Is that a fake Magsafe2 charger?

No, It is  an original Apple charger

Nobody can help me on this?

There's a good chance it's a custom Apple IC, plus something blew it up so replacing it might just blow up the new part.

Those magsafe connectors don't last, might be prudent just to buy another charger or if you have AppleCare try taking it to an Apple store.

How are you sure that's a genuine Apple charger? Can you post more photos?
