Technical Field

[0001] This utility model relates to the field of battery swapping station technology, specifically to a battery rack and a battery storage system having the same. Background Technology

[0002] With the development of the new energy industry, battery swapping has become an important way to replenish energy for new energy vehicles. Battery racks are devices within battery swapping stations used to store and charge batteries. Compact battery storage layouts and efficient battery transfer solutions are crucial to the operating costs of battery swapping stations.

[0003] Existing battery rack layouts typically involve placing one rack on each side of a battery lift, using the lift to transfer batteries from the rack compartments. However, this layout is limited by the height of the battery swapping station, which is constrained by regulations and transportation conditions, preventing further increases in the number of battery compartments. Even if the number of compartments were increased, transferring batteries between compartments remains difficult, failing to meet the growing demand for battery swapping. Utility Model Content

[0004] In view of this, the present invention provides a battery rack and a battery storage system having the same, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0005] To achieve the aforementioned objective, a first aspect of this utility model provides a battery rack, comprising multiple layers of battery storage compartments distributed along the Z-direction. Each battery storage compartment includes a first compartment and a second compartment, or a transfer compartment and a second compartment. The transfer compartment and the first compartment are distributed along the Z-direction, and the transfer compartment, the first compartment, and the second compartment are respectively distributed adjacent to each other along the X-direction. Both the first compartment and the second compartment are used to store batteries. The transfer compartment is used to temporarily store batteries when the first compartments are not empty. Battery transfer devices are provided on both sides of the battery rack in the Y-direction to transfer batteries between the first compartment and the second compartment.

[0006] In the battery rack as described above, optionally, the battery transfer device includes a claw that can extend into the battery storage compartment to grip both sides of the battery, the battery including a positioning pin, and the Z-axis height of the claw within the battery storage compartment being between the various beams of the battery storage compartment and the positioning pin.

The mounting base includes a claw head extending into the battery storage compartment. The claw head protrudes upward from the mounting base, and the lower end of the claw head forms a groove with the mounting base. The claw portion is embedded in the groove.

[0008] In the battery rack described above, optionally, the battery storage position includes side roller racks located on both sides in the Y direction, the bottom of the mounting base is recessed upward and forms an upward recessed clearance groove with the claw portion, the clearance groove being used to avoid the side roller rack.

[0009] Optionally, in the battery rack described above, the battery rack may further include a first sensor disposed on the side of the first compartment closer to the second compartment, and / or a second sensor disposed between the first compartment and the second compartment, and / or a third sensor disposed in the second compartment away from the first compartment. The first sensor is used to monitor the battery storage status in the first compartment, the second sensor is used to monitor the middle part between the first compartment and the second compartment, and the third sensor is used to monitor the battery storage status in the second compartment.

[0010] Optionally, in the battery rack as described above, the battery transfer device includes a fourth sensor located in the X direction near the center of the second compartment, the fourth sensor being movable in the Z direction to monitor the battery storage status within the second compartment.

[0011] Optionally, in the battery rack described above, the battery rack may further include a charging device disposed in each of the battery storage compartments, the charging device being used to charge and / or limit the batteries stored in the battery storage compartment.

[0012] Optionally, in the battery rack described above, a second water baffle is installed above the charging device.

[0013] Optionally, the battery rack described above may also include a first water baffle plate disposed on the top beam above the first compartment. The X-axis dimension of the first water baffle plate is matched with the X-axis dimension of the first compartment to shield the upper battery from water or debris falling when it moves between the first compartment and the second compartment.

[0014] To achieve the aforementioned objectives, a second aspect of the present invention provides a battery storage system, including a battery lifter and a battery rack as described in any one of the first aspects above. The battery lifter is located on the side of the battery rack in the X direction close to the first compartment and the transfer compartment, for conveying the battery to the first compartment and the transfer compartment, or removing the battery from the first compartment and the transfer compartment.

Detailed Implementation

[0033] Referring to the accompanying drawings and specific embodiments, the structure, composition, features, and advantages of the battery rack, battery storage system, and battery swapping method of the present invention will be described by way of example below. However, all descriptions should not be construed as limiting the present invention in any way.

