Description

Technical Field

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

[0002] Currently, battery swap stations widely adopt a top-mounted battery swap solution. Its core equipment consists of a drive system, a spreader assembly, a track-based travel mechanism, and a control system. The drive system uses a motor to move the spreader assembly along a predetermined track. This assembly is equipped with a servo-controlled lifting actuator and is compatible with the gripping interfaces of various battery models. During the battery swap operation, the spreader assembly uses a coordinate recognition system to obtain the spatial positioning data of the vehicle's battery swap port. It then drives the assembly along the track path, ultimately completing the highly precise positioning and efficient assembly and disassembly of the battery box from the station to the vehicle's location.

[0003] However, deploying new energy vehicle battery swap stations in limited space, such as urban centers, presents significant challenges in planning the layout of the station's core functional modules. Constrained by densely populated buildings and limited land, the space available for the lifting equipment to access the batteries is severely limited. This directly impacts standard battery loading and unloading procedures, ultimately hindering the station's ability to provide regular battery swap services. Summary of the Invention

Furthermore, some of the above terms may be used to indicate other meanings besides orientation or positional relationships. For example, the term "on" may, in certain circumstances, be used to indicate a dependency or connection relationship. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" are to be interpreted broadly.

In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise specified, "plurality" means two or more.

[0064] In this embodiment, when constructing a new energy vehicle battery swap station in a city center, site conditions significantly restrict the layout of the facilities. The dense distribution of buildings and the small available area significantly restrict the battery operation space of the lifting equipment, making it difficult to fully implement the battery loading and unloading process. This spatial limitation not only affects the reasonable layout of equipment in the battery swap station, but also directly affects the ability of the battery swap station to perform battery replacement operations, ultimately resulting in the inability of the battery swap station to effectively replace the vehicle. Therefore, in order to solve the above problems, the present invention provides a battery swap method.

[0065] The battery swap system can be applied to battery swap methods, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the battery swap system may include a battery swap component 01, a battery box 02, and a battery swap vehicle 03.

[0066] The battery exchange component 01 may include a hoisting unit 11, a rotating unit 12, four battery holders 13, a battery exchange area, and two control units 15. The area projected downward from the moving range of the hoisting unit 11 may include a set area. The battery holder 13, the rotating unit 12, and the battery exchange area may be arranged in sequence within the set area along the first direction. The four battery holders 13 may be divided into two columns along the first direction and into two rows along the second direction. The first direction may be the length direction of the battery holder 13, that is, Figure 2 The left and right directions shown in FIG. 1 and the second direction may be the width direction of the battery holder 13, that is, Figure 2 The up and down directions shown. The rotating unit 12 may include a rotating base 121 and two rotating seats 122. The rotating base 121 rotates around the central axis of the rotating base 121. The rotating seat 122 may be connected to the top of the rotating base 121, and the two rotating seats 122 may be spaced apart. The battery swap area may include a first area and a second area. By limiting the width of the first area and the width of the second area to be respectively greater than the width of the battery box 02 and less than twice the width of the battery box 02, it can be ensured that the battery box 02 on the battery swap vehicle 03 is located in the first area or the second area with high precision and low error, thereby facilitating the lifting unit 11 to disassemble and install the battery box 02 on the battery swap vehicle 03. The width of the first area and the width of the second area are respectively greater than the width of the battery holder 13 and less than twice the width of the rotating seat 122. The distance between the symmetry plane of the first area along the second direction and the symmetry plane of the first row of battery holders 13 along the second direction along the first direction is less than the first set value, so that the first row of battery holders 13 are located in the same row as the first area. The distance between the symmetry plane of the second area along the second direction and the symmetry plane of the second row of battery holders 13 along the second direction along the first direction is less than the second set value, and the distance between the first row of rotating seats 122 and the second row of rotating seats 122 is greater than or equal to the size of the overlapping portion of the first area and the second area along the second direction, thereby reducing the movement path of the hoisting unit along the second direction. In a smaller space, the hoisting unit 11 uses the rotating seat 122 as a transfer platform to achieve the battery swapping action for the battery swapping vehicle 03. Two control units 15 are respectively connected to the hoisting unit 11, one control unit 15 detects the low-power battery box 02 in the first area, and the other detects the low-power battery box 02 in the second area. The control unit 15 can also obtain the position of the battery box 02 on the battery swapping vehicle 03 in the battery swapping area, control the movement path and action of the hoisting unit 11, control the rotation of the rotating unit 12, and obtain the power of the battery box 02 in the battery holder 13. The four battery boxes 02 can be detachably connected to any four of the battery holders 13 and the rotating seat 122.

