Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of batteries, and in particular, to an address allocation method, device, battery, and storage medium. Background Art

[0002] With the development of technology, batteries are widely used in many industries and are maintaining a high growth rate. In the actual application process, due to the capacity limitation of a single battery, multiple batteries are usually used in parallel, that is, there are multiple parallel-connected batteries in the battery system. Due to the parallel connection of the batteries in the battery system, it is necessary to allocate addresses to the batteries to facilitate the detection of the status of each battery box.

[0003] In the related art, by obtaining the power-on time of each battery in the battery system, the order of address sizes is determined according to the sequence of the power-on times, and the corresponding addresses in the address table are obtained.

[0004] However, when multiple batteries are powered on at the same time, the power-on times may be the same, and it is possible that the address allocation fails. Therefore, it is difficult to accurately allocate non-conflicting addresses to each battery by the above method. Summary of the Invention

[0005] The embodiments of the present application provide an address allocation method, device, battery, and storage medium for accurately allocating non-conflicting addresses to each battery.

[0006] In a first aspect, the embodiments of the present application provide a first address allocation method, which is applied to a target battery. The target battery is any battery in the battery system, and the battery system includes multiple parallel-connected batteries; the method includes:

[0007] When in the power-on state, compare the initial address of the target battery with the address range of the battery system;

[0008] Based on the comparison result, serial number (Serial Number, SN) code, and initial address of the target battery, generate the first information corresponding to the target battery, and obtain the first information sent by the first battery and the second information sent by the second battery; wherein, the first battery is other batteries in the power-on state in the battery system, and the second battery is the battery that has been allocated the target address, and the second information includes the SN code and the target address of the second battery;

[0009] Based on the first information and the second information, determine the target address of the target battery.

[0010] In the above solution, when the battery is powered on, by comparing its initial address with the address range of the battery system, it can be known whether the initial address meets the basic requirements of the battery system; each powered-on battery will send its own relevant information (its own comparison result, SN code, and initial address), and obtain the relevant information of other batteries (the comparison results, SN codes, and initial addresses of the powered-on batteries, and the SN codes and initial addresses of the batteries with assigned target addresses); based on the first information and the second information, in addition to being able to know the initial addresses / target addresses of all other batteries, the SN code that uniquely identifies the battery can also be known, so that even if there is an address conflict, the situation of occupying the target address can be avoided. Therefore, based on the first information and the second information, the target address of itself is determined, which will not occupy the existing target addresses on the bus and will not affect the normal operation of other batteries on the bus. In addition, the battery only executes this method in the initial stage of power-on, and there will be no more data related to address allocation on the bus after the address allocation is completed, reducing the bus load rate.

[0011] In some optional embodiments, based on the first information and the second information, determining the target address of the target battery includes:

[0013] Based on the address range of the battery system and the occupied addresses, determine the remaining addresses in the battery system;

[0014] Based on the SN code of the abnormally occupied battery, sort the abnormally occupied batteries, and determine the target address corresponding to the target battery from the remaining addresses based on the order of the target battery among the abnormally occupied batteries; where the abnormally occupied battery is a battery in the battery system whose initial address is not within the address range.

[0017] In some optional embodiments, based on the order of the target battery among the abnormally occupied batteries, determining the target address corresponding to the target battery from the remaining addresses includes:

[0019] In some optional embodiments, determining the target address of the target battery based on the first information and the second information includes:

[0020] If the initial address of the target battery is within the address range and there is an address in the second information that is the same as the initial address of the target battery, then determine a preset address as the new initial address of the target battery, and re - execute the step of comparing the initial address of the target battery with the address range of the battery system; wherein, the preset address is not within the address range.

[0021] In some optional embodiments, determining the target address of the target battery based on the first information and the second information includes:

[0022] If the initial address of the target battery is within the address range and there is no address in the second information that is the same as the initial address of the target battery, then determine whether there is an address in the first information that is the same as the initial address of the target battery;

[0023] If so, determine the target address of the target battery based on the SN code of the target battery;

[0024] Otherwise, determine the initial address of the target battery as the target address.

