Description

Technical Field

[0001] The present invention relates to the field of vehicles, and in particular to an adaptation method, device, equipment and medium for vehicle charging. Background Art

[0002] With the rapid development of the electric vehicle industry, the market demand for charging facilities has increased dramatically, prompting the emergence of multiple brands of charging piles. However, due to the update and non-uniformity of charging standards, there are currently two versions of charging standards in the market, 2011 and 2015. This results in different communication message formats for charging piles of different brands, which poses a challenge to the charging compatibility of the battery management system (Battery Management System).

[0003] Compared with the 2011 version, the 2015 version mainly adds the Charge Handshake Message and the Battery Handshake Message, and adjusts the priority of long frame messages (such as the Battery Recognition Message, the Battery Charging Profile, and the Battery Charge Status), which is specifically manifested in the change of the data length of the Battery Recognition Message and the difference in priority. For example, the priority of the Battery Charging Profile Message in the 2015 version of the standard is 7, while it is 6 in the 2011 version of the standard, which will lead to changes in the message identifier.

[0004] Since there are charging pile devices that do not meet a single standard on the market, such as charging piles that do not have a charging handshake message but use the 2015 priority, the battery management system and the charging pile cannot match during charging. Therefore, there is room for improvement. Summary of the invention

[0005] The object of the present invention is to provide a vehicle charging adaptation method, device, equipment and medium, which can match a battery management system with a charging pile.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention provides a vehicle charging adaptation method, which is applied to a battery management system, wherein the battery management system is connected to a charging pile through a first standard protocol or a second standard protocol, and the adaptation method includes:

[0010] Within a preset time period, determining whether charging response information fed back by the charging pile according to the charging request information is received;

[0011] If a charging response message is received, the charging pile is connected to the communication according to the standard protocol type to charge;

[0012] If the charging response information is not received, the restart process is entered, the standard protocol type is changed, the priority content in the charging request information is updated and sent; until the corresponding charging response information is received, and the charging pile is communicated and connected according to the standard protocol type to charge.

[0013] In one embodiment of the present invention, the step of identifying the standard protocol type through the communication request information and sending the charging request information to the charging pile according to the standard protocol type includes:

[0023] Enter the restart process;

[0024] Change the protocol type and update the priority content in the charging request information accordingly;

[0025] Sending updated charging request information to the charging pile;

[0026] Check whether the charging response information corresponding to the updated charging request information is received:

[0027] If the corresponding charging response information is received, a communication connection is established with the charging pile according to the standard protocol type for charging;

[0028] If the corresponding charging response information is not received, the restart process is started again until the corresponding charging response information is received, and the charging pile is communicated and connected according to the standard protocol type to perform charging.

[0029] In one embodiment of the present invention, the step of changing the standard protocol type, updating the priority content in the charging request information and sending it includes:

[0030] When the type of the charging request information belongs to the type of the first standard protocol, changing the protocol type to the second standard protocol, and updating the priority content in the charging request information according to the second standard protocol and sending it;

[0033] If the corresponding charging response information is not received, the number of times the restart process is entered is counted;

[0034] When the number of times the restart process is entered reaches the preset number, charging is terminated;

[0035] Otherwise, the restart process is started again until the corresponding charging response information is received, and the charging pile is communicated and connected according to the standard protocol type to charge.

In the event that a priority mismatch is detected, the battery management system is allowed to dynamically update the priority content in the charging request information to adapt to charging piles of different versions (such as charging piles with 2011 mixed with 2015 priorities), ensuring that the charging request can be successfully matched. Not only is the compatibility with the 2011 version of the standard charging pile enhanced, but support for the 2015 version of the standard charging pile is also retained, achieving adaptation to a wide range of charging pile types and avoiding the risk of charging failure due to version differences.

