Abstract

The invention discloses a fuel cell control method of a hydrogen fuel cell vehicle, and belongs to the field of pure electric vehicles. The fuel cell control method of a hydrogen fuel cell vehicle comprises the following steps: 1) in a hybrid mode, acquiring a vehicle state; 2) judging whether the change frequency of a vehicle demand power is smaller than a preset value or not according to the obtained vehicle state; 3) determining a control mode of the fuel cell according to a judgment result; if the vehicle demand power change frequency is smaller than the preset value, enabling the fuel cell to enter a two-parameter control mode; otherwise, enabling the fuel cell to enter a single-parameter power cell SOC control mode. According to the control method, on the premise that vehicle power is met, it can be guaranteed that output of the fuel cell is stable as much as possible, and therefore the service life of the fuel cell is prolonged.

Description

technical field [0001] The invention belongs to the field of pure electric vehicles, in particular to a method for controlling a fuel cell of a hydrogen fuel cell vehicle. Background technique [0002] At present, the electrification of automobiles has become a mainstream development direction of the global automobile industry, and the pure electric automobile industry has initially formed an industrial chain under the influence of policies and capital. The pure electric cruising range restricts the development of pure electric vehicles. Compared with ICE hybrid vehicles, hydrogen fuel cells are the most likely solution in the future, and can also overcome the disadvantages of poor low temperature performance of pure electric vehicles. [0003] Hydrogen fuel cells convert chemical energy into electrical energy with high efficiency and no pollution. At present, some foreign manufacturers such as Ballard, Toyota, and Hyundai have relatively mature fuel cell technologies. Toy...