[0025] In some optional embodiments, determining the target address of the target battery based on the SN code of the target battery includes:

[0026] If the SN code of the target battery is greater than the SN code corresponding to the same address, then determine the initial address of the target battery as the target address;

[0027] Otherwise, determine a preset address as the new initial address of the target battery, and re - execute the step of comparing the initial address of the target battery with the address range of the battery system; wherein, the preset address is not within the address range.

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0043] The terms "first" and "second" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0044] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, it may be directly connected, or indirectly connected through an intermediate medium, and may be the connection inside two devices. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to specific situations.

[0045] In the actual application process, due to the capacity limitation of a single battery, multiple batteries are usually used in parallel, that is, there are multiple parallel-connected batteries in the battery system. Refer to Figure 1 As shown, the battery system includes parallel-connected Battery 1, Battery 2,..., Battery n. Due to the parallel connection of the batteries in the battery system, it is necessary to assign addresses to the batteries to facilitate the detection of the status of each battery box.

[0046] In the related art, by obtaining the power-on time of each battery in the battery system, the order of address sizes is determined according to the sequence of the power-on times, and the corresponding addresses in the address table are obtained.

[0047] However, when multiple batteries are powered on simultaneously, the power-on times may be the same, and address allocation failures may occur. Therefore, it is difficult to accurately allocate non-conflicting addresses to each battery by the above method.

[0048] In some embodiments, the order of address sizes is directly determined based on the SN code sizes of the batteries. However, in this way, the battery management system (Battery Management System, BMS) needs to send data frames indicating that the address allocation of the bus batteries has been completed in real time, which will increase the load rate of the bus and may cause bus congestion and data loss when there is a large amount of bus data.

[0049] In view of this, an address allocation method, device, battery and storage medium are provided in an embodiment of the present application. The method is applied to a target battery, where the target battery is any battery in a battery system, and the battery system includes a plurality of batteries connected in parallel. The method includes: when in the powered-on state, comparing the initial address of the target battery with the address range of the battery system; generating first information corresponding to the target battery based on the comparison result, SN code and initial address of the target battery, and obtaining the first information sent by a first battery and the second information sent by a second battery; where the first battery is other batteries in the powered-on state in the battery system, and the second battery is a battery to which a target address has been allocated, and the second information includes the SN code and the target address of the second battery; determining the target address of the target battery based on the first information and the second information.

[0050] In the above solution, when the battery is powered on, by comparing its own initial address with the address range of the battery system, it can be known whether the initial address meets the basic requirements of the battery system; each battery will send its own relevant information (its own comparison result, SN code and initial address) when powered on, and obtain the relevant information of other batteries (the comparison result, SN code and initial address of the powered-on battery, the SN code and initial address of the battery to which the target address has been allocated); based on the first information and the second information, in addition to knowing the initial addresses / target addresses of all other batteries, the SN code that uniquely identifies the battery can also be known, so that even if there is an address conflict, the situation of occupying the target address can be avoided. Therefore, determining its own target address based on the first information and the second information will not occupy the existing target address on the bus, nor will it affect the normal operation of other batteries on the bus. In addition, the battery only executes this method in the initial stage of power-on. After the address allocation is completed, no address allocation-related data will appear on the bus, reducing the bus load rate.

[0051] Next, the technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail in conjunction with the accompanying drawings and specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0052] Figure 2 It is a schematic flow chart of the first address allocation method provided in an embodiment of the present application, as Figure 2 shown, and includes the following steps:

[0053] Step S201: When in the powered-on state, compare the initial address of the target battery with the address range of the battery system.

[0054] During implementation, after the battery is powered on, it will read data from a specific location in the storage chip, and the read data can be used as the initial address of the battery. However, this initial address may not necessarily be within the address range of the battery system.

[0055] Exemplarily, the battery system is set with an address range of 0 - N, where N can be the maximum number of parallel batteries in the battery system; the target address finally allocated to the battery needs to be within the address range of the battery system so that the battery system can manage the battery based on the target address, that is, only when the target address is within the address range can it meet the basic requirements of the battery system for address allocation.

[0056] Based on this, when each battery in this embodiment is powered on, it first compares its own initial address with the address range of the battery system, and then it can know whether the initial address meets the basic requirements of the battery system.

[0057] Step S202: Generate the first information corresponding to the target battery based on the comparison result, SN code, and initial address of the target battery, and obtain the first information sent by the first battery and the second information sent by the second battery.

