Description

Technical Field

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

[0002] Currently, battery swap stations generally utilize a top-lifting method to swap batteries in vehicles using lifting equipment. This lifting equipment primarily consists of a drive system, a lifting assembly, a track mechanism, and a control system. The drive system uses a motor to drive the lifting assembly along a pre-set track. The lifting assembly is equipped with a servo-driven lifting mechanism that adapts to gripping interfaces for batteries of varying specifications. During the battery swap process, the lifting assembly identifies the coordinates of the vehicle's battery swap port and controls its movement along the pre-set track, enabling precise positioning and rapid assembly and disassembly of the battery box from the station onto the vehicle.

[0003] However, during the deployment of battery swap stations, due to the structural limitations and space planning requirements of specific sites, the lifting equipment and track travel mechanisms of the stations were subject to strict installation height restrictions. Because the lifting equipment and track travel mechanisms were limited by the insufficient overhead space within the station, it was impossible to lift the batteries to the required height for movement. Consequently, the batteries could not be removed from the station, ultimately disrupting the entire battery swap process. Summary of the Invention

[0064] In this embodiment, when the current battery swap station performs battery replacement in a highly restricted operating environment, the movement of the battery box 02 cannot be completed due to the conflict between the spatial layout of the equipment in the battery swap station and the moving path of the hoisting unit 11. Specifically, when the battery swap vehicle 03 enters the battery swap area, the hoisting unit 11 needs to perform the grabbing and placing actions of the battery box 02 between the set area and the battery swap area. However, under the height restriction condition, the vertical moving space of the hoisting unit 11 in the traditional layout cannot cover the access requirements of multiple rows of battery holders 13 in the battery swap station and the vehicle docking requirements in the battery swap area. Therefore, in order to solve the above problems, such as Figure 1 As shown, the present invention provides a vehicle battery replacement method.

[0065] The vehicle battery replacement system is applied to the vehicle battery replacement method. The vehicle battery replacement system may include a battery replacement component 01, a battery box 02, and a battery replacement vehicle 03.

[0066] The battery exchange component 01 may include a hoisting unit 11, a rotating unit 12, X battery holders 13, a battery exchange area, and a control unit 15. The area projected downward from the moving range of the hoisting unit 11 may include a set area and a battery exchange area. The set area may include a first area and a battery exchange channel, and the first area and the battery exchange channel may be arranged in sequence along the second direction. The battery holder 13 and the rotating unit 12 are arranged in the first area, and the battery holder 13, the rotating unit 12, and the battery exchange area are arranged in sequence along the first direction. The X battery holders 13 are divided into at least two columns along the first direction and into two rows along the second direction, and X ≥ 4. The first direction may be the length direction of the battery holder 13, that is, Figure 2 The left and right directions shown in FIG. 1 and the second direction may be the width direction of the battery holder 13, that is, Figure 2 The up and down directions shown. The battery holders 13 are arranged in a matrix manner to make full use of the space in the battery swap station. The rotating unit 12 may include a rotating base 121 and two rotating bases 122. The rotating base 121 rotates around the central axis of the rotating base 121, and the rotating base 122 is connected to the top of the rotating base 121, and the two rotating bases 122 are arranged at intervals. In the second direction, the distance between the symmetry plane of one rotating base 122 and the symmetry plane of a row of battery holders 13 in the second direction is less than a set value, and the set value can be 10cm to 20cm. The distance between the symmetry plane of another rotating base 122 in the second direction and the symmetry plane of another row of battery holders 13 in the second direction is less than a set value. In this way, the rotating base 122 and the charging base are in the same row as much as possible, which is more conducive to the installation and disassembly of the battery box 02 by the hoisting unit 11. 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, so that when the battery box 02 is detachably connected to the battery holder 13, the battery box 02 is within the area where the battery holder 13 is projected in the direction close to the battery box 02; when the battery box 02 is detachably connected to the rotating seat 122, the battery box 02 is within the area where the rotating seat 122 is projected in the direction close to the battery box 02. The control unit 15 is connected to the hoisting unit 11. The number of battery boxes 02 is the same as the number of battery holders 13, and X battery boxes 02 are detachably connected to any X of the battery holders 13 and the rotating seat 122. The control unit 15 can also obtain the position of the battery box 02 on the battery swap vehicle 03 in the battery swap area, control the moving path and movement of the hoisting unit 11, rotate the rotating unit 12, and obtain the power of the battery box 02 in the battery holder 13.

