Electric car batteries can now power home appliances

By | February 22, 2011, 11:54 PM PST

The lithium-ion batteries used to power electric cars are still relatively new. But as the technology steadily improves, the units may soon be relied upon to power more than just vehicles.

Sharp Corporation has unveiled the Intelligent Power Conditioner, which enables electric vehicle batteries to be used as a source of electricity for electronics around the home. In tests, researchers used a battery pack from an electric vehicle to provide 8 kilowatts (kW) of power, enough to power the kind of appliances found in an average household. The Intelligent Power Conditioner also delivered 4 kilowatt hours (kWh) of energy for the recharging of the electric vehicle’s battery pack, a process that took about half an hour.

The device will undergo further testing to demonstrate that this kind of system can be used safely and reliably before it can be made available to consumers.



The Intelligent Power Conditioner is a major component of a larger project known as the Sharp Eco House, a concept designed to reduce a home’s carbon footprint through the implementation of green technologies such as solar cells, storage batteries and direct current appliances. While solar cells do a sufficient job of harvesting energy from the sun, the company is developing an interconnected system of storage batteries that they say will play a vital role in  storing the energy efficiently and making it readily available during the evenings, rainy days and other off-peak periods.

The power inverter/controller device will allow for both solar cells and storage batteries to be integrated along with standard utility power to ensure that electrical energy is supplied steadily throughout the house. The device can also be integrated with direct current home appliances and supply direct current electricity.

Why?
Except in a disaster recovery situation, why would anyone want to run appliances off his or her car?

All you are doing is back feeding the house grid as many people do with a generator plugged into a dryer outlet during a power outage.

I think the headline would have been better if it stated the obvious.

Consolidated power management solution can manage your solar or grid power, charge your EV or turn your hybrid car into an emergency generator.

RE: Electric car batteries can now power home appliances
people in the dominican republic have been using batteries for many years. they're called "inversores." the electric grid is not dependable, and brownouts are common. many people have installed a set of batteries that charge when there is power. as soon as the lights go off, the batteries go on for a temporary replacement. some people have an additional backup: after the batteries go online, and if power fails to return, the system automatically starts up a gasoline generator, which keeps the light on for a longer time.

'battery goo' for electric cars
"Electricity is nothing like gas. You can't just pump a tank full of it into your electric carparts, which means that we're reduced to lengthy charge times or inefficient compromises like battery swap stations. MIT researchers may have come close to solving this problem with a battery goo that you can pump just like gas.

You made my point.
So the headline is wrong.

My UPS does the same thing.

RE: Electric car batteries can now power home appliances
Batteries for home power have always been the showstopper. Cost is the big issue. Most batteries in the past have had a relativly high cost over time. Replacement time is around 3 years, cost is about $60,000.00. That means budgeting about $20,000.00 a year to live off the grid. Wind/Solar have been the traditional generation sources.

I haven't seen the cost figures for this one, but if it is higher than $4,000.00 per year, it will be a non-starter except in a very few situations. Cost will determine if this flies or crashes.

Grid costs are about $3,000.00 per year where I live, for comparison.

RE: Electric car batteries can now power home appliances
This system is separate power distribution. Using grid to charge it
then distribution is made to home and car. In case of blackout car
can be backed. No harm in that given it can light your home. I
read of a guy that uses a solar panel to charge a car battery then
takes it in his home and hooks to inverter and powers his
electronic, all because he burnt out a receptacle. Anyways this unit
would only be most beneficial if linked with solar panel and a few
capacitors to hold extra power before and after the source to
prepare for surges cause by refrigeration unit motors. Its said
there is such capacitor available and can cut home costs by
elimination or these surges.

The eco crowd refuses to admit the obvious.
If solar truly were affordable to install more people would do it to avoid the higher price of daytime electricity in many states.

Florida has constant issues with meeting electric power needs during hot summer days when the a/c is running all of the time and they charge more for electricity in the daytime because of that problem.

An affordable household power management system that would dynamically adapt to the flow of power from sources like solar and the grid would make solar power acceptable to many people.

On a sunny day the system would pull power from the solar panels to power the house and feed excess to the grid. After dark it needs to dynamically switch to grid power.

It is not the 100 percent replacement that the eco crowd wants, but in theory it could cut a regions use of coal-generated electricity in half or more on any sunny day. I would call that a big savings.

By eliminating the need for batteries you meet in the middle and produce an affordable system that makes a big impact on the environment and peoples wallets.

This setup would also require more of a smart grid mentality from the power generation companies to match production to demand based on weather and time of day.

Complex, yes, but not unmanageable or impossible. Nuclear power fits nicely into this scheme.

RE: Electric car batteries can now power home appliances
I have been talking about this with friends... Why pay a lot of
money to feed electricity into the grid when you could store the
12 volts at home in deep cycle batteries. Motorhomes have been
doing it for years. We have satellite TV and all the other modern
conveniences that run from 12 volt.
To cost of feeding the mains system with solar power is
increased substantially by the cost of an inverter. Why not divert
that cost into deep cycle batteries and a stand by battery charger
(in case of prolonged overcast weather)
The introduction of LED lighting improves current drawn from
batteries significantly and using 12 volt at home eliminates the
problems associated with higher voltages.
I love it... and can see a time when it will be the norm...

@ucdailoi@ We have satellite TV and all the other modern

I think your 12VDC TV is a 12 or 15 inch Standard Definition model and NOT the 52 inch High Definition model you are used to at home now.

And the 12VDC refrigerator would have to be measured in cubic inches to give you a number even close to the numbers that you are used to at home now. Well that ci number should be divided by 2 or 3 to be honest, but you get the idea. And if you pay more $$$ for it you can get one that runs on LPG or LNG, but that may not be cost effective.

Cost effective
The main problem now is it is not cost effective to convert to solar or wind.

Home power system
8kw should be good. Now if they will match it with a proper gasoline or propane generator to charge the batteries I'll buy!
