GE and Nissan have signed a two-year research collaboration to speed up the development of a reliable, robust smart charging infrastructure to fuel mass market adoption of electric cars.
GE and Nissan have identified two key focus areas for the research efforts. The first relates to the integration of electric cars with homes and buildings. The second looks at electric car charging dynamics and the future impact on the grid once millions of electric cars are on the road.
The R&D agreement connects leaders in two major industry sectors that will work together to increase adoption of electric cars. With more than 25 percent of the world’s electricity generated or distributed by GE equipment, GE brings its considerable expertise of the power grid infrastructure to help address the global challenge of integrating millions of electric cars onto the grid.
With the all-electric Nissan LEAF, Nissan is the leader in zero emission cars, developing new technologies and partnerships to speed mass market adoption of electric cars and to ensure their successful integration into the grid.
Several projects around the two focus areas already are underway. In one project, researchers from the companies are studying how electric cars like Nissan LEAF can be incorporated into GE’s overall concept for a Smart Home.
Nissan engineers are developing methods to connect the car to the home, making it a more integrated part of the building’s energy equipment. This project will look at how the addition of an electric car impacts the cost of electricity and changes overall home electricity loads.
In another study, researchers will use aggregate usage data along with sophisticated simulation and modeling experiments, to analyze the effect millions of electric cars could have on our electrical distribution system.
For all of these projects, researchers will be seeking answers to a number of important questions. They include:
How can smart energy management systems for homes and buildings be leveraged to support the management of EV charging? How can we take advantage of energy storage and renewable power, such as home solar arrays, to reliably manage and meet the power needs of electric cars? For example, are there innovative ways to directly link charging stations with renewable power sources?
Nissan researchers are studying the use of two-way power flow between the car and the home, via its CHAdeMO quick charging port, as a method to reduce the home’s consumption from the grid during peak periods, or to utilize the car for emergency backup power. GE researchers have programs under way to understand how these systems, in tandem with the utility, could be used to meet car charging needs without over-stressing the grid.
GE’s work will be conducted primarily at its global research operations in Niskayuna, New York, where the latest electric transportation research and smart grid technology will facilitate research programs between the two companies. Nissan Technical Center North America, located in Farmington Hills, Mich., will lead the automaker’s efforts, including integration of car-to-home charging technology, with support from the Nissan Advanced Technology Center in Japan.
