Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle technology, and in particular to a battery swap station, a battery swap system, and a battery swap method. Background Art

[0002] In the prior art, battery swap stations usually adopt a layout structure of two rows and multiple columns of battery holders, with channels set between or on both sides of the two rows of battery holders, and empty spaces for battery holders reserved therein as turnover positions. This layout uses channels to achieve horizontal movement of the battery box (there is enough space above the battery box to achieve up and down movement of the battery box). When it is necessary to replace or reconfigure the battery box on a battery holder in the array, the operation process is usually to use a lifting unit to remove the battery box on the battery swap vehicle from the mounting seat, and then transfer it through the channel and temporarily place it in a preset turnover position. After completing this step, the lifting unit can perform subsequent operations, such as placing the battery box in the battery swap station on the mounting seat, or moving the battery box at the turnover position to other designated locations. The entire physical handling process of the battery box is highly dependent on the movement of the lifting unit in the channel and the picking and placement operations between different locations in the battery swap station.

[0003] However, this existing layout structure leads to a significant technical problem: when the battery box is replaced or repositioned, its movement path is usually long and time-consuming. When a battery box that is not located at the turnover position needs to be replaced (which is the vast majority of cases), the hoisting unit must perform a long-distance movement process. Specifically, the hoisting unit first needs to move to the original position of the target battery box, pick up the battery box, and then carry it to the turnover position and put it down. After that, if a new battery box needs to be placed, the hoisting unit needs to move a long distance again (possibly returning to the original area or to the new battery box storage point) to pick up the new battery box, and move a long distance again to place it at the target position. In this process, both the battery box itself and the hoisting unit need to perform multiple reciprocating long-distance displacements in the channel, resulting in a significant increase in operation time, mainly in the time spent on the hoisting unit carrying the battery box for a long distance in the channel, reducing the operating efficiency of the overall system.

[0029] In this embodiment, during the operation of the battery exchange component 01, the hoisting unit 11 needs to cover a long distance when moving the battery box 02, which significantly increases the time consumption of the battery exchange process. In the existing layout design, when the hoisting unit 11 performs the battery box 02 access operation, it must move the battery box 02 from the original position (such as the first battery holder 12 in the first placement area or the second placement area) to the turnover position or battery exchange area. This path usually involves long-distance displacement across the mobile channel and multiple battery holders, which requires the hoisting unit 11 to move a long distance and has low efficiency. This embodiment discloses a battery exchange station, such as Figure 1As shown, the battery swap station includes a battery swap component 01 and a battery box 02. The battery swap component 01 includes a hoisting unit 11, a plurality of first battery holders 12, and a plurality of second battery holders 13. The area projected downward from the moving range of the hoisting unit 11 includes a set area. The set area includes a first area, a second area, a moving channel, and a battery swap area. The first area, the moving channel, and the second area are arranged in sequence along the first direction, and the first direction may be the width direction of the hoisting unit 11. The first area includes a first placement area and a first turnover area. The second area includes a second placement area and a second turnover area. The first placement area, the first turnover area, and the battery swap area are arranged in sequence along the second direction, and the second direction may be from the first side (left) in the length direction of the hoisting unit 11 to the second side (right) in the length direction of the hoisting unit 11, that is, Figure 1 As shown from left to right. The second placement area, the second turnover area, and the battery exchange area are arranged in sequence along the second direction. Two rows and multiple columns of first battery holders 12 can be arranged in the first placement area. Two rows and multiple columns (the first direction is rows, the second direction is columns) of first battery holders 12 can be arranged in the second placement area. Part of the two rows and multiple columns of first battery holders 12 are arranged in the first placement area. Another part of the two rows and multiple columns of first battery holders 12 are arranged in the second placement area, and the first battery holders 12 in the first placement area and the second placement area add up to all the first battery holders 12. A row of second battery holders 13 can be arranged in the first turnover area and / or the second turnover area, wherein all the second battery holders 13 are arranged in a row. In other embodiments, the hoisting unit 11 includes a trolley guide rail 111, a trolley body 112, a trolley guide rail 113, a trolley body 114, a grabbing portion 115 and a supporting portion 116. The trolley body 112 can be slidably connected to the trolley guide rail 111, and the trolley guide rail 113 can be connected to the trolley body 112. The trolley body 114 can be slidably connected to the trolley guide rail 113. The trolley unit can move along the width direction of the battery exchange component 01. A planar positioning system is formed by the lateral movement of the trolley body 114 and the longitudinal movement of the trolley body 112, so as to achieve precise position adjustment of the transport component in two-dimensional space. The grabbing portion 115 can be detachably connected to the trolley body 114 to achieve grabbing of the battery box 02. The supporting portion 116 can be connected to the trolley guide rail 111 to support the hoisting unit 11.

