Problems solved by technology
There is no judgment standard for replacing the filter element based on experience, the reliability is poor, and regular inspection is required, which requires a large labor cost
At the same time, due to the different pollution levels of the air filter element in different locations and vehicle operating conditions, regular replacement of the filter element may be wasteful or cannot be replaced in time

The invention provides a method for calculating the pollution degree of an air filter part for a fuel cell vehicle. The method for calculating the pollution degree of the air filter part for the fuel cell vehicle comprises the steps that operation time periods of an engine of the fuel cell vehicle under different operation powers are obtained; collecting the concentration of air pollutants at the location of the fuel cell vehicle in each time period; obtaining the air flow of each operation time period according to the operation power of each operation time period; and calculating the pollution degree of the air filter part of the fuel cell according to the operation time period of the engine of the fuel cell vehicle, the concentration of the air pollutants and the air flow in each operation time period. The method has the advantages that the pollution degree condition of the fuel cell is calculated according to the running time and place of the vehicle, a basis is provided for judging whether the filter part needs to be replaced or not, replacement of the filter part does not depend on manual judgment or regular replacement any more, replacement of the filter part is more timely, and meanwhile waste possibly caused by regular replacement can be avoided.
Description
technical field [0001] The invention relates to a calculation method for the pollution degree of an air filter element for a fuel cell vehicle, in particular to a calculation method for the pollution degree of an air filter element for a fuel cell vehicle. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy generated by the reaction of hydrogen and oxygen into electrical energy through an electrochemical reaction. It has the advantages of high power generation efficiency and low environmental pollution, so it is widely used in the automotive field. Hydrogen fuel cells generate electricity and output power through the catalytic combustion reaction of hydrogen and oxygen in the air. The air filter element is an important part of the air subsystem of the fuel cell. Its function is to filter impurities such as dust in the air. The air filter element needs to be replaced after a period of use to ensure that th...