[0046] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1 The present invention provides a vehicle charging adaptation method, which is applied to a battery management system, wherein the battery management system is connected to a charging pile through a first standard protocol or a second standard protocol. The adaptation method may include the following steps:

[0054] Step S10, receiving communication request information sent by the charging pile;

[0055] Step S20: Identify the standard protocol type through the communication request information, and send charging request information to the charging pile according to the standard protocol type;

[0056] Step S30: within a preset time period, determine whether charging response information fed back by the charging pile according to the charging request information is received;

[0057] Step S40: If charging response information is received, communicate with the charging pile according to the standard protocol type to charge;

[0058] Step S50: If the charging response information is not received, enter the restart process, change the standard protocol type, update the priority content in the charging request information and send it; until the corresponding charging response information is received, and communicate with the charging pile according to the standard protocol type to charge.

[0059] In one embodiment, when step S10 is executed, specifically, when the vehicle approaches the charging pile and makes a physical connection, that is, the charging head of the charging pile is connected to the charging port of the vehicle, the charging process is automatically started. At this time, the charging pile needs to establish a communication connection with the battery management system of the vehicle to ensure the safety and efficiency of the charging process.

[0060] In one embodiment, after the connection between the vehicle and the charging pile is completed, the charging pile first sends a communication request message to the battery management system of the vehicle. Since the charging pile may follow different charging standards (2011 or 2015 version of the standard), the content included in the communication request message is different for different versions of the charging standard. For example, since the Charge Handshake Message is only applicable to the charging standard of the 2015 version of the standard, for the charging standard of the 2015 version of the standard, the communication request message sent by the charging pile can be a Charge Handshake Message. For another example, the Charge Recognition Message is applicable to the charging standard of the 2011 version of the standard. For the charging standard of the 2011 version of the standard, the communication request message sent by the charging pile can be a Charge Recognition Message.

[0061] In one embodiment, when step S20 is executed, specifically, step S20 may include the following steps:

[0062] Step S21, identifying the type of communication request information;

[0063] Step S22: When the type of the communication request information belongs to the type under the first standard protocol, send the charging request information to the charging pile according to the first standard protocol;

[0064] Step S23: When the type of the communication request information belongs to the type under the second standard protocol, send the charging request information to the charging pile according to the second standard protocol.

[0065] In one embodiment, when executing step S21, specifically, for a charging pile of the 2011 version of the charging standard, it can be indicated that the communication protocol between the charging pile and the battery management system is the first standard protocol. For a charging pile of the 2015 version of the charging standard, it can be indicated that the communication protocol between the charging pile and the battery management system is the second standard protocol.

[0066] In one embodiment, when the battery management system receives the communication request information sent by the charging pile, it can immediately parse the content of the communication request information to determine whether it belongs to the type under the first standard protocol, that is, the charging identification message type.

[0067] In one embodiment, for communication request information that meets the first standard protocol, its type may be a charging identification message type. For communication request information that meets the second standard protocol, its type may be a charging handshake message type. In the charging identification message and the charging handshake message, the contents contained in the identifier are different. The battery management system can determine whether the communication request information belongs to the type under the first standard protocol by identifying the identifier content of the communication request information.

[0068] In one embodiment, when executing step S22, specifically, if the battery management system confirms that the received communication request information is not a charging handshake message of the 2015 version standard, the battery management system can send a charging request message to the charging pile to re-establish a communication connection.

[0069] In one embodiment, when executing step S23, specifically, if the battery management system confirms that the received communication request information is a charging handshake message of the 2015 version of the standard, then the battery management system will establish a communication connection with the charging pile in accordance with the protocol of the 2015 version of the standard. At this time, both parties will share necessary charging parameters, such as maximum charging capacity, voltage level and safety protocol to optimize the charging process. Once the communication connection is successfully established, the battery management system and the charging pile begin the formal charging process. The charging strategy implemented in accordance with the 2015 version of the standard will ensure maximum charging efficiency and reduce battery wear.

[0070] In one embodiment, when the battery management system establishes a communication connection with the charging pile according to the protocol of the 2015 version of the standard, the battery management system can send a charging request message to the charging pile, and the charging request message can adopt a long frame message format to meet the communication requirements of the 2015 version of the standard. The charging request message can include a data header (1CEC56F4x) and data content (10310007FF000200). The 1C in the data header indicates the priority of the message, and 1C indicates that the priority content is 7. The first byte of the data content is 10, indicating that the battery management system requests long frame communication.