[0058] Among them, the first battery is other batteries in the battery system with a powered-on state, and the second battery is a battery that has been allocated a target address. The second information includes the SN code and target address of the second battery.

[0059] In this embodiment, in addition to being within the address range of the battery system, the target address finally allocated to the battery cannot conflict with the addresses of other batteries. Based on this, the batteries in the powered-on state (which have not been allocated a target address) send the comparison result, SN code, and initial address to other batteries, and the batteries that have been allocated a target address only need to send the SN code and target address (which must be within the above address range) to other batteries; in this way, each battery can know the address-related information of other batteries.

[0060] Exemplarily, different identification information can be used to distinguish the comparison results of the first information. For example, "0x030303XX" indicates that the initial address of the battery is not within the address range of the battery system, and "0x050505XX" indicates that the initial address of the battery is within the address range of the battery system. Different identification information can also be used to distinguish the first information from the second information. For example, "0x18**01XX" indicates the second information. Based on the identification information, it can be determined whether it is the first information or the second information, and the comparison result of the corresponding battery can be determined when it is the first information. Details will not be elaborated one by one hereafter.

[0061] Step S203: Determine the target address of the target battery based on the first information and the second information.

[0062] The first information carries the battery comparison result, SN code, and initial address in the powered-on state, and the second information carries the SN code and target address. Therefore, after integrating the first information and the second information, the battery can learn the initial addresses / target addresses of all other batteries and the SN code that uniquely identifies the battery. In this way, even if there is an address conflict, the situation of occupying the target address can be avoided. Therefore, based on the first information and the second information, the battery determines its own target address without occupying the existing target addresses on the bus and without affecting the normal operation of other batteries on the bus.

[0063] In the above solution, when the battery is powered on, by comparing its own initial address with the address range of the battery system, it can be known whether the initial address meets the basic requirements of the battery system. Each powered-on battery will send its own relevant information (its own comparison result, SN code, and initial address) and obtain the relevant information of other batteries (the comparison results, SN codes, and initial addresses of the powered-on batteries, and the SN codes and initial addresses of the batteries with allocated target addresses). Based on the first information and the second information, in addition to learning the initial addresses / target addresses of all other batteries, the battery can also learn the SN code that uniquely identifies the battery. In this way, even if there is an address conflict, the situation of occupying the target address can be avoided. Therefore, based on the first information and the second information, the battery determines its own target address without occupying the existing target addresses on the bus and without affecting the normal operation of other batteries on the bus. In addition, the battery only executes this method in the initial stage of power-on. After the address allocation is completed, no address allocation-related data will appear on the bus, reducing the bus load rate.

[0064] The following will be described separately for different situations.

[0065] Figure 3 The flowchart of the second address allocation method provided by the embodiment of the present application is shown in Figure 3 and includes the following steps:

[0066] Step S301: When in the powered-on state, compare the initial address of the target battery with the address range of the battery system.

[0067] Step S302: Based on the comparison result, SN code, and initial address of the target battery, generate the first information corresponding to the target battery, and obtain the first information sent by the first battery and the second information sent by the second battery.

[0068] Among them, the first battery is other batteries in the powered-on state in the battery system, and the second battery is the battery with an allocated target address. The second information includes the SN code and target address of the second battery.

[0069] The specific implementation manners of steps S301 to S302 can refer to other embodiments and will not be elaborated here.

[0070] Step S303: If the initial address of the target battery is not within the address range, determine the occupied addresses in the battery system based on the first information and the second information.

[0071] As described above, in addition to being within the address range of the battery system, the finally allocated target address of the battery cannot conflict with the addresses of other batteries. Based on this, in this embodiment, it is necessary to comprehensively consider the first information and the second information to determine which addresses within the address range of the battery system are occupied, and the target addresses of subsequent batteries cannot conflict with these addresses.

[0072] Step S304: Determine the remaining addresses in the battery system based on the address range of the battery system and the occupied addresses.

[0073] In this embodiment, within the address range of the battery system, except for the above-mentioned occupied addresses, the remaining addresses can all be allocated; therefore, it is necessary to determine which remaining addresses within the address range are available based on the address range of the battery system and the occupied addresses.

