Battery swapping stations and battery swapping methods

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese patent application 202411934148.2, filed on December 26, 2024, entitled “Battery Swapping Station and Battery Swapping Method”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of battery swapping technology, and more specifically, to a battery swapping station and a battery swapping method. Background Technology

[0004] With technological advancements, the battery industry has developed rapidly, and the market share and usage frequency of electric devices are increasing. Electric vehicles, such as electric cars, are gradually appearing in various application scenarios. At the same time, to improve the convenience of electric vehicles, battery swapping stations for rapid battery replacement have emerged in the market.

[0005] Improving the reliability of battery swapping has become an important research direction in the industry. Summary of the Invention

[0006] This application provides a battery swapping station and a battery swapping method, which can reduce the risk of battery device contamination and improve the reliability of battery swapping.

[0007] Firstly, this application provides a battery swapping method, which includes:

[0008] After the vehicle enters the battery swapping station and passes the support device at the first work station, the support device moves from the first work station to the second work station.

[0009] The battery swapping unit at the third station removes the battery pack from the vehicle chassis. The third station is located below the first station.

[0010] The support device moves from the second station to the first station;

[0011] The support device moves again from the first station to the second station, and the battery swapping device moves from the third station to the fourth station, so that the support device separates the battery device and the chassis for a period of time. The second station is located on one side of the first station along the direction from the third station to the fourth station.

[0012] During the process of transferring the battery device removed from the vehicle by the battery swapping unit, the support device can move together with the battery swapping unit to shield it from water droplets, dust and other impurities falling from the chassis. This reduces the amount of impurities falling onto the battery device, lowers the risk of battery device failure and the risk of replacing a failed battery device with a failed one, and improves the reliability of battery swapping.

[0013] In some embodiments, the step of "the battery swapping device at the third station removing the battery device from the chassis of the vehicle" includes: moving the battery swapping device from the fourth station to the third station; and removing the battery device from the chassis of the vehicle.

[0014] In some embodiments, the step of "moving the battery swapping device from the fourth station to the third station" is performed after the step of "moving the support device from the first station to the second station".

[0015] In other embodiments, the steps of "moving the battery swapping device from the fourth station to the third station" and "moving the support device from the first station to the second station" are performed simultaneously for a period of time. The time for the battery swapping device to move coincides at least partially with the time for the support device to move, which helps to optimize the battery swapping cycle and improve battery swapping efficiency.

[0016] In some embodiments, the step of "removing the battery pack from the vehicle chassis by the battery swapping unit at the third station" includes:

[0017] The battery swapping unit at the third workstation begins to lift its connection platform. When the connection platform is lifted to the first preset height, it supports the battery device.

[0018] The docking platform releases the lock between the battery pack and the vehicle chassis;

[0019] The docking platform carrying the battery device descends and stops after descending to the second preset height.

[0020] In some embodiments, in the steps of "removing the battery device from the vehicle chassis by the battery swapping unit at the third station" and "moving the support device from the second station to the first station," the descent of the docking platform and the movement of the support device occur simultaneously for a period of time. The timing of the docking platform's descent partially overlaps with the timing of the support device's movement, which helps optimize the battery swapping cycle and improve swapping efficiency.

[0021] In some embodiments, in the steps of "removing the battery device from the vehicle chassis by the battery swapping device at the third station" and "moving the support device from the second station to the first station," the support device begins to move from the second station when the docking platform descends to a third preset height. This third preset height is higher than the second preset height but lower than the first preset height. This embodiment of the application, by moving the support device only after the docking platform has descended a certain distance, helps reduce the risk of interference between the support device and the battery device, reduces the possibility of damage to the battery device, and improves the reliability of battery swapping.

[0022] In some embodiments, during the steps of "removing the battery device from the vehicle chassis by the battery swapping unit at the third station" and "moving the support device from the second station to the first station," the support device moves to the first station simultaneously with the docking platform descending to a second preset height. The simultaneous arrival of the docking platform and the support device facilitates the execution of subsequent steps, optimizes the battery swapping cycle, and improves battery swapping efficiency.

[0023] In some embodiments, during the step of "the support device moving again from the first station to the second station, and the battery swapping device moving from the third station to the fourth station, so that the support device separates the battery device from the chassis for a period of time," the support device and the battery swapping device begin to move simultaneously. This simultaneous movement allows the support device to effectively shield the battery device from above, reducing the risk of contamination from water droplets, dust, and other impurities.

[0024] In some embodiments, during the step of "the support device moves again from the first station to the second station, and the battery swapping device moves from the third station to the fourth station, so that the support device separates the battery device and the chassis for a period of time," the moving speed of the support device is equal to the moving speed of the battery swapping device in the direction from the third station to the fourth station. The relative position between the support device and the battery device remains fixed, thereby enabling the support device to effectively shield the battery device from above, reducing the risk of water droplets, dust, and other impurities contaminating the battery device.

[0025] In some embodiments, the battery swapping method further includes:

[0026] At the fourth station, the battery swapping unit replaces the battery pack removed from the chassis with another battery pack.

[0027] The battery swapping unit, carrying the replaced battery, moves from the fourth workstation to the third workstation.

[0028] The battery swapping unit installs the replaced battery into the vehicle's chassis;

[0029] The support device moves from the second station to the first station again.

[0030] In some embodiments, after the step of “the battery swapping device installing the replaced battery device onto the chassis of the vehicle”, the battery swapping method further includes: the battery swapping device moving again from the third station to the fourth station.

[0031] In some embodiments, in the steps of "the battery swapping device moving again from the third station to the fourth station" and "the support device moving again from the second station to the first station," the movement of the battery swapping device and the movement of the support device occur simultaneously for a period of time. The time of movement of the battery swapping device and the time of movement of the support device at least partially overlap, which helps to optimize the battery swapping cycle and improve battery swapping efficiency.

[0032] In some embodiments, the step of "the battery swapping device installing the replaced battery device onto the vehicle chassis" includes:

[0033] The battery swapping unit's connection platform began to rise;

[0034] When the docking platform is raised to the first preset height, the battery device supported on the docking platform is locked to the chassis;

[0035] The connecting platform descends and stops after reaching the second preset height.

[0036] In the steps of "installing the replaced battery unit onto the vehicle chassis" and "moving the support device from the second station to the first station again," the descent of the docking platform and the movement of the support device occur simultaneously for a period of time. The time of the support device's movement and the descent of the docking platform at least partially overlap, which helps to optimize the battery swapping cycle and improve battery swapping efficiency.

