Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a battery replacement box and a vehicle. Background Art

[0002] Heavy-duty truck power battery systems must continuously output high power under complex operating conditions. Their battery compartments typically utilize a multi-layer modular design, integrating numerous high-capacity cells to meet the vehicle's rigid energy reserve requirements. However, due to the vehicle's overall layout and load-bearing structure, the physical space within the battery compartment is strictly constrained, forcing the cells to be arranged in a highly compact manner, significantly compressing the buffer space between modules. This space-intensive design, while increasing system energy density, also significantly alters the thermal characteristics of the battery system.

[0003] Heavy-duty trucks operate under high-load conditions, such as frequent high-current charging and discharging and continuous hill climbing, which generate significant heat in the power battery during operation. To meet long-range requirements, battery systems often utilize densely integrated cells with extremely high energy density. While this design effectively increases energy storage capacity, it also results in a compact internal battery pack layout. Due to the significant increase in the number of cells and their high density, the cumulative effect of heat accumulation between battery cells during continuous high-power charging and discharging is significantly enhanced. However, due to the physical size constraints of containerized battery boxes, efficient heat removal from the box is difficult. Summary of the Invention

[0032] In this embodiment, the heavy truck power battery system needs to cope with the continuous high power output demand under complex working conditions, and the battery swap box adopts a multi-layer modular architecture to integrate high-capacity battery cells to meet the energy reserve requirements. However, due to the limitations of the vehicle layout and load-bearing structure, the physical space height of the battery box is limited, forcing the battery cells to be densely arranged and compressing the buffer area between modules. Although this intensive design improves the energy density, it makes thermal management more difficult. Therefore, in order to solve the above problems, the present invention provides a battery swap box and vehicle, such as Figure 1 As shown, the battery replacement box can include battery components 02 and temperature control components 01.

[0033] The battery assembly 02 can store electrical energy, drive the electric motor to provide power, and supply power to on-board equipment.

[0034] The temperature control assembly 01 may include a frame unit 12 and two temperature control units 11. The frame unit 12 may be made of a strip profile and may be connected to the battery assembly 02. The temperature control unit 11 may be connected to the hollow cavity of the frame unit 12. When the vehicle is traveling on bumpy or rough roads, the frame unit 12 may absorb shock and vibration through high-strength materials to prevent damage to the internal structure of the battery. One side of the frame unit 12 in the longitudinal direction is the first side, which may be as follows: Figure 2 The left side shown in FIG. 1 and the other side of the frame unit 12 in the length direction is the second side, which can be as shown in FIG. Figure 2 The right side is shown. One temperature control unit 11 can be set on the first side, and the other temperature control unit 11 can be set on the second side. In this way, two temperature control units 11 are set in the hollow cavity of the frame unit 12, thereby increasing the temperature control effect on the battery unit. The temperature control unit 11 can be connected to the battery assembly 02. The space between the temperature control unit 11 and the space enclosed by the frame unit 12 away from the side of the battery assembly 02 is the hoisting space, and part of the frame unit 12 on both sides of the width direction of the frame unit 12 passes through the hoisting space. In this way, when hoisting the battery swap box, the battery swap box can be replaced by hooking the hook from the inside to the outside of the hoisting space, so that the length and width of the battery swap station can be more compact, thereby effectively realizing the width optimization control when hoisting the battery swap box.

[0035] In this embodiment, if Figure 2 、 Figure 3 As shown, the two temperature control units 11 can be spaced apart along the length direction of the frame unit 12. The spacing can make the length distance between two adjacent hoisting spaces longer, and four hooks can be used during hoisting, so that the distance between each hook is as large as possible, thereby improving the stability when hoisting the battery box.

