[0027] The embodiments described in the following examples of this disclosure are not representative of 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.

[0028] It should be noted that the execution subject of the universal extension method compatible with multiple types of battery communication methods in this embodiment can be a universal extension device compatible with multiple types of battery communication methods, hereinafter referred to as "device". This device can be configured in any type of electronic device, and this application embodiment does not limit it.

[0029] See Figure 1FIG. 1 is a flowchart of a general expansion method compatible with multiple types of battery communication modes provided by the first embodiment of the present application. As shown in FIG. 1, the general expansion method compatible with multiple types of battery communication modes can include the following steps: Figure 1

[0030] Step 101, obtaining the newly added function execution data submitted by the operation and maintenance personnel.

[0031] The newly added function execution data refers to the key parameter data set used to instruct the battery to execute the newly added function according to the preset requirements (such as data format, parameter order, and value range) of the function after the operation and maintenance personnel selects the registered battery newly added function on the Web interface. It is the basis for the server to issue instructions to the battery.

[0032] Specifically, the operation and maintenance personnel opens the Web interface, selects the newly added function (such as “reservation heating”) to be executed for the battery from the list of registered functions, and fills in the details of the function to be executed according to the requirements of the function. For example, “reservation heating” requires filling in “heating duration” and “target temperature”, and filling in according to the specified format (such as using hexadecimal data to represent “0x000A” to represent 10 minutes). After the operation and maintenance personnel submits, the server receives the newly added function execution data.

[0033] Optionally, the input newly added function configuration information can be obtained and stored, wherein the newly added function configuration information at least includes: function name, and communication type corresponding communication identification information.

[0034] The function name is the unique identifier of the newly added function (such as “reservation heating”, “equalization charging start”, and “temperature threshold adjustment”), which is used for Web interface display, operation and maintenance personnel to select functions, and the server to distinguish between general functions and expansion functions.

[0035] If the communication type is RS485, the communication identification information is “network module instruction CID1 / CID2” (used for the battery to take instructions from the network module) and “battery feedback CID1 / CID2” (used for the battery to feedback the result to the network module), which is 4 bytes of data. If the communication type is CAN: the communication identification information is the sending frame ID (used for the network module to send instructions to the CAN bus) and the “reply frame ID” (used for the battery to feedback the result to the CAN bus), which is 8 bytes of data.

[0036] Specifically, the user can enter the above configuration information through the form of the Web interface, and after submission, the system first verifies the data legality (such as the function name is not repeated, and the communication identification information is in the correct format). After verification, the data is received, and if the verification fails, the user is prompted to correct. The configuration information that passes the verification is stored in the local database according to the fixed structure to form an association mapping table, which is convenient for subsequent server calls. ​

[0037] Step 102, in the case of judging that the added function is an expansion function, the added function execution data is encapsulated according to the communication type of the added function, and encapsulated data is obtained.

[0038] Among them, the added function can refer to the battery expansion function (such as preheating reservation, equalization charging start, etc.) registered by the Web interface configuration, which is not a system preset general function, needs to be adapted to a specific communication type and store the corresponding configuration parameters.

[0039] Among them, the expansion function is opposite to the system originally preset general function, which refers to the battery function added later through configuration, which needs to be implemented through a special instruction format, and its execution depends on the preset communication identification information and encapsulation rule.

[0040] Among them, the communication type refers to the communication protocol type of the terminal battery and the network module for data interaction, which specifically refers to RS485 communication or CAN communication in this scheme, which is the core basis for determining the data encapsulation format.

[0041] Among them, the added function execution data can be a set of key parameters entered by the operation and maintenance personnel after selecting the target expansion function on the Web interface, according to the format requirements (such as data type, byte length, parameter order) of the function preset, which is used to instruct the battery to execute the function.

[0042] Among them, the encapsulation can be the process of the server combining the added function execution data and the preset communication identification information (CID1 / CID2 or frame ID) associated with the communication type, and the communication type identification byte (0x01 / 0x02) according to the fixed format according to the communication type corresponding to the expansion function, forming standardized instruction data that can be correctly parsed by the network module and the battery.

