What happens if I connect two car alternators in parallel? Can I connect three or four alternators in parallel? I just want a cheap way to increase power. I need 5.5kw for recharging a battery pack.

It may sound crazy but I,m planning(in a near future) to test this connection in an electric vehicle:
1- DC electric motor with a special pulley adapter for connecting two high output alternators
2- alternators to DC/AC converter
3- converter to charger(ev charger)
4- charger to battery pack (96vdc)
Im just trying to extend the driving range!

agabrielauto said:Can I do that and still connect all the batteries in serie to supply the 96 volts needed?
If any of the alternator bodies were to come into contact with each other, it would generate a direct short circuit across a section of the battery pack, and major destruction, death, and/or putting your eye out, might ensue.

agabrielauto said:I can't wait until you explain me how it is posible. I'm always tempted to ask why things happen.
So here goes the question.
How it is possible to charge each battery(with its own alternator), while at the same time have them connected in series to power a controler(or electrc motor 96vdc)??
Isn't suppose to make a short circuit.
OmCheeto said:Eeegads... Just add 6 more alternators. Batteries are like people: they are all different. A dedicated alternator for each battery, powered by regenerative braking, will optimize each batteries lifespan. All these converters will just add unnecessary time and expense to your project. KISS.
But then again, I'm poor...
Good luck.
Solar rules!

Now I know what I can do with that old Chrysler foot that has been laying in my back yard for 17 years
agabrielauto said:As vk6kro said,
"This assumes the batteries are NOT being used in a vehicle while they are charging".
That's my point.
I do want to recharge the batteries while being used. Just like a normal car.
If that,s not possible, then I would have to go back to my first Idea(at the beginning of this forum).
The problem is the bigger alternator I have found is 350 amps.
And I need 500amps or 5.5kw.

RonL said:Sorry Omcheeto,
Should have used a capitol A, Advanced DC, are the motors used in most electric car conversions. They come in power ratings as high as 20 HP.
OmCheeto said:$2740 isn't cheap when you can buy a 7kw gas powered 120/240 vac electric generator for $400.
And if it were easy what you were trying to do, GM and Chrysler wouldn't be bankrupt right now.
I knew that. :tongue:

To connect car alternators in parallel, you will need to first disconnect the negative battery terminals from both alternators. Then, connect the positive terminal of one alternator to the positive terminal of the other alternator using a heavy gauge wire. Next, connect the negative terminal of one alternator to the negative terminal of the other alternator using another heavy gauge wire. Finally, reconnect the negative battery terminals to both alternators.
Connecting car alternators in parallel allows for increased output power, as the combined output of both alternators is greater than the output of a single alternator. This can be beneficial for vehicles with high electrical demands, such as those with aftermarket sound systems or additional lighting.
No, not all alternators can be connected in parallel. It is important to make sure that the alternators have the same output voltage and are compatible with each other. Additionally, it is recommended to use alternators from the same manufacturer to ensure proper function.
One potential risk of connecting car alternators in parallel is that if one alternator fails, it can cause the other alternator to overload and also fail. Additionally, connecting alternators in parallel can also cause voltage imbalances and damage to the electrical system if not done correctly.
Yes, it is possible to connect more than two car alternators in parallel. However, it is important to consult a professional and ensure that the electrical system is able to handle the increased output. It is also recommended to use alternators from the same manufacturer to avoid any compatibility issues.
