How To Make Automatic Car Battery Charger

On this article I wanna share about my Automatic Car Battery Charger. I call him "Giant". My truly 50 Ampere current output, on maximal condition. This article is continued from my previous article How To Make Automatic Battery Charger 25 A.

But we know that our battery can't accept too high current. Normally, the battery can accept 1/10 battery size from battery charger output. We need to adjust the current flow.

And lucky, my automatic battery charger can do that. My "Giant" car battery charger output is very-very controlled. My Giant also can charge until 10 car battery, with paralel connection. This is very-very flexible current output, the value is depending on the number of battery we charge.

 
How to Make Automatic Car Battery Charger? I build my "Giant" from big size components. There are ; 50 Ampere transformator with 16 Volt and 18 Volt output voltage, 70HF120 Rectifier Diode, and voltage regulator with 50RIA120 as main component.

50 Ampere Automatic Battery Charger

SCR 50RIA120 that can work until 50 Ampere electric current. He is the main gate to flow the battery charger current, when the gate is opened.

SCR BT151 that work until 5 Ampere electric current. This SCR function as 50RIA120 opener.

By this scheme, we will work until 50 Ampere current.

I hope this article will helped everyone need.

NOTE :

1.       we can play on #1 SCR to manage the current.

2.       We need to set TR 4K7 until we get the suitable cut-off voltage output we needed.
