SIMPLE BATTERY CHARGER CIRCUIT


Battery charger
Now we are going to discuss a Simple Ni Cad Battery Charger circuit. The circuit is wired as a constant current source. It is made possible by using two bjt transistors, 2N2219 and 2N2222. The circuit posses very low internal resistance so the output current is comparatively large (upto 74mA). This battery charging circuit will automatically turned off when the battery is completely charged.




Automatic battery charging circuit diagram


•The zener diodes is used to regulate the output voltage.

•Feed the circuit by a 24V dc source.

•The output will be of 12V, constant current (74mA).

    great work and it's very simple to understand keep up the good work
    i have a question
    could u please tell me the componends i'd have to change if i want to mess up with the voltage or the current if possible thank you
