Electric Cars as Part of an Integrated Household Power System

Yes perfect for the nuclear powered car....Since it remains on all the time it could provide energy for the household without fear of running down any battery bank, in fact it could charge a battery wall for when the car is in use as transportation...

...or maybe your new home is on wheels and charges your car....

This is an idea people are contemplating with a fully smart grid approach.

Begs the question of timing. The battery is supposed to be charged at some point, best before you take off for the next ride.

Timing for charging would shift to late hours probably but this begs the question of infrastructure. Is the existing network ready, to take and give energy when needed?

Can we charge all cars in the night or will there be overload? Would we use battery charge from one vehicle to charge the other one? How smart can you make the grid with a multitude of cells simultaneously having make a decision to load or unload???

Begs the question of battery technology up for more charge recharge cycles.

Sorry no flowers for this one, but some merits to think about it.

Yep, the grid was designed to be one-way only. Significant numbers of two-way customers would surely confuse and possibly damage today's grid. The bright side is this will provide many years of employment for EE's. And unfortunately for lawyers too.

It may have been designed that way, but rooftop solar, especially here in Australia where we now have in excess of 5.4 megawatts of solar in-feed installed (16.5% of our homes now sport PV co-generation of less than 10kW each, but which in total accounts for around 4.6MW) shows that the grid can handle it.

Our electricity grid appears to be having no trouble coping with this input, and it actually has a beneficial effect by spreading out generation over much larger areas, thus reducing power line losses.

The problem here is that some politicians have totally unrealistic expectations of renewables to be able to reliably supply base loads, thus the recent spate of blackouts due to coal and gas fired generator closures.

Provided appropriate anti-islanding arrangements were in place there would appear to be no logical reason why sufficiently charged electric vehicles could not be utilised to feed back to the grid, although this would possibly be more appropriate for Hybrids as they can recharge themselves to some extent, whereas fully electric vehicles would still require charging from some source and, if that were to be the grid, then the nett result would be a loss.

Maybe utilising the free charging stations and then selling that back to the grid would be a sneaky option, but would likely soon result in cessation of the freebies.

This has been done.

Yeah a little pricey for $.50 per kwh, which is also a little pricey....The largest size 4kw for about $2500. + install and peripherals, falls short for some major appliance needs, most notable A/C units and electric heat....

A stand alone 4kw pure sine wave inverter generator can be had for $1500..and I think with UPS battery backup on your computers, you could get along with a cheaper larger generator for a few hundred dollars....

Not to hijack my own thread, but I have small UPS's on our computers and our TV. We experience brief outages (a few seconds to a minute) which don't warrant getting a backup generator, but can scramble electronics.

I have them on all my tv's, cable boxes, sound systems and computers as well, for the same reason...

Stan Lee got a futuristic idea

I just don't know if this can be done or even possible. But, it's impressive.

This concept has been around for years. It is called Vehicle to Grid (V2G), and technology is being developed in order to achieve it.

I attended a talk by a researcher working on V2G at the University of Delaware a few years ago. My only concern with it was the extra charge / discharge cycles while it's grid connected. Interesting concept though.

There is a loss due to the efficiency of charging the batteries, and a loss in getting the power out. It would be good for a backup system, otherwise it's a waste.

Energy storage in rechargeable batteries is established technology. In principle, one does not need to surround a battery with the structure of a car in order to use the battery for other services; in principle the economics of investment would suggest otherwise.
