Abstract:Several electric vehicle (EV) cost studies have been prepared in recent years. These studies employ a broad range of assumptions and methodologies, and the disparate results that they report are a testament to the uncertainties surrounding the potential manufacturing costs of EVs. This report section summarizes the results of several cost studies, and briefly critiques their approaches and assumptions. A concluding section summarizes key sources of uncertainty in EV cost estimation, and reasons for the variations observed in the studies reviewed.
