Description

Battery coding method, device, electronic device and battery Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery coding method, device, electronic device, and battery. Background Art

[0002] Batteries are typically assembled from multiple cells. To better manage the battery, they are typically equipped with a Battery Management Unit (BMU), which serves as the master controller for the entire battery. To better manage the battery, the BMU typically monitors each cell and obtains its operating parameters.

[0003] Currently, the battery management unit (BMU) typically uses a wired connection to a data collector that collects data from individual battery cells to obtain the parameters collected by the collector. However, if each collector collects the parameters of a single battery cell, a large number of wires must be built into the battery plant, making factory operations complex and inefficient. If the data collector has a one-to-many relationship with each battery cell, communication between the BMU and the individual battery cells may be hindered, potentially limiting the accuracy of individual battery cell management.

[0049] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0050] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0051] In order to better manage the battery, it is usually necessary to obtain the operating parameters of each battery cell in the battery from time to time, such as the temperature, current, voltage and other parameters of the battery cell, so as to better manage the battery and monitor the battery safety.

[0052] The inventors have discovered that the current management of each battery cell in a battery is achieved by pre-installing sensors at various locations within the battery, which collect the operating parameters of several surrounding battery cells. Each sensor can then be connected to the battery management unit (BMU) of the battery, allowing the BMU to obtain the data collected by the sensors. Generally, if there are fewer sensors in a battery, the wiring required to connect the sensors to the BMU is relatively simple, making operation easier. However, this inevitably results in an inability to accurately locate the status of each battery cell. If more sensors are deployed in the battery, for example, each battery cell is equipped with one or more sensors, the data collected by the sensors can be better aligned with the battery cells, allowing for accurate location of the status of each battery cell. However, this inevitably results in a relatively complex wiring connection between the sensors and the BMU, making factory line operation complex and wiring efficiency low.

[0053] Based on the above analysis, the present application provides a battery encoding method, device, electronic device, and battery. By associating the chip identification information corresponding to each battery cell with the location of each battery cell and storing it in the battery's battery management unit, one-to-one communication between the battery management unit and the chip of each battery cell can be achieved without the need for a large number of wire connections in the battery. The battery encoding method, device, electronic device, and battery provided by the present application are described below through some embodiments.

[0054] First, the terms involved in the embodiments of this application are explained:

[0055] Intelligent battery cell: iCell, refers to a battery cell that integrates a cell monitoring unit (CMU);

[0056] Cell Monitoring Unit (CMU): This unit integrates a dedicated chip that integrates analog front-end (AFE), microcontroller unit (MCU), and wireless communication (Radio Frequency, RF) functions.

[0057] The Radio Management Unit (RMU) is responsible for managing the entire wireless network, communicating with the CMUs of all smart battery cells, receiving voltage and temperature data collected by all CMUs, and sending corresponding control instructions to the Host MCU;

[0058] Host MCU (Host_MCU), used to control the communication between RMU and CMU, complete data processing and analysis and output control instructions;

[0059] Battery Management Unit (BMU), the main controller for the entire battery management;

[0060] A battery module is a power supply unit that can include multiple smart battery cells;

[0061] A battery is a power supply unit that can include multiple smart battery cells or multiple battery modules.

[0062] The batteries and battery cells disclosed in the embodiments of this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. A power supply system comprising the battery cells and batteries disclosed in this application can be used to form the electrical device.

[0063] As shown in Figure 1 , the battery 100 provided in this embodiment may include: a battery management unit 110, a plurality of battery cells 120, and a cell monitoring unit 130 (only a portion of which is shown) mounted on each battery cell 120. In actual use scenarios, a cell monitoring unit 130 may be provided on each battery cell 120.

[0064] The battery management unit 110 records the chip identification information and the location information of each battery cell 120. Optionally, the location identification can be presented in the form of coordinates or numerical values.

[0065] For example, the position identifier can be represented by coordinates, which can indicate the row and column position of the battery cell 120. For another example, the position identifier can be represented by a numerical value, which can indicate the position according to a set order.

