Description

Technical Field

[0002] In the field of battery swapping technology for transportation vehicles, the vehicles have energy storage space that accommodates multiple battery boxes. To facilitate battery swapping operations, dedicated swapping channels are reserved above the battery boxes within the energy storage space, or between adjacent battery boxes, for moving the battery boxes. When a battery box in the energy storage space is low on power, it can be moved out of the space using the swapping channel. Then, a battery box with more power is moved into its discharge seat within the energy storage space via the same swapping channel. However, the existence of the swapping channels results in an excessively large volume of energy storage space on the transportation vehicle, and the dispersed arrangement of the battery boxes reduces the energy density and space utilization of the energy storage space.

[0062] The inventors of this application have discovered that when multiple battery boxes 30 in the energy storage space are arranged densely and the energy density of the energy storage space is high, the battery boxes 30 cannot move from the top of the multiple battery boxes 30 or the gaps between the battery boxes 30, making it difficult to swap the batteries 30 in the second row of battery boxes 30 whose power is lower than the preset value.

[0063] Example 1:

[0064] The battery swapping method for the transportation vehicle in this embodiment involves a battery swapping system including multiple battery boxes 30, energy storage components 10, and battery swapping stations. For example... Figures 1-5As shown, the battery box 30 serves as an energy storage component to power the transportation vehicle. The energy storage assembly 10 includes an energy storage unit 11 (including multiple discharge seats 111) and a battery swapping unit 12 (including a transport module 121 and a rotation module 122, the rotation module 122 including a rotating base 1222 and two rotating seats 1221). The movement range of the transport module 121 and the space enclosed by the set plane include an energy storage space, within which multiple battery boxes 30 and multiple discharge seats 111 are arranged. The battery boxes 30 are mounted on the discharge seats 111 and power the transportation vehicle through the discharge seats 111. The movement range of the transport module 121 also includes the placement space of the rotating base 1222 on the set plane. The transport module 121 is used to move the battery boxes 30 between the energy storage space and the rotating seats 1221. The battery swapping station includes a swapping unit 20 and a charging base. The charging base can charge the battery boxes 30 to achieve their recycling and ensure that a sufficient number of battery boxes 30 with higher charge are available for replacement. The battery boxes 30 with higher charge are those with a charge level exceeding a preset value. The replacement unit 20 is used to move the battery box 30 into the charging base and rotating base 1221.

[0065] In some embodiments, the transport vehicle includes a handling module 121. The movement range of the handling module 121 and the space enclosed by the set plane include the energy storage space. 0 < G ≤ T × A, where A is the dimension of the battery box 30 along the second direction Q2, G is the distance between two adjacent rows of battery boxes 30, and 0 < T ≤ 1.1. 0 < T indicates that there is a distance between two adjacent rows of battery boxes 30, and T ≤ 1.1 restricts the distance between two adjacent rows of battery boxes 30 to be less than a certain value, that is, the distance between the battery boxes 30 on adjacent discharge seats 111 is relatively compact. This setting allows the battery boxes 30 in the energy storage space to be arranged more compactly, thereby achieving full utilization of the energy storage space. Storing more battery boxes 30 in the same volume of energy storage space effectively increases the energy density in the energy storage space. When T = 1.1, and there are battery boxes 30 on adjacent discharge seats 111, although the battery boxes 30 can be moved through the space between two adjacent rows of battery boxes 30, it is easy for the moved battery box 30 to collide with the battery boxes 30 on the discharge seat 111. Therefore, when both rows of discharge seats 111 have battery boxes 30, the battery boxes 30 cannot be moved through the space between the two adjacent rows of battery boxes 30.

[0066] 0 < D ≤ T × A, where D is the minimum distance between the battery box 30 and the edge of the energy storage space in the second direction Q2, and 0 < T ≤ 1.1. 0 < T indicates a gap between adjacent rows of battery boxes 30, and T ≤ 1.1 restricts the minimum distance between the battery box 30 and the edge of the energy storage space to a certain value, meaning the distance between the battery box 30 closest to the edge of the energy storage space and the energy storage space is relatively small. This arrangement demonstrates that the arrangement of multiple battery boxes 30 within the energy storage space fully utilizes the space between the battery box 30 and the edge of the energy storage space. This allows more battery boxes 30 to be stored within the same volume of energy storage space, effectively increasing the energy density in the energy storage space. When T = 1.1, although the battery box 30 can be moved using the minimum distance between it and the edge of the energy storage space, it is prone to collisions between the moved battery box 30 and adjacent battery boxes 30 or the edge of the energy storage space. Therefore, the space between the battery box 30 and the edge of the energy storage space cannot be used for movement.

