[0024] In an embodiment of the present invention, a communication control method of a charging module is provided, which comprises at least the following steps:

[0025] The internal submodules of the charging module communicate with each other via a first communication method, and the charging module communicates with an external device via a second communication method.

[0026] In the embodiment, when the first communication mode is used for communication, the transmitted data includes voltage, current, temperature, and the power and efficiency of the charging module itself. Usually, the internal submodules of the charging module include: a main control module, a power conversion module, a first communication module, a second communication module, a protection module and a status monitoring module. The first communication module is used to support communication in the first communication mode, and the second communication module is used to support communication in the second communication mode. Among them, the first communication mode adopts SCI communication, and the second communication mode adopts CAN communication.

[0027] In the embodiment, when the first communication mode is adopted for communication, the adopted data format includes a sequentially set start identifier, a data length indication, a data content, and a check value. By stipulating the data format of the transmitted data, the data transmission between the internal submodules of the charging module is made more efficient and accurate, which facilitates the main control module to quickly and accurately obtain the status information of each submodule. The charging module can adjust the charging strategy in time according to the voltage, current, temperature and other data monitored in real time, avoid dangerous situations such as overcharging and over-discharging, improve the charging efficiency and ensure the charging safety;

[0028] Through the stable connection and data interaction with external devices through the second communication method, the external device can obtain the execution status and current status of the charging module in real time, realize remote monitoring and fault diagnosis, and users and maintenance personnel can timely understand the working status of the charging module, thereby improving the intelligence level of the charging module and user experience.

[0029] See Figure 1 Specifically, in one implementation of the present invention, the communication control method of the charging module in the embodiment includes the following steps:

[0030] Step S1: when the charging module is started, initializing the first communication module and the second communication module respectively;

[0031] In the embodiment, for the first communication module, the relevant communication parameters of the internal interface of the first communication module are configured, and the relevant communication parameters may include rate, data format, and verification mechanism, and the communication ports corresponding to each internal sub-module are initialized to ensure the normal construction of the communication lines between the internal sub-modules of the charging module;

[0032] For the second communication module, the communication rate, address allocation rules, and screening parameters of the second communication module are set so that the charging module can establish an effective communication link with externally connected electric vehicle control systems, power grid monitoring systems, and other devices;

[0033] Step S2: After the charging module is started, various sensors and detection circuits inside the charging module collect operating data such as voltage, current, temperature, and the power and efficiency of the charging module itself, and encode the collected data in accordance with a predetermined data format corresponding to the first communication method. In the embodiment, a frame of data is composed of a specific start identifier, data length indication, data content, and a format of a check part, so as to enable efficient transmission between internal modules of the charging module.

[0034] In the data collection and transmission of the first communication mode inside the charging module, it is assumed that the voltage collected by the voltage sensor is 380V, the charging current collected by the current sensor is 10A, and the module temperature detected by the temperature sensor is 40°C. According to the data format of the first communication mode, the start identifier is 0xAA in hexadecimal, and the data length indication is 0x06 in hexadecimal, indicating that there are 6 bytes of data behind it. The data content is the voltage value 0x01 0x7C, and the two bytes are combined into 0x017C in hexadecimal, which is 380 in decimal, corresponding to 380V voltage, the current value 0x00 0x0A, and the two bytes are combined into 0x000A in hexadecimal, which is 10 in decimal, corresponding to 10A current, the temperature value 0x000x28, and the two bytes are combined into 0x0028 in hexadecimal, which is 40 in decimal, corresponding to 40°C temperature. The verification part adopts a specific calculation method to obtain a verification value of 0x5F. The calculation of the verification value in the embodiment is to select 0xAA 0x060x01 0x7C 0x00 0x0A The data of 0x000x28 is added and then multiplied by 0xFF, and the lower eight bits are taken to finally get 0x5F. The data packet is 0xAA 0x06 0x01 0x7C0x00 0x0A 0x00 0x28 0x5F. When the transmitted data contains more parameters, the data length indication and data content can be adjusted accordingly. The data content can be added with specific parameter values ​​after the set parameter position.

[0035] Step S3: Communicate between the internal submodules of the charging module through the first communication method, and use the first communication method to transfer the sorted frame data between the main control module and the power conversion module, protection module, status monitoring module and other submodules inside the charging module. In an embodiment of the present invention, the main control module can send the collected status data to the protection module through the first communication method, so that the protection module can adjust the protection strategy in real time according to the data; the power conversion module feeds back its own working status information to the main control module through the first communication method, so as to achieve real-time sharing and collaborative operation of internal information.

[0036] Step S4: The charging module continuously monitors the instructions and data requests sent by the external device through the second communication method. When receiving an instruction from the external device, which may be the battery management system of the electric vehicle, to adjust the charging current or voltage, the message sent by the second communication method is parsed to extract key information in the instruction, such as the target charging parameters and the instruction type.

