Abstract

The invention discloses a method and device for evaluating a power distribution strategy of a vehicle based on a cyclic working condition. The method conducts a cyclic working condition pre-test and a cyclic working condition test on the vehicle to be evaluated, and obtains the cycle condition of the vehicle to be evaluated in a single cycle during the pre-test process. The power consumption under working conditions, the current power of the power battery pack and the hydrogen remaining amount of the vehicle to be evaluated are recorded during the test, that is, the third power and the first and second hydrogen remaining. When the power is used, the vehicle to be evaluated is obtained according to the power consumption, the third power, the preset power, and the first and second remaining amounts of hydrogen, or when the third power is equal to the preset power, according to the first and second remaining hydrogen The hydrogen consumption under a single cycle condition is finally compared with the hydrogen consumption under different power distribution strategies. Pros and cons of power allocation strategies.

Description

technical field [0001] The invention relates to the field of fuel cell hybrid vehicles, in particular to a method and device for evaluating a vehicle power distribution strategy based on a cycle condition. Background technique [0002] Due to the late start and relatively slow development of hydrogen fuel technology in my country, with the increasingly prominent energy shortage and environmental problems, my country has begun to attach importance to the research and development of hydrogen fuel cell vehicles. At present, major hydrogen fuel vehicle companies have their own power distribution control strategies. Under different power distribution strategies, the whole vehicle is tested under the same working conditions, and the power consumption and hydrogen consumption of the power battery pack are different. However, for cycle conditions, a complete evaluation method has not yet been proposed to evaluate the pros and cons of different power distribution strategies. SUMMAR...
