Research on Key Factors of the Life Cycle Carbon Emission for Battery Electric Vehicles

Abstract

With the ever increasing energy crisis and environmental issues globally in recent years, China is enhancing the processes of automobile electrification. Compared with traditional fuel vehicles, Battery Electric Vehicle (BEV) has lower carbon emission level during the whole life cycle, which is one of important technical routes for the low-carbon development of the automotive industry. Based on the main influencing factors of carbon emission for BEVs, this paper focuses on the correlation between the five key factors and carbon emission, including vehicle mileage, power grid cleaning, energy consumption level, battery energy density and utilization rate of renewable materials, and proposes development suggestions for carbon reduction ways for BEVs.