[0034] Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the various drawings, the present invention still allows for any combination or deletion of these technical features (or their equivalents) without any technical obstacle. Therefore, these further embodiments according to the present invention should also be considered within the scope of the description herein.

[0035] It should also be noted that the terms “inner,” “outer,” “top,” “bottom,” “upper,” “lower,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship of the battery rack shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0036] Furthermore, the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "third," "fourth," or "fifth" may explicitly or implicitly include at least one of those features.

[0037] In the description of this disclosure, "multi-layered" means at least two layers, such as two, three or more, unless otherwise explicitly specified.

[0038] like Figure 1 As shown, the direction of the battery entering and exiting is taken as the X direction, the horizontal direction of the battery rack 1 is taken as the Y direction, and the direction of the height of the battery rack 1 is taken as the Z direction.

[0039] Combination Figure 1 and Figure 6 The battery rack 1 proposed in this utility model includes multi-layer battery storage positions 10 distributed along the Z direction. The battery storage positions 10 include a first compartment 2 and a second compartment 3, or a transfer compartment and a second compartment 3.

[0040] Both the first compartment 2 and the second compartment 3 are used to store batteries 8. The first compartment 2 and the second compartment 3 allow two batteries 8 to be stored in the battery storage position 10 of this layer, thereby increasing the storage capacity of batteries 8 in the entire battery rack 1. The transfer compartment and the first compartment 2 are distributed along the Z direction, and the transfer compartment and the first compartment 2 are respectively adjacent to the second compartment 3 along the X direction. The transfer compartment is used to temporarily store batteries 8 when the first compartment 2 is not empty. Batteries 8 can be transferred between the first compartment 2 and the second compartment 3, and can be transferred into or out of the battery rack 1 through the first compartment 2. In addition, batteries 8 can be transferred between the transfer compartment and the second compartment 3.

[0041] To facilitate the transfer of battery 8 between the first compartment 2 and the second compartment 3, such as Figure 1 As shown, battery transfer devices 4 are provided on both sides of the Y direction of the battery rack 1. Both sides of the battery transfer devices 4 include claws 7. The claws 7 can extend into the battery storage position 10 and smoothly grasp both sides of the battery 8 to drive the battery to transfer between the first compartment 2 and the second compartment 3, the transfer compartment and the second compartment 3, so as to improve the battery transfer efficiency.

[0042] like Figure 2 As shown, in order for the battery transfer device 4 to move between the first compartment 2 and the second compartment 3 on each floor, combined with Figure 3 As shown, the battery rack 1 has a first clearance area 14 in the Z direction from the bottom to the top. The first clearance area 14 is used for the pawl 7 of the battery transfer device 4 to move in the Z direction. That is, the pawl 7 can move along the Z direction of the first clearance area 14 to reach the battery storage position 10 of each layer.

[0043] Furthermore, such as Figure 2 As shown, the first clearance zone 14 is located at the same position between the first compartment 2 and the second compartment 3 on each floor, so as to facilitate the rapid movement of the claw 7 in the Z direction, thereby improving the battery transfer efficiency.

[0044] Specifically, such as Figure 3 As shown, a connecting beam 13 is provided between the first compartment 2 and the second compartment 3 of the battery storage compartment 10. The connecting beam 13 is recessed into the interior of the battery storage compartment 10 to form a first clearance area 14 together with the beam frame of the first compartment 2 and the second compartment 3.

[0045] Combination Figure 2 , Figure 4 and Figure 5 It can be seen that the battery transfer device 4 is a frame structure, located between the first compartment 2 and the second compartment 3, and extends from the bottom layer to the top layer of the battery rack 1.

[0046] Specifically, such as Figure 5As shown, the battery transfer device 4 includes a first connecting plate 41 arranged along the top X direction of the battery rack 1, and a second connecting plate 42 arranged along the bottom X direction of the battery rack 1. The battery transfer device 4 also includes a Z-axis module 6 for driving the pawl 7 to move in the Z direction, and an X-axis module 5 for driving the pawl 7 to move in the X direction.

