Description

Technical Field

[0001] The present application relates to the field of batteries, and more specifically, to a battery-swap vehicle and battery. Background Art

[0002] With the surge in the number of electric vehicle users, battery-swap vehicles that can replace batteries at battery swap stations are gradually becoming the choice of more users.

[0003] When replacing batteries in current battery swapping vehicles at battery swapping stations, only a single battery can be replaced, which cannot meet the growing diversified battery swapping needs of users. For example, a battery swapping vehicle is equipped with multiple batteries, but the user only wants to replace one battery. Traditional battery swapping vehicles cannot meet the user's independent and flexible battery swapping needs, which easily increases the user's energy consumption and cost when traveling. Summary of the invention

[0004] The embodiments of the present application provide a battery-swap vehicle and battery, which can adapt to the battery-swap needs of different users and provide users of battery-swap vehicles with a more diverse and flexible battery-swap solution.

[0005] In a first aspect, a battery-swap vehicle is provided, comprising a battery compartment, wherein the battery compartment is arranged inside the battery-swap vehicle, the battery compartment is used to accommodate a plurality of batteries, and each of the batteries can independently supply power to the battery-swap vehicle.

[0006] The solution provided by the present application is to set a battery compartment capable of accommodating multiple batteries in a battery swapping vehicle. Each battery installed in the battery swapping compartment independently supplies power to the battery swapping vehicle, so that users can flexibly choose the number of batteries to be configured on the battery swapping vehicle according to their own needs, thereby increasing the diversity of battery swapping for battery swapping vehicles and providing more battery swapping solutions for users of battery swapping vehicles.

[0007] In a possible implementation, the battery compartment includes: a first sub-battery compartment and a second sub-battery compartment, wherein the battery is fixedly disposed in the first sub-battery compartment, and the battery is detachably disposed in the second sub-battery compartment.

By designing a battery compartment structure with a first sub-battery compartment and a second sub-battery compartment, the battery swapping vehicle can be equipped with fixed batteries and replaceable batteries at the same time, increasing the battery configuration scheme of the battery swapping vehicle and further expanding the battery swapping schemes that can be used in the battery swapping vehicle.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0119] In the present application, the battery may include a lithium-ion battery, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, etc., and the embodiments of the present application do not limit this. The battery cells in the battery may be cylindrical, flat, rectangular, or other shapes, and the embodiments of the present application do not limit this.

[0120] The battery described in the embodiments of the present application refers to a physical module including one or more battery cells to provide electrical energy. For example, the battery mentioned in the present application may include a battery pack, etc.

[0121] In order to meet different power requirements, the battery may include multiple battery cells, wherein the multiple battery cells may be connected in series, in parallel, or in a hybrid connection, wherein the hybrid connection refers to a mixture of series and parallel connections. Optionally, multiple battery cells may first be connected in series, in parallel, or in a hybrid connection to form a battery module, and multiple battery modules may then be connected in series, in parallel, or in a hybrid connection to form a battery. Optionally, multiple battery cells may also be directly connected in series, in parallel, or in a hybrid connection to form a battery. The battery is further disposed in an electrical device to provide electrical energy to the electrical device.

[0122] The battery may also include a box body, which is a hollow structure inside, and multiple battery cells are contained in the box body, and the box body can prevent liquid or other foreign matter from affecting the charging and discharging of the battery cells. For example, multiple battery cells are connected in parallel, in series, or in a mixed combination and arranged in the box body.

[0124] The battery-swap vehicle mentioned in this application can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc., and the embodiments of this application do not limit this. According to the classification of use, the battery-swap vehicle mentioned in this application can be a passenger vehicle, an operating vehicle, a logistics vehicle, etc., and the embodiments of this application do not limit this.

[0125] A motor, a controller, and a battery may be provided inside the vehicle, and the controller is used to control the battery to power the motor. The battery may be used to power the vehicle, for example, the battery may be used as the operating power source of the vehicle, and may be used in the circuit system of the vehicle, for example, to meet the working power requirements during the starting, navigation, and operation of the vehicle. In another embodiment of the present application, the battery may be used not only as the operating power source of the vehicle, but also as the driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0126] In recent years, with the surge in the number of electric vehicle users, the battery swapping business has developed accordingly. Battery swapping refers to the process of replacing batteries in a battery-equipped vehicle at a battery swapping station. A battery swapping station is generally equipped with a battery swapping platform, a mobile battery swapping device, a control system, etc. Among them, the mobile battery swapping device is used to transport the battery to the battery swapping vehicle, remove the battery from the battery swapping vehicle, and install the battery to be installed into the battery compartment of the battery swapping vehicle. It can be a rail guided vehicle (RGV) or an automatic guided vehicle (RGV).

[0127] Existing battery-swap vehicles can usually only achieve a single battery replacement, which cannot meet the diverse battery replacement needs of users. Single battery replacement refers to removing the battery from the battery-swap vehicle and installing a battery to be installed with the same parameters as the battery model, size, power, full power, chemical system, etc. to the battery-swap vehicle. In real life, batteries are updated and replaced, and users' battery replacement needs have become more diverse with the expansion of battery-swap vehicle usage scenarios. For example, a user equipped with an old model battery wants to replace a new model battery. For another example, a user who only drives in the city wants to replace a battery with a smaller full power to meet travel needs. In addition, when multiple batteries are installed in the battery compartment of a battery-swap vehicle, multiple batteries are usually required to power the battery-swap vehicle together, so that all batteries in the battery compartment must be replaced during battery replacement. The battery replacement needs of users who only want to replace one battery in the battery compartment are not supported. Alternatively, users of battery-swap vehicles equipped with multiple batteries only need to remove one battery without installing a new battery. A single battery pack replacement cannot meet the above user needs, which can easily cause unnecessary energy consumption during user travel, increase the user's economic cost, and is not conducive to improving user experience.

[0128] In view of this, the present application provides a battery-swap vehicle that can support a variety of battery-swap solutions, so that users can more conveniently and flexibly choose appropriate battery-swap services according to their own needs, reduce useless energy consumption, save users' economic costs and improve user experience.

[0129] Figure 1 This is a bottom view of a battery-swap vehicle 100 provided in the present application, in which a battery compartment 10 and a battery 20 are shown.

[0130] like Figure 1 As shown, the battery swap vehicle 100 includes a battery compartment 10, which is disposed inside the battery swap vehicle 100. The battery compartment 10 is used to accommodate a plurality of batteries 20, and each battery 20 can independently supply power to the battery swap vehicle 100.