[0067] A can be the distance between the hanging unit 11 and the battery holder 13 along the third direction. B can be the height of the battery box 02, and the third direction can be the height direction of the battery box 02, that is, Figure 3 In the vertical direction shown, B < A allows for sufficient space in the third direction for the battery box 02 to be removed and installed from the battery holder 13. A < 2*B prevents excessive redundancy in the movement path of the lifting unit 11 along the third direction. L is the length of the battery box 02, and C is the spacing between the first and second areas and any rotating seat 122 along the first direction. 0 ≤ C < T*L, 1 ≤ T ≤ 1.1 limits the distance between the first and second areas and the rotating seat 122, thereby reducing the movement path of the lifting unit along the first direction and, in turn, the size of the lifting unit along the first direction. K is the width of the battery box 02. D is the minimum spacing between the first row of battery holders 13 and one side of the designated area along the second direction. 0 ≤ D < T*K limits the spacing between the first row of battery holders 13 and one side of the designated area along the second direction, thereby reducing the movement path of the lifting unit along the second direction and, in turn, the size of the lifting unit along the second direction. E can be the minimum distance between the second row of battery holders 13 and the set area along one side of the second direction, 0≤E<T*K, so that the distance between the second row of battery holders 13 and the set area along one side of the second direction is limited, which can further reduce the moving path of the hoisting unit along the second direction, thereby reducing the size of the hoisting unit along the second direction. F can be the minimum distance between the first row of battery holders 13 and the second row of battery holders 13, 0≤F<T*K, which limits the first row of battery holders 13 and the second row of battery holders 13. The distance between the first row of battery holders 13 and the second row of battery holders 13 is relatively compact, thereby reducing the moving path of the hoisting unit along the second direction, thereby reducing the size of the hoisting unit along the second direction. The battery swap vehicle 03 includes a vehicle body 31 and a mounting seat 32; the vehicle body 31 and the mounting seat 32 are detachably connected and electrically connected; the battery box 02 and the mounting seat 32 are detachably connected and electrically connected. The battery box 02 can be detachably and electrically connected to the mounting seat 32. The vehicle body 31 can obtain electrical energy through the battery box 02 on the mounting seat 32, thereby driving the battery-swapping vehicle 03 to travel normally on the road.

[0068] like Figure 1 As shown, the battery replacement method may include steps S10 to S20, and steps S10 to S20 may be described in detail below.

[0069] Step S10, based on the low-power battery box 02 on the battery-swapping vehicle 03 arriving at the first area or the second area of ​​the battery-swapping area, obtain the status data of the battery-swapping system. The status data may include the direction of the low-power battery box 02 and the power level of the battery box 02 on the battery holder 13. The battery-swapping area may include a first area and a second area, and the width of the first area and the width of the second area are respectively greater than the width of the battery box 02 and less than twice the width of the battery box 02. By limiting the width of the first area and the width of the second area to be greater than the width of the battery box 02 and less than twice the width of the battery box 02, it can be ensured that when the battery box 02 on the battery-swapping vehicle 03 is located in the first area or the second area, the control unit 15 can better obtain the position of the battery box 02 on the battery-swapping vehicle 03, thereby facilitating the lifting unit 11 to disassemble and install the battery box 02 on the battery-swapping vehicle 03.

