Description

Technical Field

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

[0002] The mobile battery swap system uses a mobile platform to load the battery box, which can be moved to the battery swap area on the road by a tractor to carry out the battery swap operation; the mobile platform is loaded with sliding and lifting mechanisms, etc., which can grab the battery box and move it between the mobile platform and the battery swap vehicle to complete the battery swap operation. The location of the battery swap station is fixed, and the battery swap vehicle cannot be swapped anytime and anywhere; in the face of some short-term / temporary battery swap needs, the cost of building a battery swap station is high; the mobile battery swap method is a good solution to problems such as the out-of-town operation of electric engineering machinery, emergency battery swapping of ordinary vehicles, and the need for temporary battery swap stations for reconstruction in disaster areas.

[0003] At present, the mobile battery exchange system mainly adopts two solutions: battery exchange on the side of the mobile platform and battery exchange at the rear of the mobile platform. Since the mobile platform needs to be transferred through the road from one battery exchange area to another, traffic regulations limit the width of the mobile platform to a set range. Therefore, in order to load more battery boxes, the length of the mobile platform is often increased. However, heavy vehicles such as vans and trucks require battery boxes with larger capacity and weight due to cargo and long-distance transportation requirements. If the battery is exchanged on the side of the mobile platform, it is easy to roll over and the safety is poor. Due to the limited space on the mobile platform in the mobile battery exchange system, the number of battery boxes loaded is limited. At the same time, in order to reserve a channel for transporting the battery boxes on the mobile platform to the battery exchange vehicle, the space occupied by the battery boxes will be further squeezed.

[0063] In this embodiment, in order to improve the battery replacement capacity of the platform assembly 01, two rows of battery boxes 13 are arranged along the length direction of the movable platform 11. The platform assembly 01 needs to move on the road from one area to another battery replacement area. Traffic regulations stipulate the upper limit of the width of vehicles traveling on the road, so the width of the platform assembly 01 is limited. When two rows of battery boxes 13 are loaded on the movable platform 11, the reserved space cannot meet the second sliding unit 14 driving the hoist 15 to grab the battery box 13 and pass smoothly, and cannot meet the needs of battery replacement work at the rear of the movable platform 11. Therefore, a mobile battery replacement method is proposed.

[0064] Among them, Figure 2 As shown, the mobile battery swap system includes a platform component 01 and a battery swap vehicle 02. Figure 6As shown, the platform assembly 01 includes a movable platform 11, a first sliding unit 12, a battery box 13, a second sliding unit 14, and a hanger 15. The first sliding unit 12 includes a first slide rail 121, a charging seat 122, and a first driving unit. Figure 4 As shown, the first slide rail 121 is detachably connected to the movable platform 11 along the width direction of the movable platform 11. The charging seat 122 is slidably connected to the first slide rail 121. A first sliding unit 12 includes two charging seats 122. The first driving unit is detachably connected to the movable platform 11. The first driving unit is drivingly connected to the charging seat 122, and the first driving unit drives the charging seat 122 to reciprocate along the width direction of the platform assembly 01, and controls the distance moved by the charging seat 122. The battery box 13 is detachably connected to the charging seat 122. The battery box 13 is electrically connected to the charging seat 122, so that the battery box 13 is charged through the charging seat 122. The second sliding unit 14 is detachably connected to the movable platform 11. The second sliding unit 14 is located on the side of the battery box 13 away from the first sliding unit 12, that is, the second sliding unit 14 is located on the upper side of the battery box 13 in height. The second sliding unit 14 moves the battery box 13 from the charging seat 122 of the movable platform 11 to the battery-swapping vehicle 02 through the lifting device 15, or moves the battery box 13 from the battery-swapping vehicle 02 to the idle charging seat 122 of the movable platform 11. Figure 4 As shown, the battery-swapping vehicle 02 includes a vehicle body 21 and a battery-swapping seat 22. The vehicle body 21 is detachably connected to the battery-swapping seat 22. The battery-swapping seat 22 is detachably connected to the battery box 13. The battery-swapping seat 22 is electrically connected to the battery box 13, and when the battery box 13 is placed on the battery-swapping seat 22, the battery box 13 provides power for the vehicle body 21 to travel. The battery-swapping vehicle 02 includes a battery-swapping state, and the battery-swapping state includes the battery-swapping seat 22 of the battery-swapping vehicle 02 being located on one side of the length direction of the movable platform 11 (that is, the battery-swapping seat 22 of the battery-swapping vehicle 02 is located on the tail side of the movable platform 11), and the battery-swapping seat 22 is located on the symmetry axis of the movable platform 11 along the length direction, so that the second sliding unit 14 can facilitate placing the battery box 13 of the platform assembly 01 on the battery-swapping seat 22 of the battery-swapping vehicle 02.

