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.
Rewrite all that considering I know the difference between power and energy, I have a f****ng physics degree. When I said 80kW I meant 80kW, not 80kWh. Do you seriously think a car motor only draws 10kW?
And that last link doesn't tell you how to do it, just sales waffle about Ford are getting to it.
Pretty easy really, you find the 400V battery wire and connect a convertor to it to make 240VAC.
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.
But you weren't talking about invertors, you said EVSE.
Because I live cheaply on Chinese stuff. 99p for an 18650 battery charger!
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.
A garage is for storing things and for a workshop. The car lives outside.
You do that at 240V, so not expensive.
Don't use surplus words.
No, use the same cable, electrons will go both ways.
Noisy, and prone to not starting. I hate one cylinder "engines".
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?!
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).
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.
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.
More like 1500.
To have the full 24kW would be more convenient, you carry on regardless.
That's a weak 8kW charger you're talking about. And assuming you came home with an empty battery.
If you're out you don't need power.
I want 24kW, not 80. And I don't use that continuously.
