FHWA has outlined areas in which today’s nascent development of EV charging infrastructure — which has evolved on an ad hoc basis mostly by private industry — must be improved on a national scale if states are to use $7.5 billion in bipartisan infrastructure law money earmarked to increase public use of EV charging and alternative fueling facilities.

“Currently, there are no national standards for the installation, operation or maintenance of EV charging stations,” FHWA stated in its June 22 notice of proposed rule-making and comment solicitation.

It added that “wide disparities exist among EV charging stations in key components, such as operational practices, payment methods, site organization, display of price to charge, speed and power of chargers, and information communicated about the availability and functioning of each charging station.”
