In rapidly urbanizing cities of sustainable developing countries like India, electric vehicles (EVs) play a crucial role in shaping future urban mobility. This study examines the impact of EV adoption and battery management systems under mixed traffic conditions in Chandigarh. Using a mixed-methods approach, the research integrates both quantitative and qualitative analyses to systematically evaluate the implications of EV adoption. The findings highlight key challenges, including infrastructure readiness, environmental impact, and economic concerns. Despite the UT administration’s commitment to establishing 100 public EV charging stations, the initial 23 stations installed across 37 locations after the policy’s introduction in September 2022 remain non-operational. To address this, the city has approved 48 additional charging stations under the FAME India program, aimed at accelerating the adoption and production of hybrid and electric vehicles. Looking ahead, this research will focus on the broader economic and environmental benefits of EVs, particularly their role in reducing carbon emissions and air pollution. These advancements align with the United Nations’ Sustainable Development Goals (SDG-2030), reinforcing the significance of EV integration in achieving global sustainability targets.