[0070] Step S20, based on the state data being in the first state, the hoisting unit 11 moves the low-power battery box 02 to the rotating seat 122 of the rotating unit 12, and then moves the battery box 02 in the battery holder 13 to a position where it is detachably connected and electrically connected to the mounting seat 32 of the battery-swapping vehicle 03, thereby completing the battery-swapping operation for the battery-swapping vehicle 03 and providing the battery-swapping vehicle 03 with a longer range. Among them, the first state may include the direction of the battery box 02 being the same as the direction of the low-power battery box 02 on the battery-swapping vehicle 03, and the power of the battery box 02 in the battery holder 13 being greater than or equal to the set power. The set power may be a fixed value, which may be 80% or 90% of the ratio of the full power of the battery box 02 to the current power of the battery box 02, or a variable value. The battery holder 13, the rotating seat 122, and the battery-swapping area are sequentially spaced along the first direction. The first row of rotating seats 122 and the second row of rotating seats 122 are spaced apart along the second direction. This prevents the battery boxes 02 in the two rows from colliding when both the first and second rows of rotating seats 122 have battery boxes 02, causing damage to the battery boxes 02. The distance between the symmetry plane of the first area in the second direction and the symmetry plane of the battery holder 13 in the first row in the second direction is less than a first set value, which can be 10cm to 15cm. This makes it easier for the hoisting unit 11 to install and remove the battery boxes 02. The distance between the symmetry plane of the second area in the second direction and the symmetry plane of the second row of battery holders 13 in the second direction is less than a second set value, which can be the same as the first set value. The spacing between the first row of rotating seats 122 and the second row of rotating seats 122 is greater than or equal to the dimension of the overlapping portion of the first and second areas along the second direction. Thus, in a relatively small space, the hoisting unit 11 uses the rotating seat 122 as a transfer platform to achieve battery swapping for the battery swapping vehicle 03.

[0071] In this embodiment, step S20 may include step S21, and step S21 may include steps S211 to S213. Steps S211 to S213 will be described in detail below.

[0072] In step S211, based on the state data being in the first state, the hoisting unit 11 may move the low-power battery box 02 on the battery-swapping vehicle 03 to the first row of rotating seats 122, thereby removing the battery box 02 on the battery-swapping vehicle 03 and preparing for the subsequent installation of a battery box 02 with a power level greater than or equal to the set level. The first state may also include the low-power battery box 02 of the battery-swapping vehicle 03 being located within the first area.

[0073] In step S212, the low-power battery box 02 of the battery-swapping vehicle 03 is moved to the first row of rotating seats 122 based on the hoisting unit 11. The rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the hoisting unit 11 grabs the battery box 02 on the first row and second column of battery holders 13. After the rotating base 121 rotates 180°, the first row of rotating seats 122 and the first row of battery holders 13 are located in the same row. While the rotating base 121 rotates 180° around the central axis of the rotating base 121, the hoisting unit 11 grabs the battery box 02 on the first row and second column of battery holders 13. In this way, the overall battery-swapping efficiency can be improved by the simultaneous operation of the rotating base 121 and the hoisting unit 11.

[0074] In step S213, the rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the lifting unit 11 grabs the battery box 02 on the first row and second column battery holder 13. The lifting unit 11 moves the battery box 02 on the first row and second column battery holder 13 to a detachable and electrically connected position with the mounting seat 32, thereby completing the battery replacement operation of the battery replacement vehicle 03.

[0075] In this embodiment, the battery replacement method may further include step S22, which may include steps S221 and S222. Steps S221 and S222 are described in detail below. Step S22 is performed after step S10 is completed.

[0076] In step S221, based on the state data being in the first state, the hoisting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 to the first row of rotating seats 122. The first state also includes the low-power battery box 02 being located in the second area.

[0077] In step S222, the hoisting unit 11 moves the low-charge battery box 02 of the battery-swapping vehicle 03 to the first row of rotating seats 122. The hoisting unit 11 moves the battery box 02 on the second row, second column battery seat 13 to a position where it is detachable and electrically connected to the mounting seat 32, thereby completing the battery-swapping operation for the battery-swapping vehicle 03. In this way, the low-charge battery box 02 of the battery-swapping vehicle 03 is directly moved to the first row of rotating seats 122 without rotating the rotating base 121 around the central axis of the rotating base 121, thereby reducing wear on the rotating base 122.

