Description

Technical Field

[0001] The present invention relates to the technical field of battery management, and in particular to a wireless battery management method, system and device based on beamforming. Background Art

[0002] Using power batteries as power has become the first choice for various electrical equipment such as automobiles and ships. Usually, power batteries are composed of multiple battery packs, which in turn contain several battery cells. During operation, it is often necessary to detect the working conditions of the battery cells in the battery pack, such as the temperature, pressure, and voltage of the battery cells. Therefore, a BMS (Battery Management System) is usually set up to achieve the above detection function.

[0003] In the BMS technical architecture, the corresponding data acquisition module and communication module need to be configured on the battery pack to collect the temperature, pressure, voltage and other information of the battery cells. The data acquisition module and communication module of each single battery are electrically connected through wiring harnesses, connectors, etc. This method of electrical connection through wiring harnesses, connectors, etc. not only occupies installation space but also increases weight, which will lead to low space utilization of the battery pack and reduced mileage of electrical equipment.

[0004] With the development of technology, wireless battery management systems are gradually developing to replace the wiring harness connection of traditional battery management systems. Wireless battery management systems are also called WBMS (Wireless Battery Management System, WBMS for short). In the WBMS technical architecture, each battery cell is still equipped with a data acquisition module, but each battery cell is connected in series through wireless communication technology, and no wiring harness is required. WBMS technology usually includes a BMU (Battery Monitor Unit) and a CMU (Cell Monitor Unit) that communicate with each other. In known technologies, BMU and CMU usually use omnidirectional antennas to communicate.

[0005] The advantage of an omnidirectional antenna is that it can transmit and receive signals evenly in all directions, thus being able to cover all CMU units; however, this omnidirectional communication method has significant disadvantages and technical difficulties. For example, omnidirectional antennas need to transmit signals at high power to ensure communication coverage of remote CMU units. Although this high-power transmission ensures the stability of communication, it greatly increases the power consumption of the system, affecting the system's energy efficiency and operating time.

[0006] Therefore, there is still an urgent need for a wireless battery management method that can reduce power consumption and increase operating time. Summary of the invention

[0007] The main purpose of the present invention is to propose a wireless battery management method, system and device based on beamforming to solve the problems of high power consumption and short operation time when the existing wireless battery management system uses omnidirectional antennas for communication.

[0052] The scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0054] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0055] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0056] To achieve the above object, the present invention proposes a wireless battery management method based on beamforming, which is used to establish communication between a BMU module and a CMU module. The wireless battery management method includes:

[0057] Step S110, the BMU module receives the location information sent by each CMU module, and divides the preset communication coverage area according to the location information, wherein the communication coverage area includes at least one CMU module;

[0058] Step S120, generating a directional signal for the communication coverage area, and sending the directional signal to each CMU module in the communication coverage area;

[0059] Step S130: establishing communication with the CMU module according to the directional signal response information fed back by the CMU module.

[0060] In some embodiments, reference Figure 1 , a wireless battery management method based on beamforming is used to establish communication between a BMU module and a CMU module. The BMU module first receives the location information sent by each CMU module, and then determines the location of each CMU module according to the location information of each CMU module. The locations of all CMU modules can form an area, and the BMU module can divide a preset communication coverage area in this area; wherein, there is at least one CMU module in the communication coverage area. The BMU module can generate a corresponding directional signal according to the location direction of each CMU module in the communication coverage area; at this time, the generated directional signal can be sent to each CMU module in the communication coverage area in a directional manner. For each CMU module located in the communication coverage area, when the CMU module receives the corresponding directional signal, it will respond to the directional signal, and then feedback the directional signal response information to the BMU module. The BMU module can establish communication with each CMU module in the communication coverage area according to the directional signal response information fed back by each CMU module.

