This study investigates the user onboarding experience in electric vehicle (EV) charging services, focus on the challenges encountered by new users, especially in comprehending and navigating the charging process. Employing a combination of questionnaires and principal component analysis, the research explores the cognitive and emotional aspects of initial interactions with EV charging technology. The experimental setup featured a simulated EV charging station interface, where participants completed tasks mirroring real-life scenarios. Data analysis unveiled pivotal factors impacting user experience, including the clarity of instructions, cognitive load, and the overall intuitiveness of the charging process. The findings indicate that while instructions are generally clear, addressing user confusion and the overwhelming nature of information presented is essential. This study underscores the importance of simplifying user interfaces and providing intuitive guidance to enhance onboarding experiences. By pinpointing areas for improvement, this research contributes to enhancing the adoption and usability of EV charging services through human- centered design. The objective is to reduce apprehension and cognitive load for new users, making the transition to EV technology more accessible and less daunting, thereby promoting broader electric vehicle adoption.
