Description

Fuel cell integrated systems and vehicles

Technical field

This application relates to the technical field of fuel cell vehicles and their supporting energy systems, and in particular to a fuel cell integrated system. The application also relates to a vehicle using the fuel cell integrated system.

Background technique

Hydrogen fuel cells have been widely used in the automotive field. In order to reduce the complexity of vehicle layout design, assembly and maintenance, fuel cell systems are often supplied in the form of powertrains, that is, the stack and its associated air vapor are The system, hydrogen subsystem, cooling subsystem and control module are pre-integrated and assembled, and then assembled and connected to the entire vehicle. However, due to the differences in the internal space and body structure components of different models, as well as the large volume and low integration of components, it is difficult for the same fuel cell design to be compatible with different models. To this end, existing technical solutions in this field have been explored and applied from the following two aspects:

1. Optimize the system integration solution. Through partitioning and hierarchical layout, setting up integrated frame connections, surrounding layout with the stack as the center, rationally setting interfaces, modular integrated layout, etc., we can achieve design goals such as effective use of space, reduction of system volume, and improvement of assembly convenience;

2. Part function integration. By merging some parts and reducing the number of parts casings or interfaces between them, the space occupied is reduced, thereby reducing the volume of the entire fuel cell system, such as merging multiple controllers into an all-in-one controller, combining the intercooler and the intensifier Humidifier for direct integration, etc.

However, the existing technical solutions described above still have the following problems:

1. Problems in optimizing system integration solutions: The system is still composed of multiple parts. The shape interfaces of each part are different, making it difficult to maximize the use of the layout space. Reasonable gaps still need to be reserved between parts, and necessary brackets are needed to connect each part combination. , pipelines, wire harnesses, optimized layout without effective and reasonable integration processing, can only shorten the path or simplify the structure, cannot reduce the number of parts, nor eliminate space occupation, etc., so its effect on improving space utilization is limited. Moreover, it will bring problems such as high cost, complex assembly, low system efficiency, and poor reliability.

2. Problems with part function integration: Partial part integration only eliminates the gaps between several parts without considering the needs of the entire system assembly. Moreover, the integrated component structure is larger than a single part and requires higher layout space. , resulting in a more restricted layout. If the integration structure is unreasonable, it will cause other peripheral parts to take up more space when matching, which is not conducive to improving the integration of the entire system. In addition, the merger of some parts is still limited, and from a system perspective It can also be expanded to a greater extent of parts integration, so this form of integration is insufficient and not combined with the system layout plan.

Therefore, how to optimize the structural layout of the fuel cell system and improve the structural integration of its components is a matter for those skilled in the art. Important technical issues that members currently need to solve.

The structural layout and integration degree enable the fuel cell integrated system to form an integrated high-integration component structure.

It should be understood that all high and low voltage controllers in the fuel cell integrated system are integrated into the controller assembly 110 in the form of control modules, such as DC converters, air compressor controllers, water pump controllers, and fuel cell system controllers. etc., this type of modular integrated design solution has been reflected in relevant patents, and those skilled in the art can use any conventional technical means to help realize the solution. The rest of this article involving conventional assembly and integration of components and conventional functions can be understood and implemented with reference to existing technologies, and will not be described again here.

Further, the housing of the air compressor 106 and the lower box 403 have an integrated structure.

Referring to Figure 11, in actual applications, the housing and lower box 403 of the air compressor 106 can also be designed as a split structure, that is, a split integrated controller housing 1001 and a split air compressor motor as shown in Figure 11 Shell 1002, and then the two shells are reliably assembled through bolts or other detachable connectors, so that corresponding components can be disassembled and assembled when necessary to meet operational requirements such as component maintenance and replacement.

Furthermore, the cooling pipeline of the integrated controller assembly 110 is connected in parallel with the cooling pipeline of the air compressor 106 . In this way, the adaptation effect and operating efficiency of the cooling pipeline of the integrated controller assembly 110, the cooling pipeline of the air compressor 106, and related hydraulic devices such as the water pump 107 can be further optimized, and the corresponding number of components and component structure layout can be further streamlined. , thereby correspondingly improving the integration degree of the cooling system components of the fuel cell integrated system.

On the other hand, the stack assembly 111 includes several stacked stack modules 901 , and the three-cavity interfaces of the stack modules 901 are symmetrically arranged on both sides of the end plates of the stack modules. The stacked arrangement structure allows workers to flexibly adjust the number of stack modules according to working conditions.

In addition, the electrical connection between the stack assembly 111 and the integrated controller assembly 110 is achieved through a flexible copper bar. Flexible copper bars are used to directly connect the stack component 111 to the integrated controller component 110 and related high-voltage electrical matching parts. There is no need to arrange connectors and cables accordingly, which greatly reduces the space occupied by the electrical connection structure and integrates the overall structure of the system components. The accuracy can be further improved, making assembly and connection simpler and easier.

In order to facilitate understanding of this solution, the specific structural design of the fuel cell integrated system in this application will be described below in conjunction with the specific component layout.

According to the shape and interface restrictions of the fuel cell system in the vehicle application environment, while comprehensively considering the system architecture and component composition, the positional relationship of the main parts is determined through continuous combination and splicing, preliminary connection of pipelines and wiring harnesses, and the design of structural parts such as brackets are reserved. space, as the basis for the next detailed design. In order to ensure deep integration, this plan divides the overall layout space into three layers. The top layer is the stack component 111, and the middle layer is the integrated controller component 110. In order to better realize the stack dielectric connection, and the remaining accessories are arranged in 2 areas. The bottom area includes an air compressor 106, a water pump 107, a heat exchanger 108, an intercooler 109, an air bypass valve 115, and an air drain valve 116; the side area includes an ejector 101 , hydrogen proportional valve 102, thermostat 103, anode water separator 104, hydrogen exhaust valve 105, air back pressure valve 112, cathode water separator 113, air inlet valve 114. Setting the integrated controller component 110 in the middle layer is more conducive to the integration of control, structure, thermal management and high-voltage connections to achieve integrated design goals.

