Description

Technical Field

[0001] This disclosure relates to the field of charging technology, and in particular to a charging control method, device, vehicle, charging pile, and charging system. Background Technology

[0002] Increasing the charging current is a crucial way to shorten the charging time of electric vehicles. However, current widely deployed charging communication protocols strictly limit the upper limit of the charging current to ensure safety, which creates a bottleneck in the approach of increasing the charging current.

[0003] Although the new generation of national standards has significantly expanded the range of current parameters, paving the way for ultra-high-speed charging, its industrial implementation faces real challenges: the massive existing number of electric vehicles and charging piles need to be upgraded, a process that will take a long time. Therefore, how to develop a compatible "supercharging" extension mechanism to overcome inherent current limitations without changing the existing protocol framework and parameter definitions has become an urgent problem to be solved. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this disclosure provides a charging control method, device, vehicle, charging pile, and charging system.

[0005] According to a first aspect of the present disclosure, a charging control method is provided, applied to a vehicle, comprising:

[0006] Upon receiving a first message from a charging pile, if the first verification information in the first message passes verification, a second message is sent to the charging pile. The second message includes second verification information, a vehicle identification number, and a current offset.

[0007] Perform a charging handshake process with the charging pile;

[0008] Once the charging handshake process is complete, the current offset in the second message is used to adjust the charging current value requested by the vehicle.

[0009] In the above technical solution, a "supercharging" extension mechanism compatible with existing protocols is constructed by adding the interaction of a first message and a second message before the charging handshake. Before the charging handshake process is completed, the vehicle sends a second message including a current offset to the charging pile, allowing the charging pile to know the current adjustment requirement in advance and adjust its output current accordingly. The vehicle also uses this current offset to adjust the charging current value requested by the vehicle. In this way, while ensuring that the current offsets at both ends are matched, the hardware potential of the vehicle and the charging pile can be fully utilized. By using the current offset to overcome the inherent current limit, the charging current value can be increased, the charging time of electric vehicles can be shortened, and charging safety can be ensured at the same time, while meeting the user's fast charging needs. By setting the first verification information in the first message and sending the second message after successful verification, incorrect charging pile access can be prevented, ensuring charging safety. The second verification information in the second message can also play a role in preventing tampering and counterfeiting.

[0010] In some possible implementations, the first verification information includes the Supercharging Protocol version of the charging pile; the step of sending a second message to the charging pile if the first verification information in the first message passes verification includes:

[0011] If the supercharging protocol version of the charging pile matches the supercharging protocol version of the vehicle, then the first verification information is determined to be verified, and the second message is sent to the charging pile.

[0012] In the above technical solution, verifying the supercharging protocol version on the vehicle side can avoid charging failures caused by incompatibility of the supercharging protocol version, and reduce the probability of problems occurring in charging piles and vehicles during the charging process.

[0013] In some possible implementations, the first message may also include a random number.

[0014] In the above technical solution, random numbers can serve as a means of preventing plagiarism.

[0015] In some possible implementations, the first message may also include at least one of the charging pile manufacturer information and the charging pile model.

[0016] In the above technical solution, the charging pile manufacturer information and charging pile model in the first message enable the vehicle to accurately identify the charging pile information and confirm the whitelist.

[0017] In some possible implementations, the second message may also include at least one of vehicle manufacturer information, vehicle model, and vehicle function settings.

[0018] In the aforementioned technical solution, vehicle manufacturer information and vehicle model enable charging piles to accurately identify vehicle information for whitelist confirmation. The second message includes vehicle function settings, allowing for efficient communication between vehicle manufacturers and charging pile manufacturers, precisely adapting to needs and improving the charging service experience and collaborative efficiency.

[0019] In some possible implementations, the method further includes:

[0020] The fields in the second message are rearranged in an out-of-order manner.

[0021] In the above technical solution, the confidentiality of the second message can be enhanced by reordering the message, reducing the risk of the message being stolen and tampered with, increasing the difficulty of cracking, and providing more reliable security for communication.

[0022] In some possible implementations, the method further includes:

[0023] The transmission of the second message shall cease when at least one of the following conditions is met:

[0024] Receives a charger handshake message from the charging pile during the charging handshake process;

[0025] Receives a charger identification message from the charging pile during the charging handshake process;

[0026] The duration of sending the second message has reached the first preset duration.

[0027] The above technical solution not only ensures the orderly progress of the charging handshake process, but also optimizes the utilization of communication resources and improves the stability of the collaborative work between the vehicle and the charging pile.

[0028] In some possible implementations, the method further includes:

[0029] If the first preset field in the received charger identification message is consistent with the current offset in the second message, then the current offset in the second message is filled into the second preset field in the BMS identification message, and the charger identification message is sent by the charging pile.

[0030] The BMS identification message is sent to the charging pile.

[0031] In the above technical solution, the vehicle can confirm that the charging station agrees to perform charging according to the current offset in the second message. This avoids situations where the vehicle or charging station does not perform charging according to the offset agreed in the second message, but the other party is unaware and still performs charging according to the agreed offset, thereby achieving the purpose of ensuring charging safety and improving charging efficiency.

[0032] In some possible implementations, the method further includes:

[0033] If a maximum output capacity message of the charger is received from the charging pile, the maximum output capacity message of the charger is parsed according to the current offset on the vehicle side.

[0034] If the analysis result indicates that the direction of the current obtained from the analysis is incorrect, or exceeds the preset maximum current value, then the charging process will end.

[0035] In the above technical solution, by adding current offset verification and charging current maximum limit, abnormal charging can be detected and terminated in a timely manner, ensuring charging safety, preventing equipment damage, and improving charging reliability.