[0078] In this embodiment, the battery replacement method may further include step S23, which may include steps S231 to S235. Steps S231 to S235 are described in detail below. Step S23 is performed after step S10 is completed.

[0079] In step S231, based on the status data being in the second state, the hoisting unit 11 may move the battery box 02 in the second row, second column battery holder 13 into the first row rotating seat 122, so that the battery box 02 with a power greater than or equal to the set power is given priority and moved to be installed with the battery swap vehicle 03, thereby ensuring the mileage of the battery swap vehicle 03. The second state may include that the direction of the battery box 02 is the same as the direction of the low-power battery box 02 on the battery swap vehicle 03, the low-power battery box 02 on the battery swap vehicle 03 is located in the first area, the power of the battery box 02 in the first row, second column battery holder 13 is less than the set power, and the power of the battery box 02 in the second row, second column battery holder 13 is greater than or equal to the set power.

[0080] In step S232, the battery box 02 in the second row and second column of the battery holder 13 is moved to the first row of the rotating seat 122 based on the hoisting unit 11. The rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the hoisting unit 11 moves to grab the low-power battery box 02 of the battery-exchange vehicle 03. In this way, the simultaneous operation of the rotating base 121 and the hoisting unit 11 can improve the overall battery-exchange efficiency.

[0081] In step S233, the rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the lifting unit 11 moves to grab the low-power battery box 02 of the battery-swapping vehicle 03. The lifting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 to the first row of rotating seats 122. In this way, the battery box 02 on the battery-swapping vehicle 03 is disassembled, preparing for the subsequent installation of a battery box 02 with a power greater than or equal to the set power.

[0082] Step S234, based on the lifting unit 11, the low-power battery box 02 of the battery-swapping vehicle 03 is moved to the first row of rotating seats 122, and the rotating base 121 is rotated 180° around the central axis of the rotating base 121, so that the battery box 02 on the first row of rotating seats 122 is in the same direction as the mounting seat 32.

[0083] Step S235, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, the lifting unit 11 moves the battery box 02 on the first row of rotating seats 122 to a detachable and electrically connected connection with the mounting seat 32, thereby completing the battery replacement action for the battery replacement vehicle 03.

[0084] In this embodiment, the battery replacement method may further include step S24, which may include steps S241 to S243. Steps S241 to S243 are described in detail below. Step S24 is performed after step S10 is completed.

[0085] Step S241, based on the status data being in the third state, the hoisting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 into the second row of rotating seats 122, so that the battery box 02 on the battery-swapping vehicle 03 is first disassembled to prepare for the subsequent installation of a battery box 02 with more sufficient power. Among them, the third state includes that the direction of the battery box 02 is the same as the direction of the low-power battery box 02 on the battery-swapping vehicle 03, the low-power battery box 02 of the battery-swapping vehicle 03 is located in the second area, the power of the battery box 02 in the first row and second column battery seat 13 is less than the set power, and the power of the battery box 02 in the second row and second column battery seat 13 is greater than or equal to the set power. The battery box 02 in the second row and second column has more sufficient power and is closer to the rotating seat 122, so that the hoisting unit 11 can reduce the moving time when replacing the battery box 02 on the battery-swapping vehicle 03, thereby improving the overall battery-swapping efficiency.

[0086] In step S242, the low-power battery box 02 of the battery-swapping vehicle 03 is moved to the second row of rotating seats 122 based on the hoisting unit 11. The rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the hoisting unit 11 grabs the battery box 02 on the second row and second column of the battery seat 13. In this way, the simultaneous operation of the rotating base 121 and the hoisting unit 11 can improve the overall battery-swapping efficiency.

[0087] In step S243, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121 and the lifting unit 11 grabbing the battery box 02 on the second row and second column battery holder 13, the lifting unit 11 moves the battery box 02 on the second row and second column battery holder 13 to a detachable and electrically connected position with the mounting seat 32, thereby completing the battery replacement action for the battery replacement vehicle 03.

