| dc.description.abstract | Within the automotive industry nowadays, a significant transformation is currently happening, transitioning from combustion engine vehicles to more sustainable alternatives, including Plug-in Hybrid Electric Vehicles (PHEVs) and Battery Electric Vehicles (BEVs). With more and more consumers coming to the fully-electric vehicle market, the new regulations concerning the battery State of Health (SoH) of Electric Vehicles (EVs) have been regulated and used as a standardisation for automotive manufacturers to implement battery SoH feature by 2026. This new legislation is not only new to the EV drivers but also novel to the vehicle manufacturers in the automotive industry. However, compliance with the regulations does not take into account the user experience. Moreover, the scarcity of research in this area makes it potentially challenging to understand the user needs and goals. This thesis investigates how the information of battery SoH should be displayed from a user-centred perspective, with the aim to improve user understanding of battery health and increase their engagement with the BEV battery health maintenance. The study takes a user-centred design approach to better understand user needs and develop the most appropriate approach to display battery SoH to drivers. During the process, several research and design methodologies including literature review, questionnaire and focus groups, have been conducted to understand the users, frame the problem spaces, and identify the user requirements for further development. With the defined user requirement list, different resolution levels of prototypes were developed and evaluated in three iterations, with a total of 15 participants involved across these iterations, to ensure that the design concept met their expectations and requirements and that the prototypes were refined efficiently based on their feedback. The findings revealed that simply displaying SoH as a percentage is insufficient to inform users about the current state of their battery health and additional contextual information and actionable guidance are needed. This thesis presents a series of design recommendations as deliverables, derived from research, analysis, and evaluation of the design concept. These recommendations were established with the aim of enhancing the user experience and understanding of battery SoH information displayed in BEVs, also serving as guidance for the implementation of the SoH functionality in the BEVs in the upcoming future. | |