[0037] In some embodiments, the step of "the battery swapping device carrying the replaced battery device moving from the fourth station to the third station" includes:

[0038] The battery swapping unit, carrying the replaced battery, moves from the fourth workstation to the third workstation.

[0039] The support device moves from the second station to the first station to separate the battery device carried by the battery swapping device from the chassis during the movement of the battery swapping device.

[0040] After the battery swapping device reaches the third station, the support device moves from the first station to the second station again until it reaches the second station.

[0041] During the process of transferring a fully charged battery pack from the battery swapping unit to the vehicle, the support device can move along with the battery swapping unit to shield it from water droplets, dust, and other impurities falling from the chassis. This reduces the amount of impurities falling onto the battery pack, lowers the risk of battery pack failure, and reduces the risk of replacing a failed battery pack with the vehicle, thus improving the reliability of battery swapping.

[0042] Secondly, this application provides a battery swapping station, comprising a support device, a storage device, a battery swapping device, and a control device. The support device is configured to move between a first station and a second station. The storage device is used to store and charge the battery device. The battery swapping device is configured to move between a third station and a fourth station, the third station being located below the first station and pointing in a direction from the third station to the fourth station, and the second station being located to one side of the first station. The battery swapping device is used to remove the battery device from the vehicle chassis or install the battery device onto the chassis at the third station, and to exchange the battery device with the storage device at the fourth station. The control device is used to control the movement of the support device and the battery swapping device. The control device is configured to control the simultaneous movement of the support device and the battery swapping device for a period of time, such that the support device separates the battery device carried by the battery swapping device from the chassis.

[0043] During the battery swapping process, the support device can move along with the battery swapping device to shield it from water droplets, dust and other impurities falling from the chassis. This reduces the amount of impurities falling onto the battery device, lowers the risk of battery device failure and the risk of replacing a failed battery device, and improves the reliability of battery swapping.

[0044] In some embodiments, the third and fourth workstations are arranged along a first direction, and the battery swapping station includes a plurality of support devices arranged along a second direction, wherein the first direction, the second direction, and the vertical direction are perpendicular to each other.

[0045] The battery swapping station is equipped with multiple support devices. The control unit can move the corresponding support device between the first and second workstations based on parameters such as the vehicle's wheelbase, battery specifications, and quantity. By setting up multiple support devices, battery swapping can be performed on vehicles of different models, ensuring high compatibility.

[0046] In some embodiments, at least two support devices have different dimensions along the second direction. Embodiments of this application are compatible with at least three different vehicle models.

[0047] In some embodiments, the battery swapping device includes a plurality of docking platforms arranged along a second direction, which are used for attaching and detaching battery devices. The plurality of docking platforms are configured to lift and lower independently of each other; each docking platform corresponds one-to-one with a plurality of support devices. For different vehicle models, the support devices that move to the second station during the battery swapping process are also different. Since the plurality of docking platforms can lift and lower independently, when a certain support device moves to the second station, the battery swapping device can lift the docking platform corresponding to that support device to complete the battery swap. For support devices that remain at the first station, the battery swapping device may not lift the docking platform corresponding to that support device, thereby reducing the risk of interference.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0060] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0061] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0062] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0063] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0064] In this application, "multiple" means two or more (including two).

[0065] In the embodiments of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering.

[0066] With the development of new energy technologies, more and more devices are using battery devices. Taking vehicles as an example, when a vehicle's battery is depleted, it is usually replenished by connecting to a charging device. Charging takes a long time, affecting the user experience. Compared to charging, replacing the battery device can replenish the energy much faster.

[0067] In related technologies, battery swapping stations typically feature a recessed battery swapping channel within which the battery swapping device moves. A support device is usually placed at the opening on the upper side of the swapping channel to support the vehicle as it passes through. After the vehicle has passed, the support device opens the opening of the swapping channel, allowing the battery swapping device to install or remove the battery pack through the opening.

[0068] After the battery is removed from the battery swapping unit, it needs to be transported to the charging compartment of the battery swapping station for charging. However, during the transportation of the battery, water droplets or dust from the vehicle chassis may fall onto the battery, posing a risk of contamination of the battery interface, affecting the performance and lifespan of the battery, and potentially leading to battery swapping failure.

[0069] In view of this, the present application provides a battery swapping station and a battery swapping method, which uses a movable support device to shield the battery device during the transfer of the battery device by the battery swapping device, thereby reducing the amount of impurities falling onto the battery device, reducing the risk of battery device failure, and improving the reliability of battery swapping.

[0070] The battery swapping station and method disclosed in this application can be used, but are not limited to, for swapping vehicle batteries. The vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended vehicles, etc.

[0071] Figure 1 is a schematic diagram of a battery swapping station provided in some embodiments of this application, and Figure 2 is another schematic diagram of a battery swapping station provided in some embodiments of this application.

[0072] Referring to Figures 1 and 2, some embodiments of this application provide a battery swapping station, which includes a storage device 1 and a battery swapping device 2. The storage device 1 can be used to store and charge the battery device 8. The battery swapping device 2 can be used to remove the battery device 8 from the vehicle 9 and to install the battery device 8 stored in the storage device 1 onto the chassis 91 of the vehicle 9.

[0073] As an example, battery swapping stations can replace the battery devices of electric heavy-duty trucks, electric light-duty trucks, electric passenger cars, or other electric vehicles.

[0074] The battery swapping device 2 can be used to replace the battery device 8 of the vehicle 9.

[0075] As an example, the battery swapping station can replace the battery device 8 according to the following steps: I) The battery swapping device 2 can move to the underside of the vehicle 9 and remove the depleted battery device 8 from the chassis 91 of the vehicle 9; II) The battery swapping device 2 transfers the depleted battery device 8 to the storage device 1 for charging and receives the fully charged battery device 8 from the storage device 1; III) The battery swapping device 2 moves the fully charged battery device 8 to the underside of the vehicle 9 and installs the fully charged battery device 8 onto the chassis 91.

[0076] In some embodiments, the battery swapping device 2 includes an Automated Guided Vehicle (AGV).

[0077] In some embodiments, the battery swapping station includes a battery swapping platform 3, which is used to carry the vehicle 9.

