전기버스 충전 인프라의 요소 표준화 연구 : 경기도 운영 사례 조사를 중심으로

Abstract

Gyeonggi-do recognizes the need for eco-friendly transportation and the efficient management of city bus fuel costs, leading to the expansion of electric bus adoption. In order for electric buses to operate smoothly, charging infrastructure, including electric bus charging stations and charging management systems, is essential. As the deployment of electric buses increases, charging infrastructure is being developed and distributed by various manufacturers. However, bus transportation companies, as end users, have pointed out issues with the charging infrastructure, such as technical limitations and challenges in meeting user demands due to the rapid increase in demand. This study categorizes the technologies related to electric bus charging infrastructure into protocols, smart charging, charging management systems, and the certification of charging stations and charging management systems. Furthermore, through IPA (Importance-Performance Analysis) and influence index analysis, the study derives priority categories for the standardization of Gyeonggi-do's electric bus charging infrastructure. Electric bus charging infrastructure can be standardized by categorizing it into communication protocols, integrated control, smart charging management, and general control areas. This approach is expected to enhance compatibility between electric bus charging stations and charging management systems, thereby improving user convenience and safety. Furthermore, policy support will be necessary, including strengthening the roles of central and local governments in managing charging infrastructure, and establishing a collaborative model for setting standards for Gyeonggi-do’s electric bus charging infrastructure.