[0065] like Figure 1 As shown, the mobile battery replacement method includes:

[0066] Step S10, based on the platform component 01, move to the battery replacement area, such as Figure 4 As shown, the first driving unit drives the two rows of battery boxes 13 of the platform assembly 01 to move to the first set position respectively toward the two sides of the width direction of the platform assembly 01, and the first driving unit drives the idle charging seat 122 to move to the middle position of the width direction of the platform assembly 01 to the second set position. Figure 5As shown, the first setting position includes battery boxes 13 located on both sides of the width direction of the platform component 01, and the second setting position includes battery boxes 13 located in the middle of the width direction of the platform component 01; the battery box 13 located at the second setting position passes through the gap between the two aligned battery boxes 13 located at the first setting position along the length direction of the platform component 01. Aligned battery boxes 13 refer to two battery boxes 13 located on both sides of the width direction of the platform component 01, and the distances between the two battery boxes 13 and the battery swap vehicle 02 are equal. Before the platform component 01 is transferred to the area, as shown in FIG. Figure 3 As shown, the two rows of battery boxes 13 of the driving platform assembly 01 move toward the middle position along the width direction of the platform assembly 01, thereby improving the safety and stability of the vehicle during driving. The number of charging seats is 2n, and the number of battery boxes of the platform assembly is initially 2n-1, n≥2, and n is a positive integer.

[0067] Step S20, based on the platform assembly 01 being stationary in the battery swapping area, the second sliding unit 14 drives the hoist 15 to grab the battery box 13 on the battery swapping seat 22 of the battery swapping vehicle 02.

[0068] Step S30, based on the two rows of battery boxes 13 of the platform assembly 01 being moved to the first set position, a battery exchange channel is formed between the two rows of battery boxes 13 of the platform assembly 01, and the width of the battery exchange channel is sufficient for the battery box 13 at the second set position to pass through, and the hoist 15 grabs the battery box 13 on the battery exchange vehicle 02 and moves along the battery exchange channel toward the idle charging seat 122.

[0069] Step S40, based on the idle charging seat 122 moving to the second set position, the hoist 15 places the captured battery box 13 on the battery-swap vehicle 02 on the idle charging seat 122.

[0070] Step S50, based on the lifting device 15 lowering the battery box 13 on the battery swap vehicle 02, the lifting device 15 grabs the battery box 13 of the platform assembly 01 and moves it to the battery swap seat 22 of the battery swap vehicle 02. Among them, the battery box 13 on the battery swap vehicle 02 lowered by the lifting device 15 is a battery box 13 in a low-power state, and the battery box 13 of the platform assembly 01 grabbed and moved by the lifting device 15 to the battery swap seat 22 of the battery swap vehicle 02 is a battery box 13 in a high-power state. By arranging two rows of battery boxes 13 in the width direction of the platform assembly 01, after arriving at the battery swapping area, the battery boxes 13 move to both sides to the first set position, leaving the battery swapping channel in the middle, so that the second sliding unit 14 grabs the battery box 13 of the battery swapping vehicle 02 through the battery swapping channel and places it in the vacant charging seat 122 at the second set position, and grabs the battery box 13 of the platform assembly 01 at the second set position and moves it to the battery swapping seat 22 of the battery swapping vehicle 02 through the battery swapping channel, thereby successfully completing the battery swapping process and improving the battery swapping capacity of the vehicle.

[0071] In other embodiments, in addition to charging the low-power battery box through the charging seat of the platform component, the low-power battery box is also lowered to the centralized charging area for centralized charging through the centralized charging station, and the battery box with high power is reloaded to continue the mobile charging operation.

[0072] In this embodiment, step S50 includes:

[0073] In step S51 , based on the lifting device 15 putting down the battery box 13 in a low-power state, the lifting device 15 moves to the top of the battery box 13 in a high-power state to be grasped and grasps the battery box 13 in a high-power state.

