An EV Charging UX Design Exploration for Broader Distribution of Level 2 Charging System with Improved User Experience

Abstract

The growth of the Electric Vehicle (EV) market has led to the development of an efficient and user-friendly charging infrastructure. This paper evaluates the current public EV charging infrastructure growth landscape. It identifies a gap in accessibility and convenience due to their limited number and geographical concentration, mainly with Level 3 DC fast chargers. As an alternative, the paper proposes a strategy focusing on the widespread distribution of Level 2 charging systems, incorporating User Experience (UX) design principles to enhance accessibility and ease of use. The strategy suggests equipping all EVs with portable Level 2 chargers and increasing the availability of low-cost charging ports in diverse parking locations, thus integrating charging into daily routines. The innovative unibody design of the portable Level 2 charger, combined with the deployment of more AC power outlets and the introduction of digital technology for real-time charging status and control, aims to improve convenience and charging efficiency. Furthermore, the paper advocates a dual-track approach, maintaining Level 3 DC fast chargers for long journeys while promoting Level 2 solutions for everyday use. This integrated approach seeks to address current infrastructural limitations and foster a more sustainable, user-friendly, and widely accessible EV charging network, thereby accelerating the adoption of EVs and contributing to environmental sustainability.