[0078] The battery swapping platform 3 is used to place the vehicle 9; after the vehicle 9 is placed on the battery swapping platform 3, the battery device 8 of the vehicle 9 can be replaced. The battery swapping platform 3 can be the ground or a support platform placed on the ground, etc.

[0079] As an example, the battery swapping platform 3 can be a fixed platform or a lifting platform. For example, the battery swapping platform 3 can lift the vehicle 9 placed on it.

[0080] In some embodiments, the storage device 1 includes a plurality of storage slots 11, each storage slot 11 being used to store the battery device 8 and to charge the battery device 8.

[0081] Storage compartment 11 of storage device 1 can serve both to store battery device 8 and to charge battery device 8. As an example, battery device 8 removed from vehicle 9 can be stored in storage compartment 11, and storage compartment 11 can charge battery device 8; a fully charged battery device 8 located in another storage compartment 11 can be installed on chassis 91 of vehicle 9 to complete battery swapping.

[0082] One storage location 11 can store one battery device 8 or multiple battery devices 8. Optionally, one storage location 11 can store one battery device 8.

[0083] In some embodiments, the battery swapping station is provided with a battery swapping channel 10. The battery swapping device 2 is disposed in the battery swapping channel 10 and is movable within the battery swapping channel 10.

[0084] In some embodiments, the battery swapping channel 10 includes a trench that is recessed relative to the ground.

[0085] In some embodiments, the battery swapping channel 10 extends along a first direction X, and the battery swapping device 2 is movable within the battery swapping channel 10 along the first direction X. Optionally, the first direction X is perpendicular to the vertical direction Z.

[0086] In some embodiments, the upper side of the battery swapping channel 10 has an opening.

[0087] In some embodiments, the battery swapping station includes a support device 5. The support device 5 is used to support the vehicle 9. Exemplarily, the vehicle 9 can pass over the support device 5 when entering the battery swapping station.

[0088] There can be one or more support devices 5.

[0089] In some embodiments, the support device 5 is disposed in the battery swapping channel 10. The support device 5 can support the vehicle 9 when the vehicle 9 passes through the battery swapping channel 10.

[0090] For example, when vehicle 9 enters the battery swapping station, the front wheels 92 of vehicle 9 can cross the battery swapping channel 10 through the support device 5; after the battery swapping is completed, the rear wheels 93 of vehicle 9 can cross the battery swapping channel 10 through the support device 5.

[0091] In some embodiments, one end of the battery swapping channel 10 extends to the support device 5, and the other end extends to the storage device 1.

[0092] In some embodiments, the support device 5 may cover at least a portion of the opening of the power swapping channel 10.

[0093] In some embodiments, the battery swapping station further includes a transfer device 6 for transferring the battery device 8 between the storage device 1 and the battery swapping device 2.

[0094] The transfer device 6 can transfer the battery device 8 on the battery swapping device 2 to the storage device 1, or transfer the battery device 8 stored in the storage device 1 to the battery swapping device 2.

[0095] The structure of the transfer device 6 can be varied. For example, the transfer device 6 may include a robot, a palletizer, or other structures.

[0096] In some embodiments, the battery swapping station further includes a buffer device 7, which includes a plurality of buffer bits 71, each buffer bit 71 for storing a battery device 8. The plurality of buffer bits 71 of the buffer device 7 are used for transferring the battery device 8 between the transfer device 6 and the battery swapping device 2, and for transferring the battery device 8 between the transfer device 6 and the storage device 1.

[0097] For example, the battery swapping device 2 can place the depleted battery device 8 removed from the vehicle 9 into a buffer position 71, and then the battery swapping device 2 can remove the fully charged battery device 8 stored in another buffer position 71 and install the fully charged battery device 8 into the vehicle 9; the transfer device 6 can remove the depleted battery device 8 and transfer it to a storage position 11 for charging, and then the transfer device 6 can remove the fully charged battery device 8 stored in another storage position 11 and place the fully charged battery device 8 into a buffer position 71; the fully charged battery device 8 can be used for the next battery swap of the vehicle 9.

[0098] By setting multiple buffer bits 71 in this embodiment, the time for the transfer device 6 to transfer the battery device 8 and the time for the battery swapping device 2 to install and remove the battery device 8 can partially overlap, which is beneficial to optimize the battery swapping cycle and improve the battery swapping efficiency.

[0099] In some embodiments, a plurality of cache bits 71 are arranged along the second direction Y.

[0100] In some embodiments, the battery swapping station includes a control device 4, which is used at least to control the operation of the battery swapping device 2 and the support device 5. Exemplarily, the control device 4 is signal-connected to the battery swapping device 2 and to the support device 5. Optionally, the control device 4 can be connected to the battery swapping device 2 via a wiring harness or via a wireless signal; the control device 4 can also be connected to the support device 5 via a wiring harness or via a wireless signal.

[0101] In some embodiments, the battery swapping station includes a support device 5, a storage device 1, a battery swapping device 2, and a control device 4. The support device 5 is configured to move between a first station P1 and a second station P2. The storage device 1 is used to store and charge the battery device 8. The battery swapping device 2 is configured to move between a third station P3 and a fourth station P4. The third station P3 is located below the first station P1, pointing in a direction from the third station P3 to the fourth station P4. The second station P2 is located to one side of the first station P1. The battery swapping device 2 is used to remove the battery device 8 from the chassis 91 of the vehicle 9 or install the battery device 8 onto the chassis 91 at the third station P3. The battery swapping device 2 is used to exchange the battery device 8 with the storage device 1 at the fourth station P4. The control device 4 is used to control the movement of the support device 5 and the battery swapping device 2. The control device 4 is configured to control the simultaneous movement of the support device 5 and the battery swapping device 2 for a period of time, such that the support device 5 separates the battery device 8 carried by the battery swapping device 2 from the chassis 91.

[0102] The support device 5 at the first work station can be used to support the vehicle 9 when it passes by.

[0103] There can be one or more support devices 5.

[0104] In the vertical direction Z, the height of the first station P1 and the height of the second station P2 can be the same or different. In some examples, the height of the first station P1 and the height of the second station P2 are the same, and the first station P1 and the second station P2 are set along the first direction X, and the support device 5 can translate along the first direction X. In other examples, the second station P2 may be slightly lower than the first station P1. For example, the movement of the support device 5 may be a combination of translation along the first direction X and lifting along the vertical direction Z.

