Schematic 12v 10 Amp Battery Charger Circuit Diagram

Comes to look in the circuit.

Schematic 12v 10 amp battery charger circuit diagram. This circuit is for 10 to 20 ok. T1 2n2218 t2 2n3055 bdw21c 1c1 ua741 pt1 kbl04 01 1 socket 8 pins. 1 heat sink for t2. Simple automatic cut off battery charger.

This 12v battery charger circuit with auto cut provides the automatic cut off facility when the battery get fully charged. B1 12 volt battery. Should i change all diodes amp or only the bridge rectifier. To get all the details of the calculations you can refer to the table provided in this article.

There five diodes 4 diodes are rectifier and 5 diode is used between bridge positive and battery positive and all diodes have the same value. Before the use of this circuit you need to adjust the cut off voltage range for autocut. Connect 2 bc547 as shown in the diagram. It gives 12 volt and 5 amps current for quick charging of the battery.

If the battery is partially discharged full charge will be attained in one hour. Compact 12 volt battery charger circuit using ic lm 338. This adjustment is done by the 10k preset and a multimeter connected with the output terminals that goes to battery. Suppose the voltage battery is 12 4v.

For 5 amp range use lm338 instead of lm317 and change 1 ohm to 0 6 ohms. The above circuit is calculated for a 2 amp outpur but you can easily upgrade it for delivering upto 10 amps easily so that it becomes suitable for charging our 12v 100 ah battery. The ah ampere hours of each battery may vary based on the required capacity a 7 ah battery for example will be able to provide 1 amps for a duration of 7 hours 1 amps 7 hours 7 ah. Now if i charge a 50 ah or 70 ah batteries.

So i use a 2a 12v transformer in the unregulated power supply. Q1 and ic requires a good heatsink. 1 heat sink for tl. 12 volt 10 amp transformer battery charger circuit diagram.

The following tested 12v charger circuit schematic was sent to be by ali solar with a request to share it in this post. Most of the lead acid batteries in the market are 12v batteries. Charger s input voltages are 20 volt ac. All resistors are of 1 4 watt unless otherwise specified.

If they are mounted on the same heatsink and will throttle the circuit back if q1 gets too hot. Parts list for the 12v automatic car battery charger circuit. This is the circuit of a simple 12 volt battery charger for lead acid battery. In load or while in charge is 13v to 15vdc.