[0066] The cell monitoring unit 130 stores the chip identification information and location information of each battery cell 120. When the battery management unit 110 needs to obtain the operating parameters of each battery cell 120, it can communicate with each cell monitoring unit 130 to obtain the operating parameters of the battery cell 120 collected by each cell monitoring unit 130. These operating parameters may include the operating temperature, voltage, current, and other parameters of the battery cell 120.

[0067] Optionally, the cell monitoring unit 130 may write the battery cell 120 location identifier consistent with its chip identification information into its memory, and the location identifier stored in the memory may be protected. The memory may be a type of memory of a single-chip microcomputer (One Time Programmable, OTP), a read-only memory (ROM), a flash memory (Flash EEPROM), or other memory.

[0068] Optionally, the battery of this embodiment may also be composed of multiple battery modules, and each battery module may include multiple battery cells 120.

[0069] Each battery module is provided with a module identification, which records chip identification information of each battery cell 120 in the battery module and first position information of each battery cell 120 in the battery module.

[0070] The battery management unit 110 records the second position information of each battery module in the battery.

[0071] For example, the second position information may be represented by only a numerical value, for example, the numerical value may represent the position sequence of the corresponding battery module in the battery. For example, if a battery includes five battery modules, the numerical value representing the second position information may be any value between 1 and 5.

[0072] The first position information may be represented by a numerical value, a pair of numerical values, or a coordinate.

[0073] For example, the first position information may be represented by a numerical value, which is used to represent the position sequence of the battery cell 120 in the battery module. For example, if the battery module includes seven rows and eight columns of battery cells 120, the numerical value may be any value between 1 and 56.

[0074] For another example, a pair of numbers may include a first numerical value and a second numerical value, wherein the first numerical value is used to indicate the position sequence of the battery module in which the battery cell 120 is located in the battery. For example, a battery includes three battery modules, and the value of the first numerical value may be any number from one to three; the second numerical value is used to indicate the position sequence of the battery cell 120 in the battery module. For example, the battery module includes seven rows and eight columns of battery cells 120, and the value of the second numerical value may be any number from one to fifty-six.

[0075] In one example, the battery cells in the battery 100 may be arranged in sequence in the direction of the dotted arrows shown in FIG. 1 .

[0076] For another example, the coordinates may include battery module sequence coordinates and battery cell 120 sequence coordinates, wherein the battery module sequence coordinates represent the sequence of the battery module where the battery cell 120 is located in the battery, and the battery cell 120 sequence coordinates may represent the sequence of the battery cell 120 in the battery module.

[0077] The battery management unit 110 in the battery of this embodiment may further include a wireless management unit and a main control MCU (not shown).

[0078] The wireless management unit can be used to manage the entire wireless network, communicate with the cell monitoring units 130 of all battery cells 120, receive voltage, temperature data, current and other parameters of the battery cells 120 collected by all cell monitoring units 130, and send corresponding control instructions to the Host MCU.

[0079] The main control MCU is used to control the communication between the wireless management unit and the battery cell monitoring unit 130, and complete data processing and analysis and the output of control instructions.

[0080] As shown in FIG. 1 , the battery 100 may be a battery pack, which may further include a box 140 , in which the battery cells 120 may be installed.

[0081] The battery 100 may also be a battery module, which includes a plurality of battery cells, and the battery cells may be arranged as needed.

[0082] The present application provides an electrical device using the above-mentioned battery as a power source. The electrical device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, etc. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0083] The battery encoding method described above can be used to process the battery so that the battery management unit of the battery can store the information of each battery cell, thereby facilitating communication between the battery management unit and the cell monitoring unit of each battery cell. To facilitate understanding of this embodiment, the operating environment of the battery encoding method disclosed in the embodiment of this application is first introduced.

