Simple 12 Volt Battery Charger Circuit Diagram Pdf

12 volt 10 amp transformer battery charger circuit diagram.

Simple 12 volt battery charger circuit diagram pdf. By proper transformer selection it can be optimized for either 24 or 36v. As the battery gets charged the terminal voltage begins increasing gradually until it reaches the set 14 2 v. While this is an old circuit technique it is optimized for charging higher voltage lead acid battery packs and could be used on other types of batteries as well. This 24v to 36v linear battery charger is long overdue.

Once we attach the charger with the battery voltage drops from the actual supply 14 2 v level to the discharged level of the battery. You can use this circuit to charge 12v sla battery or 12v gel cell battery and so on. So i use a 2a 12v transformer in the unregulated power supply. The circuit uses a 0 14 volt 5 ampere step down transformer and a 10 amps bridge rectifier module to convert ac to dc.

You are able to ideally take advantage of this circuit for applications such as inverters portable chargers etc. This circuit can be used to charge all type of 12v rechargeable batteries including car batteries. Simple automatic cut off battery charger. Also i am wanting to also build a 6 volt charger for a 6v gell type of battery.

Select wattage on your choice. If they are mounted on the same heatsink and will throttle the circuit back if q1 gets too hot. In load or while in charge is 13v to 15vdc. Simple 12 volt battery charger circuit diagram designed by using few easily available components and this circuit is suitable for different types of batteries needs 12 volt.

I use it for 12v 7ah battery and lower. This design additionally includes a twin indication system in the form of a battery. The relay does not work. So the charging current is 2a.

R1 and r2 are high wattage resistor like 2w 3w 5w and could be above. This is a simple 12v battery charger circuit with indicator circuit is a smart charger circuit. Comes to look in the circuit. Q1 and ic requires a good heatsink.

This circuit is designed to provide charging current upto 3 amps and this circuit don t have reverse polarity protection or over. A 12v battery is normally recharged at 14 2 v or 2 40v per cell. This is the circuit of a simple 12 volt battery charger for lead acid battery. It gives 12 volt and 5 amps current for quick charging of the battery.