[0071] In one embodiment, the charging pile can parse the received charging request information to identify the priority content. During the parsing process, if the priority content of the corresponding long frame message set in the charging pile is also 7, it complies with the 2015 version of the standard, and the charging pile will continue to process the request. The charging pile generates and sends a charging response message. The charging response message may include a data header (1CECF456x) and data content (110701FFFF000200). The first byte of the data content is 11, indicating that the charging pile agrees to long frame communication.

[0072] In one embodiment, after receiving the charging response information from the charging pile, the battery management system prepares to send relevant battery information. The battery management system can load the battery information according to the second standard protocol (the charging standard of the 2015 version of the standard). The battery information may include a specific data header and data content. The data content may cover the current status information of the battery, such as: battery rated voltage, rated capacity, battery type, etc. After the transmission is completed, the battery management system waits for the confirmation information from the charging pile to ensure that the communication between the two parties is fully synchronized and the data is fully received.

[0073] In one embodiment, after successfully receiving and processing the battery information, the charging pile is ready to send a message reception identification completion message to notify the battery management system that the next stage of the message interaction process can begin. The message reception identification completion message may include a data header (1CECF456x) and data content (13310007FF000200). In the data content, the first byte 13 indicates that the long frame data reception has ended, indicating that the charging pile has completed the identification and started the parameter configuration phase.

[0074] In one embodiment, after receiving the message reception and identification completion information, the battery management system performs a final system check to ensure that the battery status and the vehicle electronic equipment are in a safe state for charging. After confirmation, the battery management system begins to control the introduction of power into the battery. This process will follow the previously set parameters to charge at the optimal power and current.

[0075] In one embodiment, during the process of the battery management system interacting with the charging pile through the second standard protocol, the charging request information, the charging response information, the battery information, and the message reception and identification completion information can be combined to form a complete battery identification message.

[0076] In one embodiment, when step S40 is executed, specifically, step S40 may include the following steps:

[0077] Step S41: Sending battery information to the charging pile according to the identified standard protocol type;

[0078] Step S42: The receiving charging pile receives the recognition completion information according to the message feedback of the battery information to carry out charging.

[0079] In one embodiment, when executing step S41, specifically, after receiving the charging response information of the charging pile, the battery management system prepares to send relevant battery information. The battery management system can load the battery information according to the first standard protocol (the charging standard of the 2011 version standard) or the second standard protocol (the charging standard of the 2015 version standard).

[0080] In one embodiment, when executing step S42, specifically, after successfully receiving and processing the battery information, the charging pile is ready to send a message receiving identification completion information and a charging identification message to notify the battery management system that the parameter configuration process can be started. The message receiving identification completion information may include a data header and data content.

[0081] In one embodiment, after receiving the message reception and identification completion information, the battery management system performs parameter configuration and system checks to ensure that the battery status and the vehicle electronic equipment are in a safe state for charging. After confirmation, the battery management system begins to control the introduction of power into the battery. This process will follow the previously set parameters and charge at the optimal power and current.

[0082] In one embodiment, when step S50 is executed, specifically, step S50 may include the following steps:

[0083] Step S511, sending timeout request information to the charging pile;

[0084] Step S512, receiving the timeout information sent by the charging pile according to the timeout request information;

[0085] Step S513, entering the restart process according to the timeout information;

[0086] Step S514: change the standard protocol type and update the priority content in the charging request information to send the updated charging request information to the charging pile.

[0087] In one embodiment, when executing step S511, after the battery management system identifies that the charging pile uses the 2011 version of the standard, the battery management system can send a charging request message to the charging pile, and the charging request message adopts a long frame message format to meet the communication requirements of the 2011 version of the standard. The charging request message may include a data header (18EC56F4x) and data content (10290006FF000200). The priority in the data header may be 18, and the number 18 indicates that the priority content is 6.

