[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0047] It should be noted that the terms "first", "second", "third", "fourth", etc. in the description and claims of this application are used to distinguish different objects, rather than to describe a specific order. The terms "include" and "have" in the embodiments of this application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0048] The charging pile device disclosed in the embodiments of this application can be a home charging pile, a super charging pile, or a charging pile in a public operation charging station, etc. That is, this application is applicable to the application environment of home charging piles, and also applicable to the application environment of super charging piles or public operation charging stations. Therefore, the embodiments of this application disclose a method, device, equipment, system, and storage medium for controlling a vehicle charging port cover, which can help an electric vehicle accurately locate whether it is its own charging, and at the same time can also reduce the probability of mis-opening the cover by passing vehicles or queuing vehicles, and improve the accuracy of opening the charging port cover. Among them, for an electric vehicle, it detects whether it receives a first broadcast message. The first broadcast message at least includes a first indication and a second indication. The first indication is used to indicate that the first broadcast message is a specific broadcast, and the second indication is an instruction used to indicate the electric vehicle to open the charging port cover. When it is determined that the first broadcast message is received, it judges whether the electric vehicle currently meets the opening condition of the charging port cover. When the opening condition is met, the charging port cover of the electric vehicle is opened. Among them, the electric vehicle can accurately locate whether it needs to open the charging port cover according to these convergence conditions such as the first indication, the second indication, and the opening condition, and avoid mis-opening the cover; for the charging pile device, it detects whether it receives a charging trigger signal. When the charging trigger signal is detected, it generates a first broadcast message. The first broadcast message includes a first indication and a second indication. The first indication is used to indicate that the first broadcast message is a specific broadcast, and the second indication is used to indicate the electric vehicle to open the charging port cover, and broadcasts the first broadcast message. Among them, the charging pile device does not need to be bound to the electric vehicle. As long as the charging trigger signal is detected, it sends the first broadcast message including the first indication and the second indication, which can enable the electric vehicle to detect whether it needs to open the charging port cover according to the first indication and the second indication, and improve the accuracy of opening the charging cover.

[0049] The technical solution of this application will be introduced in detail through specific embodiments below.

[0050] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the method for controlling a vehicle charging port cover disclosed in Embodiment 1 of this application; Figure 1 Applied to a charging pile device, the method for controlling a vehicle charging port cover may include:

[0051] The charging pile device detects whether a charging trigger signal is received. Among them, when the charging trigger signal is detected, step 102 is executed; when the charging trigger signal is not detected, this process ends.

[0052] Exemplarily, the charging pile device provided in the embodiment of the present application generally includes a pile main body, an upper gun seat, and a charging gun. The upper gun seat is arranged on the pile main body, and a plug-in position for the charging gun to be inserted and removed is arranged on the upper gun seat. The charging gun is connected to the circuit structure inside the pile main body and is used to be inserted into an electric vehicle (for example, an electric car) for charging and discharging. Correspondingly, an insertion port for inserting the charging gun for charging is also arranged in the electric vehicle, and a charging port cover that can be opened or closed is arranged outside the insertion port. The charging port cover is opened during charging to facilitate inserting the charging gun into the inner insertion port, and when not charging, the upper charging port cover is closed to protect the insertion port, such as dust and water prevention. Further, a travel switch for triggering charging can be arranged on the upper gun seat, or a switch for triggering charging can be arranged on the charging gun, or charging can be triggered by removing the charging gun.

[0053] Among them, the charging trigger signal is used to indicate to the charging pile device that an electric vehicle needs to use the charging pile device for charging, and it is necessary to notify the electric vehicle and make it automatically open the charging port cover. Correspondingly, optionally, the charging trigger signal in the embodiment of the present application includes an operation signal when the charging switch on the charging pile device is operated or a gun removal signal when the charging gun is removed. Further, the operation signal when the charging switch is operated can be the signal generated when the above-mentioned travel switch is pressed or the signal generated when the switch on the charging gun is pressed, and the gun removal signal is the signal detected when the user manually removes the charging gun from the upper gun seat.

