Description

Technical Field

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

[0002] In the current field of battery swapping technology, the deployment of battery swapping stations is crucial. Currently, battery swapping stations typically require a certain amount of space to complete vehicle battery swapping operations. These stations primarily consist of a battery storage area, vehicle access lanes, and a battery swapping operation area. The battery storage area is used to store spare batteries and provides a foundation for battery swapping. The vehicle access lanes ensure smooth entry and exit of vehicles at the battery swapping station, ensuring the continuity of the battery swapping process. The battery swapping operation area is where the actual battery swapping takes place.

[0003] However, when battery swap stations are deployed in locations with limited available space, the spatial layout of their various components is severely restricted, often preventing them from operating normally. This is primarily because each functional area of a battery swap station requires a reasonable amount of space to ensure proper operation. For example, insufficient height in the battery swap area may prevent normal battery swapping operations, rendering the battery swap equipment inoperable. Summary of the Invention

Through this series of steps, under the space conditions where the width of the battery-swapping area is greater than or equal to the width of the battery box and less than twice the width of the battery box, and the width and height of the battery-swapping station are limited, it is possible to complete the battery-swapping operation of the vehicle in a relatively small battery-swapping station by utilizing the transfer of the rotating seat, thereby solving the problem of how to achieve battery-swapping under the limited width and height of the battery-swapping station.

[0088] In this embodiment, the spatial layout of the battery swap station has a significant impact on the implementation of the battery swap operation. Currently, battery swap stations are limited in width and height. Under such space constraints, the hoisting unit 11 is easily restricted when grabbing the low-charge battery box 02 and subsequently moving the battery box 02 to the charging station, making the operation difficult to carry out smoothly. Therefore, in order to solve the above problems, the present invention provides a vehicle battery swap method.

[0089] The battery swap system can be applied to vehicle battery swap methods, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the battery exchange system may include a battery exchange component 01, a battery box 02, and a battery exchange vehicle 03. The battery exchange component 01 may include a hoisting unit 11, a rotating unit 12, four battery seat units 13, a battery exchange area, and a control unit 15. The area projected downward from the moving range of the hoisting unit 11 includes a set area, and the battery seat unit 13, the rotating unit 12, and the battery exchange area may be sequentially arranged in the set area along a first direction. The first direction may be the length direction of the battery seat unit 13, that is, Figure 2 The four battery holder units 13 can be divided into two columns along the first direction and two rows along the second direction. The second direction can be the width direction of the battery holder unit 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. During the battery swapping process of the battery swapping vehicle 03, the rotating base 121 rotates around the central axis of the rotating base 121, and the rotating seat 122 is connected to the top of the rotating base 121. After grabbing the low-power battery box 02 on the battery swapping vehicle 03 and moving it to the rotating seat 122, the rotating seat 122 can be allowed to rotate smoothly to prevent the battery box 02 on the rotating seat 122 from falling. At the same time, when there are battery boxes 02 on both rotating seats 122, the interval between the two rotating seats 122 can prevent the lifting unit 11 from moving the battery box 02 on the rotating seat 122 and causing damage to the battery box 02. The width of the battery swapping area is greater than or equal to the width of the battery box 02 and less than twice the width of the battery box 02. The distance between the symmetry plane of the battery swapping area in the second direction and the symmetry plane of any row of battery seat units 13 in the second direction along the second direction is less than a set value, and the set value can be 10cm to 20cm. The control unit 15 can be connected to the lifting unit 11. The control unit 15 can obtain whether the battery box 02 on the battery swap vehicle 03 has entered the battery swap area. At the same time, the control unit 15 can also obtain the direction of the battery box 02, so as to facilitate the lifting unit 11 to replace the battery box 02 on the battery swap vehicle 03.

[0090] A can be the distance between the hanging unit 11 and the battery seat unit 13 along the third direction, and the third direction can be the height direction of the battery box 02, that is, Figure 3In the up and down directions shown, B can be the height of the battery box 02, B<A<2*B, wherein B<A can ensure that there is enough space for the hoisting unit 11 to disassemble and install the battery box 02 and the battery seat unit 13 in the third direction, and A<2*B can avoid the redundancy of the height space when the hoisting unit 11 moves along the third direction. C can be the distance between the battery swap area and any rotating seat 122 along the first direction, and L can be the length of the battery box 02. 0≤C<T*L, 1≤T≤1.1, which can reduce the movement path of the hoisting unit 11 along the first direction, thereby reducing the size of the hoisting unit along the first direction. D can be the minimum spacing between the first row of battery holder units 13 and the set area along the second direction. E can be the minimum spacing between the second row of battery holder units 13 and the set area along the second direction. K can be the width of the battery box 02. 0≤D<T*K, 0≤E<T*K. Limiting the spacing between the first and second rows of battery holder units 13 and the set area along the second direction can reduce the path of movement of the hanging unit 11 along the second direction, thereby reducing the size of the hanging unit along the second direction. F can be the minimum spacing between the first and second rows of battery holder units 13. 0≤F<T*K. Minimizing the spacing between the first and second rows of battery holder units 13, 13, further reduces the path of movement of the hanging unit 11 along the second direction.