[0131] Among them, the battery compartment 10 is used to accommodate multiple batteries 20, that is, the battery swap vehicle 100 can be installed with multiple batteries 20, or only one battery 20 can be installed. In the case where the battery swap vehicle is installed with multiple batteries 20, each battery 20 can independently power the battery swap vehicle 100, which means that when one or several batteries 20 are disassembled for charging or maintenance, the remaining batteries 20 can continue to supply power to the battery swap vehicle 100 to ensure its normal operation. Moreover, when one of the batteries 20 is damaged, the remaining batteries 20 can continue to supply power to the battery swap vehicle 100.

[0132] The battery-swap vehicle 100 provided in the embodiment of the present application is provided with a battery compartment 10 capable of accommodating a plurality of batteries 20, and each battery 20 can independently supply power to the battery-swap vehicle 100, so that the user can flexibly choose the number of batteries 20 provided in the battery compartment 10. For example, in the case where the battery-swap vehicle 100 can be equipped with a plurality of batteries 20, the user can choose to assemble a plurality of batteries 20 on the battery-swap vehicle 100 to meet travel needs when a long-distance trip is required; or the user can choose to assemble only one battery 20 to reduce the weight of the battery-swap vehicle 100 and reduce unnecessary energy consumption when a short-distance trip is required. Therefore, the battery-swap vehicle 100 provided in the embodiment of the present application provides users with a more flexible and diverse battery-swap solution.

[0133] like Figure 1 As shown, in one embodiment, the battery compartment 10 includes a first sub-battery compartment 10a and a second sub-battery compartment 10b, wherein the battery 20 is fixedly disposed in the first sub-battery compartment 10a, and the battery 20 is detachably disposed in the second sub-battery compartment 10b.

[0134] Among them, the battery compartment 10 that can accommodate multiple batteries 20 includes multiple subspaces for installing batteries 20, and each subspace accommodates at least one battery 20. The battery 20 fixedly connected to the battery compartment 10 refers to a fixed battery or a fixed battery pack (referred to as a fixed pack), and the battery detachably connected to the battery compartment 10 refers to a replaceable battery or a replaceable battery pack (referred to as a quick-change pack). The fixed battery or fixed pack is usually welded in the battery compartment 10 and does not need to be replaced. When the battery 20 is low in power, the battery swap vehicle 100 charges the fixed battery or fixed pack through charging piles and other equipment to supplement the power required for travel. The fixed battery or fixed pack does not need to be replaced, which can greatly reduce the economic cost of users using the battery swap vehicle 100, but the charging time of the fixed battery or fixed pack is longer, which increases the user's time cost and does not support long-distance or emergency travel needs. The replaceable battery or quick-change pack is usually fixed in the battery compartment 10 through a connecting structure and can be disassembled and replaced by a mobile battery swap device in a battery swap station. Replaceable batteries or quick-change packs enable the battery-swap vehicle 100 to quickly replenish the electrical energy needed for travel without having to wait for the battery to charge, but the economic cost is relatively high.

[0135] In this embodiment, the first sub-battery compartment 10a is used to accommodate fixed batteries or fixed packs, and the second sub-battery compartment 10b is used to accommodate replaceable batteries or quick-change packs, which enables the battery-swap vehicle 100 to be compatible with two different forms of batteries 20, thereby enabling the battery-swap vehicle 100 to have both a charging mode and a battery-swap mode. When the user has plenty of time and can replenish the power required for travel by charging, the battery 20 disposed in the first sub-battery compartment 10a is charged in the charging mode; when the user is in a hurry and needs to quickly replenish the power required for travel, the battery 20 disposed in the second sub-battery compartment 10b is replaced in the battery-swap mode.

[0136] Therefore, the battery-swap vehicle 100 provided in this embodiment designs the first sub-battery compartment 10a and the second sub-battery compartment 10b in the battery compartment 10, so that the battery-swap vehicle 100 can be compatible with different forms of batteries 20, thereby having a charging mode and a battery-swap mode. Therefore, users can choose a more suitable solution according to actual conditions and their own needs, thereby expanding the battery-swap solutions that the battery-swap vehicle can support.

[0137] In one embodiment, the batteries 20 are arranged along a first direction x, and the first direction x is the traveling direction of the battery-swap vehicle 100 .

[0138] In such Figure 1 In the illustrated embodiment, the battery compartment 10 can accommodate two batteries 20. In other embodiments, the battery compartment 10 can accommodate a larger number of batteries. By arranging the batteries 20 along the first direction x, the weight of the batteries 20 is symmetrically distributed on the left and right sides of the battery swap vehicle 100, which helps to improve the balance of the battery swap vehicle 100 and helps to improve the safety performance of the battery swap vehicle 100. It should be understood that the symmetrical distribution of the weight of the batteries 20 on the left and right sides of the battery swap vehicle 100 can mean that the weight of the batteries 20 on the left and right sides of the battery swap vehicle 100 is completely equal, or the difference in weight of the batteries 20 on the left and right sides of the battery swap vehicle 100 is less than a certain threshold. Exemplarily, the difference is less than or equal to 5% of the weight of the battery 20.

[0139] like Figure 1 As shown, in one embodiment, the length L1 of the battery 20 in the first direction x is less than the length L2 of the battery 20 in the second direction y, and the second direction y is the width direction of the battery swap vehicle 100. That is, in the battery compartment 10, the long side of the battery 20 is parallel to the width direction of the battery swap vehicle 100.

[0140] By horizontally arranging the battery 20 in the battery compartment 10, the battery compartment 10 can accommodate a larger number of batteries 20 under a certain volume, which helps to improve the space utilization of the battery compartment 10, so that the battery-swap vehicle 100 has more power options, further enriching the user's battery-swap solutions.

[0141] In one embodiment, a bracket 11 is disposed in the battery compartment 10 , and the bracket 11 includes at least one support beam 111 parallel to the width direction of the battery swap vehicle 100 , and the support beam 111 divides the battery compartment 10 into a plurality of sub-spaces for accommodating the battery 20 .

[0142] It should be understood that the sizes of the multiple subspaces divided by the support beam 111 may be the same or different. This application does not limit this. Figure 1 In the illustrated embodiment, the support beam 111 divides the battery compartment 10 into two sub-spaces of the same size, and the multiple sub-spaces are used to accommodate multiple batteries 20 of the same size or model. In some other embodiments, the support beam 111 divides the battery compartment 10 into multiple sub-spaces of different sizes, and the multiple sub-spaces are used to accommodate multiple batteries 20 of different sizes or models.

[0143] Figure 2 Schematic diagram of a battery compartment 10 and a battery 20 according to an embodiment of the present application.

[0144] In one embodiment, a disassembly structure 30 is provided on the battery 20 , and a connection portion 31 corresponding to the disassembly structure 30 is provided on the battery compartment 10 . The disassembly structure 30 is used to connect with the connection portion 31 to fix the battery 20 in the battery compartment 10 .