[0067] 0 < F < T × C, where C is the dimension of the battery box 30 along the third direction (the height direction of the battery box 30), F is the minimum distance between the top of the battery box 30 and the top of the energy storage space along the third direction, and 0 < T ≤ 1.1. 0 < T indicates that there is a gap between the top of the battery box 30 and the top of the energy storage space. T ≤ 1.1 restricts the gap between the top of the battery box 30 and the top of the energy storage space to be less than a certain value, meaning the height dimension of the energy storage space is relatively compact. When T = 1.1, and there is a gap between the top of the battery box 30 and the top of the energy storage space, although the battery box 30 can be moved through the space between them, it is easy for the moved battery box 30 to collide with the battery box 30 on the discharge base 111. Therefore, the battery box 30 cannot be moved through the space between the top of the battery box 30 and the top of the energy storage space.

[0068] In some embodiments, 0 < E ≤ T × B. Here, E is the distance between the battery box 30 in the energy storage space and the battery box 30 on the rotating base 1221 along the first direction Q1, B is the dimension of the battery box 30 along the first direction Q1, and 0 < T ≤ 1.1. 0 < T indicates that there is a distance between the battery box 30 in the energy storage space and the battery box 30 on the rotating base 1221 along the first direction Q1. T ≤ 1.1 restricts the minimum distance between the battery box 30 and the edge of the energy storage space to be less than a certain value, meaning that the distance between the battery box 30 closest to the edge of the energy storage space and the energy storage space is small. This setting indicates that the arrangement of multiple battery boxes 30 within the energy storage space fully utilizes the space between the battery box 30 and the edge of the energy storage space. This allows more battery boxes 30 to be stored in the same volume of energy storage space, effectively increasing the energy density in the energy storage space. When T is 1.1, although the battery box 30 can be moved within the minimum distance between the edge of the energy storage space, it is easy for the moved battery box 30 to collide with adjacent battery boxes 30 or the edge of the energy storage space. Therefore, it is not possible to move the battery box 30 using the space between the edge of the energy storage space.

[0069] To address the aforementioned problems, this application provides a battery swapping method for transportation vehicles. Figure 6 A flowchart illustrating the steps of a battery swapping method for a transportation vehicle according to an embodiment of this application is shown, the battery swapping method including steps S10 to S40.

[0070] Step S10: When the transport vehicle arrives at the battery swapping area of ​​the battery swapping station, the first battery box 30 is moved to a rotating seat 1221, and the second battery box 30 is moved from the battery swapping station to another rotating seat 1221. The first battery box 30 is the battery box 30 in the first row of battery boxes 30 with a charge level lower than a preset value, and the second battery box 30 is the battery box 30 in the battery swapping station with a charge level higher than the preset value.

[0071] Step S20: Move the first battery box 30 to the battery swapping station.

[0072] Step S30: Move the third battery box 30 into the rotating seat 1221. The third battery box 30 is the battery box 30 in the second row of battery boxes 30 with a power level lower than a preset value. The third battery box 30 is located in the same column as the first battery box 30. The space swept by the third battery box 30 during the movement at least partially overlaps with the space where the first battery box 30 is placed on the transport vehicle.

[0073] Step S40: Move the second battery box 30 to the first preset position, wherein the first preset position is the placement position of the third battery box 30 in the energy storage space.

[0074] Figures 9-17This is a schematic diagram of each step in the battery swapping method according to an embodiment of this application. The battery swapping method according to an embodiment of this application will be described in detail below with reference to the accompanying drawings.

[0075] Symbol ① represents the first battery box 30, symbol ② represents the second battery box 30, and symbol ③ represents the third battery box 30.