[0054] Furthermore, in step 101, the charging pile device detects the charging trigger signal. When the charging trigger signal is detected, step 102 is executed; when the charging trigger signal is not detected, this process ends. It should be further noted that after this process ends when the charging trigger signal is not detected, it will enter the next process and continue to execute step 101, which can also be considered as continuing to execute step 101.

[0055] 102. The charging pile device generates first broadcast information, which includes a first indication and a second indication. Among them, the first indication is used to indicate that the first broadcast information is a specific broadcast, and the second indication is an instruction for indicating the electric vehicle to open the charging port cover.

[0056] In step 102, the first broadcast message includes a first indication and a second indication. The first indication is used to indicate that the first broadcast message is a specific broadcast, that is, the first indication indicates that the first broadcast message is a special message for sending an instruction for instructing an electric vehicle to open a charging port cover, rather than other service-type information. The second indication is an instruction specifically for instructing the electric vehicle to open the charging port cover. That is to say, the electric vehicle can determine that the first broadcast message is a specific broadcast based on the first indication, and then further obtain the second indication in the first broadcast message. According to the second indication, an instruction for clearly indicating to open the charging port cover can be obtained.

[0057] Optionally, the first indication and the second indication can be the content pre-agreed between the charging pile device and the electric vehicle to ensure the synchronization of information cognition between the two. For example, the first indication and the second indication can be the content of a standard communication protocol, which are respectively written into the communication protocol before the charging pile device and the electric vehicle leave the factory, or synchronized later through the update of the communication protocol software. It can be understood that since there is no prior binding between the charging pile device and the electric vehicle, in the embodiment of the present application, the charging pile device does not know which electric vehicle needs to be charged. After detecting a charging trigger signal, the first broadcast message including the first indication and the second indication is sent, so that the electric vehicle that needs to be charged can determine the specific broadcast from several broadcast messages according to the first indication, and then further open the charging port cover according to the second indication. The electric vehicle can accurately locate itself, improve the accuracy of opening the charging port cover, and also reduce the binding process, improving the user experience.

[0058] 103. The charging pile device broadcasts the above first broadcast message.

[0059] Optionally, the charging pile device broadcasts through a wireless network. For example, wireless networks such as Bluetooth, WiFi, ZigBee, radio frequency, and USB. Taking Bluetooth as an example, a Bluetooth module is set in the charging pile device, so that the charging pile device is equipped with Bluetooth functions, can support most function characteristics such as BLE4.2 and BLE5, and the charging pile device operates in the slave mode to broadcast the first broadcast message.

[0060] Therefore, in the above embodiments, for the charging pile device, after detecting a charging trigger signal, it generates a first broadcast message including a first indication and a second indication. The first indication indicates that the first broadcast message is a specific broadcast, and the second indication is an instruction for instructing the electric vehicle to open the charging port cover. Then, it broadcasts the first broadcast message. The entire process does not require the electric vehicle to be bound to the charging pile device. The charging pile device notifies the electric vehicle to charge by broadcasting the first broadcast message including the first indication and the second indication, enabling the electric vehicle to detect whether it needs to open the charging port cover according to the first indication and the second indication, achieving automatic opening of the cover, improving the accuracy of opening the charging cover, helping the electric vehicle accurately locate whether it is its own charging, and at the same time reducing the probability of passing vehicles or queuing vehicles accidentally opening the cover.

[0061] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of the vehicle charging port cover control method disclosed in the second embodiment of the present application; Figure 2 Applied to the charging pile device, the vehicle charging port cover control method may include:

[0062] 201. When the charging pile device broadcasts the second broadcast message, it detects whether it receives a charging trigger signal. Among them, when detecting the charging trigger signal, it executes step 202 and step 207. When not detecting the charging trigger signal, it ends this process.

[0063] Among them, the charging trigger signal is used to indicate that there is an electric vehicle that needs to charge and it is necessary to notify the electric vehicle to automatically open its charging port cover. Correspondingly, optionally, the charging trigger signal in the embodiments of the present application includes an operation signal when the charging switch on the charging pile device is operated or a gun removal signal when the charging gun is removed.

