GE, Nissan sign R&D agreement to fast track broader adoption of electric cars

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 such as the Nissan LEAF.

GE and Nissan have identified two key focus areas for the research efforts: the first relates to the integration of electric vehicles with homes and buildings; the second looks at electric vehicle charging dynamics and the future impact on the grid once millions of electric cars are on the road.

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 vehicle 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, including:

  • 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?
  • 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 vehicle 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 vehicle 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 vehicle charging needs without over-stressing the grid.

GE’s work will be conducted primarily at its global research operations in Niskayuna, New York. Nissan Technical Center North America, located in Farmington Hills, Mich., will lead the automaker’s efforts, including integration of vehicle-to-home charging technology, with support from the Nissan Advanced Technology Center in Japan.



Since most electrified vehicles will be used about 2 hours per day or less, it would be surprising to see how well managed 100 + M V2Gs could stabilize the grid, maximize energy distribution and contribute to users benefits. To sell power at $0.30/Kwh during peak demand periods and be able to recharge at night at $0.05/Kwh or off-peak at $0.10/Kwh could be interesting.

Availability of a fully charged 24+ Kwh battery could be very useful during power outages.


Based on the Renault battery lease figures, travelling 1 mile costs around 11 cents in battery depreciation.
Using 3 miles per kilowatt, close to the Leaf average in actual use, you would pay 21 cents to store 1 kwh in battery depreciation.
Plus the off-peak rate of $0.05 kwh that comes to $0.26 kwh cost to offset against the $0.30 you pay for peak power.

Doesn't sound like much of a business to me.


Utility energy buy back is key to solar home systems also.


Capital cost of V2G is another consideration. The monitoring and safety components of the hardware will further reduce profitability of stored energy. But it is good to see these two companies partnering on EV transport.

Regardless of how the electrical energy is generated - there is a huge future in electrified transportation. Never having to go to a third party for transport energy (i.e. gas station) will revolutionize contemporary life.


DaveM...what if future improved ultra-caps-batteries cost drop to less than $250/Kwh instead of $1000+/Kwh and if they could be quick charged 10000+ times instead of the current 1000 times? That is what could very well happen by 2020 or so. What is not currently too beneficial may become a gold mine 10 years down the road.