[0036] In this embodiment, if Figure 4 、 Figure 5As shown, the temperature control unit 11 may include a heat dissipation module 111 and a temperature control module 112. The heat dissipation module 111 and the temperature control module 112 may be connected to the frame unit 12, respectively. The heat dissipation module 111 and the temperature control module 112 may be connected to the battery assembly 02, respectively. The heat dissipation module 111 on the first side, the temperature control module 112 on the first side, the temperature control module 112 on the second side, and the heat dissipation module 111 on the second side are arranged in sequence along the length direction of the frame unit 12. The minimum distance between the heat dissipation module 111 and the space enclosed by the frame unit 12 away from the battery assembly 02 may be a first distance. The minimum distance between the temperature control module 112 and the space enclosed by the frame unit 12 away from the battery assembly 02 may be a second distance. The first distance may be smaller than the second distance. The space between the top of the temperature control module 112 and the space enclosed by the frame unit 12 away from the battery assembly 02 is the hoisting space. This not only achieves efficient heat dissipation of the battery swap box, but also enables the battery swap box to be hoisted and replaced, while the battery swap box meets the characteristics of high battery life and small size. When the battery box is hoisted, if the hoist shakes, it may collide with the frame unit 12. After the frame unit 12 is damaged, the height of the heat dissipation module 111 is relatively high. Figure 3 In the up and down directions shown, the heat dissipation module 111 can withstand part of the impact force. Since the price of the heat dissipation module 111 is lower than that of the temperature control module 112 and it is easier to replace, damage to the temperature control module 112 of the temperature control component 01 can be avoided as much as possible.

[0037] In other embodiments, Figure 5 As shown, the heat dissipation module 111 may include a radiator 1111 and a fan 1112. The radiator 1111 and the fan 1112 may be connected to the frame unit 12, respectively. The radiator 1111 may be in communication with the battery assembly 02. The fan 1112 may be provided at both ends of the frame unit 12 along the length direction. After the liquid is heated by heat exchange with the battery, the liquid exchanges heat with the radiator 1111. The radiator 1111 can quickly absorb the heat generated by the battery assembly 02. The fan 1112 then cools the radiator 1111, thereby achieving heat conduction from the space enclosed by the radiator 1111, the fan 1112, and the frame unit 12 to the external space.

[0038] The minimum distance between the fan 1112 and the space enclosed by the frame unit 12 away from the battery assembly 02 is the first distance. The space between the top of the radiator 1111 and the top of the fan 1112 and the space enclosed by the frame unit 12 away from the battery assembly 02 is the hoisting space, which can meet the heat dissipation requirements of the battery swap box. At the same time, when the battery swap box is hoisted, if the hoist shakes, it may collide with the frame unit 12. Then, due to the high height of the radiator 1111 and the fan 1112, the height can be as follows: Figure 3In the up and down directions shown, the radiator 1111 and the fan 1112 can withstand part of the impact force. Since the price of the radiator 1111 and the fan 1112 is lower than that of other components and they are easier to replace, damage to the temperature control module 112 can be avoided as much as possible.

[0039] In this embodiment, if Figure 1 、 Figure 5 As shown, the frame unit 12 may include a first frame 121, a first protective plate 122, an air inlet 123, and an air guide 124. The first frame 121 may be made of a strip profile, the first frame 121 may be connected to the battery assembly 02, and the first protective plate 122, the air inlet 123, and the air guide 124 may be connected to the first frame 121, respectively. The first frame 121 may be installed with the temperature control unit 11 and the battery replacement battery box may be hoisted. The first protective plate 122, the air inlet 123, the air guide 124, and the top surface of the battery assembly 02 may be surrounded to form an installation space. The first protective plate 122 may prevent foreign matter from intruding into the installation space, and avoid short circuits or corrosion of the lines and components in the installation space. The heat dissipation module 111 and the temperature control module 112 may be respectively arranged in the installation space. The heat dissipation module 111 and the temperature control module 112 may be respectively connected to the first frame 121. The installation space can be connected to the outside of the installation space via the air inlet 123 and air guide 124. The air guide 124 can be located on the side of the heat dissipation module 111 away from the temperature control module 112. The air inlet 123 can be located on one side of the first frame 121 in the width direction. This prevents foreign matter from entering while improving the efficiency of cooling air intake. The air guide 124 can be a fan 1112 or a blower, and can include grilles or louvers to filter large dust and debris from the air, protecting the battery assembly 02 from contamination. The air guide 124 can cooperate with the air inlet 123 to exhaust the hot air within the installation space to the outside of the installation space. One side of the first frame 121 in the longitudinal direction can be the third side, and the other side of the longitudinal direction can be the fourth side. One temperature control unit 11 can be located on the third side, and the other temperature control unit 11 can be located on the fourth side. The space between the top of the temperature control module 112 and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 can serve as the hanging space. Portions of the first frame 121 on both sides of the first frame 121 in the width direction can pass through the hoisting space. The first protective plate 122, the air inlet 123, and the air guide 124 can be spaced apart from the hoisting space. This spacing can increase the distance between two adjacent hoisting spaces. When hoisting, four hooks can be used, and the distance between each hook can be as large as possible, thereby improving the stability when hoisting the battery box.

