[0002] With the rapid development of electric vehicles in China, more and more domestic automakers have begun to sell electric vehicles to Southeast Asia, the Middle East, Europe and other European standard charging areas, which requires the entire vehicle to support European standard charging. The European standard slow charging is not much different from the national standard, and both are involved in controllers such as the battery management system BMS, the on-board charger OBC and the vehicle controller VCU. However, there are significant differences in the communication methods of European standard fast charging and national standard fast charging. The mainstream solution for domestic automakers to be compatible with European standard charging is to install a communication protocol converter EVCC on the entire vehicle as a bridge for the battery management system BMS to interact with the European standard charging pile signal, thereby achieving the fast charging function. Therefore, domestic automakers' vehicles compatible with European standard charging generally come with a communication protocol converter EVCC.

[0003] Regarding the development of battery management system (BMS) software, the national standard software and the European standard software are basically the same in terms of power on and off, thermal management and other functions. However, due to differences in charging logic, the national standard software and the European standard software are usually developed separately, and software compatibility cannot be achieved. Status control and software maintenance are relatively complicated, resulting in waste of resources. Summary of the Invention

DETAILED DESCRIPTION

[0019] To facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings. The detailed description is complete, but it should not be construed as limiting the scope of the present invention. Obvious variations and alternative forms of the following examples are all within the scope of protection of this patent.

[0020] Reference Figure 1In an embodiment of the present application, a method for configuring a charging standard is provided. The application scenario of the method is to preset the charging standard in the battery management system (BMS) during the first charging after a vehicle rolls off the production line. The selected charging standard is either the national standard or any other charging standard that requires the use of a communication protocol converter (Electric Vehicle Communication Controller, EVCC) to communicate with the battery management system (BMS). The method specifically includes: S101, when the vehicle is charged for the first time after being offline, determining whether any frame message sent by the communication protocol converter EVCC is received; S102, if any frame of message sent by the communication protocol converter EVCC is received, identifying the charging standard of the vehicle as the first charging standard, and presetting the value of the preset flag bit to the first preset flag bit; S103, if any frame of message sent by the communication protocol converter EVCC is not received, identifying the charging standard of the vehicle as the second charging standard, and presetting the value of the preset flag bit to the second preset flag bit; The preset flag is used for the battery management system BMS to confirm the unique charging standard configured for the vehicle when the vehicle is subsequently charged.

[0021] The vehicle rollout phase refers to the stage after the vehicle completes all production and assembly processes and is about to be delivered to users or released to the market. The first charge after a vehicle rolls off the assembly line is the first charging process performed after the vehicle rolls off the assembly line, which initializes the vehicle's battery management system (BMS) and related configurations. The first charge is a critical time point. By presetting the charging standards at this stage, the vehicle is correctly configured for subsequent charging processes.

[0022] A message is a data unit in the communication process. The communication protocol converter EVCC sends and receives messages when communicating with the battery management system BMS. If the battery management system BMS receives any frame of message sent by the communication protocol converter EVCC, it means that the communication protocol converter EVCC is involved in the work, and the communication protocol converter EVCC will only work under specific standards. Therefore, in this case, the vehicle's charging standard is identified as the first charging standard.

[0023] In the embodiments of the present application, the first charging standard and the second charging standard refer to charging standards that comply with international standards or specific market standards. The first charging standard is, for example, ISO 15118 (European standard) or SAE J1772 (American standard), and the second charging standard is, for example, the Chinese standard. For example, a preset flag bit of 0 indicates Chinese standard charging, and a preset flag bit of 1 indicates European standard charging or American standard charging.

[0024] When the vehicle's charging standard is identified as the first charging standard, the preset flag is set to the first preset flag, allowing the vehicle to automatically identify and use the first charging standard for fast charging during subsequent charging. This configuration ensures that the vehicle can charge normally on charging equipment that supports the first charging standard, while utilizing that charging standard for fast and intelligent charging of the vehicle.

[0025] In an embodiment of the present application, when the battery management system BMS does not receive any frame message sent by the communication protocol converter EVCC within a specified time, the vehicle's charging standard is identified as the second charging standard, which can also achieve the preset of the vehicle's charging standard.

[0026] For the vehicle, during each subsequent charge, the battery management control system (BMS) only needs to read the value of a preset flag to quickly determine the vehicle's current charging standard and communicate and charge according to that charging standard. There is no need to match the charging standard every time.

[0027] In this embodiment of the present application, since the battery management system (BMS) uses any message frame sent by the communication protocol converter (EVCC) to identify the charging standard, the aforementioned charging protocol configuration method is applicable to both OFF and ON charging scenarios. Specifically, during OFF charging, the communication protocol converter (EVCC) wakes up before the battery management system (BMS), allowing the EVCC to send messages to the BMS normally. During ON charging, both the EVCC and the BMS are already awake, allowing the EVCC to send messages to the BMS normally. Therefore, regardless of whether the vehicle is charging in OFF or ON mode, if the vehicle supports the European standard, the BMS will normally receive the message from the EVCC and complete the charging process determination. This allows the vehicle to configure the charging standard in any gear (OFF or ON), improving charging compatibility and reliability.

