Drivers of electric cars can now charge their vehicles at the public parking lots at Philadelphia International Airport, the Philadelphia Parking Authority announced.Seven stations capable of charging 14 electric vehicles at any time have been installed: two on Level 1 in Garage C, two on Level 1 in Garage D, and three in the Economy Lot next to the airport toll plaza.

Charging will be free until April 1. After that, rates may still be free, or there may be a $1 to $5 fee above the normal cost of parking in the lots, said Parking Authority spokesman Martin O'Rourke.

The plug-in and charge stations will be operated by ChargePoint. More information is available on the ChargePoint app or at www.chargepoint.com. The Parking Authority operates the public parking lots at Philadelphia airport.