[0064] In the embodiments of the present application, when the charging pile device is broadcasting the second broadcast message, it detects whether it receives a charging trigger signal. The second broadcast message is used for the electric vehicle to perform signal detection. The second broadcast message can be regarded as an ordinary service broadcast to distinguish it from the first broadcast message, which is also beneficial for the electric vehicle to quickly distinguish. For the corresponding electric vehicle, detecting the second broadcast message can make it understand that: currently, there is a charging pile device in an idle state (not charging any electric vehicle and not in a fault state), it is determined that it has arrived near the charging pile device (or near the charging pile devices in the charging station yard), and it can receive the broadcast message of the charging pile device.

[0065] Optionally, when the charging pile device detects the charging trigger signal, it records the corresponding moment as the first moment S1, immediately stops broadcasting the second broadcast message to prevent the second broadcast message from being detected by other electric vehicles, and executes step 202. When not detecting the charging trigger signal, it keeps broadcasting the second broadcast message.

[0066] Optionally, in some embodiments, the second broadcast information includes the identity identifier (ID) of the charging pile device.

[0067] 202. The charging pile device stops broadcasting the second broadcast information and generates the first broadcast information, where the first broadcast information includes a first indication and a second indication. The first indication is used to indicate that the first broadcast information is a specific broadcast, and the second indication is an instruction for instructing the electric vehicle to open the charging port cover.

[0068] Among them, when the charging pile device detects a charging trigger signal, it indicates that a user needs to charge with this charging pile device, and stops broadcasting the second broadcast information to avoid being detected by other electric vehicles again, thinking that this charging pile device is in an idle state, thereby reducing the probability of incorrect judgment by the electric vehicle.

[0069] In some alternative embodiments, the charging pile device generating the first broadcast information may include:

[0070] Filling the first indication and the second indication into corresponding positions of a preset data format to generate the first broadcast information.

[0071] In the above embodiments, the first indication and the second indication are preset and stored in the charging pile device, and a preset data format is also stored. The preset data format may be a data format set by the manufacturer of the charging pile device before leaving the factory for storing manufacturer data. The first indication, the second indication, and the preset data format are all included in the communication standard protocol content and written into the communication protocol before the charging pile device and the electric vehicle leave the factory, so that the charging pile device and the electric vehicle can synchronize information and have a unified understanding of the first indication, the second indication, and the preset data format.

[0072] Exemplarily, the first indication can be filled into the starting position of the preset data format as the data header of the preset data format, so that the electric vehicle can quickly identify the first indication based on the data header to confirm that the first broadcast information is detected. The second indication can be filled into a custom data segment in the preset data format. Therefore, in this embodiment, generating the first broadcast information through a standardized data format is beneficial to the management of the broadcast information by the charging pile device and also beneficial to the electric vehicle to identify the broadcast information more quickly.

[0073] Further optionally, before the charging pile device fills the first indication and the second indication into corresponding positions of the preset data format to generate the first broadcast information, the method further includes:

[0074] Encrypting the second indication and auxiliary information according to a preset encryption key to obtain a second piece of information, where the auxiliary information includes a timestamp or a random number generated by a preset random algorithm.

[0075] Furthermore, the charging pile device fills the first indication and the second indication into corresponding positions of a preset data format to generate a first broadcast message, including:

[0076] Fill the first indication and the second information into corresponding positions of a preset data format to generate a first broadcast message.

[0077] In the above embodiment, a preset encryption key is also stored in the charging pile device, and a preset decryption key is stored in the electric vehicle. The preset encryption key and the preset decryption key are paired. The preset encryption key, the first indication, the second indication, and the preset data format are used as the standard communication protocol content of the charging pile device and are written into the communication protocol of the charging pile device before leaving the factory. Similarly, the preset decryption key, the first indication, the second indication, and the preset data format are used as the standard communication protocol content of the electric vehicle and are written into the communication protocol of the electric vehicle before leaving the factory.

