I would have avoided this post, but you seem to be replying to me. Maybe I\'ve made a mistake in that assumption and you are just airing out your fingers.

A post can be read and responded to by anyone. When I said \"And why do people say it costs tho.....\", you didn\'t seem to know who I was talking to, I can\'t tell to help you out now, since you snipped the attributions.

Many people talk about stuff they don\'t actually know much about. An EVSE which does zero energy conversion, costs around $400 for 5 kW handling capability.

You need to shop around. I can get one for half the price that does 8kW. Anyway they have electronics to communicate with the car.

One what? The point is the EVSE doesn\'t \"handle\" the power, it just connects the car to the power. An inverter is much more expensive because it has to actually convert the power. So no, $500 is not realistic for 10kW.

But you weren\'t talking about invertors, you said EVSE.

10 kW is around 42 amps. So I can see a 10 kW inverter being much more expensive than $500. If you think you can make and sell them at a profit, for $500, you need to go into that business!

A grand actually. https://www.ebay.co.uk/itm/193572450281

LOL!!! Anyone who would wire that Chinese junk to their car OR their house is an idiot! Maybe Ed Lee is up for the job?

Absolutely, i got a 3kW 48V to 220V for $99. 10kW for $999 is too expensive.

If you join the outputs together from three of those, would they phase synch?

One requirement is a power transfer switch. A 100 amp 240 volt single phase version on Amazon is just under $200. A 200 amp version is just under $600. Add in a few dollars for the fittings, wire etc. There was a rule of thumb years ago that parts and labor would be about the same amount. You\'d hit a thousand dollars without much trouble. I\'d bet labor would be higher because one would probably have to take things apart before installing the new.
I don\'t know the additional requirements the National Electrical Code (U.S.) would impose for standby power.

I addressed reasons why 10KW is a reasonable number in my other post, but you got me thinking
of another factor. The wiring in a home for EV charging is almost always going to be 50A
tops, at least as of today. That\'s 12KW.
If you have 24kW in the house, you might aswell fit a charger as such.

Now you\'re off on to something else, the capacity of home chargers.
From what I see level two chargers top out at about half that, so take
it up with the EV car companies and charger manufacturer\'s without
regard to using the car to power the house in an emergency.

I fit what I want to fit, not what they want to fit. My house, my wiring. Easy enough to get a 24kW commercial charger destined for a car park and wire it to your house.

So if you were to go higher than that your going
to need new wiring from the garage or wherever, back to the panel. So add that to the list
of why 10KW is reasonable and would cover the vast majority of what people actually
would do with it.
Park the car nearer the house.

I was talking about the car being in the garage. That\'s where the vast majority of
chargers are going to be located.

A garage is for storing things and for a workshop. The car lives outside.

You still need wiring from there back to the panel
to support the max amperage.

You do that at 240V, so not expensive.

> Thinking this through, it seems likely **that** you will

Don\'t use surplus words.

need a separate, additional run from the inverter back to the panel to do the standby
power anyway, so add that to the costs and obstacles.

No, use the same cable, electrons will go both ways.

Or I can buy a generator
that will run indefinitely on gasoline or natural gas for under $1000 and that
doesn\'t require the car to remain in the garage for the duration.

Noisy, and prone to not starting. I hate one cylinder \"engines\".

No, but i want DC anyway. Even after rectifying, it hardly get over 220V DC. So, i use two sets to get 420.

Wrong again. In the US it\'s a code requirement. I can\'t imagine it\'s not the same
in any civilized country, for very obvious reasons.

Nobody checks that shit, just fit it. You can have a manual switch which will obviously do the same job. In the UK technically it\'s illegal for me to fit a new 13A outlet. WTF?!

No it\'s a safety issue to prevent backfeed from the house into the grid.

You misunderstand. A manual switch would also do the same. And a power transfer switch is just a relay, very cheap indeed. I had one when I tried solar power (which is a dead loss in Scotland, no sun).

A 100 amp 240 volt single phase version on Amazon is just under $200. A 200 amp version is just under $600.
$13. https://www.ebay.co.uk/itm/394278647754
Add in a few dollars for the fittings, wire etc. There was a rule of thumb years ago that parts and labor would be about the same amount.
Then fit it yourself.

You need to learn the difference between energy and power. The 80kW is really 80kWh(hours), a measure of energy stored in the battery. The 10kW is a measure of power which is the rate of energy extraction from the battery, usually specified in kW, kilo-watts, thousands of Watts. There is no logical connection between the two ratings. The engineering requirements of the battery EV application determines that.

