Energy Flow

Abstract

The lack of sound and vibration while starting the drive system of an electric vehicle (EV) is one of the major differences compared to a conventional car with a combustion engine. Most EVs provide a visual feedback about the energy level to the driver. With Energy Flow (see Figure 1), we test if there will be a benefit in terms of attractiveness through adding audible or haptic feedback. First results show a positive effect by addressing several senses -but disprove the hypothesis "the more the merrier".

Investigating EV Driving as Meaningful Practice

“…Our study shows that expectations continue to play an important role when people embed the EVs into driving practices, despite the many regarded concerns and uncertainties associated with driving EVs [26,34,36]. Our findings illustrate how participants adapted expectations they associated with driving in their EVs.…”

“…Following HCI discourses on sustainability, we have seen an interest in electric vehicles (EV's) in later years. A significant number of HCI studies on EV's have focused on the challenges and opportunities in adopting and driving these, as they form a new kind of driving experience compared to a fossil-fuelled car [26,34,36]. To this end, several studies investigate range-related issues such as range anxiety where drivers worry about the depletion of the battery before they reach their destination [26].…”

“…[26,36,37,57]). As examples, Jung et al [26] explore the impact of displayed uncertainty in the car's instrumental estimates of range, while Landau [34] focuses on creating an interface that makes up for the lack of feedback in EVs, for example, the lack of sound or vibration, or knowing when the EV is ready to drive.…”

“…Towards this end, HCI research has studied how to design interfaces to reduce drivers worrying about battery depletion (e.g. [26,34,36,37]). However, few HCI studies have investigated actual use in peoples everyday lives and how people find meaning in electric driving.…”

Power to the Electric Car People: The Infrastructuring of Charging

“…In HCI research, several studies are oriented towards designing interfaces for the electric car [18,22,[28][29][30][31]. Much of this research is design-oriented investigating how to address the perceived shortcomings of electric cars compared to fossil-fueled cars [4].…”