[0084] FIG2 is a schematic diagram illustrating the interaction between a host computer 210 and a scanning device 220 according to an embodiment of the present application. The host computer 210 communicates with one or more scanning devices 220 via a network or wired connection for data communication or interaction. The host computer 210 may be a network server, a database server, or a personal computer (PC), a tablet computer, a smartphone, or a personal digital assistant (PDA).

[0085] For example, the host computer 210 and the scanning device 220 may be arranged in a battery production workshop. The host computer 210 may be used to send control instructions to various devices in the production workshop, and the host computer 210 may also obtain operating parameters of various devices in the production workshop.

[0086] In this embodiment, the scanning device 220 can be placed at various locations in the production workshop to scan the identification set on the battery cells or battery modules at different stages of battery production. The identification can be presented in the form of a string, a QR code, a barcode, etc.

[0087] In one example, each identifier may be a QR code, and the scanning device 220 may be a QR code scanner.

[0088] In this embodiment, the host computer 210 may be an electronic device having storage and processing functions. FIG3 is a block diagram of an electronic device. The electronic device 300 may include a memory 311 and a processor 313. Those skilled in the art will appreciate that the structure shown in FIG3 is merely illustrative and does not limit the structure of the electronic device 300. For example, the electronic device 300 may include more or fewer components than shown in FIG3 , or may have a configuration different from that shown in FIG3 .

[0089] The memory 311 and processor 313 are electrically connected to each other, directly or indirectly, to enable data transmission or interaction. For example, these components may be electrically connected to each other via one or more communication buses or signal lines. The processor 313 is used to execute the executable modules stored in the memory.

[0090] The memory 311 may be, but is not limited to, a random access memory (RAM), a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), etc. The memory 311 is used to store a program, and the processor 313 executes the program after receiving an execution instruction. The method executed by the electronic device 300 defined by the process disclosed in any embodiment of the present application can be applied to the processor 313 or implemented by the processor 313.

[0091] The processor 313 may be an integrated circuit chip with signal processing capabilities. The processor 313 may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it may also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. The various methods, steps, and logic block diagrams disclosed in the embodiments of the present application may be implemented or executed. The general-purpose processor may be a microprocessor or any conventional processor.

[0092] The electronic device 300 in this embodiment can be used to execute each step in each method provided in the embodiments of the present application. The implementation process of the battery encoding method is described below through several embodiments.

[0093] Please refer to Figure 4, which is a flow chart of the battery encoding method provided in an embodiment of the present application. The battery encoding method of this embodiment can be executed by the host computer shown in Figure 2 above, or by a system including a host computer and a scanning device. The specific process shown in Figure 4 will be described in detail below.

[0094] Step 410: Acquire location information of battery cells in the battery.

[0095] Optionally, the starting position of the battery can be determined first. This starting position can be the battery cell at the outermost edge of the battery. For example, if the battery includes M rows and N columns of battery cells, the starting position can be the battery cell in the first row and first column. Then, from this starting position, the position information of each battery cell in the battery is determined sequentially according to the arrangement of the battery cells in the battery.

[0096] For example, the battery may be identified by image recognition to determine the starting position of the battery.

[0097] For example, the location information of a battery cell can be represented by coordinates, for example, where the coordinates represent the row number and column number of the battery cell in the battery. For example, if a battery cell is located in the m1th row and n1th column of the battery, the location information of the battery cell can be represented as (m1, n1).

[0098] For example, the location information of a battery cell can also be a numerical value, or a keyword plus a numerical value. For example, if a battery includes multiple battery cells, the location information of the battery cell in the battery can be represented by a numerical value. For example, if the battery cells in a battery are sorted in the order of 10 according to the example shown in Figure 1, the location information of the battery cell can be 10. The location information can represent the position of each battery cell in the battery by one or more numerical values ​​and keywords. For example, if the battery cells in a battery are sorted in the order of 10 according to the example shown in Figure 1, the location information of the battery cell can be P10, where P represents the position mark and 10 represents the position of the battery cell.

