Development of a charging information tool for heavy-duty trucks : How to make the person responsible for charging feel in control of the process

Abstract: The aim of this thesis project is to contribute to an understanding of which charging monitoring solutions for mobile phones are valuable and possible for Scania to implement. These solutions are intended to make the person responsible for charging feel in control of the process. This project focuses on the implementation of a graphical user interface (GUI), with the possible integration of a server that is developed by another thesis worker at Scania. The scope is set to looking at the possibilities and limitations for one charging station, one vehicle and one driver.  Designing good user interfaces is more than mapping user needs to solutions. To design good interfaces, the technological possibilities and limitations must also be considered. This has partly been done by integrating and testing some relevant features with Scania’s battery electric trucks.  In terms of creating value for the user, the driver, a contextual design approach, developed by Hugh Beyer and Karen Holtzblatt, has been chosen. In this way, different solutions can be designed in a user-centered way. One of the results of this project is a minimum viable product (MVP) that Scania or other thesis workers can continue to develop. This MVP has mainly one feature that has been implemented and tested briefly.  The conclusion is that charging monitoring solutions that make drivers feel in control of the charging process have interfaces and interactions that are perceived as relevant by the driver. The relevant features are those that drivers would expect to have access to.
