Description

Technical Field

[0001] The utility model relates to the technical field of automobile batteries, and in particular to a movable automobile battery module with a unified fast battery replacement mode. Background Art

[0002] In recent years, with the popularization of new energy vehicles, the development of automotive battery packs has become increasingly rapid.

[0003] The current electric vehicle battery pack is composed of multiple battery cells stacked in series or parallel. During use, the battery pack can be charged through a charging pile, but this charging method takes a long time. It takes about half an hour to fully charge the battery, and it takes 6 hours or more to charge the battery slowly, which is inconvenient for people to use. If the battery pack is replaced, since the specifications and sizes of battery packs from different manufacturers are not uniform, different models cannot share the same battery, which is also inconvenient for people to use.

[0004] At present, there are three main battery replacement methods in the automotive battery replacement market:

[0005] 1. Lifting and battery replacement (basically eliminated);

[0006] 2. Side battery swap: Since the small battery pack needs to be placed under the car from the side, the number of small battery packs placed in different car bodies is different, but different battery packs must have independent wiring harnesses, cooling systems, BMS systems, and shells. If a large car is equipped with four small battery packs at the same time, there will be four (wiring harnesses, cooling systems, BMS systems, and shells), which will cause the energy density of the four small battery packs to be lower than that of the large battery pack, thereby shortening the driving range, so side battery swapping has not become mainstream;

[0007] 3. Bottom battery replacement: This method is the current mainstream battery replacement method, but the disadvantage of bottom battery replacement is that the battery pack specifications cannot be unified, which is inconvenient to use. When replacing the battery, the car needs to be driven into the battery replacement channel of the battery replacement station, and then the body (wheel) positioning pins on the ground are used to position the body, and then the body is lifted up for battery replacement. The battery replacement efficiency is poor and it is very time-consuming. Utility Model Content

[0033] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-10 , the utility model embodiment includes:

[0035] A movable automobile battery module with a unified rapid battery replacement mode is connected to a battery management system BMS in a car, and its structure includes: a battery cell assembly 1 and a circulation connection assembly 2.

[0036] The battery cell assembly comprises a battery body, an outer shell, a connection protrusion 12, and a connection recess 13. The battery body can directly adopt conventional battery products in the art.

[0037] The battery cell body is arranged in the outer shell, and the positive electrode 14 and the negative electrode 15 which are respectively connected to the positive and negative poles of the battery cell body are arranged on the outer shell. The connecting protrusion and the connecting recess of the hemispherical or arc-shaped structure are respectively arranged at the two ends of the outer shell, so that in two adjacent battery cells, the connecting recess in one battery cell is connected with the connecting protrusion in the other battery cell, so that the battery cells can turn smoothly in the flow channel.

[0038] The connection convex part and the connection concave part are insulating structures, and a hollow conductive ring (electrode ring) 16 (the electrode ring is the positive electrode) is arranged in the center of the connection convex part, and a conductive sheet 17 (the negative electrode) is arranged in the center of the connection concave part. When the battery cell is in the straight part of the battery cell flow channel, the connection concave part is connected to the connection convex part and the conductive sheet is in contact with the insulated connection convex part. At this time, the adjacent battery cells are not connected in series; when the battery cell is in the curved part of the battery cell flow channel, the connection concave part is connected to the connection convex part and the conductive sheet is in contact with the electrode ring. At this time, the adjacent battery cells are connected in series, and the battery cells at both ends of the curved part are connected to the battery cells in the straight part.

[0039] Among them, the conductive ring and the conductive sheet are just a kind of conductive structure, such as a copper ring and a copper sheet, which have no polarity themselves. The polarity of the conductive ring and the conductive sheet is determined by the connection with the electrodes of the internal battery body. The copper ring and the copper sheet can be tightly fixed in the outer surface or groove of the non-conductive connecting concave part and the connecting convex part by means of inlay bonding, etc., and the conductive pins on the copper ring and the copper sheet are directly connected to the positive and negative electrodes of the battery body through the outer shell or through the conductive layer to conduct electricity. The copper ring and the copper sheet are not subjected to force, and the outer shell needs to be kept smooth.

[0040] Further preferably, the connecting protrusion, the connecting recess and the outer shell are an integrated structure.

[0041] Further preferably, the outer shell includes a shell body 111 and a cover body 112, the cover body is threadedly connected to the shell body, and the connecting protrusion is arranged on the cover body or the connecting protrusion directly serves as the cover body.

[0042] Further preferably, the positive electrode and the negative electrode are conductively connected to the battery body through a wire, a copper busbar, and a conductive layer.

[0043] Further preferably, the cross-section of the outer shell is a circular or polygonal structure.