[0040] The battery swap box may include a driving state. The driving state may include the air guide 124 guiding the heat dissipation gas from the heat dissipation module 111 in a direction away from the temperature control module 112 and away from the direction opposite to the driving direction, and the tangent line of the blade length direction in the grid or shutter of the air guide 124 is directed toward the oblique rear of the vehicle, that is, the oblique rear of the vehicle's driving direction to prevent the gas outside the battery swap box from affecting the heat dissipation effect during driving.

[0041] In this embodiment, if Figure 5 As shown, the temperature control module 112 may include a compressor 1122 and a water pump 1121. The compressor 1122 and the water pump 1121 may be connected to the frame unit 12, respectively. The compressor 1122 and the water pump 1121 may be connected to the heat dissipation module 111, respectively. The compressor 1122 converts electrical energy into mechanical energy, using a motor to drive a scroll disk or other mechanical structure within the compressor 1122, thereby compressing the liquid. The battery assembly 02 releases a large amount of heat during the charging and discharging process. Excessive temperature can lead to performance degradation, shortened lifespan, and even thermal runaway. The water pump 1121 circulates liquid to promptly dissipate the heat generated by the battery assembly 02, ensuring that the battery assembly 02 remains within an appropriate operating temperature range. The heat dissipation module 111 on the first side, the compressor 1122 on the first side, the compressor 1122 on the second side, and the heat dissipation module 111 on the second side are arranged sequentially along the length of the frame unit 12. The minimum distance between the compressor 1122 and the space enclosed by the frame unit 12, away from the battery assembly 02, may be the third distance. The minimum distance between the water pump 1121 and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 can be the fourth distance. The first distance can be less than the third distance, and the first distance can be less than the fourth distance. The space between the side of the compressor 1122 and water pump 1121 away from the heat dissipation module 111 and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 is the hoisting space. Because the first distance is less than the third distance, and the first distance is less than the fourth distance, if the hoist shakes during hoisting, it may collide with the frame unit 12. If the frame unit 12 is damaged, the radiator 1111 and fan 1112 can withstand some of the impact force due to their higher height. Because the price of the radiator 1111 and fan 1112 is lower than that of other components and they are easier to replace, damage to the compressor 1122 and water pump 1121, which are more expensive and difficult to replace, can be minimized.

[0042] In this embodiment, if Figure 5As shown, the temperature control module 112 may further include a current exchanger 1123. The current exchanger 1123 may be connected to the frame unit 12. The current exchanger 1123 may be electrically connected to the battery assembly 02. The current exchanger 1123 may convert the high-voltage direct current of the battery assembly 02 into low-voltage direct current to power the vehicle, or the current exchanger 1123 may convert the low-voltage direct current of the battery assembly 02 into high-voltage direct current to provide a stable voltage for the high-voltage system. The current exchanger 1123 may adjust the output voltage to adapt to load changes and ensure the stable operation of the battery replacement box. The current exchanger 1123 may be arranged on the side of the compressor 1122 away from the heat dissipation module 111. The minimum distance between the current exchanger 1123 and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 may be the fifth distance. The first distance may be less than the fifth distance. The space between the top of the current exchanger 1123 and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 may be a hoisting space. Since the first distance is smaller than the fifth distance, when hoisting, if the hoist shakes, it may collide with the frame unit 12. After the frame unit 12 is damaged, the radiator 1111 and the fan 1112 are at a higher height, so the radiator 1111 and the fan 1112 can withstand part of the impact force. Since the price of the radiator 1111 and the fan 1112 is lower than that of other components and they are easier to replace, the current exchanger 1123, which is more expensive and difficult to replace, can be avoided as much as possible from being damaged.