[0074] Step S305: Sort the abnormally occupied batteries based on the SN codes of the abnormally occupied batteries, and determine the target address corresponding to the target battery from the remaining addresses based on the order of the target battery among the abnormally occupied batteries.

[0075] Among them, the abnormally occupied battery is a battery in the battery system whose initial address is not within the address range.

[0076] In implementation, the remaining addresses are all addresses that can be used within the address range of the battery system. If these remaining addresses are directly allocated randomly, although there will be no conflict with the previously occupied addresses, when there are multiple batteries not within the address range (abnormally occupied batteries), there may be an address conflict between these multiple abnormally occupied batteries;

[0077] Based on this, in this embodiment, all abnormally occupied batteries are sorted, and the corresponding target addresses are determined from the remaining addresses according to the order, reducing the address conflict between the abnormally occupied batteries.

[0078] In the above solution, by comprehensively considering the first information and the second information, it is determined which addresses within the address range of the battery system are occupied; based on the address range of the battery system and the occupied addresses, it is determined which remaining available addresses are within the address range, so that the target addresses of subsequent batteries do not conflict with the occupied addresses; by sorting all abnormally occupied batteries and determining the corresponding target addresses from the remaining addresses according to the order, the address conflict between the abnormally occupied batteries is reduced.

[0079] In some alternative embodiments, step S303 above may be implemented by, but not limited to, the following method:

[0080] Determine the initial address in the first information corresponding to the normally occupied battery and the target addresses in all the second information as the occupied addresses.

[0081] Wherein, the normally occupied battery is the battery in the battery system whose initial address is within the address range.

[0082] In implementation, the addresses in the above second information are all allocated target addresses, and the addresses in the first information of the abnormally occupied battery are not within the address range of the battery system, and these addresses are invalid per se, while the addresses in the first information of the normally occupied battery are within the address range of the battery system and are valid. Therefore, within the address range of the battery system, the initial address corresponding to the normally occupied battery and the target addresses in all the second information all belong to the occupied addresses, and the target addresses of subsequent batteries cannot conflict with these addresses.

[0083] In the above solution, by determining the initial address in the first information corresponding to the normally occupied battery and the target addresses in all the second information as the occupied addresses, the target addresses of subsequent batteries are made not to conflict with the allocated and determined-to-be-allocated target addresses.

[0084] In some alternative embodiments, step S305 above may be implemented by, but not limited to, the following method:

[0085] Determine the address at the corresponding position of the order in the remaining addresses as the target address corresponding to the target battery.

[0086] Since the positions of the remaining addresses are different (which can also be understood as different in size order), by determining the positions of the remaining addresses, and then determining the position corresponding to the order of the batteries, and determining the address at this position as the target address, the target addresses of the abnormally occupied batteries are made different from each other, avoiding address conflicts between these abnormally occupied batteries.

[0087] Figure 4 It is a schematic flowchart of the third address allocation method provided by the embodiment of the present application. As Figure 4 shown, it includes the following steps:

[0088] Step S401: When in the powered-on state, compare the initial address of the target battery with the address range of the battery system.

[0089] Step S402: Generate the first information corresponding to the target battery based on the comparison result, SN code, and initial address of the target battery, and obtain the first information sent by the first battery and the second information sent by the second battery.

[0090] Wherein, the first battery is a battery in other powered-on states in the battery system, the second battery is a battery to which a target address has been assigned, and the second information includes the SN code and the target address of the second battery.

[0091] The specific implementation manners of steps S401 to S402 may refer to other embodiments and will not be elaborated here.

[0092] Step S403: If the initial address of the target battery is within the address range and there is an address in the second information that is the same as the initial address of the target battery, then determine a preset address as the new initial address of the target battery, and re-execute the step of comparing the initial address of the target battery with the address range of the battery system.

[0093] Wherein, the preset address is not within the address range.

[0094] In implementation, if the initial address of the target battery is within the address range of the battery system, then this initial address is valid. However, if its initial address conflicts with the assigned target address (there is an address in the second information that is the same as this initial address), then the target battery still cannot use this initial address; by determining a preset address that is not within the address range as the new initial address of the target battery and re-executing the step of comparing the initial address of the target battery with the address range of the battery system, the process corresponding to the case where the initial address of the target battery is not within the address range can be followed to re-obtain the target address. For details, reference can be made to Figure 3 the corresponding embodiments.