[0076] Figure 8 This diagram illustrates the situation when a transport vehicle arrives at the battery swapping area of ​​a battery swapping station. The transport vehicle is equipped with multiple battery boxes 30 and two rotating bases 1221. The multiple battery boxes 30 supply power to the transport vehicle. The multiple battery boxes 30 are arranged in two rows and M columns within the energy storage space, where M is a positive integer ≥ 1. The column direction of the multiple battery boxes 30 is a first direction Q1, and the row direction is a second direction Q2. The multiple battery boxes 30 and the rotating bases 1221 are arranged sequentially along the first direction Q1, with the battery boxes 30 closer to the rotating bases 1221 forming the first row, and the battery boxes 30 further away from the rotating bases 1221 forming the second row.

[0077] In some embodiments, when powering the vehicle, multiple battery boxes 30 are powered sequentially in columns. That is, when the power levels of both battery boxes 30 in column M are lower than a preset value, the power is switched to the two battery boxes 30 in column M+1. Simultaneously, when the battery boxes 30 in column M are powered, the battery boxes 30 in the first row are powered first; when the power levels of the battery boxes 30 in the first row are lower than a preset value, the battery boxes 30 in the second row are powered.

[0078] Figure 9 A schematic diagram showing the positions of the first battery box 30 and the third battery box 30 in the first column is shown.

[0079] Figure 10 A schematic diagram is shown of moving the first battery box 30 into a rotating seat 1221. In some embodiments, when the transport vehicle arrives at the battery swapping area of ​​the battery swapping station, the status of multiple battery boxes 30 is acquired, including the power level of the multiple battery boxes 30. When the power level of at least one row of battery boxes 30 is lower than a preset value, battery swapping is performed using the above-described battery swapping method. When M≥2, the row in which the first battery box 30 and the third battery box 30 are located is determined based on the status of the multiple battery boxes 30. The first battery box 30 is then moved to the rotating seat 1221 closest to it.

[0080] Figure 11 A schematic diagram shows the movement of the second battery box 30 from the battery swapping station to another rotating base 1221. To improve battery swapping efficiency, Figure 10 The steps shown are the same as Figure 11 The steps shown can be performed simultaneously or sequentially. Figure 10 Perform the steps shown below again. Figure 11The steps shown. Alternatively, you can perform the following steps first. Figure 11 Perform the steps shown below again. Figure 10 The steps shown. Preferably, Figure 10 The steps shown are the same as Figure 11 The steps shown are performed simultaneously, which makes the battery swapping more efficient.

[0081] Figure 12 A schematic diagram is shown after the first battery box 30 has been moved to the battery swapping station. After the first battery box 30 has been moved to the battery swapping station, a second battery box 30 is mounted on one rotating seat 1221, while the other rotating seat 1221 is left empty, in preparation for the removal of the third battery box 30.

[0082] Figure 13 A schematic diagram is shown of moving the third battery box 30 into the rotating seat 1221. The third battery box 30 is the battery box 30 in the second row of battery boxes 30 with a power level lower than a preset value. The third battery box 30 is located in the same column as the first battery box 30. The space swept by the third battery box 30 during movement at least partially overlaps with the space where the first battery box 30 is placed on the transport vehicle. The third battery box 30 moves by utilizing the empty space left by the first battery box 30, avoiding collisions with adjacent battery boxes 30 during movement and improving the safety of battery swapping.

[0083] Figure 14 A schematic diagram is shown after the third battery box 30 has been moved to the battery swapping station. After the third battery box 30 has been moved to the battery swapping station, the second battery box 30 is mounted on one rotating base 1221, while the other rotating base 1221 is left empty.

[0084] Figure 15 This diagram illustrates the movement of the second battery box 30 to a first preset position. The first preset position is the placement position of the third battery box 30 within the energy storage space.

[0085] After moving the second battery box 30 to the first preset position, the method further includes moving another second battery box 30 from the battery swapping station to a rotating seat 1221, and moving the second battery box 30 to the second preset position.

[0086] Figure 16 A schematic diagram is shown of moving another second battery box 30 from the battery swapping station to a rotating base 1221.

[0087] Figure 17 This diagram illustrates the movement of the second battery box 30 to a second preset position. The second preset position is the placement position of the first battery box 30 within the energy storage space.