[0043] In this embodiment, if Figure 5As shown, the temperature control module 112 may further include a heater 1124. The heater 1124 may be connected to the frame unit 12. The heater 1124 may be electrically connected to the battery assembly 02. The heater 1124 may be arranged on a side of the compressor 1122 away from the heat dissipation module 111. The current exchanger 1123 may be arranged on one side of the frame unit 12 in the width direction. The heater 1124 may be arranged on the other side of the frame unit 12 in the width direction. The minimum distance between the heater 1124 and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 may be the sixth distance. The first distance may be less than the sixth distance. The space between the heater 1124 and the current exchanger 1123 and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 is the hoisting space. The first distance is smaller than the sixth distance. This allows the hoist to shake during installation and potentially collide with the frame unit 12. If the frame unit 12 is damaged, the radiator 1111 and fan 1112 can withstand some of the impact due to their higher height. Since the radiator 1111 and fan 1112 are relatively inexpensive and easily replaceable compared to other components, damage to the heater 1124, which is expensive and difficult to replace, can be minimized. When the external ambient temperature is low, the performance of the battery assembly 02 degrades. The heater 1124 is a thermistor with a positive temperature coefficient, whose resistance increases with increasing temperature. This characteristic gives the heater 1124 a low resistance at low temperatures, enabling efficient heating. However, when the temperature exceeds a certain threshold, the resistance increases rapidly, limiting current flow and preventing overheating. The compressor 1122 is primarily used in the refrigeration cycle, compressing the liquid to increase its temperature and pressure, thereby achieving a cooling effect. During the heating process, the compressor 1122 does not directly participate in the generation and transfer of heat. Heater 1124 has a simple structure, small size, and light weight, making it easy to install and maintain. Compared to the complex compressor 1122 system, heater 1124 has lower manufacturing and operating costs. Heater 1124 also features a self-limiting temperature feature, automatically reducing power when overheating to prevent damage. This feature ensures high reliability and stability over long-term use.

[0044] In this embodiment, if Figure 5As shown, the temperature control assembly 01 may also include a refill unit 13. The refill unit 13 may be connected to the frame unit 12. The temperature control unit 11 on the first side, the refill unit 13, and the temperature control unit 11 on the second side may be spaced apart in sequence along the length of the frame unit 12. The refill unit 13 may be in communication with the temperature control unit 11. The space between the refill unit 13 and the temperature control unit 11 and the frame unit 12, respectively, and the space away from the battery assembly 02, may serve as a hoisting space. The temperature control unit 11 requires regular refilling of liquid. The temperature control unit 11 is in communication with the refill unit 13. When the temperature control unit 11 is short of liquid, the refill function is triggered, and the refill unit 13 can refill the temperature control unit 11 with liquid. When the temperature of the liquid rises, its volume expands significantly. If no space is reserved, the sudden increase in internal pressure may cause pipeline rupture and seal failure. Therefore, a certain amount of expansion space is provided within the hollow cavity of the refill unit 13 to prevent negative effects such as liquid expansion and pipeline rupture.

[0045] In another embodiment, the temperature control assembly 01 may further include multiple rehydration units 13. The multiple rehydration units 13 may be connected to the frame unit 12. The multiple rehydration units 13 are arranged within the installation space, with some located between two adjacent hoisting spaces, on one side of the installation space in the longitudinal direction, and others located on the other side of the installation space in the longitudinal direction. The temperature control unit 11 on the first side, the multiple rehydration units 13, and the temperature control units 11 on the second side may be sequentially spaced along the length of the frame unit 12. The multiple rehydration units 13 may be connected to the temperature control unit 11. The space between the rehydration units 13 and the temperature control unit 11, respectively, and the side of the space enclosed by the frame unit 12 away from the battery assembly 02 may serve as the hoisting space. The temperature control unit 11 requires regular rehydration of liquid. The temperature control unit 11 is connected to the rehydration units 13. When the temperature control unit 11 is low on liquid, rehydration is triggered, and the rehydration units 13 replenish the temperature control unit 11. Having multiple rehydration units 13 can reduce the number of manual maintenance cycles, thereby reducing costs.

