User-Centered Development and Evaluation of a Physical Ultrafast Charging Interface

As part of the publicly funded CoolEV research project, the Faculty of Mobility and Technology (MT) at Esslingen University of Applied Sciences is developing, among other things, a new type of charging interface that will enable fast charging and simultaneous cooling of electric vehicles. The aim of such a charging interface is to enable vehicle users to achieve charging times that are comparable to the time of a conventional refueling process, especially on long-distance journeys. This paper aims to answer the question of whether such an interface is usable for all vehicle customers from an ergonomic point of view and also increases the user's utility value.
