In the largest installation of commercial electric vehicle chargers at an airport in the United States, Portland International Airport now has 42 L1 PowerPost EV charging stations in place.
PowerPost commercial electric vehicle charging stations (EVSEs) are designed and manufactured by Telefonix Inc., a technology design and manufacturing company that creates product solutions for highly regulated industries.
Portland International Airport chose PowerPost level 1 electric vehicle charging stations for their integrated, retractable cord reel, which keeps cables off the ground, reducing maintenance and tripping hazards.
They were also selected because they are level 1 units, which have low current requirements and allow for an efficient use of energy. Level 1 charging is well suited for long-dwell parking that is typical at airports and workplaces.
The low-current requirements of level 1 also allowed the airport to install more charging stations, compared to more powerful chargers that often require costly upgrades to the electrical supply.
Level 1 charging enables EV drivers to recover about 5 miles of range for every hour they are plugged in. The range lost in a typical commute of twenty miles is recovered in about 4 hours at a cost to the facility of less than 75 cents.
The PowerPost EV charging stations will be free to use for employees and visitors.
