On Wednesday, state officials in Washington broke ground on their portion of the West Coast Green Highway, which will eventually link the entire I-5 corridor with public-access electric vehicle recharging stations.
The site of the state´s first DC Fast-Charging station is Bellingham´s Sehome Village Shopping Center. Most of the stations will be located at private retail centers like this one, as well as normal re-fueling stations and travel centers that provide easy access to the highway.
In Washington state, EV stations will be located every 40-60 miles and will be equipped with both Level 3 DC Fast-Charge and Level 2 ´medium-speed´electric vehicle chargers. The new DC Fast-Charging stations are capable of recharging a Nissan Leaf or similar model in about 30-minutes, while the ´medium-speed´chargers will provide a slower 4-6 hour charge.
Last July, we reported that Washington State´s DOT had partnered with electric vehicle charging station manufacturer AeroEnvironment to provide, install, and operate the equipment for the charging stations. It´s not entirely clear yet how subscriptions will work or how much it will cost to use the stations – pricing will be established by the company.
Only the slower Level 2 rechargers have adopted a standard plug (J-1772), which means that vehicles like the Ford Focus, Nissan Leaf, and Chevy Volt will be able to use them. The ability to use the Level 3 DC Fast-Chargers will depend on the vehicle, since no standards have been adopted yet.
Washington´s network of chargers is slated to be operational by spring 2012, ultimately enabling EV owners to travel the length of the state between Canada and Oregon, 276 miles.