Here is an authoritative overview:
https://theconversation.com/can-my-electric-car-power-my-house-not-yet-for-most-drivers-but-vehicle-to-home-charging-is-coming-163332

News of a work in progress to make home backup routine with no special equipment required:
https://www.atlasevhub.com/weekly_digest/here-if-you-need-evs-as-backup-batteries/

The cost for equipment to do that is top dollar because they sell so few. There\'s no logical connection between present cost and a hypothetical mass produced product.

Rewrite all that considering I know the difference between power and energy, I have a fucking physics degree.

Then you should have figured out the answer to your question from the article. It says
a bi-directional charger is required. So the inverter circuitry is in a special charger.
What are home chargers built for? The ones I\'ve seen are 240V, 50A tops. That\'s 12KW.
So the charger and cables to the car are to support that, not 80KW.
Cables don\'t cost much, especially if they\'re short.

How short is the cable to go from the inverter in the garage back to the
panel, which could be at the other end of the house going to be? That\'s
where my panel is, at the farthest end of a big house from the garage.

At 240 volts, the cable will be cheap as it\'s thinner than a 12V one. Or you could run it at 400V DC from the car to there for even less, and put the invertor near the panel.

Given that even whole house standby generators are in the 10KW - 15KW range, and portable generators
that people use are typically 3KW to 7KW doing 10KW from a car sounds very good.
It\'s a pest, you have to switch stuff off.

More like just not turn things like a dryer or stove on.

And if there\'s a powercut while they\'re already on? Now you trip the thing and your meal is half cooked and other stuff goes off like your computer and the DVR that was recording stuff.

Could they redesign, at increased cost for higher power? I don\'t see why not, but then
you\'re just going to drain whatever power you happen to have in the battery at the time
you need it faster.
Not if it\'s bursts, like cooking a meal or having a hot shower.

Microwave takes 1200 watts.

More like 1500.

Here in the US the vast majority of homes have
tank type water heaters, most of those are gas, so taking one or two quick showers,
if you really need to, isn\'t a problem. This is for the rare case of a power emergency,
not so you can live like the grid isn\'t down. You do have a point if you have an
on-demand water heater, but given the whole car supply thing is only worth a day or
two, I don\'t see it mattering all that much.

To have the full 24kW would be more convenient, you carry on regardless.

There is no guarantee it will be fully charged.

They usually are.

Obviously that\'s BS, especially since it takes 9 hours to fully charge and that\'s
with a level 2, 240V charger installed in the garage.

That\'s a weak 8kW charger you\'re talking about. And assuming you came home with an empty battery.

The car could be in any
state of charge or not even there when the power goes out. Not being able
to use the car while it\'s being used for power for the house is another obvious
big disadvantage.

If you\'re out you don\'t need power.

If it was plugged in when the powercut started, it would have just been charging.
And unlike a generator, what you have available in a car is very limited, so reasonable people are
going to be OK with a 10KW max because they are going to use it for necessities,
use it sparingly and not want to blow through it at high power usage.
A Nissan Leaf would power the average house for 3 days. And decent electric cars have a battery 3 times bigger.

Not at 80KW and living like you are still on the grid, which is what you want.

I want 24kW, not 80. And I don\'t use that continuously.

The charging hardware is still rare and expensive so surrounding it with
vehicles to charge would make a lot more sense.

It may not be quite as bad as that - the expensive charging hardware is not at the post itself but usually mounted in equipment racks some distance away and is often shared between two or more charging heads.

A few private carparks have the more sensible one charger to serve four
spaces configuration but all too often they are one charger per space.
I see a problem with that. One car charging, another parked and waiting.
When the first one finishes, he leaves and another client is fast and
parks there; sees the cable not been used and takes it, before the car
that was waiting there notices and comes.

...
ChargePoint (and maybe other charging providers) deal with that by instituting a five minute period grace period after the cable is replaced where only the person next on the waitlist can unlock and remove the cable and start charging. Authentication is performed by card or phone app.

Oh.

Nice


Ok, lets go round it a bit more.

I stop somewhere in my trip, the charger is busy, I register for being
next, I go for a coffee, the app alerts me, but it takes me 10\' to get
down from the cafeteria.

:-D


The app should give the warning way before, or give a count down of time
left. Huh, maybe it does.

A post can be read and responded to by anyone. When I said \"And

was talking to, I can\'t tell to help you out now, since you snipped
the attributions.

Many people talk about stuff they don\'t actually know much
about. An EVSE which does zero energy conversion, costs around $400
for 5 kW handling capability.

You need to shop around. I can get one for half the price
that does 8kW. Anyway they have electronics to communicate with the car.

One what? The point is the EVSE doesn\'t \"handle\" the power,
it just connects the car to the power. An inverter is much more
expensive because it has to actually convert the power. So no, $500
is not realistic for 10kW.

