Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a battery pack assembly for a vehicle and a vehicle. Background Technology

[0002] In related technologies, temperature monitoring of power battery packs typically uses negative temperature coefficient thermistors as sensors, usually located above the cell top cover. However, this design has significant drawbacks. The sensor is usually covered by structural components such as brackets and module covers, physically blocking the direct heat exchange path between the sensor and the internal space of the battery pack. This significantly reduces heat conduction efficiency, resulting in a deviation of more than 20% between the measured temperature of the internal space detected by the sensor and the actual internal temperature. The thermal hysteresis effect can cause the battery management system to fail to trigger the fuse protection or cooling system in time, potentially missing the optimal thermal intervention window. Therefore, improving the detection sensitivity of the temperature sensor is the technical problem that this application aims to solve. Utility Model Content

[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] The following is for reference. Figures 1-3 A battery pack assembly 100 for a vehicle is described according to an embodiment of this application.

[0036] According to an embodiment of this application, a battery pack assembly 100 for a vehicle includes a temperature sensor 1 and a module cover 2. The temperature sensor 1 is provided with a first detection surface and a second detection surface. The first detection surface is adapted to be connected to a battery cell 101 for detecting the temperature of the battery cell 101. The second detection surface is located on the side away from the battery cell 101. The module cover 2 is adapted to cover the top of the battery module and is directly opposite to the second detection surface. The module cover 2 is provided with a first through hole 21, the position of which corresponds to the second detection surface. The second detection surface is adapted to open towards the internal space of the battery pack assembly 100 through the first through hole 21 to collect the temperature of the internal space of the battery pack assembly 100.

[0037] In related technologies, the temperature sensor 1 is covered by structural components such as the module cover, which obstructs the heat exchange path with the internal space of the battery pack assembly 100, resulting in a large deviation between the temperature detected by the temperature sensor 1 and the actual temperature.

[0038] It should be noted that multiple battery cells 101 are arranged and connected in sequence to form a battery module, and multiple battery modules are arranged and connected in sequence to form a battery pack.

[0039] According to an embodiment of this application, a battery pack assembly 100 for a vehicle includes a temperature sensor 1 and a module cover 2. The temperature sensor 1 has a first detection surface and a second detection surface. The first detection surface is directly connected to the battery cell 101 and can detect the temperature generated by the battery cell 101 itself. The second detection surface is located on the side away from the battery cell 101, and a first through hole 21 is opened at a corresponding position on the module cover 2. The second detection surface directly faces the internal space of the battery pack assembly 100 through the first through hole 21, avoiding the problem of low heat conduction efficiency and easy distortion caused by the sensor being blocked by structural components and heat having to be conducted through layers to reach the sensor. The second detection surface is directly connected to the internal space of the battery pack, and heat does not need to be further... Through structural conduction, the heat inside the battery pack can be rapidly and directly exchanged with the second detection surface. The smooth heat exchange allows the temperature sensor 1 to more quickly detect subtle changes in the temperature inside the battery pack. When the temperature inside the battery pack fluctuates due to charging and discharging processes, the second detection surface can detect it immediately and transmit the information to the sensor in a timely manner, reducing the time delay and heat loss of heat conduction. This improves the sensor's response speed and detection accuracy to temperature changes. Combining the working methods of the first and second detection surfaces, especially the heat exchange advantage brought by the direct connection between the second detection surface and the inside of the battery pack, the detection sensitivity of the temperature sensor 1 can be significantly improved.

[0040] The battery pack assembly 100 for a vehicle according to some embodiments of this application further includes a temperature sensor bracket 3, which is configured as an annular frame. An accommodating space 31 suitable for accommodating a temperature sensor 1 is formed within the annular frame. The inner wall of the annular frame is at least partially fitted to the temperature sensor 1 to provide at least partial abutment against the outer periphery of the temperature sensor 1.

