Description

Technical Field

[0001] The present invention relates to the technical field of battery cell parameter management, and in particular to a method, device, equipment and readable storage medium for sending battery cell parameters. Background Art

[0002] The battery management system BMS (Battery Management System) can collect battery cell parameters through the AFE (Active Front End) chip. Users or testers need to use the CAN bus network to observe whether the collected battery cell parameters are normal.

[0003] Generally speaking, each battery pack consists of about 100-200 cells. An AFE chip has multiple sampling channels. One sampling channel in the AFE chip can collect one cell parameter, so there are a lot of cell parameters to be collected. When outputting these data through the CAN bus network, it is necessary to configure a CAN message for each cell parameter and map each cell parameter to the corresponding CAN message.

[0004] The above mapping process is now mostly done manually. If the number of AFE chips and the number of cell parameters collected by the AFE chips do not change, the operation can be performed once. However, when the project changes, that is, when the number of AFE chips changes or the number of cell parameters collected by the AFE chips changes, the mapping between the corresponding cell parameters and CAN messages must also be modified, resulting in repeated and cumbersome operations. Summary of the invention

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0041] An embodiment of the present invention provides a method for sending battery cell parameters, which can solve the technical problem that in the existing process of sending battery cell parameters through CAN messages, whenever the number of AFE chips changes or the number of battery cell parameters collected by each AFE chip changes, each battery cell parameter needs to be manually re-mapped with the CAN message one by one, and the operation is repetitive and cumbersome.

[0042] See also Figure 1 As shown, an embodiment of the present invention provides a method for sending battery cell parameters, comprising the following steps:

[0043] Step S10, obtaining all cell parameters collected by all AFE chips.

[0044] Wherein, the battery cell parameters include voltage parameters and temperature parameters.

[0045] Step S20, determining the message ID number corresponding to each cell parameter to be sent according to the preset configuration file and the number of cell parameters that can be filled in each CAN message;

[0046] The preset configuration file includes the serial number of each AFE chip and the number of battery cell parameters collected by each AFE chip.

[0047] Specifically, see Figure 2 As shown, the step of determining the message ID number corresponding to each cell parameter according to the preset configuration file and the number of cell parameters that can be filled in each CAN message includes:

[0048] Step S201, constructing a two-dimensional table including the AFE chip number and the corresponding message ID number according to the preset configuration file and the number of battery cell parameters that can be filled in each CAN message;

[0049] Assume that there are three AFE chips, namely AFE1, AFE2, and AFE3, the number of battery cell parameters collected by AFE1 is 16, the number of battery cell parameters collected by AFE2 is 20, and the number of battery cell parameters collected by AFE3 is 24, then the preset configuration file is shown in Table 1.

[0050] Table 1

[0051] AFE chip serial number Number of cell parameters 1 16 2 20 3 24

[0052] Further, see Figure 3 As shown, the step of constructing a two-dimensional table including the AFE chip number and the corresponding message ID number according to the preset configuration file and the number of battery cell parameters that can be filled in each CAN message includes:

[0053] Step S2011, determining the message ID sequence number of the CAN message used to send the AFE chip to collect the cell parameters according to the number of cell parameters collected by each AFE chip and the number of cell parameters that can be filled in each CAN message.

[0054] Among them, if the number of battery cell parameters collected by each AFE chip is an integer multiple N of the battery cell parameters that can be filled in each CAN message, M_1~M_N are used as the message ID serial numbers of the CAN messages used to send the AFE chip to collect the battery cell parameters; among them, M is the AFE chip serial number.

[0055] If the number of battery cell parameters collected by each AFE chip is a multiple N of the battery cell parameters that can be filled in each CAN message and there is a remainder, M_1 to M_N+1 are used as the message ID sequence numbers of the CAN messages used to send the AFE chip to collect the battery cell parameters.

[0056] Step S2012: construct a two-dimensional table according to the serial number of each AFE chip and the message ID serial number corresponding to the AFE chip.

[0057] Specifically, assuming that the number of battery cell parameters that can be filled in each CAN message is 4, for the AFE1 chip, 4 messages are needed to send the 16 battery cell parameters collected by the AFE1 chip, then the message ID serial numbers of the CAN messages used to send the AFE1 chip to collect battery cell parameters are determined to be message ID1_1, message ID1_2, message ID1_3, and message ID1_4. Similarly, the message ID serial numbers of the CAN messages used to send the AFE2 chip to collect battery cell parameters are determined to be message ID2_1, message ID2_2, message ID2_3, message ID2_4, and message ID2_5. The message ID serial numbers of the CAN messages used to send the AFE3 chip to collect battery cell parameters are determined to be message ID3_1, message ID3_2, message ID3_3, message ID3_4, message ID3_5, and message ID3_6. The specific two-dimensional number table is shown in Table 2 below. It should be noted that if AFE1 collects 17 battery cell parameters, the message ID number of the CAN message sent by the AFE1 chip to collect the battery cell parameters is increased by message ID1_5, and the CAN message corresponding to message ID1_5 only sends the 17th battery cell parameter collected by the AFE1 chip.

[0058] Table 2

[0059]

[0060] Step S202, determining the message ID number for sending each battery cell parameter according to the preset configuration file and the constructed two-dimensional table.

[0061] Specifically, see Figure 4As shown, the step of determining the message ID number for sending each battery cell parameter according to the preset configuration file and the constructed two-dimensional table includes:

[0062] Step S2021, traverse all the battery cell parameters collected by all AFE chips, and perform self-increment counts. Through two nested loops, all the battery cell parameters collected by all AFE chips can be traversed. As assumed above, 3 AFE chips collect 60 battery cell parameters. According to the serial number of the AFE chip in the preset configuration file and the number of battery cell parameters collected by each AFE chip, the battery cell parameter pointed to by the count value index in the loop traversal belongs to which AFE chip and which battery cell parameter. For example, the count value index is 18, and it can be located that the count value 18 corresponds to the second battery cell parameter of the AFE2 chip.