[0099] Exemplarily, the location information of a battery cell may also be multiple numerical values, or a key character plus a numerical value. For example, if a battery includes multiple battery modules, and each battery module includes multiple battery cells, the location information may include location information representing the position of each battery cell in the battery through multiple numerical values. For example, if a battery cell is located in the third battery module, and the position sequence of the battery cell in the third battery module is 7, then the location information of the battery cell may be represented as 3-7. The location information may represent the position of each battery cell in the battery through multiple numerical values ​​and key characters. For example, if a battery cell is located in the third battery module, and the position sequence of the battery cell in the third battery module is 7, then the corresponding relationship information of the battery cell may be M3-7, where M represents the battery module mark, 3 represents the position sequence of the battery module in the battery, and 7 represents the position sequence of the battery cell in the battery module.

[0100] Step 420: Obtain chip identification information of the functional chip of the battery cell.

[0101] The functional chip is a chip installed on a battery cell and used to monitor the battery cell and collect its operating parameters. For example, the functional chip can be a cell monitoring unit. The chip identification information can be a unique identifier for the cell monitoring unit of each battery cell. The chip identification information can be a QR code, barcode, string, or other identifier that uniquely represents the cell monitoring unit. The chip identification information can be sent along with the data, meaning that each frame of data sent by the cell monitoring unit can carry its chip identification information.

[0102] For example, if a battery includes multiple rows and columns of battery cells, the chip identification information of each battery cell in the battery can be obtained sequentially starting from the first row and first column. For example, if a battery includes M rows and N columns of battery cells, the chip identification information of the battery cells in the first row can be obtained sequentially starting from the first row and first column, and the chip identification information of the battery cells in the first row can be obtained. After the chip identification information of the battery cell in the first row and N columns is obtained, the chip identification information of the battery cells in the second row can be obtained sequentially starting from the second row and N columns, and the chip identification information of the battery cells in the second row can be obtained. After the chip identification information of the battery cell in the second row and first column is obtained, the chip identification information of the battery cells in the third row can be obtained sequentially starting from the third row and first column, and so on, to obtain the chip identification information of each battery cell in the entire battery.

[0103] Of course, the chip identification information of the battery cells in each row may also be obtained starting from the first column.

[0104] For example, if a battery includes multiple battery modules, each battery module includes multiple rows and columns of battery cells. The chip identification information of all battery cells in each battery module can be obtained in sequence according to the order of the battery modules. For each battery module, the chip identification information of each battery cell in each battery module can be obtained in sequence. For example, the chip identification information of each battery cell in the battery can be obtained in sequence starting from the first row and the first column. Taking the first battery module including M1 rows and N1 columns of battery cells as an example, the chip identification information of the battery cells in the first row can be obtained in sequence starting from the first row and the first column until the chip identification information of the battery cell in the first row and the N1 column is obtained. Then, the chip identification information of the battery cells in the second row can be obtained in sequence starting from the second row and the N1 column until the chip identification information of the battery cell in the second row and the first column is obtained. Then, the chip identification information of the battery cells in the third row can be obtained in sequence starting from the third row and the first column until the chip identification information of the battery cell in the third row is obtained. And so on, the chip identification information of each battery cell in the entire battery can be obtained.

[0105] Optionally, the above steps 410 and 420 can be performed alternately. For example, after obtaining the location information of each battery cell, the chip identification information of the functional chip of the battery cell can be obtained. Therefore, after obtaining the location information and chip identification information of the battery cell each time, the two pieces of information can be associated.

[0106] Optionally, after obtaining the position information of all battery cells in the battery in step 410, the chip identification information of the functional chip of each battery cell can be obtained. Then, based on the relationship between each position information and the chip identification information, the corresponding relationship information between the position information and the chip identification information can be constructed.

[0107] Optionally, the order of steps 410 and 420 is not limited to the example shown in FIG. 4 . For example, when acquiring the chip identification information of each battery cell, the chip identification information can be stored sequentially in the order in which it was acquired, and then the position information of each battery cell can be determined according to the order in which the chip identification information was stored. For example, if the battery includes 96 battery cells, the 96 chip identification information items can be stored sequentially in an ordered array. For example, if a chip identification information is stored at position 37, it can indicate that the battery cell corresponding to the chip identification information is located at position 37 in the battery. The position information of the battery cell can then be represented as 37 or P37, etc.

