[0002] With the application and popularization of electric vehicles, the types of supporting facilities (such as charging piles) for electric vehicles are also increasing, and the charging interfaces are also different.

Furthermore, the adapter is prone to falling off or being lost, affecting the next user who needs to use it. It cannot intelligently identify the user's needs, nor can it control the vehicle charging, resulting in the vehicle charging effect failing to meet the user's requirements. Summary of the Invention

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0054] This invention provides a reference Figure 1 , Figure 1 This is a schematic diagram of the first embodiment of the charging management system of the present invention.

[0055] In this embodiment, the charging management system 1 includes: a data acquisition device 10, a control device 20, a charging conversion device 30, and a response device 40. The control device 20 is connected to the data acquisition device 10, the charging conversion device 30, and the response device 40, respectively. The response device 40 includes a locking mechanism 401.

[0056] It should be understood that the control device 20 is connected to the data acquisition device 10, the charging conversion device 30, and the response device 40, respectively. The control device 20 can receive charging information or generate corresponding control commands to control the devices connected to it. The charging conversion device 30 and the response device 40 together constitute a charging pile.

[0057] In a specific implementation, the data collection device 10 can be used to collect charging information, which may include user information, vehicle information, etc. This embodiment does not impose any restrictions on this.

[0058] In this embodiment, the acquisition device 10 is used to acquire charging information and send the charging information to the control device 20.

[0059] It should be noted that the data collection device 10 is used to collect charging information, which includes vehicle information. Specifically, when a vehicle enters the charging area, the vehicle is scanned to obtain the charging information.

[0060] The charging area refers to the area where vehicles are parked, defined by the location of charging piles. The data acquisition device 10 can be positioned above the charging piles to scan vehicles entering the charging area in real time and obtain vehicle information. The data acquisition device 10 can be a camera, image sensor, or other device that scans data; this embodiment does not impose any limitations on this.

[0061] It should be understood that the charging information also includes user information. The collection device 10 is also used to collect user information and send it to the control device 20. When the user drives the vehicle into the charging area, the collection device 10 also collects user information and sends it to the control device 20. The user information may include the terminal used by the user, such as the user's mobile phone, smartwatch, etc. This example does not limit this, and the identification of mobile phones or smartwatches is not limited to Bluetooth, NFC, and positioning.

[0062] In a specific implementation, the data acquisition device 10 may include a camera, which can capture vehicle information or user information and send the vehicle information or user information to the control device 20.

[0063] In this embodiment, the control device 20 is used to determine the target charging gun head according to the charging information, and generate corresponding control commands to the charging conversion device 30 and the response device 40 based on the target charging gun head.

[0064] It should be noted that after receiving the vehicle information sent by the acquisition device 10, the control device 20 can analyze the vehicle information to determine the corresponding target charging gun. The control device 20 can be a server, which analyzes the vehicle information. For example, the server stores preset vehicle information, including the vehicle type and the corresponding charging interface type. Therefore, when the server receives the vehicle information, it compares the vehicle information with the preset vehicle information to determine the charging interface type of the vehicle that needs to be charged, thereby determining the target charging gun. For example, if the vehicle's charging interface is a single-port type, the corresponding charging gun is the main charging gun. Then, the control device 20 determines the target charging gun as the main charging gun and generates control commands based on the target charging gun to the charging conversion device 30 and the response device 40.

[0065] In this embodiment, the locking mechanism 401 is used to unlock the charging gun head in the charging conversion device 30 according to the control command.

[0066] It should be noted that the charging station has a socket for inserting the charging gun head, and the socket is equipped with a locking mechanism 401 to limit the movement of the charging gun head, thereby locking or unlocking the charging gun head through the locking mechanism 401.

[0067] The charging gun head is used to charge the vehicle. It has at least two types of connectors to allow for different charging methods. The charging gun head includes a main gun head and multiple sub-gun heads. The sub-gun heads are located at the front end of the main gun head, and multiple sub-gun heads can be inserted sequentially into the front end of the main gun head. The main gun head and the sub-gun heads can be of the same or different types. For example, the main gun head can be an AC charging gun head, and the sub-gun heads can be all DC charging gun heads, all AC charging gun heads, or a combination of both. This embodiment does not impose any limitations on these types. The number of sub-gun heads can be 3, 5, etc., and this embodiment does not impose any limitations on this number.