[0047] Specifically, such as Figure 5 As shown, the Z-axis module 6 includes a Z-guide rail 60, which is installed at both ends of the first connecting plate 41 and the second connecting plate 42, extending from the bottom layer to the top layer of the battery rack 1. The Z-axis module 6 also includes a Z-slider 65, a Z-motor 61, and a Z-reducer 62, all mounted on the Z-guide rail 60. The Z-motor 61 and the Z-reducer 62 are connected to the Z-guide rail 60 via a coupling 63 and a drive shaft 64 to drive the Z-slider 65 to move along the Z-guide rail 60 in the Z direction.

[0048] Combination Figure 4 and Figure 5 The X-axis module 5 includes an X-guide rail 50, which is parallel to the first connecting plate 41 and the second connecting plate 42. The second connecting plate 42 is provided with a groove (e.g., Figure 4 As shown), a fourth clearance area 44 is formed between the battery rack 1 and the bottom support of the battery rack 1, so that the forklift forks can pass through the fourth clearance area 44 into the bottom of the battery rack 1 and lift the entire battery rack 1 for transportation.

[0049] like Figure 5 As shown, the two ends of the X-guide rail 50 are respectively mounted on the Z-sliding seats 65 of the two Z-guide rails 60, that is, the X-guide rail 50 is located between the two Z-guide rails 60, and the X-guide rail 50 can move along the Z-guide rails 60 in the Z direction with the Z-sliding seats 65. The X-axis module 5 also includes an X-sliding seat 52 disposed on the X-guide rail 50, as well as an X-motor 53 and an X-reducer 54, which are used to drive the X-sliding seat 52 to move along the X-guide rail 50 in the X direction.

[0050] Combination Figure 4 As can be seen, the X motor 53 is located at the end of the X guide rail 50 and moves in the Z direction with the X guide rail 50. Therefore, a second Z-direction clearance zone 34 is provided at the end of the battery holder 1 near the X guide rail 50 to avoid the X motor 53, so that the X motor 53 can move smoothly in the Z direction with the X guide rail 50.

[0051] The pawl 7 is installed on the X sliding seat 52, that is, the pawl 7 can move along the X guide rail 50 in the X direction with the X sliding seat 52, and can move along the Z guide rail 60 in the Z direction with the X guide rail 50 at the first clearance area 14.

[0052] Thus, the claw 7 can reach the battery storage position 10 of each layer along the Z direction through the first clearance area 14, and can also move between the first compartment 2 and the second compartment 3 of each layer along the X direction to realize the transfer of batteries between the first compartment 2 and the second compartment 3 of each layer.

[0053] Combination Figure 6 It can be clearly seen that the pawl 7 is located at the end of the second compartment 3 away from the first compartment 2. The battery 8 is stored in the second compartment 3. The battery 8 includes a positioning pin 81 located on the Y-side for positioning with the vehicle and a locking body 82 for cooperating with the pawl 7. The locking body 82 serves as the battery gripping part and can be locked onto the pawl 7.

[0054] The second compartment 3 includes various beam frames, such as a roller frame 17 for supporting the battery 8, side roller frames 18 located on both sides in the Y direction, and an inclined support beam 19 installed below the roller frame 17 to reinforce the roller frame 17. The roller frame 17 and the inclined support beam 19 are both beam frames of the battery rack 1.

[0055] It should be noted that when the pawl 7 is stored in the battery at a height of 10 in the Z direction, it is maintained between the inclined support beam 19, the side roller frame 18, and the positioning pin 81 to avoid the inclined support beam 19, the side roller frame 18, and the positioning pin 81, so that the pawl 7 can move smoothly in the X direction.

[0056] When transferring battery 8, the pawl 7 can lock the lock body 82 and move the lock body 82, thereby moving the entire battery 8.

