Performance Comparison of BEV and PHEV under Beijing Policy Incentives (2020-2025)

Abstract

The study aims to discuss the performance comparison between battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) in the context of policy incentives in Beijing from 2020 to 2025. Under the impetus of sustainable development policies, Beijing has guided the popularization of new energy vehicles through a series of policies to reduce operational energy consumption and carbon emissions. The study will compare and analyze their overall performance from background, technical principles, energy consumption, and full life cycle carbon emissions. BEVs have significant advantages in energy consumption and full life cycle carbon emissions, but they face challenges such as low energy density batteries and uneven distribution of charging facilities; PHEVs rely on fuel resources and cause higher carbon emissions. The study expects that both will coexist in the short term, but with the strengthening of low-carbon requirements and the improvement of infrastructure, BEVs are expected to gradually take the lead.
