[0032] The technical solutions of the present application and the technical solutions of the present application are described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. In the description of the present application, unless otherwise clearly specified and limited, each term should be understood in a broad sense in the art. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of the battery data transmission scenario provided by this application. Figure 1 As shown, the battery management system 100 transmits the battery status data to the terminal 120 .

[0034] The terminal 120 may be a communication device, such as a mobile terminal, a computer, a server, a tablet computer, a laptop computer, a smart watch, etc. The terminal 120 may also be a smart device, such as a drone, a cordless power tool, a robot, a robot dog, a sweeper, a cordless vacuum cleaner, etc. The terminal 120 may also be a transportation device, such as a pure electric vehicle, a hybrid vehicle, a fuel cell vehicle, an electric vehicle, an unmanned vehicle, etc.

[0035] In practical applications, according to the relevant requirements of the field, the battery management system 100 will periodically send information packets 110 to the terminal. Among them, the information packet 110 includes: a data frame header 111, data 112, and a check 113. The data frame header 111 represents the type identifier of the information packet, such as a voltage information packet identifier, a current information packet identifier, a temperature information packet identifier, a capacity information packet identifier, etc. The data 112 is real-time data corresponding to the information packet type, such as voltage real-time data, current real-time data, temperature real-time data, capacity real-time data, etc. The check 113 is used to protect the data 112 to avoid data distortion caused by the transmission process. Optionally, according to the requirements of the terminal 120, the periods of sending different types of information packets can be the same or different. For example, the battery management system 100 sends a current information packet to the terminal 120 every hour, and the battery management system 100 sends a capacity information packet to the terminal 120 every two hours. In practical applications, in order to ensure the normal operation of the terminal, the terminal needs to obtain the battery status from the battery management system in a timely manner, and the terminal sends a data request to the battery management system to request data transmission. In an embodiment of the present application, based on the terminal request, the battery management system is applied to periodically send information packets to the terminal, and the data requested by the terminal is mounted into the periodically sent information packets and transmitted to the terminal together, thereby enabling the battery management system to transmit data to the terminal in a timely and effective manner.

[0036] Embodiment 1

[0037] Figure 2 This is a flow chart of a battery data transmission method provided in the first embodiment of the present application. The implementation subject of this embodiment may be a battery data transmission device, such as Figure 2 As shown, the method includes:

[0038] S201, receiving a first transmission instruction sent by a terminal, where the first transmission instruction represents data to be transmitted;

[0039] S202, selecting a first extended information packet from the generated extended information packets according to the transmission period of the generated extended information packets;

[0040] S203, configuring the mount package identifier and the mount package in the first extended information package according to the data to be transmitted;

[0041] S204: When a transmission period of the first extended information packet arrives, send the configured first extended information packet to the terminal.

[0042] Among them, the first transmission instruction is an instruction for the terminal to request data to be transmitted, and the first transmission instruction represents the data to be transmitted. For example, the first transmission instruction may include: the address of the data to be transmitted; for example, the first transmission instruction includes address 1, and the data in address 1 is used as the data to be transmitted. For another example, the first transmission instruction may include: the type of data to be transmitted and the monitoring time. For example, the first transmission instruction includes: battery overvoltage data and 10:00:00. The battery overvoltage data at 10:00:00 is used as the data to be transmitted.

[0043] In practical applications, the execution subject of the battery data transmission method can be a battery data transmission device, which can be implemented in many ways, for example, it can be implemented through a computer program, such as application software, etc.; or, for example, a chip, etc. It can also be implemented as a medium storing relevant computer programs, such as a USB disk, a cloud disk, etc.; or, it can also be implemented through a physical device integrated or installed with relevant computer programs, such as a server, etc.