[0061] It is understandable that in the embodiment of the present invention, there may be multiple preset communication coverage areas; the BMU module is equipped with an array antenna; the array antenna can generate corresponding directional signals for each communication coverage area. Beamforming is a wireless communication technology that is mainly used for directional transmission and reception of wireless signals to enhance signal strength in a specific direction while reducing interference in other directions. Beamforming adjusts the phase and amplitude of each antenna unit in the array antenna so that the transmitted or received signal is concentrated in a specific direction to form a narrow directional signal, thereby improving the gain and directivity of the signal.

[0062] Among them, refer to Figure 6, the wireless battery management system is used to manage the battery pack, and the wireless battery management system can be set inside the battery pack. The BMU array antenna is an array antenna built into the BMU module; Beamforming is beamforming; the RF signal coverage area is the preset communication coverage area, θ is the angle corresponding to the directional signal and the communication coverage area; CMU is the CMU module, where the dotted line between the CMU and the RF signal coverage area indicates that this part of the CMU is located in the pointed RF signal coverage area. The battery pack may include multiple battery cells, each of which has a built-in CMU module; the BMU module in the battery pack controls the battery cells corresponding to each CMU module separately through each CMU module. The BMU array antenna generates a directional signal of a corresponding angle for each RF signal coverage area according to Beamforming, and each directional signal can be sent to the CMU in the corresponding RF signal coverage area.

[0063] In this embodiment, the location information may be the coordinate information of the CMU module. For example, the spatial area within the battery pack may be represented by a spatial coordinate system; in this way, after each CMU module is installed in the battery pack, the coordinates may be used to represent the location of each CMU module. The BMU module receives the coordinate information sent by each CMU module, and then divides and classifies the coordinate information to obtain different spatial areas. One area may be selected from these spatial areas as the communication coverage area, so that a preset communication coverage area may be obtained. In another embodiment, multiple areas may also be selected from these spatial areas as the communication coverage areas, so that multiple preset communication coverage areas may be obtained. Of course, the location information may be other information that may represent the location of each CMU module.

[0064] In this embodiment, the array antenna in the BMU module is used to generate a directional signal. When the BMU module determines the communication coverage area, the BMU module can control the array antenna to generate a directional signal corresponding to the direction of the communication coverage area. In this way, the signal sent by the BMU module will only be sent to the communication coverage area in a direction and will not be sent to other areas. Unnecessary signal diffusion is reduced and communication efficiency is improved. In another embodiment, when the BMU module determines multiple communication coverage areas, the BMU module can also control the array antenna to generate a directional signal corresponding to the direction of each communication coverage area. In this way, the signal sent by the BMU module will only be sent to each communication coverage area in a direction and will not be sent to other areas in a disorderly manner. The BMU module only performs directional signal transmission in each designated communication coverage area, which reduces signal interference in each communication coverage area, avoids channel conflicts between CMU modules, and improves the communication reliability of the overall system.

[0065] In this embodiment, only the CMU module located in the communication coverage area will receive the directional signal; thus responding to the directional signal, it establishes communication with the BMU module. In this way, the CMU module will establish communication with the BMU module only when it is in the communication coverage area; when the CMU module is not in the communication coverage area, it will not establish communication with the BMU module. The power consumption of the CMU module in the non-communication coverage area is reduced, thereby reducing the power consumption of the system and extending the operating time of the system.

[0066] In some embodiments, the aforementioned wireless battery management method based on beamforming further includes:

[0067] Step S140, receiving a communication feedback signal sent by the CMU module, and acquiring a communication status between the BMU module and the CMU module according to the communication feedback signal;

[0068] Step S141, if the communication status is normal, the BMU module saves the corresponding information of the communication coverage area and the directional signal;

[0069] Step S142: If the communication status is abnormal, the BMU module adjusts the communication coverage area to obtain an updated communication coverage area, and generates a corresponding directional signal according to the updated communication coverage area.

