For example, in urban traffic congestion, such as morning and evening peak commuting, the vehicle needs to be frequently started and stopped, and the battery pack needs to have high power density and instantaneous response capability to efficiently handle frequent acceleration, braking and regenerative energy recovery, as well as rapid charging and discharging capability; while driving on long-distance highways, more attention is paid to the high energy density of the battery pack to ensure the endurance mileage of the automobile.

[0004] If only high power density or high energy density is considered, both are easy to lead to low energy utilization rate and serious performance degradation of the battery pack. Therefore, how to meet the performance requirements of the battery pack under different driving conditions during vehicle driving has become the core problem of the current automobile battery pack research and development.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application provides an adaptive variable module layout automotive battery pack structure, which can solve the problem in related technologies where the battery pack cannot be dynamically adjusted according to different road conditions, resulting in low energy utilization and severe performance degradation of the battery pack.

[0023] Reference Figure 1 and Figure 2 This application provides an adaptive variable module layout automotive battery pack structure, which includes a battery housing 1, a power module 2, an energy module 3, a moving mechanism 4, and a control mechanism. The battery housing 1 houses the battery pack body. The power module 2 and the energy module 3 are spaced apart and positioned on the same end face of the battery housing 1. The power module 2 is used to handle high-power demands during vehicle start-up and acceleration, while the energy module 3 provides stable energy output for long-distance driving. The moving mechanism 4 is connected to the battery pack body and slidably mounted on the end face of the battery housing 1 where the power module 2 and the energy module 3 are located. The moving mechanism 4 has a first position, a second position, and a third position. When the moving mechanism 4 is in the first position, it is connected to the power module 2, which in turn connects to the battery pack body, supplying power to the battery pack body. When the moving mechanism 4 is in the second position, it is connected to the energy module 3, which in turn connects to the battery pack body, supplying power to the battery pack body. When the moving mechanism 4 is in the third position, it connects both the power module 2 and the energy module 3, allowing both modules to simultaneously supply power to the battery pack body, thereby reducing their energy consumption and achieving an energy-saving mode. The control mechanism is connected to both the battery pack body and the moving mechanism 4, and is used to detect the vehicle's driving status. Based on the vehicle's driving status, it switches the position of the moving mechanism 4, enabling the battery pack to automatically adjust its operating mode according to the vehicle's driving status.

[0024] When the vehicle is in congested urban traffic, the control mechanism detects frequent starts and stops. At this time, the control mechanism switches the moving mechanism 4 to the first position, connecting the battery pack to the power module 2, enabling the battery pack to quickly charge and discharge, meeting the needs of frequent starts and stops. When the vehicle is traveling long distances at high speeds, the control mechanism detects continuous high-speed travel and switches the moving mechanism 4 to the second position, connecting the battery pack to the energy module 3, providing stable energy output and extending the driving range. When the vehicle is traveling short distances and needs to balance performance and energy consumption, the control mechanism switches the moving mechanism 4 to the third position, connecting the battery pack to both the power module 2 and the energy module 3, achieving low-power operation and dynamically adjusting according to different road conditions. This significantly improves the energy utilization rate of the battery pack and reduces the risk of performance degradation. This solves the technical problem of how to meet the battery pack performance requirements under different driving conditions during vehicle operation.

[0025] More specifically, vehicle driving status includes vehicle speed, acceleration, remaining battery charge, and battery temperature. During actual installation, the control mechanism connects to the vehicle control system and receives information on vehicle speed, acceleration, remaining battery charge, and battery temperature. The control mechanism has pre-set thresholds for each data point, and by comprehensively analyzing these parameters, it can determine the vehicle's current driving condition and thus switch the position of the moving mechanism 4 accordingly. For example, by detecting vehicle speed and acceleration, it can determine whether the vehicle is in congested urban traffic or traveling at high speed; by detecting remaining battery charge and temperature, it can determine the battery's health status and operating conditions, ensuring the battery pack operates safely and efficiently under various conditions, further improving the battery pack's adaptability and energy utilization efficiency.

[0026] In one embodiment of this application, a grid-like slide rail 11 is provided on the battery housing 1 to form a multi-directional guide rail network on the surface of the battery housing 1, providing all-round positioning and movement support for the moving mechanism 4, significantly enhancing the flexibility and reconfigurability of the internal module layout of the automotive battery pack. The battery housing 1 is precision-manufactured using high wear-resistant alloy materials to enhance its structural strength and extend its service life. For example, high-chromium cast iron, maraging steel, tungsten carbide-based cemented carbide, nickel-based alloys, and aluminum bronze alloys are used. In the initial material selection, high-chromium cast iron, with its high chromium content forming a carbide strengthening phase, combines hardness and toughness; maraging steel has ultra-high strength and fatigue resistance; tungsten carbide-based cemented carbide is known for its extremely high hardness and high-temperature resistance; nickel-based alloys perform well in high-temperature and corrosive media; and aluminum bronze alloys have excellent self-lubricating and antistatic properties.

[0027] In the early stages of manufacturing the battery housing 1, the selection of materials must match the requirements of dynamic operating conditions. For example, high-chromium cast iron provides basic wear resistance, effectively coping with the high-frequency start-stop vibrations under urban congestion conditions; tungsten carbide-based hard alloys ensure the positioning accuracy and low-friction operation of the moving mechanism 4 when sliding on the battery housing 1; aluminum bronze alloys can balance wear resistance and compatibility with electronic devices, avoiding electrostatic interference. In actual manufacturing, the battery housing 1 and the slide rail 11 can be integrally manufactured to reduce subsequent additional assembly and welding processes. This integrated design not only reduces the potential risks of structural stress concentration, thermal deformation, and reduced sealing caused by welding joints, but also significantly improves the overall rigidity and durability between the battery housing 1 and the slide rail 11, ensuring the sliding positioning performance of the moving mechanism 4 is maintained under long-term vehicle vibration and complex road conditions. At the same time, integrated manufacturing simplifies the production process, reduces the number of parts, assembly steps, and manual intervention, effectively reducing the risk of quality fluctuations during the manufacturing process.

