DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] The embodiment of the present application provides a battery balancing management method and system based on integration technology, the core of which is to integrate multiple sensors into the battery cells of the battery module, thereby obtaining the electrical parameter data of each battery cell in the battery module during charging and discharging; determine the battery state of charge of each battery cell in the battery module according to the corresponding electrical parameter data, determine the charge energy level of the battery module and the charge energy level of each battery module in the battery module according to the battery state of charge of each battery cell; use the charge energy level of the battery module to determine the module charge balancing domain, perform balancing judgment through the module charge balancing domain and the charge energy level of each battery module in the battery module, pair and balance each battery module in the battery module based on the balancing judgment result, and then complete the balancing management of the battery module. The above scheme can be used to efficiently manage the battery cells in the battery module to improve the overall performance of the battery module.

[0022] Embodiment 1: In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 As shown in FIG. 1 , this figure is an exemplary flow chart of a battery balancing management method based on integrated technology according to this embodiment of the present application. The management method includes the following steps: In step S1, a variety of sensors are integrated into battery cells of a battery module, thereby obtaining electrical parameter data of each battery cell in the battery module during charging and discharging.

[0023] In specific implementation, multiple sensors can be integrated into the battery cells of the battery module through integration technology; the core of the integration technology is to integrate multiple sensors into each battery cell through a compact design. The selection of these sensors depends on the electrical parameters to be monitored. The sensors integrated in this application include voltage sensors, current sensors, and temperature sensors; it should be noted that in order to integrate multiple sensors into a single battery cell, miniaturized and integrated sensor components are usually used. For example, miniaturized sensors manufactured using MEMS (micro-electromechanical system) technology are not only small in size and light in weight, but also have the characteristics of high precision and low power consumption. Through advanced packaging technology, these sensors can be tightly integrated inside the battery module to ensure that they can work stably in harsh working environments.

[0024] In this embodiment, the electrical parameter data of each battery cell in the battery module during charging and discharging can be obtained through the integrated sensor; it should be noted that, in this application, the electrical parameter data includes the current data, voltage data and battery temperature data of the battery cell.

[0025] In step S2, the battery state of charge of each battery cell in the battery module is determined according to the corresponding electrical parameter data, and the charge energy level of the battery module and the charge energy level of each battery module in the battery module are determined according to the battery state of charge of each battery cell.

[0026] In this embodiment, the battery charge state of each battery cell in the battery module can be determined according to the corresponding electrical parameter data in the following manner, namely: Build a battery cell model; For each battery cell in the battery module, the electrical parameter data of the battery cell is input into the battery cell model for estimation to obtain the battery state of charge of the battery cell, and then the battery state of charge of each battery cell in the battery module is obtained.

[0027] In the specific implementation, first, a battery cell model can be constructed, which is a circuit equivalent model of the battery cell. The battery cell model is usually composed of a voltage source, a series resistor and a parallel capacitor of the single cell, and is used to describe the dynamic electrical behavior of the single cell. The battery cell model can be constructed by existing technologies and will not be repeated here; then, for each battery cell in the battery module, the electrical parameter data of the battery cell can be input into the battery cell model for estimation, that is, the current data, voltage data and battery temperature data of the battery cell are input into the battery cell model for battery state of charge estimation, so that the battery state of charge of the battery cell can be obtained, wherein the battery state of charge represents the ratio between the current remaining power of the battery cell and the maximum available power of the battery cell. The battery state of charge of each battery cell in the battery module can be obtained in the above manner.