[0063] Step S2022, determining the message ID number of each battery cell parameter according to the count value and the constructed two-dimensional table.

[0064] Continuing with the above assumptions, the count value index is 18, and the positioning count value 18 corresponds to the second battery cell parameter of the AFE2 chip. According to the constructed two-dimensional table, the second battery cell parameter of the AFE2 chip corresponds to the message ID number of message ID2_1. In other words, when the count value index is 17 to 20, it corresponds to the 1st to 4th battery cell parameters of the AFE2 chip, and the message ID number for sending the 1st to 4th battery cell parameters of the AFE2 chip is message ID2_1.

[0065] Step S30, filling each cell parameter into the CAN message corresponding to the message ID number and sending it to the CAN bus network.

[0066] Based on the above content, when determining the message ID number corresponding to each battery cell parameter, fill each battery cell parameter and the corresponding message ID number into the CAN message, and upload the CAN message to the CAN bus network after forming the CAN message, so that the devices on the CAN bus network can obtain all battery cell parameters collected by all AFE chips, so that users or testers can observe whether the collected battery cell parameters are normal through the CAN network.

[0067] In particular, when a project changes (the number of AFE chips changes or the number of battery cell parameters collected by each AFE chip changes), it is only necessary to know the serial number of the AFE chip and the number of battery cell parameters collected by each AFE chip in the changed project configuration, and then modify the corresponding preset configuration file in the implementation of the present invention. According to the configuration quantity in the preset configuration file, it is possible to automatically fill the battery cells collected by the corresponding AFE chip into the corresponding CAN message. That is, each time the project changes, it is only necessary to modify a few configuration quantities in the preset configuration file (the serial number of the AFE chip and the number of battery cell parameters collected by each AFE chip) to automatically complete the mapping and filling of the CAN message and the battery cell parameters collected by the AFE chip.

[0068] For example, assuming that the number of AFE chips increases to 4 (AFE4 is added), and the number of cell parameters collected by the AFE1 chip becomes 20, the number of cell parameters collected by the AFE2 chip becomes 24, the number of cell parameters collected by the AFE3 chip becomes 20, and the number of cell parameters collected by the AFE4 chip is 16, the corresponding preset configuration files are shown in Table 3.

[0069] Table 3

[0070] AFE chip serial number Number of cell parameters 1 20 2 24 3 20 4 16

[0071] Correspondingly, a two-dimensional table is constructed according to the serial number of each AFE chip and the message ID serial number corresponding to the AFE chip as shown in Table 4. According to the two-dimensional table, the message ID serial number filled with each battery cell parameter can be quickly determined, which is more efficient than the prior art of manually re-mapping each battery cell parameter with the CAN message one by one.

[0072] Table 4

[0073]

[0074] The method for sending cell parameters in the embodiment of the present invention determines the message ID number corresponding to each cell parameter to be sent according to a preset configuration file including the serial number of each AFE chip and the number of cell parameters collected by each AFE chip, and then fills all the acquired cell parameters into the corresponding CAN message based on the message ID number, thereby realizing automatic mapping and filling of cell parameters and CAN messages. After the project is modified, it is only necessary to modify the configuration amount in the preset configuration file to quickly re-establish the mapping relationship, thereby improving the efficiency of sending cell parameters.

[0075] As an optional implementation manner, in an embodiment of the invention, the step of determining the message ID sequence number of the CAN message used to send the AFE chip to collect the cell parameters according to the number of cell parameters collected by each AFE chip and the number of cell parameters that can be filled in each CAN message includes:

[0076] First, M_1 is used as the first message ID number of the CAN message used to send the AFE chip to collect battery cell parameters, and the remaining message ID numbers are increased one by one according to the quantity required for the AFE chip to collect battery cell parameters.

[0077] Specifically, as shown in Table 5, M_1 may be used as the first message ID number of the CAN message for sending the AFE chip to collect the cell parameters, and then the message ID numbers may be increased one by one according to the quantity of the cell parameters collected by the AFE chip.

[0078] For example, if the AFE1 chip collects 4 battery cell parameters, message ID1_1 can meet the requirements. If the AFE2 chip collects 8 battery cell parameters, message ID2_1 does not meet the requirements. A message ID number (ID2_2) is added as needed to save data storage space as much as possible.

[0083] The acquisition unit is used to acquire all cell parameters collected by all AFE chips.

[0084] The determination unit is used to determine the message ID serial number corresponding to each battery cell parameter to be sent according to a preset configuration file and the number of battery cell parameters that can be filled in each CAN message; wherein the preset configuration file includes the serial number of each AFE chip and the number of battery cell parameters collected by each AFE chip.

[0085] The sending unit is used to fill each battery cell parameter into the CAN message corresponding to the message ID number and send it to the CAN bus network.

[0086] The battery cell parameter sending device in the embodiment of the present invention determines the message ID number corresponding to each battery cell parameter to be sent according to a preset configuration file including the serial number of each AFE chip and the number of battery cell parameters collected by each AFE chip, and then fills all the acquired battery cell parameters into the corresponding CAN message based on the message ID number, thereby realizing automatic mapping and filling of battery cell parameters and CAN messages. After the project is modified, it is only necessary to modify the configuration amount in the preset configuration file to quickly re-establish the mapping relationship, thereby improving the efficiency of battery cell parameter sending.