[0068] Since a charging gun consists of multiple charging heads, the charging type can be a single DC port, a single AC port, or a dual AC / DC port, and the specifications of the charging heads include Chinese standard, European standard, and American standard charging heads. Once the charging type of the vehicle is determined, the corresponding charging head can be selected to charge the vehicle.

[0069] The charging conversion device 30 is used to determine the corresponding charging gun head according to the control command, and control the charging gun head to enter the corresponding charging mode to charge the vehicle.

[0070] In practice, after the control device 20 generates a control command for the target charging gun, it sends the control command to the charging conversion device 30. The charging conversion device 30 determines the charging gun that needs to charge the vehicle according to the control command, and then controls the charging gun to enter the corresponding charging mode to charge the vehicle.

[0071] This embodiment solves the problem of compatibility between different charging interfaces by setting up a data acquisition device 10, a control device 20, a charging conversion device 30, and a response device 40 in the charging management system 1. The control device 20 is connected to the data acquisition device 10, the charging conversion device 30, and the response device 40, and the response device 40 includes a locking mechanism 401. The data acquisition device 10 is used to collect charging information and send the charging information to the control device 20. The control device 20 is used to determine the target charging gun based on the charging information and generate corresponding control commands to the charging conversion device 30 and the response device 40 based on the target charging gun. The locking mechanism 401 is used to unlock the charging gun in the charging conversion device 30 according to the control commands. The charging conversion device 30 is used to determine the corresponding charging gun according to the control commands and control the charging gun to enter the corresponding charging mode to charge the vehicle. This solves the problem of compatibility between different charging interfaces, provides high reliability for multiple charging guns, eliminates the need for users to carry conversion guns, automatically identifies or confirms the charging method before charging the vehicle, and prepares the corresponding charging interface in advance, making it convenient and quick to use.

[0072] refer to Figure 2 , Figure 2 This is a schematic diagram of the second embodiment of the charging management system of the present invention.

[0073] Based on the first embodiment described above, the response device 40 in the charging management system 1 of this embodiment further includes: a display device 402 and a voice playback device 403; the display device 402 is used to display the charging status of the vehicle, and displays an idle status after the vehicle has finished charging; the voice playback device 403 is used to prompt the user to charge, and prompt the user to return the charging gun head to its original position after charging has finished.

[0074] It should be noted that the display device 402 may specifically include a display screen, indicator lights, etc. The display screen shows the charging status of the vehicle or the usage status of the charging pile, etc. After the vehicle has finished charging, the display screen will show that it is in an idle state. The indicator lights may be located on the charging gun head. When the vehicle is charging with the charging gun head, the corresponding indicator light on the charging gun head will light up, and the indicator light will turn off after use.

[0075] The voice playback device 403 is used to prompt the user to charge the vehicle. For example, if the user drives the vehicle into the charging area for more than a set time but does not charge it, the voice playback device 403 will prompt the user to charge. After charging is complete, the user will be prompted to return the charging gun to its original position. The voice playback device 403 can be a speaker, audio system, etc., and this embodiment does not limit this.

[0076] Understandably, after charging is complete, the control device 20 can activate the corresponding locking mechanism 401 to reliably fix the charging gun head. The control device 20 stores the charging information for easy identification of the charging method during the next charging session.

[0077] This embodiment improves the user experience by setting a display device 402 and a voice playback device 403 in the response device 40. The display device 402 is used to display the charging status of the vehicle and to display an idle status after the vehicle has finished charging. The voice playback device 403 is used to prompt the user to charge and to prompt the user to return the charging gun to its original position after charging is completed. By intelligently displaying the charging status of the vehicle and the status of the charging pile, the user experience is improved.

[0078] This invention provides a charging management method, referring to... Figure 3 , Figure 3 This is a flowchart illustrating the first embodiment of the charging management method of the present invention.

[0079] In this embodiment, the charging management method is applied to the charging management system described above. The charging management system includes a data acquisition device, a control device, a charging conversion device, and a response device. The method includes the following steps:

[0080] Step S10: The acquisition device acquires charging information and sends the charging information to the control device.

[0081] It should be noted that the executing entity in this embodiment can be a charging management system, or other systems that can achieve the same or similar functions. This embodiment does not limit this; the charging management system is used as an example for illustration.

