Description

Technical Field

[0001] The present invention relates to the field of vehicle battery replacement technology, and in particular to a battery replacement station with staggered spare battery boxes. Background Art

[0002] In the field of electric vehicle battery swapping, battery swap stations serve as crucial infrastructure for providing rapid battery replacement services for electric vehicles. The layout of the internal battery boxes and the configuration of the chargers have long been a focus of industry attention. Currently, the most common battery layout at battery swap stations utilizes a multi-layer, multi-column arrangement, maximizing the number of battery boxes placed within the limited station space to accommodate the battery swap needs of a wider range of electric vehicles. The chargers are typically located independently of the battery boxes and distributed in different areas of the station. During battery swap operations, the battery boxes often need to be moved and adjusted to ensure smooth installation.

[0003] However, when battery swap stations are limited, the multi-layer, multi-row layout of battery boxes leaves the space between them very narrow. During the swap process, the frequent movement of battery boxes can easily lead to collisions, potentially damaging them and posing a safety threat to the operators. This makes it difficult to ensure both efficient and safe swaps. Furthermore, traditional solutions require removing the upper battery boxes before swapping the lower battery boxes. This additional step increases the time and complexity of swapping, reduces swap efficiency, and fails to meet the rapid swapping needs of electric vehicles. Summary of the Invention

[0016] In some embodiments, the distance between the first charging seat and the vertical side wall of the warehouse body that is close to and parallel to the first horizontal direction is a third distance; the distance between the third charging seat and the vertical side wall of the warehouse body that is close to and parallel to the first horizontal direction is a fourth distance; the second distance is greater than the third distance; the second distance is greater than the fourth distance.

[0017] In some embodiments, the vertical distance between the bottom of the backup battery box on the first charging base and the top of the backup battery box on the second charging base is a fifth distance; and the third distance is greater than the fifth distance.

[0018] In some embodiments, the warehouse body includes a first vertical side wall and a second vertical side wall; the entrance and exit are arranged on the first vertical side wall; the second vertical side wall is perpendicular to the first vertical side wall; the second vertical side wall is close to the charger;

Because of the staggered arrangement, the spare battery boxes on the second storage layer are not adjacent to other spare battery boxes in the horizontal direction. This not only omits the lifting and lowering steps, but also speeds up the horizontal movement and is less likely to collide with other spare battery boxes, providing sufficient safety. Therefore, the spare battery boxes on the second storage layer can be lifted first during battery replacement, which can achieve different priority battery replacement lifting sequences and improve battery replacement efficiency and safety.

Unless otherwise specified, "plurality" means two or more.

[0033] To meet the demand for battery swaps, currently common electric vehicle battery swap stations often feature multi-layer, multi-row battery layouts. This also results in extremely crowded battery boxes when the station space is small. This makes it easy for battery boxes to collide with each other when adjusting their positions before swapping, posing a risk of damage. Furthermore, when swapping batteries in the lower battery boxes, the upper battery boxes must be removed first. This additional step increases the time and complexity of battery swaps, reduces swap efficiency, and fails to meet the rapid battery swap requirements of electric vehicles.

[0034] In this embodiment, a battery swap station is provided in which the backup battery boxes 70 are staggered. Figures 1 to 5 As shown, Figure 4 Used to reflect the positional relationship of multiple backup battery boxes; Figure 5The battery swap station includes a battery swap compartment 10, a charger 20, a first charging station 30, a second charging station 40, a third charging station 50, and a plurality of spare battery boxes 70.

[0035] The battery swap compartment 10 has an entrance 11 on one vertical side, through which the battery box can enter and exit the battery swap compartment 10 during battery swapping. The inner cavity of the battery swap compartment 10 includes a first accommodating layer 12 and a second accommodating layer 13, with the second accommodating layer 13 located above the first accommodating layer 12. The entrance 11 is flush with the height of the second accommodating layer 13, that is, for the battery box in the first accommodating layer 12, it needs to be moved to the height of the second accommodating layer 13 before installation.

[0036] The charger 20 is located in the first accommodation layer 12 , and the charger 20 can supply power to all charging seats in the battery swap compartment 10 .

