Using two batteries of 12v 75A connected in series to drive a dc 20hp 180v with direct coupling to a alternator to generate electricity. Can simultaneous charging and discharge method sustain the electricity generation?

A DC motor might be 80% efficient. 20hp is14.9kW, which would require 103A @ 180V. You have only 75A at 24V.
Assuming you had 103A @ 180V, you would get 20hp out from the motor.
An alternator might be 90% efficient, so you would get 13.3kW out.
So for 18.5kW input, you have 13.3kW of electricity at the output, and 5.2kW of heat.
Sure you could put the 13.3kW back into the battery, but as you would be taking out 18.5kW, the battery would soon go flat (but you would be warm).

Actually you cannot, because charging the battery is also not 100% efficient.

What it comes down to, is you would be creating energy from nothing, which physics frowns upon.

There is a general rule about physical systems:

You can never get back quite as much energy as you put in.

This is because of efficiency, which is the amount of work that can be done for a given amount of energy. Efficiency will always be less than 100%. This means no matter what you do you will always need more energy than can be gotten out of a machine than it takes to run it.

You can learn a lot more about this, but this simple rule will tell you that if a machine seems to be producing more energy that is being put into it—or even the same amount—you have to look for where that extra energy is coming from.

In the case of a motor that appears generating power to operate itself, there will always be wires connected to a hidden power source. This is usually a battery, so it can be hidden more easily, but it is always going to be there.

Don't let yourself be fooled, learn about physics and the laws of thermodynamics and it will be very clear why these things must be a fraud.

No.
Questions about variations of this scheme are seen here frequently (one variation is to put a wind generator on the front of an electric car) so obviously this idea has been around for a long time.
It's a variation of perpetual motion.
It any of those worked, don't you think we would all be using this magical, free power?

Don't you know there is a massive conspiracy to stop magical, free power. It's called