[0044] In order to better understand the solution, an example is given with reference to the structural diagram of the extended information packet. Figure 3 A schematic diagram of the structure of the extended information package provided in the first embodiment of the present application, such as Figure 3 As shown, the extended information packet includes: a basic information data packet header 301, basic information data 302, a basic check 303, a mount package identifier 304, a mount package 305 and a mount check 306. The basic information data packet header 301 represents the type of the extended information packet, which can be an extended information packet type identifier; the basic information data 302 is the real-time data corresponding to the extended information packet type. For example, the basic information packet data includes a voltage identifier, and the basic information data is voltage real-time data. The basic check 303 is used to protect the basic information data to prevent distortion during the transmission of the basic information data. The mount package identifier 304 represents whether data is encapsulated in the mount package; when the mount package identifier is empty, it means that there is no data in the current mount package; correspondingly, when the mount package identifier is not empty, it means that there is data in the mount package at this time. The mount package 305 can be used to encapsulate the data to be transmitted. The mount check 306 is used to protect the data to be transmitted to prevent distortion during the transmission of the data to be transmitted.

[0045] In actual applications, the basic information data packet header and basic information data of the generated extended information packet are not empty, and the identification and mounting package of the mount package are empty. Correspondingly, the basic information data packet header and basic information data of the unconfigured first extended information packet are not empty, and the identification and mounting package of the mount package are empty. After configuration, the data to be transmitted is encapsulated into the mount package.

[0046] Specifically, in S204, when the transmission cycle of the first extended information packet arrives, the configured first extended information packet is sent to the terminal. For example, the data to be transmitted is the battery overvoltage data at 10:10:00, and the first extended information packet is a current information packet. The configured first extended information packet includes: a current information packet identifier, current real-time data, the address of the battery overvoltage data at 10:10:00, and the battery overvoltage data at 10:10:00. When the transmission cycle of the first extended information packet arrives, the first extended information packet is sent to the terminal, and the terminal can obtain the voltage real-time data and the voltage overvoltage data at 10:10:00 at one time.

[0047] In this embodiment, based on the transmission request of the terminal, the data to be transmitted is encapsulated into the mounting package of the first extended information package, and the first extended information package is sent to the terminal, so that the battery management system can transmit data to the terminal in a timely and effective manner.

[0048] In addition, regarding the determination process of the first extended information packet, in one implementation, the S202 includes:

[0049] According to the transmission periods of the generated extended information packets, the extended information packet with the earliest transmission period among the generated extended information packets is used as the first extended information packet.

[0050] The transmission period of the extended information packet is the transmission period of the basic information data in the extended information packet, and the transmission periods corresponding to extended information packets of different basic data types are different. The first extended information packet is a special extended information packet for transmitting the data to be transmitted, and the transmission period of the first extended information packet is also determined according to the type of the basic information data.

[0051] Specifically, according to the transmission period of the generated extended information packets, the extended information packet with the earliest transmission period in the generated extended information packets is used as the first extended information packet. For example, assuming that the generated extended information packets include a voltage extended information packet and a current extended information packet, the transmission period of the voltage extended information packet is 30 seconds, and the transmission period of the current extended information packet is 15 seconds, it is found that the voltage extended information packet will start to be transmitted after 2 seconds from the current moment, and the current extended information will start to be transmitted after 10 seconds from the current moment, then the voltage extended information packet is selected as the first extended information packet.

[0052] It should be noted that when the mount packet in the extended information packet that arrives first in the transmission cycle has encapsulated other data to be transmitted, and the amount of data to be transmitted exceeds the remaining transmittable data amount of the mount packet, it is necessary to re-evaluate the extended information packet that arrives first in the transmission cycle. When the remaining transmittable data amount of the mount packet in the re-evaluated extended information packet can meet the data amount requirement of the data to be transmitted, the re-evaluated extended information packet will be used as the first extended information packet.

[0053] In this implementation, according to the transmission cycle of the extended information packets, the extended information packet with the earliest transmission cycle among the generated extended information packets is dynamically determined as the first extended information packet, so that the data to be transmitted can be transmitted to the terminal as quickly as possible, thereby improving the transmission efficiency of the data to be transmitted.

[0054] In addition, regarding the identification of the mount package and the configuration method of the mount package, in one embodiment, the S203 includes: obtaining the storage time of the data to be transmitted; and, in the order of storage time, encapsulating the data to be transmitted into the mount package in a one-way linked list; wherein each data to be transmitted in the mount package carries a pointer to the next data to be transmitted, and the pointer carried by the last data to be transmitted is empty; updating the identification of the mount package to a first pointer, and the first pointer points to the storage address of the first data to be transmitted in the mount package.