[0091] The four battery boxes 02 can be detachably connected to any four of the battery holder units 13 and the rotating seat 122. The battery swap vehicle 03 may include a vehicle body 31 and a mounting seat 32. The vehicle body 31 can be detachably and electrically connected to the mounting seat 32, and the battery box 02 can be detachably and electrically connected to the mounting seat 32. The vehicle body 31 can obtain electrical energy from the battery box 02 through the mounting seat 32, thereby driving the battery swap vehicle 03 to travel normally on the road.

[0092] like Figure 1 As shown, the present invention provides a vehicle battery replacement method, which may include steps S10 to S40. Steps S10 to S40 of the vehicle battery replacement method will be described in detail below.

[0093] Step S10, based on the battery swap vehicle 03 driving towards the battery swap area, obtain the status data of the vehicle battery swap system. By obtaining real-time data on the direction and power of the battery box 02, the hoisting unit 11 can implement different battery swap plans based on the status data, thereby improving the battery swap efficiency. Among them, the status data of the vehicle battery swap system may include the direction of the low-power battery box 02 on the battery swap vehicle 03, the power of the battery box 02 in the battery holder unit 13, the four battery holder units 13 are divided into two columns along the first direction and two rows along the second direction, the width of the battery swap area is greater than or equal to the width of the battery box 02 and less than twice the width of the battery box 02, and the distance between the symmetry plane of the battery swap area in the second direction and the symmetry plane of any row of battery holder units 13 in the second direction is less than a set value along the second direction, and the set value can be 10cm to 20cm.

[0094] In step S20, based on the fact that the state data is in the first state and the low-charged battery box 02 on the battery-swapping vehicle 03 is located in the battery-swapping area, and the projection area of the low-charged battery box 02 toward the battery-swapping area is located in the battery-swapping area, the hoisting unit 11 grabs the low-charged battery box 02 on the battery-swapping vehicle 03. The first state includes that the power levels of the battery boxes 02 in the four battery holder units 13 are all greater than or equal to a first set power level. The first set power level can be a fixed value, such as 80% or 90% of the ratio of the total power level of the battery box 02 to the current power level of the battery box 02, or it can be a variable value. The direction of the low-charged battery box 02 on the battery-swapping vehicle 03 is the same as the direction of the battery box 02 on the first row of battery holder units 13, and the battery holder unit 13 close to the battery-swapping area is the first row of battery holder units 13. By using the power levels of the battery boxes 02 in the four battery holder units 13, it is ensured that the hoisting unit 11 only grabs the battery boxes 02 with a power level greater than or equal to the first set power level, thereby providing sufficient driving range for the battery-swapping vehicle 03.

[0095] In step S30, based on the hoisting unit 11 grabbing the low-power battery box 02 on the battery-swapping vehicle 03, 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 of the rotating unit 12. By moving the low-power battery box 02 to the second row of rotating seats 122, it can pave the way for subsequent steps. At the same time, by rotating the rotating base 121 around the central axis of the rotating base 121, the direction of the battery box 02 is changed, thereby realizing the battery-swapping action when the moving range of the hoisting unit 11 is limited.

[0096] In step S40, 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, and the hoisting unit 11 moves the battery box 02 in the first row and second column of battery holder units 13 to a detachable connection with the mounting seat 32 of the battery-swapping vehicle 03. Among them, the battery holder unit 13 close to the battery-swapping area is the second column of battery holder units 13. Because the first row and second column of battery holder units 13 are closer to the battery-swapping area, combined with the transit storage function of the rotating seat 122, the direction and position of the battery box 02 are adjusted, thereby realizing the battery-swapping action when the moving range of the hoisting unit 11 is limited.

[0097] In this embodiment, step S20 may include steps S21 and S22 , and steps S21 and S22 will be described in detail below.

[0098] Step S21, based on the status data being in the first state, the hoisting unit 11 can be moved above the battery exchange area.

[0099] In step S22, based on the low-power battery box 02 on the battery-swapping vehicle 03 arriving at the battery-swapping area and the hoisting unit 11 moving above the battery-swapping area, the hoisting unit 11 grabs the low-power battery box 02 of the battery-swapping vehicle 03. In this way, when the low-power battery box 02 on the battery-swapping vehicle 03 arrives at the battery-swapping area, the hoisting unit 11 can directly move down to grab the low-power battery box 02 of the battery-swapping vehicle 03, thereby reducing the battery-swapping time and improving the battery-swapping efficiency.

