Understanding Emotional States and Charging Behaviors for Decision Making and Battery Preservation in Electric Vehicles

Abstract

Understanding battery electric vehicle (BEV) charging behavior is essential for improving driver experience, battery life, and reducing range anxiety. This study examined charging frequency, battery level, charging rate, and emotional states of BEV drivers over a 2-week period. Findings suggested that BEV drivers did not always charge their vehicles to full, likely due to infrastructure limitations or battery life concerns. Range anxiety and habitual behavior may influence charging decisions, as reflected in the preference to charge at moderate battery levels. While some drivers developed routines to mitigate stress, others remained concerned about the long-term effects of charging habits on battery life and resale value. Additionally, the impact of fast charging on battery health could shape user behavior, with some drivers avoiding fast charging unless necessary. This study demonstrates the feasibility of real-time behavioral data collection and identifies variables for future studies, informing human-centered strategies to balance convenience with battery longevity.
