Problems solved by technology

[0004] At present, the calculation of the cruising range of hydrogen fuel cell vehicles in China does not take into account the parking power consumption of hydrogen fuel cell vehicles, so it is impossible to accurately count the power consumption of hydrogen fuel cell vehicles, which eventually leads to the calculation of the cruising range of hydrogen fuel cell vehicles. The mileage is not accurate

Abstract

The invention discloses a method and a device for calculating the endurance mileage of a hydrogen fuel cell vehicle. The method comprises the following steps: firstly, obtaining electric quantity data and speed data of the hydrogen fuel cell vehicle; obtaining the states of the hydrogen fuel cell vehicle according to the speed data, wherein the states comprise the parking state and the driving state; and finally, calculating and obtaining power consumption data according to the state of the hydrogen fuel cell vehicle and the electric quantity data, and then calculating and obtaining the endurance mileage of the hydrogen fuel cell vehicle according to the power consumption data. By adopting the embodiment of the invention, the accuracy of calculating the endurance mileage can be improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell vehicles, in particular to a method and device for calculating the cruising range of a hydrogen fuel cell vehicle. Background technique [0002] Because hydrogen fuel cells have the advantages of zero emission, fast fuel filling, and wide range of fuel sources, they have attracted more and more attention from the scientific and industrial circles around the world. At present, electric vehicles using hydrogen fuel cells as the main power source have been developed and put on the market around the world. [0003] Hydrogen fuel cell vehicles are different from power battery vehicles or traditional fuel vehicles. The fuel used is hydrogen, which is stored in a high-pressure gas cylinder in a gaseous state. During the driving process of a hydrogen fuel cell vehicle, the hydrogen in the high-pressure gas cylinder will be continuously consumed. , making it participate in the electrochemical r...