[0037] When an external instruction is received and processed by the second communication method, for example, a message sent by an external electric vehicle battery management system is received, the message identifier of which is 0x79, and the data content is a requirement to adjust the charging voltage to 400V. The message identifier 0x79 is customized by different manufacturers, and can be defined as 0x79 in the embodiment, or as 0x89. The message is parsed by the second communication method module to extract the target voltage value 400V and the instruction type as voltage adjustment.

[0038] Step S5: Based on the external instruction received by the second communication method, the main control module coordinates the work of each internal submodule of the charging module through the first communication method. For example, if the external instruction is to adjust the charging voltage, the main control module notifies the power conversion module to adjust the charging voltage through the first communication method, and obtains data of other related internal submodules, such as the temperature monitoring module, through the first communication method, so as to ensure the safe and stable operation of the charging module as a whole during the voltage adjustment process.

[0039] Step S6: After the internal submodule completes the corresponding operation according to the external instruction, the main control module will integrate the status information and operation result data of each internal module and package them in the format required by the second communication method protocol. For example, the current output voltage, current, power, internal temperature of the charging module and whether the instruction is successfully executed are packaged, and the packaged data is returned to the external device through the second communication method, so that the external device can know the execution status and current status of the charging module.

[0040] Step S7: During the entire communication process, the operating status of the first communication mode and the second communication mode is monitored in real time. If a fault is detected in the second communication mode, such as line abnormality, connection interruption, or excessive error data, a fault alarm signal of the corresponding communication mode is issued. For a fault in the first communication mode, if an abnormal communication mode between two internal submodules of the charging module is detected, the main control module reinitializes the communication port corresponding to the faulty link and adjusts the communication parameters, which may be to reduce the rate. If normal communication still cannot be restored, the fault information is sent to the external device via the second communication mode for maintenance personnel to conduct maintenance.

[0041] Step S8: Statistics and analysis are performed on the data of the first communication mode and the second communication mode, and the parameters and application strategies of the first communication mode and the second communication mode are optimized based on the statistics and analysis of the long-term communication data. The specific optimization method can be: for the first communication mode and the second communication mode, if it is found that the load of a communication mode is too high in a certain time period, resulting in an increase in data transmission delay, the transmission frequency of some non-critical external data can be appropriately reduced, or the message priority allocation rule of the communication mode can be optimized. For the second communication mode, if the data transmission volume of a certain internal submodule is large for a long time and has high real-time requirements, it can be considered to upgrade the hardware performance of its communication interface, such as replacing a higher-speed interface chip, or adjusting the transmission path of the internal data, reducing the intermediate links of data transmission, and improving the internal communication efficiency.

[0042] Traditional charging modules usually use a single communication method, which makes it difficult to simultaneously meet the complex requirements of efficient collaboration between internal sub-modules and stable connection with multiple external smart devices.

[0043] In the embodiment, when the charging module is started, two specific communication modules for external communication and internal communication of the charging module are respectively initialized, and respective communication parameters are set and connections are established. By separating internal communication from external communication, operating data is collected by the internal sensor of the charging module, and after being sorted and encoded according to the predetermined internal communication module data format, the first communication method is used to transmit data between the main control module and each submodule, so as to achieve internal information sharing and collaboration, which can significantly improve the communication efficiency of the charging module;

[0044] The charging module and the external communication module receive and analyze external commands using the second communication mode. The main control module coordinates the work of the internal submodules through the internal communication module. After completion, the internal state information and operation results are integrated and the external device is replied according to the protocol format of the external communication module. The protocol format of the external communication can also be set according to specific needs. The high compatibility of the external communication ensures seamless connection with various external devices.

[0045] In the embodiment, during the entire communication process, the status of the two communication modes is monitored in real time, and an alarm signal is promptly issued when a fault is detected. For internal communication faults, recovery can be attempted by reinitializing the communication port, adjusting communication parameters, etc. If recovery is not possible, the fault information is sent to an external device, which is convenient for maintenance personnel to quickly locate and solve the problem, reduce the system failure rate, and improve the reliability and maintainability of the system.

[0046] In the embodiment, by also performing statistics and analysis on the data of the first communication mode and the second communication mode, optimizing the parameters and application strategies of the two communication modes, and performing long-term statistical analysis on the communication data, it is possible to find which internal submodules have a large data transmission volume and high real-time requirements, and optimize the hardware configuration accordingly, so that limited communication resources can be more reasonably allocated and utilized, and communication efficiency can be improved. Load balancing and resource optimization can avoid the communication system being in a high-load state for a long time, and reduce the risk of hardware damage caused by excessive use. Through the optimized communication methods and strategies provided in the embodiment, it is possible to ensure that key data can be transmitted in a timely and accurate manner, reduce unnecessary delays, and facilitate the system to quickly make corresponding adjustments.
