Abstract

The environmental regulations are being strengthened all over the world, and the introduction of electric vehicles are actively being considered to cope with them effectively. It is essential to establish a charging infrastructure, which is an essential element of electric vehicle distribution. In this paper, power line communication technology essential for smart charging infrastructure is studied. A control board capable of achieving a physical layer speed of 10Mbps and a TCP/IP layer of 4.5Mbps, which conforms to the ISO/IEC 15118 international standard, and a control board mounted on the board and compliant with international standards. We have developed a software solution to perform functions for linking. In addition, in order to be applied to the combo-type DC fast charger, the hardware was designed to meet the industrial environment standard and the V2G communication module was developed by integrating it with the software solution.

전 세계적으로 환경규제가 지속적으로 강화되고 있으며 이에 효과적으로 대응하기 위해 전기자동차의 도입이 적극적으로 고려되고 있으며, EV 보급의 필수요소인 충전인프라 구축이 필수적이다. 본 논문에서는 스마트한 충전인프라 구축에 필수적인 전력선 통신 기술에 대하여 연구하였다. ISO/IEC 15118 국제표준에 부합한 HPGP규격의 물리계층 속도 10Mbps 및 TCP/IP계층 4.5Mbps 성능을 달성할 수 있는 제어보드와 해당 보드에 탑재되어 국제표준에 부합하는 충전단계 및 향후 지능형전력망과의 연계를 위한 기능을 수행할 소프트웨어 솔루션을 개발하였다. 또한 Combo 방식의 DC 급속충전기에 적용하기 위해 산업 환경 기준에 적합하도록 하드웨어를 설계하였으며 소프트웨어 솔루션과 함께 통합하여 V2G 통신 모듈을 개발하였다.