[0078] In the above embodiment, the first indication is not encrypted, while the second indication for clearly instructing the electric vehicle to open the charging port cover is encrypted to improve the security of broadcast communication and prevent the first broadcast message from being attacked. Further, when encrypting the second indication, a timestamp or a random number generated by a random algorithm can also be added to prevent being simulated and encrypted by others, further improving the security.

[0079] It can be seen that the first broadcast message is broadcast in a way of plaintext identification + ciphertext instruction. Among them, the plaintext is the first indication, and the ciphertext instruction is the second indication, so that the electric vehicle to be charged can quickly detect the first broadcast message through the plaintext, obtain the instruction to open the charging port cover through the ciphertext instruction, and then open the charging port cover.

[0080] Exemplarily, for example, the data format and content of the first broadcast message are as follows:

[0081]

[0082]

[0083] In the content of the above first broadcast message, 0x06 is the start of the data and is the first indication, and 0xFF is the encrypted second indication. Among them, in the above embodiment, the ID of the charging pile device is also added in front of the encrypted second indication.

[0084] 203. The charging pile device broadcasts the above first broadcast message.

[0085] 204. The charging pile device detects whether the stop condition for stopping broadcasting the first broadcast message is met. The stop condition is at least one of detecting that the charging gun of the charging pile device is connected to the electric vehicle, the charging gun is placed back on the charging pile device, and the second duration exceeds the second preset duration. The second duration is the duration from when the charging trigger signal is detected to the current time. Among them, when the stop condition is met, step 205 is executed; when the stop condition is not met, step 204 is continued to be executed.

[0086] 205. The charging pile device stops broadcasting the first broadcast message.

[0087] After going through the above steps 201 - 203, the first broadcast message starts to be broadcast. In step 204, the charging pile device will enter the detection of the stop condition of the first broadcast message. When the stop condition is met, the first broadcast message is stopped from being broadcast.

[0088] Among them, the above stop condition can be detecting that the charging gun of the charging pile device is connected to the electric vehicle. That is to say, the user has plugged the charging gun into the electric vehicle for charging and entered the charging process. It is necessary to stop broadcasting the first broadcast message to avoid mis-opening the lid after other vehicles in the queue or passing vehicles detect the first broadcast message.

[0089] Or, the above stop condition can also be that the charging gun is placed back on the charging pile device. That is, perhaps the user did not charge the vehicle after removing the gun and then put the charging gun back on the charging pile device. At this time, it is also necessary to stop broadcasting the first broadcast message to release the charging pile device and improve resource utilization.

[0090] Or, the above stop condition can also be that the second duration exceeds the second preset duration. The second duration is the duration from when the charging trigger signal is detected to the current time. Among them, in the above introduction, the moment when the charging trigger signal is detected is recorded as the first moment S1, and the second duration is the duration from the first moment S1 to the current time. In this way, by restricting the broadcast duration of the first broadcast message, the waste of resources caused by the charging pile device being occupied but not really used for charging the vehicle is avoided.

[0091] After executing step 205, the charging pile device broadcasts the second broadcast message.

[0092] Among them, after the charging pile device stops broadcasting the first broadcast message, the charging pile device is released and re - enters the idle state, and starts to broadcast the second broadcast message again, so that other electric vehicles can detect the charging pile device based on the second broadcast message and realize the charging of another process.

[0093] Therefore, by implementing the above embodiments, when the charging pile device broadcasts the second broadcast information, it detects whether a charging trigger signal is received. When the charging trigger signal is detected, it stops broadcasting the second broadcast information, indicating that the charging pile device is in use. Then, it generates the first broadcast information and broadcasts it. After broadcasting the first broadcast information, it will continuously judge the stop broadcast condition in real time to stop playing the first broadcast information when the stop playing condition is met, thereby releasing the charging pile device and then starting to play the first broadcast information again to provide it for other electric vehicles to use, avoiding the occupation of the charging pile device resources.

