Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a fast-swapping hydrogen-electricity replenishment system, its electrical equipment, and a battery-swapping vehicle. Background Technology

[0002] Against the backdrop of dual carbon emissions, the electrification of transportation vehicles is rapidly developing, with various types of vehicles emerging on the market, including pure electric (charging and battery swapping), hybrid (oil-electric hybrid), and hydrogen fuel cell power. Existing pure electric and hydrogen fuel cell vehicles operate independently in terms of technology. For example, existing hydrogen fuel cell vehicles typically integrate the fuel cell with the vehicle itself, thus preventing resource sharing to reduce operating costs. Therefore, it is necessary to develop a rapidly replaceable, detachable, independent hydrogen fuel cell power supply system. Compatible with existing battery swapping interfaces, this system would allow existing battery-swapping heavy-duty trucks to be equipped with hydrogen fuel cell power modules, thus becoming hydrogen-powered vehicles. Simultaneously, it addresses the issue of directly replacing mature pure battery modules when no hydrogen fuel cell power modules are available. Through "vehicle-hydrogen separation" and "hydrogen-electric complementarity," it reduces customer purchase costs, mitigates vehicle technology risks, alleviates the pressure on hydrogen refueling infrastructure construction, and conserves social resources.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1 to 4 As shown, this utility model embodiment provides a fast-swap hydrogen-electricity replenishment system 100 for providing power to electrical equipment or battery-swapping vehicles with a battery swapping base 500. The battery swapping base 500 can be a battery swapping base installed on the frame 62 of a new energy battery-swapping vehicle, or a bracket (not shown) installed on or beside the electrical equipment. The fast-swap hydrogen-electricity replenishment system 100 generates electricity by burning hydrogen fuel internally, ultimately providing power to the electrical equipment or battery-swapping vehicle. When hydrogen fuel is insufficient, the fast-swap hydrogen-electricity replenishment system 100 can be completely replaced or replenished with hydrogen fuel to achieve continuous power supply. Furthermore, as... Figure 5 As shown, a traditional battery swapping unit 500 can be selectively installed on the battery swapping base 500. Therefore, the fast-swap hydrogen-electricity replenishment system 100 conforming to this utility model makes the selection scenarios for new energy more diversified. That is to say, the fast-swap hydrogen-electricity replenishment system 100 conforming to this utility model does not require changes to existing battery swapping new energy vehicles or electrical equipment with battery swapping base 500, and has a good foundation for promotion. It is worth noting that, for ease of introduction, Figure 1 and Figure 2 The quick-change hydrogen-electricity replenishment system 100 in this application omits the shell covering the outer periphery of the main body 10. Although the shell can play a role in dust and water protection, it is not a core feature of this application. At the same time, this application does not elaborate on conventional technical means such as the connection method of pipelines and lines that are easy to understand.

[0031] Please refer to Figures 1 to 4The quick-swap hydrogen-electric recharge system 100 conforming to the first embodiment of this utility model is used to be detachably installed on the battery swapping support 500 on the frame 62 of a new energy vehicle. The battery swapping support 500 is provided with a first electrical connector 52 with the interface facing upward. The quick-swap hydrogen-electric recharge system 100 includes a box-shaped, frame structure body 10 and a second electrical connector 22 provided at the bottom of the body 10 and matched with the first electrical connector 52. The body 10 includes a battery swapping docking part 110 for installing the second electrical connector 22. The body 10 is provided with a fuel cell system 32, a fuel supply system 31, and a fuel storage device 30 (e.g., a hydrogen storage tank) located on the upper part of the fuel cell system 32 and the fuel supply system 31, which are fixedly installed on the battery swapping docking part 110. The fuel cell system 32 is electrically connected to the second electrical connector 22. The fuel cell system 32 generates electrical energy through a chemical reaction with the fuel in the fuel storage device 30. This electrical energy is then transmitted to the power motor (not shown) of the new energy vehicle via the second electrical connector 22, generating kinetic energy to propel the new energy vehicle. In some embodiments, for ease of installation, the battery swapping docking part 110 and another part of the main body 10 can be detachably connected. That is, the main body 10 can be divided into an upper frame and a lower frame, and the two can be detachably connected as one unit by bolts or other means. In other embodiments, the main body 10 of the quick-swap hydrogen-electricity replenishment system 100 is not limited to a frame form; for example, it can also be a box form, which will not be elaborated here.

[0032] Furthermore, the main body 10 is also fixedly equipped with a fuel supply controller 33 and a reactor controller (unlabeled), such as... Figure 1 and Figure 2 As shown, the aforementioned controller can be placed on the side of the main body 10. Obviously, depending on the space arrangement requirements, in other embodiments, the controller can also be placed on the battery swapping docking part 110 at the bottom of the main body 10.