[0067] A can be the distance between the hanging unit 11 and the battery holder 13 along the third direction, and B can be the height of the battery box 02. The third direction can be the height direction of the battery box 02, that is, Figure 4In the vertical direction shown, B < A allows sufficient space for the hoisting unit 11 to remove and install the battery box 02 and the battery holder 13 in the third direction. A < 2 × B avoids excessive space for the hoisting unit 11 to move in the third direction, thereby reducing the volume of the hoisting unit 11. C is the distance between the battery swap area and any rotating holder 122 along the first direction, and L is the length of the battery box 02. 0 ≤ C < T × L, 1 ≤ T ≤ 1.1. By limiting the distance between the battery swap area and any rotating holder 122 along the first direction, the range of movement of the hoisting unit 11 in the first direction is reduced, thereby reducing the volume of the hoisting unit 11 in the first direction. D is the distance between the second row of battery holders 13 in the first area and the side of the first area away from the battery swap channel. K is the width of the battery box 02. 0 ≤ D < T × K. By limiting the distance between the second row of battery holders 13 and the side of the first area away from the battery swap channel, the range of movement of the hoisting unit 11 in the second direction is reduced, thereby reducing the volume of the hoisting unit 11 in the second direction. E can be the distance between the first row of battery holders 13 in the first area and the side of the battery exchange channel away from the first area, E>K, so that the battery box can pass through the battery exchange channel, thereby quickly exchanging batteries. F can be the minimum distance between the first row of battery holders 13 and the second row of battery holders 13, 0≤F<T×K. By limiting the minimum distance between the first row of battery holders 13 and the second row of battery holders 13, the movement range of the hoisting unit 11 along the second direction is further reduced, thereby reducing the volume of the hoisting unit 11 along the second direction. Finally, by using the battery exchange channel as a moving channel and the rotating unit 12 as a transfer component, the battery exchange vehicle 03 can be replaced, and the moving path of the hoisting unit 11 can be shortened, thereby improving the battery exchange efficiency and reducing the volume of the hoisting unit 11.

[0068] The battery-swap vehicle 03 may include a vehicle body 31 and a mounting base 32. The vehicle body 31 and the mounting base 32 are detachably and electrically connected, and the battery box 02 is detachably and electrically connected to the mounting base 32. The vehicle body 31 can obtain electrical energy from the battery box 02 through the mounting base 32, thereby driving the battery-swap vehicle 03 to travel normally on the road.

[0069] The vehicle battery replacement method may include steps S10 to S30, and steps S10 to S30 will be described in detail below.

[0070] In step S10, upon arrival of the low-charge battery box 02 on the battery swapping vehicle 03 at the battery swapping area, status data can be obtained. The status data may include the charge level of the battery box 02 within the battery holder 13 and the location of the low-charge battery box 02 on the battery swapping vehicle 03. By obtaining the location and charge level data of the battery box 02, a data foundation can be provided for subsequent operations, thereby improving the accuracy of the battery swapping operation.

[0071] In step S20, based on the state data being in the first state, the hoisting unit 11 may move the low-charged battery box 02 on the battery swap vehicle 03 to the rotating seat 122 of the rotating unit 12, thereby reserving space on the mounting seat 32 to prepare for the subsequent battery swap step. The first state may include the battery box 02 in a row near the battery swap area in the first area being less charged than the battery boxes 02 in other battery seats 13. The rotating seat 122 is idle, that is, there is no battery box 02 on the rotating seat 122.

[0072] In step S30, based on the low-power battery box 02 moving to the rotating seat 122 of the rotating unit 12, the hoisting unit 11 can grab the battery box 02 in the battery holder 13 in a row away from the battery swap area in the first area and move it to the battery swap vehicle 03 through the battery swap channel. The battery box 02 in the battery holder 13 is moved to the battery swap channel by the hoisting unit 11, and then moved to the mounting seat 32 to complete the battery swap operation for the battery swap vehicle 03, thereby reducing the height requirement of the hoisting unit 11 and achieving rapid battery swap for the battery swap vehicle 03. Among them, the area projected downward from the movement range of the hoisting unit 11 may include a set area and a battery swap area. The set area and the battery swap area can be arranged in sequence along the first direction. The set area may include a first area and a battery swap channel. The first area and the battery swap channel can be arranged in sequence along the second direction. The battery holder 13 and the rotating unit 12 are arranged in the first area. The battery holder 13, the rotating unit 12, and the battery swap area are arranged in sequence along the first direction. The X battery holders 13 are divided into at least two columns along the first direction and two rows along the second direction. The battery box 02 is moved using the battery exchange channel, and the rotating unit 12 serves as a transfer platform to adjust the position of the battery box 02. Finally, the lifting unit 11 completes the battery exchange of the battery exchange vehicle 03 through the battery exchange channel when the movement along the third direction is restricted.

