Description

Technical Field

[0001] The present invention relates to the field of battery replacement, and in particular to a charging and battery replacement station. Background Art

[0002] With the rapid development of new energy vehicles, charging and swapping stations for replacing or charging batteries in electric vehicles have been widely used. One of the main problems currently faced by charging and swapping stations is temperature control. A large number of battery packs are stored in charging and swapping stations, and the temperature of the battery packs rises during the charging process. However, in order to ensure the best battery performance, including the charging process, the ambient temperature of the charging compartment needs to be adjusted to keep it within a suitable temperature range. Otherwise, the high temperature environment is not conducive to battery charging and is also prone to safety hazards. Therefore, the existing charging and swapping stations all use air conditioning systems to adjust the temperature of the battery pack environment to ensure that the battery pack is in a suitable temperature environment.

[0003] However, in actual charging and swapping stations, since the charging system that charges the battery pack also emits a lot of heat when working, and the charging system and the battery pack are in the same space, its own ventilation system will take away a lot of cold air, affecting the temperature regulation effect of the air-conditioning system. As a result, the temperature inside the charging and swapping station is relatively high, affecting the charging and storage of the battery pack, and even causing safety hazards. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a charging and swapping station to overcome the defect in the prior art that the charging system in the charging and swapping station affects the operation of the air-conditioning system, resulting in high internal temperature of the charging and swapping station, which is not conducive to temperature control of the battery pack.

[0022] Preferably, a waist-shaped connecting hole is provided on the connecting edge, and the waist-shaped connecting hole is used to be adjustably aligned with and connected to the mounting hole on the cabinet panel.

[0045] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0046] like Figure 1-Figure 4 As shown, this embodiment discloses a charging and swapping station, which includes a battery storage space 100, a charging system 200, a sealing device 300, a box 400, a ventilation system 500 and an air conditioning system 600. Among them, a battery rack and a battery transfer device 120 are arranged in the battery storage system 100. The charging system 200 is used to charge the batteries in the adjacent battery compartments, and the ventilation system 500 is used to dissipate heat from the charging system 200. The air conditioning system 600 is used to adjust and control the temperature in the battery storage space 100.

[0047] Among them, Figure 1 As shown, in this embodiment, the sealing device 300 is used to seal the air inlet area A of the ventilation system 500 to form an independent area isolated from the battery storage space 100 where the battery compartment is located. Thus, the battery compartment and the air inlet area A of the ventilation system 500 are isolated by the sealing device 300 to form an independent space, thereby ensuring that the air intake of the ventilation system 500 is independently supplied from the outside, and will not take away the cold air in the space where the battery storage space 100 is located, avoiding affecting the ambient temperature control in the battery storage space 100, ensuring the ambient temperature control effect, and ensuring that the battery pack is within a suitable temperature.

[0048] like Figure 1-Figure 4 As shown, in a preferred embodiment, a battery rack having multiple battery positions in a vertical direction is provided in the charging and swapping station, the charging system includes a charging rack arranged adjacent to the battery rack, and multiple storage positions are vertically arranged on the charging rack, and the charging system also includes multiple charging modules 250 arranged in the storage positions, and the storage positions are arranged one by one with the charging modules 250, and each charging module 250 has an air duct inside, the air inlet 220 of the air duct is connected to the air inlet area A, and the air outlet 240 of the air duct is connected to the air outlet area 510 of the ventilation system 500, so that the fan 510 arranged at the output end of the air outlet area 510 is used to exhaust and dissipate heat. Thus, the external air is obtained from the air inlet area A through the air duct to dissipate and cool the charging module 250, and the hot air after heat exchange is sent from the air outlet 240 to the air outlet area 510 for discharge. In this way, the heat dissipation and cooling effect of the charging module 250 is ensured, so that the charging module 250 can be stably cooled, and the ambient temperature control effect of the battery position will not be affected. In other embodiments, the heat of the charging module 250 may also be discharged in other ways, such as directly connecting the pipes of the fan to each charging module, or other common heat dissipation methods.