[0046] In this embodiment, if Figure 6 、 Figure 7 As shown, the vehicle may also include a vehicle body 03. The battery assembly 02 is detachably connected to the vehicle body 03 on the side away from the temperature control assembly 01, and the battery assembly 02 is electrically connected to the vehicle body 03. The battery swap box can provide kinetic energy to the vehicle body 03, allowing the vehicle body 03 to operate normally. At the same time, the vehicle body 03 can withstand the dynamic loads generated by passengers, cargo, and driving, avoiding deformation.

[0047] In this embodiment, if Figure 5As shown, the frame unit 12 may include a first frame 121, a first protective plate 122, an air inlet 123, and an air guide 124. The first frame 121 is made of a strip of profile. The first protective plate 122 prevents foreign matter from entering the installation space, preventing short circuits or corrosion of wiring and components within the installation space. The first frame 121 is connected to the battery assembly 02. The first protective plate 122, air inlet 123, and air guide 124 are each connected to the first frame 121. The first frame 121 absorbs bumps and impacts during vehicle travel, reducing mechanical stress on the battery assembly 02. The first protective plate 122, air inlet 123, air guide 124, and the top surface of the battery assembly 02 enclose the installation space. The temperature control unit 11 is disposed within the installation space and is connected to the first frame 121. The installation space is connected to the external space via the air inlet 123 and air guide 124. The air guide 124 is located on both sides of the first frame 121 in the longitudinal direction. The air inlet 123 is located on one side of the first frame 121 in the width direction. This prevents foreign matter from entering. For example, if it is located above the battery swap box, foreign matter will easily enter the installation space. It also improves the efficiency of cooling air entry. The air inlet 123 can be a fan 1112 or a blower, and the air guide 124 has an air intake grille or louvers to filter large particles of dust and debris from the air, protecting the battery assembly 02 from contamination. The air guide 124 can cooperate with the air inlet 123 to discharge the hot air within the installation space to the outside of the installation space. One side of the first frame 121 in the longitudinal direction is the third side, and the other side of the length is the fourth side. One temperature control unit 11 is located on the third side. Another temperature control unit 11 is located on the fourth side. The space between the temperature control assembly 01 and the side of the space enclosed by the first frame 121 away from the battery assembly 02 is the hoisting space. Portions of the first frame 121 on both sides of the first frame 121 in the width direction pass through the hoisting space. The first protective plate 122, the air inlet 123, and the air guide 124 are spaced apart from the hoisting space. This spacing allows for a longer distance between two adjacent hoisting spaces. During hoisting, four hooks can be used, with the distance between each hook as large as possible, thereby improving stability when hoisting the battery box.

[0048] The battery swap box includes a driving state. The driving state includes the air guide 124 guiding the heat dissipation gas discharged from the temperature control unit 11 toward the external space on both sides of the length direction of the first frame 121 and away from the direction opposite to the driving direction of the vehicle body 03. The tangent line of the blade length direction in the grid or shutter of the air guide 124 is directed toward the oblique rear of the vehicle, that is, the oblique rear of the vehicle's driving direction. This can prevent the gas outside the battery swap box from affecting the heat dissipation effect during driving.