[0073] In this embodiment, the first state in step S20 may also include that the low-power battery box 02 on the battery-swapping vehicle 03 is located in the first position of the battery-swapping area, and the power of the battery box 02 in the first row of battery holders 13 in the first area away from the battery-swapping area is greater than the power of the battery box 02 in other battery holders 13. The first row may be a row close to the battery-swapping channel, and the distance between the symmetry plane of the first position in the second direction and the symmetry plane of the first row of battery holders 13 in the second direction along the second direction is less than the first set distance, and the first set distance may be 10cm to 20cm. The first position and the first row of battery holders 13 and a rotating seat 122 in the first area are located in the same row. In this way, by limiting the symmetry plane spacing condition, the moving distance of the hoisting unit 11 along the second direction can be reduced, thereby improving the position accuracy and efficiency of the battery-swapping operation.

[0074] Step S30 includes step S31 , and step S31 includes steps S311 to S312 . Steps S311 to S312 will be described in detail below.

[0075] In step S311, the low-power battery box 02 on the battery-swapping vehicle 03 is moved to the first row of rotating seats 122 based on the hoisting unit 11. The rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the hoisting unit 11 grabs the battery box 02 in the first row of battery seats 13 in the first area away from the battery-swapping area. The rotating base 121 and the hoisting unit 11 can operate simultaneously without interfering with each other, which can improve the efficiency of battery-swapping. By rotating the rotating base 121 180°, a moving channel for the battery box 02 is reserved on the first row of rotating seats 122, thereby preparing for the subsequent battery-swapping steps and facilitating the battery-swapping operation of the battery-swapping vehicle 03.

[0076] Step S312: Based on the rotating base 121 of the hoisting unit 11 rotating 180° around the central axis of the rotating base 121 and the rotating unit 12 grabbing the battery box 02 in the first row of battery holders 13 in the first area away from the battery swap area, the hoisting unit 11 moves the battery box 02 in the first row of battery holders 13 in the first area away from the battery swap area through the battery swap channel and above the first row of rotating seats 122 to the battery swap vehicle 03. By moving the battery box 02 in this way, the hoisting unit 11 can avoid collisions between the battery boxes 02. At the same time, moving the battery box 02 with sufficient power to the mounting seat 32 can provide a longer cruising range for the battery swap vehicle 03.

[0077] In this embodiment, the vehicle battery replacement method may further include step S21, which may include steps S211 to S219, which are described in detail below. Step S21 is performed after step S10 is completed.

[0078] Step S211, based on the state data being in the first state, the hoisting unit 11 moves the battery box 02 with the highest power in the first area, which is in the same row of the first battery holder 13, to the first row of rotating seats 122 through the battery exchange channel, to facilitate the subsequent battery exchange steps. Among them, the first state also includes the battery box 02 with low power on the battery exchange vehicle 03 being located in the first position of the battery exchange area, the power of the battery box 02 in the second row of battery holders 13 in the first area away from the battery exchange area is greater than the power of the battery box 02 in other battery holders 13, the first row of battery holders 13 can be a row close to the battery exchange channel, the second row of battery holders 13 can be a row away from the battery exchange channel, and the distance between the symmetry plane of the first position in the second direction and the symmetry plane of the first row of battery holders 13 in the second direction along the second direction is less than the first set distance, and the first set distance can be 10cm to 20cm. The lifting unit 11 grabs the battery box 02 in the first row away from the battery exchange area in the first area and moves faster, and the battery exchange channel is efficient. At the same time, the battery box 02 with higher power is preferentially moved to connect with the mounting seat 32, which can provide a longer cruising range for the battery exchange vehicle 03.

[0079] In step S212, based on the hoisting unit 11, the battery box 02 with the highest power in the first area and the battery box 02 in the same first row of battery seats 13 are moved to the first row of rotating seats 122 through the battery exchange channel. The rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the hoisting unit 11 grabs the battery box 02 with the highest power. By rotating the rotating base 121 180°, space is reserved on the first row of rotating seats 122 to prepare for subsequent battery exchange operations in advance.