[0108] Step 430 : storing the correspondence information between the position information of the battery cell and the chip identification information in the battery management unit of the battery.

[0109] The chip identification information can be used to implement communication between the battery management unit and the functional chip of the battery cell. For example, when the battery management unit needs to communicate with each functional chip, it can use the identification information to implement communication with the functional chip.

[0110] The corresponding relationship information is used to indicate the position of the battery cell in the battery and the chip identification information of each battery cell. For example, the corresponding relationship information may include the chip identification information and position information of each battery cell.

[0111] Optionally, after obtaining the chip identification information of each battery cell of the battery, it can be stored in the order of acquisition. When the chip identification information is needed, the relationship between each chip identification information and the position information of each battery cell can be determined according to the storage order to construct the corresponding relationship information between the position information of the battery cell and its chip identification information.

[0112] Alternatively, the correspondence information may be formed by combining the position information of each battery cell with the chip identification information. For example, if the battery cell in a battery is sorted in the example shown in FIG1 and the chip identification information of the battery cell is ID13, the correspondence information may be represented as 13_ID13 or P13_ID13.

[0113] For another example, a battery cell is located in the first battery module, and the position sequence of the battery cell in the first battery module is 5, and the chip identification information of the battery cell is ID15, then the corresponding relationship information of the battery cell can be expressed as 1-5_ID15 or M1-5_ID15.

[0114] Optionally, the location information of a battery cell and its chip identification information can be bound to determine the corresponding relationship information of one of the battery cells. For example, if the location information of a battery cell is P37 and the chip identification information of the battery cell is ID37, the corresponding relationship information of the battery cell may include P37 and ID37. In the corresponding relationship information stored in the battery management unit, the chip identification information of the battery cell can be queried using P37 to determine that it is ID37. In the corresponding relationship information stored in the battery management unit, the location information of the battery cell can be queried using the chip identification information ID37 to determine that it is P37.

[0115] Optionally, after the battery management unit obtains the correspondence information, it can also send the correspondence information to the battery cell monitoring unit corresponding to each battery cell, so that each battery cell monitoring unit can also store the correspondence information. For example, if the battery management unit of the battery is damaged and needs to be replaced with a new battery management unit, before the battery management unit is put into use, the correspondence information of each battery cell can be obtained from each battery cell monitoring unit. For another example, if the battery management unit of the battery is damaged and the correspondence information recorded in it is lost, before the battery management unit is put into use, each battery cell monitoring unit can first send the correspondence information of each battery cell to the battery management unit so that the battery management unit can store the correspondence information.

[0116] In this embodiment, by storing the chip identification information of each battery cell in the battery management unit, the battery management unit can accurately know the battery cell monitoring unit contained in the battery it manages, and thus communicate with the battery cell monitoring unit it contains, and can more accurately obtain the working parameters of each battery cell it contains.

[0117] In an optional implementation, step 410 may include: acquiring position information of the battery cells in the battery according to a preset order.

[0118] Exemplarily, the position information of the battery cells in the battery may be acquired sequentially in the order of the dotted arrows shown in FIG. 1 .

[0119] Before obtaining the chip identification information of the functional chip of the battery cell, the position information of the battery cell can be obtained according to the sequence of the dotted arrows; after obtaining the position information of the battery cell, the chip identification information of the functional chip of the battery cell can be obtained. Repeating steps 410 and 420 in the sequence of the dotted arrows shown in Figure 1 can complete the acquisition of the position information and chip identification information of the battery cell in the battery.

[0120] In an optional implementation, step 410 may include: acquiring chip identification information of a functional chip of the battery cell according to the location information of the battery cell.

[0121] Optionally, after the position information of any battery cell is determined, the chip identification information of the battery cell may be acquired immediately.

