V2Green’s vehicle-to-grid management technology (earlier post) will be used to monitor the performance of 13 plug-in hybrid electric vehicles (PHEV) in a Seattle demonstration project and control their charging.
Under a contract with the US Department of Energy’s Idaho National Laboratory, V2Green will provide a logging system to collect real-time vehicle performance data provided by the V2Green Connectivity Module (VCM) installed in each PHEV. A cellular modem will upload the data to the V2Green server where it is archived and made available for the Idaho National Laboratory’s analysis.
The lab will monitor fuel efficiency, electricity usage and other vehicle performance measures on each of the 13 converted Toyota Prius PHEVs.
Seattle City Light will operate three of the vehicles in the test. The City of Seattle will have one. The Port of Seattle will get two and the Puget Sound Clear Air Agency will get three vehicles. King County will test four plug-ins.
In addition to monitoring vehicle performance, V2Green’s technology also provides the capability of smart charging. By providing intelligent, two-way communication between plug-in vehicles and the electric grid via the VCM, Seattle City Light can control the timing, pace and extent of vehicle charging within driver-specified requirements. The utility can control its load requirements, ensuring that charging takes place during light load hours, protecting the distribution system and avoiding the need to buy power.
We believe this project will show how plug-in hybrid technology can reduce our dependence on oil and cut greenhouse gas emissions that contribute to climate change.—Seattle City Light Superintendent Jorge Carrasco
Seattle City Light is the city’s municipal electric utility.
V2Green technology also is being used to test two plug-in hybrids in Austin, Texas, and six from the fleet of Xcel Energy, using similar smart charging and data collection capabilities.
