GE unveiled its GE WattStation, a residential electric vehicle (EV) charger, which aims to help accelerate the adoption of plug-in EVs by decreasing time needed for vehicle charging and—using smart grid technology—allowing utilities to manage the impact of EVs on the grid. (At this time, it appears only available in the States.) On average, the GE WattStation’s charging time is four to eight hours (assuming a full-cycle charge for a 24 kWh battery). GE WattStation will be commercially available globally in 2011. In May 2010, GE Global Research and Nissan signed a separate three-year Memorandum of Understanding (MoU) to explore new technologies that are needed to build a reliable, dynamic smart-charging infrastructure.