[0055] In actual applications, the data to be transmitted is stored in chronological order. According to the storage time of the data to be transmitted, the corresponding data to be transmitted in the storage space can be determined. For example, the battery management system monitors the battery status, stores the battery overvoltage data every 10 seconds, and stores the battery overvoltage data in the storage space corresponding to the battery management system in chronological order. If the data to be transmitted is the battery overvoltage data between 10:00:00 and 10:01:00, the battery management system extracts the battery overvoltage data between 10:00:00 and 10:01:00 from the storage space, and stores the data to be transmitted in the temporary cache in chronological order. For example, the data to be transmitted can be stored in the temporary cache in a stacked manner, with the battery overvoltage data at 10:00:00 at the bottom of the stack and the battery overvoltage data at 10:01:00 at the top of the stack.

[0056] Specifically, the data to be transmitted is encapsulated into the mount package in the order of storage time using a one-way linked list. For example, the data to be transmitted is the battery overvoltage data from 10:00:00 to 10:01:00, and the data to be transmitted is taken out from the temporary cache in sequence according to the time sequence and encapsulated into the mount package. For example, the data to be transmitted is stored in the temporary cache in a stack manner, and the battery overvoltage data at 10:00:00 is at the bottom of the stack, and the battery overvoltage data at 10:01:00 is at the top of the stack. In chronological order, the battery overvoltage data at 10:01:00 is taken out first and configured at the first position of the mount package, and the subsequent data is configured in sequence. There is a pointer behind each data, which points to the storage address of the next data, and the pointer behind the last data is empty.

[0057] Correspondingly, the identifier of the mount package is updated to a first pointer, and the first pointer points to the storage address of the first data to be transmitted in the mount package. For example, the first data in the mount package is the battery overvoltage data at 10:01:00, and the first pointer points to the storage address of the battery overvoltage data at 10:01:00.

[0058] In this implementation, the data to be transmitted is encapsulated into the mount package in a one-way linked list manner according to the storage time of the data to be transmitted, so that the terminal can obtain the data to be transmitted in time sequence, thereby improving the efficiency of data transmission.

[0059] In addition, considering the transmission of emergency data, in one implementation, the S204 further includes:

[0060] If there is urgent data currently, encapsulate the urgent data into the first position of the mount package encapsulating the data to be transmitted;

[0061] The data to be transmitted in the mount package is moved to after the urgent data, or the data to be transmitted in the mount package is deleted.

[0062] In practical applications, emergency data refers to data that the battery management system needs to transmit to the terminal urgently, and may be prompt data when the battery is abnormal, such as battery short circuit data, battery power data, etc.

[0063] Specifically, if there is urgent data currently, the urgent data is encapsulated into the first position of the mount package encapsulating the data to be transmitted. For example, if the current battery power is 10%, it may cause the terminal to automatically shut down. The battery management system needs to send the terminal the remaining battery power data, encapsulate the remaining battery power data into the first position of the extended package of the first extended information package to be transmitted, and update the mount package identifier to the storage address of the urgent data.

[0064] Correspondingly, the data to be transmitted in the mount package is moved to after the urgent data, or the data to be transmitted in the mount package is deleted. For example, the amount of data to be transmitted in the first extended information packet is small. After the urgent data is placed at the first position of the mount package, the data to be transmitted is retained, which has little impact on the transmission time of the first information extension packet. The data to be transmitted can be moved to after the urgent data. At this time, the pointer after the urgent data points to the storage address of the first data to be transmitted. For another example, the amount of data to be transmitted in the first extended information packet is large, and the time required for the transmission of the first information extension packet is long. After the urgent data is inserted into the first position of the mount package, the original data to be transmitted in the package is deleted, and only the urgent data is retained. At this time, the pointer after the urgent data is empty.

[0065] In this embodiment, if there is an urgent data transmission demand, the urgent data is inserted into the first position of the mount package, and according to the transmission status of the first information extension package, it is dynamically determined whether the data to be transmitted is retained. This can ensure that the urgent data is transmitted to the terminal in a timely manner, thereby improving the reliability and safety of the battery.

