Wawa, Buc-ee’s and Busy Bee have come together over the slow rollout by Florida and about a dozen other states of a federally funded electric-vehicle charging stations program. Introduced three years ago, the $5 billion National Electric Vehicle Infrastructure, or NEVI, program allows chargers to be built by private entities, if the owners put up a 20 percent match. But Florida is among states that have not issued requests for proposals on the charging program, according to a report by Route Fifty, a sister publication of The News Service of Florida.
