Your DG set will have a in-built alternator that will charge
the battery only when it runs.
In case you dont run your DG set frequently, you can have an
external battery charger also.

Answer / rakesh

PROCESS OF "charged the battery in DG" :-
DG GIVE ELECTRICAL POWER(AC VOLTAGE)AND CONVERT THE DC VOLTAGE
AND LIMITING THE VOLTAGE AS PER REQUIREMENT(BATTER VOLTAGE) AND CHARGE THE BATTERY
DISADVANTAGE :-
BATTERY CHARGING DEPENDS ON TIME & AMP. BUT DG ONLY FOR EMERGENCE PURPOSE(SHORT TIME PURPOSE). SO IF YOU CHARGING BATTERY THOUGH THE DG IT VERY COSTLY.
ADVANTAGE :-
SOME PLANT HAVE SOME SYSTEM SHOULD NOT "SHUT DOWN". IN THAT CASE IT HELP TO GIVE SOME TIME

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
