As the electrification of the transportation sector is being promoted to achieve carbon neutrality, the promotion of battery electric vehicles (BEVs) has become an urgent issue. One of the concerns about BEVs from the user's point of view is the range anxiety that the vehicle may not be able to reach its destination due to power shortage. However, few studies have clarified the timing of the anxiety felt by users. In this study, a questionnaire survey was conducted on domestic users who switched from an engine vehicle to a BEV. As a result, it was found that the timing at which BEV users felt range anxiety and wanted to recharge their vehicles tended to be influenced by recharging habits based on individual personality factors, rather than environmental factors such as BEV driving experience and the density of rechargers. In addition, the SoC ratio of the timing of wanting to recharge was found to be correlated with the timing of recharging the BEV and the timing of recharging the cell phone.