[0036] According to a second aspect of the present disclosure, a charging control method is provided, applied to a charging pile, comprising:

[0037] Once a physical connection is established between the vehicle and the charging station, a first message is sent to the vehicle, the first message including first verification information;

[0038] If the second verification information in the second message passes the verification upon receiving the second message, a charging handshake process is performed with the vehicle. The second message also includes a vehicle identification code and a current offset.

[0039] Once the charging handshake process is complete, the charging current value output by the charging pile is adjusted using the current offset in the second message.

[0040] In the above technical solution, a "supercharging" extension mechanism compatible with existing protocols is constructed by adding the interaction of a first message and a second message before the charging handshake. Before the charging handshake process is completed, by receiving the current offset in the second message sent by the vehicle, the charging pile can understand the vehicle's charging current adjustment needs in advance before the charging handshake process is completed, and set the output current more accurately. The vehicle will also use this current offset to adjust the charging current value requested by the vehicle. In this way, while ensuring that the current offsets at both ends are matched, the hardware potential of the vehicle and the charging pile can be fully utilized. By using the current offset to break through the inherent current limit, the charging current value can be increased, the charging time of electric vehicles can be shortened, and charging safety can be ensured at the same time to meet the user's fast charging needs. The first verification information in the first message can effectively prevent incorrect charging pile access, ensuring charging safety from the source. The second verification information in the second message has anti-tampering and anti-counterfeiting functions.

[0041] In some possible implementations, the second verification information includes at least one of the following: the vehicle's supercharging protocol version, field information processed by a preset algorithm, and a random number in the first message;

[0042] If the second verification information in the second message passes verification, then a charging handshake process is performed with the vehicle, including:

[0043] If the second verification information matches the corresponding information in the charging pile, then the second verification information is determined to have passed verification, and a charging handshake process is executed with the vehicle.

[0044] In the above technical solution, the use of second verification information for verification can effectively prevent tampering and counterfeiting, ensure charging safety, ensure the smooth start of the charging handshake process, and improve charging reliability.

[0045] In some possible implementations, the preset algorithm is synchronized in the charging station and the vehicle.

[0046] The above technical solution can ensure the successful verification of the second verification information.

[0047] In some possible implementations, the second message may also include at least one of vehicle manufacturer information, vehicle model, and vehicle function settings.

[0048] In the aforementioned technical solution, vehicle manufacturer information and vehicle model enable charging piles to accurately identify vehicle information for whitelist confirmation. The second message includes vehicle function settings, allowing for efficient communication between vehicle manufacturers and charging pile manufacturers, precisely adapting to needs and improving the charging service experience and collaborative efficiency.

[0049] In some possible implementations, the first message may also include at least one of the charging pile manufacturer information and the charging pile model.

[0050] In the above technical solution, the charging pile manufacturer information and charging pile model in the first message enable the vehicle to accurately identify the charging pile information and confirm the whitelist.

[0051] In some possible implementations, the method further includes:

[0052] The fields in the first message are combined in an out-of-order manner.

[0053] In the above technical solution, by combining messages in an out-of-order manner, the confidentiality of the first message can be enhanced, the risk of the message being stolen and tampered with can be reduced, the difficulty of cracking can be increased, and more reliable security can be provided for communication.

[0054] In some possible implementations, the method further includes:

[0055] The transmission of the first message shall be stopped if at least one of the following conditions is met:

[0056] The second message was received;

[0057] The duration of sending the first message has reached the second preset duration.

[0058] The above technical solution can precisely control the message interaction process, avoid invalid or redundant communication, ensure the accuracy and timeliness of the charging handshake process, guarantee the stability and safety of the charging process, and optimize the charging experience.

[0059] In some possible implementations, sending a first message to the vehicle after a physical connection has been established between the vehicle and the charging station includes:

[0060] Once a physical connection is established between the vehicle and the charging station, and the user is detected performing a scanning operation after the connection duration has reached a third preset duration, the first message is sent to the vehicle.

[0061] The above technical solution can avoid the failure of the supercharging function due to forgotten message exchanges caused by vehicle hibernation, thereby ensuring the normal operation of the supercharging function.

[0062] In some possible implementations, the method further includes:

[0063] The current offset from the second message is filled into the first preset field of the charger identification message; the charger identification message is then sent to the vehicle.

[0064] In the above technical solution, the vehicle can be informed that the charging station agrees to charge according to the current offset in the second message.

[0065] In some possible implementations, the method further includes:

[0066] If the second preset field in the BMS identification message received from the vehicle is consistent with the current offset in the second message, it is determined that the vehicle and the charging pile will perform charging according to the current offset in the second message.

[0067] The above technical solution can prevent situations where the vehicle or charging pile does not perform charging according to the offset agreed in the second message, but the other party is unaware of this and still performs charging according to the agreed offset, thereby achieving the purpose of ensuring charging safety and improving charging efficiency.

[0068] In some possible implementations, the method further includes:

[0069] If a battery charging parameter message is received from the vehicle, the battery charging parameter message is parsed according to the current offset on the charging pile side.

[0070] If the analysis result indicates that the direction of the current obtained from the analysis is incorrect, or exceeds the preset maximum current value, then the charging process will end.

[0071] In the above technical solution, by adding current offset verification and charging current maximum limit, abnormal charging can be detected and terminated in a timely manner, ensuring charging safety, preventing equipment damage, and improving charging reliability.

[0072] According to a third aspect of the present disclosure, a charging control device is provided, applied to a vehicle, comprising:

[0073] The first sending module is configured to, upon receiving a first message from the charging pile, send a second message to the charging pile if the first verification information in the first message passes verification. The second message includes second verification information, a vehicle identification code, and a current offset.

[0074] The first handshake module is used to perform a charging handshake process with the charging pile;

[0075] The first control module is used to adjust the charging current value requested by the vehicle by utilizing the current offset in the second message after the charging handshake process is completed.