[0122] Optionally, the position of each battery cell can be located according to the position information of each battery cell to read the chip identification information of the functional chip of the battery cell at that position. For example, after obtaining the chip identification information, the chip identification information can be associated with the position information of the battery cell.

[0123] The battery provided in this embodiment may include multiple battery modules, each of which includes multiple battery cells. On this basis, as shown in FIG5 , step 420 may include steps 421 to 423 .

[0124] Step 421 : sequentially obtain chip identification information of each battery cell in the battery module according to the first position information of the battery cell.

[0125] In one embodiment, after the battery module is assembled, the chip identification information of each battery cell in the battery module is scanned in sequence by a scanning device according to the first position information of the battery cell.

[0126] For example, if a battery module may include M1 rows and N1 columns of battery cells, the first position information of each battery cell in the battery module may be determined sequentially from the first row to the M1th row, and from the first column to the N1th column for each row. The chip identification information of the M1*N1 battery cells in the battery module may then be scanned sequentially from the first row to the M1th row, and from the first column to the N1th column for each row using a scanning device.

[0127] For example, the chip identification information of each battery cell can be marked on the battery cell monitoring unit of the battery cell. For example, the chip identification information can be engraved on the surface of the battery cell monitoring unit to facilitate scanning of the chip identification information by a scanning device.

[0128] In another embodiment, the first position information of the battery cell can be determined in sequence according to the assembly order of the battery cell during the assembly of the battery module. Then, the chip identification information of each battery cell used to assemble the battery module can be obtained in sequence according to the assembly order of each battery cell.

[0129] For example, when assembling the battery module, the first position information of each battery cell in the assembled battery module may be determined, and the chip identification information of each battery cell may be collected.

[0130] In another embodiment, after the battery module is assembled, the chip identification information of each battery cell used to assemble the battery module is sequentially acquired based on the first position information of the battery cell.

[0131] For example, after each battery module is assembled, the first position information of each battery cell in the battery module can be determined in sequence according to a set order. The chip identification information of the battery cells in the battery module can also be scanned in sequence according to the first position information of each battery cell. The set order can be from the first row to the M1th row, with each row being scanned in sequence from the first column to the N1th column. Alternatively, a serpentine order can be used, for example, odd-numbered rows can be scanned in sequence from the first column to the N1th column, and even-numbered rows can be scanned in sequence from the N1th column to the first column.

[0132] Step 422 : Generate a module identification according to the chip identification information of the battery cell of the battery module and the first position information of the battery cell.

[0133] The module identification includes chip identification information and location information of the battery cells included in the battery module.

[0134] Exemplarily, the module identifier may include the chip identifier information of all battery cells contained in the battery module, as well as the position information of each battery cell in the battery module. For example, the position information of the i-th battery cell in a battery module can be expressed as Mx-i, where x represents the position to be determined. Once the position of the battery module in the battery is determined, the position to be determined can be determined. For example, if the battery module is installed in the fourth position in the entire battery, the value of x can be 4.

[0135] Step 423 : Obtain the module identification of each battery module in sequence according to the second position information of the battery module in the battery.

[0136] Optionally, after each battery module is assembled into a battery, the module identification of each battery module is scanned in sequence by a scanning device according to the position of each battery module in the battery.

[0137] For example, if the order of the battery module in the battery is the jth position, the position information of the i battery cells in the battery module can be expressed as Mj-i.

[0138] The correspondence information may include first position information representing each battery cell in the battery module, second position information representing the position of the battery module where the battery cell is located in the battery, and chip identification information of the functional chip of the battery cell.

[0139] The corresponding relationship information may include the relationship information between the location information of each battery cell and the chip identification information. The associated information of each battery cell may be represented by a string of characters, or may be presented by binding the location information with the chip identification information.

