Hi everyone,
I am not very good in electrical engineering and I am having a project which is i don't know where to start and how to build it. Can u please give me a hand and explain me briefly what exactly do I have to do, I am very appreciate
This is the topic----->>>>
Constant current NiCad battery charger: NiCad batteries are relatively simple to charge; for
standard slow charging they merely require a constant current at C/10 (10% of the rated
capacity) for 14 - 16 hours, most NiCad batteries also support fast charging whereby a constant
current source at C/5 is applied for 7 - 8 hours. Ideally such chargers should also include some
form of electronic control that monitors temperature and cell voltage to prevent overcharging
and/or overheating. For this project, though, you only need to design a single BJT transistor
based constant current source capable of supplying a fixed current of ~100 mA to a low
impedance load, independent of supply voltage and load impedance variations (within
reasonable limits).
