Abstract

As global warming and depletion of fossil fuel are considered as urgent problems, the development of electric vehicle (EV) is getting more attention by automobile industry. However, the wide adoption of EVs is not coming yet, because of many issues such as long recharging time and high cost of batteries etc. As an alternative solution to the conventional battery charging EV, the idea of battery exchanging EV is introduced. To realize the battery exchanging business model, one should solve the issues of ownership and reliability of battery. To address such issues, the concept of battery sharing should be considered together with good traceability system. In this study, we studied RFID code structure to provide better visibility and traceability for shared EV batteries. The proposed RFID code and code generation system is based on GRAI-96 of EPCglobal and included factors such as chemical, physical, and manufacturing features. The designed code can be also used as the ID of each battery.

지구 온난화, 화석연료의 고갈 등이 중요한 문제로 대두됨에 따라 전기자동차가 관심을 얻고 있다. 그러나 배터리 충전 시간, 높은 배터리 제조비용 등은 전기자동차가 널리 보급되는데 장애요인이 되고 있다. 이런 기술적 문제점을 해결하기 위한 대안으로 배터리를 교체하여 운행하는 운영 방식이 개발되었다. 배터리 교체형 시스템에서는 배터리의 공급망이 복잡하기 때문에 배터리의 신뢰성 확보 및 관리의 효율화를 위해서는 배터리 이력추적 시스템의 구축도 함께 진행되어야 한다. 본 연구에서는 전기자동차 배터리 이력추적 시스템에서 배터리 식별을 위해 사용될 RFID 코드를 설계하였다. 설계된 코드는 EPCglobal의 GRAI-96 표준을 기반으로 하였으며 배터리의 외형적 특성, 화학적 특성, 제조사, 제조일 등을 반영하였다. 설계된 코드는 RFID 코드뿐만 아니라 각 배터리의 개체식별번호로도 적용이 가능하다.
