Hi all,

Will anybody suggest some intelligent battery charger schematic or idea? What should be the charging strategy if its a uC based charger?

Thanks

For NiCd the constant current algorithm works well. If there is a thermistor on the battery you can use high charging rates, while monitoring the temperature. Otherwise, you will have to use a slow charging method.

Take a look at these two projects:
NiCad AA automatic charger
**broken link removed**
NiCad 87C751 charger
**broken link removed**
The second one is probably a little bit overdone ..
The mcu 87C751 can be replaced with any microcontroller of 8051 core, and software in C is included ..

pic nicad charger

Thank you all.the pages were very helpful.I am studying them now. This is for my final year project.Im supposed to build a usb interfaced battery charger for Ni Cd and Ni Mh batteries,controlled by philips lpc 2148 which is an arm 7 micro controller with usb 2.0.The charger is supposed to draw power from the usb port,can anyone help me with the design of the charging device.

Thank you again,
Sandhya

Sure buddy, check this link:
It's for a lithium Ion battery but can charge NiCads too without modifications.

If you give me the specs (current/voltage) I can draw up a schematic diagram for you as well...