According to the relative positional relationship between the integrated controller component 110, the stack component 111, the air compressor 106, and the water pump 107, the layout of each control module inside the controller is designed in the reserved integrated controller component housing 202 to meet the requirements of the controller. The requirements for the position of the high-voltage electrical interface with the controlled device. More specifically, there are laminated busbars 301, DCF (distributed coordination function) control driver integrated PCB board 302, and DCF dual-phase integrated SiC module 303 arranged inside the integrated controller component. , integrated parallel water channel design 304, three-in-one motor control drive PCB board 305, air compressor SiC module 306, air compressor three-phase AC filter 307, two-phase magnetic integrated boost power inductor 308, integrated bus DC_Link (DC support) capacitor 309, fuel cell system management controller FCU (fan coil unit) 310, and relay 311, which have the characteristics of reasonable module division, good cooling effect of shared parallel water channels, divided shell structure isolation, and compact structure.

After the controller is designed and the relative positions of the parts have been basically determined, the casing of the stack assembly 111, the casing of the integrated controller assembly 110, and the motor casing of the air compressor 106 can be merged to reduce the relative distance and cancel the connection. Using brackets, taking into account the assembly process requirements, the overall structure is assembled through the top cover 401, the upper box body 402 and the lower box body 403. The shell structure When designing the structure, ensure that the high-voltage electrical interface of the integrated controller component designed in the previous step is reserved. At the same time, the installation and connections of the air compressor motor 502, air compressor outlet pump head 501, air compressor inlet pump head 503, etc. need to be taken into consideration to ensure The feasibility of processing and assembly, etc.; in addition, the heat exchanger 108 is directly connected to the intercooler 109 and the air compressor 106, eliminating the transition brackets and pipelines between parts, improving system integration and reducing installation and Maintenance costs.

On the basis of the integrated mechanical structure, a detailed design of thermal management is carried out. First, a detailed design of the cooling flow channel is carried out inside the casing, and the cooling flow channel 605 of the integrated controller component and the cooling flow channel 604 of the air compressor motor are carried out. Cavity design, multiple cooling cavities are connected in sequence through flow channels at the same time. After the coolant enters through the integrated controller component coolant inlet 602, it flows into the integrated controller component 110 and the air compressor motor 502 at the same time, and finally flows through the integrated controller component 110 and the air compressor motor 502 respectively. The coolant outlet 601 of the integrated controller component and the coolant outlet 603 of the air compressor motor flow out, which is more convenient and efficient than the existing dispersed arrangement that requires connecting pipelines and has multiple sets of inlets and outlets. Next, the air efficient utilization area is designed. The external air enters through the air compressor inlet interface 703, is compressed in the air compressor 106 and becomes a high-temperature gas. After that, it enters the heat exchanger 108 and interacts with the low-temperature gas flowing out of the stack air outlet interface 702. The air undergoes heat exchange. After the high-temperature gas further passes through the intercooler 109, it enters the stack assembly for reaction through the stack air inlet interface 701. The low-temperature gas enters the expander end of the air compressor 106 and is discharged through the tail air outlet interface 704. In addition, in order to control the gas flow at the expander end of the stack assembly 111 and the air compressor 106, a bypass valve 115 and a drain valve 116 are provided. This solution achieves effective utilization of air heat in a highly integrated form and is beneficial to improving expansion. machine energy recovery and improve system efficiency.

After that, a detailed design of the high-voltage electrical connection is carried out. Taking the connection between the stack component 111 and the integrated controller component 110 as an example, the entire connection relationship is completely realized inside the integrated frame structure. The stack component 111 connects the high-voltage output positive and negative electrode copper bars 802 and 805 goes deep into the integrated controller component 110. In order to facilitate assembly and connection, it is connected to the positive relay 803 and the negative relay 804 in the integrated controller component through two flexible transfer copper bars 801 and 806. The connection relationship is completely realized inside the shell. , without cables and connectors. The three-phase high-voltage connection structure of the air compressor 106, the water pump 107 and the integrated controller assembly 110 is similar to this. Only the positions are different and will not be described again.

Finally, the layout plan of other components in the system is refined to further optimize the connection form and fully utilize the space, further reduce the system volume and improve the integration level. Specific to the internal layout plan of the stack assembly, the stack is first integrated into a standard stack module 901 according to space constraints. Its length and width are designed according to the layout space structure restrictions. The three-cavity interfaces 904 are distributed on both sides of the end plate. When docking, according to External docking relationships are selected and combined. In addition, this solution adopts the form of two standard stack modules 901 stacked one above the other. The anode current collector plate 902 and cathode current collector plate 903 of the two stack modules 901 are connected in series through the stack connection busbar 905. The integrated form of the stack component avoids the impact of a large number of high-power stack sections and large size, and the system is compact, highly integrated, and the stack has flexible scalability.

Through the above design scheme, an integrated fuel cell integrated system design scheme under deep integration is finally realized, achieving the design goals of small system equipment, low cost, high reliability and convenient application, and a highly integrated scheme compatible with different models of vehicles. Arrangement requirements.