[0033] Preferably, the fast-swap hydrogen-electric refueling system 100 further includes a power battery 20 within its main body 10. The power battery 20 is located on one side of the fuel storage device 30 and is electrically connected to the second electrical connector 22. The power battery 20 can be positioned below, above, or on any side of the fuel storage device 30, as needed. In some embodiments, the power battery 20 can consist of two or more battery modules, distributed around the fuel storage device 30, which will not be elaborated further here. In this invention, the power battery 20 acts as a reservoir. When the new energy vehicle needs high-power acceleration or hill climbing, the power battery 20 can work with the fuel cell system 32 to power the motor of the battery-swapping vehicle. When the new energy vehicle is going downhill, decelerating, or braking, the power battery 20 can also recover the vehicle's kinetic energy, further achieving the goal of energy conservation and emission reduction. In some embodiments, the fuel cell system 32 is electrically connected to the second electrical connector 22, and supplies power directly to the electrical equipment or battery-swapping vehicle through the second electrical connector 22. At the same time, the fuel cell system 32 is also electrically connected to the power battery 20. The advantage of this design is that excess electrical energy generated by the fuel cell system 32 can be stored in the power battery 20. When the new energy vehicle is climbing a hill or requires a large power drive, the fuel cell system 32 and the power battery 20 can simultaneously provide power to the drive system of the new energy vehicle.

[0034] Preferably, the power battery 20 is equipped with a first thermal management system (not shown), and the battery swapping docking part 110 is also equipped with a first coolant quick-connect connector 43 communicating with the first thermal management system. The battery swapping receiving seat 500 is equipped with a third coolant quick-connect connector 53 that matches the first coolant quick-connect connector 43. The fuel cell system 32 includes a hydrogen fuel cell reactor, a fuel supply system 31, and a second cooling device (not shown). The battery swapping docking part 110 is also equipped with a second coolant quick-connect connector 44 communicating with the second cooling device, and the battery swapping receiving seat 500 is equipped with a fourth coolant quick-connect connector 54 that matches the second coolant quick-connect connector 44. By setting the third coolant quick-connect connector 53 and the fourth coolant quick-connect connector 54, at least a part of the refrigeration system (not shown) can be installed on the frame 62 or the front 61 of the new energy vehicle, thereby making the space utilization rate within the quick-swap hydrogen-electricity replenishment system 100 higher. Specifically, the first thermal management system inside the power battery 20 transfers heat through the coolant via the first coolant quick connector 43 and the third coolant quick connector 53 to the refrigeration system on the new energy vehicle for heat dissipation. This can control the temperature of the power battery 20 and prevent thermal runaway. Similarly, the refrigerant flowing through the second coolant quick connector 44 and the fourth coolant quick connector 54 can perform thermal management on the fuel cell system 32, or reuse and recover the waste heat generated by the fuel cell system 32. For example, in winter, the waste heat generated by the fuel cell system 32 can be utilized through heat exchange in the refrigeration system to warm the cabin or heat and insulate the power battery 20.

[0035] In some embodiments, the second cooling device includes a radiator and a fan (not shown) disposed on the periphery or top of the main body. The casing of the quick-swap hydrogen-electric recharge system 100 also has air inlets and outlets (not shown). This design is primarily intended to address the significant heat generated by the fuel cell system 32, which cannot be adequately cooled by the aforementioned cooling system alone. It also considers that during the operation of the new energy vehicle, the quick-swap hydrogen-electric recharge system 100 located on the battery swapping base 500 provides better ventilation and heat dissipation. Obviously, the aforementioned radiator and fan can also be associated with the first thermal management system. During the charging process of the power battery 20, excess heat can be dissipated into the atmosphere. By using conventional methods such as shut-off valves and three-way valves (not shown), the selective control of the pipeline's opening and closing can be achieved, thereby realizing thermal management within the quick-swap hydrogen-electric recharge system 100.

[0036] In order to achieve rapid installation and disassembly of the quick-change hydrogen-electricity replenishment system 100, in the first embodiment, the quick-change hydrogen-electricity replenishment system 100 further includes a gripping part 13 located on the top of the body 10, so as to realize the top-mounted installation and disassembly of the quick-change hydrogen-electricity replenishment system 100. In other embodiments, the quick-change hydrogen-electricity replenishment system 100 can also be disassembled and assembled by side gripping. In this case, it is only necessary to set the gripping part on any side of the body 10.

[0037] Preferably, such as Figure 5 As shown, in one application scenario of the first embodiment of the quick-swap hydrogen-electric refueling system 100, a fuel replenishment interface 103 is provided on one side of the main body 10. In actual use, it is preferable to drive the new energy vehicle to an energy replenishment station to replace the entire quick-swap hydrogen-electric refueling system 100 when the fuel in the quick-swap hydrogen-electric refueling system 100 is insufficient. However, in some scenarios, such as when the new energy vehicle is far from the energy replenishment station, the driving range can also be increased by refueling the quick-swap hydrogen-electric refueling system 100 through the fuel replenishment interface 103. Obviously, the fuel replenishment interface 103 is connected to the fuel storage device 30. For example, a hydrogen refueling port is provided at the fuel replenishment interface 103, and the hydrogen refueling port is connected to the injection port of the fuel storage device 30.

