Nissan has unveiled a new power supply system that allows electricity stored in the lithium-ion batteries of the all-electric Nissan LEAF to be supplied to a house. With the LEAF's batteries able to store up to 24 kWh of electricity, Nissan says the system could supply the average Japanese household with electricity for about two days. This would be enough to provide a stable electricity supply in the event of power outages or to allow consumers to store cheaper off-peak power for use in high demand periods.

Nissan unveiled the system at the 'Kan-kan-kyo' demonstration house built by Osaka-based homebuilder Sekisui House Ltd. in front of the Nissan Global Headquarters in Yokohama. The system connects the car to the house's electricity distribution panel using a connector linked to the LEAF's quick charging port. The connector complies with the CHAdeMO Association's protocol for quick chargers and allows the system to not only supply electricity from the vehicle but also to it for charging.

Nissan says the system will allow households to be supplied with a stable amount of electricity throughout the day and reduce the burden on the current power supply by charging and storing electricity in the LEAF with electricity generated at night or through sustainable methods such as solar and wind power, for use in high demand periods. The system uses a 200V single-phase three wire system and the operation display panel shows battery power, output voltage and output current, as well as allowing for switching the electricity charge between supplies.

The system will be compatible with existing Nissan LEAFs, and Nissan says it is continuing development and study of how the system can be fully aligned and connected with current power systems. The company aims to commercialize the system this financial year.

When you don\'t have power to your house do you really want your car to be immobile? What does it do to the life of the batteries?


This is a great idea for diesel-electric systems. When the power goes out and you're at home your car is most likely already plugged in because you plug in when you get home. It could even be cheaper and more environmentally friendly to generate electricity from a diesel-electric automotive system then buying it from the electric company. This is something all the auto companies should offer with their diesel-electric vehicles. It would make them much more attractive being able to serve as an emergency generator.

As for having a 100% electric car when the power system goes down is probably not a good thing. That's like having a gas running vehicle when there's no gas at the stations. You could power your house but then you won't be able to travel as far. If you can drive 10-15 miles and recharge somewhere else then go home then you're good to go.

Personally I think diesel-electric power system is your best bet for energy efficient vehicles until battery capacity doubles (that's why trains are still diesel- electric.) I thought tractor trailers would be next in line to adapt the diesel-electric power system technology as it only makes sense and can't understand why it hasn't caught on with tractors yet.

This will NOT work in Mississippi because there is NO way the Tax for Roads can be applied here. And we canNOT drive without paying tis tax...too bad.


Wow, you\'re a glass is half empty guy, aren\'t ya! :) I\'ve got solar panels on my house, but the only downside is there\'s no storage, so we gotta be on the grid at night. But with this, we could charge the car all day, then use the electricity at night. Brilliant.

so...how much for a spare battery pack to keep at home?

Wow this is god send if we can buy such vehicles and have our home powered this way!

In spite of my not hatred, but the stupidity of the "solar car racing" which pits heat stroking rider in a mobile solar powered pencil case against other teams doing the same stupid thing, having a SOLAR POWERED HOUSE (or my point - a car port with solar cells on the roof), as a massive collector, to SUPPLEMENT a smaller solar supply on the car - is exactly what I have been hammering.

WE NEED PRACTICAL DAY TO DAY TRANSPORT - for up to 2 or 4 people with a weeks shopping and all, in a single vehicle....

Here we have it - Now if only the car could be rigged to be picking up say 300 to 500 watts of power when parked in full sunshine., sitting there getting about 6 to 8 hours a day of power..... and being supplemented by the home supply for the longer commutes etc. we would have a VIABLE day to day solar powered form of transport that would meet the needs of most of the people most of the time.

Taking into consideration that some areas get pretty cloudy for extended periods and other areas have almost no could cover ever.... and there seems to be far more of that than not, (far more areas of NO cloud cover), the rest of the power can be distributed by the mains, from remote or other renewable resources.

John: When you are not at home or using much juice you lose all the extra? Why haven\'t you installed a storage battery to go with the solar collection? Or does the extra go back into the grid? If so, you don\'t need the Nissan because you are selling your extra.


Matt... My opinion is that the present day big business tycoons (like the former ones who brought in illegal labor as far back as the late 1800\'s for cheap labor, that now has grown into a serious economic burden to our country), once again only have interest in making the big bucks no matter the consequences, are attempting to keep all of us as \"energy prisoners\". Perhaps they are just trying to \"sell\" us another bill of goods encouraging us to build yet another infrastructure delaying product like natural gas. Ever hear of that former oilman turned natural gas promoter, T. Boone Pickens? He\'s just one of a cadre of (in my opinion) sheisters trying to turn the move to renewable alternative energy sources into profit only for them and another dead end for consumers.
