Well, assuming you mean 12V automotive alternators, they will be able to put out about 2500 watts each (160A*15.6V) so for a decent charge rate of 10 kW you would need four. But then you need an inverter to convert 12V DC to 240V AC at 40 amps. There are two technical problems to overcome; one it that you need to regulate the alternator output without a battery for a load, and another is making sure the alternators will share current equally if they are paralleled.hi, how many 160 amp alternators would it take to power (CHARGE) a tesla model s
The reason that the DC-AC conversion is desirable is to provide a stable line frequency for the Tesla chargers. Most of the higher end generators do this now, with an alternator powering an inverter. It's pretty well documented in this forum that Teslas are finicky and have trouble charging on direct AC generators. Here's an example of one of the new generator-inverters: http://powerequipment.honda.com/generators/models/eu6500isRidiculous. Why don't you get a single 240V alternator instead? It's not like the thing needs to be invented. You can go order it now.
I'm scared to ask... what is powering the alternators?
@jossamer
To my knowledge, there is no existing support for charging the battery while the vehicle is in motion - with one exception: regenerative braking. If you're tying into that system, then you have that door opened for you already. If not, then something new and interesting has to be meshed with the Tesla design.
As for power, the display of the Model S on a P85 shows 320 kW as the last tick of the "consumption" (top) half of the power meter to the right of the speedometer. While that value isn't an upper limit for the peak power that you can sometimes squeeze out of a P85, it's a decent metric for some math.
Does your ((V*A)*generator_count) come near (or above) 320 kW? If yes, then you can support a "floored" P85. If it's at or above 160 kW, you're probably still in pretty good shape.
I have no idea if any of this helps, but I tried.
... I cannot say until I go to patent and it is granted.
I was once told there is no free power. U must use energy to create power.
Energy cannot be created. It can only be transferred between different forms.
For example, in a petrol ICE, chemical fuel energy is converted into heat energy and kinetic energy.
In an electric vehicle, electrical energy is stored in a chemical battery, producing heat; the energy is then converted into heat energy and kinetic energy on demand for the wheels.
In all cases the same energy is output as is input, but some is lost as heat. The total energy output MUST equal the energy input.
you are all thinking in conventional the ways of the times we live in, looking in the wrong direction. What I have is simpler than you think, which is why no one has tried it. I hold three patents for items that are not related to this thread. But I know that patent or not once the cat is out of the box unless you have the resources to make it happen the auto makers have the bucks to circumvent you. So with anything like this you have to cash in first because the first year will get you where you want to go. From then on all the car makers will follow suite. This is history, which is why every year the auto makers do their best to keep next years design as secret as possible. look back at all of the year that cars have been made and you will see that once a popular design is out by the following year all the other companies come out with a similar design, including the tesla which looks like a honda or a hundia or even a mecedes they all look the same. I will do my best to keep this a secret until I can make it a reality. my next step is to raise the money to work on it. crysler came out with a design that looks like a bentley. I learned from my first patent that they all wait like wolves to see if you succeed then they all copy. Back in the 80s there was a company called giro that came out with a styrofoam bicycle helmet. it was a hit. by the following year all the other companies had done the same. the game is you do all the work and take all the chances and if it works they follow in your wake, unless of course they can steal it first. point in case the man who invented the television Filo T. Fonsworth. He had a patent for his invention, but the RCA company kept him so busy in court that the man went broke, even took to drink until he was a broken man. I have a design for a car that can turn as many as 16 generators, and no it does not rely on the breaking system. But again my initial question was, how many generators does it take to power a battery pack that can power one to two ev motors in a vehicle like the tesla.

I'm a little confused as to what that video above is about. It looks like a kids toy made of wood. what's the point.