[0076] According to a fourth aspect of the present disclosure, a charging control device is provided, applied to a charging pile, comprising:

[0077] The second sending module is used to send a first message to the vehicle when a physical connection is established between the vehicle and the charging pile. The first message includes first verification information.

[0078] The second handshake module is used to perform a charging handshake process with the vehicle if the second verification information in the second message passes the verification upon receiving the second message. The second message also includes a vehicle identification code and a current offset.

[0079] The second control module is used to adjust the charging current value output by the charging pile by utilizing the current offset in the second message after the charging handshake process is completed.

[0104] Figure 11 This is a block diagram illustrating a charging station according to an exemplary embodiment. Detailed Implementation

[0105] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0106] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0107] Figure 1 This is a flowchart illustrating a charging control method according to an exemplary embodiment. This method can be applied to vehicles. Figure 1 As shown, the method may include steps S101 to S103.

[0108] In step S101, if the first verification information in the first message is successfully verified upon receiving the first message from the charging pile, then a second message is sent to the charging pile.

[0109] The second message includes second verification information, vehicle identification number, and current offset.

[0110] The first and second messages can be private messages. The first message, CMP (Charger Private message), is a private message sent from the charging pile to the vehicle; the second message, VPM (Vehicle Private message), is a private message sent from the vehicle to the charging pile. These two messages can be defined as Supercharging Protocol handshake messages. The IDs of the first and second messages are staggered from those of existing charging communication protocols to avoid confusion. Furthermore, the IDs of the first and second messages are also staggered from other existing private messages to further prevent confusion and improve the compatibility of the Supercharging Protocol.

[0111] In one embodiment, the validity of the first verification information can be determined by comparing the consistency of the information.

[0112] In step S102, a charging handshake process is performed with the charging pile.

[0113] The message exchange process between the vehicle and the charging station to perform the charging handshake can be as follows: Figure 2 As shown in the dashed box. The charging pile sends a charger handshake message (CHM) to the vehicle; after receiving the CHM, the vehicle sends a vehicle handshake message (BHM) back to the charging pile; after receiving the BHM, the charging pile performs an insulation test and sends a charger identification message (CRM) to the vehicle after the insulation test is completed. At this time, the first byte of the CRM message data is 0x00; the vehicle's BMS (Battery Management System) receives the CRM and sends back a BMS identification message (BRM); the charging pile parses the BRM to return a CRM with the first byte being 0xAA. If the vehicle receives a CRM with the first byte being 0xAA, it can determine that the charging handshake was successful and then enters the parameter configuration stage.

[0114] In step S103, after the charging handshake process is completed, the charging current value requested by the vehicle is adjusted using the current offset in the second message.

[0115] In one embodiment, once the charging handshake process is determined to be complete, the vehicle can use the current offset in the second message to configure parameters to adjust the charging current value requested by the vehicle during the charging process, thereby enabling subsequent charging.

[0116] In the above technical solution, a "supercharging" extension mechanism compatible with existing protocols is constructed by adding the interaction of a first message and a second message before the charging handshake. Before the charging handshake process is completed, the vehicle sends a second message including a current offset to the charging pile, allowing the charging pile to know the current adjustment requirement in advance and adjust its output current accordingly. The vehicle also uses this current offset to adjust the charging current value requested by the vehicle. In this way, while ensuring that the current offsets at both ends are matched, the hardware potential of the vehicle and the charging pile can be fully utilized. By using the current offset to overcome the inherent current limit, the charging current value can be increased, the charging time of electric vehicles can be shortened, and charging safety can be ensured at the same time, while meeting the user's fast charging needs. By setting the first verification information in the first message and sending the second message after successful verification, incorrect charging pile access can be prevented, ensuring charging safety. The second verification information in the second message can also play a role in preventing tampering and counterfeiting.

[0117] Figure 3 This is a flowchart illustrating a charging control method according to an exemplary embodiment. This method can be applied to charging piles. Figure 3 As shown, the method may include steps S301 to S303.

[0118] In step S301, after the vehicle has established a physical connection with the charging pile, a first message is sent to the vehicle.

[0119] The first message includes the first verification information. Establishing a physical connection between the vehicle and the charging station refers to the establishment of a physical connection between the charging station's charging port and the vehicle's charging socket.

[0120] In an optional embodiment, once a physical connection is established between the charging station's charging port and the vehicle's charging socket, the charging station can immediately send a first message to the vehicle. Thus, after plugging in the charging port, the vehicle can directly start the charging process without scanning a code, saving user steps and effectively improving the user experience.

[0121] In another optional embodiment, after the vehicle establishes a physical connection with the charging pile and the user performs a scanning operation after the connection time reaches a third preset time, a first message is sent to the vehicle.

[0122] For example, the third preset duration can be pre-set based on actual needs, such as 2 minutes. Some vehicles have not enabled the plug-and-charge function, and the following situation may occur during use: After establishing a physical connection with the charging station, the vehicle enters a sleep state because it has not scanned the code to start. If the first and second messages are exchanged directly at this time, the vehicle may forget that it has already completed the first and second message exchanges with the charging station after entering sleep mode, thus causing the supercharging function to fail. However, after the vehicle establishes a physical connection with the charging station and the connection time reaches the third preset duration, the first message is only sent to the vehicle when the user scans the code. This avoids the supercharging function failing due to the vehicle forgetting the message exchanges during sleep mode, thus ensuring the normal operation of the supercharging function.

[0123] The CC1 terminal of the vehicle and the charging station is shorter than the CC2 terminal. When plugging in the charging gun, CC2 is connected first, followed by CC1. The CC1 terminal is used by the charging station to detect whether the charging gun is connected correctly, while CC2 is used by the vehicle. If the charging station detects a successful connection, it also ensures that the vehicle is connected correctly; conversely, if the vehicle detects a successful connection, it does not necessarily mean that the charging station is connected correctly. Therefore, the first message is sent after the charging station detects a successful connection.

