Robust Public Charging Infrastructure Is Essential for EV Adoption

Overnight charging is not an adequate solution if EVs are eventually going to supplant internal combustion engine (ICE) vehicles entirely. The realities of who buys new or used vehicles and where those people live will play a huge role in determining how EVs proliferate throughout the transportation fleet. Expansive and reliable public charging infrastructure will be an essential element of developing a successful e-mobility ecosystem.

Ultimately, the goal is to provide all drivers with equitable access to charging, similar to the current ICE fueling ecosystem where anyone can pull up to any pump, anywhere in the country, and pay relatively the same price for fuel—getting it in the same amount of time—as anyone else. This will require a diverse charging landscape with public charging that is convenient and affordable everywhere, at varying speeds, to accommodate the needs of every driver. This will require developing DC fast charge networks, providing curbside and workplace charging, and making home charger installation more affordable.

In this thought leadership paper, the Guidehouse Insights Transportation & Mobility team explains how a lack of fast charging that the public can easily access is a barrier to EV adoption and suggests policy measures that could help rectify that situation.
