Power System Cycle Impact Data Based on Electric Internal Combustion Engines

Nowadays, some companies are turning their attention to Life Cycle Assessment (LCA) of automobiles in order to control energy consumption, reduce production costs, and improve production efficiency. This article intended to take a Chinese brand of pure electric vehicles (EVs) and internal combustion engine vehicles (ICEVs) as the research objects. By comparing the life cycles of the two driving modes, the environmental effect characteristics at different stages of the full life cycle were obtained, and the key factors that have a significant impact on the environment were identified. Given that the main focus of this study is to compare the environmental effects of fuel vehicles and electric vehicles, in addition to the composition of electricity consumption in the Chinese power grid, all relevant data on upstream raw materials and energy production processes were sourced from GaBi. This article intended to supplement the Chinese LCA database by improving it based on it. In the calculation of comprehensive environmental effects, it was assumed that all environmental influencing factors were equal, and the weights of each factor were equal. In the stage of obtaining raw materials, the normalized result of eutrophication was 0.57. In the production and manufacturing stage, the normalization result of acidification was 0.5. This article helped guide designers to optimize design and reduce the impact of vehicles on the environment.