[0043] Among them, the encapsulated data can be standardized instruction data formed through the above encapsulation process, which contains communication type identification, communication identification information, and added function execution data, can be recognized by the network module and forwarded to the target battery, and can be parsed by the battery to execute the corresponding expansion function.

[0044] Specifically, the server can query the local database, and if the current function is not in the preset general function list, it is determined as an expansion function.

[0045] It should be noted that different communication types of batteries need to add different communication identification information.

[0046] For example, the communication type is RS485, and the encapsulation format of the new function execution data is: 0x01 (RS485 identification byte) + network module instruction CID1 / CID2 (2 bytes) + battery reply CID1 / CID2 (2 bytes) + new function execution data. For example, if the communication identification information is instruction CID1=0x0A, CID2=0x0B, reply CID1=0x0C, CID2=0x0D, and the execution data is 0x1234 (representing the heating parameter), the encapsulated data is: 0x01 0x0A 0x0B 0x0C 0x0D 0x12 0x34.

[0047] For example, the communication type is CAN, and the encapsulation format is: 0x02 (CAN identification byte) + sending frame ID (4 bytes) + reply frame ID (4 bytes) + new function execution data. For example, if the communication identification information is sending frame ID=0x12345678, reply frame ID=0x87654321, and the execution data is 0x5678 (representing the heating parameter), the encapsulated data is: 0x02 0x12 0x34 0x56 0x78 0x87 0x65 0x43 0x21 0x56 0x78.

[0048] Step 103, based on the network module, processing the encapsulated data.

[0049] Optionally, based on the network module, it is judged whether the encapsulated data includes the control instruction corresponding to the new function. In the case that the encapsulated data includes the control instruction corresponding to the new function, the communication identification information contained in the encapsulated data is determined, then the flag bit corresponding to the communication type is set to the preset value based on the communication type corresponding to the communication identification information, then after the battery device obtains the encapsulated data and processes it, the processing result returned by the battery device is obtained, and then the processing result is returned to the server.

[0050] Among them, the flag bit is a binary bit or a specific byte in the network module, which is used to mark the communication type and the state of the instruction to be processed. By setting different values, the communication type and the signal that the instruction is to be executed are transmitted to the battery device.

[0051] Among them, the preset value is a predefined flag bit value, which is used to uniquely distinguish the communication type, and only contains two types of first preset value and second preset value, and corresponds to the communication type one by one.

[0052] Among them, the first identification information is the communication identification information of CAN communication, specifically "sending frame ID + reply frame ID" (a total of 8 bytes), which is the key basis for the network module to identify the CAN type extension instruction.

[0053] The second identification information is communication identification information of RS485 communication, specifically "network module instruction CID1 / CID2 + battery reply CID1 / CID2" (4 bytes in total), which is a key basis for the network module to identify RS485 type expansion instructions.

[0054] The first preset value is a flag bit preset value (such as 0x02) bound to CAN communication. After the battery device detects the value, it will obtain and parse the instruction from the network module according to the CAN communication protocol.

[0055] The second preset value is a flag bit preset value (such as 0x01) bound to RS485 communication. After the battery device detects the value, it will obtain and parse the instruction from the network module according to the RS485 communication protocol.

[0056] Different preset values represent different communication types. The battery device obtains the encapsulated data from the network module based on the control instruction and performs the corresponding operation under the condition of detecting the preset value.

[0057] Optionally, in the case of first identification information, if the communication type is determined to be CAN communication, the flag bit corresponding to the communication type is set to the first preset value. In the case of second identification information, if the communication type is determined to be RS485 communication, the flag bit corresponding to the communication type is set to the second preset value.

[0058] If the extracted communication identification information is the first identification information, it is determined that the communication type is CAN communication, and the corresponding flag bit is set to the first preset value. If the extracted communication identification information is the second identification information, it is determined that the communication type is RS485 communication, and the corresponding flag bit is set to the second preset value.

