A Clustering Analysis of Electric Vehicle Users’ Usage Patterns Considering Range Anxiety
Abstract
Amid global efforts to address the climate crisis and achieve carbon neutrality, the adoption of electric vehicles (EVs) is accelerating domestically and internationally. Despite this, a ”Chasm” in the technology adoption cycle has emerged as diffusion reaches a certain level, with “Range Anxiety” identified as a key cause. Range anxiety refers to a psychological concern arising from the limited driving range of EVs and the insufficient density and accessibility of charging infrastructure, which is particularly pronounced during long-distance trips or in unfamiliar areas. This study clusters range-anxiety types based on the EV users’ socio-demographic attributes and their driving and charging behaviors, and identifies inter-cluster differences in anxiety levels and charging characteristics to inform user-tailored policy design. The analysis distinguishes four user groups: a stable commuter/student group with generally low anxiety; a short-trip, early-charging, and coldweather- sensitive group; a 50–100 km mid-to-long-distance, planned-charging, and unfamiliar-areasensitive group; and a school-commute/short-distance, dual-sensitivity to cold weather, and unfamiliar areas group. The driving purpose, route regularity, charging habits, and situational factors interacted to shape range anxiety. Therefore, beyond simple capacity expansion, there is a need for demand-oriented, segment-specific charging siting and routing/charger-search algorithms linked to user-specific anxiety thresholds.