[0088] The battery swapping method provided in this application allows for the removal of the third battery box 30 after the first battery box 30 is removed, utilizing the space freed up by the removal of the first battery box 30. This avoids the first battery box 30 obstructing the removal of the third battery box 30. While fully utilizing the space of the energy storage unit 11 and ensuring the energy density of the energy storage space, it also enables the safe and reliable replacement of the second row of battery boxes 30, avoiding safety issues such as collisions and compression during the battery box 30 replacement process.

[0089] In some embodiments, the transport vehicle is further provided with a rotating base 1222, and two rotating seats 1221 are disposed on the rotating base 1222. The two rotating seats 1221 are symmetrically arranged about the rotation axis of the rotating base 1222. When the rotating seats 1221 are in the first state, the long side of the rotating seats 1221 is parallel to the first direction Q1.

[0090] Before step S20, the above method further includes step S50. Step S50: Rotate the base 1222 to exchange the positions of the two rotating seats 1221.

[0091] Following step S20, the above method further includes step S60. Step S60: Rotate the base 1222 to exchange the positions of the two rotating seats 1221.

[0092] Figure 18 It shows from Figure 11 A schematic diagram after step S50. Both the rotating base 1221 and the transport module 121 are located on the transport vehicle, and the movement distance between the battery box 30 gripped by the transport module 121 and the rotating base 1221 is relatively small. The replacement unit 20 is located in the battery swapping station, and the movement distance between the battery box 30 gripped by the replacement module 20 and the rotating base 1221 is larger than the movement distance between the transport module 121 and the rotating base 1221. For example, the battery swapping station is located in... Figure 18 The replacement unit 20 is also located on the right side of the rotating base 1222. Figure 18 The right side of the rotating base 1222. After the rotating base 1222 rotates, the first battery box 30 is moved to... Figure 18 On the right side, the second battery box 30 was moved to Figure 18 On the left side of the middle. By performing step S50, the positions of the two battery boxes on the rotating base 1222 are swapped, thereby reducing the travel distance when the replacement unit grabs the first battery box 30 and speeding up the battery replacement process.

[0093] Figure 19 A schematic diagram is shown after the first battery box 30 has been moved to the battery swapping station. After the first battery box 30 has been moved to the battery swapping station, a second battery box 30 is mounted on one rotating base 1221, while the other rotating base 1221 is left empty.

[0094] Figure 20 A schematic diagram is shown after step S60 is executed. The second battery box 30 is moved to the position using the rotating base 1222. Figure 20 The rotating base 1221 on the right side lays the foundation for the removal of the third battery box 30, and prevents the second battery box 30 from blocking the third battery box 30.

[0095] Before step S40, the method further includes step S70. Step S70: Rotate the base 1222 to exchange the positions of the two rotating seats 1221.

[0096] Figure 21 A schematic diagram is shown after step S70 is executed. Since the transport module 121 is a hoisting device, the rotating base 1222 is more stable than the transport module 121. If the second battery box 30 is located... Figure 21 When the transport module 121 is hoisted on the rotating seat 1221 on the right, it will carry the second battery box 30 through it. Figure 21 Moving the rotating seat 1221 on the left to the first preset position could easily cause the second battery box 30 to collide with other battery boxes 30 on the discharge seat 111 during the movement. Therefore, the position of the second battery box 30 is moved to the rotating seat 1221 in the same column as the first preset position, and then the second battery box 30 is moved to the first preset position through step S40, which shortens the moving distance of the transport module 121 and improves the stability of the movement of the second battery box 30.

[0097] By flexibly adjusting the positions of the two rotating seats 1221 using the rotating base 1222, the movement distance of the battery box during the battery swapping process is shortened, improving the battery swapping efficiency. Furthermore, since the rotating base 1222 is more stable than hoisting equipment such as the handling module 121 or the replacement unit 20, when the battery boxes 30 on the two rotating seats 1221 need to be swapped, the rotation of the rotating base 1222 completes the swapping of the battery boxes 30 on the rotating seats 1221. This not only increases the battery swapping speed but also improves the safety of the movement process, preventing collisions between the battery boxes during transport.