[0145] The battery swap vehicle 100 may vibrate or be impacted during driving. By providing a disassembly structure 30 and a connection portion 31, the battery 20 can be stably installed in the battery compartment 10, and a stable supply of electricity can be maintained when the battery swap vehicle 100 vibrates or is impacted. The disassembly structure 30 can specifically be a snap structure, a lock structure, or the like that can stably connect the battery 20 to the battery swap compartment 10 and can release the connection relationship under certain conditions. In one embodiment, the connection portion 31 has a track extending in the direction of gravity, and the connection portion 31 is configured to lock the disassembly structure 30 when the disassembly structure 30 moves upward along gravity to a predetermined position of the channel; and the connection portion 31 is configured to release the lock on the disassembly structure 30, so that the disassembly structure 30 can move downward under the action of the gravity of the battery 20 to leave the track. Among them, the "predetermined position" of the channel can be any appropriate position in the channel.

[0146] The disassembly structure 30 can be fixed on the battery 20 by welding, riveting, etc., and the connection part 31 can be fixed at the corresponding position in the battery compartment 10 by welding, riveting, etc. For each battery 20, the number of its disassembly structures 30 can be one or more. For example, when the battery 20 is small in size and light in weight, the battery 20 can be fixed by connecting only one disassembly structure 30 and the corresponding connection part 31 in the battery compartment 10; when the battery 20 is large in size and heavy in weight, two or even more disassembly structures 30 and the connection part 31 may be required to better fix the battery 20.

[0147] For a fixed battery or a fixed pack, the disassembly structure 30 may not be provided thereon, and the corresponding position in the battery compartment 10 may not be provided with the connecting portion 31.

[0148] In one embodiment, n disassembly structures 30 are disposed on the battery 20 at intervals, wherein n is a positive integer and n≥2.

[0149] like Figure 2 In the illustrated embodiment, four mutually spaced disassembly structures 30 are provided on the battery 20, and four corresponding connection parts 31 are provided at corresponding positions in the battery compartment 10. In some other embodiments, the number of disassembly structures 30 may be more or less. Compared with centrally arranging the disassembly structures 30 in one place, by arranging the disassembly structures 30 at intervals on the battery 20, the force-bearing structure of the battery 20 is more stable when it is fixed in the battery compartment 10 by the disassembly structures 30 and the connection parts 31.

[0150] In one embodiment, the disassembly structure 30 is disposed on a wall of the box of the battery 20 parallel to the second direction y.

[0151] In such Figure 2In the embodiment shown, four disassembly structures 30 are respectively arranged on the first wall 201 and the second wall 202 of the box body of the battery 20. The first wall 201 and the second wall 202 are both walls parallel to the second direction y. In some other embodiments, one disassembly structure 30 may be arranged on the first wall 201, and three disassembly structures 30 may be arranged on the second wall 202. The disassembly structure 30 is arranged on the wall of the box body parallel to the width direction (second direction x) of the battery 20 and the battery-swap vehicle 100, and the corresponding connection part 31 in the battery compartment 10 is also arranged on the wall of the battery compartment 10 parallel to the second direction y. As mentioned above, in order to arrange more batteries 20 in the battery compartment 10, the length L1 of the battery 20 in the first direction x is less than the length L2 of the battery 20 in the second direction y. Therefore, a larger number of disassembly structures 30 can be arranged on the wall of the battery 20 parallel to the second direction y, thereby improving the reliability and stability of the connection between the battery 20 and the battery compartment 10. In addition, since the battery 20 is longer in the second direction y, providing a disassembly structure 30 on the wall in this direction can also help prevent the battery 20 from bending or deforming in the second direction y, thereby improving the safety performance of the battery 20.

[0152] Figure 2 In the illustrated embodiment, the disassembly structure 30 is disposed on the first wall 201 and the second wall 202 and is connected to the connection portion 31 disposed on the support beam 111 of the bracket 11 in the battery compartment 10. In some other embodiments, the disassembly structure 30 may be connected to the connection portion 31 disposed directly at a corresponding position on the inner wall of the battery compartment; the connection portion 31 may also be disposed on the wall of the battery 20, so that the battery 20 is connected to the connection portion 31 of the adjacent battery 20 through the disassembly structure 30.

[0153] It should be understood that when a plurality of disassembly and replacement structures 30 are provided on the battery 20, all the disassembly and replacement structures 30 may be provided on the wall of the battery 20 box body parallel to the second direction y. In some other embodiments, part of the disassembly and replacement structures 30 may be provided on the wall of the battery 20 box body parallel to the second direction y, and the remaining disassembly and replacement structures 30 may be provided on other walls of the battery 20 box body, for example, the wall of the box body parallel to the first direction x, so as to reduce the shaking or collision of the battery 20 along the direction of travel of the battery-swap vehicle 100. The disassembly and replacement structures 30 provided on the wall of the box body parallel to the first direction x may be connected to the connecting portion 31 at the corresponding position in the battery compartment 10, or may be connected to the support beam 111 of the bracket 11 in the battery compartment 10. In other embodiments, all the disassembly and replacement structures 30 may be provided on the wall of the battery 20 box body parallel to the first direction x.

[0154] In one embodiment, the length L1 of the battery 20 in the first direction x satisfies: 440 mm ≤ L1 ≤ 800 mm, and the length L2 of the battery 20 in the second direction y satisfies: 1.5*L1≤L2≤2*L1.

[0155] Exemplarily, when the lengths of the battery 20 in the first direction x and the second direction y meet the above conditions, the disassembly structure 30 may be provided only on the wall of the case of the battery 20 parallel to the second direction y.

[0156] In one embodiment, 1100 mm ≤ L2 ≤ 1500 mm.

[0157] Figure 3 This is another schematic diagram of a battery compartment 10 and a battery 20 of the present application.

[0158] In one embodiment, the number n of the disassembly structures 30 is positively correlated with the length L2 of the battery 20 in the second direction y, and negatively correlated with the stiffness P of the battery 20 in the third direction z, where the third direction is the height direction of the battery-swap vehicle 100. Optionally, 2≤n≤4.

[0159] Specifically, if Figure 3 As shown, the number of disassembly structures 30 can be set according to the length L2 of the battery 20 in the second direction y and the stiffness of the battery 20 in the third direction y. For example, the longer the length L2 of the battery 20 in the second direction y, that is, the larger the size of the battery 20 in the lateral direction of the battery-swap vehicle 100, the more disassembly structures 30 can be set to ensure the stability of the connection between the battery 20 and the battery compartment 10. For another example, the greater the stiffness of the battery 20 in the third direction z, the greater the stress that the battery 20 can withstand in the third direction z, and the less likely it is to deform when subjected to vibration, shaking or impact. At this time, a relatively small number of disassembly structures 30 can be set to achieve a stable connection between the battery 20 and the battery compartment 10.