[0057] Specifically, such as Figure 7 As shown, the pawl 7 includes a mounting base 71 for mounting on the X sliding base 52 and a claw portion 73 for locking the lock body 82. The pawl 7 locks the lock body 82 through the claw portion 73. The separate mounting base 71 and claw portion 73 of the pawl 7 facilitate the replacement of the claw portion 73 to accommodate different types of batteries 8. Mounting base 71 can be an L-shaped plate, with one end mounted on the X sliding base 52 and the other end being a claw head 72 that extends into the battery storage compartment 10. The claw head 72 is U-shaped, the same shape as the claw part 73, with the U-shaped opening facing the inside of the battery storage compartment 10, for mounting the claw part 73.

[0058] Furthermore, such as Figure 7 As shown, the claw head 72 protrudes upward from the mounting base 71, and the lower end of the claw head 72 cooperates with the mounting base 71 to form a groove. The claw part 73 is embedded in the groove, so that the claw part 73 is more firmly installed on the claw head 72. Furthermore, the upward lifting design of the claw head 72 can raise the claw part 73 to a suitable height to avoid the inclined support beam 19, the side roller frame 18, and the positioning pin 81.

[0059] Optionally, the bottom of the claw head 72 and the bottom of the claw part 73 are provided with a first guide angle 74. The first guide angle 74 is used to guide the lock body 82 so that the claw 7 can quickly be positioned with the lock body 82.

[0060] like Figure 7 As shown, the inner side of the U-shaped opening at the end of the claw head 72 may also be provided with a second guide angle 75, which can guide the lock body 82 to be inserted into the U-shaped opening.

[0061] like Figure 7 As shown, the outer U-shaped corners of the claw head 72 and claw part 73 can also be provided with a third guide angle 76, which is used to prevent collision with the battery 8.

[0062] Furthermore, such as Figure 7 As shown, the bottom of the L-shaped plate of the mounting base 71 is recessed upwards at the corner, forming an upwardly recessed clearance groove 77 with the claw portion 73. (Combined) Figure 6 The clearance groove 77 is used to avoid the side roller frame 18.

[0063] To further determine the location of the transport battery, such as Figure 2 Sensors are installed in all three areas circled in the center. Specifically, Figure 2 The circled area I represents the end of the first position 2 that is closest to the second position 3. Figure 2 The area circled in the middle, area II, is the region between the first position 2 and the second position 3. Figure 2 The circled area III is the end of the second position 3 that is furthest from the first position 2.

[0064] Specifically, Figure 2 The circled area I, combined with Figure 8 As can be seen, a first sensor 21 is provided on the side of the first compartment 2 near the second compartment 3. The first sensor 21 is used to monitor the battery storage status in the first compartment 2.

[0065] exist Figure 8 In this embodiment, the first compartment 2 has a roller frame 17 for carrying batteries. A first sensor 21 is located at the end of the roller frame 17 near the second compartment 3, and the first sensor 21 is at the same Z-axis height as the roller frame 17, or at a lower Z-axis height than the roller frame 17. Therefore, when the battery is placed in the first compartment 2, the first sensor 21 is located at the bottom of the battery, closer to the battery 8 in the first compartment 2, making the monitored data more accurate and not hindering the transfer of the battery 8 in the first compartment 2.

[0066] In other embodiments, the first sensor 21 may also be located on the Y-side or Z-top of the first compartment 2, as long as it does not obstruct the transfer of the battery 8 in the first compartment 2.

[0067] Figure 2The circled area II, combined with Figure 9 As shown, a second sensor 16 is provided between the first compartment 2 and the second compartment 3. The second sensor 16 is used to monitor the middle part between the first compartment 2 and the second compartment 3 to prevent the battery 8 stored in the first compartment 2 from exceeding the storage range of the first compartment 2 and shifting towards the side closer to the second compartment 3; similarly, it also prevents the battery stored in the second compartment 3 from exceeding the storage range of the second compartment 3 and shifting towards the side closer to the first compartment 2, thereby effectively avoiding collisions between the batteries stored in the first compartment 2 and the batteries stored in the second compartment 3. Moreover, the second sensor 16 can also monitor the battery transfer between the first compartment 2 and the second compartment 3.

