Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
Because the voltage capacity of a single battery pack cannot meet the user requirements generally, in practical application, a plurality of battery packs are combined in parallel, and when a plurality of battery packs are used in parallel, a controller for controlling the plurality of battery packs needs to communicate with the battery packs. In a controller area network (CANBus) communication network, each battery pack must have different identification Information (ID) to distinguish and identify the master and slave battery packs from each other and to communicate with each other. At present, identification information of the battery pack is manually distributed, so that the efficiency is low and errors are easy to make.
It can be understood that, in use, when a user pulls out any battery pack from a plurality of battery packs connected in parallel with each other or inserts a new battery pack, all the battery packs connected in parallel with each other need to be reassigned with different identification Information (ID), and the use of the conventional manual assignment method is not only inefficient, error-prone and inconvenient for installation and maintenance.
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples. Fig. 1 is a system configuration diagram of a battery pack identification information distribution system according to a first embodiment of the present application. As shown in fig. 1, the battery pack identification information distribution system 10 provided in this embodiment includes at least two battery packs 102 and a controller 101 connected in parallel, wherein the at least two battery packs 102 and the controller 101 are connected through a controller area network communication bus 103.
In an alternative implementation, the controller 101 sends the instruction for allocating identification information to each battery pack 102 in response to the instruction for allocating identification information.
It is understood that the instruction for allocating the identification information may be sent by a user terminal, or may be triggered by a user through a control interface of the battery pack identification information allocation system 10, and in some application scenarios, when the user inserts a new battery pack or removes the battery pack, the instruction for allocating the identification information may also be triggered, which is not limited herein.
It should be noted that the controller 101 is generally configured to respond to a communication command and communicate with each battery pack 102 according to the communication command, and in order to ensure smooth communication, identification information needs to be allocated to each battery pack 102.
After detecting the identification information distribution instruction, each battery pack 102 collects the corresponding battery core data within a preset time period, and sends the corresponding battery core data to all other battery packs connected in parallel with each other, in this embodiment, the battery pack except for the battery core data among all the battery packs connected in parallel with each other is defined as a target battery pack.
It should be noted that when each battery pack 102 is in a sleep or off state, there is no communication with the controller lan communication bus 103, and after each battery pack 102 is awakened, it may detect an instruction transmitted on the controller lan communication bus 103.
In an optional implementation manner, the cell data includes a first cell voltage value, a second cell voltage value, and an average cell temperature value, where the second cell voltage value is greater than the first cell voltage value, for example, the second cell voltage value is a maximum cell voltage value within the preset duration, and the first cell voltage value is a minimum cell voltage value within the preset duration. In this example, the first cell voltage value, the second cell voltage value, and the average cell temperature value are all represented using 16-ary double-byte data.
As can be understood, each battery pack 102 transmits the corresponding cell data to a target battery pack through the controller area network communication bus 103, where the target battery pack is a battery pack of all battery packs except for the battery pack that transmits the cell data.
Each battery pack 102 determines corresponding identification information according to the electric core data of all the battery packs.
It should be noted that, in the use process of the battery packs 102, the corresponding cell voltage values and the average cell temperature values are in a linear proportional relationship, and it can be understood that the cell voltage values and the average cell temperature values, which are acquired at each time within the preset time period, corresponding to each battery pack 102 are different, and therefore, in this embodiment, each battery pack 102 can determine the corresponding identification information according to the cell data of all the battery packs.
As can be seen from the above analysis, in the battery pack identification information distribution system provided in the embodiment of the present application, the controller sends the instruction for distributing the identification information to each battery pack connected in parallel, and after detecting the instruction for distributing the identification information, each battery pack respectively collects the corresponding battery cell data within the preset time period, and sends the corresponding battery cell data to all other battery packs connected in parallel; further, each battery pack determines corresponding identification information according to the cell data of all the battery packs. The method and the device realize that each battery pack determines the corresponding identification information according to the corresponding battery core data and the battery core data of all other battery packs which are connected in parallel with each other, and improve the efficiency and the accuracy of the distribution of the identification information of the battery packs.
Fig. 2 is a schematic structural view of any one of the battery packs 102 shown in fig. 1. As can be seen from fig. 2, any of the battery packs 102 in fig. 1 includes: a battery module 1021, and a battery identification information distribution module 1022.
The battery module 1021 comprises at least one battery unit 1022; it is understood that the battery pack may include one battery cell, and may also include a plurality of battery cells, and when the battery pack includes a plurality of battery cells, the plurality of battery cells are connected in series with each other to form the battery pack (the battery cells are not shown in fig. 2).
The battery identification information distribution module 1022 is configured to collect first electric core data of at least one battery cell 1022 within a preset time after detecting an instruction for distributing identification information.
It can be understood that, in this embodiment, each battery cell includes a battery cell, and in the battery pack working process of the battery cell, the cell voltage value and the average cell temperature value may change, and in this embodiment, the cell data includes a first cell voltage value, a second cell voltage value, and an average cell temperature value.
And sending the first battery core data to a target battery pack, wherein the target battery pack is the battery pack except for the battery core data in the at least two battery packs.
