Battery Charger with microcontroller

microcontroller battery charger

Hello everyone...

My project tittle is "Smart Battery Charger with Micro-controller".....
i need to charge 2500 mA-hr NiMH AA rechargeable battery which is connected in parallel
and need to be charge in 1 hour or less...
i used LM317 as voltage regulator.....

most of the battery charger i found do not charge battery in parallel but in series....

so how about if i want to charge a battery in parallel...??
means i can increase the number of battery to be charge at any time but still i can control the charging current
so that charging time is less than 1 hour....
how to control (using PIC16F84A) the charging current to the battery if the number of battery are increased or decreased..??
Any suggestions about voltage regulator or anything is really appreciated...
TQ..hopefully somebody can help..

HI

basicly you will need to place a battery charge controller for each batery like the MP2605,and then combine all output into one using LTC4412 for each battery

and control each of them with the micro controller

All the best

Hi
You can find some dedicaced circuits on maxim website.
Max712 or 713, are useful to design simple and low cost battery charger.