[0068] exist Figure 9 In one embodiment, the second sensor 16 is disposed at the top between the first compartment 2 and the second compartment 3 of the top layer to monitor the area between the first compartment 2 and the second compartment 3 of each layer from the top down, so as to monitor the storage and operation of the batteries 8 in each layer, and to simplify the installation of the second sensor 16.

[0069] In an optional embodiment, the second sensor 16 can be positioned between the first compartment 2 and the second compartment 3 on each layer to accurately monitor the battery storage and transfer status on each layer.

[0070] Figure 2 The circled area III, combined with Figure 10 It can be seen that the second compartment 3 is equipped with a third sensor 31, which is used to monitor the battery storage status of the second compartment 3.

[0071] exist Figure 10 In one embodiment, the third sensor 31 is located at the end of the second compartment 3 away from the first compartment 2, that is, the third sensor 31 is aligned with the end of the battery stored in the second compartment 3, thereby preventing the battery stored in the second compartment 3 from exceeding the storage range of the second compartment 3.

[0072] Furthermore, from Figure 10 It can also be seen that a blocking member 32 can be provided at the end of the second compartment 3. The blocking member 32 is used to hold the end of the battery to prevent the battery from exceeding the storage range of the second compartment 3 and colliding with the beam at the end of the second compartment 3 of the battery rack 1.

[0073] exist Figure 10 In one embodiment, a mounting bracket 33 is provided at the beam frame at the end of the second compartment 3. The third sensor 31 and the blocking component 32 are both mounted on the mounting bracket 33 to facilitate the unified installation of the third sensor 31 and the blocking component 32.

[0074] Furthermore, an inlet / outlet sensor (not shown in the figure) can be installed at the end of the first compartment 2 away from the second compartment 3. The inlet / outlet sensor is used to monitor the entry and exit of batteries into and out of the battery rack 1 in the first compartment 2. The inlet / outlet sensor can be installed at the top of the first compartment 2 on the top floor to monitor the end of each first compartment 2 away from the second compartment 3 from the top down, so as to monitor the storage and operation of batteries in each layer, and simplify the installation of the inlet / outlet sensor.

[0075] In an optional embodiment, the entrance / exit sensor can be set at the end of the first compartment 2 on each floor to accurately monitor the battery storage and transfer status on each floor.

[0076] Therefore, the entrance / exit sensor and the first sensor 21 can work together to monitor the battery storage status in the first compartment 2. The second sensor 16 and the third sensor 31 can work together to monitor the battery storage status in the second compartment 3.

[0077] Thus, the entrance / exit sensor, the first sensor 21, the second sensor 16, and the third sensor 31 work together to monitor the operation of the battery between the first compartment 2 and the second compartment 3.

[0078] To further monitor the battery storage status in the second compartment 3, such as Figure 4 As shown, the battery transfer device 4 includes a fourth sensor 43, which is located in the X direction near the center of the second compartment 3. The fourth sensor 43 can move in the Z direction with the X guide rail 50. Correspondingly, a third clearance area 35 is provided at the first connecting plate 41 to avoid the fourth sensor 43 moving there.

[0079] The fourth sensor 43 is used to monitor the battery storage status in the second compartment 3, assisting the third sensor 31 in confirming the battery storage status in the second compartment 3. As shown in the figure, the second sensor 16 and the third sensor 31 detect the two ends of the second compartment 3 respectively. It can be understood that the X-axis length of the second compartment 3 is greater than the length of the battery. When the battery 8 is slightly offset in the X-axis, that is, it is outside the monitoring range of the second sensor 16 and the third sensor 31, the fourth sensor 43, located near the middle of the second compartment 3, can further determine the battery storage status of the second compartment 3.

[0080] It should be noted that the aforementioned battery storage status refers to whether the corresponding compartment has batteries stored, and whether the stored batteries are placed in the correct position, i.e., not exceeding the battery storage range of the compartment. Furthermore, each first compartment 2 on each floor is equipped with a first sensor 21, and each second compartment 3 on each floor is equipped with a third sensor 31.