[0080] Step S214, based on the rotating base 121 of the rotating unit 12 rotating 180° around the central axis of the rotating base 121 and the lifting unit 11 grabs the battery box 02 with the highest power, the lifting unit 11 moves the battery box 02 with the highest power through the battery exchange channel to the first row of rotating seats 122, and preferentially moves the battery box 02 with the highest power to the rotating seat 122, preparing in advance for the battery box 02 to be moved to the mounting seat 32.

[0081] In step S215, the battery box 02 with the highest power is moved to the first row of rotating seats 122 through the battery replacement channel based on the hoisting unit 11, and the rotating base 121 of the rotating unit 12 is rotated 180 degrees around the central axis of the rotating base 121. The first row of rotating seats 122 is located in the same row as the first row of battery boxes 02 in the first area.

[0082] Step S216, based on the rotating base 121 of the rotating unit 12 rotating 180 degrees around the central axis of the rotating base 121, the hoisting unit 11 moves the battery box 02 in the first row of rotating seats 122 to the vacant battery seat 13 in the first area through the battery swap channel. Priority is given to moving the battery box 02 on the first row of rotating seats 122 to the second row of battery seats 13 away from the battery swap area. In this way, when the battery box 02 removed from the battery swap vehicle 03 is moved to the charging seat, multiple moves to adjust the position of the battery box 02 can be avoided, thereby facilitating subsequent operation steps.

[0083] Step S217, based on the hoisting unit 11, the battery box 02 in the first row of rotating seats 122 is moved to the vacant battery seat 13 in the first area through the battery exchange channel, and the hoisting unit 11 moves the low-power battery box 02 on the battery exchange vehicle 03 to the first row of rotating seats 122. By moving the low-power battery box 02 on the battery exchange vehicle 03, space is reserved on the mounting seat 32, thereby facilitating the subsequent hoisting unit 11 to exchange batteries for the battery exchange vehicle 03.

[0084] Step S218: Based on the hoisting unit 11, the low-power battery box 02 on the battery-swapping vehicle 03 is moved to the first 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.

[0085] In step S219, the rotating base 121 of the rotating unit 12 rotates 180 degrees around the central axis of the rotating base 121, and the hoisting unit 11 moves the battery box 02 with the highest power on the first row of rotating seats 122 to the battery swap vehicle 03. By finally moving the high-power battery box 02 to connect with the battery swap vehicle 03, the energy supply demand of the battery swap vehicle 03 can be directly solved, providing the battery swap vehicle 03 with a longer driving range.

[0086] In this embodiment, the first state in step S20 may also include the low-power battery box 02 on the battery-swapping vehicle 03 being located in the second position of the battery-swapping area, the power of the battery box 02 in the first row of battery holders 13 in the first area away from the battery-swapping area being greater than the power of the battery box 02 in other battery holders 13, and the distance between the symmetry plane of the second position in the second direction and the symmetry plane of the battery-swapping channel in the second direction along the second direction being less than the first set distance, and the first set distance can be 10cm to 20cm, so that the hoisting unit 11 grabs the battery box 02 in the first row of a column away from the battery-swapping area in the first area and moves faster, and the battery-swapping channel is efficient.

[0087] Step S30 includes step S32, and step S32 includes steps S321 and S322. Steps S321 and S322 will be described in detail below.

[0088] Step S321, the low-power battery box 02 of the battery-swapping vehicle 03 is moved to the rotating seat 122, and the lifting unit 11 grabs the battery box 02 in the first row of battery seats 13 away from the battery-swapping area.

[0089] Step S322, based on the hoisting unit 11 grabbing the battery box 02 in the first row of battery holders 13 away from the battery exchange area, the hoisting unit 11 moves the battery box 02 in the first row of battery holders 13 away from the battery exchange area to the battery exchange vehicle 03 through the battery exchange channel. The hoisting unit 11 grabs the battery box 02 in the first row of battery holders 13 away from the battery exchange area in the first area, and the moving path is shorter, the battery exchange channel is efficient, and at the same time, the battery box 02 with higher power can provide a longer driving mileage for the battery exchange vehicle 03.