[0088] In this embodiment, the status data also includes the number of battery swapping vehicles 03 in the waiting area. The waiting area can be set outside the set area and can be used to accommodate battery swapping vehicles 03 waiting for battery swapping. When there are no battery swapping vehicles 03 in the battery swapping area, the battery swapping vehicles 03 in the waiting area can enter the battery swapping area in turn to complete the battery swapping.

[0089] The battery replacement method may further include step S25, which may include steps S251 to S258. Steps S251 to S258 are described in detail below. Step S25 is performed after step S20 is completed.

[0090] In step S251, the battery box 02 in the battery holder 13 is moved to a detachable connection with the mounting seat 32 of the battery swap vehicle 03 based on the hoisting unit 11 to obtain the status data of the battery swap system.

[0091] Step S252, based on the status data being in the fourth state, the hoisting unit 11 moves the battery box 02 in the first row, second column, close to the battery holder 13, to the first row, first column, rotating seat 122. The fourth state includes that there are no low-power battery boxes 02 in the first area and the second area, there are no battery-swapping vehicles 03 in the waiting area, the power of the battery box 02 in the first row, second column, battery holder 13 is less than the set power, and the first row, first column, battery holder 13 is greater than or equal to the set power. When there are no low-power battery boxes 02 in the first area and the second area, the hoisting unit 11 can interchange the positions of the battery box 02 in the first row, second column, battery holder 13 and the battery box 02 in the first row, first column, battery holder 13, so that when the low-power battery box 02 enters the first area and the second area, the battery box 02 in the second column is closer to the rotating seat 122, thereby reducing the battery-swapping steps and improving the battery-swapping efficiency of the battery-swapping vehicle 03.

[0092] In step S253, the battery box 02 in the first row and second column close to the battery holder 13 is moved to the first row of rotating seats 122 based on the lifting unit 11. The rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the lifting unit 11 moves to grab the battery box 02 in the first row and first column of the battery holder 13. In this way, the simultaneous operation of the rotating base 121 and the lifting unit 11 can improve the overall battery replacement efficiency.

[0093] In step S254 , the rotatable base 121 rotates 180° around the central axis of the rotatable base 121 and the hoisting unit 11 moves to grab the battery box 02 in the first row and first column of the battery holder 13 , and the hoisting unit 11 moves the battery box 02 in the first row and first column of the battery holder 13 to the first row of the rotatable base 122 .

[0094] In step S255 , the battery box 02 in the first row and first column of the battery holder 13 is moved to the first row of the rotating holder 122 by the hoisting unit 11 , and the rotating base 121 is rotated 180° around the central axis of the rotating base 121 .

[0095] Step S256, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, the lifting unit 11 moves the battery box 02 in the first row of rotating seats 122 to the first row and first column of battery seats 13, and moves the battery box 02 with less than the set power to the first row and first column of battery seats 13. When there are battery boxes 02 with low power in the first area and the second area, the battery box 02 in the second column with more than the set power is preferentially selected, thereby reducing the steps of battery replacement for the battery replacement vehicle 03.

[0096] In step S257, based on the lifting unit 11, the battery box 02 in the first row of rotating seats 122 is moved to the first row and first column of battery seats 13, and the rotating base 121 is rotated 180° around the central axis of the rotating base 121, so that the direction of the first row and second column of battery seats 13 is the same as the direction of the battery box 02 in the first row of rotating seats 122, thereby preparing for subsequent steps.

[0097] In step S258, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, the hoisting unit 11 moves the battery box 02 in the first row of rotating seats 122 to the first row and second column of battery holders 13. The position of the battery box 02 is optimized by the rotation of the hoisting unit 11 and the rotating base 121. When there is no battery swapping vehicle 03 in the battery swapping area, the battery swapping system automatically adjusts the arrangement order of the battery box 02, and swaps the position of the battery box 02 in the first row and second column of battery holders 13 with the position of the battery box 02 in the first row and first column of battery holders 13, so that the battery box 02 with a power greater than the set power is located on the battery holder 13 in the second column. The battery holder 13 in the second column is closer to the rotating base 122. When swapping batteries, the moving path of the hoisting unit 11 is shorter and there are fewer obstacles, thereby improving the efficiency of subsequent battery swapping steps.

