ABSTRACT: Electric cars are a promising alternative to combustion engine cars to lower emissions and fossil fuel dependencies. However, many are skeptical to this unfamiliar technology and the limited driving range of these vehicles. Therefore, people disregard this option without properly knowing if it is a good practical alternative. This is unfortunate, as electric cars according to studies should cover most people’s needs. In this paper, we will share our results from a real-world study where 8 participants used an app designed to simulate the battery of electric cars using a regular combustion engine car. In this way it is intended to let people assess their real needs in their real context. Our results show that this might be an effective tool to overcome psychological barriers associated with electric cars, as they do not only assess electric cars and infrastructure, but also their own needs and habits. We also suggest a shift from a kWh and bar perspective to apercentage-perspective as our users easily could work with percentage to figure out the driving range and plan ahead. Our study also elevated a number of uncertainties causing unnecessary worries among our participants.