[0074] Step S52, based on the hoist grabbing the battery box in multiple power states, obtain the position state of the battery box in multiple power states close to the platform assembly on one side of the battery swapping vehicle. The position state includes that the battery box in multiple power states close to the platform assembly on one side of the battery swapping vehicle is partially located or all located at the first set position.

[0075] Step S53, based on the battery box part of the platform assembly on the side of the battery box with multiple power states close to the battery swapping vehicle being located at the first set position, the battery box on the side of the battery box with multiple power states close to the battery swapping vehicle and being in the second set position is driven to move to the first set position.

[0076] Step S54, based on the battery boxes in multiple power states, the battery boxes of the platform assembly on the side of the battery swapping vehicle are all located at the first set position, and the hoist drives the battery boxes in multiple power states to move above the battery swapping seat of the battery swapping vehicle. Step S55, based on the battery boxes 13 in multiple power states, move to above the battery swapping seat 22 of the battery swapping vehicle 02, and obtain the inclination angle of the platform assembly 01 along the width direction.

[0077] Step S56, based on the fact that the tilt angle of the platform assembly 01 along the width direction is outside the set range, the tilt angle of the platform assembly 01 along the width direction is adjusted to be within the set range by moving the charging seat 122. When the tilt angle of the platform assembly 01 along the width direction is outside the set range, the number of battery boxes 13 arranged on one side of the platform assembly 01 along the width direction is relatively small, and the number of battery boxes 13 arranged on the other side of the platform assembly 01 along the width direction is relatively large.

[0078] Step S57, based on the fact that the tilt angle of the platform component 01 along the width direction is within the set range, the battery box 13 in multiple power states is placed on the battery exchange seat 22 of the battery exchange vehicle 02. After the battery box 13 in multiple power states is moved to the top of the battery exchange seat 22 of the battery exchange vehicle 02, the platform component 01 is adjusted to a horizontal state so that the battery box 13 in multiple power states is directly opposite to the battery exchange seat 22 of the battery exchange vehicle 02, so as to facilitate the smooth placement of the battery box 13 on the battery exchange seat 22 and avoid damage to the battery box 13 or the battery exchange seat 22. In this embodiment, in step S56, the moving charging seat 122 adjusts the tilt angle of the platform component 01 along the width direction to within the set range, including: driving the battery box 13 on the heavier side of the platform component 01 to move toward the middle position along the width direction of the platform component 01 by the first driving unit, so that the weight of the battery boxes 13 on both sides of the width direction of the platform component 01 is equal or nearly equal, so that the tilt angle of the platform component 01 along the width direction is within the set range, that is, adjusting the platform component 01 to a horizontal or nearly horizontal state.

[0079] In this embodiment, step S51 includes step S511, and step S511 includes:

[0080] Step S5111 : based on the lifting device 15 putting down the battery box 13 in a low-power state, the position of the battery box 13 in a high-power state to be grasped is obtained.

[0081] Step S5112: Based on the fact that the distance between the battery box 13 in a high-power state to be grabbed and the battery swap vehicle 02 is greater than the distance between the battery box 13 in a low-power state and the battery swap vehicle 02, and the battery box 13 in a high-power state to be grabbed is located on the heavier side of the platform component 01, the battery box 13 in a high-power state to be grabbed is driven to move to the second set position along the width direction of the platform component 01 toward the middle position. Thus, the inclination angle of the platform component 01 along the width direction is within the set range, so that the sling 15 is directly opposite to the battery box 13 in a fully-charged state to be grabbed, which is convenient for the sling 15 to grab the battery box 13 in a fully-charged state and avoid shaking of the battery box 13 during the grabbing process.

[0082] Step S5113, based on the battery box 13 in a multi-power state to be grabbed, moves toward the middle position to the second set position along the width direction of the platform component 01, and the hoist 15 grabs the battery box 13 in a multi-power state. After the hoist 15 puts down the battery box 13 in a low-power state, the distance between the battery box 13 in a multi-power state to be grabbed and the battery swap vehicle 02 is greater than the distance between the battery box 13 in a low-power state and the battery swap vehicle 02, and the battery box 13 in a multi-power state to be grabbed is located on the heavier side of the platform component 01, the inclination angle of the platform component 01 along the width direction is adjusted within the set range, and then the battery box 13 in a multi-power state is grabbed, ensuring that the hoist 15 and the battery box 13 are facing each other during the grabbing process, so as to smoothly grab the battery box 13 and avoid the battery box 13 from shaking during the grabbing process.

