Why does a car engine still need a battery if it can generate its own electricity?

It needs the battery to store enough energy to restart the engine when it has been turned off. Without the battery you would have to start the engine manually with a crank (as they did on early cars before the invention of the electric starter).
Also, the battery is a critical part of the voltage regulator system for the alternator used in modern car electrical systems to prevent variations in the voltage of the electrical system with changes in engine speed, etc.

What fossil fuel is predominately used in the US to generate electricity?
Coal is still primarily used in the US to generate power (~47% of all electricity generated), however natural gas is being used increasingly to generate electricity (~20% of all electrical generation).
How does a yacht get electricity?
While some yachts employ wind generators or solar panels, the primary method used to generate electricity aboard a sailing vessel is still a generator powered by an internal combustion engine, like a gasoline or diesel motor.
You put a fresh battery in the flashlight but it still would not work?
A source of electricity
If a battery cranks well can it still be bad?
If the battery turns the engine over as it should then the battery is good.
What makes electricity such a useful form of energey?
the thing that makes electricity such a useful form of energy is that electricity is renweable it comes from the skies "thunder" you can also generate electircity but still some things need electricity to help it generate. so......... electircity is a useful form of energy, but also wind, solar are also useful for of energy.
Are vegetables good conductors of electricity?
It depends what you mean by "good" they are not necessarily "good" conductors of electricity but yes they will conduct electricity. Most things conduct electricity at some level, they may have high resistance but they will still conduct electricity.
What is the function of generator in charging a battery?
The generator charges the battery! In an automobile, the battery produces the electricity to start the car. Starting the car takes electricity out of the battery. The car needs to replace the electricity so it will start again the next time. The generator produces the electricity to recharge the battery so the car will start the next time. Cars today use Alternators not Generators. Generators have not been used in autos since the mid 60s. Alternators unlike a generator can still charge a battery even with the engine idling. Alternators are more complex but much better at handling todays high demands for current on modern cars with all the associated electronics.
Why does your battery light come on on the dash and all your instruments go off but everything else still works fine but if you rev it above 1500 rpm they all work again?
It may be your battery. At higher revs the engine is producing enough electricity to power everything
How electricity can help the laptop?
Any computer needs electricity to work. Laptop computers have an internal battery that powers the computer when you are away from your work desk. If you are return to your work desk or the battery is running out of charge you can still attach the laptop computer to mains electricity.
What has the steam engine evolved into today?
It has evolved into steam turbines etc... which are still used to generate power.
Mazda mx3 1994 4 cylinder your battery light is coming on along with engine electrical light sometimes you replaced the battery and the battery light still comes on sometimes along with the engine ele?
Alternator
Is a flat battery a conductor of electricity?
well, yes. It conducts electricity from one lead to the other. Shape has no effect on the battery other than how its made. So you must be thinking of a simple battery cell process, otherwise this would be a silly question. In a simple battery cell, even if your battery was as thin as a piece of paper it would still work but just with very little electricity. So it would have to be as thin as a shadow, meaning two dimensional instead of three dimensional to not conduct electricity.