[0082] It should be understood that the control device in the charging management system is connected to the data acquisition device, the charging conversion device, and the response device, respectively. The control device can receive charging information or generate corresponding control commands to control the devices connected to it. The charging conversion device and the response device together constitute the charging pile.

[0083] It should be noted that the data collection device is used to collect charging information, which includes vehicle information. Specifically, when a vehicle enters the charging area, the device scans the vehicle to obtain the charging information.

[0084] The charging area refers to the designated charging zone for vehicles, defined by the location of charging stations. A data acquisition device can be positioned above the charging stations to scan vehicles entering the charging area in real time and obtain vehicle information. The data acquisition device can be a camera, image sensor, or any other device that scans data; this embodiment does not impose any limitations on this.

[0085] It should be understood that the charging information also includes user information. The collection device is also used to collect user information and send it to the control device. When a user drives the vehicle into the charging area, the collection device also collects user information and sends it to the control device. The user information may include the user's terminal, such as the user's mobile phone, smartwatch, etc. This example does not limit this, and the identification of mobile phones or smartwatches is not limited to Bluetooth, NFC, and positioning.

[0086] In practice, the data collection device may include a camera, which captures vehicle or user information and sends the information to the control device.

[0087] Step S20: The control device determines the target charging gun head based on the charging information, and generates corresponding control commands to the charging conversion device and the response device based on the target charging gun head.

[0088] It should be noted that after receiving the vehicle information sent by the data acquisition device, the control device can analyze the vehicle information and determine the corresponding target charging gun.

[0089] The control device can be a server, which analyzes vehicle information. For example, the server stores preset vehicle information, including vehicle type and corresponding charging interface type. Therefore, when the server receives vehicle information, it compares the vehicle information with the preset vehicle information to determine the charging interface type of the vehicle that needs to be charged, thereby determining the target charging gun. For example, if the vehicle's charging interface is a single-port type, the corresponding charging gun is the main charging gun. The control device then determines the target charging gun as the main charging gun and generates control commands based on the target charging gun to the charging conversion device and the response device.

[0090] Step S30: The response device unlocks the charging gun head in the charging conversion device according to the control command.

[0091] In practice, the response device includes a locking mechanism that can unlock the charging gun head in the charging conversion device according to control commands.

[0092] For example, a charging gun head includes a main head A, a first sub-head A1, a second sub-head A2, and a third sub-head A3. If the target charging gun head is the main head A, the locking mechanism locks the first sub-head A1, the second sub-head A2, and the third sub-head A3, allowing only the main head A to be pulled out. If the target charging gun head is the second sub-head A2, the third sub-head A3 is locked, and the main head A, the first sub-head A1, and the second sub-head A2 are fixed to the same body and can be pulled out simultaneously.

[0093] It should be noted that the charging station has a socket for inserting the charging gun head, and the socket has a locking mechanism to limit the movement of the charging gun head, thereby locking or unlocking the charging gun head through the locking mechanism.

[0094] When a control command is received, the corresponding locking mechanism trips. The tripping command can be sent periodically and continuously. After the locking mechanism performs the corresponding action, it generates locking feedback. When the tripping command and the locking feedback are consistent, the tripping is successful. If the tripping command and the locking feedback are inconsistent, the control device is reported to have a locking mechanism malfunction.

[0095] The charging gun head is used to charge the vehicle. It has at least two types of connectors to allow for different charging methods. The charging gun head includes a main gun head and multiple sub-gun heads. The sub-gun heads are located at the front end of the main gun head, and multiple sub-gun heads can be inserted sequentially into the front end of the main gun head. The main gun head and the sub-gun heads can be of the same or different types. For example, the main gun head can be an AC charging gun head, and the sub-gun heads can be all DC charging gun heads, all AC charging gun heads, or a combination of both. This embodiment does not impose any limitations on these types. The number of sub-gun heads can be 3, 5, etc., and this embodiment does not impose any limitations on this number.

[0096] Since a charging gun consists of multiple charging heads, the charging type can be a single DC port, a single AC port, or a dual AC / DC port, and the specifications of the charging heads include Chinese standard, European standard, and American standard charging heads. Once the charging type of the vehicle is determined, the corresponding charging head can be selected to charge the vehicle.

[0097] Step S40: The charging conversion device determines the corresponding charging gun head according to the control command, and controls the charging gun head to enter the corresponding charging mode to charge the vehicle.