[0085] Step S5122, based on the fact that the distance between the battery box 13 in a high-power state to be grabbed and the battery-swapping vehicle 02 is greater than the distance between the battery box 13 in a low-power state and the battery-swapping vehicle 02, and the battery box 13 in a high-power state to be grabbed is located on the lighter side of the platform component 01, the battery box 13 in a low-power state is driven to move to the first set position along the width direction of the platform component 01 toward the idle side, the non-aligned battery box 13 on the opposite side of the battery box 13 in a high-power state to be grabbed is driven to move to the second set position along the width direction of the platform component 01 toward the middle position, and the battery box 13 in a high-power state to be grabbed is driven to move to the second set position along the width direction of the platform component 01 toward the middle position. Thus, the inclination angle of the platform component 01 along the width direction is within the set range, and the hoist 15 is directly opposite to the battery box 13 in a fully-charged state to be grabbed, so that the hoist 15 can grab the battery box 13 in a fully-charged state and avoid shaking of the battery box 13 during the grabbing process. Among them, the difference between the distance from the non-aligned battery box 13 on the opposite side of the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 and the distance from the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 is outside the set range, that is, the distance from the non-aligned battery box 13 on the opposite side of the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 is not equal to the distance from the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02, thereby avoiding interference with the movement of the battery box 13 in multiple electrical states to be grasped to the second set position.

[0086] Step S5123, based on the battery box 13 in multiple power states to be grabbed, moves to the second set position, and the hoist 15 grabs the battery box 13 in multiple power states. After the hoist 15 puts down the battery box 13 in low power state, the distance between the battery box 13 in multiple power states to be grabbed and the battery swap vehicle 02 is greater than the distance between the battery box 13 in low power state and the battery swap vehicle 02, and the battery box 13 in multiple power states to be grabbed is located on the lighter side of the platform component 01, the inclination angle of the platform component 01 along the width direction is adjusted within the set range, and then the battery box 13 in multiple power states is grabbed, ensuring that the hoist 15 and the battery box 13 are facing each other during the grabbing process, so as to smoothly grab the battery box 13 and avoid the battery box 13 from shaking during the grabbing process.

[0087] In this embodiment, step S51 includes step S513, and step S513 includes:

[0088] Step S5131 : based on the lifting device 15 putting down the battery box 13 in a low-power state, the position of the battery box 13 in a high-power state to be grasped is obtained.

[0089] Step S5132: Based on the fact that the distance between the battery box 13 in a high-power state to be grabbed and the battery swap vehicle 02 is shorter than the distance between the battery box 13 in a low-power state and the battery swap vehicle 02, and the battery box 13 in a high-power state to be grabbed is located on the heavier side of the platform component 01, the battery box 13 in a high-power state to be grabbed is driven to move to the second set position along the width direction of the platform component 01 toward the middle position. Thus, the inclination angle of the platform component 01 along the width direction is within the set range, and the hoist 15 is directly opposite to the battery box 13 in a fully-charged state to be grabbed, so that the hoist 15 can grab the battery box 13 in a fully-charged state and avoid shaking of the battery box 13 during the grabbing process.

[0090] Step S5133, based on the battery box 13 in a multi-power state to be grabbed, moves toward the middle position to the second set position along the width direction of the platform component 01, and the hoist 15 grabs the battery box 13 in a multi-power state. After the hoist 15 puts down the battery box 13 in a low-power state, the distance between the battery box 13 in a multi-power state to be grabbed and the battery swap vehicle 02 is shorter than the distance between the battery box 13 in a low-power state and the battery swap vehicle 02, and the battery box 13 in a multi-power state to be grabbed is located on the heavier side of the platform component 01, the inclination angle of the platform component 01 along the width direction is adjusted within the set range, and then the battery box 13 in a multi-power state is grabbed, ensuring that the hoist 15 and the battery box 13 are facing each other during the grabbing process, so as to smoothly grab the battery box 13 and prevent the battery box 13 from shaking during the grabbing process.

[0091] In this embodiment, step S51 includes step S514, and step S514 includes:

[0092] Step S5141 : based on the lifting device 15 putting down the battery box 13 in a low-power state, the position of the battery box 13 in a high-power state to be grasped is obtained.