[0090] In this embodiment, the first state in step S20 may also include that the low-power battery box 02 on the battery-exchange vehicle 03 is located in the second position of the battery-exchange area, and the power of the battery box 02 in the second row of battery holders 13 in the first area away from the battery-exchange area is greater than the power of the battery box 02 in other battery holders 13, and the distance between the symmetry plane of the second position in the second direction and the symmetry plane of the battery-exchange channel in the second direction is less than the first set distance along the second direction, so that the second position and the battery-exchange channel are located in the same row, which can reduce the moving path of the hoisting unit 11 and thereby improve the battery-exchange efficiency.

[0091] Step S30 includes step S33, and step S33 includes steps S331 to S333. Steps S331 to S333 will be described in detail below.

[0092] In step S331, the battery box 02 with low power is moved to the first row of rotating seats 122. The rotating base 121 of the rotating unit 12 rotates 180 degrees around its central axis, and the lifting unit 11 grabs the battery box 02 in the first row of battery holders 13, which contains the battery box 02 with the highest power in the first area. The simultaneous operation of the lifting unit 11 and the rotating base 121 improves overall battery replacement efficiency and speed.

[0093] In step S332, the rotating base 121 of the rotating unit 12 rotates 180° around the central axis of the rotating base 121 and the hoisting unit 11 grabs the battery box 02 with the highest power in the first area and the battery box 02 in the first row of battery holders 13. The hoisting unit 11 moves the battery box 02 with the highest power in the first area and the battery box 02 in the first row of battery holders 13 through the battery exchange channel to the first row of rotating seats 122, so that the battery box 02 with the highest power will not be blocked when moving, thereby improving the efficiency of the hoisting unit 11 in moving the battery box 02.

[0094] Step S333, based on the hoisting unit 11, the battery box 02 with the highest power in the first area in the first row of battery seats 13 is moved to the first row of rotating seats 122 through the battery exchange channel. The hoisting unit 11 moves the battery box 02 with the highest power through the battery exchange channel to the battery exchange vehicle 03. The hoisting unit 11 grabs the battery box 02 in the first row of the column away from the battery exchange area in the first area and moves it faster. Moving the battery box 02 through the battery exchange channel is more efficient. At the same time, the battery box 02 with higher power is preferentially selected to be moved to connect with the mounting seat 32, which can provide a longer cruising range for the battery exchange vehicle 03.

[0095] In this embodiment, the vehicle battery replacement method further includes step S22, which includes steps S221 to S227. Steps S221 to S227 are described in detail below. Step S22 is executed after step S10 is completed.

[0096] Step S221, based on the state data being in the second state, the hoisting unit 11 moves the battery box 02 in the first row of battery holders 13, which has the highest power in the first area, to an empty battery holder 13. Among them, the second state may include the battery box 02 with low power on the battery swap vehicle 03 being located at the first position in the battery swap area, the battery holders 13 in the first row of battery holders 13 in the first area away from the battery swap area being empty, the battery box 02 in the second row of battery holders 13 in the first area away from the battery swap area having the highest power, and the battery box 02 with low power of the previous battery swap vehicle 03 being contained in the second row of rotating seats 122, X≥6. The distance between the plane of symmetry of the first position in the second direction and the plane of symmetry of the first row of battery holders 13 in the second direction is less than the first set distance along the second direction, and the first set distance may be 10cm to 20cm, that is, the first position and the first row of battery holders 13 are in the same row.

[0097] In step S222, the hoisting unit 11 moves the battery box 02 with the highest power in the first row of battery seats 13 to an empty battery seat 13. The hoisting unit 11 moves the battery box 02 with the highest power through the battery exchange channel to the first row of rotating seats 122, thereby reserving a channel for the hoisting unit 11 to move the battery box 02 subsequently to avoid obstruction of movement.

[0098] Step S223, based on the lifting unit 11, the battery box 02 with the highest power is moved through the battery replacement channel to the first 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.

[0099] In step S224, based on the rotation of the rotating base 121 of the rotating unit 12 by 180 degrees around the central axis of the rotating base 121, the hoisting unit 11 moves the battery box 02 with low power in the first row of rotating seats 122 to the vacant battery seat 13 in the first area through the battery exchange channel. The battery box 02 with low power in the first row of rotating seats 122 is preferentially moved to the battery seat 13 in the second row. In this way, when a new battery exchange vehicle 03 needs to exchange batteries, the battery box 02 that is easier to move and has a higher power level can be preferentially selected, thereby improving the battery exchange efficiency.

