Many barriers to electric vehicles are incrementally being overcome. Falling battery costs help address the initial cost barrier and increasing availability of electric vehicle models of different types is attracting more prospective vehicle owners. The development of sufficient charging networks, however, is a work in progress. Although regular at-home charging remains one of the great advantages of electric-drive technology, it does not fulfill every charging need, and a mix of workplace charging, public charging, and fast charging is needed to extend range and increase charging access to those customers with no home charging.

Our report focuses on lessons learned from fast-charging deployments in many markets around the world through mid-2018 and on the usage by battery electric vehicles (BEVs). The report reviews recent developments in fast-charging technology and also the amount and distribution across major electric vehicle markets. The study also summarizes research into the impacts on the electric grid under increasing electric vehicle demand, and approaches to mitigate any associated issues. We also review planning issues related to fast-charging station use and siting strategies, as well as cost and business cases for the deployment of fast-charging stations. Based on this review, we make several conclusions and present several associated policy implications.