[0049] In other embodiments, Figure 4As shown, the battery assembly 02 may include a support unit 21 and multiple battery cells 22. The multiple battery cells 22 provide functions for the vehicle, allowing it to travel normally. The support unit 21 may include a second frame 211 and a second protective plate 212. The second protective plate 212 prevents foreign matter from entering the installation space, preventing short circuits or corrosion of wiring and components within the installation space. The second frame 211 absorbs bumps and impacts during vehicle travel, reducing mechanical stress on the battery assembly 02. The temperature control module 112 of the temperature control assembly 01 may also include a control box 1125. The temperature control module 1125 is connected to the temperature control assembly 01 frame unit 12. The temperature control module 1125 is electrically connected to the temperature control assembly 01 compressor 1122, the temperature control assembly 01 current exchanger 1123, the temperature control assembly 01 heater 1124, the temperature control assembly 01 radiator 1111, and the temperature control assembly 01 battery assembly 02. The control box 1125 of the temperature control assembly 01 is located on the side of the temperature control assembly 01 compressor 1122 away from the radiator 1111 of the temperature control assembly 01. The heater 1124, control box 1125, and current exchanger 1123 of the temperature control assembly 01 are arranged sequentially along the width of the frame unit 12 of the temperature control assembly 01. The minimum distance between the control box 1125 and the battery assembly 02 of the temperature control assembly 01 is the seventh distance. The seventh distance of the temperature control assembly 01 is smaller than the sixth distance of the temperature control assembly 01, the fifth distance of the temperature control assembly 01, the third distance of the temperature control assembly 01, the second distance of the temperature control assembly 01, and the first distance of the temperature control assembly 01. When hoisting in this way, if the hoist shakes, it may collide with the temperature control component 01. Since the radiator 1111 and the fan 1112 are at a high height, the radiator 1111 and the fan 1112 can withstand part of the impact force. Since the price of the radiator 1111 and the fan 1112 is lower than that of other components and it is easier to replace, the heater 1124, which is more expensive and difficult to replace, can be avoided as much as possible.

[0050] In other embodiments, the temperature control component 01 is easy to transport and assemble on site, reducing installation time and costs. The temperature control component 01 has a compact structure and occupies a small area, making it suitable for places with limited space. It supports indoor and outdoor installation and adapts to different environmental requirements. The temperature control component 01 is designed with ease of maintenance in mind, making it easy to clean and inspect daily. It is equipped with an intelligent monitoring system to monitor the operating status in real time, provide early warning of potential problems, and reduce sudden failures. Durable materials and long-life components are used to reduce replacement frequency and maintenance costs. Buffer devices are provided at key parts of the temperature control component 01 to reduce the impact of external impact on core components. Secondary components are designed to withstand impact (such as the heat dissipation module 111) to protect core components from damage. It undergoes anti-collision testing before leaving the factory to ensure that it can withstand certain impacts during transportation or installation. The temperature control component 01 performs well in installation, maintenance, and impact resistance. Its modular design, intelligent monitoring, and sturdy structure enable it to operate stably in a variety of environments.

[0051] In other embodiments, the temperature control component 01 is made into a side-mounted stepped temperature control component 01 through reasonable layout. The controller, compressor 1122, and water pump 1121 can avoid the hoisting space area, reducing the risk of accidental collision during the hoisting of the battery swap box. A large-capacity expansion and rehydration unit 13 is placed in the installation space, and a side-mounted stepped temperature control component 01 is arranged on both sides of the installation space, thereby improving the heat dissipation function of the battery swap box. The cooling capacity is increased from the current maximum 13kW to 20kW for the double-sided temperature control unit. Make full use of the reserved stepped space and increase the heating capacity of the heater 1124 to support a maximum of 32kW. At the same time, the frame unit 12 not only strengthens the top strength of the battery swap box, but also avoids the waste of multiple layers of ordinary cover plates. The design and layout of the side-mounted stepped temperature control component 01 retains the hoisting space of the battery swap station. On the basis of meeting the existing battery swap hoisting requirements, the top space utilization rate is improved. By adjusting the direction of the air guide plates on both sides, it is possible to meet the requirements of the battery swap battery box being used on the vehicle body 03. When the battery swap battery box is in high-speed driving, the heat dissipation and exhaust to both sides are affected by the shear obstruction of the airflow in the driving direction, and the hot air circulation problem is reduced.
