BMW i ChargeForward Program to demo contribution of intelligent EV charging to grid efficiency
January 05, 2015
At the Consumer Electronics Show in Las Vegas, BMW announced the BMW i ChargeForward Program—a pilot study to be undertaken by the BMW Group Technology Office, together with Pacific Gas & Electric Company (PG&E). Working with a select group of BMW i3 drivers, BMW i ChargeForward will demonstrate how intelligent management of electric vehicle charging can contribute to improved electric power grid efficiency while reducing total cost of electric vehicle ownership.
BMW i ChargeForward is designed to explore how to better match the impact of electric vehicles with other dynamic energy supply and demand sources. The study has two parts, a managed charge pilot program involving BMW i3 owners and a battery second life energy storage system. In the managed charge pilot program, select BMW i3 owners will allow PG&E to request a delay in the charging of their vehicles by up to an hour, when grid loads are at their peak. The program also includes a “second life” for used MINI E batteries, by repurposing these batteries into a stationary solar-powered electric storage system located at the BMW Technology Office in Mountain View, California.

The US Department of Energy (DOE) has released a report detailing the findings from six utilities which evaluated operations and customer charging behaviors for in-home and public electric vehicle charging stations. The work was done under the DOE’s Office of Electricity Delivery & Energy Reliability’s (OE) Smart Grid Investment Grant (SGIG program).
This report provides the results of these SGIG projects to help individual utilities determine how long existing electric distribution infrastructure will remain sufficient to accommodate demand growth from electric vehicles, and when and what type of capacity upgrades or additions may be needed. The report also examines when consumers want to recharge vehicles, and to what extent pricing and incentives can encourage consumers to charge during off-peak periods.
California to award up to $4M for projects to advanced smart charging and V2G technologies
December 19, 2014
The California Energy Commission has issued a solicitation (PON-14-310, Driving the Integration of Electric Vehicles to Maximize Benefits to the Grid) to fund Applied Research and Development projects that will advance technologies and strategies for smart and efficient charging and vehicle-to-grid communication interfaces that will provide maximum benefits to both the electricity grid and the plug-in electric vehicle (PEV) market.
There is up to $4 million available for grants awarded under this solicitation. The minimum funding amount for each project is $500,000; maximum funding amount is $1.5 million. Match funding is not required for this solicitation; however, applications that include match funding will receive additional points during the scoring phase.
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.

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.