[0037] The first charging station 30 is located on the second receiving layer 13. The first charging station 30 is located directly above the charger 20, so that the space above the charger 20 can be fully utilized. In another embodiment, a plurality of first charging stations 30 can be arranged along the first horizontal direction.

[0038] The second charging seat 40 is located on the first receiving layer 12. The space of the second receiving layer 13 directly above the second charging seat 40 and the entrance 11 are distributed along the first horizontal direction.

[0039] The third charging station 50 is located on the first storage layer 12. The charger 20, the second charging station 40, and the third charging station 50 are arranged in sequence along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction. In another embodiment, multiple third charging stations 50 can be arranged along the first horizontal direction.

[0040] like Figure 4 As shown, multiple backup battery boxes 70 are distributed on the first charging seat 30 , the second charging seat 40 and the third charging seat 50 , and the bottom of the backup battery box 70 located in the second accommodating layer 13 is higher than the top of the backup battery box 70 located in the first accommodating layer 12 .

[0041] The spare battery box 70 on the first charging seat 30 does not need to be moved vertically during transportation. In the horizontal movement process, there is no obstruction in the second storage layer 13 that needs to be passed through. It only needs to be detached from the charging seat and then moved directly horizontally to the entrance and exit 11 to be transported out of the battery swap warehouse 10, which can greatly improve the battery swap efficiency. In addition, there is only the first charging seat 30 in the second storage layer 13, which is not adjacent to other spare battery boxes 70 in the horizontal direction. When hoisting, not only the lifting step is omitted, but the horizontal movement speed can be accelerated, making it less likely to collide with other spare battery boxes 70 and cause damage.

[0042] The upper spaces of the second charging station 40 and the third charging station 50 are both empty. Compared with the battery swap compartment 10 where each layer is filled with battery boxes, when using the spare battery boxes 70 of the second charging station 40 and the third charging station 50 for battery swapping, there is no need to move the upper battery boxes to make room for hoisting, which further improves the battery swap efficiency. Figure 2 As shown, the battery swap robot 80 is detachably connected to the top of the battery swap warehouse 10, and the battery swap robot 80 can lift and transport the spare battery box 70.

[0043] By staggering the spare battery boxes 70 in the first storage layer 12 and the second storage layer 13, the spare battery boxes 70 will not be obstructed by other spare battery boxes 70 during the hoisting and transportation process, and there is no need to transfer other spare battery boxes 70 on the moving path leading to the entrance and exit 11, thereby greatly improving the battery replacement efficiency. Because of the staggered arrangement, the spare battery boxes 70 in the second storage layer 13 are not adjacent to other spare battery boxes 70, so they will not collide with other spare battery boxes 70 in the horizontal direction, and have sufficient safety. When replacing batteries, the spare battery boxes 70 in the second storage layer 13 can be hoisted first, and different priority battery replacement hoisting sequences can be achieved to improve battery replacement efficiency and safety.

[0044] In this embodiment, if Figure 3 As shown, the horizontal width of the entrance and exit 11 is adjustable. The battery swap warehouse 10 may include a warehouse body 14 and a movable door 15. The entrance and exit 11 is provided on the warehouse body 14, and the movable door 15 and the entrance and exit 11 are located on the same side of the warehouse body 14. The movable door 15 is at the same height as the second accommodating layer 13, and the space of the second accommodating layer 13 directly above the third charging seat 50 and the movable door 15 are arranged along the first horizontal direction. The horizontal width of the entrance and exit 11 is positively correlated with the degree of opening of the movable door 15, that is, the horizontal width of the entrance and exit 11 can be changed by adjusting the opening of the movable door 15. By adjusting the horizontal width of the entrance and exit 11 to be larger, the displacement distance of the battery swap robot 80 in the second horizontal direction can be larger, thereby making the parking tolerance of the battery swap vehicle larger and improving the battery swap efficiency to a certain extent. In addition, when hoisting and transporting the spare battery box 70 in the first storage layer 12, after the spare battery box 70 is moved to the second storage layer 13, the spare battery box 70 can be moved away from the first charging seat 30 to avoid collision with the spare battery box 70 on the first charging seat 30, thereby further improving the safety during the battery replacement process.

