Description
Technical Field
The invention belongs to the technical field of fuel cells, and particularly relates to a vehicle fuel cell system with an integrated controller and a vehicle.
Background
The fuel cell system is generally composed of a plurality of scattered parts due to the structural requirement, the arrangement form and the structure are complex, along with the gradual thinning of the vehicle scene of the fuel cell and the gradual maturity of the development of the parts, higher requirements are put forward on the integration level of the system, and the integrated system scheme with smaller system volume, higher power density and less component number has more market competitiveness in the aspects of application convenience, cost and reliability. In the aspect of integrated design, integration of a plurality of distributed parts is one of main technical means, wherein the integration and combination of multiple controllers can greatly simplify the connection of wire harnesses and cooling pipelines, and the improvement of integration level is more favorable.
At present, often adopt 2 kinds of arrangement forms in the design, the controller that unifys more is dispersed to be arranged and is unifyed the controller independent layout more, specifically is: the fuel cell system controller is integrated with the controller, such as a water pump and controller, an air compressor and controller and the like, and is applied in batches, and the multiple controllers are combined into one controller, such as a fuel cell system controller, a boosting DC/DC, a PDU (protocol data Unit), a DCL (direct Current) and an air compressor controller and the like, and have multiple functional integration schemes according to different requirements. However, the positions of the distributed controllers are inconvenient for electrical connection, the sizes of the all-in-one controllers and the interface positions are unreasonable in design, and the distributed positions of the controllers and the controlled parts still have more cables and cooling pipelines, so that the problems of low integration level, heavy weight, large occupied arrangement space, complex assembly procedures, high cost and the like of the whole scheme are caused.
However, the main problems with the current designs are: the controller and the controlled part are integrated, only the connection relation inside the part is solved, but because of the requirement of a system framework, the part arrangement position is connected by preferentially considering the pipeline medium with larger occupied space, so that the integrated controller position is possibly not favorable for electrical connection, and further the connecting wire harness is longer, the assembly process is complex and the attractiveness is poor.
Secondly, the existing patent only relates to the integration of a plurality of controllers, the design boundary and interface relation constraint consideration is less, and due to the integration of a plurality of controllers, the external electrical interfaces are more, the overall volume is larger, and the size and the interface position are unreasonable, so that more limitations exist in the application process, and the improvement of the integration level of the whole fuel cell system is not facilitated; whether a plurality of controllers integrate, still be in the dispersion with controlled piece and arrange the relation, need connect through high-low pressure pencil, its pencil connection relation is numerous and diverse, the quality is heavy, occupy and arrange the space, the assembly process is complicated, easily take place to disturb, the cable easily wears out, is unfavorable for whole system's power density promotion and cost reduction.
