Unit Process Inventory Data for Residential Electric Vehicle Charger Life Cycle Assessment

Report, 2023

This technical report has been written as joint deliverable from two projects, one named “Environmental Assessment of Electromobility Charging Systems”, funded by the Swedish Electromobility Centre, and one named “Techno-environmental assessment of stationary EV charging solutions”, funded by the Area of Advance Energy at Chalmers University of Technology.
Prevalent literature often excludes the infrastructure required for actualizing a transition to electric vehicles (EVs), namely electric vehicle supply equipment (EVSE) in transportation system assessments. This knowledge gap also extends into the domain of life cycle assessment of EVSEs. The existing body of work is limited in number and deviates notably from the charging equipment’s practicalities and representativeness. A reason is a lack of unit process inventory data that is detailed, compatible, consistent, and compliant with market trends, normative specifications and guidelines embodied in international standards and sometimes even mandated by regulations governing EVSE installation and utility interfacing. This report attempts to fill this gap and advance the body of knowledge on residential EV charging by compiling unit process data and developing a model coherent model file.