[0049] like Figure 1 and Figure 4 As shown, in a preferred embodiment, the air outlet area 510 is preferably in the form of a pipe. The pipe of the air outlet area 510 extends between the charging system 200 and the fan 510 to discharge the hot air after the heat exchange. In the case where there are multiple charging systems 200, the pipe of the air outlet area 510 can lead to each charging module 250, and discharge the hot air through the fan 510. In other embodiments, the air outlet area 510 can also be other known forms of conveying air.

[0050] like Figure 1 As shown, in a preferred embodiment, the charging system 200 also includes a cabinet plate 230 in other areas of the side where the air inlet 220 of the sealed air duct is located, and the sealing device 300 is sealed between the cabinet plate 230 in the vertical direction of the charging rack and the box body 400 of the charging and swapping station to form an air inlet area A. The air inlet of the air inlet area A is arranged below the side wall or at a corresponding position at the bottom of the box body 400 of the charging and swapping station. The charging rack is partially enclosed by the cabinet plate 230 to prevent unnecessary damage caused by the exposure of the charging module 250, etc. At the same time, the cabinet plate 230 of the charging system 200 and the sealing device 300 can be directly used to form an independent air inlet area A.

[0051] like Figure 1 and Figure 2 As shown, in a further preferred embodiment of the air inlet of the air inlet area A, a side panel 420 is provided, and the air inlet of the air inlet area A is provided on the side panel 420. The air inlet on the side panel 420 can adopt a barrier member such as a mesh that can be ventilated or has a filtering function, thereby preventing people from entering the air inlet area A while allowing fresh air to enter the air inlet area A. Of course, in other embodiments, the air inlet can be set at other suitable positions so that the air inlet area A is connected to the external atmospheric environment.

[0052] like Figure 1 As shown, in a further preferred embodiment, the battery rack and the charging rack respectively include two rows of battery racks 110 and two rows of charging racks 210 arranged opposite to each other, and cabinet plates 230 are respectively connected to the opposite side surfaces of the two rows of charging racks 210.

The sealing device 300 seals and connects the cabinet plates 230 of the two rows of charging racks 210 to isolate the air inlet area A. The cabinet plates 230 arranged opposite to each other in the two rows of charging racks 210 and the sealing device 300 arranged between the two cabinet plates 230 are used to seal the air inlet area A of the charging system 200 on both sides, further simplifying the structure of the sealing device, so that the effect of air inlet isolation can be achieved with a more compact structure. The charging rack 210 is preferably a closed structure to form an air duct inside to carry away heat.

[0053] like Figure 5-Figure 7 As shown, in a preferred embodiment, the sealing device 300 includes a first sealing portion 310 and a second sealing portion 320. The first sealing portion 310 is connected between the corresponding two cabinet plates 230 to separate the charging system 200 from the battery rack 110. The second sealing portion 320 is vertically connected to the top of the first sealing portion 310 and extends to the top of the side wall of the box 400 of the charging and swapping station. The air inlet area A is formed between the cabinet plates 230 of the two rows of charging racks 210, the side wall of the box 400 (the side wall of the box 400 in this embodiment is preferably the side plate 420 of the box 400), the first sealing portion 310 and the second sealing portion 320. The first sealing portion 310 and the second sealing portion 320 isolate and seal the air inlet area A in the height direction and the horizontal direction, respectively, to ensure that the air inlet area A can be sealed in both the height direction and the horizontal direction.

[0054] like Figure 7 As shown, in a preferred embodiment, the first sealing portion 310 and the second sealing portion 320 are formed with a bent connecting edge 340 on their sides, and the connecting edge 340 is used to be fixedly connected to the surface of the cabinet board 230. The connecting edge 340 is conducive to fitting other structures for connection. In other embodiments, the first sealing portion 310 and the second sealing portion 320 can also be connected to the cabinet board 230 using different connection methods, such as known methods such as clamping and welding.

The waist-shaped connecting hole 350 is easy to adjust, and when the sealing device 300 and the internal equipment of the charging and swapping station are not accurate enough, resulting in a front-to-back error between the connecting edge 340 and the predetermined position, it can still be aligned and connected with the mounting hole.

