In addition, the character " / " in this application generally represents that the front and rear associated objects have an "or" relationship.

[0035] In the embodiments of the application, the same reference signs represent the same parts, and for the sake of brevity, the detailed description of the same parts is omitted in different embodiments. It should be understood that the thickness, length and width of various components in the embodiments of the application shown in the drawings, as well as the overall thickness, length and width of the integrated device, are only exemplary and should not constitute any limitation on the application.

[0036] "Multiple" appearing in this application refers to two or more (including two).

[0037] In the present application, a battery refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in the present application can include a battery module or a battery pack, etc. Some batteries can include a box for packaging one or more battery cells or multiple battery modules. The box can prevent liquid or other foreign matter from affecting the charging or discharging of the battery cell. Of course, there are also some batteries that do not include the above-mentioned box and are directly arranged in the battery installation cabin of the electric device.

[0038] In the present application, the battery cell can include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium lithium-ion battery, a sodium-ion battery, or a magnesium-ion battery, etc., and the embodiments of the present application are not limited thereto. The battery cell can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc., and the embodiments of the present application are not limited thereto. The battery cell is generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells, and soft package battery cells, and the embodiments of the present application are not limited thereto.

[0039] For example, the battery cell can include a shell, an electrode assembly, and an electrolyte, and the shell is used to accommodate the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode tab, a negative electrode tab, and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode tab and the negative electrode tab to work. The positive electrode tab includes a positive current collector and a positive active material layer, and the positive active material layer is coated on the surface of the positive current collector. The positive current collector that is not coated with the positive active material layer protrudes from the positive current collector that has been coated with the positive active material layer, and the positive current collector that is not coated with the positive active material layer serves as a positive electrode tab. Taking a lithium-ion battery as an example, the material of the positive current collector can be aluminum, and the positive active material can be lithium cobaltate, lithium iron phosphate, ternary lithium, or lithium manganate, etc.

[0040] The negative electrode tab includes a negative current collector and a negative active material layer, and the negative active material layer is coated on the surface of the negative current collector. The negative current collector that is not coated with the negative active material layer protrudes from the negative current collector that has been coated with the negative active material layer, and the negative current collector that is not coated with the negative active material layer serves as a negative electrode tab. The material of the negative current collector can be copper, and the negative active material can be carbon or silicon, etc. In order to ensure that the fuse does not occur when passing a large current, the number of positive electrode tabs is multiple and stacked together, and the number of negative electrode tabs is multiple and stacked together.

[0041] The material of the separator can be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly can be a winding type structure or a laminated type structure, and the embodiments of the present application are not limited thereto.

[0042] A pole or the like connected to the tab can be provided on the battery monomer as an electrical connection part of the battery monomer. In addition, the battery monomer can have a pressure relief part. When the internal pressure of the battery monomer is too high (for example, thermal runaway), the pressure relief part is used to release the substances (for example, gas, liquid, particulate matter, etc.) inside the battery monomer to reduce the internal pressure of the battery monomer and avoid the battery monomer from being rapidly pressurized inside to cause dangerous accidents such as explosion of the battery monomer. For example, the pressure relief part can be a pressure relief valve, a pressure relief sheet, or the like.

[0043] In the prior art, after the battery is manufactured, the battery needs to be temporarily stored in a battery bin. At present, the battery bin is designed to be relatively simple, and is generally arranged in an array in the warehouse. A transport vehicle is used to transport the battery to the corresponding position. The transport vehicle is provided with a lifting device. The battery is lifted by the lifting device to be placed in the required battery bin. This design is difficult to match the limitations of some factory sites and the functional requirements of the storage location.

[0044] Therefore, the battery handling system provided in the present application comprises a rack, a handling device, and a lifting driving device. The middle part of the rack has a transfer channel, and the outer periphery of the rack is used to form a battery bin. The handling device is arranged in the transfer channel and is used to handle the battery. The lifting driving device comprises a first driving assembly and a first transmission assembly. The first transmission assembly is arranged in the transfer channel and is connected with the handling device. The first driving assembly is arranged at the outer periphery of the rack and is connected with the first transmission assembly. The first driving assembly drives the first transmission assembly to drive the handling device to lift.

[0045] In the battery handling system with the above structure, the layout of the entire battery handling system is more reasonable and compact, the height of the battery handling system is effectively reduced, the height space limitation requirement is met, and the limitations of some factory sites and the functional requirements of the storage location are matched. The entire transport arrangement of the corresponding battery is more compact and reasonable, the battery transport efficiency can be improved, and the storage density and space utilization rate can be improved.