[0105] For example, the support device 5 moves from the first station P1 to the second station P2, and the stroke of the support device 5 in the first direction X can be greater than, equal to, or less than the dimension of the support device 5 along the first direction X. Optionally, the stroke of the support device 5 in the first direction X is greater than the dimension of the battery device 8 along the first direction X.

[0106] When the support device 5 is at the first station P1, it can support the vehicle 9 passing over it to reduce the wheels of the vehicle 9 from sinking into the space under the support device 5 (e.g., the battery swapping channel 10).

[0107] For example, after vehicle 9 enters the battery swapping station, the front wheels 92 of vehicle 9 cross the battery swapping channel 10 via the support device 5 at the first work station P1; when vehicle 9 reaches the target position, it stops, for example, when the battery device 8 of vehicle 9 moves above the support device 5, vehicle 9 can stop.

[0108] When the support device 5 moves to the second station P2, it can avoid the battery swapping device 2 below, so that the battery swapping device 2 can be installed and removed from the battery device 8.

[0109] In the vertical direction Z, the height of the third station P3 and the height of the fourth station P4 can be the same or different. In some examples, the height of the third station P3 and the height of the fourth station P4 are the same, and the third station P3 and the fourth station P4 are set along the first direction X, and the battery swapping device 2 can be translated along the first direction X.

[0110] The support device 5 moves from the first station P1 to the second station P2, and the travel distance of the support device 5 in the first direction X is L1; the battery swapping device 2 moves from the third station P3 to the fourth station P4, and the travel distance of the battery swapping device 2 in the first direction X is L2. L2 can be greater than, equal to or less than L1. Optionally, L2 is greater than L1.

[0111] "The third station P3 is located below the first station P1" can mean that the battery swapping device 2 located at the third station P3 is located below the support device 5 located at the first station P1.

[0112] As an example, in the first direction X, the second station P2 is located on the side of the first station P1 that is close to the storage device 1, and the fourth station P4 is located on the side of the third station P3 that is close to the storage device 1.

[0113] Battery swapping device 2 can directly exchange battery device 8 with storage device 1 at the fourth station P4, or it can indirectly exchange battery device 8 with storage device 1 through other devices. For example, battery swapping device 2 exchanges battery device 8 with storage device 1 through buffer device 7 and transfer device 6.

[0114] For a period of time, the control device 4 controls the support device 5 and the power swapping device 2 to move simultaneously. The movement of the support device 5 can be between the first station P1 and the second station P2, and the movement of the power swapping device 2 can be between the third station P3 and the fourth station P4.

[0115] For example, during this period, the moving speed of the support device 5 along the first direction X can be the same as or different from the moving speed of the battery swapping device 2 along the first direction X.

[0116] For example, the battery device 8 carried by the battery swapping device 2 can be a battery device 8 removed from the chassis 91 by the battery swapping device 2, or it can be a fully charged battery device 8 taken from the storage device 1.

[0117] In some examples, the support device 5 moves toward the second station P2 and the battery swapping device 2 moves toward the fourth station P4 over a period of time; in other examples, the support device 5 moves toward the first station P1 and the battery swapping device 2 moves toward the third station P3 over a period of time.

[0118] In this embodiment of the application, during the process of the battery swapping device 2 transferring the battery device 8, the support device 5 can move together with the battery swapping device 2, thereby blocking water droplets, dust and other impurities falling from the chassis 91, thereby reducing the impurities falling onto the battery device 8, reducing the risk of battery device 8 failure and the risk of replacing the failed battery device 8 with the vehicle 9, and improving the reliability of battery swapping.

[0119] In some embodiments, the support device 5 may include a support plate.

[0120] In some embodiments, the support device 5 is supported by the ground below.

[0121] In some embodiments, in the first direction X, the size of the support device 5 is larger than the size of the battery device 8.

[0122] In some embodiments, in the vertical direction Z, the support device 5 at the first station P1 completely covers the battery device 8 carried on the battery swapping device 2 at the third station P3.

[0123] In some embodiments, the battery device 8 has an interface 81 on its upper side. During the process of the battery swapping device 2 carrying the battery device 8 removed from the chassis 91 toward the fourth station P4, the support device 5 can separate the interface 81 from the chassis 91 to reduce the risk of water droplets or other impurities falling onto the interface 81.

[0124] In some embodiments, interface 81 includes an electrical interface and a heat exchange pipeline interface.

[0125] In some embodiments, the battery swapping station also includes a cleaning device (not shown), through which the vehicle 9 can pass before driving over the support device 5. The cleaning device washes the vehicle body, reducing impurities adhering to it. Liquids remaining during the cleaning process, such as water, may flow to the edge of the chassis 91 under gravity. The support device 5 of this application can shield the battery swapping process from liquid dripping from the chassis 91, reducing the risk of liquid contamination of the battery device 8's interface 81.

[0126] In some embodiments, the support device 5 can be used to separate the chassis 91 from the battery device 8 carried on the battery swapping device 2 along the first direction X near the edge of the storage device 1.

[0127] In some embodiments, the battery swapping station further includes a drive device (not shown), which is connected to the support device 5 and is used to drive the support device 5 to move between the first station P1 and the second station P2.

[0128] In some embodiments, the drive device may be disposed on the side wall of the battery swapping channel 10 along the second direction Y, wherein the first direction X, the second direction Y, and the vertical direction Z are perpendicular to each other. Disposing the drive device on the side wall reduces the risk of interference between the drive device and the battery swapping device 2.

[0129] As an example, the drive unit may include a gear, a rack, and a motor. The motor may be fixed to the lower side of the support device 5, the rack may be fixed to the side wall of the power exchange channel 10, and the motor is connected to the gear. The motor can drive the gear to rotate, so that the gear travels along the extension direction of the rack. The rack may extend along a first direction X.

[0130] Of course, the drive unit can also have other structures. For example, the drive unit may include a cylinder.

[0131] Figure 3 is a simplified schematic diagram of a battery swapping station provided in some other embodiments of this application; Figure 4 is a schematic diagram of a battery swapping station provided in some embodiments of this application during the battery swapping process; Figure 5 is another schematic diagram of a battery swapping station provided in some embodiments of this application during the battery swapping process; Figure 6 is yet another schematic diagram of a battery swapping station provided in some embodiments of this application during the battery swapping process.

[0132] Referring to Figures 1 to 6, the battery swapping station includes multiple support devices 5 arranged along the second direction Y, and the first direction X, the second direction Y and the vertical direction Z are perpendicular to each other.