[0094] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of the vehicle charging port cover control method disclosed in Embodiment 3 of the present application; Figure 3 Applied to an electric vehicle, the vehicle charging port cover control method may include:

[0095] 301. The electric vehicle detects whether it receives the first broadcast information. The first broadcast information at least includes a first indication and a second indication. The first indication is used to indicate that the first broadcast information is a specific broadcast, and the second indication is an instruction for indicating the electric vehicle to open the charging port cover. Among them, when the first broadcast information is detected, step 302 is executed. When the first broadcast information is not detected, this process ends.

[0096] In the embodiment of the present application, when the electric vehicle is parked and in the parking gear state, and the charging port cover is in the closed state and not in the sleep state, it detects whether it receives the first broadcast information.

[0097] Among them, a wireless communication module is set in the electric vehicle, which can scan and detect the broadcast information of the charging pile device. For example, the electric vehicle can be provided with a Bluetooth module, or modules such as WiFi, ZigBee, radio frequency, USB, etc., so as to realize communication corresponding to wireless networks such as Bluetooth, WiFi, ZigBee, radio frequency, or USB. Taking Bluetooth as an example, in the embodiment of the present application, the electric vehicle acts as the host mode and actively scans the Bluetooth signal of the charging pile device to detect the first broadcast information.

[0098] 302. The electric vehicle judges whether the current opening condition of the charging port cover is met. When the opening condition is met, step 303 is executed. When the opening condition is not met, this process ends.

[0099] Optionally, the above opening conditions at least include: the electric vehicle has a function to support automatically opening the charging port cover, the electric vehicle is parked and in the parking gear state, the charging port cover is in the closed state, and the charging gun unmounting and opening function of the electric vehicle is in the on state.

[0100] In step 302, after receiving the first broadcast message, the electric vehicle further determines whether it meets the opening condition of the charging port cover based on the included second indication. When the opening condition of the charging port cover is met, it is determined that the vehicle itself needs to be charged and can be charged.

[0101] 303. The electric vehicle opens the charging port cover.

[0102] For the electric vehicle, after detecting and receiving the first broadcast message, according to the first indication and the second indication, it is determined that the charging pile device instructs to open the charging port cover. Further detecting that if the electric vehicle currently meets the opening condition of the charging port cover, then the charging port cover of the electric vehicle is opened; by implementing the embodiments of the present application, the whole process does not require the electric vehicle to be bound to the charging pile device. The electric vehicle will automatically open the charging port cover according to the first indication, the second indication included in the first broadcast message, and the opening condition it meets. Moreover, the first indication, the second indication included in the first broadcast message, and the setting of the opening condition are all convergence conditions, which can help the electric vehicle accurately locate whether it is for its own charging, and at the same time can reduce the probability of mis-opening the cover by passing vehicles or queuing vehicles. It is not only suitable for the application environment of home charging piles, but also suitable for application environments such as public operation charging stations, effectively reducing the probability of mis-opening the cover and improving the accuracy of opening the charging port cover.

[0103] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of the vehicle charging port cover control method disclosed in the fourth embodiment of the present application; Figure 4 Applied to an electric vehicle, the vehicle charging port cover control method may include:

[0104] 401. The electric vehicle extracts the first information and the second information from the corresponding positions of the detected broadcast message according to a preset data format.

[0105] 402. The electric vehicle determines whether the first information is the first indication and whether the second information includes the second indication; when it is determined that the first information is the first indication and the second information includes the second indication, step 403 is executed. On the contrary, when the first information is not the first indication and / or the second information does not include the second indication, the broadcast message is discarded and this process ends.

[0106] 403. The electric vehicle determines that the first broadcast message is detected.

[0107] In steps 401 to 403, the first indication, the second indication, and the preset data format, as the content of the communication standard protocol, can be written into their respective communication protocols before the electric vehicle and the charging pile device leave the factory, or synchronized later through the update of the communication protocol software, so that the charging pile device and the electric vehicle can synchronize information and have a unified understanding of the first indication, the second indication, and the preset data format.