The first battery holder 12 and the second battery holder 13 are each used to place battery boxes 02. B<A<2×B. In this case, the battery box 02 cannot be moved above other battery boxes 02. By limiting the spacing between the hoisting unit 11 and the first battery holder 12 and the second battery holder 13 along the third direction, the battery swap assembly 01 can be more compact in the third direction. Here, A is the spacing between the hoisting unit 11 and the first battery holder 12 and the second battery holder 13 along the third direction, where the third direction can be the height direction of the hoisting unit 11.

In this way, a four-row, multi-column layout of battery holders can be formed, and by precisely controlling the spatial spacing (such as C, D, F, G, H, I, and J, while preventing the battery box 02 from moving through the gaps between the battery boxes 02, ensuring that the operating space can complete the battery swap, and making the battery swap station more compact), the hoisting unit 11 can complete the access and movement of the battery box 02 within a short distance, thereby reducing the length of the displacement path of the battery box 02, and ultimately solving the time-consuming problem caused by the battery box 02 moving over a long distance through the hoisting unit 11, thereby improving the battery swap efficiency. In other embodiments, 0≤C<T×K, so that the battery swap station can be more compact in structure while ensuring battery swapping, thereby improving the battery swap efficiency.

[0031] In this embodiment, the battery swap assembly 01 includes at least three columns of first battery holders 12. Each column of first battery holders 12 is arranged sequentially along the second direction. By providing at least three columns of battery holders, the battery swap assembly 01 can increase the number and arrangement density of the first battery holders 12, thereby storing more battery boxes 02, while controlling the overall occupied area through orderly arrangement.

[0032] In this embodiment, the two second battery holders 13 can be arranged in the first turnover area or the two second battery holders 13 can be arranged in the second turnover area, so that the space of the first turnover area or the second turnover area can be efficiently utilized, making the layout more compact.

The battery swap component 01 includes four second battery holders 13, and two second battery holders 13 are arranged in the first turnover area and the second turnover area.

[0033] In this embodiment, Z≥2. Wherein, Z is the number of second battery holders 13. By increasing the number of second battery holders 13, the temporary storage capacity of the battery box 02 can be increased, thereby enhancing the battery replacement capability. The battery replacement component 01 includes two second battery holders 13, and the two second battery holders 13 can be both arranged in the first turnover area or the two second battery holders 13 are both arranged in the second turnover area.

The battery replacement component 01 includes four second battery holders 13, and two second battery holders 13 are arranged in the first turnover area and the second turnover area.

[0035] In this embodiment, the battery exchange component 01 also includes a control unit 15. The control unit 15 is spaced apart from the second battery holder 13. The control unit 15 can be arranged in the first turnover area or the second turnover area, and there can be one or two control units 15. Part of the second battery holder 13 can be arranged in the first turnover area, and the other part of the second battery holder 13 can be arranged in the second turnover area. Z+S=4. R>B. Among them, Z is the number of second battery holders 13, Z=2, and S is the number of control units 15. R is the distance between the top of the control unit 15 and the hoisting unit 11 along the third direction. The control unit 15 is set to obtain the power status of the battery box 02 in the first battery holder 12 and the second battery holder 13 and control the movement of the hoisting unit 11, and R>B ensures that the battery box 02 can pass through the top of the control unit 15 unimpeded under the drive of the hoisting unit 11.

[0036] In this embodiment, 2≤Z<4. The large number of second battery holders 13 can enable more battery replacement control methods during battery replacement, thereby providing more battery replacement control options, facilitating the selection of the optimal method, and improving efficiency.