[0044] The circulation connection assembly includes a circulation storage shell 21 , a battery cell flow channel 22 , a battery output port 23 , a battery input port 24 , a guide roller 25 , and a conductive elastic connector 26 .

[0045] The circulation storage housing is provided with a set of battery output ports and battery input ports, which can be connected to the battery replacement port on the vehicle body. A hollow tubular cell flow channel for conveying battery cells is provided in the circulation storage housing, and one end of the cell flow channel is connected to the battery output port, and the other end is connected to the battery input port, so as to realize the input, output and storage of battery cells. The length of the battery cells and the cell flow channel can be set according to actual usage requirements.

[0046] Further preferably, one or more groups of battery cell flow channels are provided in the circulation storage shell, and the specific number of flow channels may vary due to the module design and the size of the battery module installation space (battery compartment) in the vehicle body. Adjacent battery cell flow channels are connected end to end to form a circulation loop of the battery cell assembly. In this way, not only can the number of battery cells in the battery module be adjusted according to actual usage requirements and adapt to battery compartments of different sizes in different vehicle bodies, but also the corresponding current or energy output can be achieved.

[0047] The car battery compartment is a rectangular space where every inch of land is valuable. Generally speaking, if the battery cells are laid out according to the size of current No. 1 batteries, the battery compartment can probably be covered with three layers of middle and lower flow channels.

[0048] Further preferably, each of the battery core flow channels may be a quasi-spiral flat layer structure or a quasi-spiral micro-drooping structure.

[0049] Further preferably, when each group of battery cell flow channels is a planar structure (a spiral-shaped flat layered structure) and multiple groups of battery cell flow channels are parallel to each other, the ends of two adjacent groups of battery cell flow channels with planar structures can be connected by a transition flow channel, and the transition flow channel as a whole or its two ends have a certain curvature, so that the battery cells can be smoothly transmitted and flowed in the battery cell flow channels and the transition flow channels.

[0050] The quasi-spiral flat layer structure, that is, each layer of the battery core flow channel is a flat structure and is wound in a spiral manner from the outer edge to the center or from the center to the outer edge, or first from the outer edge to the center and then from the center to the outer edge. At this time, the battery core flow channels of each layer are connected through the transition flow channel 27.

[0051] like Figure 6As shown, a group of spiral-shaped flat-layer structured cell flow channels are set up, and the cell flow channels allow the battery cells to flow in two directions, namely, first from outside to inside (white part) and then from inside to outside (black part). Since the cell input and output ports are on the outside of the car, the cell flow channel entrance can only flow from outside to inside, so this kind of flow channel setting method of first flowing in from outside to inside and then flowing out from inside to outside in a flow channel level is a more ideal flow channel setting method, which not only facilitates the flow of battery cells, but also facilitates the production and processing of manufacturers.

[0052] like Fig. 9 As shown, a plurality of groups of vertically parallel spiral-shaped flat-layer structured cell flow channels are provided, and each layer of cell flow channels allows the battery cells to flow in two directions: the cell flow channels of the top layer first flow from outside to inside and then from inside to outside, and the ends thereof flow to the outer ring of the cell flow channels of the second layer through transition flow channels, the cell flow channels of the second layer also first flow from outside to inside and then from inside to outside, and the ends thereof flow to the outer ring of the cell flow channels of the third layer through transition flow channels, the cell flow channels of the third layer still first flow from outside to inside and then from inside to outside, and the ends thereof are connected to the output end.

[0053] Spiral-shaped micro-drooping structures such as Fig.10 As shown: the cell flow channel is spirally arranged from top to bottom and the side width gradually decreases and then gradually increases. The number of cells accommodated by three cycles is basically the same as the number of cells in the three-layer spiral flat structure.

[0054] The characteristic of this structure is that it is sometimes thick and sometimes thin from top to bottom. This is because it adopts a bidirectional winding flow method from outside to inside and then from inside to outside, which is similar to the current mosquito coils: when the two mosquito coils connected at the center are slightly pulled apart up and down, a shape with a side width that changes from thick to thin and then to thick again will be formed, which is a spiral-shaped micro-drooping structure; if the pulled apart mosquito coils are merged and restored, it will be a level, which is a spiral-shaped flat structure.

[0055] By adopting a spiral-like micro-drooping structure, all flow channels can have a slight tilt angle from top to bottom, so that a height difference can be formed, so that the principle of converting gravitational potential energy into kinetic energy can be used, so that the battery monomer assembly will not only generate a downward flow force due to gravity under the action of external thrust / pressure, but also further improve the smoothness of the input and output of the battery monomer assembly. At the same time, under the action of the guide rollers and guide rollers and gravitational potential energy, the angle of the curve part becomes appropriately smaller, which will also quickly push all battery monomers out of the body without increasing the volume of the battery compartment.