[0066] In addition, considering that the amount of data to be transmitted exceeds the preset transmittable amount of data of a single mount package, in one embodiment, the method further includes:

[0067] If the amount of the data to be transmitted exceeds the preset transmittable data amount of a single mount package, the data to be transmitted is split into a plurality of sub-data according to the transmittable data amount of the single mount package;

[0068] The S202 includes:

[0069] Selecting a plurality of first extended information packets having the same number as the plurality of sub-data from the generated extended information packets, wherein the plurality of first extended information packets correspond to the plurality of sub-data in a one-to-one manner;

[0070] The S203 includes:

[0071] According to the data to be transmitted, the identifier of the mount package and the mount package in the first extended information package are configured, wherein the identifier of the configured mount package represents the storage location of the sub-data corresponding to the first extended information package, and the configured mount package encapsulates the sub-data corresponding to the first extended information package.

[0072] In practical applications, in order to ensure the efficiency of data transmission between the battery and the terminal, the amount of data that can be transmitted by a single mounted package can be set. For example, the amount of data that can be transmitted by a single mounted package is 5. Specifically, if the amount of data to be transmitted exceeds the preset amount of data that can be transmitted by a single mounted package, the data to be transmitted is split into multiple sub-data according to the amount of data that can be transmitted by the single mounted package. For example, if the amount of data to be transmitted is 20, the data to be transmitted can be divided into sub-data 1, sub-data 2, sub-data 3 and sub-data 4 in chronological order.

[0073] Correspondingly, from the generated extended information packets, multiple first extended information packets are selected that are consistent with the number of the multiple sub-data, and the multiple first extended information packets correspond to the multiple sub-data one by one. For example, the number of sub-data is 4, and the four first extended information packets are selected, namely: first extended information packet 1, first extended information packet 2, first extended information packet 3, and first extended information packet 4. First extended information packet 1 is used to transmit sub-data 1, first extended information packet 2 is used to transmit sub-data 2, first extended information packet 3 is used to transmit sub-data 3, and first extended information packet 4 is used to transmit sub-data 4.

[0074] Correspondingly, according to the data to be transmitted, the identifier of the mount package and the mount package in the first extended information package are configured, wherein the identifier of the configured mount package represents the storage location of the sub-data corresponding to the first extended information package, and the configured mount package encapsulates the sub-data corresponding to the first extended information package. For example, the mount package identifier in the configured first information extension package 1 represents the storage address of the first data of sub-data 1, and the mount package encapsulates sub-data 1; the mount package identifier in the configured first information extension package 2 represents the storage address of the first data of sub-data 2, and the mount package encapsulates sub-data 2; the mount package identifier in the configured first information extension package 3 represents the storage address of the first data of sub-data 3, and the mount package encapsulates sub-data 3; the mount package identifier in the configured first information extension package 4 represents the storage address of the first data of sub-data 4, and the mount package encapsulates sub-data 4.

[0075] In this embodiment, when the amount of data to be transmitted exceeds the preset transmittable data amount of a single mount package, the data to be transmitted is split into multiple sub-data, and a corresponding number of first extended information packets are used to transmit the data to be transmitted, thereby improving the transmission efficiency of the data to be transmitted.

[0076] In addition, for the transmission process of the extended information packet that is not selected to transmit the data to be transmitted, in one embodiment, the method also includes: for the second extended information packet other than the first extended information packet in the generated extended information packet, based on the transmission period of the second extended information packet, sending the second extended information packet to the terminal.

[0077] The second extended information packet is an extended information packet that is not selected to transmit the data to be transmitted, and is only used to transmit basic information data. The mount package identifier and the mount package are empty. In actual applications, if the first transmission instruction is not received, all the generated extended information packets are second extended information packets, which are only used to transmit basic information data; or, if the first transmission instruction is received and the extended information packet that is not selected as the first extended information packet is used as the second extended information packet, which is only used to transmit basic information data.

[0078] In actual applications, when the transmission cycle of the extended information packet arrives, the extended information packet is sent to the terminal. Specifically, based on the transmission cycle of the second extended information packet, the second extended information packet is sent to the terminal. For example, the transmission cycle of the battery capacity extended information packet is 30 seconds. According to the transmission cycle, it is determined that the next battery capacity extended information packet will be transmitted in 10 seconds. Before the transmission cycle arrives, the battery capacity extended information packet is not selected to transmit the data to be transmitted. In this case, the battery capacity extended information packet is used as the second extended information packet, and when the transmission cycle arrives, the second extended information packet is transmitted to the terminal.