[0098] In this embodiment, the battery replacement method may further include step S26, which will be described in detail below. Step S26 is performed after step S10 is completed.

[0099] Step S26, based on the state data being in the fifth state, the hoisting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 to the rotating seat 122 of the rotating unit 12, and then moves the battery box 02 to a position where it is detachably connected and electrically connected to the mounting seat 32 of the battery-swapping vehicle 03, thereby completing the battery-swapping operation on the battery-swapping vehicle 03. Among them, the fifth state may include the direction of the battery box 02 being opposite to the direction of the low-power battery box 02 on the battery-swapping vehicle 03. The battery-swapping operation on the battery-swapping vehicle 03 may also be completed based on the different directions in which the battery box 02 on the battery-swapping vehicle 03 arrives in the battery-swapping area.

[0100] In this embodiment, step S26 may include step S261, and step S261 may include steps S2611 to S2614, which will be described in detail below. Step S2611 is executed after step S10 is completed.

[0101] In step S2611, based on the state data being in the fifth state, the hoisting unit 11 moves the low-charge battery box 02 of the battery-swapping vehicle 03 onto the first row of rotating seats 122, thereby removing the battery box 02 from the battery-swapping vehicle 03 and preparing for the subsequent installation of a battery box 02 with a relatively sufficient charge. The fifth state also includes the low-charge battery box 02 of the battery-swapping vehicle 03 being located within the first area and the charge of the battery box 02 in the battery seat 13 being greater than or equal to the set charge.

[0102] In step S2612, the hoisting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 onto the first row of rotating seats 122, and the hoisting unit 11 moves the battery box 02 in the second row, second column of the battery holder 13 into the second row of rotating seats 122. Since the battery box 02 in the first row, second column of the battery holder 13 is blocked by the battery box 02 on the first row of rotating seats 122, the battery box 02 in the second row, second column of the battery holder 13 is moved into the second row of rotating seats 122, thereby increasing the speed of battery swapping, and then proceeding with subsequent operations.

[0103] Step S2613, based on the lifting unit 11, the battery box 02 in the second row and second column battery seat 13 is moved to the second row rotating seat 122, and the rotating base 121 of the rotating unit 12 is rotated 180° around the central axis of the rotating base 121, so that the direction of the battery box 02 in the first row rotating seat 122 is the same as the direction of the mounting seat 32, so as to better perform subsequent operation steps.

[0104] Step S2614, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, the battery box 02 in the first row of rotating seats 122 is moved to a detachable and electrically connected connection with the mounting seat 32, thereby completing the battery replacement action of the battery replacement vehicle 03.

[0105] In this embodiment, step S26 may include step S262, and step S262 may include steps S2621 to S2625. Steps S2621 to S2625 are described in detail below. Step S262 is performed after step S10 is completed.

[0106] Step S2621, based on the status data being in the fifth state, the hoisting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 to the second row of rotating seats 122, and disassembles the battery box 02 on the vehicle to prepare for the subsequent installation of a battery box 02 with more sufficient power.

[0107] Step S2622, based on the lifting unit 11, the low-power battery box 02 of the battery swap vehicle 03 is moved to the second row of rotating seats 122, and the lifting unit 11 moves the battery box 02 in the first row and second column of battery seats 13 to the first row of rotating seats 122. Since there is a battery box 02 on the second row of rotating seats 122, the battery box 02 in the first row and second column of battery seats 13 is moved to the first row of rotating seats 122, thereby preparing for subsequent steps.

[0108] Step S2623, based on the lifting unit 11, the battery box 02 in the first row and second column battery seat 13 is moved to the first row rotating seat 122, and the rotating base 121 of the rotating unit 12 is rotated 180° around the central axis of the rotating base 121, so that the direction of the low-power battery box 02 of the battery-exchange vehicle 03 in the first row rotating seat 122 is the same as the direction of the first row and second column battery seat 13, so as to better carry out the subsequent battery-exchange steps.

