Description

Technical Field

[0001] The utility model relates to the technical field of battery swapping, in particular to a power battery charging bracket and a battery swapping station. Background Art

[0002] At present, with the rapid development of the new energy heavy truck industry, the battery swapping station for heavy trucks, as a key infrastructure, its technical solutions and optimizations have become an important direction for the industry's development. In the prior art, the battery swapping station for heavy trucks usually adopts a design in which multiple power batteries are arranged side by side on a bottom tray, and the transfer bin is set on the outermost side or a separately vacated bin in the battery swapping station. However, this design has some drawbacks. Since the battery packs in the battery swapping station are arranged side by side and the gap between any two battery packs is very small, in a high-temperature environment, the air outlet of the water-cooling unit of the front battery pack is directly opposite to the air inlet of the water-cooling unit of the rear battery pack, resulting in too high an air inlet temperature of the water-cooling unit of the rear battery pack, posing an over-temperature risk and affecting the temperature control and overall performance of the battery pack. Summary of the Utility Model

[0003] In view of the above-mentioned drawbacks of the prior art, the utility model provides a power battery charging bracket and a battery swapping station, which are used to solve the problems in the prior art that the concentrated placement of battery packs leads to an over-temperature risk during charging in a high-temperature environment, affecting the temperature control and overall performance of the battery packs, etc.

[0004] To achieve the above and other related purposes, the first aspect of the utility model provides a power battery charging bracket, including: a battery bracket body, wherein: a transfer bin is provided on the battery bracket body, and a plurality of charging bins are arranged on both sides opposite to the transfer bin; for the plurality of charging bins on each side of the transfer bin, a partition and flow guiding assembly is provided between adjacent charging bins; each charging bin includes a containing space for accommodating a power battery; the power battery is provided with a high-temperature exhaust port; the partition and flow guiding assembly is located on the flow path of the high-temperature air flow discharged from the high-temperature exhaust port.

[0005] By relocating the transfer bin originally located on the side to the middle position of the battery bracket body, the multiple charging bins on both sides of the transfer bin are evenly distributed, that is, the charging bins on both sides opposite to the transfer bin are the same, which helps to evenly distribute heat, avoid excessive heat concentration in the central area, and thus reduce the risk of overheating of the power battery in the middle position due to local thermal fields. By installing a partition and flow guiding assembly between each adjacent charging bin respectively, the possibility that the hot air discharged from the water-cooling unit of the front power battery directly enters the air inlet of the water-cooling unit of the rear power battery can be reduced, thereby reducing the influence of the high-temperature exhaust of the water-cooling unit of the front power battery on the air inlet temperature of the water-cooling unit of the rear power battery, and reducing the over-temperature risk of the water-cooling unit of the rear power battery.

[0006] In some embodiments of the first aspect of the present utility model, the intervals between adjacent charging compartments are consistent. During charging, heat will be evenly distributed, alleviating the phenomenon of heat accumulation in the middle.

[0007] In some embodiments of the first aspect of the present utility model, the partition and diversion assembly is an inclined baffle. An inclined baffle is installed between adjacent power batteries. The high-temperature exhaust gas from the water-cooling unit of the front-row power batteries flows and diffuses obliquely upward along the direction of the baffle, greatly reducing the influence on the inlet air temperature of the water-cooling unit of the rear-row power batteries.

[0008] In some embodiments of the first aspect of the present utility model, a diversion inclined surface is provided on the inclined baffle. The diversion inclined surface is designed to be inclined, which can guide the high-temperature exhaust gas to disperse upward, thereby reducing the thermal interference to adjacent power batteries.

[0009] In some embodiments of the first aspect of the present utility model, a fixing member is provided at the bottom of the inclined baffle. The fixing member ensures that the inclined baffle can be stably installed at the required position.

[0010] In some embodiments of the first aspect of the present utility model, a number of fixing screws are provided on the fixing member. By using fixing screws, the installation and disassembly of the inclined baffle become convenient, facilitating maintenance and replacement. The threaded structure allows adjustment of the position of the inclined baffle to adapt to different installation requirements or space limitations.

[0011] In some embodiments of the first aspect of the present utility model, the inclined baffle is made of a high-temperature resistant material. The use of the high-temperature resistant material not only helps to protect the inclined baffle itself from damage, but also helps to protect adjacent power batteries from the influence of high-temperature exhaust gas.