[0056] Further preferably, the cross-section of the battery core flow channel is a circular structure.

[0057] Further preferably, a sealing end cap is provided on each of the battery output port and the battery input port, wherein the sealing end cap can be connected to the battery output port and the battery input port by means of threads, screws, buckles, etc., and a soft rubber or other elastic structure can be provided inside the sealing end cap to tighten the outer shell of the battery cell in the flow channel.

[0058] The battery cell flow channel includes a straight portion 221 and a curved portion 222. Multiple sets of guide rollers are rotatably arranged on the side walls of the straight portion, and multiple sets of guide rollers 223 are circumferentially arranged in the curved portion. The inner ends of the guide rollers and the guide rollers are in contact with the outer wall of the battery cell to facilitate the movement and transmission of the battery cell.

[0059] Further preferably, the diameter of the straight portion is slightly larger than the diameter of the battery cell, the diameter of the curved portion is slightly larger than the diameter of the straight portion, and the curvature of the curved portion is gentle, so that the battery cell can turn smoothly and prevent getting stuck.

[0060] Further preferably, guide rollers are also provided in the transition channel.

[0061] The conductive elastic connector is connected to the tube wall of the battery cell flow channel and can exist in the gap between the flow channels. Its outer end is connected to a conductive structure such as a wire or a copper busbar to facilitate the series / parallel connection of the battery cells and can be connected to the BMS system. Its inner end passes through the through hole on the battery cell flow channel and contacts the electrode of the battery cell to connect and conduct. The conductive elastic connector has a certain elasticity to ensure that it is in close contact with the battery cell or the electrode thereon, thereby improving the stability and accuracy of the conductive connection. Among them, the setting position of the conductive elastic connector can be matched and set according to the length of the battery cell and the battery cell flow channel, so that when the battery cell flow channel is full of battery cells (that is, the battery cells are all at the target power supply position), the conductive elastic connector can be matched and connected with the electrode on the battery cell.

[0062] Further preferably, the conductive elastic connector includes a positive electrode connecting piece and a negative electrode connecting piece.

[0063] Further preferably, the conductive elastic connector is arranged on one side / both sides of the battery core flow channel.

[0064] Further preferably, the conductive elastic connector is provided with a conductive roller in contact with the battery cell, which helps to transmit the battery cell and reduce friction while maintaining conduction.

[0065] When the battery module is low on power, you can choose to charge the battery cell assembly (the charging method can use existing conventional charging equipment and methods), or you can choose to directly replace the battery cell assembly to save charging waiting time.

[0066] When replacing a battery cell assembly, unscrew the sealed end cap on the battery replacement port or the output and input port, align the fully charged battery cell assembly with the battery input port, and then apply a thrust or pressure to the fully charged battery cell assembly (the thrust or pressure can be provided by existing or traditional loading equipment such as a cylinder, a manipulator, an automatic loader, an automatic feeder, a battery conveying system, or even manually, and this case only aims at the technical improvement of the automotive battery module itself, and does not involve improvements to the pushing equipment). The pressing in of the new battery cell assembly will push the old battery cell assembly originally located in the battery cell flow channel to be discharged to the battery output port; when all the old battery cell assemblies are completely out of the battery cell flow channel, the fully charged battery cell assembly just fills the battery cell flow channel, and after closing the end caps with spring structures at both ends, the position of all new battery cell assemblies can be fixed, so that the battery cell assembly is in full contact with the conductive elastic connector for power supply, and the replaced battery cell assembly can be charged outside the car in preparation for use in another car.

[0067] This method effectively avoids the problem of long waiting time for charging in the existing charging mode, so that electric vehicles can complete battery replacement in a short time, and the specifications of battery cells for battery replacement can be unified, suitable for large / small battery compartments of different models. Among them, the battery cells of the battery cell assembly can be replaced or scrapped when they are old, but the outer shell can be recycled continuously.

[0068] The present application only improves the specific structure of the battery module. The series-parallel connection method of the wires connected to each battery in the battery module can be connected in series and parallel according to actual needs (the specific connection method is not the improvement point of this case). The connection settings and connection methods of the battery module and other components of the vehicle and the BMS system can adopt the common knowledge and existing technologies in the field.

[0069] The beneficial effects of the movable automobile battery module with a unified fast battery replacement mode of the utility model are: it unifies the basic structure of the battery cell assembly and provides power supply, replaces the battery cell by replacing / changing the battery cell, and realizes the connection, storage and circulation transmission of the battery cell through the battery cell flow channel, so that different car models share the same battery, which is convenient for people to use, effectively shortens the charging and battery replacement time of electric vehicles, and greatly improves work efficiency.

[0070] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
