[DML] Re: Car's use of electricty / alternator & battery question



 
 
Dave,
 
The battery is of course used to power the starter for the car.
 
Once started, the car draws power from it's "power source"
 
This "power source" is the parallel combination of the battery and the  
alternator.
 
Usually the alternator keeps up with power demand and it tries to keep the  
battery fully charged. 
 
If you need more power than the alternator can supply then you will be  
draining that power from the battery.
 
Once started you could probably remove the battery and run the car on just  
the alternator, though this would not be a good idea because the battery acts 
as  a regulator as well.

8. Car's  use of electricty / alternator & battery question

Question about the DMC power  usage...

Is the battery used just to start the car; or
Is the  battery used all the time for power and then recharged by the 
alternator;  or
Is the battery used just to start the car and after start up, the car  
draws power directly from the alternator ignoring the  battery?