But you weren\'t talking about invertors, you said EVSE.

10 kW is around 42 amps. So I can see a 10 kW inverter
being much more expensive than $500. If you think you can make and
sell them at a profit, for $500, you need to go into that business!

LOL!!! Anyone who would wire that Chinese junk to their car

Absolutely, i got a 3kW 48V to 220V for $99. 10kW for $999 is
too expensive.
If you join the outputs together from three of those, would they
phase synch?

No, but i want DC anyway. Even after rectifying, it hardly get over
220V DC. So, i use two sets to get 420.
Why do you run your house on DC?

Car, not house.

I guess most 220V stuff will run DC or AC.

Huh, no.

Yes, you mentioned the 10kW inverter costing a mere $500 and I\'m saying a much more simple EVSE is about that price, performing no conversion of the power and typically only handling 5kW at that price. I was given a BoM and costs for a 30amp EVSE and the $500 price tag is realistic.

Yes, but those of us who want our cars to not burn up, and be responsible for any damage the fire causes, because our insurance won\'t cover that sort of homebrew garbage, don\'t install junk in our BEVs.

It is really hard to have a conversation with you, because you will never concede any point, no matter how clearly it is explained to you.

One requirement is a power transfer switch.
That\'s only for convenience.

Wrong again. In the US it\'s a code requirement. I can\'t imagine it\'s not the same
in any civilized country, for very obvious reasons.

Nobody checks that shit, just fit it. You can have a manual switch which will obviously do the same job. In the UK technically it\'s illegal for me to fit a new 13A outlet. WTF?!

A typical installation would switch to backup mode automatically, so the switch needs to be automatic. But it might be acceptable to use a manual switch if the connection were manual as well. But the transfer switch would be wired so the V2H were not connected unless the grid were disconnected. This could not be done through the regular charging connection as commercial units would do.

Your computer or anything else electronic with switched mode certainly will. First stage is to rectify it, which will simply do nothing. Resistive heating will be fine. Only AC motors will not work.

It\'s very easy actually, and I\'m about to make my own UPS cheaply doing that very thing. And had a similar arrangement when I had my own solar system.

You get a 240V-coil relay and power the coil from the grid. So the contacts move according to if the grid has power.
One contact switches on the invertor.
The other contact moves the load to the grid or the invertor output. Since that contact cannot be in two places at once, the inverter output can never go to the grid.

If an EV has an output power of say 80kW to drive the motors when driving, why is the backup power (to power your house in a power outage) only about 10kW? It\'s the same battery!

And why do people say it costs thousands of dollars to fit something to do this? Surely a 10kW invertor doesn\'t cost much, just something to make 400VDC into 240VAC. I\'d say more like 500 dollars.

I don\'t know who you are talking to.

This is a newsgroup, so I\'m talking to whoever reads the post.

I would have avoided this post, but you seem to be replying to me. Maybe I\'ve made a mistake in that assumption and you are just airing out your fingers.

A post can be read and responded to by anyone. When I said \"And why do people say it costs tho.....\", you didn\'t seem to know who I was talking to, I can\'t tell to help you out now, since you snipped the attributions.

Many people talk about stuff they don\'t actually know much about. An EVSE which does zero energy conversion, costs around $400 for 5 kW handling capability.

You need to shop around. I can get one for half the price that does 8kW. Anyway they have electronics to communicate with the car.

One what? The point is the EVSE doesn\'t \"handle\" the power, it just connects the car to the power. An inverter is much more expensive because it has to actually convert the power. So no, $500 is not realistic for 10kW.

But you weren\'t talking about invertors, you said EVSE.

10 kW is around 42 amps. So I can see a 10 kW inverter being much more expensive than $500. If you think you can make and sell them at a profit, for $500, you need to go into that business!

A grand actually. https://www.ebay.co.uk/itm/193572450281

LOL!!! Anyone who would wire that Chinese junk to their car OR their house is an idiot! Maybe Ed Lee is up for the job?
Absolutely, i got a 3kW 48V to 220V for $99. 10kW for $999 is too expensive.

Yes, Ed Lee, the king of living cheap. Not the guy I would take advice from on this topic. We\'ll see how long it is before you manage to burn up your Leaf... a leaf fire.
You\'ve just admitted you\'re an ignorant money wasting resource wasting upper class twit. You\'re the sort that will die off because you can\'t do anything with limited resources.

Translated into English, that means I won\'t put my car and the people who ride in it in danger of being immolated by excessive frugality.

It\'s kinda funny, Larkin accuses me of being compulsively cheap and Commander Kinky says I\'m too much the spendthrift to survive. LOL
