Charging stations for plug-in electric vehicles are a rapidly growing amenity being added to workplaces across California and the United States. Numerous workplaces have installed stations for their employees and visitors to use. These decisions have been supported by a recent Idaho National Laboratory study, which concluded that “”charging infrastructure should be focused at homes, workplaces and public ‘hot spots’ that serve multiple venues. When charged by drivers, battery electric and plug-in hybrid electric vehicles achieve significant petroleum reductions while meeting the public’s everyday driving needs. Through workplace charging installations, businesses have learned new lessons and established best practices. Workplaces have researched charging options and developed plans, chosen appropriate charging systems, followed installation directions and established policies and procedures. Many workplaces are continuing their efforts by evaluating their plans. New challenges and creative solutions have emerged as more charging stations are being installed and workplaces plan for future growth. This document describes some of these challenges and shares solutions developed by workplaces. Each section provides guidance and highlights additional resources and tools developed to complement the guidance.
