Simple 12 Volt Battery Charger Circuit Diagram

The second simple design explains a straightforward yet precise automatic li ion battery charger circuit using the ubiquitous ic 555.

Simple 12 volt battery charger circuit diagram. Related post lead acid battery charger using lm317 3 battery charger using scr. This is a simple 12v battery charger circuit with indicator circuit is a smart charger circuit. The circuit uses a 0 14 volt 5 ampere step down transformer and a 10 amps bridge rectifier module to convert ac to dc. This circuit is designed to provide charging current upto 3 amps and this circuit don t have reverse polarity protection or over.

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. This design additionally includes a twin indication system in the form of a battery. The relay does not work. Charging li ion battery can be critical a li ion battery as we all know needs to be charged under controlled conditions if it s charged with ordinary means could lead to damage or even explosion of the battery.

I use it for 12v 7ah battery and lower. An automatic battery charger circuit using scr is implemented in this project. This is the circuit of a simple 12 volt battery charger for lead acid battery. Batteries with different potentials like 6v and 9v can also be charged by choosing appropriate components.

Simple 12v battery charger with battery indicator. You are able to ideally take advantage of this circuit for applications such as inverters portable chargers etc. So i use a 2a 12v transformer in the unregulated power supply. The circuit of a simple lm338 solar battery charger is shown below using the ic lm338.

Suppose the voltage battery is 12 4v. The working of the circuit is as. But our charger works on 12v hence with the help of a voltage divider circuit the value of 0 14 volt is mapped down to 0 5 v using resistor r1 1k and r2 500r like have previously done in 0 24v 3a regulated power supply circuit to display the voltage on lcd using arduino nano. Battery charger circuit applications are ideally suited with this ic and we are going to study one example circuits for making a 12 volt automatic battery charger circuit using the ic lm338.

Here is the circuit diagram of a simple and straight forward 12 v battery charger circuit with diagram. If the battery is partially discharged full charge will be attained in one hour. Simple automatic cut off battery charger. It can be used to charge 12v batteries.

You can use this circuit to charge 12v sla battery or 12v gel cell battery and so on. It gives 12 volt and 5 amps current for quick charging of the battery. Referring to the circuit diagram we see that the entire circuit is wired around the ic lm301 which forms the control circuit for executing the trip off. This circuit can be used to charge all type of 12v rechargeable batteries including car batteries.

In load or while in charge is 13v to 15vdc.