[0100] In this embodiment, the vehicle battery replacement method may further include step S21, which may include steps S211 to S215, which are described in detail below. Step S211 is performed after step S10 is completed.

[0101] In step S211, based on the state data being in the second state and the battery box 02 with low power on the battery swap vehicle 03 being located in the battery swap area, the hoisting unit 11 moves the battery box 02 on the second row, second column of the battery holder unit 13 to the first row of rotating seats 122. The second state may include that the power of the battery box 02 in the second row, second column is greater than or equal to the second set power, the power of the first row, first row of the battery holder unit 13, the second row, first row of the battery holder unit 13, and the first row, second row of the battery holder unit 13 is respectively less than the power of the battery box 02 in the second row, second row of the battery holder unit 13, the second set power may be the same as the first set power, the direction of the battery box 02 with low power on the battery swap vehicle 03 is opposite to the direction of the battery box 02 on the first row of the battery holder unit 13, the direction of the battery box 02 with low power on the battery swap vehicle 03 is the same as the direction of the battery box 02 on the second row of the battery holder unit 13, and the direction of the battery box 02 on the first row of the battery holder unit 13 after rotating 180° around the height direction of the battery box 02 is the same as the direction of the battery box 02 on the second row of the battery holder unit 13. Since the low-power battery box 02 on the battery-swapping vehicle 03 is in the opposite direction to the battery box 02 on the first row of battery seat units 13, the rotating seat 122 can be used as a direction conversion platform to solve the problem that the battery box 02 in the battery seat unit 13 cannot be installed on the mounting seat 32 on the battery-swapping vehicle 03 due to inconsistent directions of the battery box 02.

[0102] Step S212, based on the lifting unit 11, the battery box 02 on the second row and second column of the battery seat unit 13 is moved to the first row of rotating seats 122, and the rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121. Through the 180° rotation of the rotating base 121, space is reserved for the low-power battery box 02 on the battery exchange vehicle 03 to avoid conflicts between the battery boxes 02 and affect the battery exchange efficiency. After the rotating base 121 rotates 180°, the first row of rotating seats 122 and the first row of battery seat units 13 are located in the same row.

[0103] Step S213, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, the low-power battery box 02 of the battery-swapping vehicle 03 is moved to the first row of rotating seats 122 through the lifting unit 11, so that the mounting seat 32 on the battery-swapping vehicle 03 is in an idle state, thereby facilitating the battery box 02 on the battery seat unit 13 to be moved to the mounting seat 32 on the battery-swapping vehicle 03. The idle state may be that there is no battery box 02 on the mounting seat 32.

[0104] In step S214, based on the lifting unit 11, the low-power battery box 02 of the battery-swap 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 with a power greater than or equal to the second set power on the rotating base 122 is in the same direction as the mounting seat 32 on the battery-swap vehicle 03.

[0105] In step S215, 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.

[0106] In this embodiment, the vehicle battery replacement method may further include step S22, which may include steps S221 to S225. Steps S221 to S225 are described in detail below. Step S22 is performed after step S10 is completed.

[0107] Step S221, when the battery box 02 of the battery-swapping vehicle 03 has not entered the battery-swapping area, based on the status data being in the second state, the second state can be judged by the driving direction of the battery-swapping vehicle 03, the lifting unit 11 moves the battery box 02 on the second row and second column of the battery seat unit 13 to the first row of rotating seats 122, preparing in advance for the subsequent battery-swapping steps. At the same time, the battery box 02 on the battery-swapping vehicle 03 has a shorter waiting time after arriving at the battery-swapping area, thereby improving the overall battery-swapping efficiency. Among them, the second state includes that the power of the battery boxes 02 in the four battery holder units 13 is greater than or equal to the second set power, the second set power can be the same as the first set power, the direction of the low-power battery box 02 on the battery swap vehicle 03 is opposite to the direction of the battery box 02 on the first row of battery holder units 13, the direction of the low-power battery box 02 on the battery swap vehicle 03 is the same as the direction of the battery box 02 on the second row of battery holder units 13, and the direction of the battery box 02 on the first row of battery holder units 13 after rotating 180° around the height direction of the battery box 02 is the same as the direction of the battery box 02 on the second row of battery holder units 13. Since the low-power battery box 02 on the battery swap vehicle 03 is in opposite directions to the battery box 02 on the first row of battery holder units 13, the rotating seat 122 can be used as a direction conversion platform to solve the problem that the battery box 02 in the battery holder unit 13 cannot be installed on the mounting seat 32 on the battery swap vehicle 03 due to inconsistent directions of the battery box 02.