[0012] In some embodiments of the first aspect of the present utility model, a battery fixing structure is provided on the battery support body at the transfer compartment and the charging compartment; the power battery is fixed to the corresponding transfer compartment or charging compartment through the battery fixing structure. The function of the battery fixing structure on the charging compartment is to ensure that the battery is stably fixed in position during charging, avoiding charging failure or other safety hazards caused by movement. Through the battery fixing structure on the transfer compartment, the displacement or fall of the battery during temporary placement can be effectively prevented, ensuring the safety of the power battery.

[0013] In some embodiments of the first aspect of the present utility model, a charging connector adapted to the power battery is further provided on the charging compartment of the battery support body; when the power battery is fixed to the battery support body through the battery fixing structure, the charging connector is connected to the power battery and charging starts. The charging connector can not only ensure the smooth progress of the charging process, but also improve the safety and efficiency of charging.

[0014] To achieve the above and other related objectives, a second aspect of the present utility model provides a battery swapping station, including the power battery charging bracket as described above. When charging the power battery in the battery swapping station under high-temperature environment, by changing the position of the transfer bin and adding a partition flow guiding component between adjacent power batteries, the inlet air temperature of the power battery water-cooling unit can be significantly reduced. At the same time, this retrofit design is not only simple but also has a relatively low cost.

[0015] As described above, a power battery charging bracket and a battery swapping station according to the present utility model have the following beneficial effects: By adding a partition flow guiding component between adjacent batteries, the influence of the high-temperature exhaust gas from the front-row battery outlet on the rear-row batteries can be effectively reduced during charging under high-temperature conditions, thereby reducing the inlet air temperature of the power battery water-cooling unit, improving the charging efficiency and safety; after changing the transfer bin to the middle position of all batteries, the temperature of the batteries can be more evenly distributed, avoiding heat accumulation in the middle position and reducing the adverse effects on battery performance. This retrofit design is simple, only requiring adding a partition flow guiding component in the existing battery gaps and adjusting the transfer bin, without large-scale renovation or adding expensive equipment, resulting in a relatively low retrofit cost.

[0033] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the technical solutions in the embodiments of the present utility model will be further described in detail through the following embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the utility model.

[0034] As Figure 1 shown, it is a schematic structural diagram of a power battery charging bracket in an embodiment of the present utility model. The structure of the power battery charging bracket mainly includes a battery bracket body 1, wherein:

[0035] A transfer bin 2 is provided on the battery bracket body 1, and a plurality of charging bins 3 are arranged on both opposite sides of the transfer bin 2;

[0036] For the plurality of charging bins 3 on each side of the transfer bin 2, a partition flow guiding assembly 31 is provided between adjacent charging bins 3; each charging bin 3 includes a receiving space for accommodating a power battery 32; the power battery 32 is provided with a high-temperature exhaust port; the partition flow guiding assembly 31 is located on the flow path of the high-temperature air flow discharged from the high-temperature exhaust port.

[0037] It should be noted that as Figure 2As shown, in a typical design of a power battery charging bracket, the side compartments of the battery bracket body 1 are usually transfer compartments 2, located on the leftmost or rightmost side of the bracket. In this layout, all the charging compartments 3 face the same direction, and the power batteries 32 are placed side by side and closely adjacent to each other on the charging compartments 3. This arrangement leads to a problem: the air outlet of the water-cooling unit of the power battery in the front row of charging compartments directly faces the air inlet of the water-cooling unit of the power battery in the rear row of charging compartments. When charging under high-temperature conditions, although the water-cooling system will start to reduce the battery temperature, due to the compact space between the charging compartments and the dense arrangement of the power batteries, the hot exhaust gas of the front-row power batteries may significantly increase the temperature of the air inlet of the rear-row power batteries.

[0038] Furthermore, this mutual influence of hot exhaust gas will cause the power batteries in the rear charging compartments to overheat due to the increase in the inlet air temperature. This not only increases the burden on the thermal management system but also may affect the performance and lifespan of the batteries. At the same time, the local thermal field formed by the over-concentration of the batteries may exacerbate the heat accumulation of the middle several batteries, resulting in an abnormal increase in their inlet air temperature, thereby increasing the risk of thermal runaway.

[0039] In some examples, the intervals between adjacent charging compartments 3 are the same. During charging, heat will be evenly distributed, alleviating the phenomenon of heat accumulation in the middle.

[0040] Combined with Figure 1 explanation, the present utility model relocates the transfer compartment 2 originally located on the side, as shown in Figure 2 , to the middle position of the battery bracket body 1, as shown in Figure 1 . The charging compartments 3 are distributed on both sides of the transfer compartment 2 at the same interval, and the number of charging compartments 3 on both sides of the transfer compartment 2 is kept as consistent as possible. This design can avoid the problem that heat accumulates in the middle position when all the batteries are charging with large currents simultaneously under high-temperature conditions, resulting in an overall excessive temperature and an excessive inlet air temperature for the rear several batteries. That is, after the transfer compartment is changed to the middle position of all the batteries, the centralized heat dissipation of the batteries can be effectively improved, and the inlet air temperature can be reduced, thereby avoiding affecting the battery performance or safety due to excessive temperature.