And determining the identification information of the battery pack according to the first battery cell data and the second battery cell data of the target battery pack within the preset time length.
As can be seen from the above analysis, in the battery pack provided in the embodiment of the present application, after the instruction for allocating the identification information is detected by the battery identification information allocation module, first battery core data of at least one battery cell of the battery pack within a preset time duration is acquired, and the first battery core data is sent to the target battery pack; further, according to the first electric core data and second electric core data of the target battery pack within the preset time length, identification information of the battery pack is determined. The identification information of any battery pack is determined by any battery pack according to the first battery core data corresponding to the battery pack and the second battery core data of all other battery packs connected with the battery pack in parallel, and the distribution efficiency and accuracy of the identification information of the battery packs are improved.
Fig. 3 is a flowchart illustrating an implementation of a method for allocating identification information of a battery pack according to a third embodiment of the present application. The present embodiment may be implemented by hardware or software of the battery pack 102 in the embodiment shown in fig. 2.
The details are as follows:

For example, the battery pack includes a single battery 1 and a single battery 2, where a first cell voltage value corresponding to the single battery 1 is 1v, a second cell voltage value is 1.2v, an average cell temperature value is 10 ℃, a first cell voltage value corresponding to the single battery 2 is 1.1v, a second cell voltage value is 1.5v, and an average cell temperature value is 11 ℃, then the first cell voltage value corresponding to the battery pack is 2.1v, the second cell voltage value is 2.7v, and the average cell temperature value is 10.5 ℃.
S302, the first battery core data is sent to a target battery pack, and the target battery pack is a battery pack of the at least two battery packs except for the battery core data.
And S303, determining the identification information of the battery pack according to the first battery cell data and the second battery cell data of the target battery pack.
It can be understood that, when the battery pack sends the first electric core data corresponding to the battery pack to all other battery packs connected in parallel with the battery pack, correspondingly, second electric core data sent by all other battery packs is received, because the electric core data of each battery pack includes the first electric core voltage value, the second electric core voltage value and the average electric core temperature value, it can be understood that the electric core temperature values of each battery are usually different, and the electric core voltage values are related to the electric core temperature values, therefore, the electric core data of each battery pack are different and can be used as a data basis for determining the identification information of the battery pack.
Specifically, as shown in fig. 4, it is a flowchart of a specific implementation of S303 in fig. 3. As can be seen from fig. 4, S303 includes S3031 to S3032. The details are as follows:
s3031, determining the serial number of the battery pack according to the first basic data and the second basic data of the target battery pack respectively.
It can be understood that the first basic data and the second basic data are formed by combining 16-system double-byte data corresponding to each numerical value according to a preset combination rule, for example, by sequentially arranging and combining a first cell voltage value, a second cell voltage value, and an average cell temperature value.
In this embodiment, the first basic data and the second basic data are arranged from small to large to obtain the arrangement sequence number value of the first basic data, where the arrangement sequence number value of the first basic data is the serial number of the battery pack.

Through the analysis, in the embodiment, the data packets are sequenced, the serial numbers corresponding to the data packets are identified as the identification information of the battery packets, and the distribution of the identification information of the battery packets is completed quickly and accurately.
Fig. 5 is a flowchart illustrating an implementation of a method for allocating identification information of a battery pack according to a fourth embodiment of the present application. As can be seen from fig. 5, compared with the embodiment shown in fig. 3, the difference between S501 and S301 in this embodiment is that S502 is further included before S503, and the specific implementation processes of S503 to S504 are different from those of S302 to S303, and it should be noted that S501 and S502 are in a sequential execution relationship. The details are as follows:
and S502, generating first basic data according to the first battery cell data, wherein the first basic data is a combined value of all numerical values of the first battery cell data.
It should be noted that the first cell data includes a first cell voltage value, a second cell voltage value, and an average cell temperature value of the battery pack within a preset time period. In this embodiment, the first cell voltage value, the second cell voltage value, and the average temperature value are combined according to a preset combination manner, so as to obtain a combination value of each value of the first cell data, where the combination value of each value is the first basic data.
S503, sending the first basic data to the target battery pack.
S504, according to the first basic data and the second electric core data of the target battery pack, identification information of the battery pack is determined.
It can be understood that, when any one of the battery packs combines the first electric core data to generate first basic data and sends the first basic data to all other battery packs connected in parallel with the any one of the battery packs, the any one of the battery packs simultaneously receives second basic data broadcasted by all other battery packs through a controller local area network communication bus, and after the any one of the battery packs receives the second basic data broadcasted by all other battery packs, the identification information of the any one of the battery packs is determined according to the first basic data and the second basic data of the any one of the battery packs.
As can be seen from the above analysis, in any battery pack in this embodiment, first basic data is generated by using first electric core data of the battery pack, the first basic data is sent to other battery packs juxtaposed to the battery pack, second basic data sent by all other battery packs is acquired, identification information of the battery pack is determined according to the first basic data and the second basic data, and efficiency and accuracy of battery pack identification information distribution are improved.