[0108] In step S222, based on the lifting unit 11, the battery box 02 on the second row and second column of the battery seat unit 13 is moved to the first row of rotating seats 122. The rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121. The 180° rotation of the rotating base 121 makes the rotating seat 122 in the first row idle, thereby reserving space for the low-power battery box 02 on the battery-exchange vehicle 03, avoiding conflicts between the battery boxes 02 and affecting the battery-exchange efficiency.

[0109] Step S223, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121 and the low-power battery box 02 on the battery-swap vehicle 03 being located in the battery-swap area, the lifting unit 11 moves the low-power battery box 02 to the first row of rotating seats 122, so that the mounting seat 32 on the battery-swap vehicle 03 is in an idle state, thereby facilitating the battery box 02 on the battery seat unit 13 to be moved to the mounting seat 32 on the battery-swap vehicle 03.

[0110] In step S224, based on the lifting unit 11, the low-power battery box 02 of the battery-swap 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 with a power greater than or equal to the second set power on the rotating base 122 is in the same direction as the mounting seat 32 on the battery-swap vehicle 03.

[0111] In step S225, based on the rotation of the rotating base 121 by 180° around the central axis of the rotating base 121, the hoisting unit 11 moves the battery box 02 on the first row of rotating seats 122 to a position where it is detachably connected and electrically connected to the mounting seat 32, thereby completing the battery swapping operation for the battery swapping vehicle 03. In this way, by moving the battery boxes 02 in the battery seat unit 13 with a charge greater than or equal to the second set charge to the first row of rotating seats 122 in advance, when the battery box 02 with low charge on the battery swapping vehicle 03 is located in the battery swapping area, the overall time of the battery swapping step can be shortened, thereby improving the battery swapping efficiency of the battery swapping vehicle 03.

[0112] In this embodiment, the vehicle battery replacement method may further include step S23, which may include steps S231 to S2391. Steps S231 to S2391 are described in detail below. Step S23 is executed after step S10 is completed.

[0113] In step S231, based on the fact that the status data is in the third state and the low-charge battery box 02 on the battery swap vehicle 03 is located in the battery swap area, the hoisting unit 11 moves the battery box 02 on the first row and second column of the battery holder units 13 to the first row of rotating seats 122. The third state includes that the power of the battery box 02 on the first column of the battery holder units 13 is greater than or equal to the third set power, the third set power may be the same as the first set power, the power of the low-charge battery box 02 of the battery swap vehicle 03 on the second column of the battery holder units 13 is less than the third set power, the direction of the low-charge battery box 02 on the battery swap vehicle 03 in the battery swap area is opposite to the direction of the battery box 02 on the first row of the battery holder units 13, the direction of the low-charge battery box 02 on the battery swap vehicle 03 is the same as the direction of the battery box 02 on the second row of the battery holder units 13, and the direction of the battery box 02 on the first row of the battery holder units 13 after rotating 180° around the height direction of the battery box 02 is the same as the direction of the battery box 02 on the second row of the battery holder units 13. By determining the battery pack 02 on the battery holder unit 13 with a power level greater than or equal to the third set power level, the battery pack 02 with the higher power level is preferentially selected for battery replacement. At the same time, the battery pack 02 on the first row and first column of the battery holder unit 13 is preferentially selected for battery replacement, which shortens the battery replacement path and improves the efficiency of battery replacement.

[0114] In step S232, the battery boxes 02 on the first row, second column of the battery holder units 13 are moved onto the first row of rotating seats 122 using the hoisting unit 11. The rotating base 121 of the rotating unit 12 is rotated 180° about its central axis. This leaves room for the first row of rotating seats 122, and there are no battery boxes 02 on the first row, second column of the charging holder units. This allows for the movement of the first row, first column of battery boxes 02 with a charge level greater than or equal to the third set value, thereby facilitating the completion of subsequent steps.

[0115] Step S233, 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 and first column of battery seat units 13 to the first row of rotating seats 122, that is, the battery box 02 with a power greater than or equal to the third set power is moved to the first row of rotating seats 122.

[0116] Step S234, based on the lifting unit 11, the battery box 02 on the first row and first column of the battery seat unit 13 is moved to the first row of the rotating seat 122, and the rotating base 121 is rotated 180° around the central axis of the rotating base 121, so that the direction of the battery box 02 with a power less than the third set power is the same as the direction of the charging seat in the first row.

[0117] 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 the first row and first column of battery seat units 13, that is, the battery box 02 with a power less than the third set power is moved to the charging seat unit away from the battery replacement vehicle 03.