[0093] Step S5142, based on the fact that the distance between the battery box 13 in a high-power state to be grabbed and the battery-swapping vehicle 02 is shorter than the distance between the battery box 13 in a low-power state and the battery-swapping vehicle 02, and the battery box 13 in a high-power state to be grabbed is located on the lighter side of the platform component 01, the battery box 13 in a low-power state is driven to move to the first set position along the width direction of the platform component 01 toward the idle side, the non-aligned battery box 13 on the opposite side of the battery box 13 in a high-power state to be grabbed is driven to move to the second set position along the width direction of the platform component 01 toward the middle position, and the battery box 13 in a high-power state to be grabbed is moved to the second set position along the width direction of the platform component 01 toward the middle position. Thus, the inclination angle of the platform component 01 along the width direction is within the set range, and the hoist 15 is directly opposite to the battery box 13 in a fully-charged state to be grabbed, so that the hoist 15 can grab the battery box 13 in a fully-charged state and avoid shaking of the battery box 13 during the grabbing process. Among them, the difference between the distance from the non-aligned battery box 13 on the opposite side of the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 and the distance from the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 is outside the set range, that is, the distance from the non-aligned battery box 13 on the opposite side of the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 is not equal to the distance from the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02, thereby avoiding interference with the movement of the battery box 13 in multiple electrical states to be grasped to the second set position.

[0094] Step S5143, based on the battery box 13 in a multi-power state to be grabbed, moves toward the middle position to the second set position along the width direction of the platform component 01, and the hoist 15 grabs the battery box 13 in a multi-power state. After the hoist 15 puts down the battery box 13 in a low-power state, the distance between the battery box 13 in a multi-power state to be grabbed and the battery swap vehicle 02 is smaller than the distance between the battery box 13 in a low-power state and the battery swap vehicle 02, and the battery box 13 in a multi-power state to be grabbed is located on the lighter side of the platform component 01, the inclination angle of the platform component 01 along the width direction is adjusted within the set range, and then the battery box 13 in a multi-power state is grabbed, ensuring that the hoist 15 and the battery box 13 are facing each other during the grabbing process, so as to smoothly grab the battery box 13 and prevent the battery box 13 from shaking during the grabbing process.

[0095] In this embodiment, step S51 includes step S515, and step S515 includes:

[0096] Step S5151 , based on the lifting device 15 putting down the battery box 13 in a low-power state, the position of the battery box 13 in a high-power state to be grasped is obtained.

[0097] Step S5152, based on the fact that the distance between the battery box 13 in a high-power state to be grabbed and the battery-swapping vehicle 02 is equal to the distance between the battery box 13 in a low-power state and the battery-swapping vehicle 02, the battery box 13 in a low-power state is driven to move to the first set position along the width direction of the platform component 01 toward the idle side, the non-aligned battery box 13 on the opposite side of the battery box 13 in a high-power state to be grabbed is driven to move to the second set position along the width direction of the platform component 01 toward the middle position, and the battery box 13 in a high-power state to be grabbed is moved to the second set position along the width direction of the platform component 01 toward the middle position. Thus, the inclination angle of the platform component 01 along the width direction is within the set range, so that the hoist 15 is directly opposite to the battery box 13 in a fully-charged state to be grabbed, which facilitates the hoist 15 to grab the battery box 13 in a fully-charged state and avoids shaking of the battery box 13 during the grabbing process. Among them, the difference between the distance from the non-aligned battery box 13 on the opposite side of the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 and the distance from the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 is outside the set range, that is, the distance from the non-aligned battery box 13 on the opposite side of the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02 is not equal to the distance from the battery box 13 in multiple electrical states to be grasped to the battery swapping vehicle 02, thereby avoiding interference with the movement of the battery box 13 in multiple electrical states to be grasped to the second set position.

[0098] Step S5153, based on the battery box 13 in a high-power state to be grabbed, the hoist 15 moves toward the middle position to the second set position along the width direction of the platform component 01, and grabs the battery box 13 in a high-power state. After the hoist 15 puts down the battery box 13 in a low-power state, the distance from the battery box 13 in a high-power state to be grabbed to the battery swap vehicle 02 is equal to the distance from the battery box 13 in a low-power state to the battery swap vehicle 02, and the inclination angle of the platform component 01 along the width direction is adjusted within the set range, and then the battery box 13 in a high-power state is grabbed, ensuring that the hoist 15 and the battery box 13 are facing each other during the grabbing process, so as to smoothly grab the battery box 13 and prevent the battery box 13 from shaking during the grabbing process.

