Generator Size to Charge an Electric Car

You just plug it in to charge it....of course you have to have a charging dock hooked up...Unless you're livin' out in the woods, then the Leaf may not be the best choice...

The USA have a version of the UK's Top Gear TV program. They did a feature on the Leaf, quite funny when the presenter says he's got enough charge for17 miles, he then checks the sat-nav which informs him the nearest public charging station was 70 miles away.

I now know there's no point in posting the BBC I-Player link as for some reason it's not available to you.

Yes the British version is available here, I watch it all the time...luv it....hate the american version, but it's still early....I saw the episode your talking about, they are hilarious...I think soon these charging stations are going to be everywhere...

Try looking at utub a number motors turning generators all work, as long as the

generator puts out more power then the motor needs. the extra power for what

ever needed.

Yes we know that! The point of a generator is that you never have to plug it in.

you can drive across the country and never have to charge it.

Best to plug it in to an outlet and charge it. If you have to lug a petrol-powered generator around you are missing the point and wasting a lot of money and creating more pollution than a comparable car running on petrol alone.

If you REALLY have to, then check the charge current requirements for the standard home charger and match that up to a generator (1kW sounds too small to me).

If you want to charge up on the move using an alternator connected to the vehicle's electric motor to charge up the batteries this won't work (see previous threads on CR4 regarding electric vehicles, overunity systems and basic electric generator theory).

No not the Car motor! The generator will have its own elect. motor! and yes it will

work it has been tested. you may be right that it may be to small!

So much for the generator theory!

no larry

but most if not all AC drive electric vehicles have regenerative braking which improves battery range by 12 - 35 % depending on how many hills and how many stop starts you have .

Am I mis-reading this?

Where's the gas motor to run the generator?

You did know there was 3 patients on this in the 1940s. Yes elect. motor turn a

generator and the generator run the motor.

"So a small 1000 watt gen powered 2 hp elect. motor, the elect. motor powers the generator, the generator powers the the charger & elect. motor. when charged motor shuts down, when needs charged Battery pack will spin motor till generator take over."

I wonder if he's the right man for the job.

i had wondered about a small generator inbuilt into an electric car , it would run only as back up when you park somewhere that has no plug in recharge points.

just not really sure if its worth it considering the risk that people may try to run it in an underground parking garage and cause toxic fume hazards , plus the risk factor of having an unattended fire hazard

these days many shopping malls have EV recharge points anyway

Wait, are you thinking you can make this thing into a perpetual motion machine by having the car power thar generator to power the car? LOLOLOLOLOL!

Well it must work otherwise why would there be hundreds of videos on U-tube that show it working, its a conspiracy I tell you!

I must say this generator is small for the electric car. My next project is a lot bigger

I have drawen plans to build a houseboat 16' wide x 66' long, to power everything

on it, I will need 2- 3,300 watt generators 110 volts and 2- 5 hp elect. motors 220

volts. By taking 110 volt from ea. generator it would give ea. motor 220 volts witch

gives more power and use less power to run it. So the total unit 220 volts turn out

6,600 watts. It will have 2- 12 volt starter motors/16 amp DC Alternator to spin

start the generators.

Why not just give your money to charity?

You don't have a clue about basic electrical and mechanical power or working principals do you?

First off you cant just wire two 110 AC generators in series and get double the voltage unless you have a way of perfectly synchronizing the shafts together otherwise you will get a useless stumbling waveform that slowly varies between 0 and 220 volts.

Second two five hp electric motors with typical 85% running efficiency will take about

8800 watts to run which is already well past what your pair of 3300 watt generators put out as is. Also don't forget that electric motors have a high inrush power requirements while they are getting up to speed which can easily be 4 - 6 times their running power. No way in hell will two 3300 watt generators provide 35,000 to 53,000 watts of power the pair of motors would need to start at the same time or the 17,500 to 26,500 watt it takes just for one to get started.

From personal experiance, I have an old 10,000 watt military gen set with a 20,000 watt surge rating and it can just barely start my 5 Hp air compressor despite having a 4 cylinder 35+ hp engine powering it.

Lastly the generators themselves are at best about 85% electrically efficient which means they need a mechanical energy input of around 3900 watts or 5.3 Hp minimum to work at full output and considerably more if they have any surge capacity ratings at all.

If you can build such a system and prove it works feel free to post the full blueprints and schematics here for review along with videos and opportunities for any of us to inspect your design in person. Trust me if you do that there are a number of us here who will happily bring you a million dollars in cash each for your efforts.

Can I borrow some of these ideas?

I've got an idea for a pump:

What do you think????

SEE? Brilliant thinking outside the box, or cup, in this case. Why didn't I think of hooking up an Etch-A-Sketch to my computer long ago?!? Didn't take you long to draw it lyn. You must have a lot of practice.

You'd be amazed at the things I have rattling around in my brain straining to get out!

I once built a whole boat in my brain. Only problem was I forgot to imagine the bilge plug and the blasted thing sank while I was asleep.

Thought I'd try my hand at the Etch-a-Sketch thing with a self-portrait, since I see my face a lot, I don't need a model to sit for me.

Your rendering has vanished. Either that, or you're invisible.

You know that happen to me once I was building a skyscraper I got to the 150 th.

floor and I forgot to imagine a foundation under it and the dam thing fell over.

It killed me!

That explains everything.

actually with these new osmotic ? membranes working as a pump your high tech cup might be able to work

very very slowly

lol

did i spell that right ? . not sure if i had the correct big word there Osmosis ??

More like wicking, I'd say.

but wait ! . water can run uphill

I believe it's called a VOLT, from General Motors. Extended range electric vehicle, or EREV. You can buy three Yaris' for the same price.
