Li-Ion and NiMh Chopper Chager

[phophollety]

Hi Guys..

I'm looking to develop and multiple cell charger for 8 cells, probably based on a dsPIC or PIC18 ( because it has 8 PWMs ).

The basic power supply, would be an iPowIR, supply something about 5V / 10A.

And I'd like to charge NiMh and Li-Ions battery, with a chopper design. Monitoring the voltage over the cell and the current.

If I charge the cells ( both chemistries ) with PWM can I cause any damage to the cell instead of constant current?

Best Rergards guys

Hi
Dose cell charged separate or connected in series?

All the best

Each cell would be charged separated. Thats why I will have lots of current from my supply board.

Soo would be 8 cell been charged separted