[0124] In step S302, if the second verification information in the second message passes verification upon receiving the second message, a charging handshake process is performed with the vehicle.

[0125] The second message also includes the vehicle identification number and current offset.

[0126] In one embodiment, the validity of the second verification information can be determined by comparing the consistency of the information. The charging handshake process between the vehicle and the charging station is as follows: Figure 2 As shown, the specific process has been described in detail above, and will not be elaborated on here.

[0127] In step S303, after the charging handshake process is completed, the charging current value output by the charging pile is adjusted using the current offset in the second message.

[0128] In one embodiment, upon determining that the charging handshake process is complete, the charging pile can use the current offset in the second message to configure parameters to adjust the charging current value output by the charging pile during the charging process, thereby enabling subsequent charging.

[0129] In the above technical solution, a "supercharging" extension mechanism compatible with existing protocols is constructed by adding the interaction of a first message and a second message before the charging handshake. Before the charging handshake process is completed, by receiving the current offset in the second message sent by the vehicle, the charging pile can understand the vehicle's charging current adjustment needs in advance before the charging handshake process is completed, and set the output current more accurately. The vehicle will also use this current offset to adjust the charging current value requested by the vehicle. In this way, while ensuring that the current offsets at both ends are matched, the hardware potential of the vehicle and the charging pile can be fully utilized. By using the current offset to break through the inherent current limit, the charging current value can be increased, the charging time of electric vehicles can be shortened, and charging safety can be ensured at the same time to meet the user's fast charging needs. The first verification information in the first message can effectively prevent incorrect charging pile access, ensuring charging safety from the source. The second verification information in the second message has anti-tampering and anti-counterfeiting functions.

[0130] Figure 4 The diagram illustrates the signaling interaction between a vehicle and a charging station when implementing the charging control method provided in this disclosure, according to one embodiment. Figure 4 The steps shown are in conjunction with the above text. Figure 1 and Figure 3 The description is consistent with the actual situation, so I will not repeat it here.

[0131] As mentioned above, the first message includes first verification information, which is used by the vehicle to verify the charging pile to prevent incorrect charging pile access and ensure charging safety.

[0132] In an optional embodiment, the first verification information includes the supercharging protocol version of the charging station; the vehicle can verify the first verification information in the following ways:

[0133] If the supercharging protocol version of the charging pile matches the supercharging protocol version of the vehicle, then the first verification information is confirmed to have passed verification.

[0134] For example, after receiving the first message from the charging pile, the vehicle can parse the message to extract the supercharging protocol version of the charging pile. Simultaneously, the vehicle can read pre-configured supercharging protocol versions it currently supports, such as "V2.0, V2.5, V3.0," from its own storage unit. Then, the vehicle compares the charging pile's supercharging protocol version with its own supported versions one by one. If both the charging pile's and the vehicle's supercharging protocol versions are V2.0, the first verification message is considered valid. Matching supercharging protocol versions means that both parties have consistent security mechanisms, effectively preventing security vulnerabilities caused by protocol incompatibility and ensuring the safety and reliability of the charging process.

[0135] Therefore, verifying the supercharging protocol version on the vehicle side can avoid charging failures caused by incompatibility of supercharging protocol versions, and reduce the probability of problems occurring in charging piles and vehicles during the charging process.

[0136] Correspondingly, if the supercharging protocol version of the charging pile and the supercharging protocol version of the vehicle do not match, it is determined that the first verification information has failed the verification. In this case, the vehicle may not send a second message to the charging pile.

[0137] In an optional embodiment, the first message also includes a random number. This random number is randomly generated by the charging station and varies with each charging session and each plug-in, serving to prevent copying and ensure the safety of supercharging. When a third party parses the interaction messages between the vehicle and the charging station, the random number will influence the message and prevent it from being directly copied and used.

[0138] For example, if the supercharging protocol version of the charging pile matches the supercharging protocol version of the vehicle, the random number in the first message can be extracted and set in the second message.

[0139] In an optional embodiment, the first message also includes at least one of charging pile manufacturer information and charging pile model. The charging pile manufacturer information and charging pile model in the first message enable the vehicle to accurately identify the charging pile information and perform whitelist confirmation. This allows for functional expansion based on the cooperation between the vehicle manufacturer and the charging pile manufacturer (e.g., plug-and-charge), which is beneficial for the subsequent access of more charging pile manufacturers.

[0140] In an optional embodiment, the method provided in this disclosure may further include:

[0141] The charging pile reorders the fields in the first message.

[0142] For example, the first message might contain the following fields: the charging station's supercharging protocol version is ABC; the random number is DEF; the charging station manufacturer information is GHI; and the charging station model is JKL. These four fields can be shuffled and arranged alternately, resulting in a first message like ADFBHCGIKL. The receiving end can know the message reordering rules and combination methods in advance and pre-configure the corresponding parsing algorithm. When receiving such reordered messages, it can split and reassemble the messages according to the corresponding parsing algorithm to accurately restore the original information. Thus, by reordering the messages, the confidentiality of the first message can be enhanced, reducing the risk of message theft and tampering, increasing the difficulty of cracking, and providing more reliable security for communication.

[0143] In an optional embodiment, the method provided in this disclosure may further include:

[0144] The charging station will stop sending the first message if at least one of the following conditions is met:

[0145] The second message was received;

[0146] The time taken to send the first message has reached the second preset time.