[0100] Step S225, based on the hoisting unit 11, the battery box 02 with low power in the first row of rotating seats 122 is moved to the idle battery seat 13 in the first area through the battery exchange channel, and the hoisting unit 11 moves the battery box 02 with low power on the battery exchange vehicle 03 to the first row of rotating seats 122.

[0101] Step S226: Based on the hoisting unit 11, the low-power battery box 02 on 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.

[0102] In step S227, 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 with the highest power in the first row of rotating seats 122 to the battery swap vehicle 03. By accurately delivering the high-power battery to the battery swap vehicle 03, the energy supply demand of the battery swap vehicle 03 can be directly met, thereby completing the battery swap operation for the battery swap vehicle 03. At the same time, the higher-power battery can provide the battery swap vehicle 03 with a longer driving range.

[0103] In this embodiment, the status data also includes the number of battery-swapping vehicles 03 in the waiting area. The vehicle battery-swapping method further includes step S40, which includes steps S41 to S43. Steps S41 to S43 are described in detail below. Step S40 is executed after step S30 is completed.

[0104] In step S41, based on the hoisting unit 11 grabbing the battery box 02 in the battery holder 13 in a row away from the battery swapping area in the first area and moving it to the battery swapping vehicle 03 through the battery swapping channel, and there is no battery swapping vehicle 03 in the waiting area, the hoisting unit 11 moves the battery box 02 in the first row of battery holders 13 in the first area close to the battery swapping area to the rotating seat 122. By readjusting the storage position of the battery box 02 when there is no waiting battery swapping vehicle 03, the battery box 02 with higher power is transferred to a position closer to the battery swapping channel, thereby shortening the hoisting path for subsequent battery swapping operations.

[0105] Step S42, based on the hoisting unit 11, the battery box 02 in the first row of battery holders 13 in the first area close to the battery exchange area is moved to the rotating seat 122, and the hoisting unit 11 moves the battery box 02 in the first row of battery holders 13 away from the battery exchange area in the first area to the first row of battery holders 13 in the first area close to the battery exchange area.

[0106] In step S43, the hoisting unit 11 moves the battery box 02 in a row of battery holders 13 in the first area away from the battery swap area to the first row of battery holders 13 in the first area close to the battery swap area. The hoisting unit 11 moves the battery box 02 on the rotating seat 122 to the battery holder 13 in the first area close to the battery swap area. By adjusting the battery box 02 in the battery holder 13, the battery box 02 with a higher charge can be moved to a charging seat closer to the battery swap channel, thereby shortening the movement path of the battery box 02 by the hoisting unit 11, and improving the overall battery swap efficiency after the subsequent battery swap vehicle 03 enters the first area.

[0107] In this embodiment, the vehicle battery replacement method further includes step S24, which includes steps S241 to S242. Steps S241 to S242 are described in detail below. Step S24 is executed after step S10 is completed.

[0108] Step S241, based on the status data being in the third state, the hoisting unit 11 moves the low-power battery box 02 on the battery swap vehicle 03 to the rotating seat 122. Among them, the third state includes that the battery box 02 in a row of battery holders 13 away from the battery swap area in the second area of ​​the set area has the highest power, and the rotating seat 122 is idle, that is, there is no battery box 02 on the rotating seat 122, the first area, the battery swap channel, and the second area are arranged in sequence along the second direction, and X battery holders 13 are arranged in the second area. The X battery holders 13 in the second area are divided into at least two columns along the second direction and divided into two rows along the second direction. By adding battery holders 13 in the second area, the number of battery boxes 02 can be increased, thereby improving the energy storage capacity.

[0109] In step S242, the hoisting unit 11 moves the low-charge battery box 02 on the battery-swapping vehicle 03 to the rotating seat 122. The hoisting unit 11 grabs the battery box 02 in a row of battery seats 13 in the second area away from the battery-swapping area and moves it to the battery-swapping vehicle 03 through the battery-swapping channel. By moving the high-charge battery box 02 in the second area along the battery-swapping channel to the battery-swapping vehicle 03, the battery of the battery-swapping vehicle 03 can be replaced. This ensures that the battery-swapping vehicle 03 can have a higher mileage after the battery replacement.

[0110] In this embodiment, the vehicle battery replacement system is applied to the vehicle battery replacement method, such as Figure 3 、 Figure 4As shown, the vehicle battery replacement system may include a battery replacement component 01, a battery box 02, and a battery replacement vehicle 03.

