i would like to build a car battery charger, which will cut off the charging phase automatically when the battery is fully charged.
can anyone give me some ideas or tutorials on where to start?

I have build this charger back in 1993, it its working !!!!!!
Using a fully charged battery adjust the "P" until the Green LED just about start to go ON. ~14v~

This circuit is from Hobby elektronika 1991/11

Good luck

Texas Instruments and others make ICs designed for this purpose, such as the UC3909 (for lead-acid batteries): https://www.electro-tech-online.com/custompdfs/2003/11/uc3909.pdf

And here's an app note describing how it's used:https://www.electro-tech-online.com/custompdfs/2003/11/slua058.pdf

You don't need to make the letters lowercase. whether or not you use uppercase or lowercase is completely ignored. Web links DO NOT CARE and you can mix it up any way you care to.

You may get a suitable circuit from National Semiconductor Data Sheet for LM350/150. I've built this and now it is up & running.