[0147] For example, the second preset duration can be preset based on actual needs, such as 5 seconds. For instance, the second preset duration can be determined based on the time from when the user plugs in the charging gun to when they scan the code to start the charging process, thus avoiding interference with the user's charging process after plugging in the gun and scanning the code to start the charging. The vehicle sending the second message indirectly closes the Supercharging Protocol response between the vehicle and the charging station: the charging station receiving the second message indicates that the vehicle has successfully received the first message and that the first verification information in the first message has been verified. To ensure smooth interaction of subsequent messages, the charging station can stop sending the first message.

[0148] In this way, the message interaction process can be precisely controlled, invalid or redundant communication can be avoided, the accuracy and timeliness of the charging handshake process can be ensured, the stability and safety of the charging process can be guaranteed, and the charging experience can be optimized.

[0149] As previously mentioned, the second message includes second verification information, vehicle identification number, and current offset.

[0150] Vehicle identification numbers are used by charging stations to verify a vehicle's account information, such as charging fee deductions and discounts, and even functional restrictions.

[0151] The current offset is the desired current offset for the vehicle to achieve supercharging. The current offset determines the upper limit of the charging current. Taking the current offset of -400A in the currently widely deployed charging communication protocol as an example, the current offset in the second message can be less than -400A. Furthermore, the current offset in the second message can be determined based on the vehicle's charging upper limit; it can be defined as an offset of -2000A or higher.

[0152] The second verification information has anti-tampering and anti-counterfeiting functions.

[0153] In an optional embodiment, the second verification information includes at least one of the following: the vehicle's supercharging protocol version, field information processed by a preset algorithm, and a random number in the first message;

[0154] Charging stations can verify the second verification information in the following ways:

[0155] If the second verification information matches the corresponding information in the charging pile, then the second verification information is deemed to have passed verification, and a charging handshake process is executed with the vehicle.

[0156] Taking the vehicle's Supercharging Protocol version as an example, the charging pile can parse the second message sent by the vehicle after receiving it, and extract the vehicle's Supercharging Protocol version. At the same time, the charging pile can read the pre-configured Supercharging Protocol version supported by the current charging pile from its own storage unit. If the Supercharging Protocol version of the charging pile matches the Supercharging Protocol version of the vehicle, the charging pile can determine that the Supercharging Protocol version verification is successful.

[0157] Taking the example where the second verification information includes the random number in the first message. After receiving the second message sent by the vehicle, the charging pile can parse the second message and extract the random number; at the same time, the charging pile can read the random number in the first message sent from its own storage unit. If the random numbers in the first message and the second message are the same, it can be determined that the random number verification is successful.

[0158] Taking the second verification information, which includes field information processed by a preset algorithm, as an example, after receiving the second message sent by the vehicle, the charging pile can parse the message to extract information. The fields to be processed by the preset algorithm can be other content in the second message, such as at least one of the vehicle's supercharging protocol version, random number, current offset, vehicle manufacturer information, vehicle model, and vehicle function settings. This preset algorithm is synchronized in both the charging pile and the vehicle. Upon receiving the second message, the charging pile can use its built-in preset algorithm to process the content in the second message other than the field information processed by the preset algorithm, and compare the processing result with the field information in the second message that has been processed by the preset algorithm. If the comparison result is consistent, it can be determined that the field information processed by the preset algorithm has passed verification.

[0159] The second verification information covers multiple aspects, enabling multi-dimensional verification of vehicle identity. Matching the charging station information ensures successful verification, effectively preventing tampering and counterfeiting, guaranteeing charging safety, ensuring a smooth charging handshake process, and improving charging reliability.

[0160] In an optional embodiment, the second message may also include at least one of vehicle manufacturer information, vehicle model, and vehicle function settings.

[0161] The vehicle manufacturer information and model number allow charging stations to accurately identify vehicles for whitelist verification. Vehicle function settings can include features such as scheduled charging, battery insulation, and anti-unplugging of the charging gun. These settings can be reserved for communication with various vehicle manufacturers and charging station providers. Therefore, including vehicle function settings in the second message allows for efficient communication with vehicle manufacturers and charging station providers, accurately adapting to needs and improving the charging service experience and collaborative efficiency.

[0162] In an optional embodiment, the method provided in this disclosure may further include:

[0163] The vehicle reorders the fields in the second message.

[0164] The specific implementation of the vehicle's reordered combination of fields in the second message is similar to that of the charging pile's reordered combination of fields in the first message, and will not be elaborated here.

[0165] In an optional embodiment, the method provided in this disclosure may further include:

[0166] The vehicle stops sending the second message when at least one of the following conditions is met:

[0167] Received the charger handshake message CHM from the charging pile during the charging handshake process;

[0168] Received the charger identification message (CRM) from the charging pile during the charging handshake process;

[0169] The time taken to send the second message has reached the first preset time.

[0170] For example, the first preset duration can be pre-set based on actual needs, such as 5 seconds. For instance, the first preset duration can be determined based on the time from when the user plugs in the charging gun to when they scan the code to start the charging process, thus avoiding interference with the user's charging process after plugging in the gun and scanning the code to start the charging. When the vehicle receives the CHM / CRM, it means the charging station has received the second message and verified it, initiating the subsequent process. To ensure smooth interaction of subsequent messages, the vehicle can stop sending the second message.

[0171] Upon receiving the charging pile's CHM / CRM, the transmission of the second message is stopped to avoid invalid communication; the transmission of the second message is stopped after a first preset time to prevent resource waste. This ensures the orderly progress of the charging handshake process, optimizes the utilization of communication resources, and improves the stability of the collaborative operation between the vehicle and the charging pile.

[0172] In one embodiment, the first message includes charging pile manufacturer information, charging pile model, random number, and the supercharging protocol version of the charging pile. The second message includes vehicle manufacturer information, vehicle model, vehicle identification number, random number, current offset, vehicle function settings, field information processed by a preset algorithm, and the vehicle's supercharging protocol version.

