Residential charging in single family homes is the most prevalent, convenient, and generally lowest cost charging method for Plug-in Electric Vehicles (PEVs). It is PEV charging at its most basic form and at its highest level of importance. All other forms of PEV charging, such as charging at workplaces, multi-dwelling units, and public venues should be judged against residential charging relative to need, cost and convenience for widespread PEV adoption to take hold.
Workplace charging is often considered next in importance to residential charging. To take its rightful place, however, we must solve the economics, logistics and planning issues. For example, if workplace charging is too expensive, a driver with a long commute may decide not to buy a PEV. This paper discusses the benefits of focusing on low-cost, robust charging for the workplace, and the need and method to prepare a long term infrastructure build out plan.