[0133] As an example, the support device 5 may be 2, 3, 4, 5 or more.

[0134] The dimensions of the multiple support devices 5 along the second direction Y can be the same or different.

[0135] Each support device 5 is provided with a first station P1 and a second station P2. For example, the first stations P1 of the multiple support devices 5 are arranged along the second direction Y, and the second stations P2 of the multiple support devices 5 are arranged along the second direction Y.

[0136] For different types of vehicles 9, the wheelbase of vehicle 9 may be different, and the number of battery devices 8 may also be different.

[0137] For vehicles with a longer wheelbase, the distance between the front and rear wheels is greater, and the size and number of battery packs may also be larger. Battery swapping stations need to be compatible with vehicles with longer wheelbases. If a single support device is used, the support device needs to be larger in the second direction, making it difficult for swapping stations to handle vehicles with shorter wheelbases. Specifically, for vehicles with shorter wheelbases, the distance between the front and rear wheels is smaller, making it difficult for the front wheels to cross the support device.

[0138] Conversely, if the battery swapping station is designed for vehicles with shorter wheelbases, the support device needs to be smaller in the second direction. This would make it difficult for the station to swap batteries for vehicles with longer wheelbases. Specifically, for vehicles with longer wheelbases, the number and size of their battery packs are also larger. Due to the smaller size of the support device, it would be difficult for the battery swapping unit to install or remove the battery packs when the support device is moved to the second station.

[0139] The battery swapping station in this embodiment is equipped with multiple support devices 5. The control device 4 can control the corresponding support device 5 to move between the first station P1 and the second station P2 according to parameters such as the wheelbase of the vehicle 9 and the specifications and quantity of the battery device 8. By setting multiple support devices 5, this embodiment can perform battery swapping for vehicles 9 of different models, achieving high compatibility.

[0140] In some embodiments, the control device 4 can control the independent movement of each support device 5. For example, each support device 5 is provided with a corresponding drive device.

[0141] In some embodiments, at least two support devices 5 have different dimensions along the second direction Y.

[0142] The embodiments of this application are compatible with at least three different vehicle models, which helps to improve the compatibility of battery swapping stations.

[0143] For example, there are two support devices 5.

[0144] In some embodiments, the dimension of one support device 5 along the second direction Y can be 1.5 to 5 times, optionally 2 or 3 times, the dimension of the other support device 5 along the second direction Y.

[0145] In some embodiments, the battery swapping device 2 includes a docking platform 21 for attaching and detaching the battery device 8. The docking platform 21 is configured to be liftable.

[0146] When the support device 5 is in the second position P2, the connecting platform 21 can rise above the battery swapping channel 10 to support the battery device 8 and release the lock between the battery device 8 and the chassis 91. Then, the connecting platform 21 descends to allow the battery device 8 to enter the battery swapping channel 10.

[0147] In some embodiments, the battery swapping device 2 includes a plurality of connection platforms 21 arranged along a second direction Y. The plurality of connection platforms 21 are configured to lift and lower independently of each other. The plurality of connection platforms 21 are provided in a one-to-one correspondence with a plurality of support devices 5.

[0148] The support device 5 that moves to the second station P2 during the battery swapping process varies depending on the vehicle model. Multiple connection platforms 21 can be raised and lowered independently. When a support device 5 moves to the second station P2, the battery swapping device 2 can lift the connection platform 21 corresponding to that support device 5 to complete the battery swap. For support devices 5 that remain at the first station P1, the battery swapping device 2 may not need to lift the connection platform 21 corresponding to that support device 5, thereby reducing the risk of interference.

[0149] In some embodiments, during the process of the battery swapping device 2 transferring the battery device 8, the control device 4 can control the movement of the support device 5 corresponding to the docking platform 21 carrying the battery device 8, so as to block the battery device 8 from above.

[0150] In some embodiments, referring to Figures 3 to 5, when a vehicle 9 with a large wheelbase or a large number of battery devices 8 enters the battery swapping station, the front wheels 92 of the vehicle 9 can cross the battery swapping channel 10 through multiple support devices 5.

[0151] When the battery device 8 of vehicle 9 moves to the upper side of the support device 5, multiple support devices 5 move to the second work station P2, and multiple docking platforms 21 of battery swapping device 2 lift and remove the battery device 8 of vehicle 9.

[0152] When the battery swapping device 2 transfers the battery device 8 within the battery swapping channel 10, the control device 4 controls multiple support devices 5 and the battery swapping device 2 to move simultaneously, so that the multiple support devices 5 can block the battery device 8 from above.

[0153] For example, vehicle 9 may be provided with three battery devices 8 arranged along the second direction Y, battery swapping station is provided with two support devices 5, and battery swapping device 2 is provided with two docking platforms 21.

[0154] The two support devices 5 have different dimensions along the second direction Y. The larger support device 5 can be defined as the first support device 5a, and the smaller support device 5 can be defined as the second support device 5b. When the vehicle 9 moves into place, the two battery devices 8 are located above the first support device 5a, and the remaining battery device 8 is located above the second support device 5b.

[0155] After the front wheels 92 of vehicle 9 pass the battery swapping channel 10, the first support device 5a and the second support device 5b can move to the second station P2; the two docking platforms 21 of the battery swapping device 2 are lifted, one docking platform 21 disassembles the two battery devices 8 corresponding to the first support device 5a, and the other docking platform 21 disassembles the one battery device 8 corresponding to the second support device 5b.

[0156] After the docking platform 21 is lowered into position and the first support device 5a and the second support device 5b are both moved to the first work station P1, the control device 4 controls the battery swapping device 2, the first support device 5a and the second support device 5b to move along the first direction X, so that the first support device 5a and the second support device 5b separate the chassis 91 from the three battery devices 8 for a period of time.

[0157] In some embodiments, referring to Figures 3 and 6, when a vehicle 9 with a small wheelbase or a small number of battery devices 8 enters a battery swapping station, the front wheels 92 of the vehicle 9 can be supported by a support device 5.

[0158] In some examples, vehicle 9 may be provided with two battery units 8 arranged along the second direction Y, battery swapping station is provided with two support units 5, and battery swapping unit 2 is provided with two docking platforms 21.

[0159] The two support devices 5 have different dimensions along the second direction Y. The larger support device 5 can be defined as the first support device 5a, and the smaller support device 5 can be defined as the second support device 5b. Because the wheelbase of the vehicle 9 is small, when the vehicle 9 moves into place, the front wheel 92 of the vehicle 9 can be supported on the second support device 5b, and the two battery devices 8 are located above the first support device 5a.