[0041] The temperature sensor bracket 3 is constructed as a ring frame, forming an internal space to accommodate the temperature sensor 1, providing precise positioning for the temperature sensor 1. Since the inner wall of the ring frame is at least partially in contact with the temperature sensor 1, even during vehicle operation and encountering complex conditions such as bumps and vibrations, the sensor is confined within this space 31 and will not deviate from its original detection position due to shaking, thus avoiding affecting the accuracy of temperature detection of the battery cell 101 and the internal space of the battery pack. The ring frame at least partially abuts the outer periphery of the temperature sensor 1, firmly mounting the temperature sensor 1 within the ring frame bracket, making the sensor and other parts of the battery pack form a more stable whole. When the vehicle accelerates, decelerates, or turns, the internal components of the battery pack are affected by inertial forces. The temperature sensor bracket 3 can effectively disperse these external forces on the sensor, preventing damage due to uneven stress, extending the service life of the temperature sensor 1, and thus ensuring the long-term stable operation of the battery pack assembly 100, improving the reliability and durability of the vehicle battery system.

[0042] According to some embodiments of this application, a battery pack assembly 100 for a vehicle further includes a reinforcing plate 4, which covers at least a portion of the second detection surface; wherein the reinforcing plate 4 is provided with a second through hole 41, the position of the second through hole 41 is directly opposite to the second detection surface, and the second detection surface is adapted to open toward the internal space of the battery pack assembly 100 through the second through hole 41.

[0043] Temperature sensor 1 needs to operate stably and reliably in battery pack assembly 100. Due to the complex internal environment of the battery pack, there may be various vibrations, impacts, and slight deformations during battery charging and discharging. Reinforcing plate 4 covers at least part of the second detection surface, providing additional structural support for temperature sensor 1, dispersing the stress caused by vibration, and enabling temperature sensor 1 to maintain its original shape and structural integrity, thereby stably performing its temperature detection function. The reinforcing plate 4 is provided with a second through hole 41, and the position of the second through hole 41 is directly opposite to the second detection surface. The second detection surface is open to the internal space of battery pack assembly 100 through the second through hole 41, ensuring that the path of temperature sensor 1 for temperature detection is not affected. Although the reinforcing plate 4 covers part of the second detection surface, the second through hole 41 is aligned with the detection surface, allowing the heat inside the battery pack to be smoothly transferred to the second detection surface through the through hole.

[0044] According to some embodiments of this application, the battery pack assembly 100 for a vehicle further includes a data acquisition plate 5, which is disposed between the module cover plate 2 and the battery module, and the data acquisition plate 5 has a clearance notch 51 for avoiding the temperature sensor 1.

[0045] The acquisition plate 5 is positioned between the module cover plate 2 and the battery module, and a clearance notch 51 is formed on it to avoid the temperature sensor 1. This clearance notch 51 provides a precise positional reference for the installation of the temperature sensor 1. During the assembly of the battery pack assembly 100, the temperature sensor 1 can be accurately placed in the appropriate position based on the position of the clearance notch 51, avoiding the problem of inaccurate temperature detection caused by installation position deviation. At the same time, it makes the layout of the battery pack assembly 100 more reasonable. The acquisition plate 5 is positioned between the module cover plate 2 and the battery module, and the clearance notch 51 accommodates the temperature sensor 1, making full use of the internal space of the battery pack, reducing space waste between components, and improving the overall integration of the battery pack assembly 100.

[0046] In some embodiments of this application, the acquisition board 5 is constructed as a flexible circuit board.

[0047] According to some embodiments of this application, a battery pack assembly 100 for a vehicle has a data acquisition plate 5 having a connecting segment 52 disposed in an avoidance notch 51. The data acquisition plate 5 is communicatively connected to a temperature sensor 1 through the connecting segment 52. The connecting segment 52 is located between the temperature sensor bracket 3 and the reinforcing plate 4. The connecting segment 52 is adapted to transmit the temperature signal acquired by the temperature sensor 1.

