Estimation and calculation method of greenhouse gas emission in whole life cycle of electric vehicle

Abstract

The invention provides an estimation and calculation method of greenhouse gas emission in a whole life cycle of an electric vehicle. The method mainly comprises the following steps: respectively calculating greenhouse gas emission of the electric vehicle in three stages of production, operation and scrapping, and then summarizing, thus a measured value of greenhouse gas emission in the whole life cycle of the electric vehicle can be obtained; the production stage comprises the greenhouse gas emission of four processes of vehicle body material production, vehicle-mounted battery production, automobile assembly and automobile transportation; the operation stage comprises the greenhouse gas emission of two processes of power utilization and daily maintenance; and the scrapping stage comprises the greenhouse gas emission of two processes of electric vehicle scrapping and recycling. The estimation and calculation method of the greenhouse gas emission in the whole life cycle of the electric vehicle provided by the invention can perform quantitative evaluation on a greenhouse gas emission level in the whole life cycle the of electric vehicle systematically and accurately.

Description

technical field [0001] The invention relates to the field of energy conversion and utilization and environment-climate impact assessment methods, and specifically relates to a systematic and accurate assessment method for greenhouse gas emissions of electric vehicles based on full life cycle theoretical research. Background technique [0002] With the looming oil energy crisis and the requirement of low-carbon economy, electric vehicles have become an important direction for the development of the automobile industry because of their low pollution and high efficiency.
