More-electric cars and other vehicles create opportunities for control, extreme performance, energy reduction and flexibility, operating cost reduction, and emissions reduction.  Limitations that include limited range, battery performance issues, refueling time, and access to charging are often considered to be major drawbacks.  This presentation shows how most electric and plug-in hybrid vehicle energy needs can be met with Level 1 charging, the level of a conventional single-phase outlet. Safety protection, metering, communication, billing, and other functions can be supported by a car to turn a “dumb” single-phase outlet into intelligent vehicle charging infrastructure. Some of the considerations and strategies linked to this process are described. The actual needs and typical user interactions are discussed, showing some aspects of how Level 2 charging fits in.  Survey results in a campus setting help to support the concepts.  Grid support capabilities are discussed.  The ability to use conventional outlets has the potential to make electric vehicle charging infrastructure ubiquitous, with expansion at a fraction of anticipated costs. Charging coordination combined with flexibility can make electric transportation systems important partners for future electric power systems.