[0108] Exemplarily, the first indication can be filled at the beginning position of a preset data format as the data header of the preset data format, so that the electric vehicle can quickly identify the first indication according to the data header to confirm that the first broadcast information is detected. Furthermore, in the above embodiments, the electric vehicle can extract the first information from the data header position of the preset data format according to the preset data format, and then determine whether the first information is the first indication. Limiting the position is beneficial for the electric vehicle to more quickly identify whether it is the first broadcast information.

[0109] Exemplarily, the second indication can be filled into the custom data segment of the preset data format, such as 0xFF shown above.

[0110] Optionally, before the electric vehicle determines whether the second information contains the second indication, it further includes:

[0111] Decrypt the second information according to a preset decryption key;

[0112] Furthermore, determining whether the second information contains the second indication includes:

[0113] Determine whether the decrypted second information contains the second indication and auxiliary information.

[0114] In this application, a preset encryption key is stored in the charging pile device, and a preset decryption key is stored in the electric vehicle. The preset encryption key and the preset decryption key are paired. The preset encryption key, the first indication, the second indication, and the preset data format are used as the standard communication protocol content of the charging pile device and are written into the communication protocol of the charging pile device before leaving the factory. Similarly, the preset decryption key, the first indication, the second indication, and the preset data format are used as the standard communication protocol content of the electric vehicle and are written into the communication protocol of the electric vehicle before leaving the factory.

[0115] Among them, the first indication is not encrypted, while the second indication for clearly instructing the electric vehicle to open the charging port cover is encrypted to improve the security of broadcast communication and prevent the first broadcast information from being attacked. Further, when encrypting the second indication, a timestamp or a random number generated by a random algorithm can also be added to prevent being simulated and encrypted by others, further improving the security.

[0116] It can be seen that the first broadcast information is broadcast in a way of using plaintext recognition + ciphertext instruction. Among them, the plaintext is the first indication, and the ciphertext instruction is the second indication, so that the electric vehicle that needs to be charged can detect the first broadcast information through the plaintext and know that it needs to open the charging port cover through the ciphertext instruction.

[0117] 404. The electric vehicle determines whether the current conditions for opening the charging port cover are met; when the opening conditions are met, step 405 is executed, and when the opening conditions are not met, this process ends.

[0118] 405. The electric vehicle opens the charging port cover.

[0119] In the embodiment of the present application, the electric vehicle can determine whether the corresponding positions in the data format corresponding to the first broadcast information are the first indication and the second indication through scanning detection. After determining that the first indication and the second indication are included, it is determined that the first broadcast information is detected. Then, when it is determined that the opening conditions are met, the automatic opening of the charging port cover is realized, and the first indication and the second indication included in the first broadcast information, as well as the setting of the opening conditions, are all convergence conditions, which can not only enable the electric vehicle to accurately locate itself, but also avoid mis-opening of the charging port cover by passing vehicles or queuing vehicles, improving the accuracy of opening the charging port cover.

[0120] Please refer to Figure 5 , Figure 5 which is a schematic flowchart of the vehicle charging port cover control method disclosed in Embodiment 5 of the present application; Figure 5 Applied to an electric vehicle, the vehicle charging port cover control method may include:

[0121] 501. The electric vehicle detects the second broadcast information, which is used to provide wireless signal detection for the electric vehicle.

[0122] Optionally, in the embodiment of the present application, if the electric vehicle meets the initial charging conditions, it starts to detect the second broadcast information. The initial charging conditions at least include that the electric vehicle is in a parked state and in the parking gear state, its charging port cover is in a closed state and not in a dormant state. By judging the initial charging conditions, it can ensure a safe charging environment for the electric vehicle and improve the use safety of the electric vehicle.

[0123] It should be noted that when it is detected that the electric vehicle is parked, this moment is recorded as the second moment S2 and the timing starts.

[0124] Optionally, the second broadcast information also includes the ID of the charging pile device.

