SEATTLE — Electric car drivers are increasingly plugging in and charging up at Washington state’s network of public car-charging stations, according to new data from the Washington state Department of Transportation.
But while drivers report line-ups at some heavily-used stations along Interstate 5, other electric-vehicle charging sites on the state network are rarely getting used, the data show.
Since May 2012, when the first fast-charging station began operating in Washington as part of the so-called West Coast Green Highway, drivers have used the state’s 14 charging stations more than 10,000 times. Monthly usage for all those sites doubled to 1,125 charging sessions last September from 528 the previous September.