[0098] In execution Figure 13 In this process, the positions of the third battery box 30 and the second battery box 30 can be directly interchanged by rotating the base 1222, and then the second battery box 30 is moved into the first preset position of the first column. A new second battery box 30 is then moved onto the idle rotating seat 1221, and finally the new second battery box 30 is moved into the second preset position of the first column. The rotating base 1222 avoids obstruction of the path of the second battery box 30 to the first and second preset positions. Subsequently, the third battery box 30 can be stored on the rotating seat 1221 for later use, or it can be moved into the charging dock.

[0099] In some embodiments, when the power levels of both battery boxes 30 in the second column of the transport vehicle are lower than a preset value, the battery boxes 30 in the first column are replaced with the second battery boxes 30. Then, the first battery boxes 30 in the second column are moved to the nearest rotating seat 1221, and then a second battery box 30 is moved from the charging seat to another rotating seat 1221. The first battery box 30 on the rotating seat 1221 is moved into the charging seat, the third battery box 30 in the second column is moved into the rotating seat 1221, and then the third battery box 30 is moved into the charging seat. The second battery box 30 is moved to the first preset position in the second column, and then a new second battery box 30 is moved from the charging seat into the rotating seat 1221. Finally, the second battery box 30 on the rotating seat 1221 is moved to the second preset position in the second column.

[0100] In some embodiments, when the transport vehicle is equipped with multiple rows of battery boxes 30, such as four rows, the batteries are swapped sequentially for the first, second, third, and fourth rows. The first battery box 30 of the row requiring swapping is moved to a rotating seat 1221, and then the second battery box 30 of the charging seat is moved to another rotating seat 1221. The first battery box 30 on the rotating seat 1221 is moved to the charging seat, and then the third battery box 30 of the same row is moved to an empty rotating seat 1221, and then moved to the charging seat. A new second battery box 30 is removed from the charging seat and placed on an empty rotating seat 1221. At this point, both rotating seats 1221 have second battery boxes 30. One second battery box 30 is moved to an empty first preset position, and then the other second battery box 30 is moved to an empty second preset position. This completes the swapping of one row of battery boxes 30. If there are multiple rows, the swapping is performed sequentially using the same method to ensure the orderly swapping of the battery boxes 30.

[0101] In some embodiments, such as Figure 3 , Figure 7 As shown, when the rotating base 1221 is in the first state, in the first direction Q1, one of the rotating bases 1221 at least partially overlaps with the projection of the m-th column battery box 30, and the other rotating base 1221 at least partially overlaps with the projection of the (m+1)-th column battery box 30. The m-th and (m+1)-th columns are adjacent columns, 1 ≤ m < M. This allows the transport module 121 to move only along the first direction Q1 and the second direction Q2, thereby reducing the positioning accuracy of the transport unit. When the transport module 121 moves the (m+2)-th column battery box 30, it moves into the rotating base 1221 after passing through the reference area 40. The reference area 40 is the area on the side of one rotating base 1221 away from the other rotating base 1221.

[0102] In some embodiments, such as Figure 8As shown, when the rotating base 1221 is in the first state, in the first direction Q1, one of the rotating bases 1221 at least partially overlaps with the projection of the m-th column battery box 30, and the other rotating base 1221 at least partially overlaps with the projection of the (m+2)-th column battery box 30. The m+1-th column is spaced between the m-th and (m+2)-th columns, where 1 ≤ m < M-1. By having the two rotating bases 1221 overlap with the projections of the battery boxes 30, the positioning accuracy of the handling module 121 is improved, enhancing the smoothness of the overall battery swapping process. When the first battery box 30 of the (m+1)-th column is moved into the rotating base 1221, both rotating bases 1221 can be selected for placement. The first battery box 30 is preferentially placed in the rotating base 1221 closest to the replacement unit 20, thus facilitating the replacement unit 20 to place the first battery box 30 into the charging base and improving the overall battery swapping efficiency.

[0103] Implementation 2:

[0104] In this embodiment, this application provides a battery swapping system for a transportation vehicle, which is applied to the aforementioned battery swapping method for the transportation vehicle. The battery swapping system for the transportation vehicle includes multiple battery boxes 30, battery swapping units 12, and battery swapping stations.

[0105] Multiple battery packs 30 provide power to the transportation vehicle, ensuring its range.

