摘要

Recently, as Electric Vehicles (EVs) have become more widespread and more people are enjoying outdoor activities after the COVID-19 pandemic, car camping has become popular. Currently, diesel generators or battery banks are primarily used for cooking and lighting during camping; however, they have significant drawbacks, including being highly susceptible to environmental pollution and fire hazards. As a result, there is growing interest in V2L (Vehicle-to-Load) devices, which can convert the EV’s traction battery power to household electricity for use. Recognizing this trend, the government is encouraging the adoption of EVs with V2L functionality by providing subsidies. However, despite being high-risk power devices that use voltages above 30Vac, V2L devices are not subject to specific safety tests in Korea, and international standards, such as those from the IEC, have not yet been established. Therefore, there is a high risk of accidents that could endanger users. In a similar case, fires broke out during electric vehicle charging, raising concerns among many people. In this study, to prevent such risks in advance, safety testing items tailored to the characteristics of V2L devices are proposed. In particular, safety assessments using commercially available products were conducted to perform the proposed tests and verify whether these testing items could be used to evaluate safety.
