Abstract

As the range of battery electric vehicles (BEVs) increases, the carbon footprint generated during the use phase is rarely investigated and compared. The carbon footprint of BEVs with different ranges during the use phase is quantified and analyzed using the life cycle assessment (LCA) method to explore the optimal range from a low-carbon perspective. The study comprehensively considers the battery deadweight, charging and discharging cycle efficiency energy loss, and abatement portion of the kinetic energy recovery system (KERS) in the carbon footprint accounting. Results show that: (1) At the range of 300 km and above, the carbon footprint from the self-weight of batteries is more significant than due to charge/discharge cycles. (2) A KERS carbon abatement analysis based on the established 15 driving conditions is performed, in which the initial speed is the most influential parameter. (3) Carbon footprint varies considerably from vehicle type and positively correlates with the charge/discharge rate. (4) A range of 500–600 km is the best choice for BEVs in northern China, considering the range and low carbon requirement at low temperatures. Reliable data references for automobile manufacturers and policy decision-makers are provided to promote BEVs' sustainable development and policy formulation science.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