[0140] If the battery module is ranked in the jth order in the battery, the position information of the i-th battery cell in the battery module can be represented as Mj-i, and the chip identification information of the battery cell can be represented as IDji. In one example, the associated information of a battery cell is represented by a string of characters, and the associated information of the battery cell can be represented as Mj-i_IDji. In another example, only the position information Mj-i and the chip identification information IDji can be bound and stored in the battery management unit. The battery management unit can query the chip identification information of the battery cell as IDji through the position information Mj-i, and the battery management unit can also query the position information of the battery cell as Mj-i through the chip identification information IDji of the battery cell.

[0141] Further, step 430 may include: determining the correspondence information between the position information of the battery cell and the chip identification information based on the second position information and the module identification; storing the correspondence information between the position information of the battery cell and the chip identification information in the battery management unit of the battery, wherein the battery management unit communicates with the functional chip through the identification information.

[0142] In this embodiment, if the battery is composed of multiple battery modules, an intermediate identification module identification can be formed first, which can reduce the complexity of the position information and make the relative position of each battery cell clearer, so that the position relationship of each battery cell expressed by the corresponding relationship information can be more accurate.

[0143] In addition to the chip identification information uniquely corresponding to the battery cell monitoring unit it contains, each battery cell may also include cell identification information that records battery cell production information and battery cell characteristic information. Therefore, the cell identification information may also be included in the correspondence information stored in the battery management unit. Prior to step 410, the battery coding method may also include: after each battery cell is manufactured, obtaining the cell identification information and chip identification information of each battery cell, and storing the cell identification information of each battery cell in association with the chip identification information.

[0144] Step 430 may include: storing the corresponding relationship information of the battery cell, the chip identification information, and the cell identification information in a battery management unit of the battery.

[0145] Each battery cell monitoring unit is bound to each battery cell during the production of the battery cell. After each battery cell is offline, the chip identification information can be used as the identification of the battery cell.

[0146] Optionally, when the cell monitoring unit is assembled on the battery cell and physical binding of the cell monitoring unit and the battery cell is achieved, a barcode scanning device can be used to scan the cell identification information and the chip identification information, and the cell identification information and the chip identification information can be bound.

[0147] Therefore, when obtaining the cell identification information of any battery cell, the chip identification information of the battery cell can be determined from the pre-associated stored data; when obtaining the chip identification information of any battery cell, the cell identification information of the battery cell can be determined from the pre-associated stored data.

[0148] In one example, if a battery module is ranked jth in the battery hierarchy, the position information of the i-th battery cell in the battery module can be represented as Mj-i, the chip identification information of the battery cell can be represented as IDji, and the cell identification information of the battery cell can be represented as ID-ji. In another example, the associated information of a battery cell is represented by a string of characters, and the associated information of the battery cell can be represented as Mj-i_IDji_ID-ji.

[0149] In another example, the chip identification information of the battery cell with position information P37 may be ID37, and the cell identification information of the battery cell may be ID-37, then the corresponding relationship information of the battery cell may be expressed as P37_ID37_ID-37.

[0150] The implementation process of the above-mentioned battery encoding method realizes the networking process when the battery is assembled for the first time, that is, when the battery management unit sends information, it only communicates with the cell monitoring units whose chip identification information already exists in its own storage list, and does not communicate with the cell monitoring units whose chip identification information does not exist, thereby avoiding the battery from communicating with the cell monitoring units of other batteries or battery cells to be assembled.

[0151] The advantage of the above encoding method is that the battery management unit in each battery has its own chip identification information of the battery cell monitoring unit that needs to communicate, and the abnormal battery cell position can be quickly located based on the chip identification information and its corresponding position information.

[0152] During the application process of the above-mentioned battery, it only communicates with the battery cell monitoring unit whose chip identification information exists in its own list, which is equivalent to identity authentication, improves the reliability of data communication, and prevents subsequent hackers from disguising the battery cell monitoring unit information, affecting communication, and stealing data (increasing the decoding process); in addition, each battery cell monitoring unit stores its own location identification, providing a backup. When an abnormality occurs in the battery management unit and the list information of the chip identification information of the battery cell monitoring unit is lost, after using a new battery management unit, the data from each battery cell monitoring unit can be read back, avoiding the need to re-scan the code for confirmation.