[0045] In this embodiment, if Figure 5As shown, the battery swap station with staggered spare battery boxes 70 can also include a transfer seat 60. When the spare battery boxes 70 in the battery swap compartment 10 are fully loaded, the empty battery boxes that have been replaced can be placed on the transfer seat 60. The transfer seat 60 is located in the first accommodating layer 12, so as not to hinder the lifting and transportation of the spare battery boxes 70 on the first charging seat 30. The transfer seat 60 and the second charging seat 40 are arranged along the first horizontal direction. The transfer seat 60 is located on the side of the second charging seat 40 close to the entrance and exit 11, so that after the empty battery box is unloaded, the empty battery box can be placed on the transfer seat 60 as quickly as possible. During idle periods, the battery boxes on the transfer seat 60 can be transferred to other charging seats. In some embodiments, when the battery replacement frequency is low, the empty battery box can be transferred to the first charging seat 30 to ensure that the first charging seat 30 with the fastest battery replacement speed is loaded with spare battery boxes 70, and there is also sufficient time to charge the empty battery box; when the battery replacement frequency is high or the first charging seat 30 is fully loaded, the empty battery box can be transferred to the second charging seat 40 or the third charging seat 50.

[0046] In this embodiment, if Figure 5 As shown, there is one third charging station 50 arranged along the second horizontal direction. The number of third charging stations 50 arranged along the second horizontal direction is the number of columns, that is, the third charging stations 50 are arranged in a row along the first horizontal direction. Compared with setting up multiple columns, this embodiment reduces the space occupied by the battery swap station and improves overall space utilization.

[0047] In this embodiment, if Figure 5 As shown, the spacing between the second charging station 40 and the third charging station 50 along the second horizontal direction is a first spacing; the spacing between the second charging station 40 and the charger 20 along the second horizontal direction is a second spacing. The first spacing is greater than the second spacing, so that the spare battery box 70 on the third charging station 50 is less likely to collide with the spare battery box 70 on the second charging station 40 during hoisting. Furthermore, the side of the third charging station 50 away from the second charging station 40 serves as the charging compartment side wall, reducing the possibility of collision between the spare battery boxes 70, reducing the risk of collision and collision damage, and improving safety during the battery replacement process.

[0048] In this embodiment, if Figure 5As shown, the first charging station 30 is spaced apart from a vertical sidewall of the storage body 14 that is adjacent and parallel to the first horizontal direction by a third spacing, and the third charging station 50 is spaced apart from a vertical sidewall of the storage body 14 that is adjacent and parallel to the first horizontal direction by a fourth spacing. The second spacing is greater than the third spacing, and the second spacing is greater than the fourth spacing. The second spacing is larger, so when the spare battery box 70 on the second charging seat 40 is hoisted to the second accommodating layer 13, it is not easy to collide with the spare battery box 70 on the first charging seat 30; the third spacing and the fourth spacing are smaller, which can ensure that the spare battery boxes 70 on the first charging seat 30 and the third charging seat 50 are not easy to collide with the side wall of the warehouse body 14, while reducing the possibility of collision with other spare battery boxes 70 to a greater extent. Therefore, by dividing the first spacing, the second spacing, the third spacing and the fourth spacing into different levels, and dividing the battery replacement priority levels at different heights, this embodiment as a whole achieves the design requirements of a compact structure of the battery replacement station, not only avoiding the collision of the battery box with the side wall of the warehouse body 14, but more importantly avoiding the collision of adjacent batteries to avoid greater losses, thereby improving the safety and efficiency of the battery replacement process.