[0070] In this embodiment, refer to Figure 2 After executing the aforementioned step S130, that is, when the CMU module in the communication coverage area establishes communication with the BMU module, the CMU module can perform directional communication with the BMU module. The CMU module sends a communication feedback signal to the BMU module, wherein the communication feedback signal can be used to determine whether the communication status between the BMU module and the CMU module is normal. The communication feedback signal may include information on whether the communication is interfered with and / or information on the strength of the communication signal, etc. After receiving the communication feedback signal, the BMU module analyzes the communication feedback signal (it may be determined by combining the information on whether the communication is interfered with and the information on the strength of the communication signal), thereby obtaining the communication status between the CMU module and the BMU module.

[0071] The BMU module can judge the communication status and determine whether the communication status is normal. The normal communication status can be that the communication between the CMU module and the BMU module is not disturbed; it can also be that the communication signal between the CMU module and the BMU module is strong; it can also be a combination of the two, etc.

[0072] If the BMU module determines that the communication status is normal, the BMU module will store the corresponding information of the communication coverage area and the directional signal. The corresponding information of the communication coverage area can be the location information of each CMU module located in the communication coverage area; the corresponding information of the directional signal can be the information used to generate the directional signal, such as: the phase and amplitude information of the directional signal. After the BMU module stores the corresponding information of the communication coverage area and the directional signal; if the wireless battery management system needs to be restarted during use, after the restart, the BMU module can quickly establish communication with the CMU module based on the stored corresponding information of the communication coverage area and the directional signal, thereby sending relevant instructions.

[0073] If the BMU module determines that the communication status is abnormal, the BMU module adjusts the communication coverage area to obtain an updated communication coverage area. For example, when the communication coverage area is initially divided, some CMU modules may be just at the edge of the communication coverage area. In this way, these CMU modules at the edge of the communication coverage area may be interfered by the CMU modules next to them that are not in the communication coverage area and / or the directional signal is not strong enough when sent to the edge of the communication coverage area; causing the communication status of these CMU modules at the edge of the communication coverage area to fail to meet the preset requirements. When the BMU module adjusts the communication coverage area, the range of the communication coverage area can be increased so that these CMU modules at the edge of the communication coverage area can be slightly away from the edge of the communication coverage area; thereby obtaining an updated communication coverage area. The BMU module generates corresponding directional signals according to the updated communication coverage area, so that these newly generated directional signals can meet the communication status requirements of the CMU modules in the middle area of ​​the communication coverage area while also meeting the communication status requirements of the CMU modules in the edge area of ​​the communication coverage area.

[0074] In some embodiments, the aforementioned wireless battery management method based on beamforming further includes:

[0075] Step S150, polling each CMU module until each CMU module feeds back corresponding position information;

[0076] Step S151: If the location information corresponding to the CMU module indicates that the CMU module is not in the communication coverage area, the CMU module is controlled to enter a dormant state.

[0077] Considering that the CMU module may not be able to communicate due to position change or other reasons, in this embodiment, refer to Figure 3After the BMU module establishes a communication connection with the CMU module, the BMU module polls each CMU module by sending a notification to obtain the latest location information of each CMU module, and timely distinguishes each CMU module into the CMU module in the communication coverage area and the CMU module not in the communication coverage area. The BMU module will control the CMU module not in the communication coverage area to enter the sleep state, thereby reducing unnecessary energy consumption and further reducing the power consumption of the system.

[0078] In some embodiments, the BMU module generates a directional signal for a communication coverage area and sends the directional signal to each CMU module in the communication coverage area, including:

[0079] Step S160, generating a corresponding directional beam according to the position information of the CMU module;

[0080] Step S161, sending a corresponding directional beam to each CMU module within the communication coverage area.

[0081] In this embodiment, refer to Figure 4 When executing the aforementioned step S120, the generated directional signal may be a directional beam, that is, the directional signal may be a directional beam that is concentratedly transmitted in a specific direction by the beamforming technology. For each CMU module in the communication coverage area; after knowing the location information of the CMU module, the direction of the directional beam can be adjusted according to the location information of the CMU module; so that the direction of the directional beam is aligned with the CMU module, and then when the directional beam is sent, it can be directed to the CMU module in the communication coverage area.

