| Abstract |
Electric vehicle (EV) charging infrastructure is crucial for sustainable transportation electrification and achieving carbon neutrality. As the expansion of charging infrastructure accelerates to meet growing EV user demand, a comprehensive evaluation of utilization is required from various perspectives. This study presents an approach to evaluate utilization indicators that reflect the operational status of EV charging infrastructure and establish a classification framework. As a first step, the scope of EV charging infrastructure is defined, and both domestic and international market trends, along with national support policies, are analyzed. The study highlights that the significance of utilization evaluation varies depending on stakeholders’ interests. A classification system is developed based on charging variables, time intervals, and application cases. Utilization indicators are categorized by quantity, charging demand, and charging time, while evaluations are conducted over short, medium, and long-term intervals. Additionally, application cases are classified into pattern analysis, utilization maximization, impact factor exploration, and operational optimization of charging infrastructure. |