[0046] Next, the battery handling system 100 according to the embodiments of the present application is described with reference to the accompanying drawings.

[0047] As shown in FIGS. 1-4, the battery handling system 100 according to some embodiments of the present application comprises a rack 10, a handling device 20, and a lifting driving device. The middle part of the rack 10 has a transfer channel 101, and the outer periphery of the rack 10 is used to form a battery bin 102. The handling device 20 is arranged in the transfer channel 101 and is used to handle the battery. The lifting driving device comprises a first driving assembly 31 and a first transmission assembly 32. The first transmission assembly 32 is arranged in the transfer channel 101 and is connected with the handling device 20. The first driving assembly 31 is arranged at the outer periphery of the rack 10 and is connected with the first transmission assembly 32. The first driving assembly 31 drives the first transmission assembly 32 to drive the handling device 20 to lift.

[0048] The rack 10 is a support structure of the whole system, and a transfer channel 101 is arranged in the middle part for transferring and carrying the batteries. The outer periphery of the rack 10 is used to form a battery compartment 102, i.e. a storage position of the batteries, so that the rack 10 is generally annular.

[0049] The carrying device 20 is a device for grabbing and carrying the batteries, which can move up and down in the transfer channel 101 to realize carrying of the batteries at different height positions.

[0050] The lifting driving device is used to control the lifting of the carrying device 20, and specifically includes a first driving assembly 31 and a first transmission assembly 32. The first driving assembly 31 is used to provide power to drive the whole carrying device 20. The first transmission assembly 32 is a structure connecting the first driving assembly 31 and the carrying device 20, so that the first driving assembly 31 can drive the transmission assembly, and then drive the carrying device 20 to perform the lifting action. The first transmission assembly 32 can include structures such as ropes, gears, chains or belts.

[0051] Among them, the first transmission assembly 32 is arranged in the transfer channel 101, and the first driving assembly 31 is arranged on the outer periphery of the rack 10, that is, the first driving assembly 31 and the first transmission assembly 32 are arranged in the horizontal direction, so as to reduce the space occupied by the lifting driving device in the vertical direction.

[0052] That is, in the embodiment, the battery compartment 102 is arranged on the outer periphery of the carrying device 20 and the first transmission assembly 32. The carrying device 20 can transport the batteries from the middle part of the battery compartment 102 into the battery compartment 102. The whole transportation arrangement is more compact and reasonable, so as to improve the battery transportation efficiency and improve the storage density and space utilization.

[0053] The first driving assembly 31 is arranged on the outer periphery of the rack 10. The first driving assembly 31 can utilize the space of the battery compartment 102. For example, the first driving assembly 31 can be arranged at the bottom of part of the battery compartment 102, so as to reduce the space occupied by the first driving assembly 31 in the vertical direction and the space occupied in the horizontal direction. The whole battery carrying system 100 is more reasonable and compact in layout, effectively reduces the height of the battery carrying system 100, and meets the height space limitation requirement of the site, so as to match the site limitation and storage function requirement of part of the factory building.

[0054] In the above technical solution, the whole battery carrying system 100 is more reasonable and compact in layout, effectively reduces the height of the battery carrying system 100, and meets the height space limitation requirement of the site, so as to match the site limitation and storage function requirement of part of the factory building. Correspondingly, the whole transportation arrangement of the batteries is more compact and reasonable, which can improve the battery transportation efficiency, improve the storage density and space utilization.

[0055] As shown in FIG. 1, in some embodiments, the first transmission assembly 32 includes a winding drum 321 and a rope assembly 322. The winding drum 321 is arranged at the bottom of the transfer channel 101, and the first driving assembly 31 is connected to the winding drum 321 for driving the winding drum 321 to rotate. The rope assembly 322 includes a plurality of ropes, at least a portion of which is connected to the winding drum 321. The rack 10 has a plurality of positioning wheel sets 13, and at least a portion of the plurality of ropes passes through the positioning wheel sets 13 and is connected to the carrying device 20.

[0056] The surface of the winding drum 321 can be wound with ropes, and the rotation of the winding drum 321 can wind or release the ropes, thereby controlling the tension and length of the ropes. The ropes are ropes connecting the winding drum 321 and the carrying device 20, which can be steel wire ropes, synthetic fiber ropes, or other suitable rope materials for load. The first driving assembly 31 is directly or indirectly connected to the winding drum 321, and the winding drum 321 is driven to rotate by the first driving assembly 31, thereby controlling the winding and unwinding of the ropes.