[0173] The mutual verification logic between the first and second messages is as follows:

[0174] Upon receiving the first message, the vehicle verifies the supercharging protocol version. If the version does not match the vehicle's own supercharging protocol, the verification fails, and no second message is sent. Conversely, if they match, the verification passes, and a second message is sent. The vehicle can also identify the charging station manufacturer and model for whitelisting. Additionally, the vehicle can extract a random number from the first message and place it in the second message.

[0175] Upon receiving the second message, the charging pile can verify the random number, the field information processed by a preset algorithm, and the vehicle's Supercharging Protocol version within the second message. If the verification fails, it will no longer respond to the content required by this Supercharging Protocol and will not execute the charging handshake process with the policy; conversely, if the verification passes, it will begin executing the charging handshake process with the vehicle. The charging pile can identify the vehicle identification code, query account information, and deduct fees; identify vehicle function settings and execute functions agreed upon by the vehicle manufacturer and the charging pile manufacturer; and identify the current offset. If the first and second messages pass verification, charging can be performed according to the current offset in the second message in subsequent processes.

[0176] Considering the time difference between establishing a physical connection between the vehicle and the charging station and the scanning operation, in order to further avoid the vehicle forgetting the interaction of the first and second messages due to sleep mode, resulting in charging not being performed according to the offset agreed in the second message, a secondary verification process can be added to ensure that both the vehicle and the charging station are aware of the current offset to be performed by the other party, so as to make corresponding adjustments and achieve a true closed loop of the supercharging protocol.

[0177] In one embodiment, two more private messages may be added to ensure that both the vehicle and the charging station are aware that the other is about to perform a current offset.

[0178] In another embodiment, some message content in the currently widely deployed charging communication protocol (hereinafter referred to as the old national standard for ease of description) can be modified to ensure that both the vehicle and the charging pile are aware that the other party is about to perform a current offset. It should be noted that, apart from the first and second messages, all other messages involved in this disclosure can be messages from the old national standard.

[0179] The old national standard defined reconnection, which means that when the vehicle or charging pile detects a message timeout and terminates the current charging, the charging pile re-initiates the CRM, and the vehicle responds to the BRM to continue charging. If the message before the CRM is modified, the current offset verification will not be performed during reconnection, and the supercharging protocol will not be closed-loop, which may cause a mismatch in current offset between the vehicle and the charging pile. However, messages after the CRM and BRM (such as the charger maximum output capacity message CML and the battery charging parameter message BCP) include current information. Therefore, before CML and BCP, the vehicle and the charging pile need to complete the supercharging protocol closed-loop message exchange to ensure accurate matching of current parameters during subsequent charging, so as to ensure stable and safe charging and avoid failures caused by current issues.

[0180] Therefore, by modifying the CRM and BRM, it can be determined whether both the vehicle and the charging station are aware that the other is about to execute a current offset, thus achieving a true closed loop in the supercharging protocol. The specific interaction process can be as follows: Figure 5 As shown. For ease of understanding, CRM and BRM can be defined as closed-loop messages of the Supercharger protocol.

[0181] Figure 5 A signaling interaction diagram between a vehicle and a charging station is shown according to one embodiment of the charging control method provided in this disclosure. Figure 5 As shown, the method further includes steps S304 to S306, as well as steps S104 and S105.

[0182] In step S304, the charging pile fills the current offset in the second message into the first preset field in the charger identification message CRM.

[0183] For example, the first preset field can be a field for the charging pile number, or other optional fields. Upon receiving the second message and if the second verification information in the second message passes verification, the charging pile can fill the current offset from the second message into the first preset field of the CRM. Filling the CRM with the current offset from the second message indicates that the second verification information in the second message has passed verification, and the charging pile agrees to perform charging according to the current offset in the second message.

[0184] In step S305, the charging pile sends the charger identification message (CRM) to the vehicle.

[0185] In step S104, if the first preset field in the charger identification message CRM received by the vehicle is consistent with the current offset in the second message, the vehicle fills the current offset in the second message into the second preset field in the BMS identification message BRM.

[0186] For example, the second preset field can be the battery pack serial number field, or other optional fields. Filling the BRM with the current offset from the second message indicates that the vehicle has received the CRM, and the informed charging station will perform charging according to the current offset in the second message, and the vehicle will also perform charging according to the current offset in the second message.

[0187] In step S105, the vehicle sends the BMS identification message BRM to the charging station.

[0188] In step S306, if the second preset field in the BMS identification message BRM received by the charging pile is consistent with the current offset in the second message, it is determined that the vehicle and the charging pile will perform charging according to the current offset in the second message.

[0189] exist Figure 5 The technical solution shown can prevent situations where the vehicle or charging pile does not perform charging according to the offset agreed in the second message, but the other party is unaware of this and still performs charging according to the agreed offset, thereby achieving the purpose of ensuring charging safety and improving charging efficiency.

[0190] The vehicle and the charging pile interact according to the requirements of exchanging the first message, the second message, CRM, and BRM. After the verification is successful, the current in the subsequent BCP, CML, BCL, CCS (charger charging status message), and BCS (battery charging status message) is filled according to the current offset defined in the second message.

[0191] Figure 6 A signaling interaction diagram between a vehicle and a charging station is shown according to one embodiment of the charging control method provided in this disclosure. Figure 6 As shown, the method further includes steps S307 to S308, as well as steps S106 and S107.

[0192] In step S307, if a battery charging parameter message BCP is received from the vehicle, the charging pile parses the battery charging parameter message BCP according to the current offset on the charging pile side.

[0193] In step S308, if the analysis result indicates that the direction of the current obtained from the analysis is incorrect, or exceeds the preset maximum current value, the charging pile will end the current charging.

[0194] In step S106, if a charger maximum output capacity message CML is received from the charging pile, the vehicle parses the charger maximum output capacity message CML according to the current offset on the vehicle side.

