Car Battery Charger Circuit

Simple automatic battery charger circuit.

Car battery charger circuit. It is designed for 12v batteries. This design additionally includes a twin indication system in the form of a battery charging indicator and a low battery buzzer indicator. This is a simple car battery charger with indication. Posted thursday april 18 2013 unlike many units this battery charger continuously charges at maximum current tapering off only near full battery voltage.

We use the concept of the circuit. This adjustment is done by the 10k preset and a multimeter connected with the output terminals that goes to battery. This is a simple 12v battery charger circuit with indicator circuit is a smart charger circuit. In this unit the full load current of the supply transformer rectifier section was 4 4a.

Car battery charger circuit working principle. You are able to ideally take advantage of this circuit for applications such as inverters portable chargers etc. This ac voltage is rectified and filtered to obtain an unregulated dc voltage used to charge the battery through a relay. The battery is charged from a 230v 50hz ac mains supply.

Not using ics and complicated devices. We can use this circuit for all battery. Now lets see how the entire battery charger design may look including the constant voltage current set up along with the above cut off configuration. Before the use of this circuit you need to adjust the cut off voltage range for autocut.

Just have to understand battery charging requirements only. It tapers off to 4a at 13 5v 3a at 14 0v. The opamp can be a ic 741. So here s the completed customized battery charger circuit which can be used for charging any desired battery after setting it up as explained in our entire tutorial.
