Abstract: Based on fuel-cycle method, this paper tries to conduct a quantitative analysis on the energy and environmental performances of battery electric vehicle (BEV) in China. Four critical indicators, energy consumption, CO2, NOx and SO2 emission, are selected for the comparison of the performances of BEV, internal combustive engineering vehicle (ICEV) and hybrid electric vehicle (HEV) in 2010 and 2020. The findings show that in 2010, the diffusion of BEV could reduce energy consumption and CO2 emission, but BEV’s fuel-cycle NOx and SO2 emissions are higher than fuel-engined vehicles’ (both ICEV and HEV) by 50% at least. In 2020, if the targets in government planning are reached, BEV’s fuel-cycle energy consumption and CO2 emission could be reduced by around 30% and its NOx and SO2 emissions could be reduced by around 80% compared with its counterpart in 2010. However, BEV’s fuel-cycle CO2, NOx and SO2 emissions are still higher than HEV’s as a result of several reasons. In the end, policy recommendations for how to improve BEV’s energy and environmental performances are proposed, such as integrating the deployment of BEV into the progress of desulfurization and denitrification in electricity system, the management policy for automobiles should be based on vehicles’ energy efficiency, and so on.

Key words: battery electric vehicle, fuel cycle, energy conservation, pollutant reduction, carbon emission
