The American Automobile Association will begin deploying electric-vehicle mobile charging units this summer with the help of its roadside assistance fleet, to help drivers of electric vehicles such as Nissan Motor Co.'s Leaf and Cheverolet Cruze recharge their car batteries.

The American Automobile Association said it will unveil its new mobile-charging trucks and provide more details on its plans next month at the Plug-In 2011 Conference & Exposition in Raleigh, North Carolina.

The association said it is expected to begin initial deployment in select cities across the country later this summer to address the concerns of the emerging electric vehicle market.

The unit is set to be fully unveiled in July and will be in action on US roads later in the summer, a spokesperson for the AAA said.

The units will be rolled out to California, Oregon, Washington, Florida, Tennessee and Georgia, the association said.
