Preliminary Exploration on the Calculation of Carbon Footprint for Automotive Power Batteries

Abstract

In recent years, global warming has intensified, prompting countries worldwide to promote electric vehicles (EVs) as a sustainable alternative to traditional fuel-powered cars. This shift aims to accelerate transportation electrification, reduce greenhouse gas emissions, and achieve carbon neutrality goals. However, while the adoption of new energy vehicles is crucial for environmental protection, accurately assessing the carbon emissions generated throughout the entire lifecycle of automotive batteries remains a significant challenge. This paper explores the carbon footprint calculation of EV power batteries, analyzing current evaluation methodologies, key influencing factors, and potential improvements. Existing research highlights discrepancies in emissions measurement due to variations in battery production, usage, and recycling processes. Factors such as raw material extraction, manufacturing energy sources, and end-of-life disposal significantly impact overall emissions. Additionally, this study discusses future development directions, including advancements in battery technology, standardization of carbon accounting frameworks, and policy recommendations to enhance sustainability. By addressing these challenges, the transition to electric mobility can achieve its full environmental potential.