[0049] In this embodiment, the vertical distance between the bottom of the spare battery box 70 on the first charging seat 30 and the top of the spare battery box 70 on the second charging seat 40 is the fifth distance. The third distance is greater than the fifth distance. When the spare battery box 70 is hoisted in the air, the spare battery box 70 has a larger swing in the horizontal direction and is relatively stable in the vertical direction. Therefore, making the spare battery box 70 on the first charging seat 30 have a larger space from the side wall of the battery swap compartment 10 can better improve the safety of battery swapping, further improve the rationality of the layout of the battery swap station, and make the battery swap station as compact as possible. In addition, before moving the spare battery box 70, it is necessary to lift the spare battery box 70 to a certain height to separate it from the first charging seat 30, so that the distance between the bottom of the spare battery box 70 on the first charging seat 30 and the top of the spare battery box 70 on the second charging seat 40 will be larger. Therefore, the fifth distance is set to be smaller, which can also save space.

[0050] In this embodiment, if Figure 2 As shown, the silo 14 includes a first vertical side wall 141 and a second vertical side wall 142 . The entrance 11 is provided on the first vertical side wall 141 , and the second vertical side wall 142 is perpendicular to the first vertical side wall 141 and is close to the charger 20 .

[0051] The first air inlet 16 and the first air outlet 17 are detachably connected to the second vertical side wall 142, and the first air outlet 17 is higher than the first air inlet 16. Cold air can enter from the first air inlet 16 at the bottom, and after absorbing the heat in the battery swap compartment 10, the lighter hot air is discharged from the first air outlet 17 at the top. The first air outlet 17 can be higher than the top of the spare battery box 70 on the first charging seat 30, so that the cold air can fully absorb the heat of the spare battery box 70 on the first charging seat 30, and then be discharged from above the battery box. The distance between the first air outlet 17 and the top of the spare battery box 70 on the first charging seat 30 is the first height difference, and the first height difference is 1.1 to 1.5 times the third distance. Therefore, the third distance is smaller and the first height difference is larger. Because the third spacing is relatively small, the cold air entering the battery swap compartment 10 through the first air inlet 16 can fully absorb the heat of the spare battery box 70 on the first charging seat 30, and is unlikely to cause the cold air to rise in the vertical direction near the second vertical side wall 142 and be discharged directly through the first air outlet 17 without fully cooling the spare battery box 70. Based on the principle that hot air flows upward, the large first height difference allows the hot air to be fully discharged.

[0052] In another embodiment, an additional cold air inlet may be provided on the second vertical side wall 142 near the bottom of the charger 20 to cool the charger 20 .

[0053] In this embodiment, if Figure 2 As shown, the housing 14 further includes a third vertical side wall 143 . The third vertical side wall 143 is perpendicular to the first vertical side wall 141 and is close to the third charging seat 50 .

[0054] The third vertical side wall 143 is detachably connected with a second air inlet 18 and a second air outlet 19, and the second air outlet 19 is higher than the second air inlet 18. The second air outlet 19 is higher than the top of the spare battery box 70 on the third charging seat 50, and cold air can enter from the second air inlet 18 below, fully absorb the heat of the spare battery box 70 on the third charging seat 50, and then be discharged from the second air outlet 19. The distance between the second air outlet 19 and the top of the spare battery box 70 on the third charging seat 50 is the second height difference, and the second height difference is 1.1 to 5 times the fourth distance, such as 1.7 times, 2 times, 2.5 times, etc. Since the position of the third charging seat 50 is lower, the position of the second air inlet 18 can be set lower to be closer to the spare battery box 70 on the third charging seat 50 to achieve the purpose of sufficient cooling, that is, Figure 3 As shown, the second air inlet 18 in this embodiment is arranged at the lower part of the warehouse body 14.

[0055] The space above the spare battery box 70 on the third charging station 50 is larger, and the hot air is more likely to flow upward. Therefore, in this embodiment, the second air outlet 19 is set at a higher position, that is, the multiple relationship between the second height difference and the fourth distance is greater than the multiple relationship between the first height difference and the third distance, so that the hot air emitted upward can be fully discharged.

[0056] In this embodiment, the third spacing is equal to the fourth spacing. The second height difference is greater than the first height difference. The second air outlet 19 is positioned higher to prevent hot air that has absorbed heat from the backup battery box 70 on the third charging station 50 from rising to the space above the second air outlet 19 and being unable to be discharged.

[0057] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
