User interaction with remote access to range-related information in BEVs

Limited range can be a challenge for battery electric vehicle (BEV) users. Remote access to range-related information (e.g., via smartphone apps) could support users. The present study examines the experience and usage of range-related remote access functions in a BEV field study setting. Twenty-nine customers leased a BEV for three months and had access to a remote-access app. On average, users perceived the range-related remote access functions as moderately supportive and usage frequency was typically between occasionally and often. Higher usage frequency was associated with more irregular/unpredictable daily mobility patterns, a higher share of away-from-home recharging, and typically less available charging time, yet affinity to technology was not. The study shows the usefulness of range-related remote access functions and identifies the user groups that might particularly benefit from these functions and therefore, should be targeted in research and development aimed at advancing remote-access functions.
