12 Volt Battery Charger Circuit Diagram Pdf. It can be used to charge 12V batteries. Charger when the cells are too hot so that the charger will back off until they are cool enough to continue recharging.
This circuit can be used to charge all type of 12V rechargeable batteries including car batteries. The circuit uses a 0-14 volt 5 Ampere Step down transformer and a 10 Amps Bridge rectifier module to convert AC to DC. After that 4A rectifier is used to rectify voltage from AC to pulsating DC.
12 volt 13AH Battery charger.
Figure 1 shows the battery pack prior to disassembly. 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 0-5V 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. You are able to ideally take advantage of this circuit for applications such as inverters portable chargers etc. Once we attach the charger with the battery voltage drops from the actual supply 142 V level to the discharged level of the battery.
