A 'voltage' regulator should allow a battery to charge. It needs to limit the voltage so the battery does not over-charge and it needs to limit the current so the maximum energy limit from the generator is not exceeded. It may do this by comparing the battery voltage to the generator voltage and limiting the current - hence the regulator must be tailored to the maximum output from the generator. The other way for the regulator to work is to compare the voltage of the battery to a reference voltage and let the generator build up the voltage to that limit. If the voltage reference is just below what a fully topped off battery may be, then you will never try to over-charge the battery. It will at the same time provide some limit to the current to protect the generator.
While generators and altenators work differently the above copied paragraph would still apply.
Most altenators today have built in regulators while a few manufacturers still insist in having the Electronic Control Unit (ECU or computer) control the voltage. This is more precise, but when it stops working, it is harder to diagnose and much more exspensive to replace.

so its a must to regulate the voltage to the battery

it regulates how much voltage youralernater or generater sends to your battery