[0028] In the embodiment of the present application, if the battery management system BMS fails to receive the message sent by the communication protocol converter EVCC, it means that normal communication cannot be established between the vehicle and the charging device. This situation may occur in the following scenarios: The communication protocol converter EVCC has a hardware failure or a communication failure; The battery management system BMS has a hardware failure or communication failure; The communication protocol converter EVCC and the battery management system BMS are normal, but the charging standard supported by the vehicle does not match the charging standard of the charging pile.

[0029] In order to avoid the situation where the charging standard is mistakenly identified as the second charging standard due to a failure of the communication protocol converter EVCC and / or the battery management system BMS, it is necessary to correct the value of the preset flag. In the embodiment of the present application, the operator already knows which type of charging standard the vehicle currently needs to be configured with when inserting the gun into the charging pile; therefore, the operator can judge whether the value after the setting of the aforementioned step S103 is accurate based on the value after the preset flag is set. When it is determined that the value after the setting of the aforementioned step S103 is wrong, manual correction is required, that is, correction is performed through diagnostic equipment. Furthermore, in the embodiment of the present application, after setting the value of the preset flag to the second preset flag, the method further includes: S104, after the vehicle is connected to the diagnostic device, receiving the preset flag bit update information written by the diagnostic device; S105: Update the value of the preset flag from the second preset flag to the first preset flag according to the preset flag update information.

[0030] It should be clear that the process of step S104 and step S105 should occur after the vehicle stops charging, and it is necessary to manually connect the diagnostic device to the vehicle to correct the value of the preset flag.

[0031] By adding a manual intervention and correction mechanism, operators can manually update the preset flag values ​​through diagnostic equipment. This approach not only improves the accuracy of the preset flags but also provides operators with the opportunity to intervene, ensuring that the vehicle's charging standard configuration accurately reflects the vehicle's actual support conditions. In this way, the vehicle can complete the charging standard configuration in any state (OFF or ON), and any errors can be corrected promptly, improving the vehicle's charging compatibility and reliability.

[0032] In an embodiment of the present application, when the first charging standard is the European charging standard and the second charging standard is the national charging standard, after completing the presetting of the charging standard of the vehicle, in order to realize charging of the vehicle, in an embodiment of the present application, the method further includes: S106 , performing charging mode identification based on the received CP signal (Control Pilot) and CC signal (Charging Confirmation), or based on the received PP signal (Proximity Pilot) and CP signal.

[0033] By detecting the CP signal, CC signal and PP signal, the vehicle's battery management system BMS can identify the current charging mode, such as AC charging mode, DC charging mode, etc.

[0034] Different charging standards (such as GB / T18487, ISO 15118, SAE J1772, etc.) use different signal combinations to identify charging modes. By detecting these signals, the vehicle can support multiple charging standards, further improving vehicle compatibility.

[0035] Specifically, when the vehicle's current charging standard is the national standard, if both the CP and CC signals are normal, the battery management system (BMS) identifies it as AC charging mode and adjusts charging parameters according to a preset charging standard (such as GB / T18487). When the vehicle's current charging standard is the national standard, if both the PP and CP signals are normal, the battery management system (BMS) identifies it as DC charging mode and adjusts charging parameters according to a preset first charging standard.

[0036] After presetting the vehicle's charging standard, the system detects the CP, CC, and PP signals for charging mode identification, ensuring the vehicle can charge correctly on different types of charging devices. This approach not only improves the vehicle's charging compatibility and safety, but also optimizes the charging process and supports multiple charging standards. In this way, the vehicle can charge seamlessly on any supported charging device, enhancing the user experience.

[0037] The above method in the embodiment of the present application enables the battery management system BMS software to achieve charging compatibility with national standards and other standards without increasing hardware development, which can reduce the battery pack software status and facilitate management and production.

[0038] During the vehicle's first charge, the charging standard is identified by detecting whether the communication protocol converter (EVCC) sends any message frame. The preset flag bit is then set to the value corresponding to the charging standard, completing the presetting of the charging standard. This method not only ensures that the charging standard is correctly identified during the vehicle's first charge, but also provides an accurate reference for subsequent charges, improving the vehicle's charging compatibility and reliability. Furthermore, the accuracy of the presetting is further ensured through manual intervention and diagnostic equipment correction mechanisms.

[0039] like Figure 2As shown, for the European standard charging system, its European standard charging seat includes a PP port, a CP port, and universal socket temperature detection, high voltage detection port and electronic lock interface. Among them, the universal socket temperature detection, high voltage detection port and electronic lock interface parts are not reflected in the embodiment of this application. The PP port is used to confirm the charging connection and is detected by the battery management system BMS. The CP port is used to identify European standard DC charging and European standard AC charging, which are detected by the communication protocol converter EVCC and the on-board charger OBC respectively.