[0048] A connecting segment 52 is formed on the acquisition board 5, located at the clearance notch 51. This connecting segment 52 is communicatively connected to the temperature sensor 1, allowing the temperature signal acquired by the temperature sensor 1 to be directly transmitted to the acquisition board 5. The connecting segment 52 is located between the temperature sensor bracket 3 and the reinforcing plate 4, providing good protection for it. The temperature sensor bracket 3 and the reinforcing plate 4 effectively block external physical interference, such as vibration and collisions, from affecting the connecting segment 52. When the vehicle encounters bumps during driving, the battery pack will vibrate, potentially causing the connection to loosen or be damaged, thus affecting the transmission of the temperature signal. In this structure, the connecting segment 52 is placed between the bracket and the reinforcing plate 4, reducing this risk and ensuring the stability and reliability of the temperature signal transmission.

[0049] According to some embodiments of this application, a battery pack assembly 100 for a vehicle includes a connecting segment 52 comprising a first connecting segment 521 and a second connecting segment 522. One end of the first connecting segment 521 is connected to the edge of a clearance notch 51, and the other end of the first connecting segment 521 is connected to one end of the second connecting segment 522. The other end of the second connecting segment 522 is connected to a temperature sensor 1. The second connecting segment 522 is disposed between a temperature sensor bracket 3 and a reinforcing plate 4. A first gap 5211 is formed between the first connecting segment 521 and at least a portion of the clearance notch 51, and a second gap 5221 is formed between the second connecting segment 522 and at least a portion of the clearance notch 51. The size of the first gap 5211 is larger than the size of the second gap 5221.

[0050] The connecting segment 52 includes a first connecting segment 521 and a second connecting segment 522. One end of the first connecting segment 521 is connected to the edge of the clearance notch 51, and the other end is connected to the second connecting segment 522. The second connecting segment 522 is then connected to the temperature sensor 1. During the assembly of the battery pack assembly 100, there may be certain errors in the manufacturing and installation of various components. The segmented connecting segment 52 can adapt to these errors by bending and adjusting itself, ensuring accurate connection with the temperature sensor 1. At the same time, when the battery pack is subjected to vibration or other external forces during vehicle operation, the segmented structure of the connecting segment 52 can better disperse stress and avoid damage to the connecting segment 52 due to stress concentration. A first gap 5211 is formed between the first connecting segment 521 and at least part of the clearance notch 51, and the size of the first gap 5211 is larger than the size of the second gap 5221. A second gap 5221 is formed between the second connecting segment 522 and at least part of the clearance notch 51. Such a gap ensures the normal operation of the connecting section 52 while optimizing the spatial layout of the battery pack assembly 100; the larger first gap 5211 provides a certain amount of room for the first connecting section 521 to move, so that the first connecting section 521 can have a certain buffer when subjected to external force, reducing the impact on the acquisition board 5 and other components. The gap setting also avoids friction and interference between the connecting section 52 and the edge of the clearance notch 51, improving the reliability of the entire battery pack assembly 100.

[0051] According to some embodiments of this application, a battery pack assembly 100 for a vehicle further includes a blister tray 6 and a fixing part 7. The blister tray 6 is disposed between the acquisition plate 5 and the battery module, or between the acquisition plate 5 and the module cover plate 2. The fixing part 7 passes through the reinforcing plate 4, the acquisition plate 5 and the temperature sensor bracket 3, and is adapted to be heat-pressed to the blister tray 6.

[0052] The blister pack 6 is positioned between the acquisition plate 5 and the battery module, or between the acquisition plate 5 and the module cover 2, serving as a buffer and support. When the vehicle vibrates or is impacted by external forces during operation, the blister pack 6 can absorb some energy, reducing the direct impact on the acquisition plate 5, battery module, and other components. When the vehicle travels over bumpy roads, the blister pack 6 can alleviate the vibration transmission between the battery module and the acquisition plate 5, preventing components from loosening or being damaged due to vibration. The fixing part 7 passes through the reinforcing plate 4, the acquisition plate 5, and the temperature sensor bracket 3, and is hot-pressed to the blister pack 6, firmly connecting these components together. This makes the entire battery pack assembly 100 form a tighter overall structure, effectively fixing the relative positions of each component, reducing displacement and shaking between components, and further improving the structural stability of the battery pack assembly 100 under complex working conditions. The fixing effect of the fixing part 7 and the blister pack 6 ensures that each component remains relatively stable and does not misalign or separate.