[0037] In this embodiment, the second battery holder 13 can be arranged in the first turnover area near the moving channel and / or the second battery holder 13 can be arranged in the second turnover area near the moving channel. By arranging the second battery holder 13 near the moving channel, the battery box 02 is prevented from being blocked when moving, thereby improving operational efficiency.

[0038] This embodiment discloses a battery exchange system, which includes a battery exchange station of any of the above embodiments, and the battery exchange system also includes: a battery exchange vehicle 03, and the battery exchange vehicle 03 includes a vehicle body 31 and a mounting seat 32. The vehicle body 31 can be connected to the mounting seat 32. The mounting seat 32 can be detachably connected to the battery box 02. The lifting unit 11 can be used to disassemble and assemble the battery box 02 on the mounting seat 32 in the battery exchange area. X also includes the sum of the number of the first battery seat 12, the second battery seat 13 and the mounting seat 32. When the battery exchange vehicle 03 arrives at the battery exchange area, the distance between the battery exchange vehicle 03 and any second battery seat 13 along the second direction is equal to C. By limiting the sum of the number of the first battery holder 12, the second battery holder 13 and the mounting seat 32, the battery swap system can have enough idle first battery holders 12 or second battery holders 13 or mounting seats 32, so that the battery swap system can realize the battery swap of the battery swap vehicle 03. At the same time, the battery box 02 can be accessed and moved within a short distance through the hoisting unit 11, thereby reducing the length of the displacement path of the battery box 02, and ultimately solving the time-consuming problem caused by the long distance covered by the hoisting unit 11 when moving the battery box 02, thereby improving the battery swap efficiency. In other embodiments, such as Figure 2 As shown, the battery exchange system also includes a power delivery vehicle 14, which provides a battery box 02 for the battery exchange station.

[0039] This embodiment discloses a battery replacement method, which can be applied to the battery replacement system of any of the above embodiments. The battery replacement method includes steps S10 to S30, and each step is described in detail as follows:

[0040] In step S10, upon the battery swap vehicle 03 arriving at the battery swap area, the status data of the battery swap system may be obtained, including the power level of the battery box 02 in the first battery holder 12, the power level of the battery box 02 in the second battery holder 13, and the position of the mounting base 32 of the battery swap vehicle 03 within the battery swap area.

[0041] In step S20, based on the fact that there is no battery box 02 in the two second battery holders 13 and there is a battery box 02 with a power greater than the set power in the first battery holder 12, the battery box 02 with low power on the battery-swapping vehicle 03 can be moved to the second battery holder 13 away from the mounting seat 32.

[0042] In step S30, based on moving the low-power battery box 02 on the battery-swapping vehicle 03 to the second battery holder 13 away from the mounting seat 32, a battery box 02 with a power greater than the set level in the first battery holder 12 can be moved to the mounting seat 32 of the battery-swapping vehicle 03 through the moving channel. In this way, the battery box 02 movement step can be executed based on the status data, and short-distance operation can be achieved through a four-row, multi-column layout, thereby reducing the displacement length of the battery box 02 driven by the hoisting unit 11, ultimately solving the problem of long battery replacement time and improving efficiency.

[0043] In this embodiment, the battery replacement method further includes steps S40 and S50. After step S30 is completed, steps S40 and S50 can be performed in sequence. The details of each step are as follows:

[0044] In step S40, the number of battery swap vehicles 03 in the waiting area can be obtained based on moving a battery box 02 with a capacity greater than the set capacity in the first battery holder 12 to the mounting seat 32 of the battery swap vehicle 03. The waiting area is set on the side of the battery swap area away from the first area.

[0045] In step S50, based on the absence of a battery-swapping vehicle 03 in the waiting area, the battery box 02 with low power in the second battery holder 13 can be moved to the first battery holder 12 away from the mobile channel and / or the battery-swapping area, and the battery box 02 with a power level higher than the set level in the first battery holder 12 can be moved to the first battery holder 12 close to the mobile channel and / or the battery-swapping area. This can optimize the position of the battery box 02 when there is no battery-swapping vehicle 03, thereby reducing the time required for subsequent battery-swapping operations and improving the battery-swapping efficiency of the battery-swapping station.

[0046] 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.
