Stationary wireless charging could be a convenient alternative to wired charging of electric vehicles. The prerequisite for efficient wireless charging is that the charging components located under the car are precisely aligned. Drivers cannot observe the state of alignment from their perspective, which makes it challenging to identify whether the vehicle's position is accurate enough. In this paper, we present user interfaces that can support the driver in achieving the technically required precision. We provide three visualizations with different abstraction levels displayed on two screen types, which we evaluate experimentally in a user study. As part of the user study, we create a positioning scenario as it might occur with wireless charging. Participants must try to achieve the required precision by being guided by the user interfaces. The results of the user study indicate that, regardless of the visualization and screen type, drivers can position the vehicle within the defined tolerance range of 10 centimeters. However, the user experience differs significantly. In terms of usability and workload, drivers prefer a visualization that presents the positioning scenario from a bird's eye view. Moreover, the time to complete the task using the bird's eye view visualization took less than 44 seconds on average, which is probably shorter than parking and plugging in a charging cable. In contrast, an arrow-based visualization took in average up to 1.5 times longer than bird's eye view visualization to complete the task and was the most criticized by the participants.