[0118] In step S236 , the hoisting unit 11 moves the battery box 02 on the first row of rotating seats 122 to the first row and first column of battery seat units 13 , and the hoisting unit 11 moves the battery box 02 on the second row of rotating seats 122 to the first row of rotating seats 122 .

[0119] Step S237, based on the lifting unit 11, the battery box 02 on the second row of rotating seats 122 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, reserving space on the first row of rotating seats 122, and reserving a channel in advance for the movement of the low-power battery box 02 of the battery-swapping vehicle 03.

[0120] Step S238, 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 to the first row of rotating seats 122.

[0121] Step S239, 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 with a power greater than the third set power is located in the first row of rotating seats 122, and the direction of the battery box 02 with a power greater than the third set power is the same as the direction of the mounting seat 32.

[0122] Step S2391, 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 be detachably connected and electrically connected to the mounting seat 32, thereby completing the battery replacement action of the battery replacement vehicle 03.

[0123] In this embodiment, the vehicle battery replacement method may further include step S24, which may include steps S241 to S2492. Steps S241 to S2492 are described in detail below. Step S24 is performed after step S10 is completed.

[0124] Step S241, based on the status data being in the fourth state and the low-power battery box 02 on the battery-swapping vehicle 03 being located in the battery-swapping area, the hoisting unit 11 moves the second row and second column of battery boxes 02 to the second row of rotating seats 122. Among them, the fourth state includes that the direction of the low-power battery box 02 on the battery swapping vehicle 03 in the battery swapping area is opposite to the direction of the battery box 02 on the first row of battery seat units 13, the direction of the low-power battery box 02 on the battery swapping vehicle 03 is the same as the direction of the battery box 02 on the second row of battery seat units 13, the direction of the battery box 02 on the first row of battery seat units 13 after rotating 180° around the height direction of the battery box 02 is the same as the direction of the battery box 02 on the second row of battery seat units 13, the power of the battery box 02 in the first column and second row of battery seat units 13 is greater than or equal to the fourth set power, the fourth set power can be the same as the first set power, the power of the first row of battery seat units 13 in the first column, the first row of battery seat units 13 in the second column, and the second row of battery seat units 13 in the second column are respectively less than the power of the battery box 02 in the first column and second row of battery seat units 13. By judging that the battery box 02 on the battery seat unit 13 has a power greater than or equal to the fourth set power, the battery box 02 with a higher power is selected first to perform the battery swap operation.

[0125] In step S242, the second row, second column battery box 02 is moved to the second row rotating seat 122 based on the hoisting unit 11, and the rotating base 121 of the rotating unit 12 is rotated 180° around the central axis of the rotating base 121. Space is reserved on the second row rotating seat 122 to establish a movable space channel for the high-power battery box 02 on the second row, first column battery holder unit 13. In step S243, based on the rotating base 121 being rotated 180° around the central axis of the rotating base 121, the hoisting unit 11 moves the battery box 02 on the second row, first column battery holder unit 13 to the second row rotating seat 122, reserving space for the low-power battery box 02 on the first row rotating seat 122 to facilitate the movement of the battery box 02.

[0126] Step S244, based on the lifting unit 11, the battery box 02 on the first row and first column of the battery seat unit 13 is moved to the second row of the rotating seat 122, and the rotating base 121 is rotated 180° around the central axis of the rotating base 121, so that the direction of the low-power battery box 02 on the second row of the rotating seat 122 is the same as the direction of the charging seat unit in the second row.

[0127] In step S245, based on the rotation of the rotating base 121 by 180 degrees around the central axis of the rotating base 121, the hoisting unit 11 moves the battery box 02 on the second row of rotating seats 122 to the second row first column of battery seat units 13. The battery box 02 with less power is placed in the first column. When a battery swap vehicle 03 needs to be swapped, the battery box 02 in the second column, which is easier to move, can be connected to the mounting base 32 first, thereby improving the battery swap efficiency.

[0128] Step S246 , using the hoisting unit 11 , the battery box 02 on the second row of rotating seats 122 is moved to the second row and first column of battery seat units 13 , and the rotating base 121 is rotated 180° around the central axis of the rotating base 121 .

[0129] In step S247 , 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 on the second row of rotating seats 122 to the first row of rotating seats 122 .

[0130] Step S248, based on the lifting unit 11, the battery box 02 on the second row of rotating seats 122 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 to reserve space for the low-power battery box 02 on the battery-swapping vehicle 03.

[0131] In step S249, the lifting unit 11 moves the low-power battery box 02 on the battery-swapping vehicle 03 to the first row of rotating seats 122 based on the rotating base 121 rotating 180 degrees around the central axis of the rotating base 121. The disassembly of the low-power battery box 02 on the battery-swapping vehicle 03 is completed.