[0098] In practice, after the control device generates a control command for the target charging gun, it sends the control command to the charging conversion device. The charging conversion device determines the charging gun that needs to charge the vehicle based on the control command, and then controls the charging gun to enter the corresponding charging mode to charge the vehicle.

[0099] Furthermore, after the charging gun finishes charging the vehicle, the status of this charging area needs to be updated in a timely manner to facilitate other users charging their vehicles. Therefore, after step S40, the method further includes: detecting the dwell time of the vehicle after charging is completed; when the dwell time is greater than a preset limit time, the control device controls the display device in the response device to display an idle state.

[0100] It should be noted that when the charging is completed, the dwell time of the vehicle in the charging area can be detected. By setting a time threshold in advance, i.e., a preset time limit, such as 1 minute, 3 minutes, etc., this embodiment does not impose any restrictions on this. The charging is completed when the vehicle is fully charged or when the user stops charging.

[0101] In practice, when a vehicle enters the charging area but fails to charge for more than a preset time limit, the control device controls the display device in the response device to show an idle state.

[0102] When the vehicle's dwell time exceeds the preset limit, the charging conversion device automatically returns to an idle state and controls the display device in the response device to show an idle state. The display device can be a screen, which displays the status of the corresponding charging gun head.

[0103] In practical implementation, when the user's charging is detected to be complete, the voice playback device in the response device can be controlled to prompt the user to insert the charging gun head into the socket for return to its original position. Otherwise, the next charging will not start normally. The display device can also prompt the user to return the charging gun head to its original position. After the charging gun head is returned to its original position, the control device detects the return signal and activates the corresponding locking mechanism to reliably fix the charging gun head in place.

[0104] In practice, after each charging session, the control device records the charging information locally, including the vehicle model, license plate information, and user information. During the next charging session, the charging method can be directly identified through the data collection device without uploading to the cloud. This also avoids the need to determine the target charging gun based on the saved charging information when there is no network connection or when the user has not sent a request.

[0105] This embodiment collects charging information through the acquisition device and sends the charging information to the control device. The control device determines the target charging gun based on the charging information and generates corresponding control commands to the charging conversion device and the response device based on the target charging gun. The response device unlocks the charging gun in the charging conversion device according to the control commands. The charging conversion device determines the corresponding charging gun according to the control commands and controls the charging gun to enter the corresponding charging mode to charge the vehicle. This solves the problem of compatibility between different charging interfaces, provides high reliability for multiple charging guns, eliminates the need for users to carry conversion guns, automatically identifies or confirms the charging method before charging the vehicle, and prepares the corresponding charging interface in advance, making it convenient and quick to use.

[0106] refer to Figure 4 , Figure 4 This is a flowchart illustrating the second embodiment of the charging management method of the present invention.

[0107] Based on the first embodiment of the charging management method described above, step S20 of the charging management method in this embodiment specifically includes:

[0108] Step S201: The control device obtains vehicle model information based on the charging information, compares the vehicle model information with preset vehicle model information, and determines the charging type.

[0109] It should be noted that the control device can be a server, which can collect model data of currently available car models in advance and store them as preset car model information.

[0110] The model data includes the charging current type or charging gun specifications corresponding to the vehicle model. The charging current type includes single DC port, single AC port, and AC / DC dual port. The charging gun specifications include Chinese standard gun, European standard gun, American standard gun, etc.

[0111] The control device analyzes the charging information to obtain vehicle model information, and compares the vehicle model information with preset vehicle model information to determine the charging type. For example, if the vehicle model information is model T, the corresponding charging type is single DC port.

[0112] Step S202: The control device determines the target charging gun head according to the charging type, and generates corresponding control commands to the charging conversion device and the response device based on the target charging gun head.

[0113] In practical implementation, once the charging type is obtained, the target charging gun head in the charging gun head can be determined according to the charging type. For example, the charging gun head includes the main gun head A, the first sub-gun head A1, the second sub-gun head A1 and the third sub-gun head A3. The determined target charging gun head is the main gun head A. Then, the control command of the main gun head A can be generated based on the main gun head A and sent to the charging conversion device and the response device.

[0114] Optionally, since the charging type can be a single DC port, a single AC port, or a dual AC / DC port, the single-port charging head can be directly determined based on the vehicle model information, but the confirmation of the dual-port charging head may not be accurate. Therefore, it is possible to first identify whether the charging type is a single port or a dual port. The step of "the control device determines the target charging head according to the charging type" specifically includes: A': When the charging type is single-port charging, the control device determines the charging current according to the vehicle model information and determines the target charging head according to the charging current.