[0040] like Figure 3 As shown, for the national standard charging system, its national standard charging seat includes a CC port, a CC2 port, a CP port, as well as universal socket temperature detection, a high-voltage detection port, and an electronic lock interface. The universal socket temperature detection, high-voltage detection port, and electronic lock interface are not reflected in the embodiment of this application. Among them, the CC2 port is used to confirm the connection of the DC charging gun, and the CC port is used to confirm the connection of the AC charging gun. The CC signal and CC2 signal are both collected by the battery management system BMS; the CP port is used to confirm the capacity of the AC charging pile, and the CP signal is detected by the on-board charger OBC.

[0041] The communication protocol converter EVCC collects the CP signal on the European standard charging seat to determine whether it is DC charging under the European standard charging standard. When charging under the European standard charging standard, it converts the European standard charging standard into the national standard CAN protocol content to communicate with the battery management system BMS.

[0042] The on-board charger OBC collects the CP signal of the national standard charging seat or the European standard charging seat, wakes up the charging system according to the CP signal, communicates with the battery management system BMS, and sends the CP value to the battery management system BMS.

[0043] The battery management system (BMS) collects CC signals, CC2 signals, and PP signals and identifies the charging connection status based on the CP signal. It sends charging requirements based on the charging system capabilities and the battery's own charging capabilities, and controls the charging system to charge the power battery.

[0044] In summary, the CC signal and CC2 signal of the national charging standard and the PP signal of the European standard are all collected by the battery management system BMS. Since the national and European standard charging will not exist at the same time, the PP signal of the European standard charging standard can be collected using the channel of the CC signal of the national standard charging standard. That is to say, in the embodiment of the present application, the PP signal of the European standard charging standard and the CC signal of the national standard charging standard share the same collection channel of the battery management system BMS; the CP signal of the national standard charging standard and the CP signal of the European standard charging standard are both collected by the on-board charger OBC and the collection channel is shared. The collected CP signal is sent to the battery management system BMS via CAN communication, and the battery management system BMS makes a unified charging mode judgment. The above realizes compatibility in electrical principles without excessive redundant design and without causing waste of resources.

[0045] On the other hand, refer to Figure 4 , the embodiment of the present application further provides a charging standard configuration device, including: The first flag bit presetting module 201 is configured to, when a vehicle is first charged after being offline, identify the vehicle's charging standard as the first charging standard upon receiving any frame of a message sent by the communication protocol converter EVCC, and presetting the value of the preset flag bit to the first preset flag bit; A second flag bit presetting module 202 is configured to identify the vehicle's charging standard as the second charging standard and presetting the value of the preset flag bit to the second preset flag bit if no frame message sent by the communication protocol converter EVCC is received; The preset flag is used for the battery management system BMS to confirm the unique charging standard configured for the vehicle when the vehicle is subsequently charged.

[0046] In the embodiments of the present application, the first charging standard and the second charging standard refer to charging standards that comply with international standards or specific market standards. The first charging standard is, for example, ISO 15118 (European standard) or SAE J1772 (American standard), and the second charging standard is, for example, the Chinese standard. For example, a preset flag bit of 0 indicates Chinese standard charging, and a preset flag bit of 1 indicates European standard charging or American standard charging.

[0047] In the examples of this application, refer to Figure 4 After setting the preset flag to the second preset flag, the apparatus further includes: The receiving module 203 is used to receive the preset flag bit update information written by the diagnostic device after the vehicle is connected to the diagnostic device; The flag updating module 204 is configured to update the value of the preset flag from the second preset flag to the first preset flag according to the preset flag updating information.

[0048] In the examples of this application, refer to Figure 4 , the device further comprises: The charging mode identification module 205 is configured to identify the charging mode according to the received CP signal and CC signal, or according to the received PP signal and CP signal.

[0049] Preferably, the CC signal and the PP signal are collected through the same signal collection channel.

[0050] In an embodiment of the present application, the PP signal of the European charging standard and the CC signal of the national charging standard share the same acquisition channel of the battery management system BMS; the CP signal of the national charging standard and the CP signal of the European charging standard are both collected by the on-board charger OBC and the acquisition channel is shared. The collected CP signal is sent to the battery management system BMS via CAN communication, and the battery management system BMS makes a unified charging mode judgment.

[0051] The above-mentioned device in the embodiment of the present application is a device consistent with the above-mentioned method and has a technical effect consistent with the above-mentioned method. That is, when the vehicle is charged for the first time, the charging standard is identified by detecting whether the communication protocol converter EVCC sends any frame message, and the preset flag bit is set to the corresponding value, thereby completing the presetting of the charging standard. This method not only ensures that the vehicle correctly identifies the charging standard during the first charging, but also provides an accurate reference for subsequent charging, thereby improving the charging compatibility and reliability of the vehicle. At the same time, the accuracy of the presetting is further ensured through manual intervention and diagnostic equipment correction mechanism.
