If I want to convert this car into a Electric Vehicle...
How much energy do I need?
Some days ago I searched for info about the energy conversions.
I read that the HP (horse power) of my car is 100.
So, in watt is 100 * 736 = 73600 Watt
(I think that the HP is 100, I'm not sure)
So... How much amount of energy could need a minicar like the one that I show in the picture?
How can I calculate the amount of energy that I need to run the car?
I think that I need to calculate the weight, max speed and other factors to know how much energy needs the car
In this video you can see better the microcar:
http://www.youtube.com/watch?v=cIlVgaWeopM&feature=related
How much energy you will use when 100hp car - its depends about your driving style and where you will drive,
As I remember 100 hp = 74.57 KW but does not matter right now,
1J=1W/s. 1Wh=3600 J and so on ...
Before to start with 73.600W electric car ... khm...khm ... how old you are? ;)
Lets suppose you will use 72V system - then your motor and controller both need to be able for current like 1.022A - it is when your right leg is fully straighten on the throttle pedal :o
Lets supose you will choice 144V - then amperage you will need is ca 511A,
When 400V - then 184A ... this is more realistic ... but are you able for these kind of figures in real life?
Even 144V of DC can kill you instantly - I really hope you will not tuch,
When Batteries are common lead-acid 75 A/h - then you can drive this electric car ca 15 min when heavy racing ;-)
And you will need "only" 33 series common car accus :o
Best regards,
khabe
Im back from garage - one 75 A/h lead acid battery weights 28 kg,
33 x 28 = 924 kg total ... my God :o
But ok - I have several Lithium accus too ... just a minut ... will back soon
so ... 5000 mA ( 5 A/h) 37.0V Lithium polymer 10s pack weights 1.2 kg cost was ca EUR 550,
I have tens of similar packs 5s, 6s, 10s and 12s - lot of money need to be spent if you like to do at least something :(
OK, this 10s pack is able to: 108A continiuous , 147A sustained and 245A bursts
To have 185V we need those units 5 series, to have at least 100 A/h we need 20 parallel ...
Total 100 amd ... again 1200 kg,
Now we have 100A/h , 185V and amperage could be more than 2000A continiuous!
But now we calculated for 185V - means at least 400A for get 100 hp ...
Even if we find adequate controller - we can drive not long time with this car - a quarter of hour maximum ...
Lithium polymers you never can use up to end - comes fire!
hereby I give up the crown,

Hello
For this lightweighted car 10 KW might be enough for the town.
Other Cars like aixam came with 4 HP

Of course, self-evident, but Magnethos asked about 100 hp ;D
gruss,

Thanks for your replies.
Well I said that I think my car is 100 HP. But I want to start the project with the microcar because it requires less energy.
I won't use batteries, of course. They are very heavy and expensive.
I asked that because I'm building an electromagnetic engine. Now, I can run a bedini motor without batteries, I'm building a device to supply energy to the bedini motor. I don't know where the energy comes from, but I'm able to run a bedini motor without batteries.
Hm? ::)
I have not deepen indagated in to Bedini?s motor but when you like to use Newman?s one then at least 100 units will be need to drive it the same like 10kW brushless motor does it.
And BATTERIES ANYWAY !!!! >:(
Have you seen Newman?s video where his at least 1T monster installed on to Van? Top speed was amazing - near 10km/h !!! :'(
Lets calculate:
Each Newman`s unit needs at least 1 km of awg 32 wire - total 100 km of wire ... holy rumpus !!!!!! :o
At that you will need 100 grand magnets, 100m2 playwood ... >:( ...
:-\
Do you have any sketch about bedini?s you planned to install on to this nice car?

The Mini Cooper went like a rocket, (see "The Italian Job") and was only 65HP.
You don't need 100HP. The tyres would not take it.

@Magnethos
Ones we had a member here called mike
He shows a video from a bedini motor,that was working like
in overunity mode and was feeding a capacitor the same time.
Them we have a member named magnacoaster. He has a unit
to sell, that should be able to supply lots of power.
But since some time he ist lost in some isolation.
So if you have a new koncept to drive a bedini in a verry efficiant way, please
share with us and show some pics or a circuit sketch.
I and shure some others too would like to replicate your design
to build you a valid reference.
Cant wait to see some details

@helmut
I think that I can't run a car with a bedini motor directly. But I think that I can extract energy to supply energy to an electric motor. I don't know. I have to test a lot of thing to see if my idea works or not. Is pure theory. Now, I'm going to build a device to supply energy to the bedini motor, using this device I can get a good amount of volts and some miliAmps. I know that newman motor is perfect for this project, but I want to use Bedini for some reasons. I have seen videos of bedini motor @ 3 mAmps.
And I repeat, this is pure theory. I must build the devices and make a lot of tests to see the results.
PS. I have seen the car running with a newman motor but the van was extremely slow. More info about that video?