[0095] Figure 5 is a flowchart of a fourth address allocation method provided by an embodiment of the present application. As Figure 5 shown, it includes the following steps:

[0096] Step S501: When powered on, compare the initial address of the target battery with the address range of the battery system.

[0097] Step S502: Generate first information corresponding to the target battery based on the comparison result, SN code, and initial address of the target battery, and obtain the first information sent by the first battery and the second information sent by the second battery.

[0098] Wherein, the first battery is a battery in other powered-on states in the battery system, the second battery is a battery to which a target address has been assigned, and the second information includes the SN code and the target address of the second battery.

[0099] The specific implementation manners of steps S501 to S502 may refer to other embodiments and will not be elaborated here.

[0100] Step S503: If the initial address of the target battery is within the address range and there is no address in the second information that is the same as the initial address of the target battery, determine whether there is an address in the first information that is the same as the initial address of the target battery.

[0101] If so, execute Step S504; otherwise, execute Step S505.

[0102] In implementation, if the initial address of the target battery is within the address range of the battery system, then the initial address is valid; if there is no address in the second information that is the same as the initial address, its initial address will not conflict with the assigned target address.

[0103] However, if the initial addresses of these batteries are all retained, there may be address conflicts between these batteries; based on this, this embodiment also needs to determine whether there are the same addresses between these batteries, that is, to check whether there is an address in the received first information that is the same as the initial address of the target battery itself.

[0104] In implementation, if there is an address that is the same as the initial address of the target battery, only one of the same addresses can be retained. Since the SN code of the battery is the information that uniquely identifies the battery, the target battery using this address can be determined according to the SN code, and then its own target address can be determined, that is, execute Step S504.

[0105] On the contrary, if there is no address that is the same as the initial address of the target battery, then the target battery can directly use the initial address without conflicting with any battery, that is, execute Step S505.

[0106] Step S504: Based on the SN code of the target battery, determine the target address of the target battery.

[0107] Step S505: Determine the initial address of the target battery as the target address.

[0108] In the above solution, for the case where the initial address of the target battery is within the address range of the battery system and there is no address in the second information that is the same as the initial address, its initial address will not conflict with the allocated target address. However, if the initial addresses of these batteries are all retained, there may be an address conflict between these batteries. By determining whether there are the same addresses among these batteries, that is, the target battery checks whether there is an address in the received first information that is the same as its own initial address. If there is an address that is the same as the initial address of the target battery, only one of the same addresses can be retained. Since the SN code of the battery is the information that uniquely identifies the battery, the battery that uses this address can be determined according to the SN code, and then its own target address can be determined. If there is no address in the first information that is the same as the initial address of the target battery, the target battery can directly use the initial address without conflicting with any other battery.

[0109] In some alternative embodiments, determining the target address of the target battery based on the SN code of the target battery includes:

[0110] If the SN code of the target battery is greater than the SN code corresponding to the same address, the initial address of the target battery is determined as the target address;

[0111] Otherwise, a preset address is determined as the new initial address of the target battery, and the step of comparing the initial address of the target battery with the address range of the battery system is re-executed; wherein, the preset address is not within the address range.

[0112] In implementation, for the case where there is an address that is the same as the initial address of the target battery, only one of the same addresses can be retained. Since the SN code of the battery is the information that uniquely identifies the battery, the battery that uses this address can be determined according to the SN code, and then its own target address can be determined.

[0113] In order to enable all batteries to determine which battery's same address to retain according to the same rule, the battery with the largest SN code can be retained. That is, if the SN code of the target battery is greater than the SN codes corresponding to other same addresses, the target battery retains its initial address, that is, the initial address is determined as the target address;

[0114] If the SN code corresponding to another same address is greater than the SN code of the target battery, the target battery still cannot use the initial address. By determining a preset address that is not within the address range as the new initial address of the target battery and re-executing the step of comparing the initial address of the target battery with the address range of the battery system, the process corresponding to the case where the initial address of the target battery is not within the address range can be followed, and the target address can be re-obtained. Specifically, reference can be made to Figure 3 the corresponding embodiment.

[0115] Such asFigure 6 As shown in Figure 6 , an address allocation device 600 is provided in an embodiment of the present application, which is applied to a target battery.