[0099] In this embodiment, step S20 includes:

[0100] Step S21, based on the platform component 01 being stationary in the battery exchange area, obtain the inclination angle of the platform component 01 along the width direction.

[0101] Step S22, based on the fact that the tilt angle of the platform component 01 along the width direction is outside the set range, the non-aligned battery box 13 of the battery box 13 in a multi-power state to be grasped on the heavier side of the platform component 01 is driven to move toward the middle position along the width direction of the platform component 01 until the tilt angle of the platform component 01 along the width direction is within the set range. By adjusting the tilt angle of the platform component 01 along the width direction within the set range, the hoist 15 is made to face the battery box 13 of the battery swap vehicle 02 to be grasped, so that the hoist 15 can grasp the battery box 13 on the battery swap seat 22 of the battery swap vehicle 02, and avoid shaking of the battery box 13 during the grasping process, which may cause damage to the docking mechanism of the battery box 13 or the battery swap seat 22. Among them, the difference between the distance from the non-aligned battery box 13 of the battery box 13 in multiple electrical states to be grasped to the battery swap vehicle 02 and the distance from the battery box 13 in multiple electrical states to be grasped to the battery swap vehicle 02 is outside the set range, that is, the distance from the non-aligned battery box 13 on the opposite side of the battery box 13 in multiple electrical states to be grasped to the battery swap vehicle 02 is not equal to the distance from the battery box 13 in multiple electrical states to be grasped to the battery swap vehicle 02, thereby avoiding the battery box 13 in multiple electrical states to be grasped at the second set position.

[0102] Step S23, based on the inclination angle of the platform component 01 along the width direction being within the set range, the second sliding unit 14 drives the sling 15 to grab the battery box 13 on the battery swap vehicle 02. Before driving the sling 15 to grab the battery box 13 in multiple power states, adjust the platform component 01 to a horizontal state so that the sling 15 is directly opposite to the battery box 13 in multiple power states, so as to facilitate the smooth grabbing of the battery box 13 by the sling 15, and also avoid the battery box 13 from shaking during the process of the sling 15 grabbing the battery box 13, so as to avoid damage to the battery box 13 or the charging seat 122.

[0103] In this embodiment, step S40 includes:

[0104] Step S41, based on the idle charging seat 122 moving to the second set position, the inclination angle of the platform component 01 along the width direction is obtained.

[0105] Step S42, based on the fact that the inclination angle of the platform component 01 along the width direction is outside the set range, the non-aligned battery box 13 of the idle charging seat 122 on the heavier side of the platform component 01 is driven to move toward the middle position along the width direction of the platform component 01 until the inclination angle of the platform component 01 along the width direction is within the set range. By adjusting the inclination angle of the platform component 01 along the width direction to be within the set range, the hoist 15 is made to face the idle charging seat 122, so that the hoist 15 can place the captured battery box 13 in a low-power state of the battery-swapping vehicle 02 on the idle charging seat 122, and avoid damage to the battery box 13 or the charging seat 122 due to misalignment of the battery box 13 and the charging seat 122 during the placement process. Among them, the difference between the distance from the non-aligned battery box 13 of the idle charging seat 122 to the battery-swapping vehicle 02 and the distance from the battery box 13 in a high-power state to be captured to the battery-swapping vehicle 02 is outside the set range. That is, the distance from the non-aligned battery box 13 of the idle charging seat 122 to the battery-swap vehicle 02 is not equal to the distance from the idle charging seat 122 (or the low-power battery box 13 to be placed) to the battery-swap vehicle 02, thereby avoiding the idle charging seat 122 (or the low-power battery box 13 to be placed) in the second set position.

[0106] Step S43, based on the inclination angle of the platform component 01 along the width direction being within the set range, the hoist 15 stably places the grabbed low-power battery box 13 on the idle charging seat 122. After the low-power battery box 13 of the battery swapping vehicle 02 is grabbed by the hoist 15 and moved to the top of the idle charging seat 122 of the platform component 01, the platform component 01 is first adjusted to a horizontal state so that the battery box 13 is directly opposite to the idle charging seat 122 of the platform component 01, so as to smoothly place the battery box 13 on the idle charging seat 122 and avoid damaging the battery box 13 or the charging seat 122.
