Abstract

To respond to the threat of global warming, countries around the world are promoting the spread of renewable energy and reduction of carbon emissions. In accordance with the United Nation's Sustainable Development Goal to combat climate change and its impacts, global automakers are pushing for a full transition to electric vehicles within the next 10 years. Electric vehicles can be a useful means for reducing carbon emissions, but in order to reduce carbon generated in the stage of producing electricity for charging, a power generation system using eco-friendly renewable energy is required. In this study, we propose a smart electric mobility operating system integrated with off-grid solar power plants established in Tanzania, Africa. By applying smart monitoring and communication functions based on Arduino-based computing devices, information such as remaining battery capacity, battery status, location, speed, altitude, and road conditions of an electric vehicle or electric motorcycle is monitored. In addition, we present a scenario that communicates with the surrounding independent solar power plant infrastructure to predict the drivable distance and optimize the charging schedule and route to the destination. The feasibility of the proposed system was verified through test runs of electric motorcycles. In considering local environmental characteristics in Tanzania for the operation of the electric mobility system, factors such as eco-friendliness, economic feasibility, ease of operation, and compatibility should be weighed. The smart electric mobility operating system proposed in this study can be an important basis for implementing the SDGs' climate change response.

전 세계적인 지구온난화의 위협에 대응하고자 세계 각국은 신재생 에너지의 확산, 탄소 배출 감소 등을 추진하고 있다. 또한, UN의 SDGs에도 포함된 기후변화에 맞서기 위한 노력으로 글로벌 자동차 제조사들은 향후 10년내에 전기 자동차로의 전면 전환을 추진하고 있다. 전기자동차는 탄소 배출 감소를 위한 유용한 수단이 될 수 있으나, 충전용 전기를 생산하는 단계에서 발생하는 탄소의 저감을 위해서는 친환경 신재생 에너지를 이용한 발전시스템이 요구된다. 본 연구에서는 아프리카 탄자니아에 설립된 태양광 발전소와 통합된 스마트 전기 모빌리티 운영 시스템에 대한 비전을 제안한다. 아두이노 컴퓨팅 장치를 기반으로 하는 스마트 모니터링 및 통신 기능을 적용하여 전기자동차 또는 전기 오토바이의 배터리 잔존용량, 배터리 상태, 위치, 속도, 고도, 도로 상태 등의 정보를 모니터링한다. 또한, 주변의 독립형 태양광 발전소 인프라와 통신하여 주행가능거리를 예측하고 충전 스케쥴 및 목적지까지의 경로 최적화를 수행하는 시나리오를 제시한다. 제안된 시스템의 구현 가능성은 전기 오토바이의 시험운행을 통해 검증되었다. 탄자니아에서 운영될 전기 모빌리티 시스템은 현지의 환경과 특성을 고려하여 친환경성, 경제성, 운용 용이성, 호환성 등의 요소가 고려되어야 한다. 본 연구에서 제안하는 스마트 전기 모빌리티 운영 시스템은 SDGs의 이행을 위한 중요한 기반이 될 수 있을 것이다.
