The charge would typically allow a 2013 Leaf to travel about 64 miles. SOURCE: Copyright 2010 by the eVgo Network; licensed under Creative Commons 2.0 (CC-BY-2.0).

Wireless Charging

In its final report, the committee will consider the possibility of charging a PEV wirelessly. Instead of sending electricity through a cord plugged into a vehicle, the energy in wireless charging is transferred inductively from a coil attached to an electricity source to a coil attached to the vehicle; both coils are encased and out of sight below the vehicle. Although that technology is not yet widely available to consumers, wireless charging systems are in the early stages of production and availability, and new designs are being investigated (Electric Vehicle News, 2011; Plugless Power, 2013). The reduced efficiency and increased cost of wireless chargers are disadvantages, especially considering that little time is required to plug in a PEV. However, the advantages of increased convenience and reduced susceptibility to vandalism might eventually be more compelling.