[0160] In one embodiment, Figure 2 As shown, the distance d1 between adjacent disassembly structures 30 satisfies: 0.5*L2≤d1≤0.8*L2. Optionally, 600mm≤d1≤1000mm.

[0161] Exemplarily, when the distance d1 between two adjacent disassembly structures 30 meets the above conditions, the disassembly structure 30 can be set only on the wall of the box body of the battery 20 parallel to the second direction y. In this embodiment, by setting the distance d1 between two adjacent disassembly structures 30 within a suitable range, the number of disassembly structures 30 that need to be set on the battery 20 can be minimized while ensuring a stable connection. Thus, the number of corresponding connecting parts 31 that need to be set in the battery compartment 10 is also reduced, which helps reduce the production cost of the battery-swap vehicle 100 and improve the battery-swap efficiency of the battery-swap vehicle 100.

[0162] Figure 4 This is a front view of a battery-swap vehicle 100 according to an embodiment of the present application.

[0163] For the battery compartment 10 arranged at the bottom of the battery swap vehicle 100, if the battery 20 in the battery compartment 10 is too large in the third direction z or is installed too low in the third direction, protruding from the bottom plate (also called the chassis) of the battery swap vehicle 100, it is easy for the battery swap vehicle 100 to scratch the battery 20 during driving, causing damage to the battery 20 and a reduction in its service life, and even causing safety problems in severe cases.

[0164] like Figure 4 As shown, in one embodiment, the length of the battery 20 in the third direction z is L3, and the distance between the geometric center of the disassembly structure 30 and the bottom plate of the battery-swap vehicle 100 is d2, where d2≤0.5*L3.

[0165] In this embodiment, by controlling the distance between the disassembly and replacement structure 30 on the battery 20 and the bottom plate of the battery-swap vehicle 100 within an appropriate range, it is possible to effectively avoid the battery 20 from being too close to the ground and causing scratches against the ground during the driving of the battery-swap vehicle 100, thereby improving the safety performance of the battery-swap vehicle 100.

[0166] Optionally, 80mm≤L3≤140mm; optionally, 10mm≤d2≤50mm.

[0167] Figure 5 It is another schematic diagram of another battery compartment 10 and battery 20 of the present application.

[0168] In one embodiment, the battery 20 includes a first sub-box 21 and a second sub-box 22, and the first sub-box 21 and the second sub-box 22 are connected. When the mechanical strength of the first sub-box 21 is greater than that of the second sub-box 22, the disassembly structure 30 is disposed on the first sub-box 21.

[0169] In such Figure 5In the illustrated embodiment, the battery 20 has two sub-boxes, namely, a first sub-box 21 and a second sub-box 22. In some other embodiments, the battery 20 may also have a greater or lesser number of sub-boxes. In the case where the battery 20 has multiple sub-boxes, due to factors such as cost or processing technology, the mechanical strength of the multiple sub-boxes may not be exactly the same. Therefore, the disassembly structure 30 may be disposed on a sub-box with greater mechanical strength, such as the first sub-box 21 described above, to prevent the battery 20 from being broken due to stress concentration at the disassembly structure 30.

[0170] Please continue to see Figure 5 In one embodiment, when the mechanical strength of the wall 211 of the first sub-box 21 parallel to the second direction y is greater than the mechanical strength of the wall 221 of the second sub-box 22 parallel to the second direction y, the disassembly structure 30 is arranged on the wall 211 of the first sub-box 21 parallel to the second direction y.

[0171] Figure 6 This is a schematic diagram of a battery 20 according to an embodiment of the present application.

[0172] In one embodiment, a wear-resistant structure 40 is disposed on the battery 20 .

[0173] Specifically, a wear-resistant structure 40 can be provided on at least one of the four walls of the battery 20 facing the battery compartment 10. The wear-resistant structure 40 can prevent the battery 20 from directly contacting the battery compartment 10 when shaking or moving, thereby protecting the battery 20 and helping to extend the service life of the battery 20. The wear-resistant structure 40 can be any structure that can protect the wall of the battery 20 facing the battery compartment 10, such as a block structure, a beam structure, a rib structure, etc. The material of the wear-resistant structure 40 can be the same as or different from the material of the wall of the battery 20, and the embodiments of the present application are not limited to this. In one embodiment, the mechanical strength of the wear-resistant structure 40 is greater than that of the wall of the battery 20. In another embodiment, the wear-resistant structure 40 can be a structure with a certain elasticity. The elastic structure can be a material of the wear-resistant structure 40 itself with a certain elasticity, or the wear-resistant structure 40 can include an elastic structure, such as a U-shaped groove.

[0174] For replaceable batteries or quick-change packs, the disassembly structure 30 disposed thereon usually protrudes from the frame of the battery 20. Therefore, after the battery 20 is fixed in the battery compartment 10, there is a certain gap between the wall of the battery 20 and the wall of the battery compartment 10; for the battery compartment 10 provided with a bracket 11, after the battery 20 is fixed on the bracket 11, there is also a certain gap between the wall of the battery 20 and the bracket 11. The existence of this gap makes it easy for the battery 20 to move under the influence of external force, which is not conducive to the stable connection between the battery 20 and the battery compartment 10.

[0175] In one embodiment, the wear-resistant structure 40 is disposed on the wall where the disassembly structure 30 is located.

[0176] Figure 6 The wear-resistant structure 40 shown is a beam-shaped structure. The disassembly structure 30 is arranged on two walls of the battery 20 parallel to the second direction y, and the wear-resistant structure 40 is also arranged thereon.

[0177] The wear-resistant structure 40 can be a separate structure, which is arranged on the battery 20 by welding, riveting, etc.; the wear-resistant structure 40 can also be a part of the battery 20 case extending outward, and the wear-resistant structure 40 is prepared by stamping, etc. during the preparation of the battery 20 case. By arranging the wear-resistant structure 40 on the wall where the disassembly structure 30 is located, on the one hand, it can protect the disassembly structure 30 protruding from the wall of the battery 20; on the other hand, it can also play a supporting and fixing role between the wall of the battery 20 and the wall of the battery compartment 10, improve the movement of the battery 20 caused by the gap between the battery 20 and the battery compartment 10, extend the service life of the battery 20 and further improve the safety performance of the battery swap vehicle.

[0178] In another embodiment, the wear-resistant structure 40 is disposed on the four walls of the battery 20 facing the battery compartment 10. The shape of the wear-resistant structure 40 disposed on the wall where the replacement structure 30 is located, the size of the wall protruding from the battery 20, and the shape of the wear-resistant structure 40 disposed on the other two walls, the size of the wall protruding from the battery 20 can be the same or different, and can be flexibly disposed according to different models of batteries 20, different sizes or different positions of battery compartments 10.