[0056] like Figure 7 As shown, in another further preferred embodiment of the connecting edge 340, an inwardly recessed groove 360 ​​is provided on the connecting edge 340, and the groove 360 ​​corresponds to the position of the operating area or display area on the cabinet board 230 to avoid the operating area or display area. The groove 360 ​​can accommodate the operating area or display area to ensure the accurate connection between the first sealing portion 310 or the second sealing portion 320 and the cabinet board.

[0057] like Figure 8As shown, in a preferred embodiment, the sealing device 300 also includes a third sealing portion 330, which is used to seal the bottom space of the charging frame 210 and the reserved space between the charging frame 210 and the side wall of the charging and swapping station. The third sealing portion 330 is used to seal other exposed spaces after the first sealing portion 310 and the second sealing portion 320 are sealed, specifically, the bottom space of the charging frame 210 and the interval space between the charging frame 210 and the side wall of the charging and swapping station are sealed to ensure the tightness of the air intake area, thereby improving the heat exchange efficiency of the ventilation system. Among them, the bottom space of the charging frame 210, in some embodiments, is the space below the cabinet panel 230, which is sealed by the bottom structure of the third sealing portion 330, such as the transverse portion 332. As shown Figure 1 and Figure 2 As shown, the space between the charging frame 210 and the side wall of the charging and swapping station, that is, the space between the frame 410 of the box and the charging frame 210 in some embodiments, is sealed by the longitudinal structure of the third sealing portion 330, such as the longitudinal portion 331. In other embodiments, the third sealing portion 330 can also be various suitable shapes corresponding to the parts that need to be sealed.

[0058] like Figure 8 As shown, in a preferred embodiment, the third sealing portion 330 is an L-shaped structure, including a transverse portion 332 and a longitudinal portion 331, the transverse portion 332 is connected and fixed to the first sealing portion 310, and the longitudinal portion 331 is respectively connected and fixed to the second sealing portion 320 and the transverse portion 332. The third sealing portion 330 of the L-shaped structure is connected to the first sealing portion 310 and the second sealing portion 320 at the same time, so that the structure of the entire air inlet sealing device 300 is more solid and not easy to deform.

[0059] like Figure 1 , Figure 5 and Figure 8 As shown, in a preferred embodiment, a battery transport device 120 for transporting batteries between battery positions is provided between two rows of battery racks 110, and some functional components of the battery transport device 120 are located between two rows of charging racks 210. The first sealing portion 310 has a first concave area 311 that is concave inwardly and a second concave area 312 that is further concave inwardly from the first concave area 311. The first concave area 311 is matched with the longitudinal beam of the battery transport device 120, and the second concave area 312 is matched with the driving unit provided on the longitudinal beam. By avoiding the first concave area 311 and the second concave area 312 from the relevant components of the battery transport device 120, the space of the air inlet area A is increased as much as possible, and the space is fully utilized, thereby ensuring the air volume required for heat exchange and ensuring the heat exchange efficiency. In other embodiments, the first sealing portion 310 can also be formed into a desired shape according to actual needs.

[0060] like Figure 8 As shown, in a further preferred embodiment, the first concave area 311 is formed by splicing two plates in the height direction and the width direction, and the wall panel of the second concave area 312 can be removably fixed to the longitudinal beam. The first concave area 311 is designed as a structure formed by splicing multiple plates. When the battery transport equipment needs to be repaired, only the corresponding plates need to be disassembled, which is convenient for maintenance. Therefore, when performing maintenance, for example, the second concave area 312 can be disassembled separately to repair the drive unit of the battery transport equipment 120, thereby improving work efficiency. When other maintenance is required, the plates of the first concave area 311 at the corresponding position can be disassembled for maintenance or replacement.

The bolt 360 is threadedly connected to the nut 370, and the front end of the bolt 360 is against the front baffle 321. During adjustment, by rotating the bolt 360, it can move relative to the nut 370 and the rear baffle 381, thereby against the front baffle 321 to move relative to the rear baffle 381. In other embodiments, the adjusting member may also be other known adjustment structures.