[0059] Specifically, the network module receives the encapsulated data sent by the server, and judges whether the control instruction corresponding to the new function is included. If it is confirmed that the new function control instruction is included, the communication identification information is parsed from the encapsulated data. According to the communication type corresponding to the communication identification information, the flag bit corresponding to the communication type in the network module is set to the preset value. After the battery device detects the preset value of the flag bit, it reads the encapsulated data from the network module, executes the corresponding operation according to the control instruction, and the network module obtains the processing result returned by the battery after processing. Finally, the result is fed back to the server.

[0060] Optionally, the processing result can be replied to the server through the expansion instruction channel.

[0061] Step 104, obtaining the processing result returned by the network module, and feeding back the processing result to the front end.

[0062] Specifically, the server receives the processing result uploaded by the network module (transmitted in the agreed encapsulation format) through the extended instruction channel, extracts the state information and data information in the result according to the analysis rule corresponding to the communication type, eliminates the redundant fields related to the communication protocol, converts the extracted information into a structured format that can be displayed by the front end, pushes the structured result to the Web front end through HTTP / WS and other protocols, and displays it on the specified interface (such as the function execution result page). Thus, the execution of the new function and the display of the result are completed.

[0063] In the embodiments of the present application, by adding the extended instruction, the batteries of multiple communication modes can be compatible after adding new functions, without modifying the network communication module each time, and the server software and the front end can complete the use of new functions; the extended instruction parameters of the new function are added through the Web, the extended instruction parameters of the new function are stored, and the channel function of the extended instruction is used to enable the server and the network module to recognize the added instruction data, correctly analyze the function and data, and correctly send them to the battery. After the battery is processed, the corresponding function processed data can also be correctly received and returned to the server, and the server can correctly analyze the corresponding data. Through the standardization of communication identification information and encapsulation rules, the batteries of multiple communication modes such as RS485 and CAN can share the same set of network module and server logic, and only need to configure parameters through the Web when adding new functions, without modifying the network module, server and front end code. Through the independent extended instruction channel and flag mechanism, the instruction conflict between the new function and the regular function is avoided, the data transmission stability is ensured, the operation personnel can complete the configuration and calling of the new function through the front end interface, and the operation threshold is reduced.

[0064] Figure 2 is the overall flowchart of the general expansion method compatible with multiple battery communication modes, which shows the link from Web configuration of new functions to result return to Web, and is divided into the left half (function configuration and instruction encapsulation) and the right half (network module processing and data return):

[0065] I. Left half: function configuration, instruction encapsulation and delivery

[0066] Web submission of new features: The operation and maintenance personnel enter the configuration information (such as function name, communication type, CID / frame ID, etc.) of the newly added function in the web interface, and these information is stored in the local database. Web reads the function list: The operation and maintenance personnel select the configured new function from the function list of the web, fill in the specific execution parameters (such as the duration and temperature of "preheat"), judge the communication type and encapsulate the instruction: If it is RS485 communication: The server adds identification byte 0x01 in front of the instruction, and takes out the corresponding "network module CID1 / CID2" and "battery reply CID1 / CID2" from the database, and splices them with the execution data filled by the operation and maintenance personnel to form a complete instruction. If it is CAN communication: The server adds identification byte 0x02 in front of the instruction, and takes out the corresponding "sending frame ID" and "reply frame ID" from the database, and splices them with the execution data filled by the operation and maintenance personnel to form a complete instruction. The instruction is sent to the network module: The server sends the encapsulated instruction to the network module.

[0067] II. Right half: Network module processing, battery execution and result return

[0068] The network module identifies the instruction type:

[0069] If it is a regular instruction: Process the data according to the original logic and return. If it is an extended instruction: Enter the special processing flow.

[0070] Execute the instruction according to the communication type:

[0071] RS485 scenario: The network module stores the instruction data with the flag bit 1 of CID1 / CID2, and the battery detects the flag bit and reads the instruction and executes the function, and then returns the result through the corresponding reply CID1 / CID2. CAN scenario: The network module sends the instruction to the CAN bus through the "sending frame ID", and listens to the "reply frame ID"; after the battery executes the function, it returns the result through the "reply frame ID". Result return server: The network module replaces the original instruction data with the result returned by the battery, and returns it to the server through the "extended instruction channel". Result return web: The server analyzes the data and returns the result to the web interface to display to the operation and maintenance personnel.