[0028] Preferably, in this embodiment, the charge energy level of the battery module and the charge energy level of each battery module in the battery module are determined according to the battery charge state of each battery cell, referring to Figure 2 As described, the figure is a schematic diagram of a process for determining the charged energy level of a battery module and the charged energy level of each battery module in the battery module in some embodiments of the present application. In this embodiment, determining the charged energy level of the battery module and the charged energy level of each battery module in the battery module can be implemented by the following steps: First, in step S21, the charge energy of each battery cell in the battery module is determined according to the corresponding battery charge state; Then, in step S22, the charge energy level of the battery module is determined by the charge energy of all battery cells; Next, in step S23, the battery module is divided into a plurality of battery modules; Finally, in step S24, for each battery module in the battery module, the charged energy level of the battery module is determined by the charged energy of all battery cells in the battery module, thereby obtaining the charged energy level of each battery module in the battery module.

[0029] In specific implementation, first, the charged energy of each battery cell in the battery module can be determined according to the corresponding battery state of charge, wherein the charged energy is an indicator for measuring the amount of energy carried by the corresponding battery cell, and the voltage and capacity of the battery cell can be obtained. The capacity of the battery cell can be obtained through the table provided by the battery manufacturer, and the product of the battery state of charge, voltage and capacity of the battery cell is used as the charged energy of the battery cell. The charged energy of each battery cell in the battery module can be obtained in the above manner; then, the charged energy level of the battery module can be determined through the charged energy of all battery cells, wherein the charged energy level is an indicator for indicating the amount of energy contained, and the sum of the charged energies of all battery cells can be used as the charged energy level of the battery module.

[0030] In addition, in the specific implementation, the battery module can be divided into multiple battery modules. The battery module is divided into several battery modules for easy management and maintenance. Each battery module is composed of multiple battery cells. The power management of the battery module is crucial to the balance and performance of the battery module. The battery modules can be divided according to the number of battery cells, that is, each battery module contains a fixed number of battery cells. It should be noted that in the present application, the number of battery cells contained in the battery module is an even number; then, for each battery module in the battery module, the charged energy level of the battery module can be determined by the charged energy of all the battery cells in the battery module, that is, the sum of the charged energies of all the battery cells in the battery module is taken as the charged energy level of the battery module. The charged energy level of each battery module in the battery module can be obtained in the above manner.

[0031] It should be noted that accurate battery balancing management can be achieved by determining the battery state of charge of the battery cell based on the electrical parameter data, and further calculating the charge energy level of the battery module and each battery module based on the battery state of charge. This can not only improve the overall performance of the battery module, extend the battery life, and improve energy utilization, but also enhance the safety, reliability and intelligence level of the battery system.

[0032] In step S3, the module charge balancing domain is determined using the charge energy level of the battery module, and a balancing judgment is performed through the module charge balancing domain and the charge energy level of each battery module in the battery module. Based on the balancing judgment result, each battery module in the battery module is paired and balanced, thereby completing the balancing management of the battery module.

[0033] In this embodiment, the charge energy level determination module charge balancing domain of the battery module may be specifically implemented in the following manner, namely: Obtaining a preset charge equalization threshold; A module charge balancing domain is determined according to the charge energy level of the battery module and the charge balancing threshold.

[0034] In specific implementation, first, a preset charge balancing threshold value can be obtained. The charge balancing threshold value is a value used to control the range and accuracy of the module charge balancing domain. It can be preset through historical experiments and will not be repeated here. Then, the module charge balancing domain can be determined according to the charge energy level and charge balancing threshold of the battery module. The module charge balancing domain is a data domain used to determine whether the battery module has achieved charge balancing. The sum of the charge energy level of the battery module and the charge balancing threshold value can be used as the upper limit of the module charge balancing domain, and the difference between the charge energy level of the battery module and the charge balancing threshold value can be used as the lower limit of the module charge balancing domain, thereby obtaining the module charge balancing domain.

[0035] In this embodiment, the balancing determination is performed through the module charge balancing domain and the charge energy level of each battery module in the battery module to determine whether the charge energy level of each battery module in the battery module is within the module charge balancing domain.