[0111] The battery exchange component 01 may include a hoisting unit 11, a rotating unit 12, X battery holders 13, a battery exchange area, and a control unit 15. The area projected downward from the moving range of the hoisting unit 11 may include a set area and a battery exchange area. The set area may include a first area and a battery exchange channel, and the first area and the battery exchange channel may be arranged in sequence along the second direction. The battery holder 13 and the rotating unit 12 are arranged in the first area, and the battery holder 13, the rotating unit 12, and the battery exchange area are arranged in sequence along the first direction. The X battery holders 13 are divided into at least two columns along the first direction and into two rows along the second direction, and X ≥ 4. The first direction may be the length direction of the battery holder 13, that is, Figure 2 The left and right directions shown in FIG. 1 and the second direction may be the width direction of the battery holder 13, that is, Figure 2 The up and down directions shown. The battery holders 13 are arranged in a matrix manner to make full use of the space in the battery swap station. The rotating unit 12 may include a rotating base 121 and two rotating bases 122. The rotating base 121 rotates around the central axis of the rotating base 121, and the rotating base 122 is connected to the top of the rotating base 121, and the two rotating bases 122 are arranged at intervals. In the second direction, the distance between the symmetry plane of one rotating base 122 and the symmetry plane of a row of battery holders 13 in the second direction is less than a set value, and the set value can be 10cm to 20cm. The distance between the symmetry plane of another rotating base 122 in the second direction and the symmetry plane of another row of battery holders 13 in the second direction is less than a set value. In this way, the rotating base 122 and the charging base are in the same row as much as possible, which is more conducive to the installation and disassembly of the battery box 02 by the hoisting unit 11. 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, so that when the battery box 02 is detachably connected to the battery holder 13, the battery box 02 is within the area where the battery holder 13 is projected in the direction close to the battery box 02; when the battery box 02 is detachably connected to the rotating seat 122, the battery box 02 is within the area where the rotating seat 122 is projected in the direction close to the battery box 02. The control unit 15 is connected to the hoisting unit 11. The number of battery boxes 02 is the same as the number of battery holders 13, and X battery boxes 02 are detachably connected to any X of the battery holders 13 and the rotating seat 122. The control unit 15 can also obtain the position of the battery box 02 on the battery swap vehicle 03 in the battery swap area, control the moving path and movement of the hoisting unit 11, rotate the rotating unit 12, and obtain the power of the battery box 02 in the battery holder 13.

[0112] A can be the distance between the hanging unit 11 and the battery holder 13 along the third direction, and B can be the height of the battery box 02. The third direction can be the height direction of the battery box 02, that is, Figure 4In the vertical direction shown, B < A allows sufficient space for the hoisting unit 11 to remove and install the battery box 02 and the battery holder 13 in the third direction. A < 2 × B avoids excessive space for the hoisting unit 11 to move in the third direction, thereby reducing the volume of the hoisting unit 11. C is the distance between the battery swap area and any rotating holder 122 along the first direction, and L is the length of the battery box 02. 0 ≤ C < T × L, 1 ≤ T ≤ 1.1. By limiting the distance between the battery swap area and any rotating holder 122 along the first direction, the range of movement of the hoisting unit 11 in the first direction is reduced, thereby reducing the volume of the hoisting unit 11 in the first direction. D is the distance between the second row of battery holders 13 in the first area and the side of the first area away from the battery swap channel. K is the width of the battery box 02. 0 ≤ D < T × K. By limiting the distance between the second row of battery holders 13 and the side of the first area away from the battery swap channel, the range of movement of the hoisting unit 11 in the second direction is reduced, thereby reducing the volume of the hoisting unit 11 in the second direction. E can be the distance between the first row of battery holders 13 in the first area and the side of the battery exchange channel away from the first area, E>K, so that the battery box can pass through the battery exchange channel, thereby quickly exchanging batteries. F can be the minimum distance between the first row of battery holders 13 and the second row of battery holders 13, 0≤F<T×K. By limiting the minimum distance between the first row of battery holders 13 and the second row of battery holders 13, the movement range of the hoisting unit 11 along the second direction is further reduced, thereby reducing the volume of the hoisting unit 11 along the second direction. Finally, by using the battery exchange channel as a moving channel and the rotating unit 12 as a transfer component, the battery exchange vehicle 03 can be replaced, and the moving path of the hoisting unit 11 can be shortened, thereby improving the battery exchange efficiency and reducing the volume of the hoisting unit 11.

