Measuring Development of Charging Infrastructure Development in Selected Countries: Metrics and Comparison

摘要

Charging infrastructure plays an essential role in the development of electric vehicles. In this study, we evaluate the coverage level of charging infrastructure in five countries the U.S., China, Japan, the Netherlands and Germany. Electric vehicles stock, the number of charging outlets, and road lengths are the key inputs. The results indicate that all selected countries develop electric vehicles and charging infrastructure in a positive trend. However, these countries still need to improve the coverage of charging facilities. The development levels of electric vehicles and charging infrastructure are affected by many factors, like policy, territory areas and etc.
