Vehicle to Grid (V2G) technology is a bi-directional grid interface for gridable vehicles such as Battery Electric Vehicles and Plug-in Hybrid Electric Vehicles. It allows such vehicles to use excess battery power to help load balance localized grid segments durring peak load periods. These vehicles can then be recharged durring off peak hours at cheaper rates while helping to obsorb excess night time generation. Electric power transmission is the second process in the delivery of electricity to consumers. ... An electric vehicle is a vehicle that is propelled by electric motors. ... A plug-in hybrid electric vehicle is a hybrid electric vehicle which has additional battery capacity and the ability to be recharged from an external electrical outlet. ...
Many Electric vehicle conversion owners, who's battery of choice is still PbA which have limited cycle lives and capacity, would prefer using their battery investment to driving their cars rather than help load ballance the grid. Future battery developments [1] (http://www.toshiba.co.jp/about/press/2005_03/pr2901.htm) could change the economics making it advantagious to use high capacity and cycle life batteries in BEV/PHEV's for grid load balancing and as a large energy cache for renewable grid resources. Even if cycled daily such batteries would only require recycling every 55 years or so. Since BEV's can have up to 50kWh worth of battery storage they represent somewhat more than the average homes daily energy demand. Even without a PHEVs gas generation capabilities such a vehicle could be utilized for emergency power for several days. As such they may be seen as a complimentary technology for intermitent renewable power resources such as wind or solar electric. Wikipedia does not have an article with this exact name. ...