[0160] After the front wheels 92 of vehicle 9 reach the second support device 5b, the second support device 5b remains at the first work station P1. The first support device 5a moves to the second work station P2; the docking platform 21 of the battery swapping device 2 corresponding to the first support device 5a is lifted and the two battery devices 8 are removed.

[0161] After the docking platform 21 is lowered into position and the first support device 5a moves to the first work station P1, the control device 4 controls the battery swapping device 2 and the first support device 5a to move along the first direction X, so that the first support device 5a separates the chassis 91 from the two battery devices 8 for a period of time.

[0162] In other examples, vehicle 9 may be equipped with a battery device 8. After the front wheels 92 of vehicle 9 pass through the battery swapping channel 10 via the first support device 5a and the second support device 5b, the rear wheels 93 of vehicle 9 may be supported by the first support device 5a. The first support device 5a remains at the first station P1. The second support device 5b moves to the second station P2; the docking platform 21 of battery swapping device 2 corresponding to the second support device 5b is lifted and the battery device 8 is removed.

[0163] After the docking platform 21 is lowered into position and the second support device 5b moves to the first work station P1, the control device 4 controls the battery swapping device 2 and the second support device 5b to move along the first direction X, so that the second support device 5b separates the chassis 91 from the battery device 8 for a period of time.

[0164] Figure 7 is a flowchart illustrating a battery swapping method provided in some embodiments of this application; Figures 8 to 18 are schematic diagrams illustrating different stages of a battery swapping station provided in some embodiments of this application during the battery swapping process. In the figures, arrow M1 indicates the direction of movement of the support device, and arrow M2 indicates the direction of movement of the battery swapping device.

[0165] Referring to Figures 1, 7 to 18, embodiments of this application provide a battery swapping method, which includes:

[0166] S01. After vehicle 9 enters the battery swapping station and passes the support device 5 at the first work station P1, the support device 5 moves from the first work station P1 to the second work station P2.

[0167] S02, The battery swapping device 2 at the third station P3 removes the battery device 8 from the chassis 91 of the vehicle 9. The third station P3 is located below the first station P1.

[0168] S03, the support device 5 moves from the second station P2 to the first station P1;

[0169] S04, the support device 5 moves again from the first station P1 to the second station P2, and the battery swapping device 2 moves from the third station P3 to the fourth station P4, so that the support device 5 separates the battery device 8 and the chassis 91 for a period of time. The second station P2 is located on one side of the first station P1 along the direction from the third station P3 to the fourth station P4.

[0170] As an example, in step S01, the support device 5 can be used to support the vehicle 9 when the front wheels 92 of the vehicle 9 pass through the battery swapping channel 10.

[0171] In step S02, the battery swapping device 2 can be in the third station P3, or it can be moved from other positions to the third station P3.

[0172] In some examples, step S01 and step S02 can be performed after the support device 5 moves from the first station P1 to the second station P2. Alternatively, in steps S01 and S02, the operation of the support device 5 and the operation of the power swapping device 2 can be performed simultaneously for a period of time, as long as the power swapping device 2 and the support device 5 do not interfere with each other.

[0173] In some examples, step S02 can be performed first, followed by step S03. Alternatively, in steps S02 and S03, the operation of the support device 5 and the operation of the battery swapping device 2 can be performed simultaneously for a period of time, as long as the battery swapping device 2 and the support device 5 do not interfere with each other.

[0174] In step S04, the support device 5 and the power swapping device 2 can start moving simultaneously, or the support device 5 can start moving first, and the power swapping device 2 can start moving after the support device 5 has moved a certain distance, or the power swapping device 2 can start moving first, and the support device 5 can start moving after the power swapping device 2 has moved a certain distance.

[0175] As an example, in step S04, the moving speeds of the support device 5 and the battery swapping device 2 along the first direction X can be the same or different.

[0176] In step S04, the time when the support device 5 moves to the second station P2 can be the same as or different from the time when the power exchange device 2 moves to the fourth station P4.

[0177] During the process of transferring the battery device 8 removed from the vehicle 9 by the battery swapping device 2, the support device 5 can move together with the battery swapping device 2 to block water droplets, dust and other impurities falling from the chassis 91, thereby reducing the impurities falling onto the battery device 8, reducing the risk of battery device 8 failure and the risk of replacing the failed battery device 8 with the vehicle 9, and improving the reliability of battery swapping.

[0178] In some embodiments, the battery swapping method further includes:

[0179] S05, the battery swapping device 2 replaces the battery device 8 removed from the chassis 91 with another battery device 8 at the fourth station P4.

[0180] S06. The battery swapping device 2, carrying the replaced battery device 8, moves from the fourth station P4 to the third station P3.

[0181] S07, The battery swapping device 2 installs the replaced battery device 8 onto the chassis 91 of the vehicle 9;

[0182] S08, the support device 5 moves again from the second station P2 to the first station P1.

[0183] As an example, in step S05, the battery swapping device 2 places the battery device 8 removed from the chassis 91 into a buffer position 71, and then removes a fully charged battery device 8 from another buffer position 71.

[0184] During step S06, the support device 5 may or may not move.

[0185] In some examples, step S07 can be executed first, followed by step S08. Alternatively, in steps S07 and S08, the operation of the support device 5 and the operation of the battery swapping device 2 can be performed simultaneously for a period of time, as long as the battery swapping device 2 and the support device 5 do not interfere with each other.

[0186] In some embodiments, after step S08, vehicle 9 may pass through support device 5 and drive out of the battery swapping station. As an example, the rear wheels 93 of vehicle 9 cross the battery swapping channel 10 via support device 5, thereby driving out of the battery swapping station.

[0187] In some embodiments, step S02 includes:

[0188] S02a: The battery swapping device 2 moves from the fourth station P4 to the third station P3;

[0189] S02b: The battery swapping device 2 removes the battery device 8 from the chassis 91 of the vehicle 9.

[0190] After each battery swapping cycle, the battery swapping device 2 can be stored at the fourth station P4. At the start of a new battery swapping cycle, the battery swapping device 2 can be moved from the fourth station P4 to the third station P3.