[0088] In one embodiment, the charging pile can parse the received charging request information to identify the priority content. Although the charging pile is physically a charging pile of the 2011 version standard, it may still be configured with a parsing mechanism compatible with the 2015 version standard. During the parsing process, if the priority content of the corresponding long frame message set in the charging pile is also 6, it complies with the 2011 version standard, the charging pile will continue to process the request, and the charging pile generates and sends a charging response message.

[0089] In one embodiment, the priority content of the charging request message sent by the battery management system is 6, which complies with the 2011 standard set internally. However, the charging pile sets the long frame message priority content to 7, so it complies with the 2015 version of the standard, resulting in a failure in the charging request priority match. Due to the priority mismatch, the charging pile identifies the request message as substandard and will not respond to the message reception and identification completion information of the battery management system.

[0090] In one embodiment, when step S512 is executed, specifically, when the battery management system does not receive the message reception and identification completion information within a preset time (e.g., 1.25s), the communication timeout determination mechanism is started. After confirming the communication timeout, the battery management system can send a timeout request message to the charging pile in accordance with the SAE-J1939 communication standard to express the monitoring results of the current communication status. The timeout request information includes a data header (18EC56F4x) and data content (FF03FFFFFF000200). Among them, the first byte FF of the data content represents the message type, and the following byte 03 indicates that the timeout has caused the message interaction to be interrupted.

[0091] In one embodiment, when executing step S513 and step S514, specifically, after the charging pile receives the timeout request information sent by the battery management system, it will generate and send a timeout message to indicate that the timeout notification has been received and the corresponding processing has been performed. Among them, the timeout information follows the charging error management (Charging Error Management) message standard, which can be associated with the errors encountered in the electric vehicle communication message (such as battery identification message, battery charging configuration message, battery charging status message). After receiving the timeout information, the battery management system can enter the restart process and parse the message to determine the specific error situation.

[0092] In one embodiment, the battery management system sends a charging request message to the charging pile, and its priority content is 6, which complies with the first standard protocol. After receiving the request, the charging pile finds that the long frame message priority content it sets is 7, which complies with the second standard protocol, which causes the priority matching between the two to fail. Due to the priority mismatch, the charging pile does not reply with the message reception and identification completion information. The battery management system detects a communication interruption and enters the restart process.

[0093] In one embodiment, when executing step S50, specifically, step S50 may further include the following steps:

[0094] Step S521, entering the restart process;

[0095] Step S522: changing the protocol type and correspondingly updating the priority content in the charging request information;

[0096] Step S523: Send updated charging request information to the charging pile;

[0097] Step S524: Detect whether the charging response information corresponding to the updated charging request information is received:

[0098] Step S525: if the corresponding charging response information is received, a communication connection is established with the charging pile according to the standard protocol type to perform charging;

[0099] Step S526: If the corresponding charging response information is not received, the restart process is started again until the corresponding charging response information is received, and the charging pile is communicated and connected according to the standard protocol type to perform charging.

[0100] In one embodiment, when executing steps S521, S522, S523, S524, S525 and S526, specifically, after updating the priority of the charging request information, the battery management system can send the updated charging request information to the charging pile through the standard protocol. At this time, the priority content of the charging request information matches the requirements of the charging pile, and it is expected that communication can be successfully established and the charging process can be started.

[0101] In one embodiment, after sending the updated charging request information to the charging pile through the standard protocol, the battery management system can again detect whether the corresponding charging response information is received; if the corresponding charging response information is received, a communication connection is established for charging; if the corresponding charging response information is not received, the restart process is started again.

[0102] In one embodiment, when executing step S50, specifically, step S50 may further include the following steps:

[0103] Step S531: when the type of the charging request information belongs to the type of the first standard protocol, the protocol type is changed to the second standard protocol, and the priority content in the charging request information is updated and sent according to the second standard protocol;

[0104] Step S532: When the type of the charging request information belongs to the type of the second standard protocol, the protocol type is changed to the first standard protocol, and the priority content in the charging request information is updated and sent according to the first standard protocol.

