Hotels catering to business travelers are rushing to install the hot new amenity: electric vehicle chargers. A perk that will become only more important as the rental car companies increasingly replace their fleets with electrics, at this point 26 percent of U.S. hotels have an EV charger, according to a recent survey of 17,000 facilities by an industry trade group. Depending on the place within the hospitality sector one finds oneself, that can be as high as 90 percent of hotels in the luxury category having a charging station or as low as 20 percent of hotels within the limited service sector. Hilton, which has 5,900 locations in the U.S., is adding 20,000 charging points at 2,000 locations on top of the 1,850 locations that currently have chargers, while rival Marriott has chargers at 1,200 of its 5,900 locations as of last year and is looking to add much more.