[0079] In this embodiment, when the second extended information packet transmission period arrives, the second extended information packet is transmitted to the terminal, thereby ensuring the transmission of basic information data and providing reliable and secure data for the terminal.

[0080] In the battery data transmission method provided in this embodiment, a first transmission instruction sent by a receiving terminal represents the data to be transmitted; according to the transmission cycle of the generated extended information packet, a first extended information packet is selected from the generated extended information packet; according to the data to be transmitted, the identifier and the mounted package in the first extended information packet are configured; when the transmission cycle of the first extended information packet arrives, the configured first extended information packet is sent to the terminal. In the battery data transmission process of this embodiment, based on the request of the terminal, the data to be transmitted required by the terminal is configured into the mounted package in the first extended information packet with a fixed transmission cycle, and the data to be transmitted is transmitted to the terminal through the first extended information packet, so that the battery management system can transmit data to the terminal in a timely and effective manner.

[0081] Embodiment 2

[0082] Figure 4 This is a schematic diagram of the structure of the battery data transmission device provided in the second embodiment of the present application. Figure 4 As shown, the device comprises:

[0083] A receiving module 41, configured to receive a first transmission instruction sent by a terminal, wherein the first transmission instruction represents data to be transmitted;

[0084] A selection module 42, configured to select a first extended information packet from the generated extended information packets according to the transmission period of the generated extended information packets;

[0085] A configuration module 43, configured to configure the mount package identifier and the mount package in the first extended information package according to the data to be transmitted;

[0086] The sending module 44 is configured to send the configured first extended information packet to the terminal when the transmission period of the first extended information packet arrives.

[0087] The first transmission instruction is an instruction for the terminal to request the data to be transmitted, and the first transmission instruction represents the data to be transmitted.

[0088] In actual applications, the basic information data packet header and basic information data of the generated extended information packet are not empty, and the identification and mounting package of the mount package are empty. Correspondingly, the basic information data packet header and basic information data of the unconfigured first extended information packet are not empty, and the identification and mounting package of the mount package are empty. After configuration, the data to be transmitted is encapsulated into the mount package.

[0089] In this embodiment, based on the transmission request of the terminal, the data to be transmitted is encapsulated into the mounting package of the first extended information package and sent to the terminal through the first extended information package, thereby realizing timely and effective data transmission from the battery management system to the terminal.

[0090] In addition, in one embodiment, the selection module 42 is specifically used for:

[0091] According to the transmission periods of the generated extended information packets, the extended information packet with the earliest transmission period among the generated extended information packets is used as the first extended information packet.

[0092] The transmission period of the extended information packet is the transmission period of the basic information data in the extended information packet, and the transmission periods corresponding to extended information packets of different basic data types are different. The first extended information packet is a special extended information packet for transmitting the data to be transmitted, and the transmission period of the first extended information packet is also determined according to the type of the basic information data.

[0093] It should be noted that when other data to be transmitted have been encapsulated in the mount packet in the extended information packet that arrives first in the transmission cycle, and the amount of data to be transmitted exceeds the remaining transmittable data amount of the mount packet, it is necessary to re-evaluate the extended information packet that arrives first in the transmission cycle. When the remaining transmittable data amount of the mount packet in the re-evaluated extended information packet can meet the data amount requirement of the data to be transmitted, the re-evaluated extended information packet is used as the first extended information packet. In this embodiment, according to the transmission cycle of the extended information packet, the extended information packet that arrives first in the transmission cycle among the generated extended information packets is dynamically determined as the first extended information packet, so that the data to be transmitted can be transmitted to the terminal as quickly as possible, thereby improving the transmission efficiency of the data to be transmitted.

[0094] In addition, in one embodiment, the configuration module 43 includes:

[0095] An encapsulation unit is used to obtain the storage time of the data to be transmitted; and, in the order of the storage time, the data to be transmitted is encapsulated into the mount package in a one-way linked list; wherein each data to be transmitted in the mount package carries a pointer to the next data to be transmitted, and the pointer carried by the last data to be transmitted is empty; an update unit is used to update the identifier of the mount package to a first pointer, and the first pointer points to the storage address of the first data to be transmitted in the mount package.