[0109] Step S2624, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, the lifting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 in the first row of rotating seats 122 to the first row and second column of battery seats 13, thereby reserving space in the first row of rotating seats 122, thus preparing for the subsequent battery-swapping steps.

[0110] In step S2625, the lifting unit 11 moves the low-power battery box 02 of the battery-swapping vehicle 03 in the first row of rotating seats 122 to the first row and second column of battery seats 13. The lifting unit 11 moves the battery box 02 in the second row of rotating seats 122 to a position where it can be detachably and electrically connected to the mounting seat 32, thereby completing the battery-swapping operation for the battery-swapping vehicle 03.

[0111] In this embodiment, if Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the battery exchange system is applied to any one of the battery exchange methods in the above embodiments, and the battery exchange system may include a battery exchange component 01, a battery box 02, and a battery exchange vehicle 03.

[0112] The battery exchange assembly 01 may include a hoisting unit 11, a rotating unit 12, four battery holders 13, a battery exchange area, and two control units 15. The area projected downward from the moving range of the hoisting unit 11 may include a set area. The battery holder 13, the rotating unit 12, and the battery exchange area may be arranged in sequence within the set area along the first direction. The four battery holders 13 may be divided into two columns along the first direction and into two rows along the second direction. The rotating unit 12 may include a rotating base 121 and two rotating seats 122. The rotating base 121 rotates around the central axis of the rotating base 121. The rotating seat 122 may be connected to the top of the rotating base 121, and the two rotating seats 122 may be arranged at intervals. The battery exchange area may include a first area and a second area. The width of the first area and the width of the second area are respectively greater than the width of the battery holder 13 and less than twice the width of the rotating seat 122. The distance between the symmetry plane of the first area along the second direction and the symmetry plane of the first row of battery holders 13 along the second direction along the first direction is less than a first set value. The distance between the symmetry plane of the second area along the second direction and the symmetry plane of the second row of battery seats 13 along the second direction along the first direction is less than the second set value. By limiting the width of the first area and the width of the second area to be respectively greater than the width of the battery box 02 and less than twice the width of the battery box 02, it is convenient for the hoisting unit 11 to disassemble and install the battery box 02 on the battery swap vehicle 03. The spacing between the first row of rotating seats 122 and the second row of rotating seats 122 is greater than or equal to the size of the overlapping part of the first area and the second area along the second direction, thereby reducing the movement path of the hoisting unit along the second direction. In a smaller space, the hoisting unit 11 uses the rotating seat 122 as a transfer platform to realize the battery swap action of the battery swap vehicle 03. Two control units 15 are respectively connected to the hoisting unit 11, one control unit 15 detects the low-power battery box 02 in the first area, and the other detects the low-power battery box 02 in the second area. The control unit 15 can obtain the position of the battery box 02 on the battery swap vehicle 03 in the battery swap area, control the movement path and movement of the hoisting unit 11, control the rotation of the rotating unit 12, and obtain the power level of the battery box 02 in the battery holder 13. The four battery boxes 02 can be detachably connected to any four of the battery holders 13 and the rotating holder 122.