[0115] It should be noted that when the charging type is single-port charging, the charging current can be determined directly based on the vehicle model information, and the target charging gun can be determined based on the charging current. For example, if the main charging gun A is a DC gun and the determined charging current is DC, then the target charging gun can be determined as the main charging gun A based on the DC charging current.

[0116] Furthermore, when the charging type is dual-port charging, the specific steps for determining the target charging gun head include: when the charging type is dual-port charging, the control device obtains license plate information and / or user information based on the charging information; the control device queries historical charging records based on the license plate information and / or the user information, and determines the target charging gun head based on the historical charging records.

[0117] It should be understood that when the charging type is dual-port charging, the charging information may also contain license plate information and / or user information. In such cases, the license plate information and / or user information can be obtained from the charging information. For example, if the charging information only contains license plate information, the control device can query historical charging records based on the license plate information to find the charging gun used by the current vehicle in those historical records, thereby determining the target charging gun. Historical charging records store information such as the charging type and charging time for different license plates and different users.

[0118] In practice, if user information is present in the charging information, the corresponding charging gun used by the user can be queried in the historical charging records based on the user information, thereby determining the target charging gun.

[0119] If the charging information includes license plate information and user information, historical charging records can be queried based on the license plate information and user information to obtain the corresponding charging gun.

[0120] The control device can recommend the charging gun head that the user last used based on license plate information and / or user information.

[0121] In this embodiment, the control device obtains vehicle model information based on the charging information, compares the vehicle model information with preset vehicle model information, and determines the charging type. The control device determines the target charging gun based on the charging type and generates corresponding control commands to the charging conversion device and the response device based on the target charging gun. By collecting vehicle model information from the acquisition device, the corresponding target charging gun can be quickly determined based on the vehicle model information, the charging method can be confirmed in advance, and the user experience can be improved.

[0122] Based on the first and second embodiments of the charging management method described above, a third embodiment of the charging management method of the present invention is proposed.

[0123] The charging management method in this embodiment, after the step "the control device queries historical charging records based on the license plate information and / or the user information", further includes:

[0124] Step B1: When the information in the historical charging record is inconsistent with the license plate information or the user information, the target charging amount of the vehicle is determined by the data acquisition device.

[0125] It should be understood that if a user owns multiple vehicles, when the user is charging other vehicles, the control device may compare the charging information with historical charging records, which may not be consistent. In this case, the charging gun needs to be displayed to inform the user to make a selection and to charge the charging gun according to the current load, peak and off-peak electricity consumption, and electricity cost.

[0126] If the information in the charging record is inconsistent with the license plate information or user information, the data collection device can determine the target charging amount of the vehicle. The target charging amount refers to the maximum charging amount Q1 of the vehicle model that needs to be charged.

[0127] Step B2: Determine the amount of charge the vehicle needs to be made based on the target charging amount.

[0128] In practice, the amount of charge to be charged for the vehicle is calculated as 80% of the target charge amount, and the amount of charge to be charged is Q2 = Q1 * 80%.

[0129] Step B3: Obtain the current electricity consumption period and the current electricity unit price.

[0130] It should be noted that the current electricity consumption period can be either peak or off-peak. The unit price of electricity varies in different periods, so the current unit price of electricity can also be obtained.

[0131] Step B4: Calculate the electricity cost required to fully charge each charging gun based on the current electricity consumption period and the current electricity unit price.

[0132] It should be understood that the electricity cost required to fully charge each charging gun can be calculated based on the current electricity usage period and the current electricity price.

[0133] In practice, if the current electricity consumption period is always during peak hours, the time required to fully charge the amount to be charged can be calculated based on the charging power of each charging gun. Then, the electricity cost required to fully charge the amount to be charged for each charging gun can be calculated based on the time and the peak electricity price multiplied by 1.

[0134] If the current electricity consumption period is consistently during off-peak hours, the time required to fully charge the device can be calculated based on the charging power of each charging gun. Then, the electricity cost required to fully charge the device can be calculated based on the time and the off-peak electricity price multiplied by 2.

