Abstract:

This working paper identifies metrics that cities can use to track charging infrastructure policies and deployment to support electrification goals in cities. Using the most recent available electric vehicle and charging infrastructure data, this paper analyzes how electric vehicle per charger ratios are evolving, the relationship between public charging and housing type, and considers the contrasting needs for public charging networks in the early versus mature markets. Best practice policies to grow the charging infrastructure network are identified to illustrate how these lessons can be used to estimate future charging needs. This investigation into charging infrastructure patterns and future needs yields the following conclusions regarding data-driven assessment of charging infrastructure needs for cities: (1) Tracking and measuring charging infrastructure is a key first step in achieving future electric vehicle targets. (2) Much more charging will be needed to accomplish cities’ electric vehicle transitions. (3) Local factors dictate charging needs, making general international guidelines difficult. (4) Cities have a menu of policy options to accelerate charging deployment.