[0195] In step S107, if the analysis result indicates that the direction of the current obtained from the analysis is incorrect, or exceeds the preset maximum current value, the vehicle will end the current charging.

[0196] For example, the maximum current value can be preset based on actual needs, for instance, it can be set to -2000A. It should be noted that the symbol preceding the current value in this disclosure is used to indicate the charging direction, not the actual current magnitude.

[0197] After receiving CML and BCP respectively, the vehicle and charging station parse the current in the received message according to their own current offset. If the direction of the parsed current is incorrect (such as being positive) or exceeds the preset maximum current value, it can be determined that the current offset is mismatched and the charging is terminated.

[0198] For example, if the vehicle executes a -3000A current offset and the charging pile executes a -400A current offset, and the charging pile sends a maximum and minimum current of (-400A, 0A) respectively, then the CML message content is (0, 400), and the vehicle's parsing result is (-3000A, -2600A), which exceeds the maximum current value, and the offset verification fails. If both the vehicle and the charging pile execute a -3000A offset, and the charging pile sends a maximum and minimum current of (-400A, 0A) respectively, then the CML message content is (2600, 3000), and the vehicle's parsing result is (-400A, 0A), which is within the defined range, and the offset verification passes.

[0199] In this way, by adding current offset verification and charging current maximum limit, it is possible to effectively deal with situations where vehicles or charging piles do not perform charging according to the current offset in the second message due to abnormalities (such as software bugs, extreme scenarios, etc.), timely detect and terminate abnormal charging, ensure charging safety, prevent equipment damage, and improve charging reliability.

[0200] Figure 7 This diagram illustrates the signaling interaction between a vehicle and a charging station when implementing the charging control method provided in this disclosure, according to one embodiment. Figure 7 This allows for a clearer understanding of the charging control method provided in this disclosure.

[0201] like Figure 7As shown, once a physical connection is established with the vehicle, the charging pile sends a CPM (first message) to the vehicle, including charging pile manufacturer information, charging pile model, a random number, and the charging pile's Supercharger protocol version. The vehicle uses the first verification information (the charging pile's Supercharger protocol version) in the CPM for verification. If the verification passes, the vehicle sends a VPM (second message) to the charging pile, including vehicle manufacturer information, vehicle model, vehicle identification number, a random number, current offset, vehicle function settings, field information processed by a preset algorithm, and the vehicle's Supercharger protocol version. The charging pile uses the second verification information (random number, field information processed by a preset algorithm, and the vehicle's Supercharger protocol version) in the VPM for verification. If the verification passes, the charging pile sends a CHM to the vehicle to obtain the BHM (Best Message Management) from the vehicle.

[0202] After the insulation test passes, the charging pile fills the current offset from the VMP into the first preset field of the CRM and sends the CRM (with the first byte being 0x00) to the vehicle. The vehicle verifies whether the current offset in the CRM matches the current offset in the VPM; if they match, it fills the current offset from the VMP into the second preset field of the BRM and sends the BRM to the charging pile. The charging pile verifies whether the current offset in the BRM matches the current offset in the VPM; if they match, it determines that the vehicle and the charging pile will perform charging according to the current offset in the second message, and proceeds with subsequent message interactions.

[0203] The charging station sends a CRM message with the first byte 0xAA to the vehicle to indicate a successful charging handshake and initiate the parameter configuration phase. The vehicle sends a BCP message to the charging station, which parses the BCP according to its own current offset and verifies the parsing result using a preset maximum current value. If the verification passes, the charging station sends a CML message to the vehicle. The vehicle parses the CML according to its own current offset and verifies the parsing result using a preset maximum current value. If the verification passes, subsequent message interactions continue. During the entire interaction process, if any verification fails, the charging session ends.

[0204] Figure 7The technical solution presented has several advantages. First, it has industry-wide application value and high compatibility, reserving rich functional settings to flexibly adapt to different needs. Second, it has a high degree of logical closed-loop, effectively avoiding most current offset mismatch problems and ensuring current stability. Third, it has high security, achieving protocol-level security protection through a combination of complex proprietary message definitions and old national standard message definitions, safeguarding the charging process. Fourth, it has comprehensive scenario coverage, encompassing various common scenarios such as reconnection and sleep mode after plugging in, ensuring stable operation under various conditions. Fifth, it is equipped with redundant verification logic, technically preventing charging overcurrent phenomena, providing reliable safety guarantees for the charging process, and providing solid support for the reliable operation of the charging system.

[0205] Figure 8 This is a block diagram illustrating a charging control device 400 according to an exemplary embodiment. The charging control device 400 is applied to a vehicle, such as... Figure 8 As shown, the charging control device 400 includes:

[0206] The first sending module 401 is configured to, upon receiving a first message from a charging pile, send a second message to the charging pile if the first verification information in the first message passes verification. The second message includes second verification information, a vehicle identification code, and a current offset.

[0207] The first handshake module 402 is used to perform a charging handshake process with the charging pile;

[0208] The first control module 403 is used to adjust the charging current value requested by the vehicle by utilizing the current offset in the second message after the charging handshake process is completed.

[0209] In the above technical solution, a "supercharging" extension mechanism compatible with existing protocols is constructed by adding the interaction of a first message and a second message before the charging handshake. Before the charging handshake process is completed, the vehicle sends a second message including a current offset to the charging pile, allowing the charging pile to know the current adjustment requirement in advance and adjust its output current accordingly. The vehicle also uses this current offset to adjust the charging current value requested by the vehicle. In this way, while ensuring that the current offsets at both ends are matched, the hardware potential of the vehicle and the charging pile can be fully utilized. By using the current offset to overcome the inherent current limit, the charging current value can be increased, the charging time of electric vehicles can be shortened, and charging safety can be ensured at the same time, while meeting the user's fast charging needs. By setting the first verification information in the first message and sending the second message after successful verification, incorrect charging pile access can be prevented, ensuring charging safety. The second verification information in the second message can also play a role in preventing tampering and counterfeiting.