[0125] 502. After detecting the second broadcast information, the electric vehicle stops detecting the second broadcast information and detects whether it receives the first broadcast information. Among them, when the first broadcast information is detected, step 503 is executed, and when the first broadcast information is not detected, this process ends.

[0126] Optionally, during the process of the electric vehicle detecting whether it receives the first broadcast information, it also includes:

[0127] Detect whether the stop detection condition is satisfied. The stop detection condition is determined to have detected the first broadcast message, the charging port cover of the electric vehicle is being opened or is already in the open state, the electric vehicle does not have the function to support automatically opening the charging port cover, the electric vehicle is not in the parked state or not in the parking gear state, the charging gun removal and cover opening function of the electric vehicle is in the closed state, and at least one of the first duration exceeding the first preset duration. The first duration is the parking duration of the electric vehicle from the start of parking to the current moment; after the stop detection condition is satisfied, stop detecting the first broadcast message.

[0128] In the above embodiment, the parking duration is the duration corresponding to the start time of the second moment S2 to the current moment. When detecting the first broadcast message, if the situation corresponding to the above stop detection condition is detected, it means that the electric vehicle is not suitable for charging at present, and the detection of the first broadcast message will be stopped immediately to avoid charging accidents and improve charging safety.

[0129] Optionally, in some embodiments, the first broadcast message includes the identity identifier (ID) of the charging pile device. As introduced above, the ID of the charging pile device can be encrypted by placing it in front of the second indication. The second broadcast message also includes the ID of the charging pile device. In the embodiments of the present application, after the electric vehicle first detects the second broadcast message, it determines that it has reached near the charging pile device, then stops detecting the second broadcast message, and then detects the first broadcast message. Therefore, when the electric vehicle detects the second broadcast message, it can read the ID of the charging pile device from the second broadcast message, and then when it detects the first broadcast message, read the ID of the charging pile device from the first broadcast message, and determine whether the ID in the first broadcast message is the same as the ID in the second broadcast message. If they are the same, it is considered that the first broadcast message and the second broadcast message are sent by the same charging pile device, and step 503 is executed. If they are not the same, the first broadcast message is discarded, and then detection is restarted.

[0130] It should be noted that when detecting the second broadcast message, multiple second broadcast messages may be detected. The ID of the charging pile device will be read from each second broadcast message, and then the ID of the charging pile device read from the second broadcast message will be compared with the ID in the first broadcast message respectively. If one of them is the same as the ID in the first broadcast message, step 503 is executed. If they are all different, the first broadcast message is discarded, and then detection is restarted.

[0131] By the above judgment of the ID of the charging pile device, the charging pile device can be converged to help the electric vehicle accurately locate the charging pile device. Then, combined with the electric vehicle according to the first indication, the second indication and the opening condition, the accurate matching of the electric vehicle and the charging pile device is virtually realized, which is beneficial to improving the accuracy rate of the charging port cover.

[0132] 503. The electric vehicle determines whether the current conditions for opening the charging port cover are met; when the opening conditions are met, step 504 is executed, and when the opening conditions are not met, this process ends.

[0133] 504. The electric vehicle opens the charging port cover.

[0134] Among them, for an electric vehicle, it can be that the in-vehicle TBOX controller in the electric vehicle detects the first broadcast information and the second broadcast information through the communication module. Correspondingly, optionally, step 504 may include: the in-vehicle TBOX controller sends a charging request to the vehicle control unit (VCU) or the battery management system (BMS), and then the vehicle control unit (VCU) or the battery management system (BMS) opens the charging port cover based on the charging request.

[0135] By implementing the embodiments of the present application, the entire process does not require the electric vehicle to be bound to the charging pile device. The electric vehicle will automatically open the charging port cover according to the broadcast signal and the opening conditions, and both the first indication and the second indication included in the first broadcast information, as well as the setting of the opening conditions, are convergence conditions to determine whether it is necessary to open the charging port cover by itself, avoiding mis-opening of the cover, and also being able to avoid mis-opening of the cover by passing vehicles or queuing vehicles, improving the accuracy of opening the charging port cover; further, it can also improve charging safety.