[0105] In one embodiment, when executing step S531, specifically, after entering the restart process, when the type of the charging request information belongs to the type of the first standard protocol, the priority content in the charging request information is updated according to the second standard protocol. Specifically, when the battery management system determines that the priority content of the charging request information is 6 (in compliance with the first standard protocol), and the charging pile requires a priority of 7 in compliance with the second standard protocol, the battery management system updates the priority content of the charging request information to 7, and the updated charging request information will be repackaged and sent to the charging pile.

[0106] In one embodiment, when executing step S532, specifically, after entering the restart process, when the type of the charging request information belongs to the type of the second standard protocol, the priority content in the charging request information is updated according to the first standard protocol. Specifically, when the priority content of the charging request information at this time is 7 (in compliance with the second standard protocol), but the charging pile requires a priority of 6 in compliance with the first standard protocol, the battery management system updates the priority content of the charging request information to 6, and the updated charging request information will be repackaged and sent to the charging pile.

[0107] In one embodiment, when executing step S50, specifically, step S50 may further include the following steps:

[0108] Step S541: If the corresponding charging response information is not received, the number of times the restart process is entered is counted;

[0109] Step S542: When the number of times of entering the restart process reaches a preset number, the charging is terminated;

[0110] Step S543: Otherwise, the restart process is started again until the corresponding charging response information is received, and the charging pile is communicated and connected according to the standard protocol type to charge.

[0111] In one embodiment, when executing step S541, step S542 and step S543, specifically, when the battery management system enters the restart process for the first time, since the priority content of the charging request information is 6, it needs to be updated to 7 so that the priority content of the updated charging request information can match the charging pile. When the charging pile believes that the priority content of the updated charging request information matches the priority content of the corresponding long frame message set internally, the corresponding message reception and identification completion information can be fed back to the battery management system for subsequent processes. At this time, the number of times the battery management system enters the restart process can be counted.

[0112] In one embodiment, after entering the restart process for the first time, if the charging pile believes that the priority content of the updated charging request information does not match the priority content of the corresponding long frame message set internally, the charging pile will not feedback the corresponding message reception and identification completion information. When the battery management system does not receive the message reception and identification completion information within the preset time, it can enter the restart process again.

[0113] In one embodiment, when the battery management system enters the restart process for the second time, since the priority content of the charging request information has been updated to 7, it needs to be updated to 6, and the updated charging request information is sent to the charging pile so that the charging pile makes another judgment.

[0114] In one embodiment, each time the battery management system enters the restart process, the priority content of the charging request information needs to be updated, and the priority content of the charging request information can change cyclically between 6 and 7. When the battery management system enters the restart process for a preset number of times (for example, 3), it is necessary to determine whether the corresponding charging response information is received. If the battery management system is able to receive the corresponding charging response information after entering the restart process once, it communicates with the charging pile according to the identified standard protocol type to charge, and the battery management system needs to exit the restart process. If the battery management system has not received the corresponding charging response information after entering the restart process for a preset number of times, and charging cannot be performed, it indicates that charging has failed and charging is terminated.

[0115] It can be seen that in the above scheme, by analyzing and being compatible with charging pile messages of different versions (such as the 2011 and 2015 versions of the standard) and utilizing the feature of being able to restart multiple times after a communication timeout, the charging compatibility of the battery management system is significantly improved. When a priority mismatch is detected, the battery management system is allowed to dynamically update the priority content in the charging request information to adapt to charging piles of different versions (such as charging piles with 2011 mixed with 2015 priorities) to ensure that the charging request can be successfully matched. Not only is the compatibility with the 2011 version of the standard charging pile enhanced, but support for the 2015 version of the standard charging pile is also retained, achieving adaptation to a wide range of charging pile types and avoiding the risk of charging failure due to version differences.

[0116] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0117] See also Figure 2 The present invention also provides a vehicle charging adaptation method, and the adaptation device corresponds to the adaptation method in the above embodiment. The adaptation device may include an information receiving module 100, an information identification module 200, and an information judgment module 300. The functions of each module are as follows:
