Calculation modeling and analysis of carbon emission reduction of battery electric passenger vehicles in use phase

Abstract

With the proposal of China's dual carbon goals, the carbon emission reduction contribution of battery electric vehicles in use phase has gradually attracted the attention of the industry. At present, the method for calculating carbon emission reduction of battery electric vehicle in use phase is ambiguous and subjective. This study proposes an objective baseline determination method based on the curb weight parameters of vehicles, which is simpler and clearer. On the basis of baseline determination, an calculating model for carbon emission reduction of battery electric passenger vehicle in use phase is built, and the carbon emission reduction is calculated and analyzed. The analysis result shows that the carbon emission reduction of battery electric passenger vehicles in use phase in China presents a basic trend of "high in the east and low in the west, high in the south and low in the north". The vehicle types that make greater contribution to carbon emission reduction are Class A, Class A00 and Class B, and the contribution to carbon emission reduction is obviously related to vehicle age. In the future, the continuous increase in the production and sales of battery electric passenger vehicles will further enhance the contribution of battery electric passenger vehicles to carbon emission reduction.
