. If there is no charging control module that has reached a saturated power state among the charging control modules in the same group, sort the multiple charging control modules in the same group according to power information to generate a module sequence list of the charging control modules in the same group.

[0070] In implementation, when there is no charging control module that has reached the saturated power state in the group required by the user, multiple charging control modules in the group are sorted according to the power of the charging control modules in the same group, and a module sequence list of the charging control modules is generated, which is used as the basis for unlocking the charging control modules.

[0071] S202: Based on the module sequence list and charging control module requirement information of the same group, an unlocking instruction is issued to the charging control module with the largest remaining power.

[0072] In implementation, an unlocking command is sent to the charging control module with the most remaining power, so as to provide the user's vehicle with a longer charging time as possible.

[0073] Optional, see attached Figure 6 After step S201, the following processing may be performed: S301. Obtain the vehicle power information of the user through the user's mobile terminal.

[0074] In implementation, the user's mobile terminal and the charging dock 1 establish information interaction by scanning a code, after which the charging dock 1 can obtain the remaining power information of the user's vehicle.

[0075] S302: Based on the demand information of the charging control module, obtain the charging power information of the fast charging module or the charging power information of the normal charging module.

[0076] S303: Calculate the estimated charging time of the vehicle based on the vehicle power information and charging power information.

[0077] In practice, after the vehicle power information and the upcoming charging power information are known, the estimated charging time of the new energy vehicle can be calculated.

[0078] S304: Calculate the remaining usage time of multiple charging control modules in the same group based on the power information of multiple charging control modules corresponding to the charging mode required by the user.

[0079] In practice, when charging the new energy vehicle through the charging control module and the charging interface device 4, under ideal conditions, the operating power value of the charging control module is certain, then based on the remaining power of the charging control module and its operating power, the remaining usage time of the charging control module can be calculated.

[0080] S305: Compare the estimated charging time of the vehicle with a plurality of remaining usage times.

[0081] S306: If the estimated charging time of the vehicle is greater than or equal to the minimum remaining usage time in the same group, an unlocking instruction is sent to the charging control module with the largest remaining power in another group of charging control modules.

[0082] During implementation, if the power of the charging control modules in the group required by the user is not enough to support the completion of charging (that is, the estimated charging time of the vehicle is greater than or equal to the minimum remaining usage time of the same group), an unlocking command is sent to the charging control module with the largest remaining power in another group of charging control modules (the relevant power acquisition steps are the same as above, simplified here), thereby providing the user's vehicle with a longer charging time and obtaining more electricity.

[0083] This step is based on the fact that the charging time of another set of charging control modules can provide more power for new energy vehicles.

[0084] Optionally, after step S305, the following processing steps are further included: If the vehicle's estimated charging time is greater than or equal to the shortest remaining usage time in the same group, and the remaining usage time of multiple charging control modules in another group is less than the shortest charging time of charging control modules in different groups, an unlocking command will be issued to the charging control module with the longest remaining usage time in the fast charging group.

[0085] In implementation, when the estimated charging time of the vehicle is greater than or equal to the minimum remaining usage time of the same group required by the user (such as the fast charging group), and the remaining usage time of multiple charging control modules in another group (such as the normal charging group) are all less than the shortest charging time of charging control modules in different groups (fast charging groups), then an unlocking command is issued to the charging control module with the longest remaining usage time in the fast charging group. This will enable the customer's vehicle to obtain more electricity and improve the user experience.

[0086] Optional, see attached Figure 7 As shown, when the user places the unlocked charging control module of the charging dock 1 into the charging interface device 4 and inserts the charging gun into the vehicle, it also includes: S401. Obtain the user's vehicle power information and the real-time charging power information of the selected charging control module.

[0087] During implementation, the user takes out the charging control module from the charging dock 1, inserts the charging control module into the charging interface device 4, and inserts the charging gun into the new energy vehicle. Then, the charging dock 1 and the new energy vehicle can exchange information through the charging gun and the charging control module.

[0088] S402: Calculate and generate an estimated charging time based on the vehicle power information and the real-time charging power information.

[0089] In implementation, since the grid voltage fluctuates within a certain range and the charging power is affected by environmental factors, the charging dock 1 can obtain the power information and real-time charging power information of the new energy vehicle through the charging gun. Compared with obtaining the remaining power of the vehicle through the user's mobile terminal, the expected charging time of the new energy vehicle can be calculated more accurately.

[0090] S403: Calculate and generate an estimated remaining power based on the remaining usage time and the estimated charging time of the charging control module selected by the user.

[0091] In practice, since the charging of the new energy vehicle is completed, the charging control module also stops working. Therefore, the estimated charging time of the new energy vehicle is consistent with the remaining working time of the charging control module.

[0092] The estimated charging time is subtracted from the remaining usage time of the charging control module to obtain the estimated remaining usage time after charging is completed, that is, how long the charging module can still perform charging, and then the estimated remaining power corresponding to the estimated remaining usage time is calculated, so that the charging dock 1 can uniformly manage and plan multiple charging control modules.

[0093] S404 , reorder the charging control modules in the charging interface device 4 and the charging dock 1 to generate a module sequence table according to the estimated remaining power of the charging control modules in the charging interface device 4 and the power information of the charging control modules in the charging dock 1 .

[0094] In implementation, the charging control module currently in the charging dock 1 and the charging control module outside the charging dock 1 (i.e., the charging control module placed in the charging interface device 4) are reordered according to the remaining power. Here, the remaining power of the charging control module refers to the remaining power after the new energy vehicle is charged, and the other part refers to the power result of charging the charging control module in the charging dock 1, so as to regenerate the module sequence list.

[0095] S405: Match the required charging control module for the user based on the regenerated module sequence table.

[0096] In implementation, all charging control modules in the charging dock 1 and the charging interface device 4 are uniformly included in the sample range that matches the user's charging control module requirements, thereby providing users with better charging control modules and further improving the user experience.

[0097] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in turn. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