[0081] like Figure 2As shown, in order to further limit the position of the batteries in the compartments, each layer of the battery rack 1 of this utility model is provided with a charging device 15. More specifically, the first compartment 2 and the second compartment 3, the transfer compartment and the second compartment 3 are all provided with charging devices 15. The charging devices 15 are used to charge and / or limit the position of the batteries 8 stored in the corresponding first compartment 2, second compartment 3 or transfer compartment.

[0082] exist Figure 2 In one embodiment, the charging device 15 is located at the top of the first compartment 2 and the second compartment 3 on each floor. When the battery is stored in place, the charging device 15 presses down to connect to the battery charging port for charging, while simultaneously restricting the position of the battery to prevent it from moving. In other embodiments, the location of the charging device 15 is not limited and can be set according to the direction of the battery charging port, as long as it can press down to limit the battery.

[0083] The charging device 15 can work with the second sensor 16 and the first sensor 21 to limit the battery stored in the first compartment 2; and the charging device 15 can work with the third sensor 31 and the blocking member 32 to limit the battery stored in the second compartment 3.

[0084] To prevent water from entering the upper battery layer, such as Figure 11 As shown, a second water baffle 83 is provided above each charging device 15 on each layer. The position of the second water baffle 83 is matched with the position of the water and electricity interface of the battery 8 to block water or debris falling from the upper battery storage compartment. Furthermore, a first water baffle 23 is provided on the top beam above the first compartment 2 on each layer to prevent water or debris from falling from the upper battery 8 when it moves between the first compartment 2 and the second compartment 3.

[0085] Specifically, such as Figure 11 As shown, the X-axis dimension of the first baffle plate 23 matches the X-axis dimension of the first compartment 2, that is, the first baffle plate 23 is laid along the X-axis on the top beam of the first compartment 2 to block water and impurities dripping when the battery 8 moves. The top beam may include a middle crossbeam 24 in the Y-axis direction, and the first baffle plate 23 is installed between the middle crossbeam 24 and the two end crossbeams.

[0086] like Figure 12 As shown, the battery storage system proposed in this utility model includes the aforementioned battery rack 1 and battery lifter 11. The battery lifter 11 is located on the side of the battery rack 1 in the X direction close to the first compartment 2 and the transfer compartment, for conveying batteries 8 to the first compartment 2 and the transfer compartment, or removing batteries 8 from the first compartment 2 and the transfer compartment.

[0087] In this embodiment, such as Figure 12As shown, taking a seven-layer battery storage compartment 10 as an example, the seven rows and two columns in the figure indicate each compartment of the battery rack 1. Understandably, the number of layers in the battery storage compartment 10 is unlimited and can be set according to the specifications of the specific battery swapping station where it is placed.

[0088] like Figure 12 As shown, the battery lift 11 is located on one side near the first compartment 2 of the battery rack 1, and is used to transfer batteries from the battery swapping equipment to the first compartment 2 of each layer of the battery rack 1, or to transfer batteries in the first compartment 2 of each layer to the battery swapping equipment.

[0089] To facilitate battery transfer, the first compartments 2 on two layers of battery rack 1 are kept empty and do not store batteries; these are referred to as the first transfer compartment and the second transfer compartment. The first transfer compartment and the second transfer compartment are used for transferring batteries, i.e., temporarily storing batteries.

[0090] like Figure 12 In this embodiment, the first transfer compartment and the second transfer compartment are respectively a first compartment on one floor and a first compartment on the second floor, and the first transfer compartment and the second transfer compartment are arranged adjacent to each other. Therefore, the battery lifting machine 11 can transfer batteries into or out of the first transfer compartment and the second transfer compartment without lifting or by lifting only one floor, thereby reducing the travel distance of the battery lifting machine 11, speeding up the transfer of batteries, and reducing the operating cost of the battery lifting machine 11.