[0191] In steps S01 and S02a, the movement of the support device 5 and the movement of the battery swapping device 2 are not sequential. In some examples, the battery swapping device 2 may begin moving from the fourth station P4 to the third station P3 after the support device 5 has moved to the second station P2; in other examples, the support device 5 may begin moving from the first station P1 to the second station P2 after the battery swapping device 2 has moved from the fourth station P4 to the third station P3. In still other examples, the movement of the support device 5 and the movement of the battery swapping device 2 may be performed simultaneously in steps S01 and S02a.

[0192] In some embodiments, step S02a is executed after step S01, that is, step S01 is executed first, and then step S02a is executed.

[0193] In other embodiments, in steps S02a and S01, the movement of the battery swapping device 2 and the movement of the supporting device 5 occur simultaneously for a period of time.

[0194] The time when the battery swapping device 2 starts moving can be the same as or different from the time when the support device 5 starts moving; the time when the battery swapping device 2 reaches the second station P2 can be the same as or different from the time when the support device 5 reaches the third station P3.

[0195] The moving speed of the support device 5 in the first direction X can be the same as or different from the moving speed of the battery swapping device 2 in the first direction X.

[0196] In this embodiment, the time for the battery swapping device 2 to move coincides at least partially with the time for the support device 5 to move, which helps to optimize the battery swapping cycle and improve battery swapping efficiency.

[0197] In some embodiments, in steps S02a and S01, the time when the battery swapping device 2 starts moving is the same as the time when the support device 5 starts moving, and the time when the battery swapping device 2 reaches the second station P2 is the same as the time when the support device 5 reaches the third station P3.

[0198] In some embodiments, step S02 includes:

[0199] S02c, the connection platform 21 of the battery swapping device 2 in the third work station P3 begins to rise. When the connection platform 21 is raised to the first preset height H1, the connection platform 21 supports the battery device 8.

[0200] S02d, the docking platform 21 releases the lock between the battery device 8 and the chassis 91 of the vehicle 9;

[0201] S02e, the docking platform 21 carrying the battery device 8 descends, and the docking platform 21 stops after descending to the second preset height H2.

[0202] As an example, step S02b includes steps S02c, S02d, and S02e.

[0203] The first preset height H1 is higher than the second preset height H2. As an example, in step S02c, the docking platform 21 is raised from the second preset height H2.

[0204] As an example, the first preset height H1 is higher than the support device 5 at the first work station P1, and the second preset height H2 is lower than the support device 5 at the first work station P1.

[0205] In some examples, step S01 can be executed first, followed by step S02c. In other examples, in steps S01 and S02c, the lifting of the docking platform 21 and the movement of the support device 5 occur simultaneously for a period of time, as long as the docking platform 21 does not interfere with the support device 5 during the lifting process; for example, after the docking platform 21 is lifted to a short height, the support device 5 moves to the second work station P2.

[0206] In some examples, step S02e can be executed first, followed by step S03. In other examples, in steps S03 and S02e, the descent of the docking platform 21 and the movement of the support device 5 toward the first workstation P1 occur simultaneously for a period of time, as long as the docking platform 21 does not interfere with the support device 5 during the descent.

[0207] In some embodiments, referring to Figures 9 to 12, in steps S02 and S03, the descent of the docking platform 21 and the movement of the support device 5 occur simultaneously over a period of time.

[0208] For example, in steps S03 and S02e, the moment when the docking platform 21 begins to descend can be the same as or different from the moment when the support device 5 begins to move from the second station P2.

[0209] In this embodiment, the time for the docking platform 21 to descend partially coincides with the time for the support device 5 to move, which helps to optimize the battery swapping cycle and improve battery swapping efficiency.

[0210] In some embodiments, in steps S02 and S03, when the docking platform 21 descends to the third preset height H3, the support device 5 starts to move from the second work station P2, wherein the third preset height H3 is higher than the second preset height H2 and lower than the first preset height H1.

[0211] When the connecting platform 21 is at the third preset height H3, the upper surface of the connecting platform 21 used to support the battery device 8 can be higher than the upper surface of the support device 5, lower than the upper surface of the support device 5, or flush with the upper surface of the support device 5.

[0212] In this embodiment, the support device 5 is moved only after the docking platform 21 has descended a certain distance. This helps to reduce the risk of interference between the support device 5 and the battery device 8, reduce the possibility of the battery device 8 being damaged, and improve the reliability of battery swapping.

[0213] In some embodiments, during steps S02 and S03, while the docking platform 21 descends to the second preset height H2, the support device 5 moves to the first workstation P1.

[0214] As an example, when the support device 5 is at the first work position P1 and the connecting platform 21 is at the second preset height H2, the distance between the support device 5 and the connecting platform 21 is greater than the height of the battery device 8.

[0215] The simultaneous arrival of the connection platform 21 and the support device 5 facilitates the execution of subsequent steps (such as step S04), optimizes the battery swapping cycle, and improves battery swapping efficiency.

[0216] In some embodiments, referring to Figures 13 and 14, in step S04, the support device 5 and the battery swapping device 2 begin to move simultaneously. Exemplarily, at the same time, the support device 5 begins to move from the first station P1 toward the second station P2, and the battery swapping device 2 begins to move from the third station P3 toward the fourth station P4.

[0217] In this embodiment, the support device 5 and the battery swapping device 2 start moving simultaneously so that the support device 5 can effectively shield the battery device 8 from above, reducing the risk of water droplets, dust and other impurities contaminating the battery device 8.

[0218] In some embodiments, in step S04, the moving speed of the support device 5 is equal to the moving speed of the battery swapping device 2 in the direction from the third station P3 to the fourth station P4.

[0219] In this embodiment, the relative position between the support device 5 and the battery device 8 can be kept fixed in the first direction X, so that the support device 5 can effectively shield the battery device 8 from the top, reducing the risk of water droplets, dust and other impurities contaminating the battery device 8.

[0220] In some embodiments, in the first direction X, the travel distance of the support device 5 from the first station P1 to the second station P2 is less than the travel distance of the battery swapping device 2 from the third station P3 to the fourth station P4.

[0221] In some embodiments, in step S04, the support device 5 stops after reaching the second station P2. When the support device 5 reaches the second station P2, the battery swapping device 2 has not yet reached the fourth station P4, and the battery swapping device 2 continues to move until it reaches the second station P2 and then stops.

[0222] In some embodiments, step S05 includes:

[0223] S05a: At the fourth station P4, the docking platform 21 of the battery swapping device 2 lifts the battery device 8 removed from the chassis 91 and places the battery device 8 in an empty buffer position 71 of the buffer device 7, and then the docking platform 21 lowers.