[0028] Reference Figure 3 The moving mechanism 4 includes a moving housing 41 and a position detection component. The moving housing 41 has a slider 411, which slides on a slide rail 11. The moving housing 41 is electrically connected to the battery pack body. Both the power module 2 and the energy module 3 have a first electrical connection terminal 211. The moving housing 41 has a second electrical connection terminal 412 for connecting to the first electrical connection terminal 211. The control mechanism connects to the moving housing 41 wirelessly and can drive the moving housing 41 to move along the slide rail 11 via the slider 411, thereby switching the position of the moving housing 41. The design of the first electrical connection terminal 211 and the second electrical connection terminal 412 ensures reliable and stable electrical connection or disconnection between the moving housing 41 and the power module 2 and energy module 3, ensuring the quality of electrical connection when switching between different positions and improving overall reliability and service life. The position detection component is connected to the control mechanism and is used to detect the position status of the moving housing 41, allowing the control mechanism to determine the current position of the moving housing 41.

[0029] Furthermore, the position detection component includes positioning chips 13. In this embodiment, multiple positioning chips 13 are provided, all of which are disposed within the slide rail 11 and connected to the control mechanism. These multiple positioning chips 13 can detect the position of the moving mechanism 4 in real time and provide accurate position feedback to the control mechanism, ensuring that the control mechanism can accurately switch the first, second, and third positions of the moving mechanism 4. This mechanism of collaborative detection by multiple positioning chips 13 not only eliminates the risk of single-point failure but also significantly improves the anti-interference capability of the positioning chips 13 in complex environments such as vehicle vibration and temperature fluctuations, thereby ensuring the position accuracy and response speed of the moving mechanism 4 during the switching process and providing users with a more stable and safer user experience.

[0030] Furthermore, to further achieve precise positioning and secure locking of the moving mechanism 4 after position switching, the moving mechanism 4 also includes an electromagnetic locking pin. Multiple limiting slots 12 are provided on the battery housing 1 to accommodate the heads of the electromagnetic locking pins. The electromagnetic locking pins are also wirelessly connected to the control mechanism and can automatically extend or retract upon command from the control mechanism. They cooperate with the limiting slots 12 on the battery housing 1 to lock the position of the moving housing 41, reducing displacement of the moving mechanism 4 due to vibration during vehicle operation and ensuring stable operation of the battery pack under different working conditions. This locking mechanism requires no manual intervention, is fully automated, and enhances the safety and reliability of the battery pack under various driving conditions.

[0031] More specifically, the power module 2 includes multiple interconnected power sub-modules 21, and each of the outermost power sub-modules 21 is provided with a first electrical connection terminal 211 to facilitate connection to the movable housing 41. The multiple power sub-modules 21 are connected in parallel, and this parallel circuit structure enables instantaneous high-current output capability, efficiently meeting the high power demands of the vehicle under rapid acceleration conditions. Furthermore, this parallel structure allows the power module 2 to quickly respond to power demands in dynamic driving scenarios such as vehicle start-up, overtaking, or frequent start-stop operations, providing stable and abundant electrical energy support, significantly improving the vehicle's acceleration performance and power response sensitivity.

[0032] The energy module 3 includes multiple interconnected energy sub-modules 31, with each outermost sub-module 31 equipped with a first electrical connection terminal 211 for connection to the movable housing 41. The multiple energy sub-modules 31 are connected in series, effectively improving the overall output voltage level and perfectly adapting to the high-voltage operating conditions required by the motor during high-speed driving. This series design optimizes the energy transmission path, reduces energy loss during energy conversion, and ensures that the battery pack can continuously output stable and efficient energy during long-distance high-speed driving, thereby significantly extending the vehicle's range and providing users with a smoother and longer-lasting driving experience. This fully demonstrates the adaptive advantages of this structure under varying road conditions.

[0033] Furthermore, the power module 2 is positioned at the end of the battery housing 1 closest to the motor, optimizing the power transmission path. This layout shortens the current transmission distance, reduces line impedance, and improves power transmission efficiency, enabling the battery pack to respond more quickly to the vehicle's power demands in congested urban traffic conditions. This enhances the vehicle's acceleration performance and power response speed, while also facilitating the maintenance and inspection of the power module 2, thus improving the system's maintainability.

[0034] Energy module 3 is positioned at the end of battery housing 1 furthest from the motor, thus placing it at a distance from the motor. Since power module 2 generates significant heat during power supply, this layout effectively reduces the impact of this heat on energy module 3, contributing to optimized overall battery pack thermal management and extending battery life. Simultaneously, this layout facilitates the concentrated arrangement of energy modules 3, improving space utilization and enabling battery housing 1 to achieve higher energy density within a limited space, providing more stable energy support for long-distance driving.

[0035] Based on the adaptive variable module layout automotive battery pack structure proposed in this application, this application also proposes a vehicle that includes the aforementioned adaptive variable module layout automotive battery pack structure. This allows the vehicle to fully utilize the advantages of the adaptive variable module layout, enabling the vehicle to automatically adjust the battery pack's operating mode based on its driving state under different driving conditions, providing better performance and longer range, and significantly improving the user experience.
