德国政府的目标是到2020年在德国发放100万辆电动汽车（EV）的许可证。然而，今天的电动汽车（EV）数量仍然略高于25，000辆。有几个原因决定反对电动汽车，但特别是低电池范围以及太长的感知充电持续时间抑制电动汽车的使用。为了消除这两个原因对电动汽车购买决策的负面影响，建立了一种新的充电技术。快速充电技术使用户能够在20-30分钟内将电池充电至其充电状态（SOC）的80%。为了从（潜在）用户的角度研究该技术的影响，通过考虑不同的旅行目的和与常规充电选项的比较，向电池电动汽车的用户和非用户询问了公共快速充电基础设施的感知附加价值。结果显示，增加感知价值，特别是与休闲目的的旅行，考虑到他们的份额在德国的所有旅行目的，根据2008年的MiD。为了增加德国获得许可的电动汽车数量，该研究的结果还建议进一步传播有关快速充电的信息，这可能会影响该技术的感知有用性，从而影响电动汽车的感知有用性。
The aim of the German Government is the licensing of one million electric vehicles (EV) in Germany until 2020. However, the number of battery electric vehicles (EVs) today still is just above 25,000. There are several reasons for deciding against an EV, but especially low battery ranges as well as too long perceived charging duration inhibit the usage of an EV. To eliminate the negative influence of these two reasons on the decision to purchase an EV, a novel charging technology is established. The rapid-charging technology enables the user to recharge the battery to 80% of its state of charge (SOC) within 20–30 min. For the examination of the technology’s impact from (potential) user’s perspective, users and nonusers of battery electric vehicles were questioned about the perceived additional value of public rapid-charging infrastructure by taking into account different trip purposes and running comparisons to regular charging options. The results show an increased perceived value especially for trips with leisure purpose, considering their share of all trip purposes in Germany, according to the MiD 2008. In order to increase the number of licensed EVs in Germany, the study’s results also suggest further dissemination of information on rapid charging which might influence the perceived usefulness of the technology and consequentially the perceived usefulness of an EV.