[0053] In some embodiments of this application, the fixing part 7 is constructed as two hot-riveted pillars, through which the reinforcing plate 4, the acquisition plate 5 and the temperature sensor bracket 3 are respectively inserted, and hot-pressed to the blister tray 6.

[0054] According to some embodiments of this application, a battery pack assembly 100 for a vehicle has a module cover 2 with a plurality of first through holes 21 arranged in a centrally symmetrical manner about the geometric center of the module cover 2, wherein at least one first through hole 21 is provided corresponding to a second detection surface.

[0055] In related technologies, the module cover 2 requires differentiation of its front and back, as well as its front and back orientation, during installation. Incorrect orientation not only hinders installation but can also damage the cover and related components. Subsequent rework and correction consume significant manpower, resources, and time. The first through hole 21 on the module cover 2 is centrally symmetrical about its geometric center. This simplifies the assembly process of the battery pack assembly 100, eliminating the need to meticulously distinguish the front and back orientation of the cover during installation. This eliminates the need for complex error-proofing measures during assembly. This mechanism reduces potential problems caused by incorrect installation orientation and significantly improves assembly efficiency. Simultaneously, the centrally symmetrical arrangement of the first through-hole 21 on the module cover 2 about its geometric center enhances its versatility. In different battery pack models, as long as the centrally symmetrical design principle of the first through-hole 21 is followed, the module cover 2 produced in the same batch can be used in various assembly scenarios. Regardless of differences in battery pack size or internal structure layout, as long as the basic thermal management requirements and the setting method of the temperature sensor 1 remain consistent, the module cover 2 can achieve universality. This not only reduces the workload of designing and producing specific module covers 2 for different products, lowering mold development costs, but also makes inventory management more convenient and efficient, eliminating the need to maintain large inventories for different specifications of covers, further optimizing the company's production and operating costs.

[0056] According to some embodiments of this application, in a battery pack assembly 100 for a vehicle, temperature sensors 1 are configured as a plurality of spaced-apart sensors on the battery module.

[0057] Temperature sensors 1 are configured to be spaced out on the battery module. During operation, due to individual differences in the cells 101 and uneven distribution of charging and discharging current, the temperature of different parts of the battery module may vary significantly. Multiple temperature sensors 1 spaced out can monitor the temperature of different areas of the battery module separately. By spaced out the temperature sensors 1 at different locations, the temperature distribution of the entire battery module can be captured more comprehensively, avoiding the situation where temperature anomalies in some areas are overlooked due to relying on only a single sensor. This significantly improves the comprehensiveness of temperature monitoring. Comprehensive monitoring makes the acquired temperature data more accurate, providing more accurate information to the battery management system and helping it make more precise thermal management decisions.

[0058] The vehicle according to an embodiment of this application is briefly described below.

[0059] The vehicle according to the embodiments of this application includes the battery pack assembly 100 of any of the above embodiments. Since the vehicle according to this embodiment is equipped with the battery pack assembly 100 of any of the above embodiments, the vehicle according to this application has a temperature sensor 1 with improved sensitivity, enabling more timely detection of temperature changes inside the battery pack. When the temperature abnormally rises or falls, the battery management system can promptly trigger thermal management measures such as fuse protection or cooling systems based on the accurate temperature information provided by the sensor, effectively preventing safety accidents caused by overheating or overcooling of the battery, thereby significantly improving the safety of the vehicle battery. Through the accurate monitoring and timely feedback of the battery pack temperature by the temperature sensor 1, the vehicle's thermal management system can control the battery pack temperature within a suitable range. This avoids performance degradation and shortened lifespan of the battery due to prolonged exposure to excessively high or low temperature environments, helping to extend the battery's cycle life and reduce vehicle operating costs.