[0153] The following two examples describe the process of the battery encoding method:

[0154] If the battery cells are directly assembled into batteries, the battery coding can be performed through the following process:

[0155] The battery cell monitoring chip on each battery cell monitoring unit needs to have its own unique chip identification information. This unique chip identification information can be sent along with its data (that is, each frame of data sent by the battery cell monitoring unit has chip identification information). This unique chip identification information can be marked on the chip casing of the battery cell monitoring unit of the battery cell through a QR code.

[0156] Binding the cell monitoring unit to a single battery cell: After each battery cell is offline, it will have its own unique identification information, which can be a QR code. When assembling the cell monitoring unit to a single battery cell, a barcode scanner is used to scan the QR code of the battery cell and the QR code of the chip to achieve software binding between the cell monitoring unit and the single battery cell. Furthermore, the cell monitoring unit chip is integrated into the single battery cell, achieving physical binding. Therefore, the unique chip identification information of the cell monitoring unit can be used as the identification of the entire battery cell.

[0157] After the battery cells are assembled into a battery, use a barcode scanner to scan the QR code of each battery cell in sequence. For example, you can start with BAT- as the first one;

[0158] Through the above operation process, the corresponding relationship can be obtained: for example, P1_ID1_ID-1, the first battery cell of the battery, the corresponding chip identification information of the cell monitoring unit is ID1, and the corresponding battery cell identification information is ID-1;

[0159] Therefore, through the chip identification information of each battery cell that sends data, we can parse the physical location of the battery cell in the battery.

[0160] If you need to first assemble battery cells into battery modules and then assemble the battery modules into batteries, you can use the following process to encode the batteries:

[0161] Binding the cell monitoring unit to a single battery cell: After each battery cell is offline, it will have its own unique identification information, which can be a QR code. When assembling the cell monitoring unit to a single battery cell, a barcode scanner is used to scan the QR code of the battery cell and the QR code of the chip to achieve software binding between the cell monitoring unit and the single battery cell. Furthermore, the cell monitoring unit chip is integrated into the single battery cell, achieving physical binding. Therefore, the unique chip identification information of the cell monitoring unit can be used as the identification of the entire battery cell.

[0162] After the battery cells are assembled into a battery module, use a barcode scanner to scan the QR code information of the battery cell monitoring unit one by one from negative to positive in the battery module, and then generate a module QR code. The QR code must contain the order of the chip identification information of the battery cell monitoring unit. For example: Mx-1, Mx-2, x is a reserved position and can be marked with a symbol that specifically represents the order of the battery module, such as 1, 2 or I, II;

[0163] After the battery modules are assembled into a battery, use a barcode scanner to scan each module's QR code in sequence (usually starting with BAT-). The module sequence information is written into the reserved marking positions to form: M1-1, M1-2, M2-2, etc. This means that the sequence information of the battery modules and the sequence information of the battery cells in the battery module can be formed and bound to each other.

[0164] The corresponding relationship can be obtained through the above method: for example, M1-1_ID1_ID-1 can identify the first battery cell of module 1. The corresponding ID number of the battery cell monitoring unit is ID1, and the corresponding ID number of the battery cell is ID-1.

[0165] Then, after the host computer completes the above processing process, it can send the corresponding information to the battery management unit of the battery. The battery management unit stores the data in the memory and sends the data to each battery monitoring unit through the wireless management unit. The battery monitoring unit writes the location information consistent with its own chip identification information into its own memory, and the storage location is protected;

[0166] At the same time, this process also realizes the networking process of the battery during the first assembly, that is, when the battery management unit sends information, it only communicates with the cell monitoring units whose chip identification information already exists in its own storage list, and does not communicate with the cell monitoring units whose chip identification information does not exist in the list, thereby avoiding the battery from communicating with other batteries or battery cells to be assembled, thereby improving the effectiveness of the battery management unit.
