Siemens, Duke Energy and Ford demonstrate lower cost home smart charging technology for plug-ins; due on market next year

December 05, 2014

Siemens Energy Management Division has teamed with Duke Energy and Ford to demonstrate the results of an 18-month effort to reduce the cost and expand electric vehicle charging technologies. Held at the Duke Energy Envision Center in Erlanger, Ky., and utilizing a Ford Fusion Energi Plug-In Hybrid, Siemens provided the first UL-approved residential electric vehicle supply equipment (EVSE) to demonstrate the ability to monitor status, report energy use, and be controlled locally from the local area network and from the cloud.

In 2012, Siemens was awarded $1.6 million in development funding from the US Department of Energy (DOE) to support research aimed at significantly reducing the current costs of electrical vehicle (EV) chargers and developing “smart” charging capabilities that support power grid efficiency and consumer demand.

Nissan begins testing combination of LEAF EVs and “LEAF to Home” for grid demand response services

October 16, 2014

Nissan Motor Corporation has begun testing in Japan of a system to use electric vehicle technology to help power grids cope with peaks in demand.

Nissan is using Nissan LEAF EVs paired with the LEAF to Home power supply system (earlier post) for demand response testing at several of its sales outlets run by subsidiary Kanagawa Nissan Co., Ltd. to assess the effectiveness of EV batteries when used for energy management. The tests are being conducted by ENERES Co., Ltd.

EPRI and partners to stage public demo of Open Vehicle-Grid Integration (VGI) Platform software

October 14, 2014

The Electric Power Research Institute (EPRI), along with several auto manufacturers, utilities, and regional transmission organizations, will demonstrate the Open Vehicle-Grid Integration (VGI) Platform software system, developed by EPRI and Sumitomo Electric Industries. The software is an advanced software platform for integrating plug-in electric vehicles (PEV) with smart grid technologies. (Earlier post.)

The live demonstration will showcase demand response and load curtailment capabilities through a single standards-based interface. The demonstration will involve 8 EV manufacturers, and attendees will include representatives from the state and federal public agencies involved with clean energy and transportation technologies, as well as the utility and automotive industries.

EPRI, 8 automakers and 15 utilities to create an open grid integration platform for plug-in electric vehicles

July 29, 2014

The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and to demonstrate an open platform that would integrate plug-in electric vehicles (PEVs) with smart grid technologies enabling utilities to support PEV charging regardless of location. The open platform will simplify and streamline V2G (vehicle-to-grid) communications, enabling PEVs to provide grid services and increasing the overall value proposition of plug-in vehicles.

The goal of this program is to develop a cloud-based, central server that would receive grid requests from a utility—such as Demand Response—and then translate and standardize that request so it could be relayed to all appropriate plug-in vehicles in the designated area. Automakers would be expected to develop and deploy technologies compatible with these smart grid communications.

The University of California, Riverside is opening its Sustainable Integrated Grid Initiative to research the integration of: intermittent renewable energy, such as photovoltaic solar panels; energy storage, such as batteries; and all types of electric and hybrid electric vehicles. It is the largest renewable energy project of its kind in California.

The first two years of operation is supported by a $2-million contract from the South Coast Air Quality Management District, awarded in January 2012. Construction of the initial testbed platform was also supported by an additional $10 million in contributions from UC Riverside and private partners. The testbed, which is located at UC Riverside’s Bourns College of Engineering Center for Environmental Research and Technology (CE-CERT), includes:

DOE issues draft loan solicitation for up to $4B for renewable energy and energy efficiency projects; drop-in biofuels a key area

April 16, 2014

The US Department of Energy (DOE) issued a draft loan guarantee solicitation for renewable energy and energy efficiency projects located in the US that avoid, reduce, or sequester greenhouse gases. The Renewable Energy and Efficient Energy Projects Loan Guarantee solicitation is intended to support technologies that will have a catalytic effect on commercial deployment of future projects, are replicable, and are market ready.

When finalized, the solicitation is expected to make as much as $4 billion in loan guarantees available to help commercialize technologies that may be unable to obtain full commercial financing.

A team from Fraunhofer Institute for Industrial Engineering IAO, together with Daimler AG and the Institute for Human Factors and Technology Management at the University of Stuttgart, is developing both the charging infrastructure and the energy management systems required to manage large fleets of EVs in a project called charge@work.

The aim of charge@work is to design a micro smart grid (MSG) capable of supplying the EV fleet with electricity produced exclusively from renewable sources. This year will see the installation of a photovoltaic unit and a small wind power system at the Fraunhofer Institute Center Stuttgart IZS, where up to 30 electric vehicles at a time can recharge at AC charge spots in the Fraunhofer Campus parking garage.

Sumitomo installs first large-scale power system using used EV batteries

February 08, 2014

Sumitomo Corporation has developed and installed the first large-scale power storage system which utilizes used batteries collected from electric vehicles. This commercial scale storage system, built on Yume-shima Island, Osaka, will begin operating in February 2014.

Sumitomo Corporation created the joint venture company, 4R Energy Corporation, in collaboration with Nissan Motor Co., Ltd. in September 2010, to address the secondary use of EV lithium-ion batteries. (Earlier post.) The used EV batteries that will be recycled into this large-scale storage system have been recovered and have gone through thorough inspection and maintenance at 4R, to confirm safety and performance. This prototype system (600kW/400kWh) consists of sixteen used EV batteries.

Honda joins vehicle-to-grid technology demonstration project in partnership with University of Delaware and NRG Energy

December 05, 2013

Honda has joined a demonstration project for experimental vehicle-to-grid (V2G) technology aimed at providing a potentially valuable energy storage resource to the electrical grid while providing for more cost-effective ownership of plug-in electric vehicles.

The Honda technology builds off of the research conducted by the University of Delaware and now supported by NRG Energy, Inc. through their eV2g joint venture (earlier post). eV2g came online early in 2013 with the first revenue-generating vehicle-to-grid project, demonstrating the controls, regulatory requirements, and market participation rules for selling energy storage from vehicles into the PJM Interconnection Regulation Market.
