Abstract:

This report provides a global assessment of charging infrastructure deployment practices, challenges, and emerging best practices in major electric vehicle markets, with an emphasis on public charging facilities. The authors analyze public charging infrastructure in the top electric vehicle markets globally, including a statistical analysis of the relationship between public charging and electric vehicle uptake. This study find that public charging infrastructure is a key to growing the electric vehicle market, there is no universally accepted benchmark or global threshold for the extent of charging required. This work corroborates other research that indicates the importance of developing charging infrastructure in unison with electric vehicle deployment. Multifaceted and collaborative approaches have been most successful in promoting early charging infrastructure build-out. Governments at the local, regional, and national levels around the world have used varied strategies to promote public and private charging infrastructure. This study also raises additional questions for future research. The analysis focuses on public charging, but more research into home, workplace, and fast charging availability is needed to create a fuller understanding of the complex charging ecosystem.