[0224] S05b: The multiple cache positions 71 of the cache device 7 move along the second direction Y, and another cache position 71 storing another battery device 8 moves to above the docking platform 21;

[0225] S05c: The docking platform 21 rises and supports another battery device 8, and then the docking platform 21 drives the other battery device 8 to fall so that the other battery device 8 is removed from the buffer position 71.

[0226] In some embodiments, step S07 includes:

[0227] S07a: The connection platform 21 of the battery swapping device 2 begins to rise;

[0228] S07b: When the docking platform 21 is raised to the first preset height H1, the battery device 8 supported on the docking platform 21 is locked to the chassis 91;

[0229] S07c: The connecting platform 21 descends and stops after descending to the second preset height H2.

[0230] In some examples, step S07c can be performed first, followed by step S08. Alternatively, in steps S07c and S08, the descent of the docking platform 21 and the movement of the support device 5 toward the first workstation P1 can occur simultaneously for a period of time, provided that the docking platform 21 and the support device 5 do not interfere with each other.

[0231] In some embodiments, in steps S07 and S08, the descent of the docking platform 21 and the movement of the support device 5 occur simultaneously over a period of time.

[0232] In this embodiment, the time for the support device 5 to move coincides at least partially with the time for the docking platform 21 to descend, which helps to optimize the battery swapping cycle and improve battery swapping efficiency.

[0233] In some embodiments, in steps S07 and S08, when the docking platform 21 descends to the fourth preset height, the support device 5 starts to move from the second work station P2, wherein the fourth preset height is higher than the second preset height H2 and lower than the first preset height H1.

[0234] For example, the fourth preset height may be higher than, equal to or lower than the third preset height H3.

[0235] In this embodiment, the support device 5 is moved only after the docking platform 21 has descended a certain distance. This helps to reduce the risk of interference or collision between the support device 5 and the docking platform 21, and improves the reliability of battery swapping.

[0236] In some embodiments, in step S07c, the docking platform 21 does not support the battery device 8, therefore, the fourth preset height may be higher than the third preset height H3.

[0237] In some embodiments, the battery swapping method further includes step S09: the battery swapping device 2 moves again from the third station P3 to the fourth station P4. Step S09 is performed after step S07.

[0238] The execution order of steps S09 and S08 is not important. In some examples, step S08 is executed first, followed by step S09; in other examples, step S09 is executed first, followed by step S08. In still other examples, the movement of the battery swapping device 2 and the movement of the supporting device 5 occur simultaneously for a period of time during steps S09 and S08.

[0239] In some embodiments, in steps S08 and S09, the movement of the battery swapping device 2 and the movement of the supporting device 5 occur simultaneously over a period of time.

[0240] In this embodiment, the time for the battery swapping device 2 to move coincides at least partially with the time for the support device 5 to move, which helps to optimize the battery swapping cycle and improve battery swapping efficiency.

[0241] In some embodiments, step S06 includes:

[0242] S06a: The battery swapping device 2, carrying the replaced battery device 8, moves from the fourth station P4 to the third station P3.

[0243] S06b: The support device 5 moves from the second station P2 to the first station P1 to separate the battery device 8 carried by the battery swapping device 2 from the chassis 91 during the movement of the battery swapping device 2.

[0244] S06c: After the battery swapping device 2 reaches the third station P3, the support device 5 moves from the first station P1 to the second station P2 again until it reaches the second station P2.

[0245] In steps S06a and S06b, the timing at which the battery swapping device 2 begins to move and the timing at which the support device 5 begins to move can be the same or different. Optionally, the support device 5 may begin to move towards the first station P1 only after the battery device 8 carried by the battery swapping device 2 has moved to the lower side of the support device 5.

[0246] In step S06, the time when the battery swapping device 2 arrives at the third station P3 can be the same as or different from the time when the support device 5 arrives at the first station P1. Optionally, the time when the battery swapping device 2 arrives at the third station P3 can be the same as the time when the support device 5 arrives at the first station P1.

[0247] In steps S06c and S07a, the moment when the connecting platform 21 begins to lift and the moment when the supporting device 5 begins to move toward the second workstation P2 can be the same or different. In some examples, step S06c is executed first, followed by step S07a. In other examples, in steps S06c and S07a, the lifting of the connecting platform 21 and the movement of the supporting device 5 occur simultaneously for a period of time; optionally, when the connecting platform 21 is lifted to a fifth preset height, the supporting device 5 moves to the second workstation P2. The fifth preset height can be higher than the second preset height but lower than the first preset height.

[0248] During the process of the battery swapping device 2 transferring the fully charged battery device 8 toward the vehicle 9, the support device 5 can move together with the battery swapping device 2 to block water droplets, dust and other impurities falling from the chassis 91, thereby reducing the impurities falling onto the battery device 8, reducing the risk of battery device 8 failure and the risk of replacing the failed battery device 8 with the vehicle 9, and improving the reliability of battery swapping.

[0249] In some embodiments, the battery swapping station includes a plurality of support devices 5.

[0250] In some embodiments, step S01 includes:

[0251] S01a: After vehicle 9 enters the battery swapping station and passes the support device 5 at the first work station P1, identify the battery device 8 of vehicle 9 and determine the support device 5 that needs to be moved during the battery swapping process.

[0252] S01b: The support device 5 that needs to be moved moves from the first station P1 to the second station P2.

[0253] In some examples, the vehicle 9 has a large wheelbase, the battery unit 8 is large in size, or there are many battery units 8, so all the support devices 5 need to be moved during the battery swapping process. Therefore, each support device 5 needs to be moved in steps S01, S03, S04, S08, etc.

[0254] In other examples, the vehicle 9 has a smaller wheelbase, the battery unit 8 is smaller in size, or the number of battery units 8 is smaller, so only some of the support devices 5 need to move during the battery swapping process. In this case, only the support devices 5 corresponding to the battery units 8 need to move in steps S01, S03, S04, S08, etc.

[0255] In some embodiments, the battery swapping device 2 includes multiple independently liftable docking platforms 21.

[0256] The battery swapping method also includes step S00, which further includes: identifying the battery device 8 of the vehicle 9 and determining the connection platform 21 that the battery swapping device 2 needs to lift during the battery swapping process. For example, step S00 is performed before step S02.