[0091] In other embodiments, the first and second transfer compartments can also be the first compartments 2 of other layers, as long as they can temporarily store batteries. As long as two layers of the battery rack 1 have empty first compartments 2, it is not necessary to specifically designate two layers of first compartments 2 as the first and second transfer compartments, thus allowing for more flexible battery transfer. The battery swapping in the aforementioned battery storage system, such as... Figure 13 As shown, the steps are as follows: Step A: Determine if a fully charged battery is located in the first compartment 2. If yes, proceed to step B; otherwise, proceed to step F.

[0092] Step B: Remove the depleted battery from the vehicle and transfer it to the first transfer compartment via battery lift 11.

[0093] Step C: Transfer the fully charged battery from the first compartment 2 using the battery lift 11, and then execute steps D and R respectively; Step D: Transfer the depleted battery from the first transfer bay to the vacant first bay 2 using the battery lift 11, and then proceed to step Q.

[0094] Step F: Determine if the fully charged battery is located in the second compartment 3, which is not on the same floor as the first transfer layer and the second transfer layer. If yes, proceed to step G. If no, proceed to step M.

[0095] Step G: Use the battery lifter 11 to transfer the fully charged batteries from the first compartment 2 on the same floor to the first transfer compartment for temporary storage.

[0096] Step H: Transfer the fully charged battery from the second compartment 3 to the first empty compartment 2 on the same floor using the battery transfer device 4.

[0097] Step 1: The depleted battery is removed from the vehicle and transferred to the second transfer compartment.

[0098] Step J: Transfer the fully charged battery from the first compartment 2 using the battery lift 11, and then execute steps K and R respectively.

[0099] Step K: The depleted battery is transferred from the second transfer compartment to the vacant first compartment 2 by the battery hoist 11, and then transferred to the vacant second compartment 3 on the same floor by the battery transfer device 4. Steps L and Q are executed respectively.

[0100] Step L: Transfer the temporarily stored batteries from the first transfer compartment to the vacant first compartment 2 using the battery lift 11, and then proceed to step Q.

[0101] Step M: Transfer the fully charged battery from the second compartment 3 to the first transit compartment using the battery transfer device 4. It should be noted that this step assumes the fully charged battery is located in the second compartment 3 on the same floor as the first transit compartment.

[0102] Step N: Remove the depleted battery from the vehicle and transfer it to the second transfer compartment.

[0103] Step O: Transfer the fully charged battery from the first transfer compartment using the battery lift 11, and then execute steps P and R respectively.

[0104] Step P: Transfer the depleted battery from the second transfer compartment to the first transfer compartment via the battery hoist 11, and then transfer it to the second compartment 3 on the same floor via the battery transfer device 4. Then proceed to step Q.

[0105] Step Q: Charge the battery using charging device 15.

[0106] Step R: Install the fully charged battery into the vehicle.

[0107] It should be noted that in the aforementioned steps, when batteries need temporary storage, they are preferentially placed in the first transfer compartment for ease of explanation. In actual use, batteries can be placed in the nearest transfer compartment according to the actual situation for convenient transportation.

[0108] The battery rack 1 of this invention has multiple battery storage compartments 10. Each battery storage compartment 10 has a first compartment 2 and a second compartment 3, meaning each battery storage compartment 10 can hold two batteries, thereby increasing the battery storage capacity of the entire battery rack 1 within a limited battery swapping station. Furthermore, this invention also includes a battery transfer device 4 located on both sides of the battery rack 1 in the Y direction, used to transfer batteries between the first compartment 2 and the second compartment 3 of each layer, thereby accelerating the battery transfer speed and improving the efficiency of battery transfer. Moreover, sensors are installed at the first compartment 2, the second compartment 3, and between the first compartment 2 and the second compartment 3 to monitor the battery storage and transfer process. These sensors, in conjunction with the battery compartment charging device 15, limit the position of the batteries to prevent collisions.

[0109] This utility model also provides a battery storage system having the aforementioned battery rack 1. The battery storage system includes a battery lifter 11 disposed near the first compartment 2 of the battery rack 1. The battery storage system has all the features of the aforementioned battery rack 1, and therefore also has its corresponding advantages.

[0110] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