Electric car don't need 100HP, in fact only 20HP will do like a 130HP, since motor lose a lot of energy in heat, most of the power is wasted.
All DIY electric car usually use 20HP to 40HP motor, very good motor here -> http://www.go-ev.com/images/002_07_ImPulse_9_Sales_Sheet.pdf
Magnethus early VW 36 hp ICE very low efficiency electric motor much higher efficiency would not surprise me 10hp electric [or less] drives early VW like ICE Chet PS did you know magnacoaster?

Lol, what a bs! The hp indicated of an ICE, is the effective motive power of the motor.
Sure you can run a car with a smaller motor, and you can easily calculate what will be your max speed with it.
But then you could also take a smaller ICE. The problem then is, you will not have much accelleration force anymore, when already driving with some speed. If you can live with that, you can take a smaller engine.
But usually small electric cars, have a very leightweight design. And this car, was designed for an ICE. So it's not that lightweight as it could be. But anyway, you can convert anything, you just have to tell, how far do you wanna be able to drive with this thing, how fast you wanna be able to drive this thing, and how much accelleration force you actually still want to have to get there...The rest is simple math...
One more question...
Can a Bedini motor run with 2 or 3 miliAmps?
SHANTI "Lol, what a bs! The hp indicated of an ICE, is the effective motive power of the motor SHANTI " sounds like something got lost in the translation ? you are saying the same thing just more words Chet

BS indeed, EV mass are higher on DIY car not the opposite, the batteries, 75lb * 24 = 1800lb in batteries. ITs twice as an ICE motor, EV motor is around 150lb.
Total mass for EV is greater!
One possibility I like is to convert the drive train of the Twin to be the drive
train of one of those compressed air driven cars. Then add a two wheel trailer
with the overunity power supply and a 120/240 volt inverter. The compressed
air cars have a built in air-compressor that can plug into a utility line. In this case
just plug it into it's trailer. For running around town, park the trailer and recharge
in the evening, for going long distances; take the trailer along and recharge
continuously or stop along the way depending on the power available from your
overunity supply. Lots fun and all free.

LOL, one would usually never use that much batteries on a EV, if you don't want to go in a very high price segment, like the Tesla cars...
What I meant is, that usually the electric cars, are constructed lightweight. Which means the chassis is made e.g. out of plastic compund materials, etc... To have as little total weight as possible. Sure the batteries and also the motor will have quite some weight, therefore it's even more important, that the rest of the car is as light as possible. This is the reason why usual EV are just small cars for driving a little bit around in the city, but not as a replacement for a car one would go on the highway for high speed or some longer distances.
But if you take this car, for a replacement, you have the problem that already the chassis is very heavy, which is quite a problem for an electric car...
If we do a calculation about the 10KW Motor.
Just for example lets say the motor will run with 120Volt then we need 11 batterys.
10 for the drive and 1 for the system.Size: B x H): 350 x 166 x 174 mm
Lets assume,we take Panasonic 12 Volt 65 Amps the weight each is 23 kilogram
That makes a total of 253 Kilos for the light version and the Batterys might fit under the backseat.
120V*65 Amps gives out about 7.8KW/h
Might be a good Car for the city

You are not living on the same planet as us. a lot of peoples using 20 batteries and more, some use pickup, some car etc... They are no limit of what you can do, the only limit is your imagination, which is something you seam to not have.
In case you did not understand, a am talking about DIY car, you can do it with any car you want, the limit is your imagination.
Instead of bullshitting try to be helpfull and stop to be an asshole.
One reason overunity motors are not a good match for vehicles is that a vehicle needs a very high
"energy slew rate" they need engines that can change energy production/conversion rates very rapidly over time.
It's much nicer if overunity power supplies can be run at a constant fixed rate over time. Doing an electric,
or hybrid or fuel cell vehicle correctly is a design challenge best left to the big boys. And at least the big
boys are doing it, and I think America has an economic future because of it! It's the hydrocarbon folks
that don't have any place in energy future. We need to get rid of all the energy middlemen.
"Safe, Clean, Efficient Natural Gas" => but they won't be saying that anymore a few years from now.
:S:MarkSCoffman
@ mscoffman, well said. The electric vehicle is the only future. High gas prices have finaly produced the demand for that supply. All the major auto manufacturers are killing their development teams to get something worth buying into the market. Toyota can't make the Prius fast enough. They are doubling production in Japan as well as have plans to triple it once the Mississippi plant come on line. Every other manufacturer would love to steal the market that demands three auto manufacturing lines (approx. 800 cars per shift x 2 shifts x 3 lines per DAY)!
So electric vehicles are the future. Of this I am certain.
Hybrids are a transition. And they may be necessary for quite some time at least for long distances until an electric vehicle recharge infrustucture is in place.
Petrol based vehicles and even hybrids will still have a place only in less developed areas where the electrical supply is not available. Those places may exist on this planet forever.