[0135] If the current electricity consumption period is peak but short, and enters off-peak season after peak hours, the remaining time of the peak period can be calculated, along with the amount of electricity charged during this time. The first electricity cost for charging during peak hours can be calculated, along with the remaining amount of electricity charged during the peak period and the amount to be charged. The time required to fully charge the remaining amount during off-peak hours can be calculated, along with the second electricity cost for charging during off-peak hours. Finally, the electricity cost to fully charge the remaining amount can be calculated based on either the first or second electricity cost. Similarly, if the current electricity consumption period is off-peak, and enters peak season after off-peak hours, the total electricity cost to fully charge the remaining amount can be calculated by subtracting the off-peak and peak hours.

[0136] Step B5: Select the charging gun corresponding to the lowest electricity cost among the electricity costs as the target charging gun.

[0137] In practice, after calculating the electricity cost required to fully charge each charging gun, the electricity costs can be sorted, and the charging gun with the lowest cost can be selected as the target charging gun. This target charging gun is then recommended to the user.

[0138] This embodiment determines the target charging amount of a vehicle by means of a data acquisition device when the information in the historical charging record is inconsistent with the license plate information or the user information; determines the amount of electricity to be charged based on the target charging amount; obtains the current electricity consumption period and the current electricity price; calculates the electricity cost required to fully charge the amount of electricity to be charged for each charging gun based on the current electricity consumption period and the current electricity price; and selects the charging gun with the lowest electricity cost as the target charging gun. It can intelligently calculate the charging method with the lowest electricity cost based on the current electricity consumption and obtain the corresponding charging gun, recommending this charging gun to the user to improve the effectiveness of charging management.

[0139] refer to Figure 5 , Figure 5 This is a flowchart illustrating the fourth embodiment of the charging management method of the present invention.

[0140] Based on the first embodiment of the charging management method described above, the charging management method in this embodiment further includes, after step S20:

[0141] Step S21: The control device detects whether it has received the user's request information.

[0142] It should be noted that after the control device sends the control command to the response device and the charging conversion device, the response device will unlock the corresponding charging head according to the control command, and the charging conversion device will control the corresponding charging head to enter the charging mode. However, the user may change the charging method, so the control device will detect whether it has received the user's request information to determine whether the charging head needs to be changed.

[0143] In practice, the user's demand information refers to the user actively sending the desired charging gun head to the server. This demand information has a higher priority than the target charging gun head determined by the control device based on the charging information.

[0144] Step S22: Upon receiving the demand information, determine the target charging gun head to be updated based on the demand information, and generate corresponding control commands to the charging conversion device and the response device based on the target charging gun head to be updated.

[0145] Optionally, when the control device receives the demand information sent by the user, it can analyze the demand information to determine the updated target charging head. The updated target charging head refers to the charging head that the user wants to use. Based on the updated target charging head, a corresponding control command is generated and sent to the charging conversion device and the response device. When the response device receives this control command, it unlocks the updated target charging head corresponding to this control command and locks the previously unlocked target charging head. Alternatively, the previously unlocked target charging head can be locked first, and then unlocked according to the target charging head corresponding to the control command. The locking and unlocking steps are not limited.

[0146] When the charging conversion device receives the corresponding control command for the updated target charging head, it stops the charging mode of the previous target charging head and controls the updated target charging head to enter the charging mode.

[0147] Optionally, the user's demand information can also be sent to the control device before the control device receives the charging information sent by the data acquisition device. For example, the user drives the vehicle to the charging area and sends the demand information to the control device.

[0148] After the collection device collects charging information and sends the charging information to the control device, the method further includes: the control device detecting whether it receives user demand information; and when it receives the demand information, determining the target charging gun head based on the demand information.

[0149] It should be noted that after the control device receives the charging information, it also checks whether it receives the user's demand information. If the demand information is received, the target charging gun is determined based on the demand information, and the target charging gun can be unlocked directly based on the user's demand information.

[0150] In practice, if the control device does not receive the user's demand information, it determines the target charging gun based on the charging information and unlocks the target charging gun.

[0151] In this embodiment, the control device detects whether it receives user request information. When the request information is received, the target charging gun head is determined to be updated based on the request information, and corresponding control commands are generated to the charging conversion device and the response device based on the updated target charging gun head. The target charging gun head that the user wants to use is unlocked directly according to the user's request information, which improves the interaction between the user and the control device, thereby preparing the corresponding charging interface in advance according to the target charging gun head.