[0036] Preferably, in this embodiment, each battery module in the battery module is paired and balanced based on the balance determination result, referring to Figure 3 The figure is a schematic diagram of the process of pairing and balancing in some embodiments of the present application. In this embodiment, pairing and balancing can be implemented by the following steps: First, in step S31, when the balancing determination result is that the charge energy levels of all battery modules in the battery module are within the module charge balancing domain, the charge energy pairing balancing is not performed on the battery modules in the battery module; Then, in step S32, when the balancing determination result is that there is a battery module in the battery module whose charge energy level is not within the module charge balancing domain, charge energy pairing and balancing are performed on each battery module in the battery module.

[0037] In specific implementation, when the balancing judgment result is that the charge energy levels of all battery modules in the battery module are within the module charge balancing domain, it indicates that there is no charge imbalance between the battery modules in the battery module, all battery modules in the battery module have reached a balanced state, and the charge energy difference between the battery modules is within an acceptable range, then charge energy pairing and balancing of the battery modules in the battery module is not performed; when the balancing judgment result is that the charge energy level of a battery module in the battery module is not within the module charge balancing domain, it indicates that there is a charge imbalance between the battery modules in the battery module, all battery modules in the battery module have not reached a balanced state, and the charge energy difference between the battery modules is not within an acceptable range, then charge energy pairing and balancing of the battery modules in the battery module is required.

[0038] In this embodiment, the charge energy pairing and balancing of each battery module in the battery module may be performed in the following manner, namely: Sorting the battery modules in the battery module according to the charge energy level to obtain a battery module sequence; Pairing the battery module sequence head to tail to obtain a plurality of battery module pairs; The charge energy is balanced for each battery module pair.

[0039] In specific implementation, first, each battery module in the battery module can be sorted in descending order according to the charge energy level, so as to obtain a battery module sequence; then, the battery module sequence can be paired head to tail, that is, the first battery module in the battery module sequence and the penultimate battery module sequence are regarded as a battery module pair, and the second battery module and the penultimate battery module sequence are regarded as a battery module pair, so as to obtain multiple battery module pairs; finally, each battery module pair can be charged and balanced, that is, the difference in charge energy level between the two battery modules in the battery module pair is reduced to a minimum, so that their load states are close. In actual implementation, the electric energy of the battery module with a high charge energy level can be transferred to the battery module with a low charge energy level through the current regulation system, until the difference in charge energy level between the two battery modules is reduced to a minimum. The charge energy balancing of each battery module pair can be completed in the above manner.

[0040] It should be noted that when pairing the battery module sequence head to tail, there may be an unpaired battery module. In the present application, the charge energy of the battery module is balanced, that is, all the battery cells in the battery module are sorted in descending order according to the size of the charge energy, and the battery cells in the obtained battery cell sequence are paired in pairs to achieve charge energy balance.

[0041] In addition, it should be noted that by using the charge energy level of the battery module to determine the module charge balancing domain, and pairing and balancing the battery modules based on the balancing judgment results, the charge energy of each battery module in the battery module can be maintained in a relatively balanced range with other modules, which can not only significantly improve the performance and life of the battery module, but also enhance the intelligence, safety and efficiency of the battery management system.

[0042] It can be seen that in the present application, firstly, by integrating a variety of sensors into the battery cells of the battery module through integration technology, the monitoring accuracy and intelligence level of the battery management system can be effectively improved, thereby improving the performance of the battery, extending the service life and ensuring safety; then, by determining the battery state of charge of the battery cell based on the electrical parameter data, and further inferring the charge energy level of the battery module and each battery module based on the battery state of charge, accurate battery balancing management can be achieved; finally, by determining the module charge balancing domain using the charge energy level of the battery module, and pairing and balancing the battery modules based on the balancing judgment result, the charge energy of each battery module in the battery module can be kept in a relatively balanced range with other modules, which can not only significantly improve the performance and life of the battery module, but also enhance the intelligence, safety and efficiency of the battery management system.

[0043] In summary, the technical solution adopted in the present application can efficiently perform balanced management on the battery cells in the battery module to improve the overall performance of the battery module.