[0057] The positioning wheel set 13 is a series of wheels installed on the rack 10, which changes the direction of the ropes, so that the ropes can pass through the wheels and be connected to the carrying device 20, thereby reducing the friction of the ropes and improving the efficiency of the system.

[0058] By placing the winding drum 321 at the bottom of the transfer channel 101, the first driving assembly 31 can be arranged at the bottom of the battery compartment 102, thereby arranging the power part of the entire lifting driving device at the bottom of the rack 10, facilitating maintenance and replacement, etc.

[0059] A portion of the ropes passes through the positioning wheel set 13 upwardly and is connected to the carrying device 20. When the first driving assembly 31 drives the winding drum 321 to rotate, the tension of the ropes is transmitted to the carrying device 20, so that the carrying device 20 can be lifted.

[0060] Thus, the vertical movement of the carrying device 20 in the transfer channel 101 is realized to meet the needs of carrying batteries at different heights. By controlling the rotation of the winding drum 321, precise positioning and stable carrying of the carrying device 20 can be achieved. The use of multiple ropes can provide better load distribution and stability, and reduce the swing or imbalance problem that may be caused by a single rope.

[0061] As shown in FIG. 1, in some embodiments, the rope assembly 322 includes a main rope 3221, a rope adapter 3222, and a plurality of auxiliary ropes 3223. One end of the main rope 3221 is connected to the winding drum 321, the other end of the main rope 3221 is connected to the rope adapter 3222, the first ends of the plurality of auxiliary ropes 3223 are connected to the rope adapter 3222, and the plurality of auxiliary ropes 3223 pass through the corresponding positioning wheel sets 13 so that the second ends of the plurality of auxiliary ropes 3223 are connected to the carrying device 20.

[0062] The main rope 3221 and the auxiliary rope 3223 are connected through the rope adapter 3222, so that one-to-multiple conversion can be realized, the rope can be connected with the winding drum 321, the lifting driving device is simplified, and connection and cooperation of the overall structure are facilitated. Meanwhile, the synchronization of movement of the multiple auxiliary ropes 3223 can be improved, and the stability of lifting of the carrying device 20 is improved, and the probability of inclination and shaking of the carrying device 20 is reduced.

[0063] As shown in FIGS. 1 and 2, in some embodiments, the carrying device 20 is annular, each positioning wheel set 13 is arranged on the upper side of the carrying device 20, the positioning wheel set 13 at least includes a first positioning wheel 131 and a second positioning wheel 132, the center of the first positioning wheel 131 is located on the inner side of the carrying device 20, the center of the second positioning wheel 132 is located on the outer side of the carrying device 20, the first end of the auxiliary rope 3223 is connected to the rope adapter 3222, and the auxiliary rope 3223 is sequentially wound around the inner side of the carrying device 20, the first positioning wheel 131 and the second positioning wheel 132, so that the second end of the auxiliary rope 3223 is connected on the outer side of the carrying device 20.

[0064] The carrying device 20 is annular, which is beneficial to uniform distribution of load, and can facilitate multi-directional movement of the carrying device 20 in the transfer channel 101. Each positioning wheel set 13 is composed of at least two positioning wheels, i.e., the first positioning wheel 131 and the second positioning wheel 132, so as to change the direction of the rope and enable the rope to be stably connected with the carrying device 20.

[0065] Specifically, the first end of the auxiliary rope 3223 is connected to the rope adapter 3222, the auxiliary rope 3223 is sequentially wound around the inner side of the carrying device 20, the first positioning wheel 131 and the second positioning wheel 132, and the second end of the auxiliary rope 3223 is connected to the outer side of the carrying device 20, so as to complete the closed loop of the entire rope system, wherein the first positioning wheel 131 can guide the auxiliary rope 3223 from the inner side of the carrying device 20 to the outer side; the second positioning wheel 132 can further change the direction of the auxiliary rope 3223, so that the rope can be connected downward to the carrying device 20.

[0066] Therefore, the carrying device 20 can stably lift in the transfer channel 101, and through the configuration of the auxiliary rope 3223 and the positioning wheel set 13, the uniformity of the tension of the rope is ensured, the problems of inclination or instability of the carrying device 20 caused by uneven tension of the rope are reduced, and the stability of the entire system is improved.