[0179] Figure 7 FIG. 2 is another schematic diagram of a battery 20 according to the present application.

[0180] Figure 7 In the illustrated embodiment, the length of the wear-resistant structure 40 protruding from the wall 221 of the battery 20 along the first direction x is greater than the length of the disassembly structure 30 protruding from the wall 221 of the battery 20 along the first direction x. In some other embodiments, the length of the wear-resistant structure 40 protruding from the wall 221 of the battery 20 along the first direction x may be equal to the length of the disassembly structure protruding from the wall 221 of the battery 20 along the first direction x.

[0181] In one embodiment, in the second direction y, the distance d3 between the two opposing wear-resistant structures 40 satisfies: 0.4≤d3 / L2≤0.7. It should be understood that the distance d3 between the two opposing wear-resistant structures 40 refers to the distance between the geometric centers of the two opposing wear-resistant structures.

[0182] In one embodiment, 700 mm ≤ d3 ≤ 750 mm.

[0183] In order to meet the user's long-distance driving needs, in addition to continuously improving the energy density of a single battery 20, it is also necessary to install a larger number of batteries 20 on the battery-swap vehicle 100.

[0184] In one embodiment, the battery-swap vehicle 100 includes a plurality of battery compartments 10 and a plurality of batteries 20, and at least two of the plurality of batteries 20 are disposed in the same battery compartment 10. In the case where the battery-swap vehicle 100 has a plurality of battery compartments 10, the battery-swap vehicle 100 can accommodate a greater number of batteries 20. For example, the battery-swap vehicle 100 has two battery compartments 10, and one of the two battery compartments 10 accommodates at least two batteries 20; or, each of the two battery compartments 10 accommodates at least two batteries 20.

[0185] Next, the battery compartment 10 of the battery-swap vehicle 100 is further introduced. Figure 8 Another schematic diagram of a battery-swap vehicle 100 according to the present application.

[0186] In one embodiment, Figure 8 As shown, the battery compartment 10 includes a first battery compartment 101 , and the first battery compartment 101 is arranged at the bottom 100a of the battery-swap vehicle 100 .

[0187] The bottom 100a of the battery swap vehicle 100 refers to the space near the vehicle floor. The bottom 100a of the battery swap vehicle 100 usually has a larger space, and the first battery compartment 101 arranged at the bottom 100a of the battery swap vehicle 100 can have a larger space accordingly, so as to accommodate a larger number of batteries 20. When each battery 20 can independently power the battery swap vehicle 100, it can provide users with more diverse battery swap capacity options, helping to improve user experience.

[0188] In one embodiment, see Figure 4 A protective plate 50 is provided on the end surface of the battery 20 arranged in the first battery compartment 101 facing away from the battery-swap vehicle 100 , and the protective plate 50 is at least part of the bottom plate of the battery-swap vehicle 100 .

[0189] Specifically, since the first battery compartment 101 is near the bottom plate of the battery-swap vehicle 100, by providing a protective plate 50 on the battery 20, on the one hand, it is possible to protect the battery 20 and avoid damage to the battery 20 when the bottom plate of the battery-swap vehicle 100 is scratched; on the other hand, the protective plate 50 can serve as part of the bottom plate of the battery-swap vehicle 100. In other words, the bottom plate of the battery-swap vehicle 100 adopts a modular bottom plate structure rather than an integrated bottom plate, and the bottom plate of the battery-swap vehicle 100 at the location of the first battery compartment 101 is the protective plate 50 of the battery 20. When the battery 20 is replaced in the battery-swap vehicle 100, this part of the bottom plate is replaced along with the replacement of the battery 20, so that the battery-swap vehicle 100 does not need to install the bottom plate again after the battery replacement, which simplifies the battery replacement steps, thereby reducing the time required for battery replacement, improving the battery replacement efficiency, and further improving the user experience.

[0190] In one embodiment, Figure 8 As shown, the battery compartment 10 includes a second battery compartment 102, and the second battery compartment 102 is arranged at the head 100b of the battery-swap vehicle 100.

[0191] The head 100b of the battery-swap vehicle 100 refers to the space in front of the battery-swap vehicle 100 in the first direction x, for example, the front 1 / 3 of the space. The structure of the head 100b of the battery-swap vehicle 100 is different from that of the bottom 100a. In order to adapt to the structure of the head 100b of the battery-swap vehicle 100, the shape and size of the second battery compartment 102 can be different from those of the first battery compartment 101, so that the second battery compartment 102 has a larger space and can accommodate a larger number of batteries 20, further improving the overall capacity of the battery-swap vehicle 100.

[0192] When the battery-swapping vehicle 100 is changing batteries, the mobile battery-swapping device in the battery-swapping station moves to the head 100b of the vehicle, removes the battery 20 in the second battery compartment 102, and then installs the battery 20 to be installed into the second battery compartment 102. When the battery-swapping vehicle 100 is changing batteries in the battery-swapping station, one mobile battery-swapping device can replace the batteries in different battery compartments one by one in sequence; or multiple mobile battery-swapping devices can replace the batteries in multiple battery compartments at the same time. For example, the battery swap vehicle 100 includes a first battery compartment 101 and a second battery compartment 102. The battery swap process of the battery swap vehicle 100 in the battery swap station can be: a mobile battery swap device first moves to the bottom 100a of the battery swap vehicle 100, completes the replacement of the battery 20 in the first battery compartment 101, and then moves to the head 100b of the battery swap vehicle 100 to replace the battery 20 in the second battery compartment 102; or it can be: the mobile battery swap device first moves to the head 100b of the battery swap vehicle 100, completes the replacement of the battery 20 in the second battery compartment 102, and then moves to the bottom 100a of the battery swap vehicle 100 to replace the battery 20 in the first battery compartment 102. Alternatively, the battery swap process of the battery swap vehicle 100 can be: the two mobile battery swap devices in the battery swap station move to the head 100b and the bottom 100a of the battery swap vehicle 100 respectively, and replace the batteries 20 in the first battery compartment 101 and the second battery compartment 102 at the same time.

[0193] In one embodiment, Figure 8 As shown, the battery compartment 10 includes a third battery compartment 103 , and the third battery compartment is arranged at the rear part 100c of the battery swap vehicle 100 .

[0194] The rear portion 100c of the battery-swap vehicle 100 refers to the space at the rear of the battery-swap vehicle 100 in the first direction x, for example, the rear 1 / 3 of the space. Similar to the second battery compartment 102, the shape and size of the third battery compartment 103 may also be different from the first battery compartment 101 to adapt to the structure of the rear portion 100c of the battery-swap vehicle 100, so that the battery-swap vehicle 100 can accommodate more batteries 20. The method of removing and replacing the battery in the third battery compartment 103 is similar to the method of removing and replacing the battery 20 in the second battery compartment 102, and is also achieved by a mobile battery-swap device, which will not be repeated here.

