Abstract: Electric vehicles (EVs) are becoming increasingly popular in the global market while their electric range is increasing due to advancements in battery technology. This study provides a comprehensive analysis of the usage patterns and electric range requirements through real-world usage data in Shenzhen, a pioneer city of adopting EVs. We found that the driving habit has not changed significantly with the application of EVs, in the city with well-developed charging infrastructure and suitable temperature conditions. An evaluation system was developed to guide consumers in selecting the appropriate electric vehicle range, with results showing that longer purchased ranges often lead to greater underutilization. Among owners of vehicles with a range exceeding 450 km, approximately 74 % suggested reducing their purchased range by more than 200 km. Optimizing an EV's range by reducing it 20%–40 % can yield significant economic and climate benefits, including a life-cycle CO2 emission reduction of 100 kg/yr and savings of $1400-$2800 in total ownership costs over its lifecycle.