[0113] A can be the distance between the hanging unit 11 and the battery holder 13 along the third direction. B can be the height of the battery box 02, and the third direction can be the height direction of the battery box 02, that is, Figure 3In the vertical direction shown, B < A allows for sufficient space in the third direction for the lifting unit 11 to remove and install the battery box 02 and the battery holder 13. A < 2*B can avoid excessive redundancy in the movement path of the lifting unit 11 along the third direction. L can be the length of the battery box 02, and C is the spacing between the first and second areas and any rotating seat 122 along the first direction. 0 ≤ C < T*L, 1 ≤ T ≤ 1.1 limits the distance between the first and second areas and the rotating seat 122, thereby reducing the movement path of the lifting unit along the first direction and, in turn, reducing the size of the lifting unit along the first direction. K can be the width of the battery box 02. D can be the minimum spacing between the first row of battery holders 13 and one side of the set area along the second direction. 0 ≤ D < T*K limits the spacing between the first row of battery holders 13 and one side of the set area along the second direction, thereby reducing the movement path of the lifting unit along the second direction. E can be the minimum distance between the second row of battery holders 13 and the set area along the second direction, 0≤E<T*K, so that the distance between the second row of battery holders 13 and the set area along the second direction is limited, which can further reduce the moving path of the hoisting unit along the second direction, thereby reducing the size of the hoisting unit along the second direction. F can be the minimum distance between the first row of battery holders 13 and the second row of battery holders 13, 0≤F<T*K, so that the distance between the first row of battery holders 13 and the second row of battery holders 13 is more compact, thereby reducing the size of the set area along the second direction, thereby reducing the size of the hoisting unit along the second direction. The battery swap vehicle 03 includes a vehicle body 31 and a mounting seat 32; the vehicle body 31 is detachably connected and electrically connected to the mounting seat 32; the battery box 02 is detachably connected and electrically connected to the mounting seat 32. The battery box 02 can be detachably connected and electrically connected to the mounting seat 32, and the vehicle body 31 can obtain electrical energy through the battery box 02 on the mounting seat 32, thereby driving the battery swap vehicle 03 to travel normally on the road.

[0114] In other embodiments, the battery exchange system may further include a power delivery vehicle 14, which is detachably connected to the battery holder 13. In this way, the battery box 02 components and battery holders 13 in the set area are transported and replaced by the power delivery vehicle 14, and no charger is installed in the set area, thereby reducing the construction cost of the battery exchange system. G is the distance between any row of battery holders 13 and the rotating holder 122 along the second direction, 0≤G<T*L, which can further reduce the movement path of the hoisting unit along the second direction, making the battery holder 13 and the rotating holder 122 more compact. 0≤G<T*K, which limits the distance between the battery holder 13 and the rotating holder 122, making the set area more compact. 0≤M<T*K, M is the distance between adjacent battery holders 13 in the first row, 0≤N<T*K, N is the distance between adjacent battery holders 13 in the second row, thus limiting the distance between adjacent battery holders 13 in the first row and adjacent battery holders 13 in the second row, reducing the movement path of the hoisting unit along the first direction, and thereby reducing the size of the hoisting unit along the first direction. The distance in the second direction between the plane of symmetry of the first row of rotating seats 122 and the plane of symmetry of the first row of battery holders 13 along the second direction is less than a third set value; the third set value may be the same as the first set value. The distance in the second direction between the plane of symmetry of the second row of rotating seats 122 and the plane of symmetry of the second row of battery holders 13 along the second direction is less than a fourth set value; the fourth set value may be the same as the first set value.

[0115] The hoisting unit 11 may include a trolley guide rail 111, a trolley portion 112, a trolley guide rail, a trolley body 31, a gripping portion 113, and a support portion 114. One end of the support portion 114 may be spaced apart from the rotating unit 12 and the battery holder 13, respectively, and the other end may extend away from the battery holder 13 along a third direction. The trolley guide rail 111 may be connected to the end of the support portion 114 away from the battery holder 13, so that the support portion 114 provides support for the trolley guide rail 111. The longitudinal direction of the trolley guide rail 111 may be parallel to the first direction. The trolley portion 112 may be slidably connected to the trolley guide rail 111, and the trolley portion 112 may move along the longitudinal direction of the trolley guide rail 111. The trolley guide rail may be connected to the trolley portion 112, and the longitudinal direction of the trolley guide rail may be parallel to the second direction. The trolley body 31 may be slidably connected to the trolley guide rail, and the trolley body 31 may move along the longitudinal direction of the trolley guide rail. The gripping portion 113 can be drivably connected to the trolley body 31, and the trolley body 31 can drive the gripping portion 113 to move in the third direction. This arrangement allows the gripping portion 113 to be raised and lowered in the third direction to grasp the battery box 02 assembly. The battery box 02 assembly can then be moved by moving the trolley body 31 in the second direction and the carriage portion 112 in the first direction. The set area is the area through which the trolley guide rail moves from one end of the carriage guide rail 111 to the other end of the carriage guide rail 111.