[0082] Among them, refer to Figure 7 , BMU is the BMU module, θ is the angle between the directional signal and the CMU module area; CMU is the CMU module; Figure 7 In the illustration, the CMUs are all within the communication coverage area. The BMU can generate a directional beam of a corresponding angle for each CMU, and each directional beam is sent to each corresponding CMU according to the corresponding angle.

[0083] In some embodiments, the BMU module includes a phase controller and an array antenna, the phase controller is used to adjust the phase and amplitude of the array antenna, and the BMU module generates a corresponding directional signal according to the updated communication coverage area, including:

[0084] Step S170, notifying the phase controller to work according to the updated communication coverage area to obtain an updated array antenna;

[0085] Step S171, controlling the updated array antenna to generate a new directional signal to cover the updated communication coverage area.

[0086] In this embodiment, refer to Figure 5When executing the aforementioned step S142, the phase and amplitude of the array antenna can be adjusted by the phase controller to generate a new directional signal, that is, the BMU module includes a phase controller and an array antenna, wherein the array antenna includes a plurality of antenna units. Each antenna unit can individually transmit a directional beam in a specific direction. Each antenna unit can be arranged in a linear arrangement or a rectangular arrangement, and the phase controller can individually adjust the phase and amplitude of each antenna unit. The phase controller adjusts the phase and amplitude of each antenna unit according to the updated position information of each CMU module in the communication coverage area. For example: the phase and amplitude of an antenna unit correspond to the position information of a CMU module. Thus, an updated array antenna is obtained; each antenna unit of the updated array antenna generates an updated directional beam according to the corresponding CMU module.

[0087] Among them, refer to Figure 8 The BMU module also includes a control unit; the control unit can be used to manage and coordinate the operation of the wireless battery management system. The control unit adjusts the phase and amplitude of each antenna unit through the phase controller to generate directional beams in all directions. The phase controller receives instructions from the control unit and converts these instructions into specific phases and amplitudes to adjust the corresponding antenna units.

[0088] In some other embodiments, before executing step S110, the method further includes:

[0089] The phase controller is notified to initialize the array antenna according to the array antenna initialization instruction to obtain an initialized array antenna.

[0090] In this embodiment, when the wireless battery management system is started, the BMU module generates an array antenna initialization instruction and sends it to the phase controller. The phase controller initializes and adjusts the phase and amplitude of each antenna unit according to the array antenna initialization instruction; for example: the phase controller can adjust the phase and amplitude of each antenna unit to be consistent, thereby obtaining the initial array antenna.

[0091] The present invention also proposes a wireless battery management system for establishing communication between a BMU module and a CMU module. The wireless battery management system includes:

[0092] The BMU module is used to receive the location information sent by each CMU module, divide the preset communication coverage area according to the location information, wherein the communication coverage area includes at least one CMU module; generate a directional signal for the communication coverage area, and send the directional signal to each CMU module in the communication coverage area; establish communication with the CMU module according to the directional signal response information fed back by the CMU module.

[0093] In some embodiments, the BMU module is further configured to:

[0094] Receive the communication feedback signal sent by the CMU module, and obtain the communication status between the BMU module and the CMU module according to the communication feedback signal;

[0095] If the communication status is normal, the corresponding information of the communication coverage area and the directional signal is saved;

[0096] If the communication state is abnormal, the communication coverage area is adjusted to obtain an updated communication coverage area, and a corresponding directional signal is generated according to the updated communication coverage area.

[0097] In some embodiments, the BMU module is further configured to:

[0098] Poll each CMU module until each CMU module feeds back corresponding location information;

[0099] If the location information corresponding to the CMU module indicates that the CMU module is not in the communication coverage area, the CMU module is controlled to enter a dormant state.

[0101] Notifying the phase controller to work according to the updated communication coverage area to obtain an updated array antenna;
