Does anyone have a circuit diagram for a charging circuit--->

12V car alternator charging a 12V lead acid battery.......

I want to cut down the electricity bill

The charging circuit will be connected to an inverter that gives an output of 240V AC.

Usually the alternator comes with a built in regulator. If it doesn't have one, you could pick one up at an auto wrecker for cheap. What are you going to turn the alternator with? They require quite a high RPM to give any decent output.

Will use a 220V electric motor to turn the alternator with regulated rpm

And unless your able to run the electric motor for free then you won't save on any electricity.

regulator from van charges battery------>12V battery drive inverter--->inverter drives motor----->electric motor drives alternator----->ac alternator 220V output

Every stage will lose energy via heat. You'll only get a percentage of the original power you put into it.

Gosh I wish schools would start teaching basic practical math and science again.
I really miss the common sense it instills in people.

Why not just pull your 220 off the first inverter? This chain doesn't make sense.

dude....u have to get ur basics right....u cannot continue otherwise

yikes im never going to ask a question on behalf of someone else again.

:eek :

Here's what you could do, but won't really save you any on electricity. Use alternator in Van to charge up a battery while driving, then use an inverter off the battery to get your 220v. Or if you didn't have an inverter you could get a 12v motor, hook it up and spin a 220v generator alternator. Still your paying for the electricity in the gas your using.

hey, its okay fantabulous. even the most experienced guys out there do make mistakes....and making mistakes is the best way to learn...and where is a better place than the forum to make mistakes? where you have experienced people helping you out...so you can always learn from them...dont worry at all...and if its your friend who posed the question, tell him to join the forum too and ask his doubts himself, so he learns too....

cheers,
deepak