[0195] Figure 8In the illustrated embodiment, the battery-swap vehicle 100 has a first battery compartment 101, a second battery compartment 102, and a third battery compartment 103. In some other embodiments, the battery-swap vehicle 100 may include only the first battery compartment 101, or only the second battery compartment 102, or only the third battery compartment 103, wherein the number of the first battery compartment 101, the second battery compartment 102, and the third battery compartment 103 may be one or more. In other embodiments, the battery-swap vehicle 101 may also include any two battery compartments 10 among the first battery compartment 101, the second battery compartment 102, and the third battery compartment 103.

[0196] It should be understood that in the above-mentioned battery replacement scenario, the batteries 20 arranged in the first battery compartment 101, the second battery compartment 102 and the third battery compartment 103 can all independently power the battery replacement vehicle 100. Although the battery replacement vehicle 100 is equipped with multiple battery compartments 10 and multiple batteries 20, when replacing the battery, the user of the battery replacement vehicle 100 can selectively replace one or several batteries 20 in a battery compartment 10 according to his own driving needs, instead of having to replace all the batteries 20 in a battery compartment 10. For example, the battery replacement vehicle 100 includes a first battery compartment 101 and a second battery compartment 102, and the first battery compartment 101 is configured with a first battery and a second battery, and the second battery compartment 102 is configured with a third battery and a fourth battery. When replacing the battery, the user can choose to replace only the first battery; can also choose to replace the first battery and the second battery; can also choose to replace the first battery and the third battery; can also choose to replace the first battery, the second battery and the third battery, or choose to replace the first battery, the second battery, the third battery and the fourth battery.

[0197] Figure 8 In the illustrated embodiment, the first battery compartment 101, the second battery compartment 102, and the third battery compartment 103 all have regular shapes. In some other embodiments, the first battery compartment 101, the second battery compartment 102, and the third battery compartment 103 may be configured to have irregular shapes.

[0198] Based on this, by setting multiple battery compartments 10 at different positions of the battery swap vehicle 100, while increasing the capacity that the battery swap vehicle 100 can carry, the battery swap capacity that the user can choose is further enriched, effectively improving the flexibility of battery swapping of the battery swap vehicle 100.

[0199] Next, the multiple batteries 20 disposed in the same battery compartment 10 will be described in detail.

[0200] In one embodiment, the plurality of batteries 20 have the same shape.

[0201] Although the shapes of the multiple battery compartments 10 of the battery swapping vehicle 100 may be different, the shapes of the multiple batteries 20 arranged in the same battery compartment 10 may be the same. Arranging the multiple batteries 20 in the same battery compartment 10 to have the same shape facilitates the processing and large-scale production of the batteries 20, and helps to save the production cost of the batteries 20.

[0202] by Figure 8 Taking the first battery compartment 101 as an example, since the first battery compartment 101 is at the bottom 100a of the battery swap vehicle 100, it can be configured as a regular rectangular space. The multiple batteries 20 accommodated in the first battery compartment 101 can also be configured into a regular rectangular shape, or can also be configured into a regular cylindrical shape.

[0203] Fig. 9 FIG. 1 is another schematic diagram of the first battery compartment 101 according to an embodiment of the present application.

[0204] In another possible embodiment, the multiple batteries 20 disposed in the same battery compartment 10 have different sizes.

[0205] In the development process of the battery 20, in order to adapt to more models of vehicles, the size of the battery 20 may change. Taking the rectangular battery 20 as an example, the first-generation battery 20 and the second-generation battery 20 are different in at least one of the length, width, and height, and the second-generation battery 20 may have a smaller volume and higher capacity. For the battery-swap vehicle 100 that is already equipped with the first-generation battery 20, replacing the first-generation battery 20 with the second-generation battery 20 will obviously become an inevitable battery-swap demand.

[0206] Based on this, Fig. 9 In the illustrated embodiment, the bracket 11 is provided at a portion of the first battery compartment 101 to accommodate the need to accommodate multiple batteries 20 of different models. In some other embodiments, the first battery compartment 101 may be provided in an irregular shape, and the second battery compartment 102 and the third battery compartment 103 are similar, and will not be described in detail herein.

[0207] In one embodiment, the sizes of the multiple batteries 20 , the configuration of the electrical interfaces 50 , and the configuration of the water cooling interfaces 60 are all the same.

[0208] The size of the battery 20 refers to the size of the battery 20 in each direction of the three-dimensional space. For example, the size of a rectangular battery 20 refers to the length, width, and height of the battery 20. For another example, the size of a cylindrical battery 20 refers to the diameter and height of the battery 20. For another example, the size of an irregularly shaped battery 20 refers to the length of the battery 20 in the first direction x, the second direction y, and the third direction z.

[0209] The configuration of the electrical interface 50 includes at least one of the shape of the electrical interface 50 and the position of the electrical interface 50. The configuration of the water cooling interface 60 includes at least one of the shape of the water cooling interface 60 and the position of the water cooling interface 60.

[0210] By arranging multiple batteries 20 with the same size, electrical interface 50 settings, and water cooling interface 60 settings in the same battery compartment 10, it is helpful to mass-produce battery swap vehicles 100 and batteries 20, and help improve the production efficiency of battery swap vehicles 100. In addition, for battery swap stations, batteries 20 with different sizes, electrical interface 50 settings, and water cooling interface 60 settings will be stored in different locations in the battery swap station. Therefore, by arranging multiple batteries 20 with the same size, electrical interface 50 settings, and water cooling interface 60 settings in the same battery compartment 10, when the mobile battery swap equipment replaces the battery 20 in the same battery compartment 10, it only needs to take or place the battery 20 from a fixed position in the battery swap station, and does not need to move to multiple different positions in the battery swap station, which helps to simplify the battery swap process and improve the battery swap efficiency.

[0211] The specific structure of the battery 20 is further introduced below.

[0212] Please continue to see Figure 7 In one embodiment, the electrical interface 50 and / or the water cooling interface 60 are arranged on the end surface 203 of the battery 20 facing the battery-swap vehicle 100 .

[0213] The mobile battery swapping device usually operates under the battery swapping vehicle 100 during battery swapping, takes out the battery 20 in the battery compartment 10 of the battery swapping vehicle 100, and then lifts the battery 20 to be installed into the battery compartment 10. Therefore, by setting the electrical interface 50 and / or the water cooling interface 60 of the battery 20 on the end surface 203 of the battery 20, the electrical connection and water cooling connection between the battery 20 and the battery swapping vehicle 100 are automatically completed during the process of the battery 20 being lifted into the battery compartment 10, without the need for additional connection operations, further simplifying the battery swapping process of the battery swapping vehicle 100 and improving the battery swapping efficiency.