[0132] In step S2491, the battery box 02 with low power on the battery-swapping vehicle 03 is moved to the first row of rotating seats 122 using the hoisting unit 11, and the rotating base 121 is rotated 180° around the central axis of the rotating base 121. This ensures that the battery box 02 with a power level greater than or equal to the fourth set power level is located on the first row of rotating seats 122, and the direction of the battery box 02 with a power level greater than or equal to the fourth set power level is the same as the direction of the mounting base 32.

[0133] Step S2492, 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.

[0134] In this embodiment, the vehicle battery replacement method may further include step S25, which may include steps S251 to S259, which are described in detail below. Step S25 is executed after step S10 is completed.

[0135] Step S251, based on the state data being the fifth state and the low-power battery box 02 on the battery-swapping vehicle 03 being located in the battery-swapping area, the hoisting unit 11 moves the battery box 02 on the second row, second column battery holder unit 13 to the second row rotating seat 122. The fifth state includes the power of the battery box 02 in the first row, second row battery holder unit 13 being greater than or equal to the fifth set power, the power of the first row, first row battery holder unit 13, the second row, first row battery holder unit 13, and the second row, second row battery holder unit 13 being less than the power of the battery box 02 in the first row, second row battery holder unit 13, respectively, the fifth set power may be the same as the first set power, the direction of the low-power battery box 02 on the battery-swapping vehicle 03 is the same as the direction of the battery box 02 on the first row battery holder unit 13, and by judging that the battery box 02 on the battery holder unit 13 has a power greater than or equal to the fifth set power, the battery box 02 with a higher power is preferentially selected for the battery-swapping operation.

[0136] In step S252, the battery box 02 on the second row, second column of the battery holder unit 13 is moved onto the second row of the rotating base 122 using the hoisting unit 11. The rotating base 121 of the rotating unit 12 is rotated 180° about its central axis. This leaves space on the second row of the rotating base 122, creating a movable passage for the battery box 02 with a capacity greater than or equal to the fifth set value.

[0137] Step S253 , 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 on the second row and first column battery seat units 13 to the second row rotating seat 122 .

[0138] Step S254, based on the lifting unit 11, the battery box 02 on the second row and first column battery seat unit 13 is moved to the second row rotating seat 122, and the rotating base 121 is rotated 180° around the central axis of the rotating base 121, so that the battery box 02 with a power less than the fifth set power on the second row rotating seat 122 is moved to the second row and first column battery seat unit 13 to establish a movable space channel.

[0139] Step S255 , 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 on the second row of rotating seats 122 to the second row and first column of battery seat units 13 .

[0140] Step S256, based on the lifting unit 11, the battery box 02 on the second row of rotating seats 122 is moved to the second row and first column of battery seat units 13, and the rotating base 121 is rotated 180° around the central axis of the rotating base 121 to establish a movable space channel for moving the low-power battery box 02 on the battery-exchange vehicle 03 to the first row of rotating seats 122.

[0141] Step S257, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, 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.

[0142] Step S258, 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. The battery box 02 with a power greater than or equal to the fifth set power is moved to the first row of rotating seats 122. At the same time, the direction of the battery box 02 on the first row of rotating seats 122 is the same as the direction of the mounting seat 32, preparing for battery replacement of the battery-swapping vehicle 03.

[0143] Step S259 , 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 on the first row of rotating seats 122 to be detachably connected and electrically connected to the mounting seat 32 .

[0144] In this embodiment, the battery swap system status data may further include the number of battery swap vehicles 03 in the waiting area. The waiting area is arranged on any side of the battery swap area along the second direction.

[0145] The vehicle battery replacement method may further include step S26, which may include steps S261 to S268, which are described in detail below. Step S26 is performed after step S40 is completed.

[0146] Step S261: Based on the hoisting unit 11, the battery box 02 in the first row and second column battery seat unit 13 is moved to a detachable connection with the mounting seat 32 of the battery swap vehicle 14 to obtain the status data of the vehicle battery swap system.

[0147] In step S262, based on the state data being in the sixth state, the hoisting unit 11 moves the battery box 02 in the battery holder unit 13 with a power level less than the sixth set power level to the rotating seat 122 in the same row as the battery box 02 with a power level less than the sixth set power level. The sixth state may include the battery box 02 on the first row of battery holder units 13 having a power level greater than or equal to the sixth set power level, the sixth set power level may be the same as the first set power level, the battery box 02 on the first row of battery holder units 13 in the second row having a power level greater than or equal to the sixth set power level, the battery box 02 on the second row of battery holder units 13 in the second row having a power level less than the sixth set power level, there being no battery swapping vehicles 03 in the waiting area, and the idle time of the battery swapping area being greater than a set time, which may be 1 minute. When there is no battery swapping vehicle 03 for battery swapping, the battery box 02 with a power level greater than or equal to the sixth set power level may be moved to the charging seat in the second row, and the battery box 02 with a power level less than the sixth set power level may be moved to the first row. This may shorten the overall battery swapping time when the battery swapping vehicle 03 enters the battery swapping area, thereby improving the battery swapping efficiency. The waiting area can be used to accommodate battery swapping vehicles waiting for battery swapping. When there are no battery swapping vehicles in the battery swapping area, the battery swapping vehicles in the waiting area can enter the battery swapping area in turn to complete the battery swapping.