[0038] In another application scenario of the first embodiment, the fuel storage device 30 is detachably installed inside the body 10. The body 10 has an installation port 120 on one side for the fuel storage device 30 to enter and exit. The installation port 120 is closed during the operation of the new energy vehicle. When the fuel in the fuel storage device 30 is insufficient, the fuel storage device 30 can be replaced separately through the installation port 120, making maintenance more convenient.

[0039] Furthermore, to enable rapid assembly and disassembly of the quick-swap hydrogen-electric refueling system 100 with the battery-swapping vehicle or electrical equipment, the battery-swapping receiving base 500 is equipped with a locking device 56 and a guide positioning post 51. The battery-swapping docking part 110 is equipped with a locking part 112 that matches the locking device 56 and a guide positioning part 113 that matches the guide positioning post 51. Preferably, the guide positioning part 113 on the battery-swapping docking part 110 extends vertically, thereby enabling the guide positioning post 51 to complete the guiding and positioning when the quick-swap hydrogen-electric refueling system 100 is installed vertically onto the battery-swapping receiving base 500. Preferably, to ensure accurate matching between the first electrical connector 52 and the second electrical connector 22, the first coolant quick-connect connector 43 and the third coolant quick-connect connector 53, and the second coolant quick-connect connector 44 and the fourth coolant quick-connect connector 54, the battery-swapping receiving base 500 is also equipped with a precision guide post 55. The battery swapping docking part 110 of the main body 10 is also provided with a precision guide hole 114. These technical means are the same as those of the existing battery swapping battery 900. It is worth mentioning that the positions of the locking device 56 and the locking part 112 are obviously interchangeable. The position of the guide positioning post 51 can obviously be set in the battery swapping docking part 110, and the guide positioning part 113 can be set on the battery swapping receiving seat 500. The interchange of positions does not affect the quick assembly and disassembly of the quick-change hydrogen-electricity replenishment system 100 conforming to this utility model with the battery swapping vehicle or electrical equipment. It will not be described in detail here.

[0040] Re-entry Figure 6 As shown, in the second embodiment of this utility model, the fast-swap hydrogen fuel cell recharge system 100 is mounted from bottom to top onto the battery swapping support 500 on the vehicle frame 62. For example, in existing chassis battery swapping modes, only the battery swapping system needs to be replaced with the fast-swap hydrogen fuel cell recharge system 100 conforming to this utility model to enable the use of hydrogen fuel cells in battery swapping vehicles. Figure 6 The guiding system and locking mechanism are omitted in the second embodiment. On one hand, the guiding system and locking mechanism can refer to the first embodiment; on the other hand, they can draw on existing chassis battery swapping technology, and will not be elaborated further here. In the second embodiment, the main body 10 is equipped with a fuel cell system 32, a fuel storage device 30, and a second electrical connector 22. The frame 62 is equipped with a first electrical connector (not shown) that is mutually matched with the first electrical connector 22. The power battery 20 can be located above the fuel cell system 32, or below the fuel cell system 32, or on the left or right sides. That is to say, the positions of the power battery 20 and the fuel supply system 31 are interchangeable. In other words, in the second embodiment, apart from the fuel storage device 30 being located on both sides of the main body, the specific positions of the power battery 20, fuel supply system 31, controller, etc., within the main body 10 are not particularly limited.

[0041] The first and second embodiments of this utility model use a battery-swapping heavy-duty truck with a frame 62 as an example. Obviously, the fast-swapping hydrogen-electric recharge system 100 provided by this utility model is also applicable to other new energy vehicles that use battery swapping for recharge. For example, when used in a battery-swapping car, only a miniaturized fast-swapping hydrogen-electric recharge system 100 needs to be selected, referring to the second embodiment. In some electrical equipment, such as situations requiring temporary power supply, the fast-swapping hydrogen-electric recharge system 100 can be used as a temporary generator by placing the battery swapping receiving base 500 on the electrical equipment or around the electrical equipment. Compared to traditional generators using fuel, this is more environmentally friendly and utilizes chemical energy more fully.

[0042] The fast-swap hydrogen-electricity replenishment system 100 conforming to this utility model separates the fuel cell from the electrical facilities, and is well compatible with existing new energy battery-swapping vehicles and electrical equipment operating in the battery-swapping mode. It is more efficient in the later maintenance and asset management, overcomes the existing technical problems of difficulty in promoting hydrogen energy, and helps to achieve carbon neutrality. It has good application prospects. Obviously, the hydrogen energy in this utility model is not limited to pure hydrogen. Other hydrogen-based energy sources can also be used equivalently. For example, methanol can be stored in the fuel storage device 30 and fuel can be supplied to the fuel cell system 32 through the fuel supply system 31 to achieve the purpose of this utility model. Further details are omitted.

[0043] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