[0214] It should be understood that Figure 7 In the illustrated embodiment, the electrical interface 50 and the water cooling interface 60 are merely schematic. In some more specific embodiments, the electrical interface 50 is a connector of an electrical box of the battery 20, and the connector of the electrical box is used to output the electrical energy of the battery 20 to the battery swap vehicle 100, and the water cooling interface 60 is a connector of a water cooling box of the battery 20, and the connector of the water cooling box includes a liquid inlet and a liquid outlet, and is used to connect to the water cooling system of the battery swap vehicle 100.

[0215] In one embodiment, Figure 7As shown, in the second direction y, the electrical interface 50 and / or the water cooling interface 60 is arranged at the middle position of the battery 20 .

[0216] The electrical interface 50 and / or the water cooling interface 60 are set in the middle position of the battery 20 in the second direction y, so that after the battery 20 is installed in the battery compartment 10, the electrical interface 50 and / or the water cooling interface 60 are located on the central axis in the width direction of the battery swap vehicle 100, so that the weight of the battery 20 on both sides of the vehicle will not be affected by the electrical interface 50 and / or the water cooling interface 60, further improving the balance of the left and right sides of the battery swap vehicle 100, and helping to improve the safety performance of the battery swap vehicle 100.

[0217] In one embodiment, Figure 7 As shown, in the first direction x, the electrical interface 50 is eccentrically disposed on one side of the battery 20. That is, in the first direction x, the electrical interface 50 is located at a position other than the middle position.

[0218] Through the above arrangement, while ensuring the balance of the battery 20 in the second direction y, more space can be reserved in the first direction x for installing other functional modules of the battery 20, such as a battery management system (BMS). Thus, the space utilization rate inside the battery compartment 10 is improved.

[0219] In one embodiment, in the first direction x, a distance d4 between a geometric center of the electrical interface 50 and a geometric center of the battery 20 satisfies: 120 mm≤d4≤180 mm.

[0220] In one embodiment, Figure 7 As shown, in the first direction x, the water cooling interface 60 is disposed on the same side as the electrical interface 50 and is spaced apart from the electrical interface 50 .

[0221] Specifically, "the water cooling interface 60 is arranged on the same side of the electrical interface 50" means that the electrical interface 50 and the water cooling interface 60 are both arranged at a front or rear position of the battery 20 in the first direction x. For example, both are arranged near the front 1 / 2 in the first direction x. Setting the electrical interface 50 and the water cooling interface 60 on the same side helps save space in the battery compartment 10. At the same time, in order to avoid the impact of leakage at the water cooling interface 60 on the electrical interface 50, the electrical interface 50 and the water cooling interface 60 are spaced apart, which effectively avoids the electrical hazards caused by leakage of the water cooling interface 60 and improves the safety performance of the battery swap vehicle 100.

[0222] Fig.10 FIG. 2 is another schematic diagram of a battery 20 according to an embodiment of the present application.

[0223] In one embodiment, Fig.10As shown, in the first direction x, the water cooling interface 60 is arranged on a side opposite to the electrical interface 50 .

[0224] Specifically, “the water cooling interface 60 is disposed on a side opposite to the electrical interface 50” means that the electrical interface 50 and the water cooling interface 60 are respectively disposed at a front or rear position of the battery 20 in the first direction x. For example, the electrical interface 50 is disposed at a position close to the front 1 / 2 in the first direction x, and the water cooling interface 60 is disposed at a position close to the rear 1 / 2 in the first direction x.

[0225] In one embodiment, the electrical interface 50 and the water cooling interface 60 are the same integrated interface.

[0226] Specifically, the electrical interface 50 and the water cooling interface 60 are sealed and electrically isolated, and the two can be integrated into an integrated interface. Through the integrated interface, electrical connection and water cooling connection can be achieved simultaneously during the installation of the battery 20 into the battery compartment 10. By configuring the electrical interface 50 and the water cooling interface 60 into an integrated interface, redundant and useless interfaces can be saved, and the space of the battery 20 and the battery compartment 10 occupied by the redundant interfaces can be saved. At the same time, when the battery 20 is docked with the battery-swap vehicle 100, it is originally necessary to align the two interfaces. By setting an integrated interface, the difficulty of docking the battery 20 with the battery-swap vehicle 100 is also reduced, which helps to improve the battery-swap efficiency of the battery-swap vehicle 100.

[0227] Please continue to see Figure 7 and Fig.10 In one embodiment, a groove 2031 is provided on the end surface 203 of the battery 20 facing the battery-swap vehicle 100 , and the electrical interface 50 and / or the water-cooling interface 60 are provided in the groove 2031 .

[0228] The groove 2031 extends along the first direction x on the end surface 203 of the battery 20. The groove 2031 may extend in the first direction x to a wall (eg, Fig.10 ), or partially extended (as shown Fig. 9 As shown). By providing a groove 2031 on the end face 203 of the battery 20, the electrical interface 50 and the water cooling interface 60 can be provided in the groove 2031 without protruding from the end face 203 of the battery 20, thereby saving the internal space of the battery 20 and the battery compartment 10. In addition, the provision of the groove 2031 destroys the flatness of the end face 203 of the battery 20 facing the battery swap vehicle 100, so that the electrical interface 50 and / or the water cooling interface 60 can be roughly positioned through the groove 2031 during the process of the battery 20 being lifted into the battery compartment 10 by the mobile battery swap device.

[0229] Next, the multiple batteries 20 disposed in different battery compartments 10 are introduced in detail.

[0230] In one embodiment, the plurality of batteries 20 have at least two different shapes.

[0231] As mentioned above, the shapes of different battery compartments 10 may be different, especially the second battery compartment 102 and the third battery compartment 102, which are respectively arranged at the head 100b and the tail 100c of the battery swap vehicle 100. In order to accommodate a larger number of batteries, irregularly shaped battery compartments 10 can be designed according to the actual free space of the battery swap vehicle 100. In the case where the shape of the battery compartment 10 is irregular, regular and identical batteries 20 can be used as described above. At this time, the size of each battery 20 can be designed to be smaller to make full use of the space in the battery compartment 10. Alternatively, a battery 20 with a corresponding irregular shape can be designed according to the shape of the battery compartment 10. In other words, special-shaped batteries can be arranged in an irregularly shaped battery compartment 10.

[0232] In one embodiment, the plurality of batteries 20 have at least two different sizes. Specifically, the batteries 20 disposed in different battery compartments 10 may have different sizes, or the batteries 20 disposed in the same battery compartment 10 may have different sizes.

