NREL study finds that uncoordinated plug-in vehicle charging could prove challenging to the grid

Green Car Congress

An influx of plug-in electric vehicles (PEVs) charging without coordination could prove challenging to the nation’s electric grid, according to research conducted by the US Department of Energy’s National Renewable Energy Laboratory (NREL). In this case, a problem arises when motorists gathered in a geographic area began buying these vehicles and plugging them in to recharge upon returning home—a practice known as uncoordinated charging.

One question that's frequently asked of many others too: Does recharging electric cars pose a threat to the electricity grid? Over the next 12 months, carmakers will introduce several new plug-in electric vehicles. The 2010 Fisker Karma and the 2011 Chevrolet Volt plug-in hybrids, among other electric-drive vehicles, are

SoCal Edison white paper shares data about PEV usage and charging

Green Car Congress

The paper, “Charged Up: Southern California Edison’s Key Learnings about Electric Vehicles, Our Customers and Grid Reliability,” shares information based on customer data and utility operations gathered since SCE began to prepare the distribution system and its customers for widespread electric vehicle (EV) adoption in its service territory. This could create new implications for grid reliability, which SCE is monitoring, it said. The grid is becoming much more dynamic.

Pike Research says lack of technical standards could hinder utilities’ readiness for EVs; forecasts $5.1B in spending from 2010-2015 on EV IT systems

Green Car Congress

Utilities will face a host of new infrastructure requirements to support the increased power demand that will result from customers plugging in to recharge. The majority of EV service equipment (EVSE) will be networked and managed via information technology (IT) and communications systems that will aggregate power demand and enable a coordinated response to changing grid conditions.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

At present, PHEV technology alone is equipped to improve the current electric grid. The car can refuel during periods of low demand on the grid, and if equipped with a bi-directional charger, can actually replenish the grid with excess energy gleaned from a renewable resource. Appendix G: Solar and Wind Grid Management using PHEV. Some of these, like the need for more efficient use of the current electric grid have not been addressed by other technologies.

Are You Plugged In?

Revenge of the Electric Car

Plug-in hybrids differ from hybrids on the road today in that they can go longer distances on battery power and can be recharged via electrical outlets. NEV stands for neighborhood electric vehicle, which can travel at a top speed of 25 mph. V2G stands for “vehicle-to-grid,&# a technology system being developed to enable electric cars to store power and sell it back to the grid. The Wall Street Journal assesses your EV readiness.

Infrastructure, recharging and business models. While OEMs and utilities continue to define and refine hardware standards and communication protocols for smart charging, a tremendous amount of work needs to be done in preparing both the grid and the process to accommodate the expected influx of plug-ins, and to make the process as easy as possible for consumers. The impact from plug-in electric vehicles on the grid could be very substantial.

Also, besides giving you the ability to charge at night when most utility rates are lower, future vehicle-to-grid (V2G) technology may allow you to sell some of your stored energy back to the utilities. Although charging infrastructure is beginning to find its way into cities, it may be awhile until they are available in residential neighborhoods en masse. The demands on the grid would require a lot of infrastructure work without some sort of "energy reservoir" in place.
