There is a problem in installing a charging station near the gasoline pumps. To do this, the charging station and EV shall have to be a Class I, Division I explosive proof installation. There shall be no standard enclose electrical systems in with 20 feet from any dispensing systems that emits a explosive atmosphere.
Even in service bays and garages, the standard electrical receptacles, switches and other electrical items, shall be not less than 4 feet above grade. In auto service bays all electrical below 4 feet shall be a totally enclose explosive proof enclosure. Conduits raising from floor level to above 4 feet grade shall have a seal off in series with the conduit, to prevent fumes to enter a non-explosion proof electrical device. Then there is another distance of up to 30 feet with no standard totally enclose electrical enclosures below four feet at voltages up to 600 volts. Over 600 volts, the distances is increase to 50 feet or 100 feet total and not lest than any open conductors such as power lines that are not less than 50 feet above grade. Lets say a EV parks in parking area, where the distance is close to a gas pump which is dispending fuel and fumes. Your EV does not even have to be charging to cause a explosion which could be cause by open contactors closing during start up.