[0041] For example, when the number of charging compartments 3 is even (six), that is, the transfer compartment 2 is located at the center of the arrangement of the power batteries 32, and three power batteries 32 are evenly distributed on each of the left and right sides. This layout adjustment helps to evenly distribute heat, avoid excessive heat concentration in the central area, and thus reduce the risk of overheating of the power batteries in the middle position due to the local thermal field.

[0042] In the embodiment of the present utility model, when the number of charging compartments 3 is odd, the transfer compartment 2 is still located as shown in Figure 1At the middle position of the battery support body 1 shown. For example, when there are seven charging compartments 3, three charging compartments can be set on the left side of the transfer compartment 2, and four charging compartments on the right side; or, four charging compartments can be set on the left side of the transfer compartment, and three charging compartments on the right side. This flexible layout strategy ensures a symmetrical or nearly symmetrical distribution of the charging compartments on both sides of the transfer compartment, thereby helping to evenly distribute the heat generated during charging and reducing the risk of local overheating.

[0043] Furthermore, in the present utility model, partition flow guiding components 31 are respectively installed between adjacent charging compartments 3, that is, two adjacent power batteries on the charging compartment are separated by the partition flow guiding component 31. The partition flow guiding component (31) is located on the flow path of the high-temperature gas flow discharged from the high-temperature exhaust port, and can change the orientation of the high-temperature gas flow discharged from the high-temperature exhaust port, thereby reducing the possibility that the hot air discharged from the water-cooling unit of the front-row power battery directly enters the air inlet of the water-cooling unit of the rear-row power battery.

[0044] In some embodiments, as Figure 3 shown, the partition flow guiding component 31 is an inclined partition.

[0045] It should be noted that, as Figure 4 shown, no inclined partition is installed between adjacent power batteries. The high-temperature exhaust of the water-cooling unit of the front-row power battery is directly facing the air inlet of the water-cooling unit of the rear-row power battery. When charging at a high temperature, the high-temperature exhaust of the front row is directly discharged into the rear row, which is extremely likely to cause the inlet air temperature of the water-cooling unit of the rear-row power battery to be too high. As Figure 5 shown, when an inclined partition is installed between adjacent power batteries, the high-temperature exhaust of the water-cooling unit of the front-row power battery flows and diffuses obliquely upward along the direction of the partition, greatly reducing the influence on the inlet air temperature of the water-cooling unit of the rear-row power battery.

[0046] In some embodiments, as Figure 3 shown, a flow guiding inclined surface 311 is provided on the inclined partition. The flow guiding inclined surface 311 is a slope with a small angle of inclination, that is, the flow guiding inclined surface is designed to be inclined. The flow guiding inclined surface is facing the flow path of the high-temperature gas flow of the high-temperature exhaust port of the front-row power battery, and the inclination direction of the inclined surface is the flow direction of the high-temperature gas flow. As Figure 5 shown, the side structure of the flow guiding inclined surface is wider at the bottom and narrower at the top, thus forming an inclined structure inclined along the flow direction of the high-temperature gas flow. This inclined structure can guide the high-temperature exhaust to disperse upward, thereby reducing the thermal interference to adjacent power batteries.

[0047] In some embodiments, as Figure 3As shown, a fixing member 312 is provided at the bottom of the inclined partition. The fixing member 312 ensures that the inclined partition can be stably installed at the required position. In the present utility model, the fixing member can be set as different connecting members, such as bolts, screws, nuts, rivets, etc., to adapt to different installation environments and requirements.

[0048] In some embodiments, as Figure 3 shown, a number of fixing screws are provided on the fixing member 312. In the present utility model, the fixing member is preferably of a threaded structure, and a number of fixing screws are provided on the fixing member. The inclined partition is fixedly connected to the battery support body 1 through the fixing screws. The use of fixing screws makes the installation and disassembly of the inclined partition convenient, facilitating maintenance and replacement. The threaded structure allows adjustment of the position of the inclined partition to adapt to different installation requirements or space limitations.