[0210] In some possible implementations, the first verification information includes the Supercharging protocol version of the charging pile; the first sending module 401 is used to send a second message to the charging pile in the following manner:

[0211] If the supercharging protocol version of the charging pile matches the supercharging protocol version of the vehicle, then the first verification information is determined to be verified, and the second message is sent to the charging pile.

[0212] In some possible implementations, the first message may also include a random number.

[0213] In some possible implementations, the first message may also include at least one of the charging pile manufacturer information and the charging pile model.

[0214] In some possible implementations, the second message may also include at least one of vehicle manufacturer information, vehicle model, and vehicle function settings.

[0215] In some possible implementations, the device 400 further includes:

[0216] The first misalignment module is used to reorder and combine the fields in the second message.

[0217] In some possible implementations, the first sending module 401 is further configured to stop sending the second message when at least one of the following conditions is met:

[0218] Receives a charger handshake message from the charging pile during the charging handshake process;

[0219] Receives a charger identification message from the charging pile during the charging handshake process;

[0220] The duration of sending the second message has reached the first preset duration.

[0221] In some possible implementations, the device 400 further includes:

[0222] The first filling module is used to fill the current offset in the second message into the second preset field of the BMS identification message if the first preset field in the received charger identification message is consistent with the current offset in the second message. The charger identification message is sent by the charging pile.

[0223] The first sending module 401 is also used to send the BMS identification message to the charging pile.

[0224] In some possible implementations, the device 400 further includes:

[0225] The first verification module is used to parse the maximum output capacity message of the charger according to the current offset on the vehicle side if it receives the maximum output capacity message of the charger sent by the charging pile.

[0226] The first control module 403 is also used to terminate the current charging if the analysis result indicates that the direction of the current obtained by the analysis is incorrect or exceeds the preset maximum current value.

[0227] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0228] Figure 9 This is a block diagram illustrating a charging control device 500 according to an exemplary embodiment. The charging control device 500 is applied to a charging pile, such as... Figure 9 As shown, the charging control device 500 includes:

[0229] The second sending module 501 is used to send a first message to the vehicle when a physical connection is established between the vehicle and the charging pile. The first message includes first verification information.

[0230] The second handshake module 502 is used to perform a charging handshake process with the vehicle if the second verification information in the second message passes the verification when the second message is received. The second message also includes a vehicle identification code and a current offset.

[0231] The second control module 503 is used to adjust the charging current value output by the charging pile by utilizing the current offset in the second message after the charging handshake process is completed.

[0232] In the above technical solution, a "supercharging" extension mechanism compatible with existing protocols is constructed by adding the interaction of a first message and a second message before the charging handshake. Before the charging handshake process is completed, by receiving the current offset in the second message sent by the vehicle, the charging pile can understand the vehicle's charging current adjustment needs in advance before the charging handshake process is completed, and set the output current more accurately. The vehicle will also use this current offset to adjust the charging current value requested by the vehicle. In this way, while ensuring that the current offsets at both ends are matched, the hardware potential of the vehicle and the charging pile can be fully utilized. By using the current offset to break through the inherent current limit, the charging current value can be increased, the charging time of electric vehicles can be shortened, and charging safety can be ensured at the same time to meet the user's fast charging needs. The first verification information in the first message can effectively prevent incorrect charging pile access, ensuring charging safety from the source. The second verification information in the second message has anti-tampering and anti-counterfeiting functions.

[0233] In some possible implementations, the second verification information includes at least one of the following: the vehicle's supercharging protocol version, field information processed by a preset algorithm, and a random number in the first message; the second handshake module 502 is used to perform a charging handshake process with the vehicle in the following manner: if the second verification information matches the corresponding information in the charging pile, then the second verification information is determined to be verified, and a charging handshake process is performed with the vehicle.

[0234] In some possible implementations, the preset algorithm is synchronized in the charging station and the vehicle.

[0235] In some possible implementations, the second message may also include at least one of vehicle manufacturer information, vehicle model, and vehicle function settings.

[0236] In some possible implementations, the first message may also include at least one of the charging pile manufacturer information and the charging pile model.

[0237] In some possible implementations, device 500 further includes:

[0238] The second misalignment module is used to reorder and combine fields in the first message.

[0239] In some possible implementations, the second sending module 501 is further configured to stop sending the first message when at least one of the following conditions is met:

[0240] The second message was received;

[0241] The duration of sending the first message has reached the second preset duration.

[0242] In some possible implementations, the second sending module 501 is used to send a first message to the vehicle in the following manner:

[0243] Once a physical connection is established between the vehicle and the charging station, and the user is detected performing a scanning operation after the connection duration has reached a third preset duration, the first message is sent to the vehicle.

[0244] In some possible implementations, the device 500 further includes:

[0245] The second filling module is used to fill the current offset in the second message into the first preset field in the charger identification message;

[0246] The second sending module 501 is also used to send the charger identification message to the vehicle.

[0247] In some possible implementations, the device 500 further includes:

[0248] The second verification module is used to determine that the vehicle and the charging pile will perform charging according to the current offset in the second message if the second preset field in the BMS identification message sent by the vehicle is consistent with the current offset in the second message.

[0249] In some possible implementations, the device 500 further includes:

[0250] The third verification module is used to parse the battery charging parameter message according to the current offset on the charging pile side if a battery charging parameter message sent by the vehicle is received.

[0251] The second control module is also used to terminate the current charging if the analysis result indicates that the direction of the current obtained from the analysis is incorrect or exceeds the preset maximum current value.

[0252] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.
