Embodiment approach

[0142] A plug-in heavy-duty hybrid electric vehicle carbon emission conversion method provides a means for the assessment and supervision of heavy-duty hybrid electric vehicles carbon dioxide / greenhouse gas emissions, and helps to achieve the development goal of carbon peaking and carbon neutrality in China. The present invention will achieve the desired effect by implementing the following steps.

[0143] Step 1: During the chassis dynamometer test of the plug-in heavy-duty hybrid electric vehicle, three stages: the pure electric driving range stage, the energy adjustment stage of the energy storage device and the power balance operation stage need to be tested in sequence. During the test, the requirements of the tested vehicle and test equipment were implemented in accordance with the standard GB / T 19754-2015.

[0144] Step 2: The calculation of the UF coefficient should be divided according to the vehicle type, and calculated according to the parameters corresponding to th...

Abstract

The invention provides a carbon emission conversion method for a plug-in heavy hybrid electric vehicle. The carbon emission conversion method comprises the following steps: calculating a charging frequency UF coefficient; calculating power consumption in a pure electric driving mileage stage; calculating oil consumption and power consumption of the energy storage device in the energy adjusting stage; calculating oil consumption in an electric quantity balance stage; calculating comprehensive fuel consumption and power consumption of the vehicle; calculating the comprehensive converted fuel consumption of the vehicle according to the comprehensive fuel consumption and the power consumption of the vehicle; and calculating the carbon emission of the vehicle according to the comprehensive converted fuel consumption of the vehicle. According to the method for converting the carbon emission of the plug-in heavy hybrid electric vehicle, the carbon emission of the heavy hybrid electric vehicle is calculated from a fossil fuel end, the actual carbon emission level of the heavy hybrid electric vehicle is researched, and an effective hybrid electric vehicle energy consumption evaluation system is established; the carbon dioxide / greenhouse gas emission evaluation method suitable for the plug-in type heavy hybrid electric vehicle is provided for environmental protection departments, detection institutions and enterprise manufacturers.

Description

technical field [0001] The invention belongs to the technical field of carbon emission testing and evaluation of heavy-duty hybrid electric vehicles, and in particular relates to a carbon emission conversion method for plug-in heavy-duty hybrid electric vehicles. Background technique [0002] In 2020, my country clearly stated at the United Nations General Assembly that carbon dioxide emissions should peak by 2030 and strive to achieve carbon neutrality by 2060. The goal of carbon peaking and carbon neutrality has brought new challenges to the automobile industry and provided opportunities for the further development of the new energy automobile industry. In order to comply with the direction of green and low-carbon development, the automobile industry should accelerate the in-depth transformation of low-carbon, near-zero and zero-carbon, continuously reduce carbon emissions and pollutant emissions from the entire life cycle of vehicles, and promote the national carbon peak ...