[0148] In step S263, based on the lifting unit 11, the battery box 02 with a power less than the sixth set power in the battery seat unit 13 is moved to the rotating seat 122 in the same row as the battery box 02 with a power less than the sixth set power, and the rotating base 121 of the rotating unit 12 is rotated 180° around the central axis of the rotating base 121.

[0149] In step S264, 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 column and in the same row as the idle battery seat unit 13 to the idle rotating seat 122, thereby adjusting the positions of the battery box 02 with a power less than the sixth set power and the battery box 02 with a power greater than or equal to the sixth set power.

[0150] In step S265 , the hoisting unit 11 moves the battery box 02 in the first column and in the same row as the idle battery seat unit 13 to the idle rotating seat 122 , and the rotating base 121 rotates 180° around the central axis of the rotating base 121 .

[0151] Step S266 , 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 on the rotating seat 122 with a power less than the sixth set power to the first column and an empty row of battery seat units 13 .

[0152] Step S267, based on moving the battery box 02 with a power less than the sixth set power on the rotating seat 122 to the first column and an empty row of battery seat units 13, the rotating base 121 is rotated 180° around the central axis of the rotating base 121, so that the direction of the battery box 02 with a power greater than or equal to the sixth set power is the same as the direction of the empty battery seat unit 13.

[0153] Step S268, 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 second row of rotating seats 122 to the second and idle row of battery seat units 13, thereby moving the battery box 02 with a power less than the sixth set power to the first row. In this way, when the battery-swapping vehicle 03 is swapping batteries, there is no need to move the battery box 02 in the second row with a power less than the sixth set power, and then move the battery box 02 in the first row with a power greater than or equal to the sixth set power to the mounting seat 32, thereby reducing the battery swap time and improving the battery swap efficiency.

[0154] In this embodiment, the vehicle battery replacement method may further include step S27, which may include steps S271 to S274, which are described in detail below. Step S27 is performed after step S10 is completed.

[0155] Step S271, based on the state data being the seventh state and the low-power battery box 02 on the battery-swapping vehicle 03 being located in the battery-swapping area, the hoisting unit 11 moves the low-power battery box 02 on the battery-swapping vehicle 03 to the first row of rotating seats 122. The seventh state includes the battery box 02 on the second row of the second column battery holder unit 13 having a power level greater than or equal to a seventh set power level, the seventh set power level may be the same as the first set power level, the battery boxes 02 on the first column battery holder unit 13 and the second column first row battery holder unit 13 have power levels less than the battery boxes 02 on the second row of the second column battery holder unit 13, respectively, and the direction of the low-power battery box 02 on the battery-swapping vehicle 03 is the same as the direction of the battery box 02 on the first row of the battery holder unit 13.

[0156] Step S272, based on the hoisting unit 11, the battery box 02 with low power on the battery swap vehicle 03 is moved to the first row of rotating seats 122, and the hoisting unit 11 moves the battery box 02 in the second column and second row of battery seat units 13 to the second row of rotating seats 122.

[0157] Step S273, based on the lifting unit 11, the battery box 02 in the second column and second row of battery seat units 13 is moved to the second row of rotating seats 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 on the first row of rotating seats 122 is the same as the direction of the mounting seat 32.

[0158] Step S274, based on the rotating base 121 rotating 180° around the central axis of the rotating base 121, the battery box 02 on 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 of the battery replacement vehicle 03.

[0159] In this embodiment, the present invention provides a battery replacement system, 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.

