Design method for generalization of hydrogen fuel cell

Abstract

The invention discloses a design method for generalization of hydrogen fuel cells, which comprises: respectively acquiring the maximum available space of the mounting positions of the hydrogen fuel cells of two different vehicle models, defining the maximum effective utilization space according to the mounting requirements of the hydrogen fuel cells, and calculating the boundary dimension of the maximum public part of the two models through modeling; and designing a universal external interface on a universal battery by taking the battery as a universal appearance size and combining the whole vehicle structure arrangement characteristics of different vehicle types. The method has the beneficial effects that the research method of the hydrogen fuel cell generalization design envelope and size expansion is provided by combining the whole vehicle structure characteristics of mainstream commercial vehicles and passenger vehicles and adopting Boolean operation, so that the generalization design of the hydrogen fuel cell within a certain vehicle type range is realized, the complexity degree of matching with the whole vehicle arrangement is reduced, the product diversity is reduced, the development period is shortened, and the positive effect on reducing the cost of the whole vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell vehicles, in particular to a general design method for hydrogen fuel cells of different vehicle types. Background technique [0002] Hydrogen fuel cell vehicles are in a period of vigorous development. There are many kinds of hydrogen fuel cells on the market, but there is no unified rule for the design of hydrogen fuel cells with different powers. Even within the same manufacturer, there is no serialized design strategy. [0003] The design of the hydrogen fuel cells carried by mainstream hydrogen fuel vehicles is only based on matching with the vehicle layout of this model, and less consideration is given to the convenience of matching with other models. Therefore, there will be many differences when adapting to other models, which is bound to It will reduce the versatility of hydrogen fuel cells among different models.