[0096] In practical applications, the data to be transmitted are stored in chronological order. According to the storage time of the data to be transmitted, the corresponding data to be transmitted in the storage space can be determined.

[0097] In this implementation, the data to be transmitted is encapsulated into the mount package in a one-way linked list manner according to the storage time of the data to be transmitted, so that the terminal can obtain the data to be transmitted in time sequence, thereby improving the efficiency of data transmission.

[0098] In addition, in one implementation, the configuration module 43 further includes:

[0099] an inserting unit, configured to encapsulate the urgent data into the first position of the mount package encapsulating the data to be transmitted if there is urgent data currently;

[0100] The processing unit is used to move the data to be transmitted in the mount package to after the urgent data, or to delete the data to be transmitted in the mount package.

[0101] In practical applications, emergency data refers to data that the battery management system needs to transmit to the terminal urgently, and may be prompt data when the battery is abnormal.

[0102] In this embodiment, if there is an urgent data transmission demand, the urgent data is inserted into the first position of the mount package, and according to the transmission status of the first information extension package, it is dynamically determined whether the data to be transmitted is retained. This can ensure that the urgent data is transmitted to the terminal in a timely manner, thereby improving the reliability and safety of the battery.

[0103] In addition, in one embodiment, the device further comprises:

[0104] A splitting module, configured to split the data to be transmitted into a plurality of sub-data according to the transmittable data volume of the single mount package if the data volume of the data to be transmitted exceeds the transmittable data volume of the preset single mount package;

[0105] The selection module 42 is specifically used for:

[0106] Selecting a plurality of first extended information packets having the same number as the plurality of sub-data from the generated extended information packets, wherein the plurality of first extended information packets correspond to the plurality of sub-data in a one-to-one manner;

[0107] The configuration module 43 is specifically used for:

[0108] According to the data to be transmitted, the identifier of the mount package and the mount package in the first extended information package are configured, wherein the identifier of the configured mount package represents the storage location of the sub-data corresponding to the first extended information package, and the configured mount package encapsulates the sub-data corresponding to the first extended information package.

[0109] In practical applications, in order to ensure the efficiency of data transmission between the battery and the terminal, the amount of data that can be transmitted by a single mount package can be set.

[0110] In this embodiment, when the amount of data to be transmitted exceeds the preset transmittable data amount of a single mount package, the data to be transmitted is split into multiple sub-data, and a corresponding number of first extended information packets are used to transmit the data to be transmitted, thereby improving the transmission efficiency of the data to be transmitted.

[0111] In addition, in one implementation, the sending module is further configured to: for a second extended information packet other than the first extended information packet in the generated extended information packets, send the second extended information packet to the terminal based on a transmission period of the second extended information packet.

[0112] Among them, the second extended information packet is an extended information packet that is not selected to transmit the data to be transmitted, and is only used to transmit basic information data. The mount package identifier and the mount package are empty. In actual applications, if the first transmission instruction is not received, all the generated extended information packets are second extended information packets, which are only used to transmit basic information data; or, if the first transmission instruction is received and the extended information packet is not selected as the first extended information packet, it is used as the second extended information packet, which is only used to transmit basic information data. In actual applications, when the transmission period of the extended information packet arrives, the extended information packet is sent to the terminal.

[0113] In this embodiment, when the second extended information packet transmission period arrives, the second extended information packet is transmitted to the terminal, thereby ensuring the transmission of basic information data and providing reliable and secure data for the terminal.

[0114] In the battery data transmission device provided in this embodiment, the receiving module receives the first transmission instruction sent by the terminal, and the first transmission instruction represents the data to be transmitted; the selection module selects the first extended information packet from the generated extended information packet according to the transmission cycle of the generated extended information packet; the configuration module configures the identifier and the mounted package in the first extended information packet according to the data to be transmitted; when the transmission cycle of the first extended information packet arrives, the sending module sends the configured first extended information packet to the terminal. In the battery data transmission process of this embodiment, based on the request of the terminal, the data to be transmitted required by the terminal is configured into the mounted package in the first extended information packet with a fixed transmission cycle, and the data to be transmitted is transmitted to the terminal through the first extended information packet, so that the battery management system can transmit data to the terminal in a timely and effective manner.