[0160] The battery exchange assembly 01 may include a hoisting unit 11, a rotating unit 12, four battery holder units 13, a battery exchange area, and a control unit 15. The area projected downward from the moving range of the hoisting unit 11 includes a set area. The battery holder unit 13, the rotating unit 12, and the battery exchange area are arranged in sequence within the set area along the first direction. The four battery holder units 13 are divided into two columns along the first direction and into two rows along the second direction. The rotating unit 12 includes a rotating base 121 and two rotating seats 122. During the battery swapping process of the battery swapping vehicle 03, the rotating base 121 rotates around the central axis of the rotating base 121, and the rotating seat 122 is connected to the top of the rotating base 121. After grabbing the low-power battery box 02 on the battery swapping vehicle 03 and moving it to the rotating seat 122, the rotating seat 122 can be allowed to rotate smoothly to prevent the battery box 02 on the rotating seat 122 from falling. The two rotating seats 122 are arranged at intervals. In this way, when there are battery boxes 02 on both rotating seats 122, the hoisting unit 11 can avoid moving the battery box 02 on the rotating seat 122 and causing damage to the battery box 02. The width of the battery swapping area is greater than or equal to the width of the battery box 02 and less than twice the width of the battery box 02. The distance between the symmetry plane of the battery swapping area in the second direction and the symmetry plane of any row of battery seat units 13 in the second direction along the second direction is less than a set value, and the set value can be 10cm to 20cm. The control unit 15 is connected to the hoisting unit 11. In this way, the control unit 15 can locate the battery box 02 on the battery swap vehicle 03, identify whether the battery box 02 on the battery swap vehicle 03 has entered the battery swap area, and control the movement of the hoisting unit 11 and obtain the power of the battery box 02. The four battery boxes 02 are detachably connected to any four of the battery seat units 13 and the rotating seat 122.

[0161] A can be the distance between the hanging unit 11 and the battery seat unit 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 up and down directions shown, B<A can provide the hoisting unit 11 with enough space for the battery box 02 in the third direction to realize the disassembly and installation of the battery box 02 and the battery seat unit 13, and A<2*B can avoid excessive redundancy of height space, thereby reducing excessive redundancy of the moving range of the hoisting unit 11 along the third direction. L can be the length of the battery box 02, and C can be the distance between the battery exchange area and any rotating seat 122 along the first direction. 0≤C<T*L, 1≤T≤1.1, which can reduce the moving path of the hoisting unit along the first direction. K can be the width of the battery box 02. D can be the minimum distance between the first row of battery seat units 13 and the set area on one side along the second direction. 0≤D<T*K, thus limiting the distance between the first row of battery seat units 13 and the set area on one side along the second direction, can reduce the moving path of the hoisting unit along the second direction, thereby reducing the size of the hoisting unit along the second direction. E can be the minimum spacing between the second row of battery holder units 13 and one side of the set area along the second direction, where 0 ≤ E < T*K. Limiting the spacing between the second row of battery holder units 13 and one side of the set area along the second direction can further reduce the travel path of the suspension unit along the second direction, thereby reducing the size of the suspension unit along the second direction. F can be the minimum spacing between the first row of battery holder units 13 and the second row of battery holder units 13, where 0 ≤ F < T*K. This allows for a closer spacing between the first row of battery holder units 13 and the second row of battery holder units 13, thereby reducing the travel path of the suspension unit along the second direction and, in turn, reducing the size of the suspension unit along the second direction.

[0162] The battery swapping vehicle 03 may include a vehicle body 31 and a mounting base 32. The vehicle body 31 may be detachably and electrically connected to the mounting base 32. The battery box 02 may be detachably and electrically connected to the mounting base 32, and the vehicle body 31 may obtain electrical energy through the mounting base 32, thereby driving the vehicle body 31 to travel normally on the road.

[0163] In other embodiments, the battery exchange system may further include a power delivery vehicle 14, which is detachably connected to the battery seat unit 13. In this way, the battery box 02 components and the battery seat unit 13 in the set area are transported and replaced by the power delivery vehicle 14, and no charger is set in the set area, thereby reducing the construction cost of the battery exchange system. G is the distance between any row of battery seat units 13 and the rotating seat 122 along the second direction, 0≤G<T*L, which can further reduce the moving path of the hoisting unit along the second direction, so that the distance between each component is more compact. 0≤G<T*K, which limits the distance between the battery seat unit 13 and the rotating seat 122, reduces the moving path of the hoisting unit along the first direction, and thus reduces the size of the hoisting unit along the first direction. 0≤M<T*K, where M is the spacing between adjacent battery holder units 13 in the first row, and 0≤N<T*K, where N is the spacing between adjacent battery holder units 13 in the second row. This limits the spacing between adjacent battery holders in the first and second rows, reducing the travel path of the lifting unit along the first direction, thereby reducing the size of the lifting unit along the first direction. The distance between the plane of symmetry of one rotating seat 122 in the second direction and the plane of symmetry of the battery holder units 13 in the first row in the second direction is less than a set value; the distance between the plane of symmetry of another rotating seat 122 in the second direction and the plane of symmetry of the battery holder units 13 in the second row in the second direction is less than a set value, which can be 10 cm to 20 cm.

[0164] 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 unit 13, respectively, and the other end may extend away from the battery holder unit 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 unit 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.