[0049] In some embodiments, the inclined partition is made of a high-temperature resistant material. The use of a high-temperature resistant material can ensure that the inclined partition maintains its structural integrity and functional efficiency when facing the high temperature that may be generated during the charging process. The selection of a high-temperature resistant material not only helps to protect the inclined partition itself from damage, but also helps to protect the adjacent power batteries from the influence of high-temperature exhaust. In addition, the use of a high-temperature resistant material also helps to improve the safety of the battery swapping station, ensuring the reliability and durability of the battery swapping station. The high-temperature resistant materials in the embodiments of the present utility model include, but are not limited to: polytetrafluoroethylene, polyether ether ketone, polyphenylene sulfide, polyimide, polysulfone, polyarylate, polytrifluorochloroethylene, polyvinylidene fluoride, polyperfluoroethylene propylene, etc.

[0050] In some embodiments, battery fixing structures are provided on the battery support body 1 at the transfer bin 2 and the charging bin 3; the power battery is fixed to the corresponding transfer bin 2 or charging bin 3 through the battery fixing structure.

[0051] It should be noted that the power battery charging support of the present utility model is mainly used for charging the power battery to facilitate battery replacement for vehicles such as cars or trucks. The charging bin on the power battery charging support is used to place the power battery to be charged for charging. Therefore, a battery fixing structure needs to be provided. The function of the battery fixing structure is to ensure that the battery is stably fixed in position during the charging process, avoiding charging failure or other safety hazards caused by movement.

[0052] The power battery charging bracket also has a transfer bin, and the function of the transfer bin is to temporarily place the power battery to be charged or the fully charged power battery. Setting up the transfer bin facilitates placing the fully charged power battery on the transfer bin in advance, and then the fully charged power battery can be quickly loaded into a car or a truck from the transfer bin, or the power battery to be charged can be temporarily placed on the transfer bin. When there is a vacant position on the charging bin, the power battery to be charged can be transferred from the transfer bin to the charging bin in time, realizing a fast charging and battery swapping process, so as to effectively reduce the waiting time for battery replacement.

[0053] Furthermore, a fixing structure also needs to be set on the transfer bin, which can ensure the safety and stability of the battery on the transfer bin. At the same time, the design of the fixing structure needs to consider the convenience of operation and the rapid battery replacement requirements. Through the battery fixing structure, the battery can be effectively prevented from shifting or falling during temporary placement, ensuring the safety of the power battery.

[0054] In some embodiments, a charging connector adapted to the power battery 32 is also provided on the charging bin 3 of the battery bracket body 1; when the power battery is fixed to the battery bracket body 1 through the battery fixing structure, the charging connector is connected to the power battery and starts charging. The charging connector is designed according to actual needs to be able to adapt to different models and specifications of power batteries, ensuring a firm and safe electrical connection during the charging process. At the same time, the design of the charging connector needs to include a locking mechanism to prevent the charging connector from falling off due to vehicle movement or other external factors during the charging process. The charging connector can not only ensure the smooth progress of the charging process, but also improve the charging safety and efficiency.

[0055] The present utility model also provides a battery swapping station, including the power battery charging bracket as described above. When the power battery in the battery swapping station is charged in a high-temperature environment, by changing the position of the transfer bin and adding a partition and flow guiding component between adjacent power batteries, the inlet air temperature of the power battery water cooling unit can be significantly reduced. At the same time, this retrofit design is not only simple but also has a low cost.

[0056] It should be emphasized that the present utility model reduces the influence of the high-temperature exhaust gas from the front-row battery outlet on the rear-row battery by adding a partition and flow guiding component between adjacent batteries and changing the transfer bin in the battery swapping station to the middle position of multiple batteries, thereby reducing the over-temperature risk, optimizing the temperature control of the battery pack, and improving the operation efficiency and safety of the battery swapping station. The present utility model not only improves the heat dissipation efficiency in the battery swapping station, but also helps to maintain the temperature balance of the battery during the charging process, further enhancing the overall performance and safety of the charging system.

[0057] In summary, the power battery charging bracket and the battery swapping station provided by the present utility model can effectively reduce the influence of the high-temperature exhaust gas from the front-row battery air outlet on the rear-row battery during charging under high-temperature conditions by installing a partition and flow guiding component between adjacent batteries, thereby reducing the inlet air temperature of the power battery water cooling unit, improving the charging efficiency and safety; after changing the transfer bin to the middle position of all batteries, the temperature of the batteries can be more evenly distributed, avoiding heat accumulation in the middle position and reducing the adverse impact on the battery performance. This transformation design is simple, only requiring the addition of a partition and flow guiding component in the existing battery gap and the adjustment of the transfer bin, without large-scale transformation or the addition of expensive equipment, resulting in a relatively low transformation cost. Therefore, the present utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0058] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
