Hello guys,
I am riza working on a charging system project on a lithium ion battery. I want to ask about chargin system using constant current constant voltage method. based on some literature I have read, the method begins with a constant current mode until the threshold voltage is reached and then switches to constant voltage mode until the battery is fully charged. Should the method be made that way, what happens if the charging process starts with a constant voltage mode and switches to constant current mode? Please help the explanation. Thank you

I'm also working on DC fast charger using Only CC mode however i couldn't achieve high constant current. The best method found was using synchronous buck converter with feedback using PID controller however i couldn't tune PID properly any help would be great.