[0233] For example, the battery swap vehicle 100 includes a first battery compartment 101 and a second battery compartment 102, and the first battery compartment 101 and the second battery compartment 102 both have regular shapes, and the batteries 20 disposed therein may also have regular shapes, for example, rectangular shapes, but the rectangular batteries 20 disposed in the first battery compartment 101 and the rectangular batteries 20 disposed in the second battery compartment 102 are different in length, width or height. Examples of multiple batteries 20 of different sizes disposed in the same battery compartment 10 have been introduced above and will not be repeated here.

[0234] In one embodiment, the plurality of batteries 20 have at least two different shapes. Specifically, the batteries 20 disposed in different battery compartments 10 may have different shapes, or the batteries 20 disposed in the same battery compartment 10 may have different shapes.

[0235] For example, the battery swap vehicle 100 includes a first battery compartment 10, which has a regular shape. Among the multiple batteries 20 arranged therein, some may be rectangular batteries 20, and the rest may be cylindrical batteries 20. Specifically, the batteries 20 are arranged along the first direction x, and in the second direction y, the length of the rectangular battery 20 and the height of the cylindrical battery 20 may be equal.

[0236] In one embodiment, batteries 20 of different shapes are disposed in different battery compartments 10 .

[0237] Fig.11This is another schematic structural diagram of a battery-swap vehicle 100 according to an embodiment of the present application. Fig.11 In the illustrated embodiment, the battery swapping vehicle 100 includes a first battery compartment 101 and a third battery compartment 103. The first battery compartment 101 is in the shape of a regular rectangular parallelepiped, while the third battery compartment 103 is in an irregular shape, specifically, in the shape of an L. The multiple batteries 20 disposed in the first battery compartment 101 may all be rectangular parallelepiped batteries 20, and the multiple batteries 20 disposed in the third battery compartment 103 may all be L-shaped batteries 20.

[0238] It should be understood that the multiple rectangular batteries 20 disposed in the first battery compartment 101 may have the same or different sizes, and the multiple L-shaped batteries 20 disposed in the third battery compartment 103 may have the same or different sizes.

[0239] In one embodiment, the multiple batteries 20 have at least two different full-charge capacities. Specifically, the full-charge capacities of the batteries 20 installed in different battery compartments 10 may be different, or the full-charge capacities of the batteries 20 installed in the same battery compartment 10 may be different. The full-charge capacities of the batteries 20 of different shapes or sizes may be different, or the full-charge capacities of the batteries 20 of the same shape and / or size may be different.

[0240] Among them, full charge refers to the charge when the battery is normally charged until the SOC reaches 100%.

[0241] In one embodiment, the battery-swap vehicle 100 includes a power supply circuit, which includes multiple access points; batteries 20 with different full charges are connected to different access points.

[0242] Specifically, batteries 20 with different full charges can be respectively configured with independent power supply circuits to enable the batteries 20 to independently power the battery swapping vehicle 100. When multiple batteries 20 of the battery swapping vehicle 100 have different full charges, multiple batteries 20 can be connected in series to provide a higher voltage when the battery swapping vehicle 100 requires high voltage; or multiple batteries 20 can be connected in parallel, and multiple batteries 20 with different full charges can power the battery swapping vehicle 100 at the same time.

[0243] In one embodiment, the power supply circuit is configured to be able to adjust the series-parallel relationship of multiple batteries 20. Specifically, the power supply circuit may include multiple switches, and the series-parallel relationship of multiple batteries 20 is adjusted by controlling the multiple switches. Thus, the series-parallel relationship of multiple batteries 20 can be adjusted by the power supply circuit, so that the battery-swap vehicle 100 can adapt to the different power requirements of users in different scenarios.

[0244] In one embodiment, the multiple batteries 20 have at least two different energy densities. Specifically, the multiple batteries 20 disposed in the same battery compartment 10 may have different energy densities, or the multiple batteries 20 disposed in different battery compartments 10 may have different energy densities.

[0245] For example, the battery-swap vehicle 100 includes a first battery compartment 101 and a second battery compartment 102. The multiple batteries 20 disposed in the first battery compartment 101 have different energy densities, and the multiple batteries 20 disposed in the second battery compartment 102 have different energy densities. The energy density of a battery 20 in the first battery compartment 101 and the energy density of a battery 20 in the second battery compartment 102 may be the same or different. For another example, the multiple batteries 20 disposed in the first battery compartment 101 have the same energy density, which has a first energy density, and the multiple batteries 20 disposed in the second battery compartment 102 have the same energy density, which has a second energy density, and the first energy density is not equal to the second energy density.

[0246] On the one hand, batteries with low energy density have lower costs, making battery replacement costs lower; on the other hand, under the same volume, batteries 20 with low energy density are usually heavier, resulting in increased energy consumption for users to travel. Batteries 20 with high energy density are the opposite, with higher costs but lower energy consumption. Therefore, by providing batteries 20 with different energy densities in the battery replacement vehicle 100, users can flexibly select the battery 20 that needs to be replaced according to their own needs, providing users with more diverse battery replacement solutions.

[0247] In one embodiment, the plurality of batteries 20 have at least two different chemical systems. The chemical systems of the batteries include lithium-ion batteries, sodium-ion batteries, magnesium-ion batteries, lithium metal batteries, etc. Lithium-ion batteries can be further divided into lithium cobalt oxide batteries, lithium iron phosphate batteries, ternary nickel-cobalt-manganese batteries, etc. according to the negative electrode material.

[0248] Batteries 20 of different chemical systems usually have different capacities, in other words, different fully charged capacities, when the volume is constant. Therefore, there is no need to change the structure of the battery compartment 10 of the battery swap vehicle 100. By providing batteries 20 of different chemical systems, the battery swap vehicle 100 can have a variety of capacity options.

[0249] In one embodiment, at least one of the full charge capacity, energy density, and electrochemical system of batteries 20 of different shapes is different.

[0250] The present application also provides a method for preparing a battery swap vehicle 100, the method comprising: providing a battery compartment 10. The battery compartment 10 is disposed in the battery swap vehicle 100, and the battery compartment 10 is used to accommodate a plurality of batteries 20, each battery 20 being able to independently power the battery swap vehicle 100.

[0251] In addition, the present application also provides a battery 20 applied to a battery swap vehicle 100, and the battery 20 has all the features of the aforementioned battery 20, which will not be repeated here.

[0252] To sum up, the battery-swap vehicle 100 provided in the present application can be compatible with batteries 20 of various connection methods, shapes, sizes, full charges, and chemical systems through different designs and combinations of the battery compartment 10 and the battery 20. This allows users of the battery-swap vehicle 100 to flexibly and diversely choose suitable battery-swap solutions according to their own driving needs or power needs when swapping batteries at a battery-swap station, thereby greatly optimizing the user experience.

[0253] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