[0113] The battery-swap vehicle 03 may include a vehicle body 31 and a mounting base 32. The vehicle body 31 and the mounting base 32 are detachably and electrically connected, and the battery box 02 is detachably and electrically connected to the mounting base 32. The vehicle body 31 can obtain electrical energy from the battery box 02 through the mounting base 32, thereby driving the battery-swap vehicle 03 to travel normally on the road.

[0114] In this embodiment, if Figure 2 As shown, the set area may also include a second area. The first area, the battery exchange channel, and the second area are arranged in sequence along the second direction. X battery holders 13 are arranged in the second area, and the X battery holders 13 in the second area are divided into at least two columns along the second direction and divided into two rows along the second direction. By adding battery holders 13 in the second area, the number of battery boxes 02 can be increased, thereby improving the energy storage capacity.

[0115] Z can be the distance between a row of battery holders 13 in the second area away from the battery swap channel and the side of the second area away from the battery swap channel along the second direction, K can be the width of the battery box 02, 0≤Z<T×K, 1≤T≤1.1. By limiting the distance between a row of battery holders 13 in the second area away from the battery swap channel and the side of the second area away from the battery swap channel along the second direction, the movement path of the hoisting unit 11 along the second direction is reduced, thereby reducing the volume of the hoisting unit 11 along the second direction and improving the battery swap efficiency. Y is the distance between the first row of battery holders 13 and the second row of battery holders 13 in the second area, 0≤Y<T×K. By limiting the distance between the first row of battery holders 13 and the second row of battery holders 13 in the second area, the movement path of the hoisting unit 11 along the second direction can be further reduced, thereby further reducing the volume of the hoisting unit 11 along the second direction and improving the battery swap efficiency. W is the distance between the first row of battery holders 13 in the second area and the side of the battery exchange channel away from the second area, 0≤W<T×K. By limiting the distance between the first row of battery holders 13 in the second area and the side of the battery exchange channel away from the second area, the moving path of the hoisting unit 11 along the second direction can be reduced, thereby reducing the volume of the hoisting unit 11 along the first direction.

[0116] In other embodiments, the battery exchange system may further include a power delivery vehicle 14, which is detachably connected to the battery holder 13. In this way, the battery box 02 components and the battery holder 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. In the second direction, the distance between the symmetry plane of a rotating seat 122 and the symmetry plane of the battery exchange channel in the second direction is less than a set value, and the distance between the symmetry plane of another rotating seat 122 in the second direction and the symmetry plane of the first row of battery holders 13 in the second direction is less than a set value. Therefore, when the battery boxes 02 in the first area and the second area are transferred through the rotating seat 122, the moving path of the hoisting unit 11 can be shorter, thereby improving the battery exchange efficiency. The hoisting unit 11 may include a trolley guide rail 111, a trolley part 112, a trolley guide rail, a trolley body 31, a grabbing part 113, and a supporting part 114. One end of the support portion 114 can be spaced apart from the rotating unit 12 and the battery holder 13 respectively, and the other end can extend away from the battery holder 13 along the third direction. The trolley guide rail 111 can be connected to the end of the support portion 114 away from the battery holder 13, so that the support portion 114 provides support for the trolley guide rail 111. The length direction of the trolley guide rail 111 can be parallel to the first direction. The trolley portion 112 can be slidably connected to the trolley guide rail 111, and the trolley portion 112 can move along the length direction of the trolley guide rail 111. The trolley guide rail can be connected to the trolley portion 112, and the length direction of the trolley guide rail can be parallel to the second direction. The trolley body 31 can be slidably connected to the trolley guide rail, and the trolley body 31 can move along the length direction of the trolley guide rail. The grasping portion 113 can be drive-connected to the trolley body 31, and the trolley body 31 can drive the grasping portion 113 to move along the third direction. This arrangement allows the grabbing portion 113 to be raised and lowered along the third direction to grab the battery box 02 assembly, and then the battery box 02 assembly can be moved by moving the trolley body 31 along the second direction and the trolley portion 112 along the first direction. The set area is the area where the trolley guide rail moves from one end of the trolley guide rail 111 to the other end of the trolley guide rail 111. 1.2*K>E>K, by limiting the distance between the second row of battery holders 13 and the first area away from the battery exchange channel, the movement range of the hoisting unit 11 along the second direction is reduced, thereby reducing the volume of the hoisting unit 11 along the second direction.
