Hello,

Anyone have any good CV/CC circuit designs used for charging a battery?

Thanks,
Baz1

If you are happy with maxiumum current of 2A then go for L200 voltage and current regulator

HI

FIRST YOU SHOULD SAY WHATH KID OF BATTERY DO YOU USE?
I MEAN 1.2V AA OR 9V OR 12V CAR BATTERY

BETTER SAY VOLTAGE AND CURRENT FOR APPROTIATE TRANSISTOR.
FOR 12V CAR BATTERY CHARGER

Hi Baz1,

have a look at some of the battery charger datasheet from Linear technology.
They provide the block digram for the same.
You could develop from their on.

thanks to everyone for the resources, their helping.

The design is to charge a lead-acid 6 volt battery using a microprocessor for a intelligent charging system.

hi
tell me the current for charging
or
say the name of company and model for searching it's current.

in case of charging a battery
it is good to use half wave rectifier with a series resistor to limit the charging current
this configuration also tricle charge your battery, if your battery is fully charged