[0106] The battery swapping unit 12 includes a transport module 121, a rotating base 1222, and two rotating seats 1221. The transport module 121 is set on a designated plane to ensure the stability and accuracy of its movement trajectory. The space enclosed by the transport module 121 and the designated plane includes a power storage space, within which multiple battery boxes 30 are installed, allowing for centralized and orderly storage of the battery boxes 30 and avoiding space waste.

[0107] The rotating base 1222 rotates to change the position of the two rotating seats 1221, thus exchanging the positions of the battery boxes 30 on the rotating seats 1221 to adapt to the battery swapping requirements in the battery swapping method. When the two rotating seats 1221 are arranged sequentially along the second direction Q2, the length direction of the battery boxes 30 in the energy storage space is parallel to the length direction of the battery boxes 30 on the rotating seats 1221. This allows the transport module 121 to move the battery boxes 30 between the energy storage space and the rotating seats 1221 without having to adjust the orientation of the battery boxes 30, thereby reducing transport operation steps and improving the transfer efficiency of the battery boxes 30.

[0108] The battery swapping station includes a swapping unit 20 and a charging base. The charging base is used to charge the battery boxes 30 inside, replenishing their power in a timely manner and ensuring a continuous supply of battery boxes 30. The swapping unit 20 is used to move the battery boxes 30 into and out of the charging base and rotating base 1221, enabling the orderly flow of battery boxes 30 between them. This ensures that charged battery boxes 30 can be delivered to the swapping stage in a timely manner, and that battery boxes 30 with less than a set power level can be promptly charged in the charging base. The maximum number of battery boxes 30 that the energy storage space can hold, plus the number of charging bases, equals the sum of the number of battery boxes 30 on the transport vehicle and the number of battery boxes 30 in the swapping station. This avoids waste due to excess battery boxes 30 or delays caused by insufficient battery boxes 30.

[0109] Example 3:

[0110] In this embodiment, this application provides a transportation vehicle, which is applicable to the battery swapping method described above. For example... Figure 1 As shown, the transportation vehicle includes a battery box 30, an energy storage component 10, and a transport body 13.

[0111] The moving range of the transport body 13 and the handling module 121 forms a power storage space, facilitating the storage of the battery box 30. The transport body 13 is connected to the handling module 121; the discharge base 111 is connected to the transport body 13; the transport body 13 provides an installation base for the battery base, and the battery box 30 can provide power to the transport body 13 through the discharge base 111. The transport body 13 can be a vehicle, ship, aircraft, etc. The rotating base 1222 is rotatably connected to the power storage space of the transport body 13, enabling the rotating base 1222 to drive the rotating base 1221 to move.

[0112] In other embodiments, such as Figure 2 As shown, the handling module 121 includes a large trolley guide rail 1211, a small trolley guide rail 1212, a small trolley body 1213, and a lifting unit 1214. The small trolley guide rail 1212 moves along a first direction Q1 on the large trolley guide rail 1211; the small trolley body 1213 moves along a second direction Q2 on the small trolley guide rail 1212, and the small trolley body 1213 drives the lifting unit 1214 to move along a third direction. The moving area of ​​the small trolley body 1213 and the set plane enclose a power storage space; the lifting unit 1214 is used to grab the battery box 30 in the power storage space. When the energy storage component 10 needs to be swapped, the trolley guide rail 1212 moves on the main trolley guide rail 1211, and the trolley body 1213 moves on the trolley guide rail 1212, thereby realizing the ability of the trolley body 1213 to move in multiple directions. Then, the trolley body 1213 drives the hoisting part 1214 to grab and fix the battery box 30, thereby realizing the movement of the battery box 30 in the energy storage space.

[0113] like Figure 4 As shown, the replacement unit 20 includes a fixed base 21, a cantilever 22, and a gripping part 23. One end of the cantilever 22 is connected to the fixed base 21, and the other end is connected to the gripping part 23. When the battery holder on the rotating module 122 is removed, the gripping part 23 is used to install the battery box 30 onto the battery holder on the rotating module, or to remove the battery box 30 from the battery holder on the rotating module, thereby performing a battery swapping operation on the energy storage component 10.

[0114] The energy storage unit 11 also includes a compartment 112, which forms an enclosing space with the set plane, and the discharge base 111 and the battery box 30 are located within the enclosing space. The compartment 112 can prevent the discharge base 111 and the battery box 30 from being affected by external environmental factors.

[0115] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
