It seems that at high speeds it might be more efficient to just run on the stock gas engine.

Apparently, that's what the Volt does.

[my73737373]

So if you are using a 3000 wait generator then it would be making 25 amps. If that is half what the car is drawing then you say if you had a 6300 wait desil generator 52 amps. Then it would be able to drive indefenatly. So does you car draw about 50 amps at 144 volts wile driving? Is about 50 amps the max standard draw? Will it draw more than 50 amps at 70 mph?

@my73737373

Sounds about right. I have mostly been driving this car on a 72V battery system. Its top speed is 45mph at that voltage. When I ran it at 144V, I got it up to 73 mph.

It runs at about 75-100 amps to just cruise along at 45mph, so 50 at 144V would be about right. It would draw more at 70 mph. Wind resistance becomes the single biggest factor at high speeds. It might be 100 amps at 144v. That's about 19 horsepower.

How many waits is that generator? How big of a generator would you need to drive indefinitely?

[BenjaminNelson]

@my73737373

The generator was rated at 3000 watts, but since it was a free/non-working generator, I had to fix it up myself. I never managed to get the full power out of it.

To drive indefinately, you would need a generator capable of outputting the average amount of energy you use while cruising. In this case, a generator roughly twice as big. I think a generator built from a 500cc motorcycle engine might work well.

Is it possible if i attach a small 8KW Alternator to the engine with certain gears ??

[Bestundesun]

Hi, Can you let me know the connections, I just got hold of a Honda 8 KW generator so I wanted to know how do I connect it.

What batteries should I choose The laptop battery (14.8V | 4400mAh ) at $25 per piece

and lead acid batteryi.e Motorbike Battery (12V) @ $85 SO what do I go for ??

These prices are from India

The engine on the generator I used was 220cc.

The issue with "and connect it somehow to the wheels" is challenging, because this is a front-wheel drive car, and the electric motor is already connected to the drive train. The non-driven rear wheels have no way to attach an engine. A four-wheel drive car could be turned into a hybrid by connecting the engine to only two wheels, and an electric motor to the other two. That's something I would like to try in the future.

can you add a small scooter engine 250cc and connect it somehow to the wheels with chain or somewhat,can this move the car lets say 50km/h
